[0021] The following is a combination of the appended examples of the present invention Figure 1-6 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] As shown in the figure, it includes a lens ring 1, a center beam 2, a stud 3, temples 4, a lens 5 and a nylon thread 6. The lens 5 is arranged in the lens ring 1, and the temples 4 are hinged on the stud 3. The lens ring 1 is composed of a fixed part 11 and a disassembly part 12. The inner and outer ends of the fixed part 11 are fixedly connected to the center beam 2 and the stud 3 respectively. One end of the nylon thread 6 is fixedly connected to the inner end of the fixed part 11, and the other end is fixedly connected to the disassembly part 12. The disassembly part 12 is fixedly connected to the stud 3 by a fastening bolt 13 and is located on the side of the outer end of the fixed part 11 and is spliced ​​with the fixed part 11, so that the nylon thread 6 is buckled into the wire groove opened on the side surface of the lens 5.

[0023] Specifically, the disassembly part 12 is fixedly connected to the fixed part 11 by a fastening bolt 13: a polygonal column-shaped plug-in pile 121 is formed on the disassembly part 12, and a plug-in hole 31 matching the plug-in pile 121 is provided on the pile head 3. The plug-in pile 121 is inserted into the plug-in hole 31, and the fastening bolt 13 is screwed into the plug-in pile 121 and tightly abuts against the end of the plug-in hole 31, thereby realizing a fixed connection between the disassembly part 12 and the pile head 3.

[0024] In the above structure, the two ends of the nylon thread 6 are respectively fixed to the fixing part 11 and the disassembling part 12. The disassembling part 12 is fixedly connected to the fixing part 11 and the nylon thread 6 is tightened so that the nylon thread 6 is tightly buckled in the wire groove provided on the side surface of the lens 5 to fix the lens 5. When the lens 5 needs to be cleaned, the fastening bolt 13 is unscrewed and the plugging pile 121 is pulled out from the plug hole 31 to separate the disassembling part 12 from the fixing part 11, and the nylon thread 6 is separated from the wire groove of the lens 5. At this time, the lens 5 can be easily removed for cleaning. When installing the lens 5, the lens 5 is placed in the fixing part 11 so that the positioning protrusion 122 on the side surface of the lens 5 is stuck in the positioning groove on the inner side of the fixing part 11. Then the nylon thread 6 is buckled into the wire groove of the lens 5 and the plugging pile 121 is pulled out from the plug hole 31. The pile 121 is inserted into the plug hole 31 to connect the disassembly part 12 with the fixed part 11. The multi-prism-shaped plug pile 121 cooperates with the plug hole 31 to limit the rotation of the disassembly part 12 relative to the fixed part 11, thereby ensuring the stability of the disassembly part 12 after being connected to the fixed part 11. Then, the fastening bolt 13 is tightened, and the fastening bolt 13 tightens the fixed part 11 and the disassembly part 12 to achieve a fixed connection between the disassembly part 12 and the fixed part 11. At this time, the nylon wire 6 is tightened in the wire groove of the lens 5 to fix the lens 5 and realize the installation of the lens 5. It can be seen that the above structure and the disassembly and assembly method of the lens 5 can realize the disassembly and assembly of the lens 5 only by disassembling the fastening bolt 13. The operation is relatively simple and ordinary users can complete the operation at home, thereby facilitating the maintenance of glasses during daily wear. Of course, in the above structure, in addition to limiting the relative rotation of the disassembly part 12 and the fixing part 11 by cooperating with the plug-in post 121 and the plug-in hole 31, it can also be achieved by setting multiple fastening bolts 13. However, when disassembling and assembling the lens 5, the disassembly and assembly of multiple screws will be involved. Compared with the above embodiment in which the plug-in post 121 cooperates with the plug-in hole 31 and only one fastening bolt 13 is required, the operation is more cumbersome. Therefore, the cooperation between the plug-in post 121 and the plug-in hole 31 further facilitates the operation of disassembling and assembling the lens 5 on the basis of allowing ordinary users to disassemble and assemble the lens 5 by disassembling and assembling the fastening bolt 13.

