DETAILED DESCRIPTION

[0038] The following description is provided to enable any person skilled in the art to practice the present application. The embodiments described in the following description are only examples of the present application and are not intended to limit the scope of the present application. The principles described in the following description can be applied to other embodiments, variations, modifications, equivalents, and alternatives of the present application without departing from the spirit and scope of the present application.

[0039] For the convenience of illustration and easy understanding, the side shown in the drawings is defined as the front of the correction tape, Figure 1 the side shown is defined as the back of the correction tape. For the sake of simplicity of the drawing, Figure 4 , Figure 4 , 5 The belt 1 is not drawn.

[0040] As Figure 1 shown is a correction tape, comprising a shell, the shell is spliced by two side shells, Figure 1 shown is the internal schematic diagram of the correction tape after removing the front shell, and is in the unlocked state, as Figure 5 shown.

[0041] The correction tape comprises a correction head 4, a tape wheel 2 and a waste tape wheel 3, the tape wheel 2 releases a tape 1 which is recycled by the waste tape wheel 3 after passing through the correction head 4, and further comprises a locking member which is arranged in a straight reciprocating structure, the locking member is provided with a locking tooth, the locking tooth switches between a locking position and an unlocking position through the straight reciprocating movement of the locking member, at the locking position, the locking tooth is used for locking the tape wheel 2 and the waste tape wheel 3, at the unlocking position, the locking tooth releases the locking of the tape wheel 2 and the waste tape wheel 3.

[0042] In this case, in order to simplify the locking structure and improve the structural reliability, only one of the tape wheel 2 and the waste tape wheel 3 is provided with a matching tooth, at the locking position, the locking tooth is combined with the matching tooth to lock one of the tape wheel 2 and the waste tape wheel 3, and the other one is indirectly locked, at the unlocking position, the locking tooth is disengaged from the matching tooth to unlock the one, and the other one is indirectly unlocked. Of course, other structures can also be used, for example, both the tape wheel 2 and the waste tape wheel 3 are provided with matching teeth, at the locking position, the locking tooth is combined with the two matching teeth to lock the tape wheel 2 and the waste tape wheel 3, at the unlocking position, the locking tooth is disengaged from the two matching teeth to unlock the tape wheel 2 and the waste tape wheel 3.

[0043] The waste tape wheel 3 is provided with a matching tooth and a fourth gear 24, the tape wheel 2 is provided with a third gear 17, the tape wheel 2 is connected with the locking member, and the tape wheel 2 is arranged in a structure which is driven by the locking member to move straightly and reciprocally, at the locking position, the matching tooth is combined with the locking tooth, the fourth gear 24 is combined with the third gear 17, at the unlocking position, the matching tooth is disengaged from the locking tooth, and the fourth gear 24 is disengaged from the third gear 17. In this way, the structure can be further simplified, the structural response and reliability can be improved, the movement range of the correction head 4 can be reduced, that is, even if the correction head 4 moves slightly, the locking structure can be reliably unlocked, and after the correction head 4 is reset, the locking can be reliably performed, the locking structure of this case is ingenious and 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 reset or other structures can be used to reset, which will not be described here.

[0044] The matching tooth is a ratchet wheel 13, and the locking tooth is a ratchet tooth 14. In this way, at the locking position, since the fourth gear 24 is combined with the third gear 17, that is, meshed, and the ratchet tooth 14 is unidirectionally locked, the waste tape wheel 3 and the tape wheel 2 are mutually restrained and fixed and cannot be easily rotated, so that the locking purpose is achieved.

[0045] The locking member comprises a plate or two plates, i.e. a first plate 21 and a second plate 22. When it is a plate, the plate is arranged at the front side or the back side of the correction tape, and the locking teeth are located on the plate. In this case, for the sake of stability, reliability and durability, the case of two plates is mainly exemplified. When it is two plates, the two plates are arranged at the front side and the back side of the correction tape respectively, and the two plates are parallel to each other, the belt wheel 2 and the waste tape wheel 3 are installed between the two plates, and the locking teeth are located on the first plate 21 and / or the second plate 22.

[0046] In this case, the two plates are rotationally connected with the belt wheel 2, and the belt wheel 2 can be driven to move linearly together with the two plates, and the two plates can be relatively linearly moved with the waste tape wheel 3. Thus, a simple structure is designed, and the belt wheel 2 can be driven to move linearly together with the two plates, and the two plates can be relatively linearly moved with the waste tape wheel 3.

[0047] In order to relatively linearly move the two plates with the waste tape wheel 3, and at the same time facilitate compact structure, the waste tape wheel 3 comprises an axle 18, and the two side housings are provided with rotationally matched seats 11 rotationally matched with the axle 18, and the two plates are both provided with second guide grooves 20 slidably matched with the rotationally matched seats 11.

[0048] In order to limit the linear reciprocating movement, a limiting structure is further included, which in this case comprises a limiting column 19 and a first guide groove 15. The limiting column 19 is arranged on the housing, and the two plates are both provided with the first guide groove 15. The limiting column 19 and the first guide groove 15 are slidably matched to constitute left limiting. The limiting column 19 can also have other functions, such as that a tension spring can be arranged between the limiting column 19 and the locking member, one end of the tension spring is connected with the limiting column 19, and the other end is connected with the locking member, and the elastic force of the tension spring is used to reset the locking member.

[0049] As shown in Figure 3 , in addition to the guidance of the first guide groove 15 and the second guide groove 20, a guide rail 12 is also included for guidance. In this case, the guide rail 12 is arranged at the positions of the housing corresponding to the waste tape wheel 3 and the belt wheel 2, and the guide rail 12 is used to guide the locking member.

