[0021] The following will be combined with the attached embodiment of the present utility model Figure 1-4, clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, the utility model discloses a pair of glasses with retractable temples, comprising a frame 1 and temples 2, wherein the temples 2 include a main leg 21 and an auxiliary leg 22, wherein the main leg 21 is used to be connected to the frame 1, and the auxiliary leg 22 is slidably arranged on the main leg 21 as an extension of the main leg 21 forward and backward.

[0024] An elastic arch strip 3 is arranged at the upper end of the temple 2. The elastic arch strip 3 is arched upward and its two ends are respectively hinged to the main leg 21 and the auxiliary leg 22. At the same time, an elastic arch strip flattening mechanism is arranged on the temple 2.

[0025] The elastic arch strip flattening mechanism specifically includes a snap-in component, which includes a rod portion 23 and a plug 24 fixedly arranged at the upper end of the rod portion 23. Correspondingly, a slot 31 for the snap-in component to be engaged is provided on the elastic arch strip 3. In this structure, when the elastic arch strip 3 is pressed downward, the plug 24 can be squeezed into the slot 31 and pass through the slot 31 and abut against the upper end of the elastic arch strip 3, so that the elastic arch strip 3 is flattened. After the elastic arch strip 3 is flattened, since the two ends of the elastic arch strip 3 are separated from each other, the main leg 21 and the auxiliary leg 22 connected to the end of the elastic arch strip 3 will be separated from each other, and the total length of the temple 2 is extended. When the elastic arch strip 3 is pulled upward to a state separated from the plug 24, the elastic arch strip 3 is arched again, and the total length of the temple 2 is shortened.

[0026] In order to facilitate the plug 24 to squeeze into and pass through the slot 31 , a deformation slit 32 is further provided on the side wall of the slot 31 .

[0027] A slide groove 211 is provided at the rear end of the main leg 21 , and a slide rod 221 for sliding in the slide groove 211 is fixedly provided at the front end of the auxiliary leg 22 . A length retaining mechanism for fixing the slide rod 221 is provided in the slide groove 211 .

[0028] Furthermore, a sliding cavity 212 is provided on the side wall of the slide groove 211, and the sliding cavity 212 is provided with multiple sliding cavities and arranged at intervals along the extension direction of the slide groove 211, and the length maintaining mechanism includes a limit block 213 slidably set in the sliding cavity 212. At the same time, an elastic member 214 is provided in the sliding cavity 212 for pushing the limit block 213 outward, and one end of the limit block 213 passes through the sliding cavity 212 and the end is hemispherical. Correspondingly, a plurality of hemispherical grooves 222 are correspondingly provided on the side wall of the slide rod 221 facing the limit block 213.

[0029] The working principle of this structure is: this structure can assist the clamping part to further fix the length of the temple 2. When the limit block 213 is embedded in the hemispherical groove 222, the limit block 213 can play a certain limiting role on the position of the auxiliary leg 22, thereby generating resistance to the deformation of the elastic arch strip 3.

[0030] In this embodiment, the elastic arch strip 3 is preferably made of titanium alloy among memory alloys, which has the characteristics of good toughness and light weight, is not easy to break, and is helpful to reduce the burden on the wearer's head.

[0031] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
