Description

Technical Field

[0001] This utility model relates to the field of correction tape technology, and in particular to a rotating core-ejection correction tape. Background Technology

[0002] Correction tape is a common stationery item used by students to correct mistakes. To address the issue of protecting the tape tip, retractable refill correction tape has emerged on the market. For example, the push-button type correction tape disclosed in Chinese Utility Model Patent 200420115271.3 has the same structure and principle as a push-button ballpoint pen. When the front part 6 and the rear part 5 slide downwards, they rotate downwards, causing the correction tape refill to wobble significantly within the casing, resulting in a poor user experience—a common problem with push-button structures. Currently, most retractable refill correction tapes on the market use this push-button structure, limiting user choices. Therefore, there is a need to develop other retractable refill correction tape structures to provide users with more options. Utility Model Content

[0003] This invention provides a correction belt with a rotating core-out method to address the above problems.

[0004] The technical solution used by this utility model to solve the above problems is: a rotating core-exit correction belt, comprising: The outer shell has a hollow tubular structure with a first opening at the lower end, and the upper side wall of the outer shell has a circumferentially extending groove. A guide component is connected inside the housing. The guide component is provided with an axially extending guide tube, and the side wall of the guide tube is provided with an axially extending guide groove. The driving component is located inside the housing and connected to the upper end of the guide component, and rotates circumferentially along the axis of the housing. The outer wall of the driving component is provided with a lever that extends out of the housing through a sliding groove. The driving component is provided with an action part, which is located on the outer periphery of the guide tube and has a driving inclined surface. A transmission rod is axially slidably connected within a guide tube, extending beyond the lower end of the guide tube. A protrusion is provided on the upper sidewall of the transmission rod, slidably connected within a guide groove. A transmission block protruding beyond the sidewall of the guide tube is provided on the protrusion, and a mating inclined surface is provided on the transmission block to contact the driving inclined surface. After the driving component rotates, the actuating part pushes the transmission block downwards through the engagement of the driving inclined surface and the mating inclined surface. A limiting recess is provided at the lower end of the actuating part; after the transmission block descends, it engages within the limiting recess, restricting the upward movement of the transmission rod. The replacement core is located inside the housing and connected to the lower end of the transmission rod, sliding up and down with the transmission rod to extend or retract into the housing.

[0005] This utility model relates to a rotary correction tape core extender. A rotating lever rotates the drive unit, which in turn rotates the drive ramp and mating ramp to push the transmission block downwards. Once the transmission block reaches the lower end of the action section, it engages with the limiting recess, restricting the upward movement of the transmission rod. Reversing the drive unit disengages the transmission block from the limiting recess, allowing it to move upwards. The transmission rod slides axially and is circumferentially limited within the guide tube via a protrusion and guide groove. With this structure, the core extender is moved up and down by the rotating drive unit, preventing circumferential rotation. Compared to existing technologies, this design offers greater stability during the up-and-down movement of the correction tape core, effectively reducing wobbling within the casing and providing a better user experience.

[0006] Preferably, the transmission rod is provided with an elastic restoring element, which is a spring, to maintain its upward trend. A rib protrudes from the lower end of the inner wall of the guide tube. The spring is located inside the guide tube and sleeved on the transmission rod, with its upper end abutting against the lower end of the protrusion and its lower end abutting against the upper end of the rib. The elastic restoring element allows the transmission rod to quickly rebound upwards.

[0007] Preferably, the actuating part includes two symmetrical arc-shaped plates, with driving inclined surfaces on both sides of the arc-shaped plates, and the limiting recess is located at the lower end of the arc-shaped plates; the arcs formed by the cross-sections of the two arc-shaped plates lie on the circumference of the same circle. The two arc-shaped plates form a circular tube shape, and the driving inclined surfaces on both sides of the arc-shaped plates are connected to the driving inclined surfaces of the other arc-shaped plate. Two symmetrical transmission blocks are provided on both sides of the transmission rod, and the two transmission blocks respectively cooperate with the driving inclined surfaces of the two arc-shaped plates, so that the up and down sliding of the transmission rod is more stable.

[0008] Preferably, the top of the core is provided with a connecting ball, and the lower end of the transmission rod is provided with a connecting claw that engages with the connecting ball.

[0009] Preferably, the upper end of the outer shell is provided with a second opening, and the upper end of the transmission rod is provided with a decorative part, which slides up and down with the transmission rod to extend out or retract into the outer shell. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 5 As shown, a rotating core-exit correction belt includes a housing 1, a guide 2, a drive 3, a transmission rod 4, and a replacement core 5.

