In this way, the stoppers at both ends of the sliding rail can stop the sliding block to prevent the sliding block from detaching from the sliding rail, thereby preventing the second connecting member 32 from detaching from the first connecting member 31 during the height adjustment process of the nose pad 2. Among them, the slide rail is a horse-riding slide rail.

As another example, as shown in FIG. 4, the limiting structure 5 includes a first sliding groove 51 and a sliding member 52. As shown in FIG. 7, the first sliding groove 51 extends along the axial direction of the first connecting member 31. The two ends of the groove 51 are closed, the sliding member 52 is slidingly matched with the first sliding groove 51, the first sliding groove 51 is disposed on the first connecting member 31, and the sliding member 52 is disposed on the second connecting member 32.

Connected, the other end of the second sliding groove 6 penetrates the end surface of the first connecting member 31, and the sliding member 52 can slide into the second sliding groove 6 from the first sliding groove 51 and slide out along the second sliding groove 6 to realize the first The separation of the second connecting member 32 and the first connecting member 31. In this way, by separating the second connector 32 and the first connector 31, the nose pad 2 can be removed from the lens frame 1 to repair or replace the nose pad 2, thereby reducing the maintenance cost of the glasses.

In the above-mentioned embodiment, the second sliding groove 6 may communicate with the end of the first sliding groove 51 or the middle of the first sliding groove 51, which is not specifically limited here. In some embodiments, as shown in FIG. 7, the second sliding groove 6 communicates with the end of the first sliding groove 51. In this way, it is only necessary to drive the second connecting member 32 to slide in the first connecting member 31, so that the sliding member 52 slides to the end of the first sliding groove 51, and the disassembly process can be entered without repeatedly searching for the first sliding groove 51. The position communicating with the second sliding groove 6 can simplify the separation process between the second connecting member 32 and the first connecting member 31 and reduce the difficulty of removing the nose pad 2 from the lens frame 1.

The second sliding groove 6 may extend in a spiral shape surrounding the inner wall of the first connecting member 31, or may extend in a serpentine shape, which is not specifically limited here, as long as the extension direction of the second sliding groove 6 is the same as that of the first sliding groove 51 The direction is different to avoid the sliding member 52 sliding into the second sliding groove 6 from the first sliding groove 51 and sliding out along the second sliding groove 6 during the height adjustment process of the nose pad 2, thereby avoiding the height adjustment of the nose pad 2. During the process, the second connecting member 32 is separated from the first connecting member 31.

In this way, the process of removing the nose pad 2 from the lens frame 1 can be as follows: first drive the second connecting member 32 to slide in the first connecting member 31, so that the sliding member 52 moves to the second sliding groove 6 and the first sliding groove 51 is connected to the position, and then rotate the second connecting piece 32 relative to the first connecting piece 31, so that the sliding piece 52 slides along the third sliding groove 61 to the end of the third sliding groove 61 away from the first sliding groove 51, and finally again The second connecting member 32 is driven to slide in the first connecting member 31, so that the sliding member 52 slides along the fourth sliding groove 62 to one end of the fourth sliding groove 62 that penetrates the end surface of the first connecting member 31, and the fourth sliding member The groove 62 penetrates through one end of the end surface of the first connecting member 31 and slides out. The installation process is opposite to the disassembly process, which is simple and easy to implement.

In some embodiments, the center angle corresponding to the third sliding groove 61 is 70°˜110°. In this way, the length of the third chute 61 is moderate, which can avoid the possibility of the sliding member 52 coming out of the first chute 51 due to the excessively short length of the third chute 61, and at the same time can avoid The length of 61 is too long, which increases the difficulty of separation and installation between the second connecting member 32 and the first connecting member 31. For example, the center angle corresponding to the third sliding groove 61 is 90°.

In some embodiments, the sliding distance of the second connecting member 32 defined by the limiting structure 5 in the first connecting member 31 is 2 mm-10 mm.
