[0022] The utility model will be further explained in detail in connection with the drawings.

[0023] The embodiment discloses detachable glasses with lenses, like Figures 1-5 As shown in the drawings, the glasses comprise lenses 1 and a frame 2, the lenses 1 comprise lens parts 101 on both sides and a connecting part 102 in the middle, the middle part of the frame 2 is provided with a connecting groove 3, the connecting groove 3 is provided with a deformable snap spring structure 4, preferably a metal material with reset elasticity, and has a long service life. The connecting part 102 is provided with a clamping notch 5, the clamping notch 5 is clamped and matched with the snap spring structure 4 to realize detachable connection of the lenses 1 and the frame 2. Referring to Figure 1 and Figure 2 Through the above structure, the connecting groove 3 is directly arranged on the frame 2, and the clamping notch 5 is arranged on the lens 1, and the installation and disassembly can be completed by means of downward pressing and upward pulling (ejection), which is very convenient in operation, and the structure is very simple, the production cost is effectively controlled, and the practical value is high. Meanwhile, the embodiment can also be a single-sided glasses, the lenses only need to retain the connecting part 102 and the lens part 101 on the corresponding side, and the frame 2 retains the connecting groove 3 and the frame on the corresponding side.

[0024] Further referring to Figure 2 The middle part of the frame 2 is protruded to the side away from the frame 2 and is provided with a baffle 6, the connecting groove 3 is formed between the baffle 6 and the frame 2, the baffle 6 can limit the lens 1, and meanwhile, the baffle 6 can shield the snap spring structure 4 in the connecting groove 3 and the clamping notch 5 on the lens 1, so that the overall appearance of the glasses is more integral and more beautiful after installation.

[0025] Further, the groove width of the connecting groove 3 is matched with the thickness of the connecting part 102, and through the above structure, the connecting part 102 is clamped into the connecting groove 3 to form stable cooperation.

[0026] Further, referring to Figures 3-4 The snap spring structure 4 comprises a guide segment 401 and a clamping segment 402, the guide segment 401 is arranged in an inverted V-shaped structure extending to both sides from top to bottom, the clamping segment 402 is connected to the guide segment 401 and converges to the middle from top to bottom, and a clamping point 7 is formed at the joint of the guide segment 401 and the clamping segment 402. Meanwhile, the internal notch shape of the clamping notch 5 is the same as that of the snap spring structure 4. The upward and downward directions are the upward and downward directions when the user wears the glasses, and thus through the above structure, when the lens 1 is pressed downward, due to the inclined surface structure of the guide segment 401, the snap spring structure 4, especially the clamping point 7, is compressed to deform inward, so that the snap spring structure 4 smoothly enters the clamping notch 5, and further referring to Figure 5When the clamping spring structure 4 is completely inserted, the clamping spring structure 4 is reset, and the clamping points 7 are reset to the outside, thereby forming a clamping fit with the clamping notches 5; when disassembling, the lens 1 can be pulled out upward or pushed out from below, and since the clamping spring structure also has a clamping section 402, which is a structure that is folded inward, when moving from below to above, the inclined surface structure of the clamping section 402 will also deform the clamping points 7 inward, thereby allowing the clamping notches 5 and the clamping spring structure 4 to be smoothly separated.

[0027] Further referring to Figure 5 As a preferred embodiment, since the clamping spring structure 4 has elastic reset performance and has low strength when subjected to a lateral force, a positioning protrusion 301 is arranged at the bottom of the connecting groove 3, and a stepped portion 501 is arranged at the notch edge of the clamping notch 5, and the stepped portion 501 is matched with the positioning protrusion 301. Through the above structure, the stepped portion 501 and the positioning protrusion 301 are matched to strengthen the stability of the lens 1 when subjected to a lateral load, thereby ensuring that the lens 1 will not fall off during various activities such as running and jumping of the wearer, and the structure is stable.

[0028] Further, the lens 1 of the embodiment includes but is not limited to various resin lenses and PC lenses, as long as the clamping notches 5 can be processed, and is preferably manufactured in an integrated manner.

[0029] Further, in order to ensure the wearing of the glasses, the frame 2 of the embodiment is provided with a temple and a nose pad, the temple is hingedly connected with the frame 2, and the temple and the nose pad are the same as the prior art, and are not shown in the figure.

[0030] The above only describes the preferred embodiment of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. within the design concept of the present application shall be included in the protection scope of the present application.
