[0019] The following will be described in detail in combination with the accompanying Figures 1-5 The present application will be further described in detail.

[0020] The embodiment of the present application discloses a connection structure for adjusting the opening degree of glasses.

[0021] Reference will be made to Figures 1-5The connecting structure for adjusting the opening degree of glasses comprises a hinge 1, a metal sheet 2 and an elastic piece 3. One end of the hinge 1 penetrates into a frame 7 and is fixedly connected with the frame 7. The other end of the hinge 1 is rotationally connected with a temple 4. The temple 4 is provided with a slot 41 for the hinge 1 to penetrate into, on the side close to the frame 7. The metal sheet 2 is U-shaped and wrapped outside the elastic piece 3. The two sections of the metal sheet 2 are respectively abutted with the frame 7 and the temple 4. The hinge 1 penetrates through the two sections of the metal sheet 2 and the elastic piece 3. The two sections of the metal sheet 2 are both provided with a gap 21 for the hinge 1 to penetrate through. The middle part of the elastic piece 3 is provided with a gap 31 for the hinge 1 to penetrate through.

[0022] The elastic piece 3 is made of silica gel.

[0023] The elastic piece 3 is gradually expanded from the middle of the two temples 4 to the outside of the two temples 4. The opening of the metal sheet 2 is towards the outside of the two temples 4.

[0024] The end of the hinge 1 connected with the temple 4 is provided with a connecting hole 11. The temple 4 is provided with a sleeve 5 and a screw 6. The inner diameter of the sleeve 5 is matched with the hole diameter of the connecting hole 11. The top surface of the temple 4 is provided with a receiving hole 42 for the sleeve 5 to be embedded in. The bottom surface of the sleeve 5 is in contact with the top surface of the hinge 1. The screw 6 penetrates through the connecting hole 11 from the side of the hinge 1 away from the sleeve 5 and penetrates into the sleeve 5. The bottom surface of the temple 4 is provided with a receiving hole 43 for the screw 6 to be embedded in. The receiving hole 42, the receiving hole 43 and the slot 41 are communicated. The receiving hole 42, the receiving hole 43 and the connecting hole 11 are coaxially arranged. The inner peripheral wall of the sleeve 5 is provided with internal threads matched with the external threads of the screw 6. The screw 6 is threadedly connected with the sleeve 5, so as to realize the rotational connection between the hinge 1 and the temple 4.

[0025] The end of the elastic piece 3 on the outside of the two temples 4 is provided with a limiting ring edge 32. The side of the limiting ring edge 32 close to the elastic piece 3 is simultaneously abutted with the frame 7, the temple 4 and the two ends of the metal sheet 2. The limiting ring edge 32 is integrally formed with the elastic piece 3. When the metal sheet 2 and the elastic piece 3 are assembled, the two ends of the metal sheet 2 are abutted on the limiting ring edge 32. Then the metal sheet 2 and the elastic piece 3 are clamped between the frame 7 and the temple 4, so that the limiting ring edge 32 is abutted with the frame 7 and the temple 4. This is convenient for positioning during assembly and improves the assembly efficiency.

[0026] Since the U-shaped metal sheet 2 and the silica gel elastic member 3 both have self-adapting contraction, when the face size of the wearer is small, the metal sheet 2 and the elastic member 3 keep the outward expansion force at the end close to the outer side of the temple 4, so that the opening degree between the temple 4 and the frame 7 is automatically kept to fit the face of the wearer, when the face size of the wearer is large, the metal sheet 2 and the elastic member 3 are squeezed and contracted at the end close to the outer side of the temple 4, so that the opening degree between the temple 4 and the frame 7 is automatically enlarged, therefore, when the glasses of the technical scheme of the present application are worn, the opening degree between the temple 4 and the frame 7 can be automatically adjusted to adapt to the wearers with different face sizes, and the fitting degree and the comfort of the wearer are improved.

[0027] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: all equivalent changes made on the structure, shape, principle of the present application should be covered in the protection scope of the present application.
