Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] This utility model provides a data cable rewinder, including a housing 1. A winding mechanism 3 is movably mounted on the housing 1 via a main shaft 2. A data cable 4 is fixedly connected to the winding mechanism 3. The winding mechanism 3 includes a rotating disk 5 and a swing arm 6. The rotating disk 5 is elastically connected to the main shaft 2 via a spring 7. The rotating disk 5 has a first guide groove 8, a second guide groove 9, a return guide groove 10, and a self-locking island 11. The self-locking island 11 has a notch 12. One end of the swing arm 6 is movably connected to the housing 1 via a first shaft 13, and the other end of the swing arm 6 has a guide block 14. A guide protrusion 15 is provided in the second guide groove 9 and located at the return guide groove 10. An offset protrusion 16 is provided on the opposite side of the notch 12 on the rotating disk 5. A return protrusion 17 is provided on the self-locking island 11. A sound block 19 is movably mounted on the housing 1 via a second shaft 18. The sound block 19 has a protrusion 20. A spring piece 21 is fixedly mounted on the housing 1, and the spring piece 21 is elastically connected to the sound block 19. The rotating disk 5 has a protruding ring 22 with a notch 23. The rotating disk 5 has a mounting base 24, and the spring 7 is disposed in the mounting base 24. A cover plate 25 is fixedly mounted on the mounting base 24. The rotating disk 5 has a first sliding hole 26, which is movably connected to the main shaft 2. The cover plate 25 has a second sliding hole 27. The housing 1 has a frustum 28, and the second sliding hole 27 is movably connected to the frustum 28.

[0025] Through the above technical solution, the housing 1 of this utility model is movably mounted with a winding mechanism 3 via a main shaft 2. The winding mechanism 3 is fixedly connected to the data cable 4. The winding mechanism 3 includes a rotating disk 5 and a swing arm 6. In use, when the user pulls the data cable 4, the rotating disk 5 rotates, and the spring 7 stores energy. The guide block 14 of the swing arm 6 slides relative to the first guide groove 8. When the user releases the data cable 4, the spring 7 drives the rotating disk 5 to reverse, and the guide block 14 slides relative to the first guide groove 8. When the guide block 14 slides relative to the self-locking island 11, the guide block 14 automatically slides the notch 12 of the self-locking island 11, thereby locking the rotating disk 5 and fixing the data cable 4 at the pulled-out length. In this invention, when the data cable 4 needs to be wound up, the data cable 4 is pulled to disengage the guide block 14 from the notch 12 of the self-locking island 11, and then the data cable 4 is released. At this time, the guide block 14 enters the second guide groove 9, and the spring 7 drives the rotating disk 5 to continue to reverse. The guide block 14 slides relative to the data cable 4 in the second guide groove 9 until the data cable 4 is wound up. In the next pull-out operation, the guide block 14 enters the first guide groove 8 through the return guide groove 10. This invention completes the winding and self-locking length functions of the data cable 4 by setting multiple guide grooves on the rotating disk 5 and cooperating with the guide block 14 of the swing arm 6. The multiple guide grooves of the rotating disk 5 are completed by one-time injection molding, reducing the number of components and reducing production costs.

[0026] Example 2:

[0027] In this embodiment, a winding mechanism 3 is movably mounted inside the housing 1 via a main shaft 2. The winding mechanism 3 is fixedly connected to a data cable 4, one end of which extends to the outside through an outlet on the housing 1. The winding mechanism 3 consists of a rotating disk 5 and a swing arm 6. The rotating disk 5 is elastically connected to the main shaft 2 via a spring 7. When the user pulls the data cable 4, the rotating disk 5 rotates accordingly, causing the spring 7 to store energy. The rotating disk 5 is provided with a first guide groove 8, a second guide groove 9, a return guide groove 10, and a self-locking island 11. These structures are manufactured using a one-time injection molding process, reducing the number of components. The self-locking island 11 has a notch 12 for locking the rotating disk 5 at a specific position.

