Description

A kind of no screw hinge for spectacles

Technical field

The utility model discloses a kind of no screw hinge for spectacles, belongs to glasses hinge by International Patent Classification (IPC) (IPC) division Chain apparatus manufacturing technology field.

Background technique

Hinge on frame foot is mostly fixed together with bolt (screw) or welding by traditional eyewear, both hinge stability And durability is not grown, welded type hinge is to be fixedly connected, and cannot be dismantled；Although bolt type hinge can be dismantled, glasses spiral shell Bolt is tiny object, and when assembly and disassembly must be inconvenient by specific purpose tool.

Currently, in document no screw on the books hinge for spectacles, but component connection is complicated, such as Chinese document CN207216187U discloses a kind of no screw hinge for spectacles, including H-shaped card, connecting column and buckle connection sheet；H-shaped card First opening portion is fixedly connected with the frame of glasses, and buckle connection sheet is fixedly connected without crochet with the temple of glasses, the H-shaped Second opening portion of card is hinged by the connecting column and the full packet hook of buckle connection sheet；The opening two of second opening portion Side is equipped with barb, and the both ends of the connecting column are equipped with and two card slots corresponding with the barb；Connecting column is interspersed in institute It states in full packet hook and connecting column and full packet hook is rotatablely connected, the opening both sides of the second opening portion of the H-shaped card are caught in company It connects in corresponding two card slots of column；Both ends extend outwardly the part coupler body of full packet hook along longitudinal direction, are formed for limiting the H-shaped Half packet hook of card rotational angle.Another China document CN203894486U discloses a kind of no screw glasses hinge structure, packet Two stabilizer blades disposed in parallel are included, an Elastic buckle is equipped between two parallel legs, two parallel legs and Elastic buckle One end is arranged on the frame of glasses, and the other end of three extends to the mirror pin direction of glasses, Elastic buckle shape inwardly Camber button；The mirror pin close end is equipped with through-hole, forms central spindle between the through-hole and the end of mirror pin；When assembly, by bullet Property buckle penetrated from the through-hole of mirror pin, snap onto the central spindle of mirror pin in the arc button of Elastic buckle, so that mirror pin is connected to On frame, central spindle rotates between stabilizer blade and Elastic buckle in the document, that is, requires Elastic buckle elastic performance with higher, Otherwise, after a certain period of time, hinge is easy failure for central spindle rotation.

Utility model content

In view of the deficiencies of the prior art, the utility model provides that a kind of stability is good, a kind of no spiral shell with long service life Silk hinge for spectacles.

In order to achieve the above objectives, the utility model is achieved through the following technical solutions:

The abutting end of a kind of no screw hinge for spectacles, including first component and second component, two components is equipped with hinge hook and phase It is rotation slot on the inside of mutually occlusion, first component and second component hinge hook, is respectively equipped on the hinge hook of first component and second component Opening, with unification chain rivet in opening, chain rivet extended radially into rotation slot, and hinge hook and the second component hinge of first component are hooked in pair The interior rotation realization hinge of the rotation slot that should cooperate converts into or unfoldable shape.

Further, the hinge hook upper opening of first component and the hinge hook upper opening of second component are of different size, and chain rivet is equipped with Middle protrusion corresponding with two openings and the flat portion of ring, the flat portion of ring surround middle protrusion.

Further, chain rivet is in multi-diameter shaft, has larger diameter portion and smaller diameter portion, the hinge hook of first component on multi-diameter shaft The hinge hook that opening width is greater than second component is open, and the larger diameter portion of chain rivet is matched with the hinge hook opening of second component, chain The smaller diameter portion backstop of axis is matched with the first structure in the hinge hook inner wall of the opening two sides of second component, the smaller diameter portion of chain rivet The hinge hook opening of part.

Further, the rotation slot inner wall of first component is equipped with protrusion, and the hinge hook outer wall of second component is equipped with more than one When groove, first component and second component relatively rotate, protrusion is successively issued warning signal with groove detent in turn.

Further, the hinge hook of first component is divided into two parts by being open, and the two sides head that first component cuts with scissors hook clamps chain rivet Middle protrusion form shaft when first component and second component relatively rotate.

Further, the hinge hook of first component includes preceding segmental arc, goes back to straight section and head, and the hinge hook of second component includes preceding straight section And hook part, the wherein preceding straight section for returning straight section and second component of first component corresponding matching in unfolded state.

Further, the head of first component and the middle protrusion of chain rivet are corresponding, the head of first component and the centre of chain rivet The effect of the hook part of protrusion and second component, which is realized, to be relatively rotated.

The utility model is a kind of hinge for spectacles of the welding without screw, by the chain rivet with middle protrusion by first, Two components are connected and fixed, and the hinge hook of the first and second component is mutually twisted, and hinge folding is realized in rotation in the rotation slot of corresponding matching It closes or unfoldable shape is cooperated by means of the chain rivet with protrusion and rotated since the utility model hinge hitcher has one fixed width and thickness, Have many advantages, such as that stability is good, intensity is high, long service life.
