The number of eyeglass frames is two sets, and a connecting nose pad is provided between the two sets of eyeglass frames. The two sets of eyeglass frames are connected by the connecting nose pad.

[0006] There are two sets of lenses, each mounted on one of the two sets of eyeglass frames;

[0007] The strip-shaped limiting post is equipped with a movable limiting plate, which is used to limit the strip-shaped limiting post to the eyeglass frame.

[0008] Preferably, the eyeglass frame has an opening inside for the movement of the lens, and the lens is located inside the opening.

[0009] Preferably, a strip-shaped limiting plate is fixedly installed on one inner wall of the eyeglass frame, and there are three sets of strip-shaped limiting plates, with the eyeglass lens located between two sets of strip-shaped limiting plates.

[0010] Preferably, an opening is provided on one side of the inner wall of the eyeglass frame, and a limiting opening is provided at the top of the opening.

[0011] Preferably, the strip-shaped limiting post is slidably installed in the opening on the eyeglass frame, and a movable strip-shaped limiting plate is fixedly installed on one side of the strip-shaped limiting post, with the eyeglass lens located between another set of strip-shaped limiting plates and the movable strip-shaped limiting plate.

[0012] Preferably, the strip-shaped limiting post has an internal movable groove, a return spring is fixedly installed at the bottom of the inner side of the movable groove, a sliding cross plate is fixedly installed at the top of the return spring, a movable limiting plate is fixedly installed at the top of the sliding cross plate, one end of the movable limiting plate extends into the limiting opening, and a sliding top plate is fixedly installed on one side of the sliding cross plate.

[0013] Preferably, one side of the sliding top plate extends to one side of the strip-shaped limiting post, and the strip-shaped limiting post has an opening that allows the sliding top plate to move.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This eyeglass lens changing structure, through the setting of the strip-shaped limiting post and the movable limiting plate, can install the movable strip-shaped limiting plate on the eyeglass frame, thus allowing the eyeglass lens to be installed on the eyeglass frame. This installation method not only facilitates operation for the user, reduces the time for changing eyeglass lenses, and improves the efficiency of changing eyeglass lenses, but also allows the eyeglass lens to be tightly fixed after changing the lens, improving the stability of the fixed eyeglass lens, thereby increasing the practicality of the device.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Please refer to Figures 1-4. This utility model provides a technical solution: a lens-changing structure for eyeglasses, including an eyeglass frame 1, eyeglass lenses 3, and a strip-shaped limiting post 6. There are two sets of eyeglass frames 1, and a connecting nose pad 2 is provided between the two sets of eyeglass frames 1. The two sets of eyeglass frames 1 are connected by the connecting nose pad 2. There are two sets of eyeglass lenses 3, which are respectively provided on the two sets of eyeglass frames 1. A movable limiting plate 9 is provided on the strip-shaped limiting post 6, which is used to limit the strip-shaped limiting post 6 to the eyeglass frame 1.

[0023] Furthermore, the eyeglass frame 1 has an opening inside for the lens 3 to move. The lens 3 is located within the opening. Three sets of strip-shaped limiting plates 4 are fixedly installed on one inner wall of the eyeglass frame 1. The lens 3 is located between two sets of strip-shaped limiting plates 4. An opening is also provided on one inner wall of the eyeglass frame 1, with a limiting port at the top. A strip-shaped limiting post 6 is slidably installed within the opening on the eyeglass frame 1. A movable strip-shaped limiting plate 10 is fixedly installed on one side of the strip-shaped limiting post 6. The lens 3 is located between another set of strip-shaped limiting plates 4 and the movable strip-shaped limiting plate 10. A movable groove is provided inside the strip-shaped limiting post 6. A return spring 7 is fixedly installed at the bottom inner side of the movable groove, and a sliding crossbar is fixedly installed at the top of the return spring 7. A movable limiting plate 9 is fixedly installed on the top of the sliding horizontal plate 8. One end of the movable limiting plate 9 extends into the limiting opening. A sliding top plate 5 is fixedly installed on one side of the sliding horizontal plate 8. One side of the sliding top plate 5 extends to one side of the strip limiting post 6, and the strip limiting post 6 has an opening for the sliding top plate 5 to move. This arrangement allows the movable strip limiting plate 10 to be installed on the eyeglass frame 1, and the eyeglass lens 3 to be installed on the eyeglass frame 1. This installation method not only facilitates the user's operation and reduces the time for changing the eyeglass lens 3, but also improves the efficiency of changing the eyeglass lens 3. After changing the eyeglass lens 3, it can be tightly fixed, improving the stability of the eyeglass lens 3 after fixing, thereby increasing the practicality of the device.

[0024] Working principle: When changing lenses, first place one side of the lens 3 between the two sets of strip limiting plates 4 to limit one set of the lens 3. Then, lay the lens 3 flat and block it with the other set of strip limiting plates 4. Then, move the sliding top plate 5. The movement of the sliding top plate 5 drives the sliding horizontal plate 8 and the movable limiting plate 9 to move. Then, insert the strip limiting post 6 into the opening on the eyeglass frame 1. After releasing the sliding top plate 5, the return spring 7 rebounds and inserts the movable limiting plate 9 into the limiting port. The other side of the lens 3 is then limited by the movable strip limiting plate 10 and the other set of strip limiting plates 4.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