[0028] One end of the swing arm 6 is movably connected to the housing 1 via the first shaft 13, allowing it to swing around the first shaft 13. The other end of the swing arm 6 is equipped with a guide block 14, which engages with various guide slots on the rotating disk 5. Initially, the guide block 14 is located at the starting position of the first guide slot 8. When the user pulls the data cable 4, the rotating disk 5 rotates clockwise, and the guide block 14 slides relative to it within the first guide slot 8. At this time, the spring 7 is wound, storing elastic potential energy. When the user releases the data cable 4, the spring 7 releases energy, causing the rotating disk 5 to rotate counterclockwise.

[0029] During rotation, guide block 14 continues to slide within the first guide groove 8. When the rotating disk 5 rotates to a specific angle, i.e., when guide block 14 approaches the self-locking island 11, guide block 14 slides into the recess 12 of the self-locking island 11. At this time, the rotating disk 5 is locked, and the data cable 4 remains at its extended length. This locking state prevents the data cable 4 from automatically rewinding, making it convenient for the user. When it is necessary to retract the data cable 4, the user only needs to gently pull the data cable 4 again to disengage guide block 14 from the recess 12 of the self-locking island 11. After releasing the data cable 4, the spring 7 continues to drive the rotating disk 5 to rotate, at which point guide block 14 enters the second guide groove 9.

[0030] Within the second guide groove 9, the guide block 14 guides the rotating disk 5 to continue rotating until the data cable 4 is fully wound up. After winding, the guide block 14 is located within the second guide groove 9. When the data cable 4 is pulled again, the rotating disk 5 begins to rotate clockwise, and the guide block 14 re-enters the first guide groove 8 via the return guide groove 10, preparing for the next winding and unwinding operation. The design of the return guide groove 10 ensures the continuity of the usage cycle.

[0031] This embodiment achieves controllable winding and length locking of the data cable 4 through the cooperation of multiple guide grooves on the rotating disk 5 and the guide block 14 of the swing arm 6. The entire mechanism has a simple structure and few components, reducing production costs. The rotating disk 5 adopts a one-piece molding design, avoiding complex assembly processes. The spring mechanism 7 provides stable winding power, ensuring smooth winding and unwinding of the data cable 4. The self-locking island 11 allows the data cable 4 to be fixed at any desired length position, improving ease of use.

[0032] Example 3:

[0033] In this embodiment, a winding mechanism 3 is movably mounted on the housing 1 via a main shaft 2, and a data cable 4 is fixedly connected to the winding mechanism 3. The winding mechanism 3 includes a rotating disk 5 and a swing arm 6. The rotating disk 5 is elastically connected to the main shaft 2 via a spring 7. The rotating disk 5 is provided with a first guide groove 8, a second guide groove 9, a return guide groove 10, and a self-locking island 11. The self-locking island 11 is provided with a notch 12. One end of the swing arm 6 is movably connected to the housing 1 via a first shaft 13, and the other end of the swing arm 6 is provided with a guide block 14. A guide protrusion 15 is provided in the second guide groove 9 and located at the return guide groove 10.

[0034] During use, when the user pulls the data cable 4, the rotating disk 5 rotates accordingly, the spring 7 stores energy, and the guide block 14 of the swing arm 6 slides within the first guide groove 8. When the user releases the data cable 4, the spring 7 releases energy, causing the rotating disk 5 to rotate in the opposite direction, and the guide block 14 continues to slide within the first guide groove 8. When the guide block 14 slides to the position of the self-locking island 11, the guide block 14 automatically slides into the recess 12 of the self-locking island 11, locking the rotating disk 5 and keeping the data cable 4 at its extended length. At this time, the data cable 4 can be used stably and will not automatically rewind due to the elasticity of the spring 7.

