CN201310584Y - Multiple-bending-angle distortion spring - Google Patents

Abstract

The utility model discloses a multiple-bending-angle distortion spring which is formed by bending a strip body for multiple times and comprises a first bending part, a second bending part and a third bending part positioned between the first bending part and the second bending part, one end tail of the second bending part is bended to form a bending end, one end tail of the first bending part is provided with a straight-line built-in end, and the first bending part and the second bending part outwards protrude with respect to the third bending part. The multiple-bending-angle distortion spring has simple structure and easy processing and fabricating.

Description

Many knuckle distortion springs

Technical field

The utility model relates to a kind of spring structure, particularly a kind of spring structure with a plurality of knuckles.

Background technique

Early stage spring is just formed by the bending of rubber-like object, just directly utilizes the elastic force of this object to make it do a to-and-fro motion on limited deflection distance.

For above-mentioned, though early stage spring has satisfied people's needs to a certain extent, but, the elastomeric objects that it is just crooked, under some pressure ratios big situation and in some balanced controls, the elastomeric objects of this bending just can't bear these load, and is easy to compressive deformation, even damages.

At present, we use always mostly is spiral helicine spring structure, though the spring load degree height of this kind structure, and return is effective, and for some special constructions, such as in the use of duplicating machine damping and noise reduction, described spiral helicine spring is also inapplicable.

The model utility content

In view of the foregoing, main purpose of the present utility model is to provide in a kind of structure applicable to duplicating machine damping and noise reduction, and can not be out of shape, many knuckle distortion springs simple in structure.To achieve these goals, the utility model has adopted following technical proposals:

Described many knuckle distortion springs are for being formed through repeatedly bending by a long strip body, and have first kink, second kink and the 3rd kink between first kink and second kink on this body, and going out a bending end in the bending of an end of second kink end and from first kink, the one end set terminal that stretches out.

Many knuckle distortion spring structures described in the utility model are simple, and processing and fabricating is easy.

Description of drawings

Fig. 1 is the structural representation of many knuckle distortion springs described in the utility model.

Embodiment

Come many knuckle distortion springs described in the utility model are described in further detail below in conjunction with accompanying drawing and specific implementation process.

Shown in Fig. 1, many knuckle distortion springs described in the utility model are for being formed through repeatedly bending by a long strip body 10, and it comprises first kink 101, second kink 102 and the 3rd kink 103 between this first kink 101 and second kink 102, wherein, one end of described second kink 102 end bending and the end end that goes out a bending end 1020 and described first kink 101 has a linearly set terminal 1010, and described first kink 101 and second kink 102 recessedly go out for outside with respect to the 3rd kink 102 for.

In addition, described long strip body 10 is for adopting metal material.

Claims (1)

1. knuckle more than a kind is out of shape spring, it is characterized in that, comprise a long strip body, and have first kink, second kink and the 3rd kink between first kink and second kink on this body, and forming a bending end and from first kink, the one end set terminal that stretches out in the bending of an end of second kink end.
