Detailed Description

The folding structure of the spectacle frame according to the utility model will be described in further detail with reference to fig. 1 to 4.

As can be seen from fig. 1 to 3, a folding structure of a spectacle frame comprises a hinge 1 and pile heads 2 fixed at two sides of the spectacle frame, wherein the hinge 1 comprises a hinge main body 11 hinged with a hinge leg, a spring 12 and a screw 13 are arranged in a counter bore 111 of the hinge main body 11, a guide post 21 is arranged at one side surface of the pile heads 2 matched with the hinge 1, a guide hole 112 matched with the guide post 21 is formed in the hinge main body 11, the guide post 21 and the guide hole 112 can guide the pile heads 2 and the hinge 1 to rotate relatively, the counter bore 111 and the guide hole 112 are communicated through a communication hole, one end part of the screw 13 passes through the spring 12, and the end part passes through the communication hole and is connected with the guide post 21 arranged in the guide hole 112, so that the hinge 1 and the pile heads 2 are rotationally connected, and the elasticity of the spring 12 enables the hinge 1 and the pile heads 2 to be mutually attached.

As can be seen from fig. 3 and fig. 4, one side surface of the pile head 2, which is matched with the hinge 1, is provided with one or more than one limiting raised line 22, the hinge main body 11 is provided with a limiting recessed groove 113, which is matched with the limiting raised line 22, when the hinge 1 is in a folded position or is worn, the limiting raised line 22 is placed in the limiting recessed groove 113, so as to limit the relative rotation of the hinge 1 and the pile head 2, when the hinge 1 of one mirror leg rotates relative to the pile head 2 of the mirror frame, the limiting raised line 22 is separated from the limiting recessed groove 113 on the corresponding side by overcoming the elastic force of the spring 12 and is re-transferred into the limiting recessed groove 113 on the other side, so that when the mirror leg is in the folded position or is worn, the limiting raised line 22 is still placed in the limiting recessed groove 113, and the relative rotation of the hinge 1 and the pile head 2 in the folded position or the worn position can be effectively avoided, thereby improving the wearing stability.
