Description

Technical Field

[0001] This invention relates to the field of stationery technology, specifically to a correction tape that can quickly switch between silent and sound modes. Background Technology

[0002] Correction tape is a common stationery item, primarily used to cover up writing or printing errors on paper documents, allowing for rewriting by covering the white correction material. Currently, common correction tape products on the market include silent flip-top correction tape, audible pull-out correction tape, audible push-button correction tape, and audible pen-shaped push-button correction tape. While these products generally meet the basic function of covering errors, they still have a number of obvious shortcomings in actual use, affecting user experience and applicable scenarios.

[0003] 1. Silent flip-top correction tape

[0004] These products feature a silent design, producing minimal noise during use, making them suitable for quiet environments such as libraries and examination rooms. However, their completely silent operation lacks the mechanical feedback of traditional correction tape, causing discomfort for some users who cannot confirm the effectiveness of the operation through sound. Therefore, they cannot fully meet the usage habits and psychological expectations of all consumers.

[0005] 2. Correction tape with sound removal function

[0006] These products emit a "click" sound through their gear structure, providing clear operational feedback. However, they also have significant drawbacks: First, the purely audible design makes them unsuitable for quiet environments, limiting their application scenarios; second, these products typically come with a separate protective cover to protect the nozzle, but this requires repeated insertion and removal, making operation cumbersome, and the cover is easily lost, exposing the nozzle to the outside environment, making it susceptible to contamination or damage.

[0007] 3. Sound-activated mouthpiece correction tape

[0008] This type of product controls the extension and retraction of the mouthpiece through a push-button mechanism, retaining an audible feedback mechanism. However, it has the following problems: First, it still cannot meet the requirement of silent operation, limiting its use in environments such as examination rooms and conference rooms; second, it requires continuous pressing of the top button to extend the mouthpiece, which is not convenient to operate and can easily lead to hand fatigue and reduced efficiency after prolonged use.

[0009] 4. Correction tape dispensed by pressing a pen-shaped nozzle.

[0010] These products resemble pens in appearance and offer a degree of portability, but their structure also has several shortcomings: First, the purely auditory design cannot achieve a silent mode, making it unsuitable for diverse usage environments; second, the pen-shaped structure typically has a long straight section at the front, causing the internal cartridge to become unusable before it is fully used, resulting in cartridge waste; third, the push-to-dispense mechanism is prone to jamming due to manufacturing tolerances or the entry of paper scraps, dust, and other impurities during use, leading to malfunctions in the extension / retraction function and severely impacting its lifespan and reliability.

[0011] In summary, existing correction tape products suffer from limitations such as single functional modes (only sound or only silent), structural design flaws, and restricted applicability, failing to simultaneously meet the needs of different user groups and diverse usage environments. Therefore, it is necessary to propose a new correction tape structure that enables one-click switching between silent and sound modes, thereby improving the product's versatility, convenience, and user experience. Summary of the Invention

[0012] To address this issue, the present invention provides a correction tape that can quickly switch between silent and audio modes, thereby resolving the aforementioned problems in the prior art.

[0013] To achieve the above objectives, the present invention provides the following technical solution:

[0014] According to a first aspect of the present invention, a correction tape capable of quickly switching between a silent mode and a sound mode includes a housing, a first drive wheel, a second drive wheel, a slide button, an anti-rotation arm, and a tape nozzle. The first drive wheel and the second drive wheel are both rotatably disposed within the housing and are connected to each other for transmission. A fixed cylinder is provided on one side of the first drive wheel, and a retraction wheel is provided on one side of the second drive wheel.

