Embodiment

Figure 1A, 1B and 1C show first kind of embodiment of the present utility model.

Shown in Figure 1A and 1B, hinge for spectacles is formed by connecting by the catapult core assembly by preceding hinge 10 and catapult box 20.Shown in Figure 1B, the catapult core assembly comprises catapult core 30, sleeve pipe 34, spring 35, catapult core 30 has catapult core print 31, the catapult core bar 33 that is used for pocketed springs 35 that is rotationally connected with preceding hinge, the catapult core neck 32 that is connected catapult core print 31 and catapult core bar 33, syndeton for catapult core bar 33 and catapult core neck 32, preferably be embodied as the perpendicular steps type, but also can otherwise implement, for example can be comparatively mild syndeton.

In the present embodiment, have only a catapult core 30 and sleeve pipe 34, its middle sleeve 34 is installed in the catapult box 20 and with catapult box 20 fixedlys connected, and the catapult core is rotatably connected at its head and preceding hinge (bidentate hinge), and cover tubing 34, thereby further be plugged in the catapult box 20.In order to overlap tubing 34, shown in Fig. 1 C with the shaped design of the endoporus 22 of sleeve pipe 34 for to match with the catapult core, shown in Figure 1B and 1C, the improvement of being done in the present embodiment mainly is: holding section 23 is set on sleeve pipe 34, its profile with catapult core neck 32 matches, thereby can firmly overlap tubing further.During concrete the installation, sleeve pipe 34 is sleeved on the catapult core neck 32, simultaneously offer holding section 23 symmetrically in the top and the bottom of sleeve pipe 34, thereby after with sleeve pipe 34 suits, just in time the both sides with catapult core neck 32 fit, and that the length of sleeve pipe 34 can be designed to is consistent with catapult core neck 32, separately spring 35 is sleeved on the catapult core bar 33 in addition, when specific design, this holding section 23 is designed to mounting groove, the profile of catapult core neck 32 and the shape of mounting groove 22 are suitable, so the catapult core can firmly be installed in the catapult box.

Shown in Figure 1A and 1B, catapult core neck 32 be shaped as square structure, and match with the shape of mounting groove 22.

Fig. 2 shows second kind of embodiment of the present utility model.

Compare with first embodiment, the hinge for spectacles in the present embodiment comprises two catapult core assemblies, as shown in Figure 2, preceding hinge 10 is three teeth hinges, is connected with two catapult cores 30, as shown in Figure 2, be provided with two independently endoporus 22 in the sleeve pipe 34, catapult core assembly of each endoporus 22 suit.Simultaneously with each endoporus 22 corresponding position holding section 23 is set on sleeve pipe 34, this holding section 23 is laterally zygomorphic grooves, and its shape matches with the shape of catapult core neck 32.
