detailed description

The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present invention.

For ease of description and understanding, the side shown in Figure 1 in the drawings is defined as the front side of the correction tape, and the side shown in Figure 4 is defined as the back side of the correction tape. For the simplicity of the accompanying drawings, the belt 1 is not drawn in Figures 4 and 5.

As shown in Figure 1, it is a correction tape, including a shell, which is spliced by two shells. Figure 1 shows the internal schematic diagram of the correction tape after the front shell is removed, and it is in an unlocked state. As shown in Figure 5.

The correction tape includes a correction head 4, a pulley 2 and a waste pulley 3, the pulley 2 releases the tape 1, and the tape 1 is recovered by the waste pulley 3 after passing around the correction head 4, and also includes a locking piece, which is arranged in a straight line Reciprocating movement structure, the locking part is provided with locking teeth, and the locking teeth are switched between the locked position and the unlocked position through the linear reciprocating movement of the locking part. In the locked position, the locking teeth are used to lock the pulley 2 and the waste pulley 3 , in the unlocked position, the locking tooth unlocks the pulley 2 and the waste pulley 3.

In this example, in order to simplify the locking structure and improve structural reliability, only one of the pulley 2 and the waste pulley 3 is provided with a matching tooth. In the locked position, the locking tooth is combined with the matching tooth to lock the pulley 2 and the waste belt. One of the wheels 3, the other is indirectly locked, and in the unlocked position, the locking tooth is disengaged from the mating tooth to unlock said one, and the other is indirectly unlocked. Of course, other structures are also possible. For example, both the pulley 2 and the waste pulley 3 are provided with matching teeth. , the locking tooth disengages from the two mating teeth to unlock pulley 2 and waste pulley 3.

The waste belt pulley 3 is provided with matching teeth and a fourth gear 24, and the belt pulley 2 is provided with a third gear 17. The belt pulley 2 is connected with the locking member, and the belt pulley 2 is set to be driven by the locking member to reciprocate in a straight line. In the locked position, the mating teeth are combined with the locking teeth, and the fourth gear 24 is combined with the third gear 17 . In the unlocked position, the mating teeth are disengaged from the locking teeth, and the fourth gear 24 is disengaged from the third gear 17 . This design is conducive to further simplifying the structure, improving structural response and reliability, and can reduce the movement range of the correction head 4, that is to say, even a small movement of the correction head 4 can reliably unlock the locking structure. At the same time, After the correction head 4 is reset, it can be locked reliably. The locking structure of this example is ingenious, compact, stable and reliable in use, and is more suitable for correction tapes. In order to reset the locking member, an elastic member can be used to push back or reset by other structures, which will not be repeated here.

Cooperate tooth adopts ratchet 13, and locking tooth adopts ratchet 14. After this design, when in the locked position, because the fourth gear 24 is combined with the third gear 17, that is, meshed, and the ratchet 14 is locked in one direction, so the waste pulley 3 and the pulley 2 are mutually restrained and fixed, and cannot be rotated easily. , thus achieving the locking purpose.

The locking member comprises one plate or two plates of a first plate 21 and a second plate 22 . When it is a plate, the plate is arranged on the front side or the back side of the correction tape, and the locking teeth are located on the plate. In this example, for the sake of stability, reliability and durability, the main example is the case of two boards. When it is two boards, these two boards are arranged on the front side and the back side of the correction tape respectively, and the two boards are parallel to each other, and the belt pulley 2 and the waste belt pulley 3 are installed between the two boards, locked The teeth are located on the first plate 21 and/or the second plate 22 .

In this example, the two plates are rotationally connected with the pulley 2, and the pulley 2 can be driven by the two plates to reciprocate in a straight line, and the two plates can cooperate with the waste pulley 3 in a linear reciprocating motion relative to each other. Thereby a kind of simple structure is designed, realized that belt pulley 2 can be driven by these two plates to move linearly reciprocatingly simultaneously, and these two plates move linearly reciprocatingly with respect to waste belt pulley 3 and cooperate.

In order to achieve relatively simple linear reciprocating movement and cooperation of these two plates relative to the waste pulley 3, and at the same time facilitate compact structure, the waste pulley 3 includes a wheel shaft 18, and the housings on both sides are provided with rotating fitting seats 11 that are rotatably matched with the wheel shaft 18. Both plates are provided with a second guide groove 20 which is slidingly matched with the rotating fitting seat 11 .

In order to limit the linear reciprocating movement, a limit structure is also included. In this example, the limit structure includes a limit post 19 and a first guide groove 15. The limit post 19 is arranged on the housing, and the two plates are both The first guide groove 15 is provided, and the limit post 19 is slidably matched with the first guide groove 15 to form a left limit. The limit post 19 can also do other functions, such as a tension spring can be set between the limit post 19 and the locking member. One end of the tension spring is connected with the limit column 19, and the other end is connected with the locking piece, and the elastic force for the reset of the locking piece is provided by the tension spring.

As shown in Figure 3, in addition to the guidance of the first guide groove 15 and the second guide groove 20, the guide rail 12 is also included. In this example, guide rails are provided at the positions corresponding to the waste pulley 3 and the pulley 2 of the housing. 12. The guide rail 12 guides and sets the locking piece.

As shown in Figures 2 and 5, the waste pulley 3 includes matching teeth and a core ring 23, the core ring 23 is used to wind the waste tape, the matching teeth and the core ring 23 are respectively located on both sides of the waste pulley 3, locked The teeth are on the same side as the mating teeth. This is conducive to the convenience of structural design and assembly, and at the same time it is beneficial to control the thickness of the structure.

Further, the strip coil of the pulley 2 is located on the same side as the strip core ring 23 . This is more reasonable, avoids mutual interference, and is also conducive to controlling the thickness of the structure.