[0035] When it's time to rewind the data cable 4, the user pulls the data cable 4 again, causing the guide block 14 to disengage from the notch 12 of the self-locking island 11. Then, the data cable 4 is released, and the spring 7 continues to drive the rotating disk 5 to rotate in the opposite direction, causing the guide block 14 to slide into the second guide groove 9. Guided by the second guide groove 9, the guide block 14 moves towards the return guide groove 10. As the guide block 14 approaches the return guide groove 10, the guide protrusion 15 within the second guide groove 9 activates, ensuring that the guide block 14 accurately enters the return guide groove 10 and preventing it from getting stuck or deviating from its path. After passing through the return guide groove 10, the guide block 14 re-enters the first guide groove 8, completing one full winding cycle.

[0036] The design of the guide protrusion 15 makes the movement of the guide block 14 at the return guide groove 10 smoother, avoiding winding failure or mechanism jamming due to the deviation of the guide block 14. When the data cable 4 is pulled out again, the guide block 14 slides along the first guide groove 8 again, repeating the above process to achieve stable pulling out and automatic winding of the data cable 4.

[0037] In this embodiment, the data cable 4 achieves self-locking and automatic winding functions through the cooperation of multiple guide grooves on the rotating disk 5 and the guide block 14 of the swing arm 6, combined with the auxiliary function of the guide protrusion 15. The structure of the rotating disk 5 is formed by one-time injection molding, which reduces the number of components, lowers production costs, and improves the reliability and service life of the mechanism.

[0038] Example 4:

[0039] In this embodiment, a winding mechanism 3 is movably mounted on the housing 1 via a main shaft 2, and a data cable 4 is fixedly connected to the winding mechanism 3. The winding mechanism 3 includes a rotating disk 5 and a swing arm 6. The rotating disk 5 is elastically connected to the main shaft 2 via a spring 7. The rotating disk 5 is provided with a first guide groove 8, a second guide groove 9, a return guide groove 10, and a self-locking island 11, with a notch 12 on the self-locking island 11. One end of the swing arm 6 is movably connected to the housing 1 via a first shaft 13, and the other end of the swing arm 6 is provided with a guide block 14. An offset protrusion 16 is provided on the opposite side of the notch 12 on the rotating disk 5. This offset protrusion 16 is used to guide the guide block 14 to disengage from the notch 12 and shift its position during the unlocking process.

[0040] When the user needs to pull out the data cable 4, pulling the data cable 4 outward causes the rotating disk 5 to rotate, at which point the spring 7 begins to store energy. The guide block 14 of the swing arm 6 slides relative to the first guide groove 8. As the rotating disk 5 rotates, the guide block 14 gradually approaches the self-locking island 11. When the user stops pulling the data cable 4, the rebound force of the spring 7 causes the rotating disk 5 to reverse. During the reversal, the guide block 14 automatically slides into the notch 12 of the self-locking island 11, realizing the self-locking of the rotating disk 5 and keeping the data cable 4 at the current pulled-out length.

[0041] When it is necessary to rewind the data cable 4, the user needs to gently pull the data cable 4 to unlock the rotating disk 5. At this time, the rotating disk 5 will rotate slightly, causing the guide block 14 to disengage from the recess 12. Since the rotating disk 5 has an offset protrusion 16 on the opposite side of the recess 12, when the guide block 14 disengages from the recess 12, the offset protrusion 16 will push the guide block 14 to shift its position, causing it to leave the circumferential path where the recess 12 is located. This offset design ensures that the guide block 14 will not slide back into the recess 12, but will accurately enter the second guide groove 9.

[0042] After the guide block 14 enters the second guide groove 9, the rebound force of the spring 7 continues to drive the rotating disk 5 to reverse and wind up the data cable 4. Since the guide block 14 has left the circumferential path of the notch 12 and is guided to the second guide groove 9 by the offset protrusion 16, the rotating disk 5 will not trigger the self-locking function again during the reversal process. The guide block 14 slides smoothly in the second guide groove 9 until the data cable 4 is completely wound up. This design ensures the smoothness of the data cable 4 winding process and avoids possible jamming during winding.

