Description

Screw-free and welding-free hinge structure for mirror foot steel sheet Technical Field The utility model relates to the field of screwless eyeglass assembly, in particular to a screwless and solderless hinge structure of a steel sheet of an eyeglass leg. Background The two sides of the glasses frame of the common glasses are respectively assembled with the glasses legs, the pivot joint part at the front end of the glasses legs corresponds to the pivot joint part of the glasses frame, and then the two glasses legs can be unfolded or folded corresponding to the glasses frame by screw threads. Because the glasses are assembled by the screws, the glasses must be locked by tools such as screwdrivers, and the assembly time is shortened, and the production and manufacturing costs are increased. The screw is easy to loosen or fall off under the action of repeatedly unfolding and folding the temples by a user, however, the screw is loosened and is needed to be screwed by a special tool, and if the screw is lost, the user needs to personally maintain and arrange the proper screw in the glasses, and the defects often bother the wearer of the glasses. Therefore, there are many eyeglass structures developed between the workshops without using screws, such as the patent application No. TW097212952, entitled eyeglass hinge device, however, the above patents can improve the problem caused by screw locking, but are inconvenient in assembly and the eyeglass legs are not effectively limited in unfolding and folding, so that the eyeglasses are slightly insufficient. Further, as disclosed in the patent application No. TW112204954 entitled screwless and solderless eyeglass structure, the eyeglass structure with operation elasticity is disclosed, which comprises a frame and a pair of eyeglass legs arranged on two sides of the frame, wherein the pair of eyeglass legs and the frame are connected through a mortise and tenon connection structure, and the mortise and tenon connection structure is assembled by a spleen structure, a hook structure, a spring structure and a banker structure. The above-mentioned technique can be opened and closed by means of proper elastic force when it is opened and closed, but its whole structure is complex, components and components are many, and its assembly is not easy, and the defects of the prior art are that it utilizes special-shaped extrusion strip-shaped processing, and then makes welding processing after cutting hinge tooth-shaped processing, so that it is time-consuming and labor-consuming and its cost is high. Disclosure of utility model The utility model aims to provide a screw-free and welding-free mirror foot steel sheet hinge structure, in particular to a screw-free and welding-free mirror foot steel sheet hinge structure which has the advantages of simple structure, convenience in assembly and high stability, and aims to solve the problems of complex integral structure, multiple components and difficult assembly, and the defects in the prior art that special extrusion strip processing is adopted, and welding processing is performed after cutting hinge tooth processing, so that time and labor are wasted. In order to achieve the above purpose, the present utility model adopts the following technical scheme: A screw-free and welding-free hinge structure for a steel sheet of a mirror foot is provided, wherein at least one hinge structure for the steel sheet is arranged between a joint part at the outer side of a mirror frame and the front end part of the mirror foot, the hinge structure for the steel sheet comprises, The hinge unit, a side of hinge unit is equipped with first hook portion, second hook portion, third hook portion from front to back respectively, preceding tip corresponds third hook portion department and is equipped with rather than the fixed locating hole of relative trip, preceding tip is located the locating hole the place ahead and is equipped with one and inlays the perforation, inlay the perforation and permit first hook portion and second hook portion to wear to establish, the group joint portion end reason is equipped with the notch that can supply the second to collude the portion to put into, the notch provides the hinge unit and drives the activity space of mirror foot expansion, receipts displacement, the group joint portion is located notch and sets gradually the trip hole and inlay the trip hole towards the picture frame direction, the trip hole provides when the hinge unit drives the mirror foot, it is supplied to inlay the trip hole provides when hinge unit drives the mirror foot expansion, supplies first hook portion embedding location. Furthermore, a wall thickness is arranged between the notch and the clamping hole, a hook space is formed at the inner side of the second hook part, and the second hook part and the hook space are positioned corresponding to the wall thickness. Furthermore, the mirror frame and the mirror legs are manufactured by adopting a
