[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the implementation mode of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to the accompanying drawings, in an embodiment of this implementation mode, the lens connection structure of the frameless glasses includes a lens 1 and a temple 2. The part of the lens 1 near the edge is connected to the temple 2. A first limiting hole 10 that penetrates through from front to back is provided at the part of the lens 1 near the edge. Generally, the first limiting hole 10 is provided at the outer edge of the lens 1 (that is, the outer side of the left lens 1 is the left side, and the outer side of the right lens 1 is the right side). A lens extension protrusion can be provided at the outer edge position of the lens 1 for the first limiting hole 10 to be provided, and the visual field range of the lens 1 is relatively larger; a first limiting block 20 is provided at the front end of the temple 2, and the first limiting block 20 is fitted and installed in the first limiting hole 10. Among them, the first limiting block 20 can be inserted into the corresponding first limiting hole 10 from back to front. A part of the temple 2 can be blocked by the lens 1 in terms of visual perception. The cooperation and limiting connection between the first limiting block 20 and the first limiting hole 10 on the lens 1 make the relative position between the temple 2 and the lens 1 in a stable state, not easy to loosen or rotate; in addition, a first side pin hole 11 is also provided at the side part of the lens 1. The first side pin hole 11 is located on the lens body between the front mirror surface 15 and the rear mirror surface 16 of the lens 1, that is, the first side pin hole 11 is opened on the thickness surface of the lens 1. The first side pin hole 11 communicates with the first limiting hole 10. A first pin 111 is fitted and installed in the first side pin hole 11. The first pin 111 can be inserted into the first side pin hole 11 and can extend into the first limiting hole 10 to cooperate with the first limiting block 20. Among them, a first locking port 21 is provided on the side of the first limiting block 20 facing the first side pin hole 11. The first locking end at the end of the first pin 111 is fitted and extends into the first locking port 21, thereby locking the first pin 111 with the first limiting block 20 on the temple 2 and preventing the first limiting block 20 from moving back and forth out of position. In this connection structure, that is, the connection structure between the temple 2 and the lens, when the first limiting block 20 on the temple 2 is assembled with the first limiting hole 10 on the lens 1, it only needs to be inserted from back to front and then locked by the first pin 111 on the side. The positions of the lens 1 and the temple 2 are not easy to loosen from each other, and the assembly operation is relatively convenient. Moreover, the first limiting hole 10 is a through hole that penetrates through from front to back and can integrally match the thickness of the lens 1. The thicknesses of lenses 1 with different degrees can all be integrally matched and filled in the first limiting hole 10 by the first limiting block 20, making the lens 1 not easy to break.

[0028] Referring to the accompanying drawings, in another embodiment of the present embodiment, the lens connection structure of the frameless glasses includes a lens 1 and a nasal bridge 3. The portion of the lens 1 near the edge is connected to the nasal bridge 3. A second limiting hole 12 penetrating through the front and back is provided at the portion of the lens 1 near the edge, generally on the inner edge of the lens 1 (i.e., the inner side of the left lens 1 is the right side, and the outer side of the right lens 1 is the left side) to set the second limiting hole 12; a second limiting block 30 is provided on the nasal bridge 3, and the second limiting block 30 is fitted and installed in the second limiting hole 12. The second limiting block 30 can be inserted into the corresponding second limiting hole 12 from the back to the front. The two side regions of the nasal bridge 3 can be partially blocked by the lens 1 in the visual sense. The cooperation and limiting connection between the second limiting block 30 and the second limiting hole 12 on the lens 1 keep the relative position between the nasal bridge 3 and the lens 1 in a stable state, not easy to loosen or rotate; in addition, a second side pin hole 13 is also provided at the side portion of the lens 1. The second side pin hole 13 is located on the lens body between the front mirror surface 15 and the rear mirror surface 16 of the lens 1, that is, the second side pin hole 13 is opened on the thickness surface of the lens 1. The second side pin hole 13 is communicated with the second limiting hole 12. A second pin 131 is fitted and installed in the second side pin hole 13. The second pin 131 can be inserted into the second side pin hole 13 and extend into the second limiting hole 12 to cooperate with the second limiting block 30. A second locking port 31 is provided on the side of the second limiting block 30 facing the second side pin hole 13. The second locking end at the end of the second pin 131 is fitted and extends into the second locking port 31, thereby locking the second pin 131 with the second limiting block 30 on the nasal bridge 3 and preventing the second limiting block 30 from moving forward and backward out of position. In this connection structure, that is, the nasal bridge 3 and the lens connection structure, when the second limiting block 30 on the nasal bridge 3 is assembled with the second limiting hole 12 on the lens 1, only need to insert from the back to the front and then lock it with the second pin 131 on the side. The positions of the lens 1 and the nasal bridge 3 are not easy to loosen, and the assembly operation is relatively convenient. Moreover, the second limiting hole 12 is a through hole penetrating through the front and back, which can match the thickness of the lens 1 as a whole. The thicknesses of lenses 1 with different degrees can be integrally matched and filled in the second limiting hole 12 by the second limiting block 30, making the lens 1 not easy to break.

