Description

Technical Field

[0001] This utility model relates to the field of correction tape technology, specifically, to a correction tape. Background Technology

[0002] Correction tape, a widely used stationery item, originated from the improvement and upgrading of traditional methods of correcting writing errors. In the past, people often used correction fluid or blades to correct writing errors, but these methods had many inconveniences and drawbacks. Correction fluid was easy to apply unevenly and could leave obvious marks after drying, affecting the overall appearance of the text; while using a blade to scrape off incorrect text could easily damage the paper or even cut fingers, creating safety hazards. To solve these problems, correction tape was developed. Correction tape, through its internal core and roller mechanism, can evenly apply white correction tape material to the incorrect text, quickly covering and correcting errors. Compared with traditional correction methods, correction tape has advantages such as ease of use, good correction effect, and minimal damage to paper.

[0003] While existing correction tape technology has enabled rapid correction of writing errors, it still has some shortcomings in terms of ease of use and durability. The sliding head, as a key component in the operation of correction tape, is easily damaged by accidental collisions or friction when not in use. This not only affects the normal use of the correction tape but may also shorten its overall lifespan. In addition, existing correction tapes lack effective anti-reverse mechanisms in the design of the take-up and feed rollers. If the user makes a mistake during operation, such as using excessive force or improper operation, the take-up roller may reverse, causing the film to roll backward. This will not only damage the corrected text but also cause unnecessary trouble and inconvenience to the user. Utility Model Content

[0004] The purpose of this invention is to provide a correction tape that addresses the problem that the sliding head, as a key component in the operation of the correction tape, is easily damaged by accidental collisions or friction when not in use. This not only affects the normal use of the correction tape but may also shorten its overall lifespan. Furthermore, existing correction tapes lack an effective anti-reverse mechanism in the design of the take-up and feed rollers. If the user makes a mistake during operation, such as using excessive force or improper operation, the take-up roller may reverse, causing the film roll to turn backward. This not only damages the corrected text but also causes unnecessary trouble and inconvenience to the user.

[0005] This utility model provides the following technical solution: a correction tape, including a main body mechanism, the main body mechanism including an inner rod, a sliding head being engaged at the end of the inner rod, a take-up pulley being rotatably connected to the end of the inner rod away from the sliding head, a feed pulley being rotatably sleeved on the inner rod below the take-up pulley, a protective mechanism for protecting the inner rod being provided on the outer wall of the main body mechanism, and a backstop mechanism being provided between the take-up pulley and the feed pulley at the end of the inner rod away from the sliding head.

[0006] As a preferred embodiment of the above technical solution, the protective mechanism includes a protective sleeve that is slidably sleeved on the outer wall of the inner rod, and two half-protective sleeves are slidably sleeved at the end of the protective sleeve, and the two half-protective sleeves are spliced ​​together to form a tube head body.

[0007] As a preferred embodiment of the above technical solution, the outer wall of the protective sleeve is symmetrically provided with limiting holes, and two sets of limiting blocks that engage with the limiting holes are symmetrically fixedly connected to the side of the tube head body near the protective sleeve. The position of the tube head body is directly opposite the position of the take-up pulley.

[0008] As a preferred embodiment of the above technical solution, the anti-reverse mechanism includes a ratchet tooth located at the end of the inner rod away from the sliding head and below the take-up wheel. The bottom end of the take-up wheel is fixedly connected to a limiting head, and the limiting head is rotatably sleeved inside the feed wheel. The bottom end of the take-up wheel is fixedly connected to two locking blocks that engage with the ratchet tooth.

[0009] As a preferred embodiment of the above technical solution, the surface of the protective sleeve is provided with honeycomb-shaped anti-slip grooves.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] In this utility model, by setting up a protective mechanism and an anti-reverse mechanism, the sliding protective sleeve can protect the sliding head during use, preventing damage to the sliding head when not in use, thus affecting normal use.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a correction tape, including a main body mechanism 1, the main body mechanism 1 including an inner rod 11, a sliding head 12 is engaged at the end of the inner rod 11, a take-up wheel 13 is rotatably connected to the end of the inner rod 11 away from the sliding head 12, a feed wheel 14 is rotatably sleeved on the inner rod 11 below the take-up wheel 13, a protective mechanism 2 is provided on the outer wall of the main body mechanism 1 to protect the inner rod 11, and a backstop mechanism 3 is provided at the end of the inner rod 11 away from the sliding head 12 between the take-up wheel 13 and the feed wheel 14.

