[0020] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0022] The specific implementation methods of the present application will be further described below in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] The present application embodiment discloses a lens connector for frameless glasses, referring to Figure 1 and Figure 2 As shown, it includes a connector body 1, and lens 4 mounting seats 11 are respectively provided at both ends of the connector body 1, and a plug-in portion 12 is provided on one side of the lens 4 mounting seat 11. Two plug-in portions 12 are provided, and the two plug-in portions 12 are symmetrical to each other. Trapezoidal grooves 2 are formed on the inner edges of the two plug-in portions 12, and inverted tooth portions 3 are provided on the outer edges of the plug-in portions 12. The two plug-in portions 12 are used to fasten and adapt to the rectangular hole 41 on the lens 4. The connector body 1 can be manufactured by wire cutting or stamping. The plug-in portion 12 can be inserted into the rectangular hole 41, and it is relatively easy to open the rectangular hole 41 on the lens 4. At this time, the assembly method is also relatively simple, and it can be directly plugged in. No screws or glue are required for fixing, which is a feature of the present application.

[0025] In order to fix more effectively, the outer edge of the plug-in portion 12 is optionally provided with an arc edge 121, the end of the arc edge 121 reaches the inverted tooth portion 3, and the inverted tooth portion 3 has a bevel 31 and a tooth groove 32 that appear alternately. The arc edge 121 has a guiding function, and it is easier to calibrate the rectangular hole 41 during assembly. Then, the structure of the inverted tooth portion 3 is that the installation is more labor-saving, and the disassembly will be difficult to detach the lens 4 due to the resistance of the inverted teeth, thereby improving the reliability of the installation of the lens 4. In addition, a mounting method can be provided, in which the rectangular hole 41 of the lens 4 is firstly placed opposite the plug-in portion 12, and then the lens 4 is continuously swung to clamp the lens 4 into the plug-in portion 12.

[0026] In addition, optionally, the lens 4 mounting seat 11 is provided with a support ear portion 111, and the support ear portion 111 forms a 60-100 degree angle groove 112 with the plug-in portion 12. This structure is used to limit the plug-in degree of the lens 4 and the plug-in portion 12, so that the lens 4 is installed in a reliable clamping position.

[0027] Embodiment 2:

[0028] Based on the structure of the first embodiment, it can be seen that the two plug-in parts 12 can be further staggered up and down. Figure 3 As shown, the two plug-in parts 12 are respectively provided with chamfered surfaces 5, and the plug-in parts 12 are mutually displaced by the chamfered surfaces 5, and the thickness is increased. It is known that when the two plug-in parts 12 are simultaneously inserted into the rectangular hole 41, the two plug-in parts 12 will be forced to squeeze each other, and although the trapezoidal groove 2 provides a deformation activity space, in order to further achieve fastening, the above-mentioned chamfered surfaces 5 are used for guidance, so that the two plug-in parts 12 are partially displaced up and down, and then the thickness is superimposed on each other, so that a conflict is formed on the upper and lower inner walls of the rectangular groove, and the fastening ability is further improved.

[0029] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
