Description

Technical Field

[0001] This utility model relates to the field of correction tape technology, specifically to a telescopic pressing head for 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. It was invented by SEED Corporation of Japan in 1989. The main components of correction tape include AS, PS, resin, and titanium dioxide. The structure includes upper and lower covers, large and small gears, 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 cover seat; the connecting body has positioning pins; the middle and rear parts of the connecting body have open slots, the bottom of which are the pinion and large gear shaft holes, respectively; the large and small gears are respectively fitted into the large and small shaft holes of the connecting body, and they mesh together to evenly feed the correction tape.

[0003] In traditional correction tapes, the tape exit tip is exposed. During daily use, this tip is prone to friction and collisions with other objects, causing deformation and breakage, which affects the normal tape delivery and may even render the tape unusable. Furthermore, correction tape exposed for extended periods easily accumulates dust and debris. These impurities entering the tape increase the likelihood of jamming and affect its smoothness of use. Utility Model Content

[0004] The purpose of this invention is to provide a corrective tape retractable press head to address the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable pressing head for correcting tape, comprising: a tape outlet head, both ends of which are provided with protective plates, a slide plate connected to one side of the tape outlet head, a first connecting plate provided on the top of the slide plate, a rotating shaft connected to both ends of the first connecting plate, a second connecting plate connected to the other end of the rotating shaft, a first sliding groove provided inside the second connecting plate, a pulley slidably connected inside the first sliding groove, and a third connecting plate provided at the bottom of the pulley.

[0006] Furthermore, one side of the third connecting plate is connected to a rotating shaft and a pulley, and the other rotating shaft is connected to the second connecting plate and the telescopic bracket. The telescopic bracket has a second sliding groove inside.

[0007] Furthermore, the other end of the third connecting plate is connected to a first rotating rod, and the bottom of the first rotating rod is connected to a turntable.

[0008] Furthermore, the middle end of the first rotating rod is connected to the lower housing, and the top of the lower housing is provided with the upper housing.

[0009] Furthermore, the bottom of the upper housing is provided with several limiting holes, the top of the lower housing is connected with limiting protrusions, and the limiting holes are fitted with limiting protrusions.

[0010] Furthermore, a second rotating rod is connected inside the lower housing, and a first gear disk is connected to the top of the second rotating rod, with the first gear disk meshing with the second gear disk.

[0011] In the above technical solution, the beneficial effects of the correction tape telescopic pressing head provided by this utility model are as follows:

[0012] This invention utilizes a first rotating rod to rotate a third connecting plate around it. This causes a pulley to slide within a first groove in the second connecting plate, resulting in the second connecting plate rotating. This, in turn, causes a sliding plate connected to the other end of the first connecting plate to extend and retract. The cooperation of these components minimizes friction and resistance during movement, ensuring smooth operation and stable operation of the correction tape during extension, retraction, and tape dispensing. This prevents damage caused by the correction tape head being exposed due to shaking or deviation.

[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figures 1-4 A retractable pressing head for correction tape includes: a tape outlet 3, with protective plates 4 at both ends of the tape outlet 3, a slide plate 12 connected to one side of the tape outlet 3, a first connecting plate 15 at the top of the slide plate 12, a rotating shaft 16 connected to both ends of the first connecting plate 15, a second connecting plate 18 connected to the other end of the rotating shaft 16, a first groove 19 inside the second connecting plate 18, a pulley 20 slidably connected inside the first groove 19, a third connecting plate 17 at the bottom of the pulley 20, a rotating shaft 16 and a pulley 20 passing through one side of the third connecting plate 17, and a second rotating shaft 16 passing through the second connecting plate 18 and a telescopic bracket 13, a second groove 14 inside the telescopic bracket 13, a first rotating rod 6 connected to the other end of the third connecting plate 17, and a turntable 5 connected to the bottom of the first rotating rod 6.

[0024] In a further embodiment of this utility model, the protective plate 4 can prevent the tape head 3 from being damaged or contaminated with dust when not in use, and at the same time can reduce the breakage of the paper tape at the tape head 3 caused by other factors. By rotating the turntable 5, the rotation of the turntable 5 causes the first rotating rod 6 connected to the turntable 5 to rotate, and the rotation of the first rotating rod 6 causes the third connecting plate 17 to rotate around the first rotating rod 6. The pulley 20 connected to the other end of the third connecting plate 17 can slide in the first sliding groove 19 opened inside the second connecting plate 18. The pulley 20 slides from one end to the other end inside the first sliding groove 19, thereby causing the second connecting plate 18 to rotate around the rotating shaft 16 connected to the telescopic bracket 13, and the first connecting plate 15 connected to it at the other end rotates around another rotating shaft 16, thereby driving the rotating shaft 16 connected to the slide plate 12 at the other end of the first connecting plate 15 to rotate synchronously, so that the slide plate 12 slides in the second sliding groove 14 opened inside the telescopic bracket 13, so as to adjust the position of the tape head 3.

[0025] Furthermore, the middle end of the first rotating rod 6 is connected to the lower housing 2, the top of the lower housing 2 is provided with the upper housing 1, the bottom of the upper housing 1 is provided with several limiting holes 8, the top of the lower housing 2 is connected to the limiting protrusion 7, and the limiting hole 8 is fitted with the limiting protrusion 7. The lower housing 2 is connected to the inside of the second rotating rod 10, the top of the second rotating rod 10 is connected to the first gear disk 9, and the first gear disk 9 meshes with the second gear disk 11.

[0026] In a further embodiment of this utility model, by aligning the limiting hole 8 at the bottom of the upper housing 1 with the limiting protrusion 7 connected to the top of the lower housing 2, the limiting protrusion 7 is fitted into the interior of the limiting hole 8, thereby facilitating the opening of the correction tape housing. This split design facilitates the installation, maintenance, and replacement of internal parts. The upper housing 1 and the lower housing 2 together constitute the main structure of the correction tape, providing reliable protection for its internal components. The first gear disk 9 is the unused correction tape wrapping area, and the second gear disk 11 is the used correction tape wrapping area. By rotating the first gear disk 9 under the action of the second rotating rod 10, the meshing second gear disk 11 can also rotate synchronously, thereby achieving smooth delivery and retraction of the correction tape.

[0027] In this application, the protective plate 4 prevents the tape head 3 from being damaged or contaminated with dust when not in use, and also reduces the risk of the tape at the tape head 3 breaking due to other factors. By rotating the turntable 5, the first rotating rod 6 connected to the turntable 5 rotates, and the rotation of the first rotating rod 6 causes the third connecting plate 17 to rotate around the first rotating rod 6. The pulley 20 connected to the other end of the third connecting plate 17 can slide in the first groove 19 opened inside the second connecting plate 18. The pulley 20 slides from one end to the other end inside the first groove 19, thereby causing the second connecting plate 18 to rotate around the rotating shaft 16 connected to the telescopic bracket 13. The first connecting plate 15 connected to it at the other end rotates around another rotating shaft 16, thereby driving the rotating shaft 16 connected to the slide plate 12 at the other end of the first connecting plate 15 to rotate synchronously, so that the slide plate 12 slides inside the second groove 14 opened inside the telescopic bracket 13, so as to adjust the position of the tape head 3.

[0028] The foregoing has only described certain exemplary embodiments of this utility model by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of this utility model. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of this utility model.
