Abstract

The utility model relates to a mobile phone slide rail folded type flat wire torsion spring, which is formed by curling a flat metal wire; the flat metal wire has a transverse width and a vertical width smaller than the transverse width, it is curled transversely; the central section of the torsion spring is curled into a scroll spring; and both ends of the flat metal wire is extended out to form two feet after forming a torsion spring; the end of the two feet are bent into hooks. The utility model achieves the advantages of high output, low cost, short center distance and long service life.

Description

The mobile phone slide rail is folded shape lenticular wire torsion spring

Technical field

The utility model relates to spring, relates in particular to the folded shape lenticular wire torsion spring of a kind of mobile phone slide rail.

Background technique

General torsion spring has moon bending spring, snakelike torsion spring, M shape torsion spring, but the production technology of these torsion springs is cumbersome, and cost is higher, and the life-span of general moon camber, snake type, M type spring substantially 5-10 ten thousand times, working life is shorter.

The model utility content

The utility model provides a kind of mobile phone slide rail to fold shape lenticular wire torsion spring at the above-mentioned defective of prior art, to improve the working life of torsion spring.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of mobile phone slide rail is folded shape lenticular wire torsion spring, circumnutate by a lenticular wire wire and to form, the lenticular wire wire has horizontal width and vertical width, horizontal width is greater than vertical width, the lenticular wire wire is along laterally circumnutating, the torsion spring middle part circumnutates into the whirlpool spring, and the lenticular wire wire extends bipod to both sides after circumnutating into the whirlpool spring, and the bipod end is bent to form hook.

Preferably, be welded with rivet on the described hook.

Preferably, described rivet is welded on the homonymy or the heteropleural of hook.

Beneficial effect: but the utility model once-through has the advantage that output height, cost are low, centre distance is short, and can reach more than 200,000 times working life.A rivet is welded at torsion spring two respectively, can save the time of assembling.

Embodiment

Below in conjunction with embodiment the utility model is described in further detail.

Referring to shown in Figure 1, the folded shape lenticular wire torsion spring 10 of the utility model mobile phone slide rail is to be circumnutated by a lenticular wire wire to form, the lenticular wire wire has horizontal width and vertical width, set horizontal width greater than vertical width, the lenticular wire wire is along laterally circumnutating, the torsion spring middle part circumnutates into whirlpool spring 1, and the lenticular wire wire extends bipod 2 to both sides after circumnutating into the whirlpool spring, and the bipod end is bent to form hook 3.

Referring to shown in Figure 2, all be welded with a rivet 4 on each hook.

As preferred implementation of the present utility model, two rivets can be welded on the homonymy of hook, also can be welded on the heteropleural of hook.

Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail the utility model, for the personage who is familiar with this type of skill, according to the above description, may do part change and modification to this specific embodiment, its essence does not detach the spiritual category person of the utility model, all should be included in the claim of this case suitable first Chen Ming.
