Abstract
The invention discloses a kind of stretch-proof hook spring, the spring includes the resilient sleeve of spring body and package spring, further includes the limit rope being connected with pedestal；The both ends of the spring condensed section is closely connect with pedestal, and the pedestal is closely connect with hook, and the pedestal inner face is equipped with jeans button, and the jeans button connects limit rope.The design make stretch when will not because active force is excessive and make spring and hook junction deform, internal rope limits the maximum tension amount of spring, ensure that spring use when safety, keep its service life more permanent.
Description
Technical field
The present invention relates to mechanical spring field, more particularly to a kind of stretch-proof hook spring.
Background technology
Spring be it is a kind of utilize elasticity come work machine components.The part made of elastic material is sent out under external force
Raw deformation restores to the original state again after removing external force.It is widely used in various machinery fields.Existing hook spring will appear in stretching
The case where being deformed with spring junction there is also the excessive unreducible situation of stretcher strain amount, it is made to influence customer experience.
Invention content
The object of the present invention is to provide prevent from amount of tension from crossing big spring and can not restore and link up with the junction of spring to occur
A kind of stretch-proof hook spring of deformation.
The object of the present invention is achieved like this：A kind of stretch-proof hook spring, the spring include spring body and packet
The resilient sleeve for wrapping up in spring further includes the pedestal being connected with spring, and the pedestal is closely connect with hook, and the pedestal inner face is set
There are the jeans button of protrusion, the jeans button to connect limit rope.
The prior art is compared, the beneficial effects of the present invention are：Pedestal is equipped with for two sections due to spring, links up with directly phase
Connection, avoids and is deformed upon when being connect with spring because active force is excessive, since spring inner is provided with limitation rope, bullet
The maximum that spring stretches has obtained maximum limit, it is made to be unlikely to deform, and to keep elasticity for a long time, the design overall structure is simple,
Using effect is good so that spring service life extends.
It is wavy as the preferred embodiment of the present invention, on the inside of the hook.
As present invention further optimization scheme, two sections of the spring is is comparably loose section among condensed section, institute
Both ends of the spring condensed section is stated to connect with pedestal.
As present invention further optimization scheme, the limit rope material is nylon material.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Wherein, 1 hook inside, 2 hooks, 3 resilient sleeves, 4 pedestals, 5 limit ropes, 6 springs, 7 jeans buttons.
Specific implementation mode
As shown in Figure 1, a kind of stretch-proof hook spring, the spring includes the resilient sleeve 3 of spring 6 and package spring 6, also
Include the pedestal 4 being connected with spring 6, the pedestal 4 is closely connect with hook 2, and 4 inner face of the pedestal is equipped with the I-shaped of protrusion
Button 7, the jeans button 7 connect limit rope 5.
1 is wavy on the inside of above-mentioned hook.
To be comparably loose section among condensed section, 6 both ends condensed section of spring is connect 6 two sections of above-mentioned spring with pedestal 4.
5 material of above-mentioned limit rope is nylon material.
The operation principle of the present invention is described below, and when being stretched, the inside limit rope 5 of spring 6 can be stretched to
Maximum length controls the amount of tension of spring 6 in turn, while linking up with 2 and not being connected with 6 ontology of spring, with being directly connected to for pedestal 4
So that its junction will not deform, safety is increased, extends its service life.
The invention is not limited in above-described embodiments, on the basis of technical solution disclosed by the invention, the skill of this field
For art personnel according to disclosed technology contents, one can be made to some of which technical characteristic by not needing performing creative labour
A little to replace and deform, these are within the scope of the invention for replacement and deformation.
Claims (4)
