Abstract

The utility model discloses a self -limiting spring, including the spring body, the inside integrated into one piece of spring body has two spacing rings of company of colluding each other, and the spacing ring is buckled by the inside extension in the head and the tail both ends of spring body and is formed, but is used for the one end relative movement of the company of colluding on two spacing rings, and the moving direction of spacing ring is on a parallel with the axial lead of spring body, the utility model provides a when self -limiting spring, spring body took place deformation down in the effect tensile or compression force, relative movement thereupon held in company of colluding each other of two spacing rings, and maxmizing deformation is measured when the tip counterbalance, and messenger elastic deformation keeps at suitable within range, can guarantee the stability of spring elasticity performance, avoided the elastic break -down that the excessive application of force led to the fact.

Description

A kind of from limit spring

Technical field

The utility model relates to spring structure design field, in particular to one from limit spring.

Background technology

Spring is a kind of mechanical component utilizing elasticity to carry out work, by generation deformation when force-extension or compression, original state is recovered again after removing external force, along with the development of industrial age, what spring was more and more is used in various elastomeric component, make the function of various mechanism more powerful, use convenient.

But in the use procedure of spring, meeting Shortcomings part, when applying suitable reactive force on spring, and after reactive force removes, spring can recover original state,, the power many times applied on spring is uncontrollable, and reactive force is often beyond the elastic range of spring itself, make spring cannot recover original state after the distortion that is stretched, cause elastic failure, can not reuse, bring loss.

In sum, how to ensure the stability of spring performance, avoid excessively force to cause elastic force to lose efficacy, become the technical problem that those skilled in the art are urgently to be resolved hurrily.

Practical novel content

The purpose of this utility model is to provide a kind of from limit spring, it is possible to ensure the stability of spring performance, and the elastic force that avoiding excessively exerts a force causes lost efficacy.

For solving the problems of the technologies described above, the utility model provides following technical scheme:

A kind of from limit spring, comprise spring body, one-body molded two the spacing rings having the company of hook mutually of described spring body interior, described spacing ring is bent by the head and the tail inward at both ends extension of described spring body, on two described spacing rings for one end of the company of hook can relative movement, and the travel direction of described spacing ring is parallel to the axial line of described spring body.

Preferably, described spacing ring is bar shaped ring, and length is less than the natural length(of wool) of described spring body.

Preferably, two described spacing ring companies of hook up and down.

Preferably, two described spacing rings are separated setting up and down for one end that hook connects mutually.

Preferably, any one of spacing ring is arranged at the mid-way of another spacing ring for one end of the company of hook.

Provided by the utility model from limit spring, comprise spring body, one-body molded two the spacing rings having the company of hook mutually of spring body interior, spacing ring is bent by the head and the tail inward at both ends extension of spring body, can relative movement for one end of the company of hook on two spacing rings, and the travel direction of spacing ring is parallel to the axial line of spring body, spring body stretch or force of compression effect under there is deformation time, the even end relative movement thereupon of the mutual hook of two spacing rings, largest deformation amount is reached when end offsets, elastic deformation is made to remain in suitable scope, the stability of spring performance can be ensured, avoid the elastic failure excessively exerting a force and causing.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, it is briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is provided by the utility model from limit spring structural representation.

Embodiment

Core of the present utility model is to provide a kind of from limit spring, it is possible to ensure the stability of spring performance, and the elastic force that avoiding excessively exerts a force causes lost efficacy.

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.

It is provided by the utility model from limit spring structural representation incorporated by reference to Fig. 1, Fig. 1.

One provided by the utility model is from limit spring, comprise spring body 1, inner one-body molded two the spacing rings 2 having the company of hook mutually of spring body 1, spacing ring 2 is bent by the head and the tail inward at both ends extension of spring body 1, on two spacing rings 2 for one end of the company of hook can relative movement, and the travel direction of spacing ring 2 is parallel to the axial line of spring body 1.

Provided by the utility model from limit spring, spring body 1 stretch or force of compression effect under there is deformation time, the even end relative movement thereupon of the mutual hook of two spacing rings 2, largest deformation amount is reached when end offsets, deformation is made to remain in suitable scope, the stability of spring performance can be ensured, avoid the elastic failure excessively exerting a force and causing.

In specific embodiment of the utility model, spacing ring 2 in limit spring is bar shaped ring, and length is less than the natural length(of wool) of spring body 1, preferably, two spacing ring about 2 companies of hook, the hook of following the mentioned spacing ring 2 being positioned at top connect end for its bottom, the hook being positioned at the spacing ring 2 of lower section connects end for its top, when the lax state of spring, when the hook of spacing ring 2 being positioned at lower section connect end be overlapped on the spacing ring 2 that is positioned at top bottom time, it is pressure limit spring from limit spring, when the hook of the spacing ring 2 being positioned at lower section connects the top that end is supported in the spacing ring 2 being positioned at top, or the hook of spacing ring 2 being positioned at top connect end be butted on the spacing ring 2 that is positioned at lower section bottom time, it is pulling force limit spring from limit spring.

Preferably, two spacing rings 2 are separated setting up and down for one end of the company of hook mutually, and any one spacing ring 2 is arranged at the mid-way of another spacing ring 2 for one end of the company of hook, it is achieved that pressure and pulling force simultaneously spacing, effectively prevent the elastic failure excessively exerting a force and causing.

It is described in detail from limit spring provided by the utility model above, applying specific case herein principle of the present utility model and enforcement mode to have been set forth, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping. Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, it is also possible to the utility model carries out some improvement and modification, these improve and modify in the protection domain also falling into the utility model claim.
