Abstract

The utility model relates to a hook which is applied in a necklace, a bracelet, a foot chain, or a mobile telephone chain, a portfolio chain, and etc. The utility model aims to mainly solve technique problems of the existing technology that manufacturing is complex; a hook is easy to part and a spring is easy to break away, etc. The utility model is composed of two hook films and a hinge; wherein the two hook films can mutually buckle each; the hinge is clamped between the two hook films and control the hook to open or close; the hinge is provided with a spring; a hook part along the hook film forms a projecting side which projects from the hook film surface. The utility model is characterized in that: a hook loop is positioned between the two hook films and is integrated into one entity with the two hook films. As the hook loop and the two hook films are integrated into one entity, the connection is solid; once fold the two hook films in a center of the hook loop, and then seal the two hook films, the manufacturing is completed; as the sealing parts are reduced, the manufacture is simple, working efficiency is greatly improved; moreover, losing the chain caused by departure of the hook loop is avoided.

Description

Decorative chains is with linking up with

Technical field

The utility model relates to the hook of a kind of necklace, bangle, pin chain or usefulness such as mobile phone chain, suitcase chain, specifically to a kind of improvement of existing decorative chains with hook.

Background technology

Existing decorative chains generally is between the hook lamellar body of two splits the folding sheet to be set with hook, then two hook lamellar bodies is welded together, hook ring on its welded top again, therefore make the welding position increase, make complexity, the production time is longer, greatly reduces production efficiency.In addition, when external impact took place, the welding position of hook ring ruptured easily, causes decorative chains to come off easily, and expensive jewellery are lost, and causes very big economic loss.Also having a shortcoming is to wear repeatedly and separating in the process of tearing ornaments open, owing to shrink and the spring that expands is placed in the spring groove of folding sheet, and the groove inwall of spring groove is a vertical plane, so spring is easy to spin off in groove, can't use.

Summary of the invention

The utility model is in order to solve making complexity that prior art exists, fracture and spring technical problem such as disengaging easily easily.

In order to solve the problems of the technologies described above, the utility model comprises two hook lamellar bodies that can be interlocked and is clipped in the folding sheet of two control hook foldings in the middle of the hook lamellar body, on the folding sheet spring is housed, hook portion along the hook lamellar body is formed with the nib that protrudes in the hook plate surface, it is characterized in that: be provided with between two hook lamellar bodies and two hook plate bodily form all-in-one-pieces, one hook ring.

Also have following feature in the utility model: described folding sheet comprises control lever and folding end, control lever and folding end form " people " font, the upper and lower both sides of folding sheet are provided with the cylindrical projections axle, the cylindrical projections axle is inserted in the circular groove of linking up with on the lamellar body, the folding sheet can rotate in two hook lamellar bodies, is provided with the spring groove of placing spring on the upper surface of folding sheet.

In order to prevent that spring from spinning off in spring groove, in the utility model, also has following feature: the tapered inclined-plane of groove inwall of described spring groove.

The utlity model has following advantage and good effect: since of the present utility model two the hook lamellar bodies and with its in the middle of hook ring be integral type, connect more firm, during making if with hook ring be after the doubling of center again welding can finish, the welding position reduces, make simple, improved production efficiency greatly, and can avoid linking up with ring portion fracture chain is lost.

Among the figure 10, the hook lamellar body; 11, hook portion; 11a, nib; 12, groove; 20, folding sheet; 21, control lever; 22 folding ends; 23, outstanding axle; 24, spring groove; 30, hook ring; 40, spring; 100, hook; 200, decorative chains.

The specific embodiment

Referring to Fig. 1～Fig. 4, the utility model hook 100 comprises two hook-type hook lamellar bodies 10 that can be interlocked and is arranged on the folding sheet 20 that 100 foldings are linked up with in two controls in the middle of the hook lamellar body 10, spring 40 is housed on the folding sheet 20, hook portion 11 along hook lamellar body 10 is formed with the nib 11a that protrudes in hook lamellar body 10 surfaces, its role is to guarantee that two hook lamellar bodies 10 fasten the inner certain space that forms in back and place folding sheet 20, and become the welding position after two hook lamellar bodies 10 fasten.Between two hook lamellar bodies 10, be provided with a hook ring 30 that forms one with two hook lamellar bodies 10.Described folding sheet 20 comprises control lever 21 and folding end 22, control lever 21 and folding end 22 form " people " font, the upper and lower both sides of folding sheet 20 are provided with cylindrical projections axle 23, cylindrical projections axle 23 is inserted in the circular groove of linking up with on the lamellar body 10, folding sheet 20 can rotate in two hook lamellar bodies 10, make and hook 100 foldings on the upper surface of folding sheet 20, be provided with the spring groove 24 of placing spring 40.In order to prevent that spring 40 from spinning off in spring groove 24, the tapered inclined-plane of groove inwall of spring groove 24.Referring to Fig. 3, earlier with an end of decorative chains 200 with after hook ring 30 links to each other, when pulling moving control lever 21, when folding sheet 20 interior springs 40 shrank, folding end 22 can tilt inwards, i.e. formation can be plugged the space of stating decorative chains 200.After this, when finger left control lever 21, the spring 40 in the folding sheet 20 was according to the elastic recovery principle, and folding end 22 rotates along counter-clockwise direction, makes hook portion 11 contact with folding end 22, thereby reaches the purpose of control decorative chains 200.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