[0015] The anti-rotation arm is disposed within the housing and includes an upper arm, a lower arm, a rotating shaft, and a connecting column. One end of the upper arm and one end of the lower arm are both connected to the rotating shaft. The upper arm and the lower arm face the same direction, and a groove is provided between them. A backstop pawl is provided at the end of the upper arm away from the rotating shaft, and a ratchet gear is provided on the side of the second transmission wheel away from the recovery wheel. The backstop pawl engages with the tooth groove of the ratchet gear. A limiting platform is provided within the housing, and the end of the lower arm away from the rotating shaft abuts against the limiting platform. One end of the connecting column is connected to the rotating shaft, and the orientation of the connecting column is opposite to that of the upper arm. The rotating shaft is rotatably connected to the housing.

[0016] The housing is provided with a sliding hole, which is directly opposite the slot. The sliding button is slidably disposed in the sliding hole. The sliding button can slide into or out of the slot during the sliding process along the sliding hole.

[0017] One end of the nozzle is connected to the end of the connecting post opposite to the rotating shaft, and the other end of the nozzle extends outside the housing.

[0018] Furthermore, the sliding hole is an elongated hole, and a protrusion is provided in the middle of the sliding hole. There are two protrusions, which are respectively located at the top and bottom of the sliding hole.

[0019] One side of the slider is located on the outside of the housing, and the width of the side of the slider on the outside of the housing is greater than the width of the sliding hole; the other side of the slider is provided with two parallel spring pieces, which are slidably connected to the upper and lower edges of the sliding hole respectively, and each spring piece has a protruding edge at the end away from the slider, which is slidably connected to the inner wall of the housing.

[0020] Furthermore, it also includes a protective cover, which is disposed outside the housing, one side of which is hinged to the housing, and the protective cover is fastened to the spout.

[0021] Furthermore, the ratchet is coaxial with the second transmission wheel, the ratchet is an internal gear, and the ratchet is embedded in the second transmission wheel.

[0022] Furthermore, a positioning protrusion is provided at the end of the lower arm away from the rotation axis, and the positioning protrusion abuts against the limiting platform;

[0023] The end with the nozzle is provided with a connector, which is engaged with the end of the connecting post that is away from the rotating shaft.

[0024] Furthermore, both the first transmission wheel and the second transmission wheel are gears, which mesh with each other, and the diameter of the first transmission wheel is larger than the diameter of the second transmission wheel.

[0025] Furthermore, the housing includes a first housing and a second housing, which are detachably connected.

[0026] Furthermore, the inner side of the first housing is provided with a positioning post, a first positioning ring and a second positioning ring, and the positioning post, the first positioning ring and the second positioning ring are arranged sequentially along the length direction of the first housing;

[0027] The inner side of the second housing is provided with a first rotating shaft, a second rotating shaft, and a third rotating shaft, which are arranged sequentially along the length direction of the second housing; a sliding hole is provided on the second housing, and the sliding hole is located between the second rotating shaft and the third rotating shaft; a limiting platform is provided inside the second housing, and the sliding hole is located above the limiting platform;

[0028] The first rotating shaft, the second rotating shaft, and the third rotating shaft are respectively configured to correspond one-to-one with the positioning post, the first positioning ring, and the second positioning ring.

[0029] Furthermore, the first transmission wheel is rotatably mounted on the first rotating shaft, the second transmission wheel is rotatably mounted on the second rotating shaft, and the rotating shaft is rotatably mounted on the third rotating shaft.

[0030] Furthermore, a locking sleeve is provided on one side of the first transmission wheel, the locking sleeve is coaxially arranged with the first transmission wheel, and the fixing cylinder is snapped onto the locking sleeve.

[0031] This invention has the following advantages: When the sliding button is positioned outside the slot, pressing down on the nozzle for correction causes the nozzle to rotate the shaft. During rotation, the lower arm is deformed, causing the upper arm to move downwards away from the shaft, disengaging the anti-reverse pawl from the ratchet. During use, the second drive wheel rotates without contact between the anti-reverse pawl and the ratchet, resulting in a silent mode. After use, the lower arm automatically resets due to its own elasticity. When the sliding button is positioned inside the slot, pressing down on the nozzle for correction prevents movement of the upper arm, keeping the anti-reverse pawl locked in the ratchet's groove. During use, the second drive wheel rotates, continuously contacting the anti-reverse pawl and ratchet, producing a clicking sound – a audible mode. The silent and audible modes can be quickly switched by sliding the button, making operation simple, meeting various needs, and offering greater versatility and wider applicability.