[0050] As shown in Figure 2 , 5 , the waste tape wheel 3 comprises a matching tooth and a belt core 23, and the belt core 23 is used to wind the waste tape. The matching tooth and the belt core 23 are located at the two sides of the waste tape wheel 3 respectively, and the locking teeth are located at the same side as the matching tooth. This is conducive to facilitating the design and assembly of the structure, and is also conducive to controlling the thickness of the structure.

[0051] Further, the belt roll of the belt wheel 2 is located at the same side as the belt core 23. This is more reasonable, avoids mutual interference, and is also conducive to controlling the thickness of the structure.

[0052] AsFigure 1 , 5 As shown, it also includes at least one transmission wheel 5, which is connected to the waste pulley 3. The belt 1 between the pulley 2 and the correction head 4 passes through the transmission wheel 5 and is connected to it. This belt 1 drives the transmission wheel 5 to rotate, and the rotation of the transmission wheel 5 drives the waste pulley 3 to rotate. With this design, the present invention eliminates the basic structure of the pulley 2 driving the waste pulley 3. Instead, it innovatively uses the belt to drive the waste pulley 3 to rotate through the transmission wheel 5. Since it is not necessary to maintain the gear ratio between the pulley 2 and the waste pulley 3, relative rotation is avoided, solving the factor that has the greatest impact on force changes. Furthermore, since there is no change in diameter between the belt 1 and the transmission wheel 5, i.e., no change in lever arm, the force change is less noticeable. In summary, the present invention helps to maintain a stable force during use throughout the service life of the correction belt.

[0053] In this example, the locking component has a clearance opening to allow the drive column 10 to pass, which facilitates assembly.

[0054] In this example, there is one transmission wheel 5, which is equipped with a first gear 8, and the waste pulley 3 is equipped with a second gear 9. The first gear 8 and the second gear 9 are meshed together. This design is advantageous for adapting to the limited space of the correction belt and has the advantages of simple and compact structure.

[0055] To further simplify the structure and improve its compactness, in this example, the belt 1 between the pulley 2 and the correction head 4 is connected to the transmission wheel 5 in contact. When the belt 1 moves, the belt 1 drives the transmission wheel 5 to rotate through the contact connection.

[0056] The drive wheel 5 is equipped with a friction-enhancing part 6, which is in contact with the belt 1. This design helps to increase the contact friction force and ensures the driving effect of the belt 1 on the drive wheel 5. In this example, the friction-enhancing part 6 is a friction ring, which is sleeved on the drive column 10 of the drive wheel 5.

[0057] like Figure 1 As shown, the drive wheel 5 is located between the pulley 2 and the waste pulley 3, and on the side where the pulley 2 releases the belt 1. This arrangement is advantageous for structural layout within the limited space of the correction belt. Furthermore, it facilitates the increasing contact area between the belt 1 and the drive wheel 5 as it is used, thus better ensuring the driving effect of the belt 1 on the drive wheel 5.

[0058] The first gear 8 and the second gear 9 are located at the back side of the correction tape, and the space at the front side of the correction tape is used as a space for accommodating the tape roll 16 and the movement of the tape 1. The rotating shaft of the transmission wheel 5 extends a transmission column 10 to the front side, and the transmission column 10 is in contact with the tape 1. This design is beneficial for convenient assembly and reasonable structure layout in the correction tape with limited space, and avoids mutual influence.

[0059] In this example, a guide 7 is further included for increasing the contact area of the contact connection. In this example, the guide 7 turns the tape 1, and the tape 1 is wrapped around the transmission wheel 5, and the contact area of the contact connection is larger, which is more beneficial for ensuring the driving effect of the tape 1 on the transmission wheel 5.

[0060] In addition, the transmission wheel 5 is located between the belt wheel 2 and the waste tape wheel 3, and is located at the side where the belt wheel 2 releases the tape 1. The lower side of the belt wheel 2 is provided with a guide 7 for wrapping the tape 1 around the transmission wheel 5. This design makes the number of guides 7 only one, which can achieve the wrapping effect, greatly simplifies the structure, and is more suitable for the correction tape with limited internal space.

[0061] In addition, the guide 7 is provided with an anti-adhesion part for avoiding the adhesion of the cover layer of the tape 1 on the guide 7. In this way, although the cover layer of the tape 1 will wrap around the guide 7 after the guide 7 guides, the cover layer is not easy to adhere to the guide 7 due to the arrangement of the anti-adhesion part, thereby being beneficial for ensuring the use performance of the tape 1.

[0062] In this example, the locking member is connected with the correction head 4 in linkage, and the switching of the correction head 4 between the two states of the use state and the non-use state is used to drive the linkage of the locking member between the two states of the unlocking state and the locking state. The unlocking state of the locking structure corresponds to the use state of the correction head 4, i.e. pressed back, and the locking state of the locking structure corresponds to the non-use state of the correction head 4, i.e. released, and the correction head 4 is reset forward, and the locking member is also reset forward. The reset force is as shown above, which can use a tension spring or other elastic members. After this design, it is beneficial for convenient use, and whether to lock is realized by the linkage of the correction head 4, which has the advantage of more convenient use.

[0063] In this example, the specific structure of the linkage of the locking member and the correction head 4 is as shown in Figure 2 The rear end of the correction head 4 abuts against the locking member, so that the rear end of the correction head 4 can push the locking member to move. After the correction head 4 cooperates with the shell, it can move back and forth in a straight line. The back and forth movement of the correction head 4 in a straight line makes the locking member switch between the two states of the locking state and the unlocking state. Of course, the linkage can also be other structures.

[0064] In understanding the present application, if necessary, the above structure can refer to other embodiments / attachments Figure 1It is understood that no further description is given here.