[0020] Using the above technical solution, the inner rod 11, as the core component, not only supports the sliding head 12 to enable precise user control, but also cleverly connects the take-up roller 13 and the feed roller 14 through the rotating connection at both ends, ensuring the smooth operation of the correction tape during use. The protective mechanism 2 provides all-round protection for the inner rod 11, effectively preventing damage caused by external collisions or friction, and extending the service life of the correction tape. At the same time, the protective mechanism 2 also enhances the appearance and improves the feel, allowing users to have a more comfortable and pleasant experience during use. The anti-reverse mechanism 3 effectively prevents the take-up roller 13 from rotating in reverse when not needed, thereby avoiding accidental loosening or falling off of the correction tape. This not only enhances the stability and reliability of the correction tape, but also allows users to focus more on the text content during correction without frequently adjusting the state of the correction tape.

[0021] like Figure 2 and Figure 3As shown, the protective mechanism 2 includes a protective sleeve 21 that is slidably sleeved on the outer wall of the inner rod 11. Two half-protective sleeves 221 are slidably sleeved at the end of the protective sleeve 21, and the two half-protective sleeves 221 are spliced ​​together to form a tube head body 22. Limiting holes 23 are symmetrically opened on the outer wall of the protective sleeve 21. Two sets of limiting blocks 24 that are engaged with the limiting holes 23 are symmetrically fixedly connected on the side of the tube head body 22 near the protective sleeve 21. The position of the tube head body 22 is directly opposite the position of the take-up pulley 13.

[0022] Using the above technical solution, the protective sleeve 21, as the main body of the protective mechanism 2, is sleeved on the outer wall of the inner rod 11, providing an effective protective barrier for the inner rod 11 and its various components. This design not only prevents the inner rod 11 from being worn and impacted due to direct exposure, but also ensures the overall stability of the correction tape structure. The innovative design of the two half-protective sleeves 221 allows the tube head body 22 to be flexibly spliced ​​together and tightly sleeved on the end of the protective sleeve 21. This detachable and splicable structure not only facilitates cleaning and maintenance for users, but also saves more space when carrying and storing the correction tape. The clever cooperation between the limiting hole 23 and the limiting block 24 ensures the stable position of the tube head body 22 on the protective sleeve 21. Users can easily slide the tube head body 22 to a suitable position as needed, and fix the tube head body 22 by engaging the limiting block 24 with the limiting hole 23. This not only improves the convenience of using the correction tape, but also ensures the stability and accuracy of the take-up wheel 13 during operation.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the anti-reverse mechanism 3 includes a ratchet 31 located on the inner rod 11 at the end away from the sliding head 12 and below the take-up pulley 13. The bottom end of the take-up pulley 13 is fixedly connected to a limiting head 33, and the limiting head 33 is rotatably sleeved inside the feed pulley 14. The bottom end of the take-up pulley 13 is fixedly connected to two locking blocks 32 that engage with the ratchet 31. The surface of the protective sleeve 21 is provided with honeycomb-shaped anti-slip grooves.

[0024] By adopting the above technical solution, the interlocking action between the ratchet 31 and the locking block 32 can effectively prevent the take-up pulley 13 from rotating in reverse, thereby ensuring the stable tightening and locking of the belt. In addition, the limiting head 33 is rotatably sleeved inside the feed pulley 14, which not only enhances the structural stability of the take-up pulley 13, but also makes the operation of the entire mechanism smoother and more stable. The honeycomb anti-slip grooves on the surface of the protective sleeve 21 further improve the user's feel and safety during operation. These anti-slip grooves can increase the friction between the fingers and the surface of the sleeve, effectively preventing accidents caused by hand slippage during operation, allowing the user to more accurately control the movement of the inner rod 11, thereby achieving precise adjustment of the belt.

[0025] Working principle: During use, the user can move the sliding head 12 on the paper by pressing it, thereby moving the roll film and covering the correction tape film on the paper. During this process, both the take-up roller 13 and the feed roller 14 will rotate. A backstop mechanism 3 is provided between the take-up roller 13 and the feed roller 14. When the feed roller 14 rotates, it will drive the roll film to rotate. Through the mutual engagement between the roll film and the take-up roller 13, the take-up roller 13 will rotate. After the take-up roller 13 rotates, it will drive the lower locking block 32 to rotate, thereby engaging with the ratchet 31. When the take-up pulley 13 wants to reverse, the engagement of the locking block 32 and the ratchet 31 prevents it from reversing and causing the film to fall off. In daily use, the sliding head 12 is often damaged due to bumps or impacts. Therefore, when not in use, the user can slide the protective sleeve 21 to cover the sliding head 12. At this time, the limiting hole 23 engages with the limiting block 24 on the outer wall of the tube head body 22. When needed, press the limiting block 24 to compress it and then move the protective sleeve 21, at which point the sliding head 12 is exposed and can be used.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