[0018] The outer shell 1 has a hollow tubular structure with a first opening 101 at the lower end and a circumferentially extending groove 11 on the upper side wall of the outer shell 1.

[0019] The guide component 2 is fixedly connected inside the housing 1. The guide component 2 has an axially extending guide tube 21 at its center and an axially extending guide groove 210 on its side wall.

[0020] The driving component 3 is located inside the housing 1 and connected to the upper end of the guide component 2, and rotates circumferentially along the axis of the housing 1. The outer wall of the driving component 3 is provided with a lever 8 that extends out of the housing 1 through a slide groove 11. The driving component 3 is provided with an action part, which is located on the outer periphery of the guide tube 21 and has a driving inclined surface 310.

[0021] The transmission rod 4 is axially slidably connected inside the guide tube 21. The transmission rod 4 can extend out of the lower end of the guide tube 21. The upper side wall of the transmission rod 4 is provided with a protrusion 41. The protrusion 41 is slidably connected in the guide groove 210. The upper end of the guide groove 210 is open to facilitate the insertion of the protrusion 41 into the guide groove 210. The protrusion 41 is provided with a transmission block 42 protruding outside the side wall of the guide tube 21. The transmission block 42 is provided with a mating inclined surface 420 that contacts the driving inclined surface 310.

[0022] After the driving component 3 rotates, the actuating part pushes the transmission block 42 downward through the engagement of the driving inclined surface 310 and the mating inclined surface 420. The actuating part includes two symmetrical arc-shaped plates 31. The driving inclined surface 310 is located on both sides of the arc-shaped plate 31. The lower end of the arc-shaped plate 31 is provided with a limiting recess 311. After the transmission block 42 moves downward, it is engaged in the limiting recess 311, restricting the upward movement of the transmission rod 4. The arcs formed by the cross-sections of the two arc-shaped plates 31 are on the circumference of the same circle. The two arc-shaped plates 31 form a circular tube shape. The driving inclined surfaces 310 on both sides of the arc-shaped plate 31 are connected to the driving inclined surface 310 of the other arc-shaped plate 31. Two symmetrical transmission blocks 42 are provided on both sides of the transmission rod 4. The two transmission blocks 42 respectively engage with the driving inclined surfaces 310 of the two arc-shaped plates 31, so that the up and down sliding of the transmission rod 4 is more stable.

[0023] The replacement core 5 is located inside the outer casing 1 and connected to the lower end of the transmission rod 4, and slides up and down with the transmission rod 4 to extend or retract into the outer casing 1.

[0024] The transmission rod 4 is equipped with an elastic reset element, which keeps it trending upward. The elastic reset element is a spring 6. A rib 211 protrudes from the lower end of the inner wall of the guide tube 21. The spring 6 is located inside the guide tube 21 and is sleeved on the transmission rod 4. The upper end of the spring 6 abuts against the lower end of the protrusion 41, and the lower end of the spring 6 abuts against the upper end of the rib 211. The elastic reset element allows the transmission rod 4 to quickly spring back upward.

[0025] The top of the core 5 is provided with a connecting ball 51, and the lower end of the transmission rod 4 is provided with a connecting claw 43 that engages with the connecting ball 51.

[0026] The upper end of the outer shell 1 is provided with a second opening 102, and the upper end of the transmission rod 4 is provided with a decorative part 7. The decorative part 7 slides up and down with the transmission rod 4 to extend or retract into the outer shell 1.

[0027] This utility model relates to a rotary correction tape. Rotating the lever 8 causes the drive component 3 to rotate. After rotation, the drive component 3 drives the inclined surface 310 and the mating inclined surface 420 to push the transmission block 42 downwards. Once the transmission block 42 reaches the lower end of the action part, it engages within the limiting recess 311, restricting the upward movement of the transmission rod 4. Reversing the lever 8 causes the drive component 3 to reverse, disengaging the transmission block 42 from the limiting recess 311. Under the action of the spring 6, the transmission rod 4 moves upwards. Rotating the drive component 3 pushes the transmission rod 4 to slide up and down, thus extending and retracting the replacement core 5. The transmission rod 4 is axially slidable and circumferentially limited within the guide tube 21 through the engagement of the protrusion 41 and the guide groove 210. The up-and-down sliding of the transmission rod 4 does not involve circumferential rotation, resulting in more stable up-and-down sliding and effectively reducing the shaking of the correction tape replacement core within the housing, thus improving the user experience.
