Description

Male buckle and lock catch

Technical Field

The present utility model relates to a buckle, and more particularly, to a male buckle with a tapping portion for facilitating installation of a connecting strap and a buckle.

Background

When riding outdoors, users generally need to wear helmets for protection. For convenient wearing, helmet belts are arranged at two sides of the helmet, and the helmet belts are connected at chin parts or in chin sides to tighten the helmet so as to prevent the helmet from falling. For convenient wearing, the helmet belt is provided with a lock catch, and the helmet belt is detachably connected through the lock catch. When the lock catch is opened, the helmet belt can be separated to facilitate the helmet to be taken down, and when the helmet is worn on the head, the lock catch is closed to connect the helmet belt to tighten the helmet.

The locking device generally comprises a separable male and female buckle which are respectively connected with a part of the helmet strap. The existing lock catch, the male buckle and the female buckle are only provided with one perforation for penetrating the helmet strap. In order to prevent the helmet from falling off, more than one section of helmet strap is usually required to be arranged at the lateral direction of the helmet (corresponding to the cheek position), and the arrangement directions of the helmet straps are different, so that the binding range can be increased as much as possible, and the helmet is prevented from falling off.

In order to adapt to the multidirectional arrangement of the helmet strap, a separate component is typically required between the clasp and the helmet strap to expand the perforation of the clasp so that it can be connected to the helmet strap in each of the different orientations. This independent component is movably disposed with respect to the helmet strap, which not only reduces the aesthetic appearance, but also increases the assembly process, which is disadvantageous for improving the production efficiency, and increases the cost of the helmet.

Detailed Description

The following examples are further illustrative and supplementary of the present utility model and are not intended to limit the utility model in any way.

As shown in fig. 1 to 7, the main point of the pin 10 of the present utility model is that the tapping portion 12 is provided thereon, so that the connecting strap 30 can be extended in different directions, thereby facilitating connection and tapping.

The pin 10 is adapted to be detachably connected to the box 20. Wherein the pin 10 and the box 20 are connected with the connection strap 30, respectively, and the connection strap 30 can be connected together or the connection strap 30 can be separated by the separable connection between the pin 10 and the box 20.

The pin 10 is provided with a base portion 11 and a tap portion 12. The base portion 11 is a main body structure of the pin 10 for carrying other structures, and its shape is not limited. Typically, the base portion 11 has a block-like structure having a certain volume.

The tapping portion 12 is fixedly connected to the base portion 11 or integrally formed therewith. Preferably, the tapping portion 12 is integrally formed with the base portion 11.

The tapping portion 12 is configured to be used to thread the connecting strip 30 and force the connecting strip 30 to pass therethrough in at least a first direction X and a second direction Y, which are not aligned so that the connecting strip 30 is disposed in different directions, such that a single-strike connecting strip 30 may be tapped in different directions.

In some embodiments, the first direction X and the second direction Y are inclined, and the angle between them can be set according to needs, and can be an acute angle, an obtuse angle or a right angle. In this embodiment, the included angle between the first direction X and the second direction Y is an acute angle.

In some embodiments, the first direction X and the second direction Y are parallel spaced.

More specifically, the tapping portion 12 has a sheet-like structure, and the shape thereof is not limited. The tapping portion 12 comprises a first connection portion 121 and a second connection portion 122. The first connecting portion 121 and the second connecting portion 122 are integrally formed. The first connecting portion 121 and the second connecting portion 122 are used for penetrating the connecting band 30. In some embodiments, as shown in fig. 6, the first connecting portion 121 and the second connecting portion 122 are used to pass through the same connecting band 30. In some embodiments, as shown in fig. 7, the first connecting portion 121 and the second connecting portion 122 are used to pass through different connecting bands 30. Of course, for the present utility model, as shown in fig. 6, the first connection portion 121 and the second connection portion 122 are mainly used to penetrate the same connection strap 30, so that the connection strap 30 extends in different directions to play a role of tapping. In some cases, the user may also put the first connecting portion 121 and the second connecting portion 122 through different connecting bands 30, respectively, as needed, to perform a similar function.

