[0003] In the structure of glasses, the temples and the studs are usually hinged by screws. However, the hinge formed by the screws means that the internal elasticity of the temples after buckling is only provided by the temples made of elastic material, and the internal elasticity effect is poor. This makes the glasses extremely easy to be damaged when dropped or impacted by objects. Based on this, a new solution is urgently needed to solve the above problem. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] The utility model provides a screwless glasses leg, such as Figures 1 to 5 As shown, it includes: a temple 1 and a head 2, one end of the head 2 is fixedly connected to the lens ring, and the other end is hinged to the temple 1. The embodiment of the utility model only improves the hinge structure between the head 2 and the temple 1. Therefore, the utility model does not describe the method of fixed connection between the head 2 and the lens ring.

[0025] The first end of the temple 1 is provided with a slit 13 extending from the first end toward the second end. The slit 13 separates the portion of the temple 1 close to the first end into two branch structures 14. Both branch structures 14 are provided with a rotating shaft. The two rotating shafts are parallel and the distance between the two rotating shafts is a when not under force. The two ends of the rotating shaft protrude from both sides of the branch structure 14.

[0026] The hinged part of the pile head 2 and the temple 1 is two oppositely arranged connecting plates 23, and a first slide 21 and a second slide 22 are provided on the two connecting plates 23. The two rotating shafts are the first rotating shaft 11 and the second rotating shaft 12. The two ends of the first rotating shaft 11 respectively extend into the first slide 21 on the two connecting plates 23 and can rotate and move in the first slide 21, and the two ends of the second rotating shaft 12 respectively extend into the second slide 22 on the two connecting plates 23 and can rotate and move in the second slide 22; the distance between the first end of the first slide 21 and the second end of the second slide 22 is a, and there is a buckling portion between the first end and the second end of the first slide 21, and the distance between the first end and the buckling portion of the second slide 22 is a, and the slide between the buckling portion and the second end of the first slide 21 extends from the buckling portion toward and / or away from the first end of the second slide 22.

[0027] During implementation, after the temple 1 is buckled, under normal conditions, the first rotating shaft 11 moves to the buckling part of the first slide 21, and the second rotating shaft 12 moves to the first end. When the temple 1 is subjected to pressure or impact force toward the inside, the first rotating shaft 11 continues to move toward the second end of the first slide 21, and since the position of the second rotating shaft 12 will not change, when the first rotating shaft 11 moves, it is necessary to overcome a certain elastic force and make the two branch structures 14 move closer. Therefore, the structural improvement of the screwless glasses temple provided by the utility model improves the internal elasticity of the temple 1 after being buckled, thereby increasing its buffering effect against pressure or impact force.

[0028] In some embodiments, the temple 1 is made of an elastic material, such as various elastic metals, and the temple 1 is integrally formed.

[0029] This embodiment can further improve the internal elasticity of the temple 1, thereby further improving the service life and safety of the glasses.

[0030] In the above embodiment, the slideway between the buckling portion and the second end of the first slideway 21 extends from the buckling portion toward and / or away from the first end of the second slideway 22. It can be understood that there are the following three implementations:

[0031] In the first embodiment, the slideway between the second ends of the first slideway 21 extends from the locking portion toward the first end of the second slideway 22. In this embodiment, when the first rotating shaft 11 moves from the locking portion toward the second end, the two branch structures 14 move closer. After the external force disappears, the two branch structures 14 rebound and separate, and the first rotating shaft 11 returns to the locking portion.

[0032] In the second embodiment, the slideway between the locking portion and the second end of the first slideway 21 extends from the locking portion toward the first end of the second slideway 22. In this embodiment, as the first rotating shaft 11 moves from the locking portion toward the second end, the two branch structures 14 separate, increasing the gap 13 between them. After the external force disappears, the two branch structures 14 rebound and move closer together, at which point the first rotating shaft 11 returns to the locking portion.

[0033] Third, the slideway between the locking portion and the second end of the first slideway 21 extends from the locking portion toward and away from the first end of the second slideway 22. In this embodiment, the distance between the second end of the first slideway 21 and the first end of the second slideway 22 can be set to a value a. With this arrangement, after the first rotating shaft 11 moves from the locking portion to the second end and the external force disappears, the first rotating shaft 11 will remain at the second end and will not return to the locking portion.

[0034] In some embodiments, the second slideway 22 is an oblong hole, and the diameter of the arc profiles at both ends of the second slideway 22 is the same as the diameter of the second rotating shaft 12 . The diameter of the arc profiles at both ends of the first slideway 21 is the same as the diameter of the first rotating shaft 11 .

[0035] In some embodiments, such as Figure 3 As shown, the wall surface of the first slideway 21 away from the second slideway 22 is recessed in a direction away from the second slideway 22 and has a smooth transition to form a guide surface to guide the first rotating shaft.

[0036] In some embodiments, the connecting plate 23 is a square plate.

[0037] In some embodiments, a clamping hole is provided on each of the two branch structures 14 , and the rotating shaft is clamped and fixed in the clamping hole. In addition, some clamping structures can also be used to clamp and fix the rotating shaft in the clamping hole.

[0038] This embodiment can realize the hinged connection of the temples and the studs without screws, thus avoiding the defect that the screws fall off from the frame during long-term rotation.

[0039] Note that the above description of the end of the slide does not refer to the distance between the slide walls, but refers to the center of the shaft when the shaft moves to the end, that is, Figure 4 and Figure 5 The two points shown are at a distance a from each other, and both points are center points of the rotation axis.

[0040] The utility model also provides a glasses frame, comprising: two screwless glasses legs as described above.

[0041] This embodiment has all the advantages of the above-mentioned screwless glasses leg embodiment, which will not be described in detail here.

[0042] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