[0048] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1

[0050] like Figures 1 to 13 As shown, a correction tape capable of quickly switching between silent and audible modes according to a first aspect embodiment of the present invention includes a housing, a first drive wheel 3, a second drive wheel 5, a slide button 7, an anti-rotation arm 8, and a nozzle 9. The housing is transparent. The first drive wheel 3 and the second drive wheel 5 are both rotatably disposed within the housing and are connected to each other for transmission. A fixing cylinder 4 is provided on one side of the first drive wheel 3, and the fixing cylinder 4 and the first drive wheel 3 are integrally formed. A recycling wheel 6 is provided on one side of the second drive wheel 5, and the recycling wheel 6 and the second drive wheel 5 are integrally formed.

[0051] An anti-rotation arm 8 is housed within the housing. The anti-rotation arm 8 includes an upper arm 21, a lower arm 24, a rotating shaft 22, and a connecting column 23. One end of the upper arm 21 and one end of the lower arm 24 are both connected to the rotating shaft 22. The upper arm 21 and lower arm 24 face the same direction, and a groove 27 is provided between them. A backstop pawl 26 is provided at the end of the upper arm 21 facing away from the rotating shaft 22. A ratchet 20 is provided on the side of the second transmission wheel 5 facing away from the recovery wheel 6. The lower arm 24 is engaged in the tooth groove of the ratchet gear 20; a limiting platform 18 is provided inside the housing, and the end of the lower arm 24 facing away from the rotating shaft 22 abuts against the limiting platform 18. The lower arm 24 is an elastic element, and the lower arm 24 can undergo slight deformation when compressed; one end of the connecting column 23 is connected to the rotating shaft 22. The upper arm 21, the lower arm 24 and the connecting column 23 are all perpendicular to the rotating shaft 22. The orientation of the connecting column 23 is opposite to the orientation of the upper arm 21. The rotating shaft 22 is rotatably connected to the housing.

[0052] The housing is provided with a sliding hole 17, which is directly opposite the slot 27. The sliding button 7 is slidably disposed in the sliding hole 17. The sliding button 7 can slide into or out of the slot 27 during the sliding process along the sliding hole 17.

[0053] One end of the nozzle 9 is connected to the end of the connecting post 23 that is away from the rotating shaft 22, and the other end of the nozzle 9 extends out of the housing; the belt core is set on the fixed cylinder 4, the belt core on the fixed cylinder 4 is an unused belt core, and the belt core is wound around the take-up wheel 6 after passing around the nozzle 9, and the take-up wheel 6 is used to take up the used belt core.

[0054] In this embodiment, it should be noted that, as Figure 7 As shown, the sliding hole 17 is an elongated hole, and there are two protrusions 29 in the middle of the sliding hole 17. The two protrusions 29 are respectively located at the top and bottom of the sliding hole 17.

[0055] One side of the slider 7 is located on the outside of the housing, and the width of the side of the slider 7 located on the outside of the housing is greater than the width of the sliding hole 17; the other side of the slider 7 is provided with two parallel spring pieces, which are slidably connected to the upper and lower edges of the sliding hole 17 respectively. Each spring piece has a protruding edge at the end away from the slider 7, and the protruding edge is slidably connected to the inner wall of the housing.

[0056] like Figure 3 As shown, when the slider 7 is located to the left of the protrusion 29, the inner side of the slider 7 is located inside the slot 27, and it is in the sound mode; when the slider 7 is located to the right of the protrusion 29, the inner side of the slider 7 is located outside the slot 27, and it is in the silent mode. By setting the protrusion 29, the slider 7 can be prevented from sliding automatically during use, so that the entire correction tape can be stably in the sound mode or the silent mode when there is no manual pushing. At the same time, when the slider 7 is pushed past the protrusion 29, a clear tactile sensation is formed to determine whether the slider has slid into place.

