Technical Field
[0001] This utility model relates to the field of headphone sliding arm adjustment technology, and in particular to a sliding arm adjustment component for over-ear headphones. Background Technology
[0002] Over-ear headphones generally consist of a headband, sliding arms, and earcups. The earcups are slidably connected to the sliding arms. The headband and sliding arms are adjusted via an adjustment mechanism to allow the earcups to fit the user's ears. When wearing over-ear headphones, users want the headphones to fit snugly against their heads without causing excessive pressure, in order to achieve optimal wearing comfort. The sliding arm adjustment mechanism allows users to make fine adjustments according to the size and shape of their heads, thereby ensuring that the headphones are both secure and comfortable to wear.
[0003] Most existing sliding arm assemblies involve sliding arms that are inserted into openings on both sides of a fixed arm. The size of the headphones can be adjusted by manually pulling the sliding arms outwards before they can be worn. However, most existing sliding arm assemblies use an insertion connection, which can become loose due to wear after repeated sliding and insertion over a long period of time.
[0004] Therefore, it is necessary to provide a new sliding arm adjustment assembly for headphones to solve the above-mentioned technical problems. Utility Model Content

[0018] This utility model provides a sliding arm adjustment component for a headset;
[0019] 1. This utility model can adjust the size of the headphones through the set adjustment structure. When the user wears the headphones, the headphones can be manually put on the head. By manually rotating the two sets of knobs, the two sets of shafts are rotated, which in turn rotates the transmission gears. This causes the locking teeth on the adjustment side of the transmission gears to move, which causes the adjustment plate to extend and retract outward. This causes the sliding arms fixedly connected to the lower ends of both sides of the adjustment plate to slide downward and expand. After the sliding arms expand to the specified size, the size adjustment is completed, thereby realizing the expansion of the size of the headphones.
[0020] 2. This utility model can fix the size of the expanded headphones by setting a limiting structure. After the headphones are expanded to the required size, the slider can be pushed manually to move the slider to the inside of the groove, and the pin at the bottom of the slider can be inserted into the locking teeth on one side of the adjustment plate, thereby achieving the limiting and fixing of the size of the expanded headphones.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0027] Please see Figures 1 to 3 This utility model provides a sliding arm adjustment assembly for a headset, the sliding arm adjustment assembly for the headset comprising:
[0028] Fixed arm 1, with adjustment structures on both sides;
[0029] The adjustment structure includes a knob 3, a slot 14, an adjustment plate 15, and a transmission gear 16. Slots 14 are provided on both sides of the fixed arm 1. The adjustment plate 15 is slidably connected inside the two sets of slots 14. A locking tooth 17 is fixedly connected to one side of each of the two sets of adjustment plates 15. Multiple sets of locking teeth 17 are provided. Through holes are provided on both sides of the top of the fixed arm 1. A knob 3 is rotatably connected to both sides of the top of the fixed arm 1. A rotating shaft 19 is fixedly connected to the lower end of each of the two sets of knobs 3. The lower end of each of the two sets of rotating shafts 19 passes through the through hole and is fixedly connected to the end of the transmission gear 16. Both sets of transmission gears 16 are engaged with the locking teeth 17 of the adjustment plate 15. A sliding arm 4 is fixedly connected to the lower end of each of the two sets of adjustment plates 15.
[0030] The limiting structure is provided on both sides of the fixed arm 1. The limiting structure includes a sliding groove 11, a slider 18 and a pin 20. Sliding grooves 11 are provided on both sides of the fixed arm 1. Sliding sliders 18 are slidably connected to both sets of sliding grooves 11. Pins 20 are fixedly connected to the lower ends of both sets of sliders 18. Pins 20 are movably connected to the locking teeth 17 of the adjusting plate 15.
[0031] It should be noted that when using the headphones, the user can manually put the headphones on their head and rotate the two sets of rotating knobs 3 to rotate the two sets of rotating shafts 19, which in turn rotates the transmission gear 16. This causes the locking teeth 17 on one side of the adjustment 15, which is engaged with the transmission gear 16, to move. This causes the adjustment plate 15 to extend and retract outward, and causes the sliding arms 4, which are fixedly connected to the lower ends of both sides of the adjustment plate 15, to slide downward and expand. After the sliding arms 4 expand to the specified size, the size adjustment is completed, thereby expanding the size of the headphones. After the headphones are expanded to the required size, the slider 18 can be manually pushed to slide the slider 18 inward in the slide groove 11. This causes the pin 20 at the bottom of the slider 18 to insert into the locking teeth 17 on one side of the adjustment plate 15, thereby limiting and fixing the size of the expanded headphones without wearing down the connecting parts to adjust the size of the headphones.
[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The lower end of each sliding arm 4 is fixedly connected to an earcup 5, through which audio can be played.

[0034] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 Each earcup 5 has a connecting ring 8 fixedly connected to its back side, and a connecting buckle 9 fixedly connected to the center of the connecting ring 8. The position of the earphone can be fixed by the connecting buckle 9 in conjunction with the connecting ring 8.
[0035] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The lower end of the fixed arm 1 is fitted with a buffer pad 2, which can protect the user's head.
[0036] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The inner side of each earmuff 5 is fixedly connected with a protective pad 6, which can protect the user's ears.
[0037] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The bottom of the earcup 5 is fixedly connected to a connecting line 10, and a controller 12 is installed at the center of the connecting line 10. The controller 12 can be used to operate all electronic components in a unified manner.
[0038] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The controller 12 is equipped with a button 13, which can be used to operate the controller 12.
[0039] The working principle of the sliding arm adjustment component for the headphones provided by this utility model is as follows:
[0040] When using the headphones, the user first manually puts the headphones on their head. By manually rotating the two sets of knobs 3, the two sets of shafts 19 are rotated, which in turn rotates the transmission gear 16. This causes the locking teeth 17 on one side of the adjustment 15, which is engaged with the transmission gear 16, to move. This causes the adjustment plate 15 to extend and retract outward, and the sliding arms 4, which are fixedly connected to the lower ends of both sides of the adjustment plate 15, slide downward to expand. After the sliding arms 4 expand to the specified size, the size adjustment is completed, thereby expanding the size of the headphones. After the headphones are expanded to the required size, the slider 18 can be manually pushed, causing the slider 18 to slide inward in the slide groove 11. This causes the pin 20 at the bottom of the slider 18 to insert into the locking teeth 17 on one side of the adjustment plate 15, thereby limiting and fixing the size of the expanded headphones without wearing down the connecting parts to adjust the size of the headphones.
[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