[0029] Based on the above embodiments, the following optimizations or further explanations can be made respectively.

[0030] For example, the corresponding limit holes adopt anti-rotation holes, that is, the first limit hole 10 and the second limit hole 12 can adopt anti-rotation holes. When the first limit block 20 is inserted into the first limit hole 10, it will not rotate, preventing the pile head 2 from rotating relative to the lens 1; when the second limit block 30 is inserted into the second limit hole 12, it will not rotate, preventing the nose bridge 3 from rotating relative to the lens 1. For example, the corresponding limit holes (i.e., the first limit hole 10 and the second limit hole 12) can adopt anti-rotation structures in the shape of oval holes, square holes, rectangular holes, etc. The corresponding first limit block 20 and second limit block 30 are respectively an oval block, a square block or a rectangular block. The second limit block 30 is located on the left and right sides of the nose bridge 3. The pile head 2 can also be in contact with the rear mirror surface 16 of the lens 1, and the nose bridge 3 is in contact with the rear mirror surface 16 of the lens 1, which increases stability and ensures smooth installation of the limit block from the back to the front. The pile head 2 and the first limit block 20 can adopt an integral structure or a split connection structure. Similarly, the nose bridge 3 and the second limit block 30 can adopt an integral structure or a split connection structure.

[0031] In addition, it can be further optimized that the front side surface of the corresponding limit block is coplanar with the front mirror surface 15 of the lens 1 at the corresponding limit hole, that is, the front side surface of the first limit block 20 is coplanar with the front mirror surface 15 of the lens 1 at the first limit hole 10, and the front side surface of the second limit block 30 is coplanar with the front mirror surface 15 of the lens 1 at the second limit hole 12. In the case of setting the limit holes, after being filled by the limit blocks, the front mirror surface 15 of the lens 1 is relatively complete, without the visual effect of obvious holes. The limit block and the front side of the lens 1 form a relatively complete surface, which is not easy to scratch and not easy to leave dirt.

[0032] For example, the corresponding pins adopt cylindrical pins. That is, the first pin 111 and the second pin 131 can adopt cylindrical pins, which are convenient for processing. The corresponding pins (i.e., the first pin 111 and the second pin 131) adopt metal pins (such as titanium metal, copper, silver and alloys, etc.) or plastic pins. The corresponding pins (i.e., the first pin 111 and the second pin 131) can also adopt transparent pins, such as transparent nylon pins.

[0033] Among them, the corresponding limit blocks (i.e., the first limit block 20 and the second limit block 30) are inserted into the corresponding limit holes (i.e., the first limit hole 10 and the second limit hole 12) from the back to the front.

[0034] In addition, the corresponding locking openings (i.e., the first locking opening 21 and the second locking opening 31) adopt locking groove openings that penetrate up and down or the corresponding locking openings adopt lateral locking holes, which are convenient for processing and manufacturing.
