Description

Technical Field

[0001] This invention belongs to the field of correction tape technology, and particularly relates to a silent correction tape. Background Technology

[0002] Correction tape is a white, opaque pigment similar to correction fluid. It is applied to paper to cover up mistakes, allowing for immediate rewriting and providing convenience for study and work. The main components of correction tape include: AS (ascorbic acid), PS (polystyrene), resin, and titanium dioxide. The structure includes upper and lower caps, large and small take-up rollers, and a connecting body. The front of the connecting body has a nozzle seat, with the nozzle embedded in it; the rear of the nozzle seat has an upper cap seat; the connecting body has positioning pins; the middle and rear parts of the connecting body have open slots, the bottoms of which are the shaft holes for the small and large take-up rollers, respectively. The large and small take-up rollers fit into the large and small shaft holes of the connecting body, ensuring a smooth and even feed of the correction tape.

[0003] Correction tape requires limiting and fixing the take-up roller during the non-sliding process, and requires releasing the limiting and fixing of the take-up roller during the sliding process. For example, patent (CN109203794B) discloses a coating transfer tool, which includes: a frame, in which a supply reel containing a transfer tape before coating transfer and a take-up reel for taking up the transfer tape after coating transfer are arranged; and a transfer head, which includes a body portion disposed on the front side of one of the long sides of the frame, and has a pressing edge portion at the front end portion that extends in a left-right direction orthogonal to the long side direction and transfers the coating to the transfer surface. The frame or a base member housed in the frame has a protrusion extending toward the transfer head side. During transfer, the protrusion portion presses a portion of the central part of the body portion, including the left-right direction, toward the transfer surface side. The coating transfer tool prevents the coating from being transferred at the center of the pressing edge of the transfer head, thus ensuring ease of use.

[0004] However, the coating transfer tool in the above patent has at least the following defects: during use, it mainly uses the engagement of locking teeth and locking claws to limit the supply reel, and uses the torque generated by pressing the nozzle and the lever principle to make the locking claws move away from the locking teeth; thus, if the pressing pressure is insufficient, the locking claws may not be able to move away from the locking teeth, and the silent application of correction tape cannot be achieved. Summary of the Invention

[0005] This invention discloses a silent correction tape, which mainly solves the problem of insufficient pressing pressure in current coating transfer tools.

[0006] To achieve the aforementioned objective, the present invention provides a silent correction tape, comprising an upper cover and a lower base, wherein an installation cavity is formed between the upper cover and the lower base, a supply wheel and a take-up wheel located on the lower base are disposed within the installation cavity, a swiping nozzle is also disposed at the head of the installation cavity, and a tape-swiping silent structure is also disposed within the installation cavity. The tape-swiping silent structure includes a limiting component connected to the take-up wheel and a guide rail assembly adapted to the limiting component. The limiting component includes a hook and a tooth, and the guide rail assembly is used to drive the hook to move, driving the hook to engage or disengage with the tooth.

[0007] Preferably, the limiting component includes a first mounting groove, a first connecting shaft fixedly disposed in the first mounting groove, a locking tooth disposed at the bottom end of the first connecting shaft, a control component sleeved on the first connecting shaft, and a locking hook disposed on the control component. The guide rail assembly includes a control wheel rotatably sleeved on the first connecting shaft, and the control wheel and the winding wheel are connected by a gear ring structure for transmission.

[0008] Preferably, the inner wall of the controlled component is provided with a first friction part that abuts against the side wall of the first connecting shaft, and the first friction part is used to fix the position between the controlled component and the first connecting shaft.

[0009] Preferably, the bottom surface of the control wheel is provided with a first guide rail, and the hook is provided with a first linkage block located within the first guide rail. The first linkage block can move within the first guide rail to drive the hook to engage or disengage with the hook teeth.

[0010] Preferably, the limiting component includes a second mounting groove, a locking tooth disposed on the side wall of the second mounting groove, a second connecting shaft disposed in the second mounting groove, and a connecting ring sleeved on the second connecting shaft and connected to the locking hook. The guide rail component includes a first guide wheel disposed at the bottom end of the drive wheel and a second guide rail disposed on the first guide wheel. The first guide wheel and the supply wheel are connected by a gear ring structure. The locking hook is provided with a second linkage block located in the second guide rail.

[0011] Preferably, the inner wall of the connecting ring is provided with a second friction part that abuts against the first connecting shaft, and the second friction part is used to fix the position between the connecting ring and the second connecting shaft.

[0012] Preferably, the limiting component includes a third mounting groove disposed on the bottom, a hook rotatably disposed in the third mounting groove, a third connecting shaft disposed in the third mounting groove, and a tooth disposed at the bottom end of the winding wheel. The guide rail component includes a second guide wheel sleeved on the third connecting shaft, a third guide rail disposed on the second guide wheel, and a third linkage block disposed on the hook within the third guide rail.

[0013] Preferably, a third friction part is provided on the inner wall of the second guide wheel to abut against the winding wheel, and the third friction part is used to fix the position between the second guide wheel and the winding wheel.

