Description

Hose receiving device

Technical Field

The utility model relates to a hose receiving device having a retaining element with inwardly projecting retaining tongues and a retaining ring connecting the retaining tongues, preferably radially outside, wherein the insertion of the retaining tongues into a hose prevents the hose from being pulled out of the hose receiving device.

Background

Hose receiving devices of this type are used in the hygiene sector for securing hoses against being pulled out. In this case, the holding element is usually fixed to the height of the holding tongue in the hose receiving device, so that a bending of the holding tongue is necessary when the hose is introduced. This requires that the hose to be introduced has a certain minimum strength so that it can bend the retaining tongue when it is introduced. The holding element is usually fixed in the hose receiving device in such a way that the outer side of the holding element protrudes into the inner wall of the hose receiving device surrounding the holding element, in order to prevent the hose from being pulled out, in which case the inner wall is damaged.

Disclosure of Invention

The object of the utility model is to improve the service characteristics of a hose receiving device of this type.

In order to solve the above-mentioned problem, the utility model provides a hose receiving device having a retaining element with inwardly projecting retaining tongues and a retaining ring connecting the retaining tongues, wherein the retaining tongues project into the hose in order to counteract the hose being pulled out of the hose receiving device. In order to solve this object, it is proposed according to the utility model, in particular in the case of a hose receiving device of the type mentioned at the outset, that a stop is provided axially offset from the retaining ring, which stop limits the movement of the retaining element in at least one axial direction.

The fastening of the holding element to the inner wall of the hose receiving device surrounding the holding element (for example, by the outer side of the holding element protruding into the inner wall) can thus be dispensed with. Damage to the inner wall can thus be reduced and/or avoided.

In an advantageous embodiment, it can be provided that the retaining ring connects the retaining tongues radially outside.

As an addition, it can be provided that the stop is in the form of an intermediate ring. Preferably, the intermediate ring can have a trapezoidal and/or rectangular cross section.

The stop can thus be designed independently of the holding element and/or can be adapted to it. The stop can be configured, for example, in such a way that it can optimally transmit the holding force to the holding element and can limit the movement of the holding element in at least one axial direction.

In an advantageous embodiment, it can be provided that the stop is removable.

Thereby, the stopper can be removed for removing the hose from the hose receiving means. The stop can also be replaced in this way.

In an advantageous embodiment, it can be provided that the outer diameter of the holding element is dimensioned such that it can freely fall into the hose receiving device.

The outer diameter of the retaining element may be the outer diameter of the retaining ring. The holding element can thereby be moved slightly in the radial direction inside the hose receiving device. The holding element can also be introduced into the hose receiving device in a simple manner. Thereby, the mounting of the holding element in the hose receiving device is simplified.

In an advantageous embodiment, it can be provided that the retaining ring is flat.

Thereby, the retaining ring can be produced in a simple manner, for example by stamping. Furthermore, the holding element can be symmetrical with respect to a plane oriented in the radial direction. In the case of the installation of the retaining element, the orientation of the retaining element is then irrelevant and the installation is simplified.

In an advantageous embodiment, it can be provided that the retaining tongue ends at the retaining ring.

The retaining ring can thereby connect and/or delimit the retaining tongues radially outside. Thus, a continuous edge can be constructed radially outside. The continuously configured outer side surface can improve the force transmission between the retaining ring and the stop.

In an advantageous embodiment, it can be provided that the retaining tongue is deflected at least 15 ° at its fastening to the retaining ring during the introduction of the hose into the hose receptacle.

The deflection serves to increase the inner diameter of the holding element in order to receive the introduced hose. As an addition, it can be provided that the deflection is at least up to 30 ° and/or at least up to 45 °. In this case, for example, the retaining tongue can be deflected out of the plane of the retaining ring in the initial state, i.e. before the first introduction of the hose.

As an addition, it can be provided that this deflection of the retaining tongue is achieved by twisting the retaining ring.

As a result, a hose can also be introduced and held in the hose receiving device by means of the holding element, the flexibility of which hose may not be able to achieve bending of the holding tongue at its fastening to the holding ring. Furthermore, the fixing position of the retaining tongue on the retaining ring is not required to be bent and potential material fatigue is avoided.

