Description

Technical Field

[0001] This utility model relates to the field of helmet and headphone technology, and in particular to a wear-resistant structure for adjusting the angle of a helmet and headphone. Background Technology

[0002] Helmet headsets are used to mount and secure themselves to helmets. Current helmet headsets consist of a headset body and an angle adjustment mechanism. One end of the angle adjustment mechanism is hinged to the headset body, and the other end is clamped to the helmet. The angle adjustment mechanism includes a plastic or metal adjustment plate. One end of the plastic or metal adjustment plate is connected to the headset body via a pre-formed shaft, while the other end is clamped to the helmet. The headset body and the pre-formed shaft of the plastic or metal adjustment plate achieve a rotatable connection, with the rigid material of the adjustment plate creating a damping effect against the rigid plastic material of the headset body. However, this angle adjustment structure has some shortcomings. After a period of use, due to friction, the plastic parts will wear down, weakening the damping effect and causing the headset body and adjustment plate to loosen, preventing it from being fixed in the correct position. Furthermore, to increase the strength of the plastic adjustment plate, it needs to be made relatively thick and large. Utility Model Content