[0043] When data cable 4 is pulled out again, the rotary disk 5 rotates clockwise again. At this time, guide block 14 will re-enter the first guide slot 8 from the second guide slot 9 through the return guide slot 10, preparing for the next self-locking operation. The design of the return guide slot 10 ensures that guide block 14 can accurately return to the first guide slot 8, guaranteeing the rewinder's cyclical function.

[0044] This embodiment solves the problem of accidental locking that may occur after unlocking in traditional rewinders by setting an offset protrusion 16. The offset protrusion 16 causes the guide block 14 to make the necessary displacement after disengaging from the notch 12, ensuring that it can accurately enter the second guide groove 9 without getting stuck back into the notch 12 during the winding process. This design not only improves the reliability of winding but also simplifies the operation process. Users can easily complete the winding operation by simply pulling the data cable 4.

[0045] The multiple guide grooves and offset protrusions 16 on the rotating disk 5 can be manufactured using a one-time injection molding process, greatly reducing the number of components and assembly steps. This integrated design not only reduces production costs but also improves product reliability and durability. The entire winding mechanism 3 is compact, easy to operate, and effectively solves the problem of data cable 4 tangling and storage.

[0046] Example 5:

[0047] In this embodiment, a winding mechanism 3 is movably mounted inside the housing 1 via a main shaft 2, and a data cable 4 is fixedly connected to the winding mechanism 3. The winding mechanism 3 mainly consists of a rotating disk 5 and a swing arm 6. The rotating disk 5 is elastically connected to the main shaft 2 via a spring 7. The rotating disk 5 is provided with a first guide groove 8, a second guide groove 9, a return guide groove 10, and a self-locking island 11. The self-locking island 11 is provided with a notch 12 and a return protrusion 17. One end of the swing arm 6 is movably connected to the housing 1 via a first shaft 13, and the other end is provided with a guide block 14.

[0048] When the user needs to pull out the data cable 4, pulling the data cable 4 outward causes the rotating disk 5 to rotate, at which point the spring 7 begins to store energy. During the rotation of the rotating disk 5, the guide block 14 of the swing arm 6 slides relative to each other within the first guide groove 8. When the user releases the data cable 4, the spring 7 releases energy, causing the rotating disk 5 to reverse, and the guide block 14 continues to slide within the first guide groove 8. At this time, the return protrusion 17 on the self-locking island 11 plays a crucial role, ensuring that the guide block 14 accurately enters the recess 12 to achieve self-locking.

[0049] The design of the push-back protrusion 17 forces the guide block 14 into the recess 12 as it approaches the self-locking island 11. Specifically, when the rotating disk 5 reverses, the guide block 14 slides along the first guide groove 8 to the area of ​​the self-locking island 11, and the push-back protrusion 17 contacts the guide block 14 and pushes it toward the recess 12. This forced guidance mechanism greatly improves the success rate of self-locking and avoids the situation where the guide block 14 misses the recess 12 due to inertia or positional deviation.

[0050] When the data cable 4 needs to be fully wound up, the user pulls the data cable 4 again to disengage the guide block 14 from the notch 12. At this point, retracting the protrusion 17 will not obstruct the disengagement of the guide block 14. After releasing the data cable 4, the guide block 14 enters the second guide groove 9, and the spring 7 continues to drive the rotating disk 5 in reverse. The guide block 14 slides within the second guide groove 9 until the data cable 4 is fully wound up. During the next pull-out operation, the guide block 14 re-enters the first guide groove 8 via the return guide groove 10, preparing for the next use.

