Description

Technical Field

[0001] This utility model belongs to the field of headphone cables, specifically an anti-tangling headphone cable. Background Technology

[0002] Headphone cables, serving as the connection medium between headphones and audio devices, are primarily responsible for transmitting audio signals. They consist of four internal wires responsible for the left channel, right channel, ground, and microphone, respectively. The outer layer of headphone cables is usually wrapped with insulating material to protect the wires from damage and ensure the stability of signal transmission.

[0003] Existing earphones are prone to tangling during use and storage. Therefore, a storage box is usually provided in the middle of the earphone cable to store it. A search revealed a Chinese patent with publication number CN218788830U that mentions an earphone with an anti-tangling design. Through the linkage of a storage mechanism and a limiting mechanism, when in use, pushing the moving plate moves it within a through groove, causing the rack plate to move and separate from the gear. At this time, pulling the earphone cable body can remove the earphone cable body for easy use. When not in use, pushing the moving plate rotates the rotating disk, which in turn rotates the transmission rod, causing the storage platform to rotate, thereby winding the earphone cable body into the storage platform.

[0004] However, when storing or using the headphone cable, it is necessary to push the moving plate and then perform the next operation simultaneously. That is, during the storage process, one hand needs to push the moving plate and the other hand needs to rotate the dial. This requires continuous two-handed operation, which increases the user's burden and reduces the user experience.

[0005] To address this issue, those skilled in the art have proposed an anti-tangling headphone cable to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an anti-tangling headphone cable, which solves the problems in the prior art where storing or using headphone cables requires continuous two-handed operation, increasing the user's burden and reducing the user experience.

[0007] An anti-tangling headphone cable includes a headphone cable body and a storage box. A rotating shaft is rotatably arranged inside the storage box. Two sets of limiting plates are symmetrically arranged on the rotating shaft. The middle part of the headphone cable body is wound around the rotating shaft and located between the two limiting plates. The two ends of the headphone cable pass through the storage box and are connected to the headphone head and the plug, respectively.

[0008] A limiting groove is provided at one end of the rotating shaft, and a limiting rod is slidably installed on the limiting groove. A baffle is connected to the middle of the limiting rod, and a spring sleeved on the outside of the limiting rod is abutted between the baffle and the inner wall of the storage box. A pull shaft passing through the storage box is connected to one end of the limiting rod, and a rotation limiting component is provided at the end of the pull shaft.

[0009] Preferably, both ends of the top of the storage box are provided with a gathering cover, which is set as an open structure, and its shape and size are matched with the shape and size tolerance of the earphone head.

[0010] Preferably, both the limiting groove and the limiting rod have square cross-sections, and the limiting rod is slidably connected to the rotating shaft through the limiting groove.

[0011] Preferably, the rotation limiting component includes a handle, a retaining ring, and a rotating seat. The retaining ring and the rotating seat are both disposed on the outer wall of the storage box. The rotating seat is rotatably connected to the storage box, and the retaining ring is fixedly connected to the storage box. One end of the pull shaft passes through the retaining ring and the rotating seat in sequence and is connected to the handle.

[0012] Preferably, the rotating seat has an integrally formed connecting portion extending into the range of the retaining ring, and the connecting portion has a through hole in the middle for the pull shaft to pass through.

[0013] Preferably, the handle is configured as a strip structure, with a first groove on both sides of the end face of the retaining ring and a second groove on both sides of the end face of the rotating seat. The first groove and the second groove are arranged in a cross-shaped staggered arrangement, and the shapes of the first groove and the second groove are adapted to the shape of the handle.

[0014] Compared with the prior art, this utility model has the following advantages: This utility model uses a rotating shaft inside the storage box to store the headphone cable. At the same time, a rotation limiter is movably set at one end of the rotating shaft via a limiting rod. When it is necessary to drive the rotating shaft to rotate, with the cooperation of the spring, baffle, rotating seat and retaining ring, by pulling the handle, the handle moves the limiting rod outward. During the movement, the handle disengages from the first retaining groove on the retaining ring. Then, the handle is rotated to align with the second retaining groove on the rotating seat. Then, the external pulling force on the handle is released, so that it abuts against the second retaining groove under the action of the spring. At this time, when storing the headphone cable, only one hand needs to rotate the rotating seat, eliminating the need for continuous two-hand operation and improving the user experience.

