Description

Technical Field

[0001] The utility model relates to the technical field of earphone wires, and in particular to an earphone wire positioning fixture. Background Art

[0002] Wires are an important part of headphones. Many properties of wires affect the sound quality of headphones, including plugs and pins. There are many kinds of wires, including copper wire, silver wire, copper-plated silver, copper-silver alloy wire, gold-silver alloy wire, etc. The function of the wire is to transmit the signal generated by the player to the headphones. A fixture is a large category of tools for carpentry, benchwork, ironwork, machinery, electronic control and some other handicrafts. It is mainly used to assist in controlling position or limiting movement, or both. It has a specific auxiliary positioning effect on the wire processing of headphones.

[0003] Chinese utility model patent application No. 202321449314.0 discloses an earphone wire positioning jig, which rotates the rocker to drive the gear to rotate, and the gear drives the soft toothed belt to rotate, thereby causing the jig body inside the soft toothed belt transmission to rotate. The two jig bodies rotate synchronously and drive the wire to rotate as a whole, avoiding the problem of re-fixing and removing the wire, and improving the processing efficiency of the wire.

[0004] However, when using the above patent to fix the headphone wire, secondary operations are required to complete the support and fixation of both ends of the headphone wire. This method of fixing the headphone wire will take longer time, thereby delaying the subsequent processing of the headphone wire. Therefore, it is necessary to design a headphone wire positioning fixture. Utility Model Content

[0005] In view of this, the utility model provides an earphone wire positioning fixture, the main technical problem to be solved is: the existing equipment is not convenient for supporting and fixing both ends of the earphone wire at the same time.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an earphone wire positioning fixture, comprising a bottom plate, the upper end of the bottom plate is fixedly connected to two support plates distributed on the left and right, the ends of the two support plates close to each other are fixedly connected to fixed rails, the ends of the two support plates close to each other are provided with support clamps, the end surfaces of the two support clamps away from each other are provided with sliding grooves, the two fixed rails extend into the two sliding grooves respectively, and are slidably connected to the two sliding grooves respectively, the two support clamps are connected by fasteners, and the fasteners are used to clamp and fix the earphone wire, the circumferential surfaces of the two support clamps are fixedly connected to gear rings, the lower end of the gear rings is installed with an angle adjustment mechanism, and the angle adjustment mechanism cooperates with the gear rings and is used to provide power for the gear rings to rotate;

[0007] By adopting the above technical solution, the two supporting clamps can first position the headphone wire, and then use fasteners to simultaneously support and fix the two ends of the headphone wire in the two supporting clamps. This makes fixing the headphone wire not only simpler and more convenient, but also makes the entire process of supporting and fixing the headphone wire more efficient because it takes less time.

[0008] The fastener includes a connecting rod circular plate, a spring, a fixing plate and a clamping plate, the top ends of the two supporting clamps' circumferential surfaces are fixedly connected to the fixing plates, the two supporting clamps are connected by a connecting rod, the left and right sides of the lower end of the connecting rod are fixedly connected to the clamping plates, the two clamping plates are respectively located in the two supporting clamps, the connecting rod passes through the two fixing plates and the supporting clamps, and is slidably connected to the two fixing plates and the two supporting clamps, the circumferential surface of the connecting rod is fixedly connected to the circular plate, a spring is arranged between the circular plate and the fixing plate, the spring is sleeved on the circumferential surface of the connecting rod, one end of the spring is fixedly connected to the circular plate, and the other end of the spring is fixedly connected to the fixing plate.

[0010] Furthermore, a guide rod is fixedly connected to the top end of the circumferential surface of the clamping plate. The guide rod passes through the supporting fixture and the fixing plate upwards and is slidably connected to both the supporting fixture and the fixing plate.

[0011] By adopting the above technical solution, under the action of the guide rod, the clamping plate and the connecting rod can move up and down more stably.

[0012] Furthermore, a plurality of self-locking universal wheels are fixedly connected to the lower end of the base plate.

[0017] By adopting the above technical solution, rotating the handle will drive the rotating rod to rotate, and then drive the second gear to rotate, the second gear will drive the first gear to rotate, and then drive the gear ring to rotate, and then drive the supporting clamp to rotate. As the supporting clamp rotates, the angle of the headphone wire inside the supporting clamp can be adjusted, thereby facilitating subsequent processing of different positions of the headphone wire.

[0018] Furthermore, a groove is provided on the left end faces of the two support plates, the radius of the groove is the same as the radius of the inner circle of the support fixture, and the bottom end face of the groove is in the same horizontal plane as the bottom end face of the inner cavity of the support fixture.

[0019] By adopting the above technical solution, the headphone wire can smoothly pass through the supporting clamp and the groove, so that the headphone wire can be supported by the overall device.