[0014] Preferably, a column is provided in the third mounting slot, and one end of the hook is rotatably sleeved on the column.

[0015] Preferably, the locking teeth are set at the bottom of the winding wheel via a connecting post, and the third friction part abuts against the side wall of the connecting post.

[0016] The technical solution provided by this invention has at least the following technical effects:

[0017] The silent correction tape disclosed in this invention features a winding wheel that rotates forward during tape application. Guided by the guide rail assembly, the hook automatically separates from the teeth, achieving silent tape application. When the winding wheel rotates in reverse, the hook resets and engages with the teeth under the action of the guide rail assembly, achieving the effect of stopping the reverse rotation. The snapping and separating of the hook and teeth is achieved through leverage without the need to press the tape applicator to generate torque, thus eliminating the problem of insufficient pressing force and making it more convenient to use.

[0039] Example 1

[0040] Reference Figure 1 , Figure 6 This embodiment discloses a silent correction tape, including an upper cover 1 and a lower base 2, forming an installation cavity (not shown). A supply wheel 3 and a take-up wheel 4 are disposed within the installation cavity and located on the lower base 2. A swivel nozzle 5 is also provided at the head of the installation cavity. A tape-swivel silent structure is also provided within the installation cavity. The tape-swivel silent structure includes a limiting component connected to the take-up wheel 4 and a guide rail assembly adapted to the limiting component. The limiting component includes a hook 6 and a tooth 7. The guide rail assembly is used to drive the hook 6 to move, driving the hook 6 to engage or disengage with the tooth 7. The limiting component includes a first mounting groove 8, a first connecting shaft 9 fixedly disposed within the first mounting groove 8, a tooth 7 disposed at the bottom end of the first connecting shaft 9, a control component 10 sleeved on the first connecting shaft 9, and a hook 6 disposed on the control component 10. The guide rail assembly includes a control wheel 11 rotatably sleeved on the first connecting shaft 9. The control wheel 11 is connected to the take-up wheel 4 via a gear ring structure. The rotation of winding wheel 4 will drive the control wheel 11 to rotate, see reference. Figure 2 The inner wall of the controlled component 10 is provided with a first friction part 12 that abuts against the side wall of the first connecting shaft 9. The first friction part 12 is used to fix the position between the controlled component 10 and the first connecting shaft 9. The friction between the first friction part 12 and the first connecting shaft 9 prevents relative rotation between the controlled component 10 and the first connecting shaft 9. (Refer to...) Figure 3The bottom surface of the control wheel 11 is provided with a first guide rail 13, and the hook 6 is provided with a first linkage block 14 located within the first guide rail 13. The first linkage block 14 can move within the first guide rail 13, driving the hook 6 to engage or disengage with the tooth 7. The control wheel 11 and the control component 10 are detachably engageable. (Refer to...) Figure 7 The control wheel 11 is provided with a mounting groove for installing the control component 10. A first limiting surface 28 is provided at one end of the mounting groove, and a second limiting surface 29 is provided at the other end.

[0041] Reference Figure 4 During the tape application process, the winding wheel 4 rotates due to the applied force. The winding wheel 4 then drives the control wheel 11 to rotate forward (relatively forward). The winding wheel 4 and the control wheel 11 are connected by a gear transmission. Since the control component 10 and the first connecting shaft 9 are abutted by the first friction part 12, the control component 10 will not rotate. This allows for relative rotation between the control component 10 and the control wheel 11 until the first limiting surface 28 of the control wheel 11 contacts the control component 10. Only then will the control component 10 rotate with the control wheel 11. However, at this point, the hook 6 and the tooth 7 are separated, achieving silent tape application of the correction tape. (Refer to...) Figure 5 When the control wheel 11 reverses (relatively reverses), since the control component 10 and the first connecting shaft 9 are abutted by the first friction part 12, and without the action of the first limiting surface 28, the control component 10 and the control wheel 11 will rotate relative to each other until the other end of the control component 10 abuts against the second limiting line surface of the control wheel 11. Therefore, the first linkage block 14 and the first guide rail 13 will also move relative to each other. Under the action of the first guide rail 13, the hook 6 will rotate towards the axial position and engage with the locking tooth 7, achieving the function of reversing and stopping rotation. It should be noted that the hook 6 has a movable joint, so the hook 6 can move with the first guide rail 13. This achieves silent tape application when the correction tape rotates forward and stops rotation when it rotates backward. The hook 6 and locking tooth 7 are engaged and disengaged through the lever principle without pressing the cutting nozzle 5 to generate torque. Therefore, there is no problem of insufficient pressing force, making it more convenient to use.