[0051] Example 6:

[0052] In this embodiment, a winding mechanism 3 is movably mounted on the housing 1 via a main shaft 2, and a data cable 4 is fixedly connected to the winding mechanism 3. The winding mechanism 3 includes a rotating disk 5 and a swing arm 6. The rotating disk 5 is elastically connected to the main shaft 2 via a spring 7. The rotating disk 5 is provided with a first guide groove 8, a second guide groove 9, a return guide groove 10, and a self-locking island 11. The self-locking island 11 is provided with a notch 12. One end of the swing arm 6 is movably connected to the housing 1 via a first shaft 13, and the other end of the swing arm 6 is provided with a guide block 14.

[0053] A sound block 19 is movably mounted inside the housing 1 via a second shaft 18. The sound block 19 has a protrusion 20, and a spring piece 21 is fixedly mounted on the housing 1, elastically connected to the sound block 19. The rotating disk 5 has a protruding ring 22 with a notch 23. When the rotating disk 5 rotates, the protrusion 20 engages with the notch 23 of the protruding ring 22, and under the elastic action of the spring piece 21, the sound block 19 vibrates periodically, thus producing a crisp sound and providing sound feedback to the user.

[0054] During use, when the user pulls the data cable 4 outward, the rotating disk 5 rotates accordingly, and the spring 7 stores energy. The guide block 14 of the swing arm 6 slides within the first guide groove 8. When the guide block 14 slides to the notch 12 of the self-locking island 11, the rotating disk 5 is locked, and the data cable 4 remains in the pulled-out state. At this time, the convex ring 22 of the rotating disk 5 rotates with the rotating disk 5, and the protrusion 20 of the clicker 19 repeatedly moves in and out of the notch 23 of the convex ring 22 under the action of the spring piece 21, producing a continuous "click" sound.

[0055] When the user needs to retract the data cable 4, pulling the data cable 4 again causes the guide block 14 to disengage from the notch 12 of the self-locking island 11, and the rotating disk 5 reverses under the action of the spring 7. The guide block 14 enters the second guide groove 9, the rotating disk 5 continues to rotate, and the data cable 4 gradually winds up. During this process, the convex ring 22 rotates in the opposite direction with the rotating disk 5, and the protrusion 20 of the clicker 19 continues to cooperate with the notch 23, emitting a regular sound to indicate to the user that the data cable 4 is being retracted.

[0056] Example 7:

[0057] In this embodiment, the rotating disk 5 is provided with a mounting base 24, which is a circular groove structure with an inner diameter matching the outer diameter of the mainspring 7. A central positioning post is provided at the bottom of the mounting base 24 for fixing the inner end of the mainspring 7. The mainspring 7 is made of stainless steel and has elastic recovery characteristics; its outer end is provided with a fixing hook. During assembly, the inner end of the mainspring 7 is first placed on the positioning post, and then a special spring coiling tool is used to pre-tighten the mainspring 7, causing its outer fixing hook to engage in the slot on the side wall of the mounting base 24.

[0058] The mounting base 24 has an annular step at its open end for mounting the cover plate 25. The cover plate 25 is a circular thin sheet structure with multiple snap-fits along its edges. During installation, the cover plate 25 is aligned with the opening of the mounting base 24, and pressure is applied to engage the snap-fits with the grooves on the inner wall of the mounting base 24. The cover plate 25 has a through hole in its center, allowing the spindle 2 to pass through. This structural design completely encloses the spring 7 within the mounting base 24, forming an independent energy storage assembly.

[0059] The rotating disk 5 and the mounting base 24 are manufactured using an integral injection molding process, and the material is engineering plastic. The inner wall of the mounting base 24 is provided with guide ribs to limit the radial displacement of the mainspring 7. After the cover plate 25 is installed, its inner surface maintains a small gap with the upper surface of the mainspring 7, which neither affects the rotation of the mainspring 7 nor prevents the mainspring 7 from coming off.

