Description
Technical field:
This utility model relates to spring technical field, a kind of new type of compression spring.
Background technology:
Spring is a kind of machine components utilizing elasticity to carry out work, in order to control parts motion, relax impact or vibrations,
Storage or saving energy, the size etc. of measurement power, be widely used in machine, instrument, through conventional two equal height different inner diameters in reality
Compression spring concentric locking collar use together, but between two compression springs easily with respect to mobile cause concentric so that
Obtain compression spring discontinuity equalization to be easy for producing tilt phenomenon, the most not only affect the service behaviour of compression spring, be more easy to make
Compression spring is damaged, and reduces the service life of compression spring.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, concentric all the time and stress
The new type of compression spring of equilibrium.
This utility model solves the scheme of described technical problem: a kind of new type of compression spring, including interior compression spring and
External compression spring, described interior compression spring and external compression spring be distributed and the most equal with one heart, described interior compression spring and external pressure
Contracting spring is respectively equipped with upper plate and lower plate above and below, is provided with the ring of fit between described interior compression spring and external compression spring
Shape sleeve and convex ring pole, described annulus inwall and interior compression spring outer wall matched in clearance and outer wall and external compression spring inwall
Matched in clearance, is matched in clearance between described annulus and convex ring pole, and described annulus can be along the outer wall of convex ring pole
Slide downward, described annulus is fixed on upper plate, and described convex ring pole is fixed in lower plate.
The inside and outside barrel of described annulus is equipped with polytetrafluorethylecoatings coatings, and the outer wall of described convex ring pole is provided with poly-four
Fluorothene coating.
Distance A of described upper plate bottom surface to convex ring pole upper surface is more than interior compression spring and the maximum compression of external compression spring
Amount, above described lower plate, distance B to annulus lower surface is more than interior compression spring and the maximum compressibility of external compression spring.
Prominent effect of the present utility model is: so that interior compression spring and external compression spring concentric all the time and be subject to
Power equalizes, it is ensured that the performance of spring, improves service life, practical, is worthy to be popularized.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
As it is shown in figure 1, a kind of technical scheme of this utility model offer: a kind of new type of compression spring, including interior compression spring 1
With external compression spring 2, described interior compression spring 1 and external compression spring 2 be distributed and the most equal with one heart, described interior compression spring 1
Upper plate 3 and lower plate 4 it is respectively equipped with above and below, between described interior compression spring 1 and external compression spring 2 with external compression spring 2
It is provided with annulus 6 and the convex ring pole 5 of fit, described annulus 6 inwall and interior compression spring 1 outer wall matched in clearance and outer wall
With external compression spring 2 inwall matched in clearance, it is matched in clearance between described annulus 6 and convex ring pole 5, described annulus 6
Can be along the outer wall slide downward of convex ring pole 5, described annulus 6 is fixed on upper plate 3, and described convex ring pole 5 is fixed on down
On plate 4.
The inside and outside barrel of described annulus 6 is equipped with polytetrafluorethylecoatings coatings, and the outer wall of described convex ring pole 5 is provided with poly-
Tetrafluoroethene coating.
Distance A of described upper plate 3 bottom surface to convex ring pole 5 upper surface is more than interior compression spring 1 and the maximum of external compression spring 2
Decrement, described lower plate 4 above to annulus 6 lower surface distance B more than interior compression spring 1 and external compression spring 2
Big decrement.
This utility model when in use so that interior compression spring 1 and external compression spring 2 concentric all the time and
Stress equalization, it is ensured that the performance of spring, improves service life, practical, is worthy to be popularized.
Finally, embodiment of above is merely to illustrate this utility model, and is not limitation of the utility model, relevant skill
The those of ordinary skill in art field, in the case of without departing from spirit and scope of the present utility model, it is also possible to make various change
Changing and modification, the technical scheme of the most all equivalents falls within category of the present utility model, patent protection model of the present utility model
Enclose and should be defined by the claims.
