Fig. 1 to 2 are drawings of the present invention.

The present embodiment provides an elastic pressing structure, please refer to fig. 1, which includes a fixed block 10 and an elastic block 20. The fixing block 10 includes a hooking portion 11 for winding the rotation shaft 30. The elastic block 20 includes elastic ends 21, and the elastic ends 21 are located at two axial sides of the rotating shaft 30 installed on the hook portion 11, so that after the rotating shaft 30 is installed on the hook portion 11, the elastic ends 21 of the elastic block 20 are pressed at two ends of the rotating shaft 30. The rotation shaft 30 can rotate in the hooking part 11, and the elastic end 21 of the elastic block 20 presses both ends of the rotation shaft 30, so that the rotation shaft 30 can not only rotate, but also the rotation shaft 30 is bound in the hooking part 11.

Wherein, the hook part 11 is a circular arc surface for accommodating the rotating shaft 30, so that the rotating shaft 30 is wrapped by the hook part 11 and the rotating shaft 30 rotates stably.

If the elastic end 21 is a plane, the distance between the extrusion point of the elastic block 20 for extruding the rotating shaft 30 and the center line of the arc surface is smaller than the radius of the arc surface.

The part of the arc surface wrapping the rotating shaft 30 exceeds a half of the outer surface of the rotating shaft 30, so that the rotating shaft 30 is not easy to fall off.

The fixing block 10 further includes a fixing portion 12. The fixing portion 12 is used for fixing with a carrier. The hook 11 is provided at the upper end of the fixing part 12. The fixing portion 12 is fixed to a carrier, such as a glasses frame, and the hooking portion 11 protrudes from the carrier. The hook 11 extends upward from the fixing portion 12.

Further, the fixing block 10 further includes a transition portion 13. The transition part 13 is arranged between the hook part 11 and the fixing part 12; the transition portions 13 are disposed obliquely. The transition portion 13 is opposite to a connecting structure; and, with a certain inclination, this also makes the shaft 30 easy to mount with the arc surface.

In order to fix the fixing portion 12 to the carrier more firmly, the fixing portion 12 is provided with a step 121 disposed in an opposite direction.

The spring block 20 also includes a mounting portion 22. The mounting portion 22 is fixedly connected to the carrier or mounting block 10. The spring end 21 is provided at the upper end of the mounting portion 22.

In a further technical solution, the elastic block 20 further includes a bending portion 23. The bent portion 23 is provided between the elastic end 21 and the mounting portion 22. The bent portion 23 has a certain elasticity, so that the elastic end 21 has a sufficient elasticity to press the rotation shaft 30.

The spring end 21 is formed by an extension 24 extending through the bend 23. The extensions 24 are adapted to contact both ends of the rotation shaft 30, and after the rotation shaft 30 is fitted to the hooking portion 11, the extensions 24 having a resilient force are pressed against the outside of the rotation shaft 30. The elastic end 21 can be a plane, and the contact between the elastic end 21 and the rotating shaft 30 is a line contact; the elastic end 21 may be a cambered surface, and the contact between the elastic end 21 and the rotating shaft 30 is a surface contact.

The extension portion 24 is located on one side of the opening direction of the hook portion 11 so that the rotation shaft 30 can be mounted from the extension portion 24.

In the hook 11, when the rotating shaft 30 is not attached, the extension 2 is in a natural state, and in this state, the extension 24 and the rotating shaft 30 intersect with each other in a rotating space of the hook 11. After the rotating shaft 30 is installed on the hook 11, the extension 24 presses the outer surface of the rotating shaft 30 under the elastic action.

Referring to fig. 1 and 2, the hinge mechanism for glasses includes a frame 40, a leg 50, and the above-mentioned elastic pressing structure. The rotating shaft 30 is disposed at the end of the temple 50, and the fixing block 10 and the elastic block 20 are fixed to the glasses frame 40. After the shaft 30 of the temple 50 presses the elastic block 20, it is pushed inward, and then the shaft 30 is caught by the hook 11 of the fixing block 10, so that the glasses frame 40 and the temple 50 are rotated with each other. When the glasses need to be disassembled, the glasses legs 50 are extruded towards the glasses frame 40, and then the glasses legs 50 are pushed out towards the opening direction of the hook part 11, so that the glasses are convenient to disassemble and assemble.

Compared with the prior art, the elastic ends 21 of the elastic block 20 are arranged at the two sides of the hook part 11 of the fixed block 10, and the elastic force of the elastic ends 21 on the rotating shaft 30 is uniform, so that the rotating shaft 30 rotates stably. Because the elastic end 21 extrudes the rotating shaft 30 in the hook part 11, the elastic end 21 of the pressing elastic block 20 can be disassembled and assembled, the disassembly and the assembly are convenient, and the structure is simple.

The technical contents of the present invention are further illustrated by examples only for the convenience of the reader, but the embodiments of the present invention are not limited thereto, and any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the utility model is subject to the claims.