[0042] Example 2

[0043] The difference between this embodiment and Embodiment 1 is that the structures of the limiting component and the guide rail component are different, as shown in the following figure. Figures 8-10In this embodiment, the limiting component includes a second mounting groove 15, a locking tooth 7 disposed on the side wall of the second mounting groove 15, a second connecting shaft 16 disposed within the second mounting groove 15, and a connecting ring 17 sleeved on the second connecting shaft 16 and connected to the hook 6. The guide rail assembly includes a first guide wheel 18 disposed at the bottom end of the drive wheel and a second guide rail 19 disposed on the first guide wheel 18. Multiple second guide rails 19 are disposed and circumferentially distributed on the first guide wheel 18. The hook 6 is also provided with a movable joint, allowing the hook 6 to move with the second guide rail 19. The first guide wheel 18 is connected to the supply wheel 3 via a gear ring structure. The hook 6 is provided with a second linkage block 20 located within the second guide rail 19. The inner wall of the connecting ring 17 is provided with a second friction part 21 that abuts against the first connecting shaft 9. The second friction part 21 is used to fix the position between the connecting ring 17 and the second connecting shaft 16.

[0044] During the tape application process, the winding wheel 4 is driven to rotate by the force, which in turn drives the first guide wheel 18 to rotate. Since the inner wall of the connecting ring 17 abuts against the second connecting shaft 16 through the second friction part 21, neither the connecting ring 17 nor the buckle will rotate under the action of friction, forming a relative rotation with the first guide wheel 18. This allows the second guide rail 19 to move relative to the second linkage block 20. Therefore, under the action of the second guide rail 19, the buckle and the tooth 7 can be engaged or disengaged, ultimately achieving silent tape application or reverse rotation prevention of the correction tape. The hook 6 and the tooth 7 can be engaged and disengaged without pressing the tape application nozzle 5 to generate torque. The lever principle is used to achieve the engagement and disengagement of the hook 6 and the tooth 7, so there is no problem of insufficient pressing force, making it more convenient to use.

[0045] Variation Example

[0046] This embodiment is a variation of embodiment 2, referring to... Figures 11-13 In this variant, the connecting ring 17 and the hook 6 are located at the bottom of the first guide wheel 18 and are fixedly connected to the first guide wheel 18, eliminating the need for the second guide rail 19 and the second linkage block 20. This is mainly achieved through the material of the hook 6 itself. The hook 6 is made of PP "multi-folding rubber", which has the characteristics of not breaking after multiple deformations and good fluidity. Moreover, the sliding joint wall of the hook 6 is relatively thin. When the winding wheel 4 rotates forward, the hook 6 deforms and separates from the locking tooth 7, and the rebound force of the hook 6 after deformation is small. Therefore, it can achieve the effect of being quiet when rotating forward (lower than the existing conventional anti-reverse rotation sound). When the winding wheel 4 rotates in reverse, the hook 6 will press against the locking tooth 7, thereby achieving the effect of stopping the reverse rotation. The hook 6 and the locking tooth 7 are engaged and disengaged through the lever principle without pressing the sliding nozzle 5 to generate torque. Therefore, there is no problem of insufficient pressing force. The structure is simple and more convenient to use.

[0047] Example 3

[0048] The difference between this embodiment and Embodiment 1 is that the structures of the limiting component and the guide rail component are different, as shown in the following figure. Figures 14-16 In this embodiment, the limiting component includes a third mounting groove 22 disposed in the lower bottom 2, a hook 6 rotatably disposed in the third mounting groove 22, a third connecting shaft 23 disposed in the third mounting groove 22, and a locking tooth 7 disposed at the bottom end of the take-up reel 4. A column 27 is disposed in the third mounting groove 22, and one end of the hook 6 is rotatably sleeved on the column 27. Therefore, in this embodiment, the hook 6 does not need to be provided with a movable joint. In this embodiment, there are two hooks 6, which are respectively rotatably disposed in the third mounting groove 22 by the column 27. A limiting frame 30 is also provided in the second mounting groove 15. The shape of the limiting frame 30 is adapted to the shape of the hook 6, so that the hook 6 will rotate within the limiting range. The guide rail component includes a second guide wheel 24 sleeved on the third connecting shaft 23. A third guide rail 25 is disposed on the second guide wheel 24, and a third linkage block located in the third guide rail 25 is disposed on the hook 6. The inner wall of the second guide wheel 24 is provided with a third friction part 26 that abuts against the take-up wheel 4. The third friction part 26 is used to fix the position between the second guide wheel 24 and the take-up wheel 4. The locking tooth 7 is set at the bottom of the take-up wheel 4 through the connecting post 31. Specifically, the third friction part 26 abuts against the side wall of the connecting post 31.

[0049] During the tape-drawing process, the winding wheel 4 is driven to rotate by the force. Since the second guide wheel 24 abuts against the connecting column 31 through the third friction part 26, it will also drive the second guide wheel 24 to rotate. At the same time, the third guide rail 25 and the third linkage block rotate relative to each other. The third linkage block moves under the action of the third guide rail 25, which in turn drives the hook 6 to rotate around the column 27, realizing the engagement or disengagement of the hook 6 and the tooth 7. The engagement and disengagement of the hook 6 and the tooth 7 can be achieved by lever principle without pressing the tape nozzle 5 to generate torque. Therefore, there is no problem of insufficient pressing force, making it more convenient to use.

[0050] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