Alternatively or additionally, it can be provided that the retaining tongue is deflected at its fastening to the retaining ring by bending of the retaining ring.

In this way, it can also be ensured that the inner diameter of the holding element increases when the hose is inserted, in order to optimally accommodate the hose. For example, a bending of the retaining ring, in particular in its outer region, can also be associated with the torsion. The deflection of the retaining tongues is not or only achieved by bending the retaining tongues at their fastening to the retaining ring, but rather by twisting and/or bending the retaining ring itself, as described.

In an advantageous embodiment, it can be provided that the retaining tongue protrudes into the hose only when the hose is under tension.

In this way, the resistance can be kept low during insertion of the hose and the anchoring of the hose in the receiving device can only be achieved when the pulling load of the hose actually occurs.

As an addition, it can be provided that the angle between the longitudinal axis of the retaining tongue and the insertion direction of the hose is defined here by the bearing surface of the stop.

Under a pulling load, the hose is pulled back together with the holding element lying against it until the holding element touches the stop. Under a continuous pulling load, the holding tongue can be inserted and/or deflected in the direction of the initial state of the holding element. If the holding element is placed flat on the support surface, the holding tongue is already in a position in which the angle between the longitudinal axis of the holding tongue and the insertion direction of the hose is defined by the support surface, for example equal to the angle between the support surface and the insertion direction of the hose. An angle between 8 ° and 30 ° has been shown to be ideal. If the angle is smaller, the holding element may fold under traction load, and if the angle is larger, the manufacture of the stop becomes more difficult based on the fineness of the structure to be manufactured.

In an advantageous embodiment, it can be provided that the retaining tongue is subjected to compressive stress in the use state of the hose receiving device with the introduced hose.

The retaining tongue itself is then not required to twist and/or bend and does not have to be particularly reinforced in the axial direction.

Alternatively or additionally, it can be provided that the retaining tongue is not laterally acted upon in the use state of the hose receiving device with the introduced hose, at least below a defined tensile stress, between the retaining ring and the free end of the retaining tongue, for example in the direction of the longitudinal axis of the retaining tongue and/or of the retaining tongue.

Thus, the retaining tongue is not required to be twisted and/or bent and does not have to be specially reinforced in the axial direction. For example, the retaining tongue can be subjected to pressure only at its end on the retaining ring and/or at its free end, if the hose has been introduced.

In an advantageous embodiment, it can be provided that the gap width between adjacent retaining tongues and/or the foot width of the retaining tongues and/or the ring width of the retaining ring differ from one another by at most 50%. As an addition, it can be provided that the deviation is at most 20% and/or at most 15% and/or at most 10%. Thereby, it is possible to realize that the foot width and the ring width or the foot width and the gap width or the ring width and the gap width or the foot width, the ring width and the gap width have the same size. In this way, several or all of the dimensions can be selected in a simple manner close to the manufacturing limit value.

Alternatively or additionally, it can be provided that the gap width between adjacent retaining tongues and/or the foot width of the retaining tongues and/or the ring width of the retaining ring differ from the thickness of the retaining element by at most 50%. As an addition, it can be provided that the deviation is at most 20% and/or at most 15% and/or at most 10%.

This can simplify the production of the holding element and can be achieved, for example, by means of a stamping process. This is the case in particular when the individual structural features, for example the features already mentioned, which are to be formed during the stamping process have the same dimensions or thickness as the thickness of the holding element. If the gap width between adjacent retaining tongues is chosen to be small, the effect is obtained that the retaining tongues act well on the hose. If the foot width of the retaining tongue is chosen to be small, a greater flexibility of the retaining tongue over the retaining ring is obtained, which enables easier insertion of the hose. If a large ring width is selected, the retaining ring or retaining element has a high rigidity against twisting and/or bending. The latter may make the insertion of the hose difficult.

In an advantageous embodiment, it can be provided that a sealing ring is arranged axially offset from the retaining ring.

As an addition, it can be provided that the intermediate ring is axially located between the retaining ring and the sealing ring.

Thus, the sealing ring can, for example, directly abut the retaining ring. The sealing ring can also, for example, directly adjoin an intermediate ring, which directly adjoins the retaining ring.

