Description

Technical Field

[0002] In daily life, some people cannot see things clearly due to vision problems, so they need to wear glasses, and some people wear glasses as decorations. For example, the Chinese invention patent with patent number: CN202111094340.1 discloses a pair of glasses with a detachable glasses frame, including a first frame, the number of the first frames is two groups, and the two groups of first frames are both installed with a card block on the opposite side, the bottom of the two groups of first frames is provided with a second frame, and the two groups of second frames are also installed with a card block on the opposite side, and a locking block is slidably installed on the surface of the card block, and a shell is installed on the surface of the locking block away from the card block, and a mounting plate is provided inside the shell, and a number of baffles are installed on one side of the mounting plate. The present invention divides the frame into two parts, both of which are fixed by the card block and the locking block. When the lens falls accidentally, it only needs to remove the locking block to separate the first frame and the second frame, and then reinstall the lens and fix it by the locking block. The operation is simple, and the glasses can be guaranteed not to be damaged during the installation process, thereby ensuring the performance and service life of the glasses.

[0003] In the above disclosed frame structure, when the two frames are folded, a set of hinge structures are directly set to fold and shrink. However, since the existing hinge movable devices are fixed and cannot be adjusted in distance, if the distance between the two ends of the hinge is too small, when the frames are folded, the two frames are close to each other, which may squeeze the nose pads set on the sides of the frames. If the force is severe, the nose pads may be directly squeezed and deformed. Summary of the invention
