Technical Field
[0001] This utility model relates to the field of headphone manufacturing technology, specifically to a splicing hand-cranked headphone cable spraying and fixing fixture. Background Technology
[0002] Nowadays, mobile phone earphones are a very common mobile phone accessory, and almost every mobile phone comes with one. In order to improve the user's comfort and increase the quality and durability of the product, a layer of hand-feel oil or other protective film of different materials is usually applied to the earphone cable. In the past, the spraying method was mostly done manually. This most traditional processing mode requires a lot of labor costs and has many safety hazards and drawbacks. With the continuous advancement of technology, mechanical spraying has gradually replaced manual operation. However, due to the limitations of program settings and mechanical travel paths, there are still uneven processing areas, resulting in unsatisfactory coating effects. Often, a second spraying process is required, which cannot ensure the production efficiency and yield rate of the product.
[0003] The existing Chinese patent CN207695033U describes a combined hand-cranked headphone cable spraying and fixing fixture. However, in addressing the aforementioned problem, it does not limit the spraying flip frame, which causes the spraying flip frame to flip when fixing the headphone cable, thus affecting the headphone cable fixing operation and making it unsuitable for widespread use.

[0029] A fixed support plate 17 is fixedly connected to the inner cavity of the movable frame 3 near the front side. A first pressure plate 18 is provided on the top of the fixed support plate 17. A first handle 19 is fixedly connected to the top of the first pressure plate 18 near the center position. A first fixed frame 20 is provided on the top of the first pressure plate 18 near the left and right sides. The first fixed frame 20 is fixedly connected to the top of the movable frame 3. A first vertical rod 21 is movably passed through the first fixed frame 20. The first vertical rod 21 is fixedly connected to the top of the first pressure plate 18. A second spring 22 is movably sleeved on the outer edge of the first vertical rod 21 near the top. A first limiting plate 23 is fixedly connected to the top of the first vertical rod 21. The two ends of the second spring 22 are fixedly connected to the first fixed frame 20 and the first limiting plate 23, respectively.
[0030] The movable frame 3 has a movable support plate 24 near the rear side of its inner cavity. The movable frame 3 has sliding grooves 25 on both the left and right sides. The movable support plate 24 moves through the adjacent sliding grooves 25 on both sides. The top of the movable support plate 24 has a second pressure plate 26.

The two ends of the third spring 32 are fixedly connected to the second fixing frame 30 and the second limit plate 33, respectively.
[0031] Working principle: This utility model is a splicing hand-cranked headphone cable spraying and fixing fixture. During use, first pull the first handle 19 upward. The first handle 19 drives the first pressure plate 18 to move upward. The first pressure plate 18 drives the first vertical rod 21 and the first limiting plate 23 to move upward. At the same time, the second spring 22 is stretched. At this time, the distance between the first pressure plate 18 and the fixed support plate 17 increases. Then, place one end of the headphone cable between the first pressure plate 18 and the fixed support plate 17. Then slowly release the upward force on the first handle 19. Under the elastic action of the second spring 22, the first pressure plate 18 moves downward. The downward movement of the first pressure plate 18 clamps and fixes one end of the headphone cable to the top of the fixed support plate 17.
[0032] Then pull the second handle 27 upwards. The second handle 27 drives the second pressure plate 26 and the limiting block 28 to move upwards. The limiting block 28 moves away from the limiting groove 29. The second pressure plate 26 drives the second vertical rod 31 and the second limiting plate 33 to move upwards. At the same time, the third spring 32 is stretched. At this time, the distance between the second pressure plate 26 and the movable support plate 24 increases, maintaining the upward pulling force on the second handle 27. Then move the second handle 27 back and forth. The second handle 27 drives the second fixed frame 30, the movable support plate 24 and the second pressure plate 26 to move together until the rear movable support plate 24 is in contact with the fixed frame 30. The horizontal distance between the front sides of the tray 17 is equal to the length of the headphone cable. At this time, stop moving the second handle 27 back and forth, and then place the other end of the headphone cable between the movable tray 24 and the second pressure plate 26. Then slowly release the upward force on the second handle 27. The second pressure plate 26 moves downward under the elastic action of the third spring 32. The second pressure plate 26 drives the limiting block 28 to insert into the inner cavity of the adjacent limiting groove 29. The second pressure plate 26 moves downward to clamp and fix the other end of the headphone cable to the top of the movable tray 24, thus completing the fixation of the headphone. After that, the headphone cable is sprayed.
[0033] By adjusting the position of the movable support plate 24 and the second pressure plate 26, the device can be used to fix headphone cables of different lengths, greatly improving the applicability of the device.
[0034] When it is necessary to flip the movable frame 3, place your foot inside the pedal frame 16 and then press down on the pedal frame 16. The pedal frame 16 drives the connecting rod 13, the circular plate 14 and the movable plate 9 to move downward. At the same time, the first spring 15 is compressed, and the movable plate 9 drives the toothed block 10 to move away from the gear 7, thereby releasing the fixation between the first rotating shaft 4 and the movable frame 3. Then, the rocker wheel 8 drives the first rotating shaft 4 and the movable frame 3 to flip. After the movable frame 3 is flipped to a suitable angle, slowly release the downward force on the pedal frame 16. The pedal frame 16, the connecting rod 13, the circular plate 14 and the movable plate 9 move upward under the elastic action of the first spring 15. The movable plate 9 then drives the toothed block 10 to move to mesh with the gear 7, thereby fixing the movable frame 3.
[0035] The device uses the movable plate 9 and the toothed block 10 to fix the movable frame 3, so that the movable frame 3 can be fixed after being flipped to a suitable angle, thus preventing the movable frame 3 from flipping randomly and affecting the normal operation of the headphone wire spraying work.