Thus, a force transmission connection can be established between the retaining ring and the sealing ring, optionally via an intermediate ring. The sealing ring is then subjected to axial pressure in the event of an attempt to pull the hose out of the hose receiving device. This results in an increased radial compression of the sealing ring with the hose and can improve the tightness. Herein also referred to as self-reinforcing seals.

In an advantageous embodiment, it can be provided that the retaining tongue is configured radially inward from its fastening to the retaining ring.

Thereby, an excess of the retaining tongue beyond the radially outer side of the retaining ring is not required and the outer side edge of the retaining ring can be revealed outwards.

As an addition, it can be provided that the holding element is constructed flat in the initial state. For example, the holding element can be configured symmetrically with respect to the radial plane in the initial state, i.e. before the initial use in the hose receiving device and/or before the initial introduction of the hose. Irrespective of a possible rotation of the retaining element about the radial axis, the retaining element is always correctly oriented for mounting. This simplifies the installation of the retaining ring in the hose receiving device.

In an advantageous embodiment, it can be provided that the retaining tongues, starting from their fastening to the retaining ring, widen in the direction of the center point of the retaining ring.

This can increase the contact area of the retaining tongue with the introduced hose.

In an advantageous embodiment, it can be provided that the retaining ring is made of metal. Alternatively or additionally, it can be provided that the retaining ring is made of an alloy.

Thus, a material of a desired strength can be selected to manufacture the retainer ring.

In an advantageous embodiment, it can be provided that the intermediate ring is made of plastic. Alternatively or additionally, it can be provided that the intermediate ring is made of a softer material than the retaining ring.

The intermediate ring can thereby be produced in a cost-effective manner.

In an advantageous embodiment, it can be provided that the stop acts on the retaining element at least partially in the radial section occupied by the retaining ring. The loading of the holding element thus takes place not only in the region of the holding tongue or in the radial section occupied by it. In contrast to the force transmission between the holding element and the stop, it is advantageous if the force transmission takes place at least partially in the radial section filled with material of the holding element, as is the case in the radial section occupied by the holding ring.

In an advantageous embodiment, it can be provided that each retaining tongue has a head, the width of which is at least twice that of the foot of the retaining tongue.

Additionally, it can be provided that the width of the head is at least three times that of the foot of the retaining tongue.

The bending stiffness of the retaining tongue is thus significantly increased, since the retaining tongue has only one structurally weakest point, which furthermore occupies only a relatively small radial section.

In an advantageous embodiment, it can be provided that the retaining ring is spaced apart radially from the inner wall of the hose receiving device.

The outer side of the retaining ring therefore does not protrude into the inner wall of the hose receiving device surrounding the retaining ring and is thus not damaged.

As an addition, it can be provided that the retaining ring is radially spaced apart from the inner wall of the hose receiving device under the axial load of the inserted hose.

The radial distance can thus be caused by the insertion of the hose, so that no penetration of the outer side of the retaining ring into the inner wall of the hose receptacle takes place in the case of the insertion of the hose.

In an advantageous embodiment, it can be provided that the stop is supported by the cover. The cover can be fastened, for example, to a further housing part of the hose receiving device. For example, the cover may snap onto another housing part of the hose receiving means.

Thus, a seat is formed for supporting the stop and thus also for axially limiting the movement of the holding element.

In an advantageous embodiment, it can be provided that the bearing surface of the stop adjacent to the inserted hose forms an angle of more than 90 ° with the insertion direction of the hose.

As a result, it can be ensured that the head of the holding element can rest against the stop in a planar manner when the hose is pulled out or when the tensile stress is too great. Thereby, there is no risk that the retaining tongue will fold over and sink under the retaining element. The point of application is as close as possible to the hose. Thus, the hose is further made difficult to pull out.

In an advantageous embodiment, it can be provided that the stop is configured as an inverted symmetrical part.

The stop can thus be inserted or used independently of the orientation direction and the production of the hose receiving device is simplified.

Detailed Description

In fig. 1 a fluid diverting unit 1 is shown, which comprises at least two housing parts 2, 3, wherein the housing part 3 defines the diversion of the fluid. A hose receiving device 4 according to the utility model is formed on the fluid diverting unit 1. A further hose receiving means 5 is provided on the housing part 2. The hose 6 is guided into the guide opening 13 of the hose receiver 4. The hose receiving means 5 has an introduction opening 14. The cover 7 is clamped to the housing part 2 and closes the fluid diverting unit.

