Abstract
Description
Technical Field
[0001] This utility model relates to the field of stationery design technology, and in particular to a correction tape. Background Technology
[0002] In existing technologies, there are already solutions for preventing the rewind pulleys from rotating in the opposite direction. However, these solutions generally have the following problems: the anti-rewind devices are typically structurally weak, and if excessive force is applied during reverse operation, these devices are easily deformed or even damaged. Secondly, when the correction tape is inverted, placed on its side, or dropped, gravity can cause it to rotate in the opposite direction. Summary of the Invention
[0003] The purpose of this invention is to design and provide a correction belt based on a detailed analysis of the shortcomings of the prior art. This correction belt can effectively prevent the correction belt pulley from running backward. Compared with the prior art, this anti-reverse device has a robust and reliable structure and is not easily deformed or damaged by stress.
[0004] The specific technical solution proposed by this utility model is as follows:
[0005] A correction tape includes: a take-up pulley and a release pulley; a set of anti-reverse assembly is provided on the right side of the central rotating hole of the take-up pulley, including: an anti-reverse wheel; a locking fork, one end of which is provided with a fork head, and the other end of which is fixed to the bottom shell of the correction tape; a sliding inner groove post, the bottom of which is fixed to the bottom shell of the correction tape, and the top opening of which has a sliding groove; the teeth of the anti-reverse wheel mesh with the take-up pulley; and the sliding base of the anti-reverse wheel is inserted into the sliding groove of the sliding inner groove post.
[0006] Furthermore, inside the inner cavity of the correction tape, on the left side of the central rotating hole of the take-up pulley, another set of anti-reverse components is provided; the anti-reverse component includes an anti-reverse wheel two, a locking fork two, and a sliding inner groove post two; the sliding base two of the anti-reverse wheel two is embedded in the sliding groove two of the opening of the sliding inner groove post two.
[0007] The arc-shaped groove walls 1 and 2 of sliding groove 1, and the arc-shaped groove walls 3 and 4 of sliding groove 2 are all centered on the take-up pulley.
[0008] Both the sliding base one of the anti-reverse wheel one and the sliding base two of the anti-reverse wheel two are cylindrical; the sliding base one and the sliding groove one, and the sliding base two and the sliding groove two are in sliding fit.
[0009] The module of the teeth of the first and second anti-reverse wheels is the same as that of the teeth of the take-up pulley. Beneficial effects
[0010] As can be seen from the above technical solutions, the two sets of anti-reverse devices set in the correction belt both include anti-reverse wheels, sliding inner groove posts and locking forks, and the anti-reverse wheels can move within the sliding inner groove.
[0011] When the take-up and take-off pulleys rotate in opposite directions, the teeth of the anti-reverse wheel mesh with the fork of the locking fork, preventing the anti-reverse wheel from rotating. Consequently, the take-up pulley, which meshes with the anti-reverse wheel, also cannot rotate, effectively preventing the correction tape from reversing. Because the locking fork is integrated with the correction tape base, the structure is relatively robust and not easily bent or broken under stress.
[0012] When the take-up and release pulleys rotate in the forward direction, the teeth of the anti-reverse wheel separate from the fork of the locking fork, and the anti-reverse wheel spins freely with the take-up pulley, resulting in very little friction. Therefore, it does not increase the force required by the operator.
[0013] Equipped with two sets of anti-reverse devices, it provides double protection, making its structure robust and reliable, and less prone to deformation or damage. Furthermore, when the correction tape is upside down, placed on its side, or dropped, it will not easily rotate in the opposite direction due to gravity. Attached Figure Description

Detailed Implementation
[0022] To better explain this utility model, the above technical solution will be further described in detail below with reference to the accompanying drawings through specific embodiments.
