As another example, as shown in fig. 3 and 4, the first connecting member 31 includes a rigid main body 311 and an elastic material 312 disposed on an inner wall of the main body 311, and the first connecting member 31 applies an elastic gripping force to the second connecting member 32 sleeved therein through the elastic material 312, and the elastic gripping force can prevent the second connecting member 32 from sliding in the first connecting member 31, so as to provide sliding damping to the second connecting member 32 along the height direction of the lens frame 1. The first connecting member 31 has a simple structure and is easy to manufacture.

The elastic material 312 may be disposed on an inner wall of a certain section of the main body 311 in the axial direction, or may be disposed on an inner wall of the main body 311 in the axial direction as a whole, which is not particularly limited herein. In some embodiments, as shown in fig. 4, the elastic material 312 is disposed on an inner wall of a certain section of the main body 311 in the axial direction, so that the coverage area of the elastic material 312 is smaller and the elasticity is larger.

The elastic material 312 may be disposed on an inner wall of a certain section of the circumference of the main body 311, or disposed around the inner wall of the main body 311, which is not limited herein. In some embodiments, as shown in fig. 5 and 6, the elastic material 312 is disposed on the inner wall of a certain section of the main body 311 in the circumferential direction, so that the coverage area of the elastic material 312 is small and the elasticity is large.

In this way, the second connecting piece 32 can be prevented from being separated from the first connecting piece 31 by the limiting structure 5 during the height adjustment process of the nose pad 2.

In the above embodiments, the structure of the limiting structure 5 has various forms, and is not limited in detail here.

Illustratively, the limiting structure 5 includes a slide rail and a slide block, the slide rail extends along the axial direction of the first connecting member 31, the two ends of the slide rail are fixed with stoppers, the slide block is slidably connected to the slide rail, the slide rail is disposed on the first connecting member 31, and the slide block is disposed on the second connecting member 32. Thus, the stoppers at the two ends of the slide rail can stop the slide block to prevent the slide block from separating from the slide rail, so that the second connecting piece 32 is prevented from separating from the first connecting piece 31 in the height adjusting process of the nose pad 2. Wherein, the slide rail is a horse-riding type 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, two ends of the first sliding groove 51 are closed, the sliding member 52 is in sliding fit 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. In this way, the two ends of the first sliding groove 51 can stop the sliding part 52, and the sliding part 52 is prevented from being separated from the first sliding groove 51, so that the second connecting part 32 is prevented from being separated from the first connecting part 31 during the height adjustment process of the nose pad 2.

As shown in fig. 8, the sliding member 52 may be a block structure, a column structure, a roller structure, etc., and is not limited in particular. In some embodiments, the slide 52 is a roller. As described above, when sliding along first runner 51, the friction between slider 52 and the side wall of first runner 51 is rolling friction, and the friction force during rolling friction is small, so that the purpose of reducing wear can be achieved.

In some embodiments, as shown in fig. 7, the first sliding groove 51 is disposed on the inner wall of the first connecting member 31, as shown in fig. 8, the sliding member 52 is disposed on the second connecting member 32; as shown in fig. 7, the inner wall of the first connecting member 31 is further provided with a second sliding groove 6, the extending direction of the second sliding groove 6 is different from the extending direction of the first sliding groove 51, one end of the second sliding groove 6 is communicated with the first sliding groove 51, the other end of the second sliding groove 6 penetrates through 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, so as to separate the second connecting member 32 from the first connecting member 31. Thus, by separating the second connecting member 32 from the first connecting member 31, the nose pad 2 can be detached from the eyeglass frame 1 to repair or replace the nose pad 2, thereby reducing the maintenance cost of the eyeglasses.

In the above embodiment, the second slide groove 6 may communicate with an end portion of the first slide groove 51, and may also communicate with a middle portion of the first slide groove 51, and is not particularly limited herein. In some embodiments, as shown in fig. 7, the second chute 6 communicates with an end of the first chute 51. Like this, only need drive second connecting piece 32 and slide in first connecting piece 31 to make slider 52 slide to the tip of first spout 51, can get into the dismantlement process, need not to look for the position that is linked together with second spout 6 on the first spout 51 repeatedly, thereby can simplify the separation process between second connecting piece 32 and the first connecting piece 31, reduce the nose and hold in the palm 2 by the dismantlement degree of difficulty on the picture frame 1.

The second sliding groove 6 may extend in a spiral shape around the inner wall of the first connecting member 31, or may extend in a serpentine shape, which is not limited herein, as long as the extending direction of the second sliding groove 6 is different from the extending direction of the first sliding groove 51, so as to prevent the sliding member 52 from 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 preventing the second connecting member 32 from being separated from the first connecting member 31 during the height adjustment process of the nose pad 2.

Thus, the process of detaching the nose pad 2 from the frame 1 can be as follows: the second connecting member 32 is first driven to slide in the first connecting member 31, so that the sliding member 52 moves to a position where the second sliding groove 6 is communicated with the first sliding groove 51, then the second connecting member 32 is rotated relative to the first connecting member 31, so that the sliding member 52 slides along the third sliding groove 61 to an end of the third sliding groove 61 away from the first sliding groove 51, and finally the second connecting member 32 is driven to slide in the first connecting member 31 again, so that the sliding member 52 slides along the fourth sliding groove 62 to an end of the fourth sliding groove 62 penetrating through the end surface of the first connecting member 31, and slides out from an end of the fourth sliding groove 62 penetrating through the end surface of the first connecting member 31.

In some embodiments, the third sliding groove 61 has a central angle of 70 ° to 110 °. In this way, the length of the third sliding groove 61 is moderate, so that the possibility that the sliding member 52 is out of the first sliding groove 51 due to the excessively short length of the third sliding groove 61 can be avoided, and the operation difficulty of separation and installation between the second connecting member 32 and the first connecting member 31 due to the excessively long length of the third sliding groove 61 can be avoided. Illustratively, the third sliding groove 61 corresponds to a central angle of 90 °.
