Detailed ways

1 to 3 show a first embodiment of the present utility model.

As shown in FIG. 1 , the eyeglass hinge is formed by connecting a front hinge 10 and a slingshot box 20 through a slingshot core assembly. As shown in Figure 2, the slingshot core assembly includes a slingshot core 30, a sleeve 34, and a spring 35. The slingshot core 30 has a slingshot core head 31 that is rotatably connected to the front hinge, a slingshot core rod 33 for the sleeve spring 35, and a slingshot core that is connected to the spring 35. The slingshot core neck 32 of the head 31 and the slingshot core rod 33, the sleeve pipe 34 is sleeved on the slingshot core neck 32, and one end of the spring 35 is in contact with the sleeve pipe 34, and the other end is fixed at the end of the slingshot core rod 33. In this embodiment, there is only one slingshot core and sleeve, and only one installation hole 22 is provided on the slingshot case 20. The sleeve 34 is installed in the installation hole 22 of the slingshot case 20 and is fixedly connected with the slingshot case. Its head is rotatably connected with the front hinge (double tooth hinge) and can slide in the sleeve pipe 34. The improvements made in this embodiment are mainly: the slingshot case 20 is provided with a guide groove starting from the front end face and parallel to the axial direction of the slingshot core (the front end face is the end face of the slingshot case facing the front hinge), the guide groove 21 is compatible with the installation The holes 22 communicate with each other, and the width of the slingshot core head 31 close to the slingshot core neck 32 is greater than the width of the slingshot core neck. To the guiding effect; the shape of the casing is square, which matches the shape of the installation hole of the slingshot box, as shown in Figure 3. The shape of the slingshot core neck 32 is also a square structure, and matches the shape of the inner hole of the casing; the two opposite outer surfaces of the slingshot case are provided with screw holes 23 passing through the mounting holes, and screws 24 are embedded in the screw holes, and the screws 24 connect the The sleeve is fixed in the installation hole. Through the dual functions of the guide part and the mounting hole cooperating with the sleeve, the slingshot core can be better prevented from shaking.