In the sectional view of the fluid diversion unit 1 shown in fig. 2 and in the enlarged view shown there, it can be seen that the hose 6 has not yet been advanced up to the holding element 8 and has not yet contacted the latter. The retaining element 8 has inwardly projecting retaining tongues 9 and a retaining ring 10 connecting the retaining tongues 9 radially outwardly. The boundary between the retaining tongue 9 and the retaining ring 10 can be seen, for example, in fig. 5 to 8.

Axially offset from the retaining ring 10, a stop 11, which in the exemplary embodiment is an intermediate ring 16 having a rectangular cross section 12, is formed. The stop 11 limits the movement of the holding element 8 in at least one axial direction, i.e. towards the introduction opening 13 of the hose receiving device 4. Similarly, an introduction opening 14 for the hose is provided on the hose receiving means 5. The movement of the holding element 8 in the other axial direction is limited by a stop 15 formed on the housing part 2. The stop 11 is removable in this case.

Furthermore, it can be seen that a small distance exists between the outer edge of the holding element 8 and the inner wall 17 of the hose receptacle 4, wherein the outer diameter 38 of the holding ring 10 is designed such that the holding element 8 can freely fall into the hose receptacle 4. Furthermore, in this sectional view, it can be seen that the retaining ring 10 is flat. A sealing ring 18 is arranged axially offset from the retaining ring 10 or the retaining element 8. The stop 11 is axially located between the retaining ring 10 of the retaining element 8 and the sealing ring 18 in the form of an intermediate ring 16. The retaining ring 10 is made of metal, which may also be an alloy. The stop 11 in the form of the intermediate ring 16 is made of plastic and thus of a softer material than the retaining ring 10. It can be seen that the stop 11 acts on the holding element 8 at least partially in the radial section 19 occupied by the holding ring 10. The stop 11 is supported by the clamped cap 7 via a sealing ring 18. The locked cap 7 limits the axial movement of the sealing ring 18, of the stop 11 and thus of the holding element 8, toward the insertion opening 13 of the hose receptacle 4.

Fig. 3 shows the fluid steering unit 1 in an exploded view, in which the hose 6, the cover 7, the sealing ring 18, the stop 11 in the form of the intermediate ring 16, the holding element 8 and the housing parts 2, 3 are shown. The housing parts 2 and 3 can be welded to each other. The cover 7 can be fastened to the housing part 2. The retaining element 8 has inwardly projecting retaining tongues 9 and a retaining ring 10 connecting the retaining tongues 9 radially outwardly. The retaining tongue 9 terminates in a retaining ring 10. The stop 11 is constructed as an inverted symmetrical component.

Fig. 4 shows a total of three hoses 20, 21, 22, which are connected to one another via two connecting elements 23, 24. Each connecting element 23, 24 has two hose receptacles 4, 5 according to the utility model, each having a holding element 8, a stop 11 in the form of an intermediate ring 16 having a trapezoidal cross section 25, a sealing ring 18 and a cover 7. Said components being adapted to the hose diameters 35 of the hoses 20, 21, 22, respectively.

In the respective hose receiving device 4, 5 according to the utility model, it can be seen that the retaining tongue 9 protrudes into the hose 20, 21, 22, which counteracts the pulling out of the respective hose 20, 21, 22 from the respective hose receiving device 4, 5.

The retaining tongue 9 is in the use state of the hose receptacle 4, 5 with the introduced hoses 20, 21, 22 and is subjected to compressive stress in this case. While the retaining tongue 9 is not loaded between the free end 26 of the retaining tongue 9 and the retaining ring 10. This applies at least below a defined tensile stress of the hoses 6, 20, 21, 22 and in the lateral direction thereof relative to the direction of the retaining tongue 9 or of the longitudinal axis 39 thereof (see fig. 5).

Fig. 5 shows a top view of a holding element 8 according to the utility model (punched out). Here, an inwardly protruding retaining tongue 9 and a retaining ring 10 connecting the retaining tongues 9 radially outside are shown. The retaining tongue 9 terminates in a retaining ring 10. The gap width 28 between adjacent retaining tongues 9, the foot width 29 of the retaining tongues 9 and the ring width 30 of the retaining ring 10 differ from the thickness 31 of the retaining element 8 by up to 50%.

