Abstract
The utility model discloses a tension spring which comprises a distortion body, an arc hook outwards extending and bending from one end of the distortion body along the axial direction of the distortion body, and a suspension end outwards extending from the other end of the distortion body along the axial direction of the distortion body, wherein the distortion body is spiral and is provided with spiral ring bodies, the spiral ring bodies are abutted against each other and have no gap when not being tensioned; and the tail end of the suspension end is provided with a spiral suspension hook. The tension spring has simple structure, less susceptible distortion after the stress, and stable suspension.
Description
Technical field
The utility model relates to a kind of spring structure, particularly a kind of spring structure of realizing telescopic spring by spring is stretched.
Background technique
Early stage spring just forms the bending of rubber-like object, and only just directly utilizes the elastic force of this object, makes it do a to-and-fro motion on limited deflection distance.
In addition, because the restriction of early stage this body structure of spring, it can't carry out just can being out of shape and damaging in case stretch axially outwards to stretch to spring, and the face of early stage spring structure two end in contact can only be the plane or need certain surface of contact could follow the use of getting well, application is limited.
The model utility content
In view of the foregoing, main purpose of the present utility model is to provide a kind of outwards axial tension, and stretch can't deformed damaged after stressed extension spring.
To achieve these goals, the utility model has adopted following technical proposals:
Described a kind of extension spring comprises a distortion body, extend an arc shaped hook from this distortion body one end and along this distortion body shaft to outside bending, and this distortion body the other end and hang end to stretching out along this distortion body shaft certainly, this hangs the end end and has a spiral hook.
Extension spring described in the utility model is simple in structure, and is not easy distortion after stressed, and hangs stable.
Description of drawings
Fig. 1 is the structural representation of a kind of extension spring described in the utility model.
Embodiment
Come a kind of extension spring described in the utility model is described in further detail below in conjunction with accompanying drawing and specific implementation process.
Shown in Fig. 1, a kind of extension spring described in the utility model comprises a distortion body 10, be outward extended with an arc shaped hook 101 at these distortion body 10 two ends respectively and hang end 102, wherein, described arc shaped hook 101 extends for axially outwards bending from these distortion body 10 1 ends and along this distortion body 10, describedly hangs that to hold 102 be axially to stretch out from these distortion body 10 the other ends and along described distortion body 10.
See Fig. 1, hang end 102 ends at described this and also have a spiral hook 1020, stable when this structure is placed in external object, be not easy to come off.
In addition, described distortion body 10 is shape in the shape of a spiral, and has a plurality of spiral circle bodies 103, this spiral circle body 103 when distortion body 10 is not stretched for and tight no gap; And this described distortion body 10 can be rotated by the metal ring of a long strip and form.
Claims (3)
1. extension spring, it is characterized in that, comprise a distortion body, have respectively at these distortion body two ends an arc shaped hook that extends to outside bending from this distortion body one end and along this distortion body shaft and from this distortion body the other end and along described distortion body shaft to the end that hangs that stretches out, wherein, described distortion body is shape in the shape of a spiral, and has a plurality of and tight gapless spiral circle body.
2. according to the described a kind of extension spring of claim 1, it is characterized in that, hang the end end at described this and have hook.