[0057] The technical effect achieved in this embodiment is as follows: When the sliding button 7 is located outside the slot 27, and the nozzle 9 is pressed down for correction, the nozzle 9 drives the rotating shaft 22 to rotate. During the rotation of the rotating shaft 22, the lower arm 24 is pressed down, causing it to deform to a certain extent, and the end of the upper arm 21 that is away from the rotating shaft 22 moves down, so that the anti-reverse pawl 26 is disengaged from the ratchet 20. During use, when the second transmission wheel 5 rotates, the anti-reverse pawl 26 and the ratchet 20 do not contact each other and no sound is made, which is a silent mode. After use, the anti-rotation arm 8 can automatically return to its original position under the action of the elastic force of the lower arm 24. When the sliding button 7 is located inside the slot 27, and the nozzle 9 is pressed down for correction, the upper arm 21 is blocked by the sliding button 7, so the upper arm 21 has no contact with the ratchet 20. When the belt moves, the anti-reverse pawl 26 remains locked in the groove of the ratchet 20. During use, as the second transmission wheel 5 rotates, the anti-reverse pawl 26 and the ratchet 20 are in continuous contact, producing a clicking sound, which is the audible mode. When the belt is not in use and is not under stress, the belt nozzle 9 is reset due to the elasticity of the lower arm 24 of the anti-rotation arm 8. The grooves of the anti-reverse pawl 26 and the ratchet 20 are also reset, and the grooves of the anti-reverse pawl 26 and the ratchet 20 have a clamping force, preventing the belt core from loosening due to external force. During use, the belt nozzle 9 can swing up and down within the range of +15° to -15°. When in use, the silent mode and the audible mode can be quickly switched by sliding the slider 7. The operation is simple and can meet various needs, making it more versatile and applicable to a wider range of situations.

[0061] In this embodiment, it should be noted that the protective cover 10 has a groove on the side facing the mouth 9, and the part of the housing with the protective cover 10 is an arc-shaped surface, so that the protective cover 10 can be opened and closed with a certain elasticity, making it convenient for the protective cover 10 to open and close.

[0062] The technical effect achieved by this embodiment is that by setting the protective cover 10, the mouthpiece 9 can be protected. At the same time, the protective cover 10 is hinged to the shell, so there is no risk of loss.

The ratchet 20 and the second transmission wheel 5 are an integral structure, making the overall structure more compact and effectively reducing the volume.

[0066] The lower arm 24 has a positioning protrusion 25 at the end opposite to the rotation shaft 22, and the top of the limiting platform 18 is L-shaped, with the positioning protrusion 25 abutting against the top of the limiting platform 18.

[0067] One end of the nozzle 9 is provided with a connector 28. The connector 28 and the nozzle 9 are an integral structure. The connector 28 is a quick plug. The connector 28 is snapped into the end of the connecting post 23 that is away from the rotating shaft 22.

[0068] In this embodiment, it should be noted that both the first transmission wheel 3 and the second transmission wheel 5 are gears, the first transmission wheel 3 and the second transmission wheel 5 mesh with each other, and the diameter of the first transmission wheel 3 is larger than the diameter of the second transmission wheel 5.

[0069] The technical effect achieved by this embodiment is that the use of gear transmission results in more stable transmission performance, which can effectively ensure stable use.

[0075] The first rotating shaft 14, the second rotating shaft 15, and the third rotating shaft 16 are respectively set to the positioning post 11, the first positioning ring 12, and the second positioning ring 13. The first rotating shaft 14, the second rotating shaft 15, and the third rotating shaft 16 are all cylindrical. The positioning post 11 can be inserted into the end of the first rotating shaft 14, and the end of the third rotating shaft 16 can be inserted into the second positioning ring 13.