The retaining tongue 9 is configured radially inward from its fastening 27 on the retaining ring 10, and the retaining element 8 is configured flat in its initial state, i.e. before the introduction of the hoses 6, 20, 21, 22. The longitudinal axis 39 of the retaining tongue 9 has been drawn. The retaining tongue 9 widens from its fastening 27 to the retaining ring 10 in the direction of the center point 32 of the retaining ring 10. The retaining tongue 9 has a head 33, which has a width that is at least twice the width of the foot 34 or the corresponding foot 29 of the retaining tongue 9. These can also be seen in the perspective view of the holding element 8 in fig. 6.

Fig. 7 shows an upwardly curved holding element 8, in which the holding tongue 9 is deflected at least 15 ° at its fastening 27 to the holding ring 10. This state of the holding element 8 occurs, for example, during the introduction of the hoses 6, 20, 21, 22 into the hose receptacles 4, 5 and is formed, for example, by twisting and/or bending of the holding ring 10. However, it is also possible for the holding element 8 to be produced already unevenly in the initial state. This can also be seen in the perspective view of the retaining ring 10 in fig. 8. The deflection can also be at least 30 ° and/or at least 45 °, wherein a greater deflection during the introduction of the hoses 6, 20, 21, 22 is associated with a greater resistance during the introduction.

Fig. 9, 10 and 11 each show a sectional view of the fluid diversion unit 1 together with an enlarged view of the hose 6, the holding element 8, the stop 11, the sealing ring 18, the cover 7 and the inner wall 17 of the housing part 2.

Fig. 9 shows the state before the hose 6 is inserted and reaches the holding element 8, which in the illustration is still in the flat initial state. The holding element 8 is supported on one side by a stop 15 of the housing part 2 and on the other side rests against a stop 11, which is designed as an intermediate ring 16 with a trapezoidal cross section 25. The sealing ring 18 rests on the intermediate ring 16, which rests on the top cover 7. Thus, the axial movement of the holding element 8 is limited in both axial directions. The abutment surface 36 of the stop 11 adjacent to the inserted hose 6 forms an angle of more than 90 ° with the insertion direction 37 of the hose 6.

In fig. 10, it can be seen that the retaining element 8 has been twisted as a result of the introduction of the hose and that the retaining tongue 9 is deflected in the insertion direction 37 of the hose 6. The retaining tongue 9 rests against the hose, but only protrudes into the hose 6 counter to the hose insertion direction 37 when the inserted hose 6 is axially loaded, as is shown in fig. 11. Furthermore, the retaining ring 10 is spaced apart from the inner wall 17. This applies also to the inserted hose 6 present in fig. 11 under an axial load counter to its insertion direction 37.

The axial load of the inserted hose 6, which is present opposite to its insertion direction 37, is a pulling load, under which the hose 6 is pulled back together with the holding element 8 lying against it until the holding element 8 touches the stop 11. The retaining tongue 9 is inserted into the hose 6 under a continuous pulling load. The retaining tongue 9 is deflected counter to the insertion direction 37. Thereby bending or deflecting the holding element 8 back in the direction of its initial state. If the holding element is placed flat on the support surface 36, the holding tongue 9 already assumes a position in which the angle between the longitudinal axis 39 (see fig. 5) of the holding tongue and the insertion direction 37 of the hose 6 is defined by the support surface 36, i.e. is equal to the angle between the support surface 36 and the insertion direction 37 of the hose 6. This angle is about 8 in this embodiment.

It is therefore proposed that, with a hose receiving device 4, 5 having a retaining tongue 9 projecting inwards and a retaining element 8 which connects the retaining tongue 9 preferably radially outwards, the retaining tongue 9 projects into the hose 6, 20, 21, 22, against which the hose 6, 20, 21, 22 is pulled out of the hose receiving device 4, 5, a stop 11 is provided axially offset from the retaining ring 10, in particular in the form of an intermediate ring 16 having a preferably trapezoidal and/or rectangular cross section 12, 25, and which limits the movement of the retaining element 8 in at least one axial direction.
