[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.
[0030] WITH REFERENCE Figure 1 AND Figure 2 An embodiment provided by the utility model: high fidelity earphone wire tensile resistance protection device, including earphone wire 1, earphone wire 1 one end electric connection has earphone head 2, for output audio signal, make earphone can play sound, earphone wire 1 inside is provided with controller 3, for adjusting volume, switching music or carrying out other operation, controller 3 usually is integrated in the certain section of earphone wire 1, convenient for user to carry out convenient control, earphone wire 1 outer wall is provided with connecting sleeve 4, connecting sleeve 4 inside is provided with connecting line 5, connecting line 5 and earphone wire 1 are connected, connecting line 5 one end electric connection has connector 6, earphone wire 1 outer wall is provided with protection assembly;
[0031] The protection assembly comprises a sliding frame 7 which is slidingly connected to the outer wall of the earphone wire 1, a limiting block one 8 which is fixedly connected to the inside of the sliding frame 7, and a limiting block two 9 which is fixedly connected to the inside of the sliding frame 7.
[0032] Specifically, when one of the earphone wires 1 is stretched by external force, the sliding frame 7 will move along the stretching direction of the earphone wire 1. In order to ensure the stability of the earphone wire 1 and prevent the earphone wire 1 from being excessively stretched or twisted, the limiting block one 8 and the limiting block two 9 are arranged in the sliding frame 7. The two limiting blocks play a limiting role in limiting the free movement range of the earphone wire 1 in the sliding frame 7, thereby avoiding the earphone wire 1 from being affected by excessive tension or rotational force during the stretching process and preventing damage or wear. The limiting block one 8 and the limiting block two 9 have a certain elasticity, which can effectively relieve the tension of the earphone wire 1, so that the earphone wire 1 is more durable and safe during use. Meanwhile, when it is necessary to remove the sliding frame 7 from the earphone wire 1, the earphone wire 1 can be easily taken out from the inside of the sliding frame 7 by applying appropriate pressure to the limiting block one 8 and the limiting block two 9, which can provide a convenient dismounting function.
[0033] Referring to Figures 1-3 The limiting assembly comprises a sliding column 10 which is slidingly connected to the inside of the sliding frame 7, and a clamping block 11 which is fixedly connected to the bottom end of the sliding column 10. The bottom of the clamping block 11 is fixedly connected with a protruding block 12 which is in contact with the earphone wire 1. The protruding block 12 directly contacts the earphone wire 1 to limit the free movement of the earphone wire 1. The top end of the sliding column 10 is fixedly connected with a blocking ring 13 which limits the movement range of a sliding plate 14. The sliding plate 14 is slidingly connected to the outer wall of the sliding column 10. The top of the sliding plate 14 is fixedly connected with a pull ring 15 which provides a convenient operation mode when the user manually pulls the sliding frame 7. The outer wall of the sliding column 10 is sleeved with a spring 16 which is fixedly connected to the clamping block 11 and the inside of the sliding frame 7 at both ends. The limiting block one 8 and the limiting block two 9 are made of rubber material.
[0034] Specifically, when the user needs to adjust the position of the sliding frame 7 on the outer wall of the earphone wire 1, the user can make the sliding plate 14 slide along the outer wall of the sliding column 10 by pulling the pull ring 15. The sliding plate 14 drives the blocking ring 13 to move, and the blocking ring 13 drives the sliding column 10 to slide in the sliding frame 7, thereby adjusting the position of the sliding frame 7. The bottom end of the sliding column 10 is provided with the clamping block 11 which limits the position of the earphone wire 1 by contacting the outer wall of the earphone wire 1. When the adjustment is completed, the spring 16 will quickly release the force and rebound to restore the clamping block 11 to the initial position, thereby ensuring that the clamping block 11 is re-clamped on the outer wall of the earphone wire 1 to achieve stable fixation of the earphone wire 1.
[0035] Working principle: when one of the earphone wires 1 is stretched by external force, the sliding frame 7 will move along the stretching direction of the earphone wire 1, and because of the existence of the limiting block one 8 and the limiting block two 9, they will limit the movement range of the earphone wire 1 in the sliding frame 7, avoid the earphone wire 1 from being stretched or twisted too much, thereby playing a preliminary protection role, making the position of the sliding frame 7 on the earphone wire 1 relatively stable and not easily sliding, and the limiting block one 8 and the limiting block two 9 have a certain elasticity, when it is needed to take the sliding frame 7 out of the earphone wire 1, only need to extrude and shrink the limiting block one 8 and the limiting block two 9 through the earphone wire 1, so as to take the earphone wire 1 out of the sliding frame 7, thereby facilitating the effect of limiting protection of the two earphone wires 1, when it is needed to adjust the position of the sliding frame 7 on the outer wall of the earphone wire 1, only need to pull the pull ring 15, so as to drive the sliding plate 14 to slide on the outer wall of the slide column 10, and the sliding plate 14 drives the blocking ring 13 to move, the blocking ring 13 drives the slide column 10 to slide in the sliding frame 7, the slide column 10 drives the clamping block 11 at the bottom to move, so as to separate from the outer wall of the earphone wire 1, and the clamping block 11 compresses the spring 16 at the top, at this time, the sliding frame 7 can be pulled to slide on the outer wall of the earphone wire 1, and after being adjusted to the required position, only need to release the pull ring 15, and through the unloading rebound of the spring 16, thereby driving the clamping block 11 to reset, so as to be clamped on the outer wall of the earphone wire 1 for limiting, thereby achieving the effect of facilitating the adjustment of the position of the sliding frame 7.
[0036] Finally, it should be pointed out that: the above only for preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. made within the spirit and principle of the utility model, should be contained in the protection scope of the utility model.
