[0024] Specifically, similar to other glasses, the lead glasses in this embodiment also include two mirror-symmetrically arranged glasses units 1, each of which includes a frame 2, a frame 3 and a nose pad 9. In order to adjust the distance between the two glasses units 1 (i.e., to adjust the pupil distance), a distance adjustment mechanism 5 is provided between the two glasses units 1 in this embodiment. Figure 2 As shown, the spacing adjustment mechanism 5 includes an adjustment rod 11, a guide slot and an adjustment card 12. In this embodiment, a guide slot is provided on each of the two mirror frames 2, and each guide slot is provided at the top of the mirror frame 2 and extends along the top frame. In this embodiment, the two ends of the adjustment rod 11 are respectively inserted into the corresponding guide slot. In this embodiment, each guide slot has a first opening and a second opening. In this embodiment, the first openings of the two guide slots are arranged relative to each other, and the two ends of the adjustment rod 11 are respectively inserted into the corresponding guide slot through the first opening. In this embodiment, the second opening is provided at the top position of the guide slot. The second opening is extended along the top frame of the mirror frame 2. In this embodiment, the adjustment card 12, i.e., the guide slide is assembled at the second opening position of the guide slot.

[0025] In this embodiment, each adjustment card 12 is provided with a sliding member 14 at the end thereof facing the corresponding frame 3, and a slide groove 15 is provided on the corresponding frame 3, and the slide groove 15 is arranged to extend along the top edge of the frame 2. In this embodiment, the sliding member 14 is rod-shaped, one end of the sliding member 14 is connected and fixed to the adjustment card 12, and the other end is guided and slidably assembled in the slide groove 15. In this embodiment, a second bevel gear mechanism is provided between both ends of the adjustment rod 11 and the corresponding adjustment card 12, and the second bevel gear mechanism includes a first bevel gear portion provided on the adjustment card 12 and a second bevel gear portion provided on the adjustment rod 11, the first bevel gear portion and the second bevel gear portion are meshed and assembled together, and the first bevel gear portion and the second bevel gear portion both include a plurality of inclined convex teeth.

There are two second elastic members 13, and the two second elastic members 13 are respectively connected between the corresponding adjustment cards 12 and the guide slots. When the two adjustment cards 12 are slid outward, the first oblique tooth portion of each adjustment card 12 will separate from the second oblique tooth portion on the corresponding adjustment rod 11. At this time, each adjustment card 12 will pop out from the corresponding second opening of the slot due to the pushing action of the second elastic member 13, and then the length of the adjustment rod 11 between the two frames 2 can be adjusted by pulling the two frames 2. When the adjustment rod 11 is adjusted, the two adjustment cards 12 are pressed into the corresponding second opening again and re-engaged and fixed with the corresponding end of the adjustment rod 11.

In order to enhance the stability of the connection between the two eyeglass units 1, a plug 16 is further provided between the two eyeglass units 1 in this embodiment, one end of the plug 16 is fixed to one frame 2, and a socket for the plug 16 to be inserted is provided on the other frame 2, and the plug 16 can move in the socket, and the blocking effect of the plug 16 and the socket hole wall limits the lateral displacement of the two frames 2, thereby preventing the two frames 2 from easily rotating around the adjustment rod 11. In this embodiment, the adjustment rod 11 is in the shape of a quadrangular prism, and the first opening is also correspondingly a rectangular opening, which can also limit the rotation of the frame 2.

[0027] In this embodiment, a first card slot 6 and a second card slot 7 are provided in both frames 2, and the first card slot 6 is located outside the second card slot 7. In this embodiment, the first card slot 6 is an annular card slot, and the four edges of the lead lens 8 are all clamped in the first card slot 6, so that a gap between the lead lens 8 and the frame 2 can be avoided to cause a radiation protection effect. In this embodiment, the second card slot 7 is an arc card slot, and the second card slot 7 can enclose four-fifths of the length of the myopic lens. The second card slot 7 in each frame 2 is arranged on a side close to the nose pad 9.

One end of the two third elastic members 19 is fixedly connected to the inner bottom surface of the mounting groove 17, and the other end is fixedly connected to the adjustment button 18. The third elastic member 19 can push the adjustment button 18 upward, thereby realizing the meshing assembly of the first helical tooth portion and the second helical tooth portion. In this embodiment, the transmission member 20 is a steel wire. One end of the transmission member 20 is connected and fixed to the adjustment button 18, and the other end extends from the mounting groove 17 and is connected and fixed to the V-shaped member 22. In this embodiment, the V-shaped member 22 is a V-shaped card plate, and the V-shaped member 22 is used to clamp with the edge of the myopic lens.
