Abstract

The utility model discloses an elastic buckle which comprises a V-shaped elastic body and a convex grain, wherein the V-shaped elastic body and the convex grain are arranged in a split mode; the V-shaped elastic body is formed by bending a steel wire, and one end is bent with an inserting part; an inserting hole is arranged on the convex grain; the inserting part of the V-shaped elastic body is inserted in the inserting hole. Because the bending and the forming of the steel wire is much easier than that of metal sheet materials, the cost can be reduced. Moreover, the elasticity of the utility model is large, which is difficult to break. Moreover, the strength of the convex grain is large and no inlay iron head needs to be inserted in the convex grain. The rate of finished products is high. The assembly between the convex grain and the V-shaped elastic body is easy.

Description

A kind of elasticity button

Technical field

The utility model relates to a kind of elastic element, particularly the elasticity that two flexible rod member fixed card are closed can be buckled about a kind of.

Background technique

In the prior art, a kind of elasticity button is arranged as shown in Figure 1, it is arranged in the internal and external casing as tent bar or footpost etc., as the Telescopic Fixed device of internal and external casing.This elasticity button comprises a V-shape piece and a protruding grain, and this elasticity button is generally formed by rectangular metal sheet integrated punching bending, and for increasing the intensity of protruding grain, also embeds one in protruding intragranular portion usually and inlays the iron head.Yet but there is following defective in the elasticity button of this kind structure:

1, because this elasticity button is that a metal sheet is one-body molded, when being applied to fix occasion with stronger dynamics, must increase the thickness of this metal sheet, can reach requirement of strength, but thicker sheet forming difficulty, yield rate is low, so the manufacture cost height; And intensity is too high, during use easily at the rupture of V-shape piece, thereby it is scrapped.

2, because its protruding grain is impact briquetting, protruding grain sidewall when the iron head is inlayed in embedding, very easily splits the Lock-in short slot, and increases reject rate from this short slot root, improve manufacture cost.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of elasticity button, fixes occasion with stronger dynamics and moulding easily even this elasticity button is applied in, and yield rate height, easy-rupturing not.

For solving the problems of the technologies described above, technical solution of the present utility model is: a kind of elasticity button, comprise V-arrangement elastomer and protruding grain, and described V-arrangement elastomer and protruding grain split setting, and the V-arrangement elastomer bends by a steel wire and forms, and the one end is bent with a cutting graftage part; Described protruding grain is provided with spliced eye, and the elastomeric cutting graftage part of V-arrangement inserts in it.

The elastomeric cutting graftage part of described V-arrangement is bent with the V-arrangement projection.

The elastomeric the other end of described V-arrangement is bent with the U-shaped clamping part vertical with this V-arrangement place.

The elastomeric the other end of described V-arrangement is fixed a perpendicular clamping part.

After adopting such scheme, the utlity model has following advantage:

1, elastomer portion of the present utility model is no longer formed by the metal sheet bending, but form by the round wire bending, therefore fixing occasion with stronger dynamics, only need to increase gauge of wire, and the bending forming of steel wire is easy more than metal sheet, and elasticity easy-rupturing very much not.

2, protruding grain of the present utility model is also no longer by the metal sheet impact briquetting, but made by slug or hard plastic cement piece, so its intensity is big, need not resemble to embed again the product of commonly using and inlay the iron head, the yield rate height, also easy with the elastomeric assembling of V-arrangement, so can effectively reduce manufacture cost.

Embodiment

Please as shown in Figures 2 and 3, elasticity button described in the utility model comprises V-arrangement elastomer 1 and protruding grain 2.Wherein:

Described V-arrangement elastomer 1 is formed by steel wire bending, and the one end bends out a cutting graftage part 11, and this cutting graftage part 11 can be a direct rod shape, also can be bent with the V-arrangement projection as shown in FIG., to increase the grafting steadiness.

Described protruding grain 2 is provided with spliced eye 21, in order to the cutting graftage part 11 of grafting V-arrangement elastomer 1, thereby makes both constitute a complete elasticity button.

In use, as shown in Figure 4, this elasticity button is arranged in the inside and outside

sleeve pipe

3,4 that can stretch relatively, its protruding grain 2 through holes 31 from inner sleeve 3 stretch out, the other end of its V-arrangement elastomer 1 then is resisted against on the opposite side inwall of inner sleeve 3, thereby makes protruding grain 2 keep stretching out outside the through hole 31 of inner sleeve 3; When one of them positioning hole 41 on the outer sleeve 4 was relative with protruding 2, this protruding grain 2 promptly stretched in this positioning hole 41, thereby inside and outside

sleeve pipe

3,4 is fixed; And when in the positioning hole 41 that protruding grain 2 fixes at different heights, can make inside and

outside sleeve pipe

3,4 Telescopic Fixed is different length.

The V-arrangement elastomer 1 of the foregoing description is because for the cross section forms for circular steel wire bending, when therefore fixing is in columniform inner sleeve 3, but support in the maximum diameter place of inner sleeve 3 inwalls, thereby make support firm.And when in the inner sleeve that fixes at square cylinder, then the elastomeric end of V-arrangement easily slides in the inwall of inner sleeve, thereby makes support built on the sand.

For solving the unsteady problem of support in the inner sleeve of square cylinder, can be shown in Fig. 5,6, it is second embodiment of the present utility model, this embodiment's elasticity button comprises V-arrangement elastomer 1 ' and protruding grain 2 equally, and this V-arrangement elastomer 1 ' the other end be bent with the U-shaped clamping part 12 vertical with this V-arrangement ', all the other structures are then identical with first embodiment.

This embodiment in use, as shown in Figure 7, described elasticity button be arranged at square inside and outside sleeve pipe 3 ', 4 ' in, its protruding grain 2 stretch out inner sleeve 3 ' through hole 31 ' outer, and fix outer sleeve 4 ' one of them positioning hole 41 ' in, V-arrangement elastomer 1 ' clamping part 12 ' then be resisted against inner sleeve 3 ' the opposite side inwall on, because its clamping part 12 ' perpendicular with the V-arrangement place, and with inner sleeve 3 ' in addition side inwall parallel, thereby make the firm support of this elasticity button in inner sleeve 3 ' in, and can slippage.

Again as shown in Figure 8, it is the 3rd embodiment of the present utility model, this embodiment is improved on the basis of first embodiment's elasticity button, promptly fix a perpendicular clamping part 5 again at the other end of described V-arrangement elastomer 1, when being fixed in this elasticity button in the inner sleeve, because this clamping part 5 is parallel with the inner sleeve inwall that is contacted, so firm support, do not have the defective of slippage.