[0025] In addition, a plurality of positioning protrusions 122 are formed on the end surface of the disassembly portion 12 facing the fixed portion 11, and a positioning hole 111 is provided on the end surface of the fixed portion 11 to match and correspond to the plurality of positioning protrusions 122. When the disassembly portion 12 is fixedly connected to the pile head 3, the positioning protrusions 122 are retained in the positioning holes 111. When the plug pile 121 is inserted into the plug hole 31 to connect the disassembly portion 12 with the fixed portion 11, the positioning protrusions 122 and the positioning holes 111 are aligned. The cooperation provides a positioning function for the assembly and disassembly portion 12 and the fixing portion 11, avoiding the problem of deviation between the assembly and disassembly portion 12 and the fixing portion 11 due to incorrect orientation during operation, thereby further facilitating the operation of disassembling and assembling the lens 5. Moreover, after the assembly and disassembly portion 12 is fixedly connected to the fixing portion 11, the positioning protrusion 122 cooperates with the positioning hole 111 to limit the relative rotation of the assembly and disassembly portion 12 and the fixing portion 11, thereby enhancing the stability of the assembly and disassembly portion 12 and the fixing portion 11 after being fixedly connected.

[0026] In addition, the disassembly portion 12 is in the shape of a figure 7, the plug-in pile 121 is formed on the horizontal part of the disassembly portion 12, the nylon wire 6 is fixedly connected to the vertical part of the disassembly portion 12, and the pile head 3 is formed with a limiting groove 32 located on one side of the end of the horizontal part of the disassembly portion 12 and matching. When the disassembly portion 12 is fixedly connected to the pile head 3, the end of the horizontal part of the disassembly portion 12 is maintained in the limiting groove 32, and the relative rotation of the disassembly portion 12 and the fixed portion 11 is limited, thereby enhancing the stability of the disassembly portion 12 and the fixed portion 11 after being fixedly connected.

[0027] In addition, two spaced-apart threading holes 123 are provided on the vertical portion of the disassembly and assembly part 12, and a first wire pressing groove 124 is provided on the end face of the horizontal flat portion of the disassembly and assembly part 12, which passes through the disassembly and assembly part 12 toward the inner side of the disassembly and assembly part 12, and a second wire pressing groove 33 is provided on the pile head 3, and the end of the nylon thread 6 passes through the two threading holes 123 in turn and is placed between the first wire pressing groove 124 and the second wire pressing groove 33. When the disassembly and assembly part 12 is fixedly connected to the pile head 3, the first wire pressing groove 124 cooperates with the second wire pressing groove 33 to clamp the end of the nylon thread 6. The first wire pressing groove 124 and the second wire pressing groove 33 cooperate to clamp the end of the nylon thread 6, so that the end of the nylon thread 6 is more firmly connected to the disassembly and assembly part 12, so that the nylon thread 6 is stably kept expanded in the wire groove of the glasses, thereby improving the stability of the lens 5 installed on the lens ring 1.

[0028] In addition, a first threading groove 125 is provided on the horizontal portion of the disassembly and assembly portion 12, which is connected to the first wire pressing groove 124 and passes through the disassembly and assembly portion 12 backward. A second threading groove 34 is provided on the pile head 3, which is opposite to the first wire pressing groove 124. When the nylon thread 6 needs to be replaced, before the tightening bolt 13 is completely tightened, that is, before the nylon thread 6 is tightened, the end of the nylon thread 6 is passed between the first wire pressing groove 124 and the second wire pressing groove 33, and then through the first threading groove 125 and the second threading groove 34 to pass through the lens ring 1. By pulling the part of the nylon thread 6 that passes through the lens ring 1, the nylon thread 6 is tightened while tightening the tightening bolt 13, and it is kept tight after the tightening bolt 13 is tightened. Then, the nylon thread 6 exposed in the lens ring 1 can be cut off, thereby facilitating the operation of replacing the nylon thread 6 and adjusting the tightness of the nylon thread 6.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
