Abstract
The utility model discloses the spring of a kind of stretch-proof and compression, including outer spring body, further include the resilient sleeve of parcel spring, further include the outer base for being arranged on outer spring both ends, further include the casing being arranged in outer spring and inner sleeve, further include and be arranged on the inner spring that casing and inner sleeve cross at space, for the outer spring in horn-like, both ends diameter is more than interlude diameter；The lateral surface of the outer base is convex dot shape, and the cross sectional shape of described sleeve pipe and inner sleeve is L-shaped, and the L-shaped inside pipe casing is equipped with lower end interior base, and set upper side is equipped with upper end interior base in the L-shaped.The utility model causes spring to be run on the same axis in compression stretching, will not be distorted deformation, and when compression stretching has maximum spacing, and the collective effect of outer spring and inner spring can recover original-shape faster, it ensure that security when spring uses, service life is more permanent.
Description
Technical field
It the utility model is related to mechanical spring field, the spring of more particularly to a kind of stretch-proof and compression.
Background technology
Spring be it is a kind of utilize elasticity come work machine components.Part is sent out under external force made of elastic material
Raw deformation, restores to the original state, is widely used in various machinery fields again after removing external force.Existing spring is in stretching or in compression
During the phenomenon for breaking or not recovering shape and disalignment occurs, influence customer experience.
Utility model content
The purpose of this utility model is to provide incompressible and stretching the spring that a kind of stability is high, and service life is grown.
What the purpose of this utility model was realized in：A kind of incompressible and stretching spring, including outer spring body, also
Resilient sleeve including wrapping up spring, further includes the outer base for being arranged on outer spring both ends, further includes the set being arranged in outer spring
Pipe and inner sleeve, further include and are arranged on the inner spring that casing and inner sleeve cross at space；
The outer spring is in horn-like, and both ends diameter is more than interlude diameter；The lateral surface of the outer base is convex dot shape；
The cross sectional shape of described sleeve pipe and inner sleeve is L-shaped；The L-shaped inside pipe casing is equipped with lower end interior base；Set upper side in the L-shaped
Equipped with upper end interior base；The inner spring and casing lower bottom base and inner sleeve upper bed-plate are closely coupled.
Compared with prior art, the beneficial effects of the utility model are：Due to the setting of resilient sleeve, elasticity capacity obtains
Greatly enhance；Due to the setting of casing and inner sleeve, spring is subject to guiding role not deviate by axle center in compression stretching；Due to
Inner spring device is provided with the space that crosses of casing and inner sleeve, inner spring device can limit outer spring during work
Elongation and decrement, while can fast quick-recovery original-shape under the collective effect of inner spring and outer spring.Overall structure
Simply, it is easy for installation, and spring operating condition effect is good.
As the preferred solution of the utility model, the L-shaped casing and inner sleeve phase internal buckle form the closed space that crosses.
As the further preferred scheme of the utility model, described sleeve pipe and inner sleeve on the same axis simultaneously can phase interworkings
Close.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein, 1 outer end face, 2 outer bases, 3 outer springs, 4 resilient sleeves, 5 inner springs, 6 casings, 7 inner sleeves, 8 inner sleeve upper bed-plates,
9 casing lower bottom bases.
Embodiment
As shown in Figure 1, a kind of incompressible and stretching spring, including outer spring body 3, further include the elasticity for wrapping up spring
Set 4, further includes the outer base 2 for being arranged on 3 both ends of outer spring, further includes the casing 6 being arranged in outer spring 3 and inner sleeve 7, also wrap
Include and be arranged on the inner spring 5 that casing 6 and inner sleeve 7 cross at space；
Outer spring 3 is in horn-like, and both ends diameter is more than interlude diameter；The lateral surface of outer base 2 is convex dot shape；Casing 6
And the cross sectional shape of inner sleeve 7 is L-shaped；Casing 6 is internally provided with lower end interior base 8；7 upper end of L-shaped inner sleeve is equipped with upper end interior base
9；Inner spring 5 and casing lower bottom base 8 and inner sleeve upper bed-plate 9 are closely coupled.
Above-mentioned casing 6 and 7 phase internal buckle of inner sleeve form the closed space that crosses.
Above-mentioned casing 6 and inner sleeve 7 can simultaneously cooperate on the same axis.
The operation principle of the utility model is described below, and when being compressed, casing 6 and 7 device of inner sleeve play
Guiding role, makes it not deviated in the axle center of compression direction, and inner spring 5 is elongated to maximum, during release the elastic force of inner spring 5 with
The pulling force collective effect of outer spring 3, makes it recover original-shape rapidly.When being stretched, inner spring 5 is compressed to most
Small, the presence of casing 6 and inner sleeve 7 makes it be restricted in the maximum of stretching, the pulling force of inner spring 5 and outer spring 3 during release
Elastic force collective effect, it is recovered original-shape rapidly.So that spring is unlikely to deform, increase security, extending it makes
Use the service life.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can be special to some of which technology
Sign makes some and replaces and deform, these are replaced and deformation is within the protection scope of the present utility model.
