CN87200064U - Nonsewing buttons - Google Patents

Abstract

The utility model discloses a nonsewing button uneasy to fall off and convenient and quick to assemble. The button can be made of injection moulding material, improving the fastness of the button and preventing from falling off. The utility model has the advantages of high production efficiency, low cost, high efficiency, and simple working process.

Description

Nonsewing buttons

The utility model relates to and is used for clothes, tent and other flexible thin material's manufactured goods, able to turn on or off part.ICL can be summarized in A44B.

Existing button, mostly with linear slit on able to turn on or off clothes or articles for use that fabric, flexible thin material make.Also useful elasticity snap-fastener form rivet clasp is on fabric or flexible thin material's goods.Preceding a kind of, line is easy to wear, and button easily comes off.The back is a kind of, only is suitable for not too thick goods, and parts are many, manufacturing process and assembly technology complexity, will use metal material, and locking function is not strong.These two kinds in the production of articles operation, influence efficient and improve.As for the button that minority connects with metal bracelet, its complex process is difficult for a large amount of production.

Task of the present utility model is to provide a kind of, has strong locking function; Can be used for thicker goods; When the strength of materials is enough, can not come off; Be easy to produce; Be easy to the novel button of binding.

Task of the present utility model is finished as follows, is described in detail as follows in conjunction with the accompanying drawings:

The assembling schematic appearance of figure one, this series button

The assembling generalized section of figure two, this series button

Figure three, this series button main body engagement head schematic top plan view

The locknut generalized section of figure four, this series button

Figure five, this series button adopt the assembling generalized section of screw thread, nut embodiment

With reference to figure one, figure two. Whole button is made up of main body＜2 〉, facing layer＜1〉and locknut＜5 〉.

The outer surface of button main body＜2〉can be determined by injection moulding mould decorative pattern, also can form with facing layer＜1〉the adhesion main body＜2〉of glue with various patterns, material, moulding, or fixedly form with additive method.

Button main body＜2〉middle-end is following to be compressing tablet＜3 〉, has the engagement head＜4〉of compressible elastomeric.Engagement head＜4〉has hole, a garden＜7〉on the axis, and is divided into pintongs by cross deep trouth＜6 〉.The end of engagement head＜4〉has the vertex of a cone＜8〉and back stop slot.The width of back stop slot, the degree of depth will be complementary with aperture, the degree of depth in the retaining hole＜9〉of locknut＜5 〉.

On material products such as fabric or flexible thin layer＜10 〉, after the punching of nail catcher position, lock seaming or the reinforcement, the engagement head＜4〉of button is inserted in the hole, add locknut＜5〉from the goods another side again, firmly pressing, engagement head＜4〉diameter of the band vertex of a cone＜8〉and back stop slot is got into regard to being compressed in the retaining hole＜9〉of locknut＜8 〉, makes main body＜2〉and locknut＜5〉and goods＜10〉be combined into inseparable integral body.

Locknut＜5〉also can injection mo(u)lding.Above locknut＜5〉aperture＜9〉certain taper is arranged, its aperture and the degree of depth should be complementary with the back stop slot size of the engagement head＜4〉of main body＜2 〉.

This button not only can adopt the assembling mode of the locknut＜5〉in above-mentioned resilient engagement head＜4〉and band retaining hole＜9 〉, also can be according to the scheme shown in the figure five, with bolt＜12〉and nut＜11〉assembling mode.But, after nut＜11〉compresses goods,,, make the bolts and nuts local fusing, or make partly thread damage along the indication of arrow P shown in figure position with other instruments such as plastic welding gun, flatirons, nut＜11〉can not be withdrawed from, button can not come off.

Claims (2)

1, a kind of button without linear slit is characterized in that:

A, its assembling mode have adopted the resilient engagement head and locknut or bolts and nuts etc. are simple and easy, assemble mode reliably.

B, its finish coat can with the main body single injection-molded, also can be bonded with the finish coat of various patterns, various material, various moulding.

C, the special clamp clamps resilient engagement head of use can disassemble button and the locknut that has assembled.

2, button according to claim 1 is characterized in that with the position that is rubbed mutually by the locking goods be high-abrasive materials such as macromolecular compound, the intensity height, and coefficient of friction is little.
