Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Of the present utility modelly without the screw elastic spectacle frame, comprise a spectacle-frame processed by sheet metal 1, in the both sides of spectacle-frame 1, be provided with to the connecting portion 2 of spectacle-frame 1 trailing flank bending, connecting portion 2 is provided with leg of spectacles 3, between connecting portion 2 and leg of spectacles 3, by flexible connection mechanism, interconnects.

As shown in Figure 1, after spectacle-frame 1 is launched, connecting portion 2 is integrated and is connected with spectacle-frame 1, connecting portion 2 is rectangular strip, have a connecting portion hole 7 arranged along connecting portion 2 length directions on connecting portion 2, be provided with in the inboard in connecting portion hole 7 and there is flexible shell fragment 4, this shell fragment 4 is the parts that form flexible connection mechanism, this shell fragment 4 can adopt the mode of welding that the front end hole wall place in the fore-end of the front end of shell fragment 4 and connecting portion 2 or connecting portion hole 7 is connected and fixed, for easy to process, shell fragment 4 is connected with connecting portion hole 7 one, the front end of shell fragment 4 is connected with the front end hole wall in connecting portion hole 7, and shell fragment 4 is upper, lower two ends and rear end and connecting portion hole 7 upper, lower two ends hole wall is not connected with the rear end hole wall, shell fragment 4 is slightly to the inside bend of connecting portion 2, front end at shell fragment 4 is provided with the hook portion 6 of protruding towards the inner surface of shell fragment 4,

On the both sides in connecting portion hole 7, connecting portion 2, be provided with towards the convex tendon 10 of the outside projection of connecting portion 2.Convex tendon 10 is rectangular strip, and its length direction is parallel with the length direction of connecting portion 2.

As shown in Fig. 2-1 and 2-2, the connecting portion 2 of spectacle-frame 1 both sides is that bending angle approaches an angle of 90 degrees to the bending of the rear side surface of spectacle-frame 1.

As shown in Fig. 3-1 and Fig. 3-2, be provided with the shell fragment hole 5 of confession hook portion 6 grabs at the front end of leg of spectacles 3, shell fragment hole 5 is another parts that form flexible connection mechanism, the length in this shell fragment hole 5 equates with the thickness of shell fragment 4; The width in shell fragment hole 5 equates with the width of shell fragment 4, forms a rotating shaft 9 between the front end hole wall in shell fragment hole 5 and the front end of leg of spectacles 3.

As shown in Fig. 4-1 and Fig. 4-2, leg of spectacles 3 only is with leg of spectacles 3 differences in Fig. 3-1 and Fig. 3-2: the platform 8 that is provided with a sinking on this part leg of spectacles 3 near shell fragment hole 5, shell fragment hole 5 and rotating shaft 9 all are arranged on platform 8, when opening leg of spectacles 3, connecting portion 2 just in time falls into platform 8.

As Fig. 5-1 to as shown in 5-3, the front end of leg of spectacles 3 is inserted from the gap between shell fragment 4 and connecting portion 2, shell fragment 4 front end distortion, thereby the front end of leg of spectacles 3 can be inserted, and when entering to 5 place, shell fragment hole, hook portion 6 snaps in shell fragment hole 5 and catches on rotating shaft 9, leg of spectacles 3 can be rotated for axle center along rotating shaft 9, due to the elastic force of shell fragment 4, hook portion 6 tightly catches on leg of spectacles 3, thereby realizes and the hinged identical function of screw.

As shown in Figure 6, after leg of spectacles 3 is amounted to, the front end end of leg of spectacles 3 withstands on the inner side end of connecting portion 2, and now shell fragment 4, to the direction perk of connecting portion 2 inner surfaces, under the elastic force effect of shell fragment 4, can make leg of spectacles close up fast.

After leg of spectacles 3 is opened, the both sides in connecting portion hole 7 are subject to coming from the pressure of leg of spectacles 3, and now, convex tendon 10 plays the dynamics of strengthening 7 upper and lower both sides, connecting portion hole, thereby makes connecting portion 2 indeformable, to reach quality requirements.

As shown in Figure 7, after leg of spectacles 3 is opened, and the contact parallel with the inner surface of connecting portion 2 of the outer surface of leg of spectacles 3, now shell fragment 4 falls after rise, under the elastic force effect of shell fragment 4, leg of spectacles 3 clamping tightly by shell fragment 4.

The utility model is removed between spectacle-frame and leg of spectacles and is connected used screw, the substitute is and adopts elastic connection structure to be connected, and removes maintenance from and again reinforces the serviceable life of having improved spectacle frame.