To facilitate threading of the connecting band 30, the first connecting portion 121 is provided with a first through hole 1211, and the second connecting portion 122 is provided with a second through hole 1221. The first and second perforations 1211 and 1221 are spaced apart. Wherein the first connection part 121 is configured such that the connection band 30 extends outwardly in the first direction X when the connection band 30 is penetrated out of the first perforation 1211. The second connection portion 122 is configured such that the connection strap 30 extends outwardly in the second direction Y when the connection strap 30 is threaded out of the second perforation 1221.

Preferably, the first connecting portion 121 and the second connecting portion 122 are used for movably threading the same connecting band 30, and are configured such that the same connecting band 30 sequentially passes through the first through hole 1211 and the second through hole 1221 to change the arrangement direction of the connecting band 30, so that the connection extends outwards along the first direction X and the second direction Y relative to the pin 10.

One ends of the first connecting portion 121 and the second connecting portion 122 are integrally formed, and the other ends are spaced apart, thereby forming a bifurcated structure.

In some embodiments, only the first through hole 1211 is provided on the first connecting portion 121, only the second through hole 1221 is provided on the second connecting portion 122, and no other holes through which the connecting band 30 can be inserted are provided. At this time, as shown in fig. 7, the first connection portion 121 and the second connection portion 122 are preferably adapted to connect different connection bands 30. If the same connecting band 30 is used for threading, when the same connecting band 30 passes through the first through hole 1211 and the second through hole 1221 in sequence, the flat connecting band 30 cannot be smoothly stretched due to the abrupt change of direction, and at this time, the surface of the connecting band 30 cannot be well adhered to the surface of the tapping portion 12. If the male buckle 10 is used in a helmet, the connecting band 30 cannot be attached to the face and is uncomfortable to wear.

In order to avoid that the flat connecting band 30 cannot be well adhered to the surface of the tapping portion 12 when passing through the first through hole 1211 and the second through hole 1221, as shown in fig. 4 and 6, a third through hole 1212 and a fourth through hole 1222 are further provided in the tapping portion 12.

The third and fourth perforations 1212, 1222 are spaced from the first and second perforations 1211, 1221, respectively. The tapping portion 12 is configured such that the same connecting band 30 sequentially passes through the first through hole 1211, the third through hole 1212, the fourth through hole 1222, and the second through hole 1221 to change the arrangement direction of the connecting band 30 such that the connecting band 30 extends outwardly in the first direction X and the second direction Y with respect to the pin 10.

The third perforation 1212 and the fourth perforation 1222 force the connecting band 30 to turn so that the connecting band 30 is attached to both side surfaces of the tapping portion 12 with the same surface, thus enabling the connecting band 30 to extend and turn smoothly and avoiding uncomfortable wearing.

For example, the two side surfaces of the tap portion 12 are referred to as a front surface 12a and a back surface 12b, respectively. When the connecting tape 30 enters the first perforation 1211 with its first surface 30a facing outward, the connecting tape 30 portion between the first perforation 1211 and the third perforation 1212 engages the front surface 12a of the tap portion 12 with its second surface 30b, then the connecting tape 30 turns at the third perforation 1212, after the connecting tape 30 passes through the third perforation 1212, the connecting tape 30 portion between the third perforation 1212 and the fourth perforation 1222 engages the back surface 12b of the tap portion 12 with its second surface 30b, then the connecting tape 30 turns at the fourth perforation 1222, after the connecting tape 30 passes through the fourth perforation 1222, the connecting tape 30 portion between the fourth perforation 1222 and the second perforation 1221 engages the front surface 12a of the tap portion 12 with its second surface 30b, at which time the first surface 30a of the connecting tape 30 faces outward and the same surface of the connecting tape 30 as when entering the first perforation 1211. Subsequently, the connecting band 30 passes through the second pass, and the surface of the connecting band 30 is not transformed.

The third through hole 1212 and the fourth through hole 1222 enable the surface of the flat connecting band 30 to be fitted along the surface of the tapping portion 12, thereby ensuring smooth extension of the flat connecting band 30 to the greatest extent.

