DETAILED DESCRIPTION
[0029] The head-mounted MR glasses in the prior art usually have an external nose pad or an integrated nose pad, but the above-mentioned nose pad structure is simple but lacks movable joints. However, there are significant differences in the height, width and curvature of the bridge of the nose of different users. The height of the bridge of the nose of a human being can differ by 15-30 mm. The width of the bridge of the nose varies from 8 mm to 25 mm. The nose pad cannot adjust the angle or height. More than 60% of users feedback that there is a gap of 1-5 mm between the nose pad and the bridge of the nose, which causes the glasses to easily slide down along the bridge of the nose after being worn. The user needs to manually lift the frame to reset it every 15-30 minutes, which interferes with continuous work or immersion experience. Long-term compression of the weak area of the bridge of the nose (such as the upper part of the tip of the nose) causes skin marks or allergies, and long-term wearing by the user causes discomfort. The non-adjustable nature of the nose pad of the existing MR glasses is essentially a typical contradiction between standardized design and the diversity of human biological characteristics. This defect not only affects the wearing experience, but also causes optical performance degradation and health risks, which restricts the deep application of MR technology in key fields such as medical treatment and industry.
[0030] Therefore, in order to solve the technical problem that the position of the nose pad of the head-mounted MR glasses cannot be adjusted in the related art, cannot better adapt to more users in the face of differences between different users, and affects the wearing experience, the embodiments of the present application provide the following solutions.

In this way, the design of the first limiting groove 23 provides a clear limiting position for the rotating adjusting assembly 3, and ensures that the rotating adjusting assembly 3 can be accurately stopped at the preset angle position during rotation. This design avoids mechanical damage or function failure caused by excessive rotation, and the design of the limiting groove can provide a certain self-locking function to prevent accidental rotation under external vibration or impact.
[0035] In the present embodiment, the rotating adjusting assembly 3 comprises a rotating column 31 arranged in the connecting piece 21, and a clamping piece 32 is arranged on both ends of the rotating column 31, and the clamping piece 32 is rotatably sleeved with the clamping ring 22.
[0036] In this way, the clamping piece 32 is convenient for clamping with the clamping ring 22, the rotating column 31 is convenient for connecting the telescopic adjusting assembly 4 and driving the rotation adjustment angle.

[0038] In this way, the first spring 331 in the first limiting piece 33 telescopes and abuts against the first clamping block 332 in the first limiting groove 23, and mechanical limiting is realized. In this way, the action of the first spring 331 enables the first clamping block 332 to maintain a stable limiting position in the first limiting groove 23, ensuring that it can accurately stay at the preset position under various working conditions. This accurate limiting can improve the overall accuracy and reliability of the equipment, and the elastic force of the spring can prevent the first clamping block 332 from loosening or shifting when subjected to vibration or impact, ensuring the stability of the mechanical structure. This design can improve the working performance of the equipment in harsh environments.
[0039] In the present embodiment, the telescopic adjusting assembly 4 comprises a fixing sleeve 41 arranged on the rotating column 31, a second limiting groove 43 is formed in the inner wall of the fixing sleeve 41, the connecting frame 11 is sleeved in the fixing sleeve 41, a second limiting piece 42 is arranged on the connecting frame 11, the second limiting piece 42 comprises a second spring 421 and a second clamping block 422, a second connecting groove 423 is formed in the outer wall of the connecting frame 11, the second spring 421 is arranged in the second connecting groove 423, and the second clamping block 422 is arranged on one end of the second spring 421 away from the second connecting groove 423.
[0040] In this way, by making the connecting frame 11 extend or retract in the fixed sleeve 41, the second connecting groove 423 on the connecting frame 11 makes the second spring 421 in the second connecting groove 423 extend or retract to abut against the second clamping block 422 in the second limiting groove 43, thereby achieving mechanical limiting. In this way, the action of the second spring 421 enables the second clamping block 422 to remain in a stable limiting position in the second limiting groove 43, thereby ensuring that the connecting frame 11 can accurately stop at a preset length position during extension or retraction. This accurate limiting can improve the extension accuracy of the connecting frame 11 and the stability of the overall structure.

[0042] In this way, the entire nose pad mechanism is fixed on the glasses through the connecting lug 24, thereby being firmly fixed. In this way, the design of the connecting lug 24 can ensure that the nose pad mechanism and the glasses body are firmly connected, thereby avoiding loosening or falling off during daily use. This stable fixing can improve the overall durability and service life of the glasses.
[0043] In this embodiment, the first limiting groove 23 and the second limiting groove 43 are both arc-shaped structures, and the first clamping block 332 and the second clamping block 422 are both cylindrical structures.
[0044] In this way, the cylindrical clamping block can be easily inserted into and withdrawn from the arc-shaped limiting groove, and the user can conveniently assemble and disassemble the device. This design improves the user experience and operational convenience. The arc-shaped limiting groove and the cylindrical clamping block cooperate to make the movement trajectory of the clamping block in the limiting groove smoother.