[0023] A correction tape includes: a take-up pulley 2 and a release pulley 3; a set of anti-reverse assembly is provided on the right side of the central rotating hole 21 of the take-up pulley, including: an anti-reverse wheel 4; a locking fork 42, one end of which is provided with a fork head 421, and the other end of which is fixed to the correction tape base shell 1; a sliding inner groove post 41, the bottom of which is fixed to the correction tape base shell 1, and the top opening of which has a sliding groove 411; the teeth of the anti-reverse wheel 4 mesh with the take-up pulley 2; the sliding base 40 of the anti-reverse wheel 4 is inserted into the sliding groove 411 of the sliding inner groove post 41.
[0024] Furthermore, inside the inner cavity of the correction tape, on the left side of the center rotating hole 21 of the take-up pulley, another set of anti-reverse components is provided; the anti-reverse component includes an anti-reverse wheel 2 5, a locking fork 2 52, and a sliding inner groove post 2 51; the sliding base 2 50 of the anti-reverse wheel 2 5 is embedded in the sliding groove 2 511 of the opening of the sliding inner groove post 2 51.
[0025] The arc-shaped groove wall 1 414 and arc-shaped groove wall 2 415 of sliding groove 1 411, and the arc-shaped groove wall 3 514 and arc-shaped groove wall 4 515 of sliding groove 2 511 are all at the same center as the take-up pulley 2.
[0026] The sliding base 40 of the first anti-reverse wheel 4 and the sliding base 50 of the second anti-reverse wheel 5 are both cylindrical; the sliding base 40 and the sliding groove 411, and the sliding base 50 and the sliding groove 511 are all in sliding fit.
[0027] The module of the teeth of the first anti-reverse wheel 4 and the second anti-reverse wheel 5 is the same as the module of the teeth of the second take-up wheel.
[0028] When the take-up pulley 2 and the release pulley 3 rotate in the forward direction, the teeth of the first anti-reverse pulley 4 are pushed by the take-up pulley 2, and the sliding base 40, which is inserted into the sliding groove 411 of the sliding inner groove post 41, slides to the groove end 412 of the sliding groove 411, away from the fork head 421. The teeth of the second anti-reverse pulley 5 are pushed by the take-up pulley 2, and the sliding base 50, which is inserted into the sliding groove 511 of the sliding inner groove post 51, slides to the groove end 512 of the sliding groove 511, away from the fork 52. At this time, both the first anti-reverse pulley 4 and the second anti-reverse pulley 5 are in an idle state and do not affect the forward rotation of the take-up pulley 2 and the release pulley 3.
[0029] When the take-up pulley 2 and the release pulley 3 rotate in opposite directions, the teeth of the anti-reverse wheel 4 are pushed by the take-up pulley 2, and the sliding base 40, which is inserted into the sliding groove 411 of the sliding inner groove post 41, slides to the position of the groove end 413 of the sliding groove 411 near the fork head 421; the teeth of the anti-reverse wheel 4 mesh with the fork head 421, and the take-up pulley 2 and the release pulley 3 stop rotating.
[0030] When the take-up pulley 2 and the release pulley 3 rotate in opposite directions, the teeth of the anti-reverse wheel 5 are pushed by the take-up pulley 2, and the sliding base 50, which is inserted into the sliding groove 511 of the sliding inner groove post 51, slides to the position of the groove end 513 of the sliding groove 511 near the slot fork 52; the teeth of the anti-reverse wheel 5 mesh with the slot fork 52, and the take-up pulley 2 and the release pulley 3 stop rotating.
[0031] The arc-shaped groove walls 414 and 415 of sliding groove 1 411, and the arc-shaped groove walls 514 and 415 of sliding groove 2 511 are concentric with the take-up pulley 2. This is to ensure that when anti-reverse wheel 1 4 and anti-reverse wheel 2 5 slide within sliding groove 1 411 and sliding groove 2 511, the teeth of anti-reverse wheel 1 4 and anti-reverse wheel 2 5 are engaged with the take-up pulley 2 at any position.
[0032] The module of the teeth of anti-reverse gear 4 and anti-reverse gear 5 is the same as that of the teeth of take-up pulley 2, so as to ensure optimal meshing between the two anti-reverse gears and the take-up pulley.