[0022] The following detailed description of the limiting mechanism of this utility model, in conjunction with the accompanying drawings and embodiments, is provided. The following embodiments are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides an anti-tangling headphone cable, including a headphone cable body 1 and a storage box 2. A rotating shaft 3 is rotatably arranged inside the storage box 2. Two sets of limiting plates 4 are symmetrically arranged on the rotating shaft 3. The middle part of the headphone cable body 1 is wound on the rotating shaft 3 and located between the two limiting plates 4. The two ends of the headphone cable pass through the storage box 2 and are connected to the headphone head 5 and the plug 6, respectively. A limiting groove 7 is opened at one end of the rotating shaft 3. A limiting rod 8 is slidably arranged on the limiting groove 7. A baffle 9 is connected to the middle of the limiting rod 8. A spring 10 sleeved on the outside of the limiting rod 8 abuts between the baffle 9 and the inner wall of the storage box 2. A pull shaft 11 passing through the storage box 2 is connected to one end of the limiting rod 8. A rotation limiting component is provided at the end of the pull shaft 11.

[0025] refer to Figure 1 Both ends of the top of the storage box 2 are provided with a gathering cover 12. The gathering cover 12 is set as an open structure, and its shape and size are matched with the shape and size tolerance of the earphone head 5.

[0026] The headphone head 5 is stored in the conduit 12. When the headphone cable body 1 is stored, the exposed length of the headphone cable body 1 becomes shorter, which will cause the headphone head 5 to move into the conduit 12, preventing the headphone head 5 from swinging around when the headphone cable body 1 is stored.

[0027] refer to Figure 3 The cross-sections of the limiting groove 7 and the limiting rod 8 are both set to square, and the limiting rod 8 is slidably connected to the rotating shaft 3 through the limiting groove 7.

[0028] The square shape allows the two to be in a relative limiting state, meaning that rotating the limiting rod 8 will drive the rotating shaft 3 to rotate synchronously.

[0029] refer to Figure 2 The rotation limiting component includes a handle 13, a retaining ring 14, and a rotating seat 15. The retaining ring 14 and the rotating seat 15 are both set on the outer wall of the storage box 2. The rotating seat 15 is rotatably connected to the storage box 2, and the retaining ring 14 is fixedly connected to the storage box 2. One end of the pull shaft 11 passes through the retaining ring 14 and the rotating seat 15 in sequence and is connected to the handle 13.

[0030] When the handle 13 is engaged with the rotating seat 15, the rotating seat 15 and the storage box 2 are in a rotating connection state. Therefore, the handle 13 can be rotated by rotating the rotating seat 15, so that the handle 13 drives the rotating shaft 3 to rotate through the limiting rod 8 to store the headphone cable body 1. When the handle 13 is engaged with the retaining ring 14, the retaining ring 14 is fixed, so the handle 13 is in a limited state and remains stationary. That is, the rotating shaft 3 keeps the headphone cable body 1 fully stored.

[0031] refer to Figure 3 and Figure 4 The rotating seat 15 has an integrally formed connecting part 16 extending into the range of the retaining ring 14, and the connecting part 16 has a through hole 17 in the middle for the pull shaft 11 to pass through.

[0032] refer to Figure 1 and Figure 5 The handle 13 is set as a strip structure. The two sides of the end face of the retaining ring 14 are provided with first retaining grooves 18 and the two sides of the end face of the rotating seat 15 are provided with second retaining grooves 19. The first retaining grooves 18 and the second retaining grooves 19 are arranged in a cross-shaped staggered manner, and the shapes of the first retaining grooves 18 and the second retaining grooves 19 are adapted to the shape of the handle 13.

[0033] Specifically, by placing the handle 13 in the first slot 18, the handle 13 is limited by the retaining ring 14. By placing the handle 13 in the second slot 19, the limitation is released, and the handle 13 can be rotated by the rotating seat 15.

[0034] Working principle: During use, when it is necessary to store the headphone cable body 1, first pull the handle 13 outward. Under the pulling force, the handle 13 will move the limiting rod 8 outward through the pull shaft 11. When the limiting rod 8 moves, it will cause the baffle 9 to squeeze the spring 10. On the other hand, the handle 13 itself will disengage from the first slot 18. At this time, rotate the handle 13, so that the handle 13 drives the rotating shaft 3 to rotate synchronously through the limiting rod 8. During the rotation, the handle 13 is aligned with the second slot 19. At this time, release the outward pulling force. Under the restoring force of the spring 10, the baffle 9 drives the limiting rod 8 to move outward. When the limit rod 8 is reset, it drives the handle 13 to abut against the second slot 19 through the pull shaft 11. At this time, by rotating the rotating seat 15, the rotating seat 15 will drive the handle 13 to rotate synchronously due to the engagement state between the second slot 19 and the handle 13. When the handle 13 rotates, it drives the rotating shaft 3 to store the headphone cable body 1 through the limit rod 8. After storage, pull the handle 13 outward again and rotate it to align it with the first slot 18. Then release the outward pull force to make it engage with the first slot 18 and form a relative limit with the retaining ring 14. At this time, the headphone cable body 1 will remain in the stored state and will not automatically loosen.
