Description

Eyeglasses frame elastic hinge

Technical field

The present invention relates to a kind of eyeglasses frame elastic hinge.

Background technology

Existing eyeglasses frame elastic hinge, as shown in Figure 7, comprise that the hinge bidentate does not draw, catapult core 100 and catapult box body 200, described catapult core 100 comprises monodentate core body 110, keeper 120 and spring 130, described keeper 120 and described spring 130 are enclosed within on the monodentate handle 111 of described monodentate core body 110, described spring 130 is positioned at after the keeper 120, is provided with one at the tail end of described monodentate handle 111 and prevents the flat position 112 that spring comes off; The head end 113 and the described hinge bidentate of described monodentate core body 100 flexibly connect by screw, and the keeper 120 of described catapult core 100 and spring 130 are arranged in the described catapult box body 200; The keeper 120 of described catapult core 100 is that axial cross section is I-shaped circular turned body, after this I-shaped keeper is loaded into catapult box body 200, circular groove 121 corresponding to the circular turned body extrudes a concave point 210 again on catapult box body 200 again, the circular turned body is positioned in the catapult box body 200, its accuracy requirement of elastic hinge of making structure like this is very high, careless slightly, groove 210 on the catapult box body 200 just with circular groove 121 corresponding not the going up of circular turned body, whole elastic hinge must be scrapped; Existing also have a kind of eyeglasses frame elastic hinge, as Fig. 8 and shown in Figure 9, it is compared with elastic hinge shown in Figure 7, its general structure is identical, different is that keeper 120 is to be split into several pieces elastic steel sheets 122 with cutting on the thin skin steel pipe, pull back these elastic steel sheets 122 horn-like, in addition, in described catapult box body, establish groove 220, when the keeper 120 of this structure is pushed onto in the catapult box body 200, when arriving its groove 220, then elastic steel sheet 122 opens, elastic steel sheet 122 withstands in the groove 220, and whole keeper 120 is positioned in the groove 220, does not break away to guarantee catapult core 100 and catapult box body 200.After the elastic hinge of above-mentioned two kinds of different structures was connected on the spectacle frame, there was a common problem in they, that be exactly elastic hinge be inseparable one-piece construction, after elastic hinge damaged, then the mirror leg of whole spectacle frame all must be scrapped.

Summary of the invention

The objective of the invention is to overcome the problems referred to above, provide a kind of eyeglasses frame elastic hinge that can change the catapult core to society.

Another object of the present invention is that the replacing of catapult core is very convenient quick.

Technical scheme of the present invention is: design a kind of eyeglasses frame elastic hinge, comprise hinge bidentate, catapult core and catapult box body, described catapult core comprises monodentate core body, keeper and spring, described keeper and described spring housing are on the monodentate handle of described monodentate core body, described spring is positioned at after the keeper, is provided with one at the tail end of described monodentate handle and prevents the flat position that spring comes off; The head end of described monodentate core body and described hinge bidentate flexibly connect, and the keeper of described catapult core and spring are arranged in the described catapult box body, and described catapult core is removable by its keeper with described catapult box body and is connected.

Described removable being connected on the outer wall of described keeper is provided with external thread, is provided with internal thread hole in described catapult box body, and described keeper is connected by the interior internal thread hole screw of external thread on its outer wall and described catapult box body.

On the monodentate core body of the contact site of described monodentate core body and keeper, be provided with the pin thread position, on the keeper of the contact site of described monodentate core body and keeper, be provided with the box position, the interlock that matches of described pin thread position and described box position.

Described pin thread position is flat protuberance, and described box position is a draw-in groove, and described flat protuberance is stuck in the described draw-in groove.

Described pin thread position is that xsect is rule or random geometry, and described box position is the corresponding hole of geometric configuration.

Described regular geometric shapes is triangle, rectangle, rhombus or hexagon.

The present invention has adopted the catapult core to be removable syndeton by its keeper and described catapult box body, just can realize the replaceable of catapult core, when elastic hinge damages, only needs to change the catapult core and just can re-use, and can economize on resources like this; In addition, invention has also been adopted on the monodentate core body of the contact site of described monodentate core body and keeper and has been provided with the pin thread position, on the keeper of the contact site of described monodentate core body and keeper, be provided with the box position, described pin thread position is stuck in the structure in the described box position, like this, and when need are changed the catapult core, only need rotation monodentate core body just can drive the keeper rotation, so, just can easily load and unload the catapult core quickly, and not need professional and professional tool all can realize.