As shown in Figures 1 and 5, at least one transmission wheel 5 is also included, the transmission wheel 5 is connected with the waste belt pulley 3, and the belt 1 between the pulley 2 and the correction head 4 passes through the transmission wheel 5 and is connected with the transmission wheel 5. Transmission connection, the passing belt 1 is used to drive the transmission wheel 5 to rotate, and the transmission wheel 5 rotates to drive the waste belt wheel 3 to rotate. After this design, the present invention cancels the basic structure that the belt pulley 2 drives the waste belt pulley 3, but innovatively adopts the belt to drive the waste belt pulley 3 to rotate through the transmission wheel 5, because there is no need to keep the belt pulley 2 to drive the waste belt pulley 3 Therefore, the relative rotation is avoided, which solves the factor that has the greatest influence on the change of force, and because there is no change in diameter between the belt 1 and the transmission wheel 5, that is, there is no change in the force arm, so the change in force is relatively small. It is not obvious, but generally speaking, the present invention is conducive to the stable maintenance of the force during use during the service life of the correction tape.

In this example, the locking member is provided with an avoidance opening, and the avoidance opening is used to avoid the transmission column 10, which is convenient for assembly.

In this example, there is one transmission wheel 5, and the transmission wheel 5 is provided with a first gear 8, and the waste pulley 3 is provided with a second gear 9, and the first gear 8 and the second gear 9 are meshed and connected. This design is beneficial to adapt to the correction tape with tight space, and has the advantages of simple and compact structure.

In order to further simplify the structure and improve the compactness of the structure, in this example, the belt 1 between the pulley 2 and the correction head 4 is connected around the transmission wheel 5. When the belt 1 moves, the belt 1 drives the transmission wheel through the contact connection. 5 turn.

The side where the non-covered layer of the belt 1 is located is connected in contact around the transmission wheel 5 . This design is beneficial to avoid the covering layer of the belt 1 from sticking to the transmission wheel 5 due to contact connection, thereby helping to ensure the performance of the belt 1 .

The transmission wheel 5 is provided with a friction-increasing part 6 , and the friction-increasing part 6 is in contact with the belt 1 . This design is conducive to increasing the contact friction force, and is conducive to ensuring the driving effect of the belt 1 to the transmission wheel 5. In this example, the friction increasing part 6 adopts a friction ring, and the friction ring is sleeved on the transmission column 10 of the transmission wheel 5 .

As shown in FIG. 1 , the transmission pulley 5 is located between the pulley 2 and the waste pulley 3 , and is located on the side where the pulley 2 releases the belt 1 . This is conducive to the structural layout in the correction belt with tight space. In addition, it is beneficial to increase the contact area of the contact connection between the belt 1 and the transmission wheel 5 as it is used, so it is more conducive to ensuring the transmission of the belt 1 pair. The driving effect of wheel 5.

The first gear 8 and the second gear 9 are all located on the back side of the correction tape, and the space on the front side of the correction tape is used as an accommodating space for the movement of the tape roll 16 and the belt 1, and the rotating shaft of the transmission wheel 5 extends to the front side. A transmission column 10 is provided, and the transmission column 10 is connected with the belt 1 in contact. This design, on the one hand, facilitates assembly, and on the other hand, the structural layout in the correction zone with tight space is more reasonable to avoid mutual influence.

In this example, it also includes a guide piece 7 for increasing the contact area of the contact connection. In this example, the guide piece 7 turns the belt 1 so that the belt 1 wraps around the transmission wheel 5, so that the contact area of the contact connection is larger and more flexible. It is beneficial to ensure the driving effect of the belt 1 to the transmission wheel 5.

In addition, the transmission pulley 5 is located between the pulley 2 and the waste pulley 3, and is located on the side where the pulley 2 releases the belt 1, and the lower side of the pulley 2 is provided with a belt for wrapping the belt 1 around the transmission pulley 5. Guide 7. In this design, only one guide member 7 is needed to achieve the wrapping effect, which greatly simplifies the structure and is more suitable for correction tapes with tight internal space.

In addition, the guide 7 is provided with an anti-sticking portion that prevents the covering layer of the belt 1 from sticking to the guide 7 . In this way, although the cover layer of the belt 1 will wrap around the guide piece 7 after the guide piece 7 is guided, due to the setting of the anti-adhesion part, the cover layer is not easy to adhere to the guide piece 7, thereby helping to ensure the safety of the belt 1. Use performance.

In this example, the locking part is connected with the correction head 4 in linkage, and the switching of the correction head 4 in the use state and the non-use state is used to drive the switching of the lock part in the two states of unlocking and locking, and the locking structure The unlocked state of the correction head 4 corresponds to the use state of the correction head 4, that is, press and retreat, and the locked state of the locking structure corresponds to the non-use state of the correction head 4, that is, after the correction head 4 is released, the correction head 4 resets forward, and the locking part also resets forward , the force of resetting is as shown above, can use extension spring, also can be other elastic parts. After such a design, it is beneficial to use conveniently, and whether it is locked or not is realized by the linkage of the correction head 4, which has the advantage of being more convenient to use.

In this example, the specific structure of the linkage connection between the locking piece and the correction head 4 is shown in FIG. 2 . The rear end of the correction head 4 is against the locking piece, so that the rear end of the correction head 4 can push the locking piece to move. After the correction head 4 cooperates with the housing, it can move back and forth along the straight line, and the correction head 4 can move back and forth along the straight line so that the locking part can be switched between the locked state and the unlocked state. Of course, the linkage connection can also be in other structures.

When understanding the present invention, if necessary, the above structure can be understood with reference to other embodiments/figures, and details are not repeated here.

The above is only an illustration of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