[0060] During use, when the user pulls the data cable 4 outward, the rotating disk 5 drives the mounting base 24 to rotate, causing the spring 7 to further tighten and store energy. When the data cable 4 is released, the elastic restoring force of the spring 7 drives the rotating disk 5 to rotate in the opposite direction, realizing automatic winding of the data cable 4. The mating structure between the mounting base 24 and the cover plate 25 ensures the stability of the spring 7 during operation, preventing the spring 7 from twisting or jamming.

[0061] The key to this embodiment lies in the modular design of the mainspring 7 assembly through the combination of the mounting base 24 and the cover plate 25. This design simplifies the assembly process; during final assembly, only the pre-assembled rotating disk 5 assembly needs to be connected to the spindle 2, eliminating the need for on-site adjustment of the mainspring 7 tension. Simultaneously, the enclosed structure protects the mainspring 7 from external contamination, extending its service life. The positioning pins and slots of the mounting base 24 ensure the accuracy of the mainspring 7's installation position, maintaining uniform winding force.

[0062] Example 8:

[0063] In this embodiment, the rotating disk 5 is provided with a first sliding hole 26, which forms a movable connection structure with the main shaft 2. A second sliding hole 27 is correspondingly provided on the cover plate 25, and a frustum 28 structure is provided on the housing 1. The second sliding hole 27 and the frustum 28 form a movable fit relationship. In the assembled state, the cover plate 25 is fixedly mounted on the rotating disk 5, ensuring that the axes of the first sliding hole 26, the second sliding hole 27, the frustum 28, and the main shaft 2 are completely coincident. The diameter of the frustum 28 is designed to be larger than the diameter of the main shaft 2, and the frustum 28 is positioned near the root of the main shaft 2.

[0064] During the assembly process, the spindle 2 passes through the second sliding hole 27 and the first sliding hole 26 in sequence, forming a tight sliding fit connection. Simultaneously, the frustum 28 also forms a tight sliding fit with the second sliding hole 27. This dual-support structure creates two independent movable support points, providing a stable support foundation for the rotational movement of the rotating disk 5. When the user pulls out or rewinds the data cable 4, the rotating disk 5 can maintain smooth rotation under the combined action of these two support points.

[0065] The working principle is as follows: by setting two coaxial sliding fit structures, the motion stability of the rotating disk 5 is significantly improved. The fit between the main shaft 2 and the first sliding hole 26 provides the main rotational support, while the fit between the frustum 28 and the second sliding hole 27 plays an auxiliary support role. The two support points work together to effectively prevent radial wobbling that may occur during the movement of the rotating disk 5. Positioning the frustum 28 at the root of the main shaft 2 ensures an appropriate distance between the two support points, further enhancing the stability of the rotating disk 5.

[0066] In actual use, when the user pulls out the data cable 4, the rotating disk 5 rotates smoothly on the main shaft 2, while the spring 7 begins to store energy. Due to the dual-support structure, there is no jamming or wobbling during rotation. When the user releases the data cable 4, the spring 7 releases energy, causing the rotating disk 5 to rotate in the opposite direction. At this time, the guide block 14 of the swing arm 6 slides within the guide groove of the rotating disk 5. Throughout the entire process, the rotating disk 5 maintains a stable rotational state and will not tilt due to single-point support.

[0067] With the data cable 4 locked in its length state, the rotating disk 5 remains in a fixed position through the cooperation of the swing arm 6 and the self-locking island 11. At this time, the dual-support structure continues to function, ensuring that the rotating disk 5 will not undergo unnecessary displacement due to external forces. When it is necessary to unlock, the user only needs to gently pull the data cable 4, and the rotating disk 5 will rotate smoothly under the protection of the dual-support structure, causing the guide block 14 to disengage from the self-locking state.

[0068] The dual-support structure ensures both the stability of the rotating disk 5 during rotation and the smoothness of operation. The synergistic effect of the two movable support points provides a good user experience whether the data cable 4 is being pulled out, locked, or retracted.