Further, the third perforation 1212 is configured such that the connecting band 30 is directed in the first direction X towards the first perforation 1211 when the connecting band 30 passes through the third perforation 1212. In other words, when the connecting band 30 is between the third perforation 1212 and the first perforation 1211, the connecting band 30 is stretched along the first direction X along the length thereof, so that the connecting band 30 does not turn at the first perforation 1211, and further, the connecting band 30 is stretched substantially along the length thereof to be kept smooth.

Likewise, the fourth perforation 1222 is configured such that the connecting band 30 is directed in the second direction Y toward the second perforation 1221 as the connecting band 30 passes through the fourth perforation 1222. In other words, when the connecting band 30 is between the fourth perforation 1222 and the second perforation 1221, the connecting band 30 extends along the second direction Y along the length thereof, so that the connecting band 30 does not turn at the second perforation 1221, and further the connecting band 30 extends substantially along the length thereof to be kept smooth.

To be suitable for the flat connection strap 30, the first through hole 1211, the second through hole 1221, the third through hole 1212, and the fourth through hole 1222 are bar-shaped holes.

In order to make the flat connection belt 30 extend smoothly, the length directions of the third perforation 1212 and the fourth perforation 1222 are inclined at a first angle, the length directions of the first perforation 1211 and the third perforation 1212 are inclined at a second angle, and the length directions of the second perforation 1221 and the fourth perforation 1222 are inclined at a third angle.

The first angle, the second angle, and the third angle may be the same or different.

Wherein the first angle may be a right angle, an acute angle or an obtuse angle. In this embodiment, the first angle is preferably a right angle or close to a right angle.

The second angle is preferably the same as the third angle, which in this embodiment is set at an acute angle.

The first and second through holes 1211 and 1221 are symmetrically disposed, and the third and fourth through holes 1212 and 1222 are symmetrically disposed with their centers of symmetry coincident, for comfort of use.

Further, in order to enhance the friction between the connecting band 30 and the tapping portion 12, several protrusions are provided on the surface of the tapping portion 12. The shape of the convex portion is not limited, and it may be a circular convex or a non-circular convex.

Further, protrusions, such as saw-tooth protrusions, may be provided on the inner walls of the third and fourth holes 1212 and 1222 to enhance friction.

As shown in fig. 1 to 3, the pin 10 is provided with a locking portion 13 engaged with the box 20. The locking portion 13 is provided protruding from the base portion 11. Preferably, the locking portion 13 is integrally formed on the base portion 11. The base portion 11 or the tapping portion 12 is provided with a grommet 14.

The pin 10 further comprises a protector (not shown in the figures). The protector is provided with a plug-in portion which is engageable with the buttonhole 14. By engaging the plug-in part with the socket 14, the protection element can be connected at least partially to the base part 11 along a side facing away from the locking part 13. The protection member being at least partially connected to the base portion 11 means that the protection member may or may not extend beyond the base portion 11.

Preferably, the protector is detachably attached to the base portion 11. The plug-in part can be separated from the base part 11 by being separated from the button hole 14.

The protection member may be used for installation, protection, or brand mark setting, and is detachably disposed on the base portion 11, so that different protection members can be replaced conveniently to meet different use requirements.

The protector is preferably made of a silicone material, which has a certain elasticity.

In addition, the utility model further provides a lock catch, as shown in fig. 1-3, which comprises the male buckle 10 and the female buckle 20.

The pin 10 and the box 20 may be connected in a connection direction Z different from the connection band 30 arrangement plane O.

The pin 10 and the box 20 are connected in a connection direction Z and separated in a direction opposite to the connection direction Z. The connecting strip 30 is then threaded in a plane O transverse to the connecting direction Z.

The pin 10 is provided with a mating lock portion 13, and the box 20 is provided with a latch portion that is engageable with and disengageable from the mating lock portion 13. The locking part can be of an elastic structure or an inelastic structure. Preferably, the latch portion elastic structure is disengaged from the latch portion 13 by elastic deformation.
