Abstract
A kind of restricted type compression spring, including cored screw spring body, one end of the spring body is provided with the first fixed panel, the other end is provided with the second fixed panel, and the interior diameter for offering the first circular hole circular hole on first fixed panel and being provided with the embedded spring body the first hollow cylinder consistent with the interior diameter of the first circular hole limits bar；The interior diameter that offers the second circular hole on second fixed panel and be provided with the embedded spring body the second hollow cylinder consistent with the interior diameter of the second circular hole limits bar；First hollow cylinder limits bar and is embedded in the second hollow cylinder restriction bar and slides in which.Restricted type compression spring of the present utility model, is provided with restriction bar, can prevent excess compression of the spring in compression process from damaging spring, extend spring service life.
Description
Technical field
This utility model is related to a kind of spring, more particularly to a kind of restricted type compression spring.
Background technology
Compression spring is subject to the helical spring to pressure, has certain gap between the circle and circle of compression spring, when receiving
To spring contraction deformation during external applied load, deformation energy is stored, produce reverse expansionary force.But existing cylinder hollow compression spring does not have
There is protection device, be frequently present of excess compression, so cause spring to reduce, too fast, impact service life is lost.
Utility model content
In order to solve the above problems, this utility model provide a kind of can be with limited spring excess compression protecting the limit of spring
Type compression spring processed.
A kind of restricted type compression spring, including cored screw spring body, one end of the spring body is provided with first
Fixed panel, the other end are provided with the second fixed panel, offer the first circular hole and be provided with embedding on first fixed panel
Enter the first hollow cylinder in the spring body and limit bar, first hollow cylinder limits the interior diameter and the first circular hole of bar
Interior diameter is consistent；The second circular hole the second sky being provided with the embedded spring body is offered on second fixed panel
Heart cylinder limits bar, and the interior diameter that second hollow cylinder limits bar is consistent with the interior diameter of the second circular hole；Described first is empty
Heart cylinder limits bar and is embedded in the second hollow cylinder restriction bar and slides in which.
It is the length when spring body is compressed that first hollow cylinder limits the length of bar.
It is the length when spring body is compressed that second hollow cylinder limits the length of bar.
Restricted type compression spring of the present utility model, is provided with restriction bar, can prevent mistake of the spring in compression process
Degree compression damages spring, extends spring service life.
Description of the drawings
Fig. 1 is restricted type compression spring structural representation of the present utility model；
Fig. 2 is restriction bar decomposition texture schematic diagram in restricted type compression spring of the present utility model；
Fig. 3 is the first fixed panel planar structure schematic diagram in restricted type compression spring of the present utility model；
Fig. 4 is the second fixed panel planar structure schematic diagram in restricted type compression spring of the present utility model.
Specific embodiment
In order to be better understood from this utility model, this utility model is described below in conjunction with the accompanying drawings in detail.
As illustrated in fig. 1 and 2, a kind of restricted type compression spring of the present utility model, including cored screw spring body 1, institute
The one end for stating spring body 1 is provided with the first fixed panel 2, and the other end is provided with the second fixed panel 3, as shown in figure 3, described
The first hollow cylinder for offering the first circular hole 6 on first fixed panel 2 and being provided with the embedded spring body 1 limits bar
4, it is consistent with the interior diameter of the first circular hole 6 that the first hollow cylinder limits 4 interior diameter of bar；As shown in figure 4, second fixed panel
The second hollow cylinder for offering the second circular hole 7 on 3 and being provided with the embedded spring body 1 limits bar 5, the second open circles
The interior diameter that post limits bar 5 is consistent with the interior diameter of the second circular hole 7；First hollow cylinder limits bar 4 and is embedded in described second
Hollow cylinder is limited in bar 5 and is slided in which.
Preferably, the length that first hollow cylinder limits bar 4 is the length when spring body 1 is compressed.
Preferably, the length that second hollow cylinder limits bar 5 is the length when spring body 1 is compressed.
Restricted type compression spring of the present utility model, is provided with restriction bar, can prevent mistake of the spring in compression process
Degree compression damages spring, extends spring service life.
The above, only this utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any those familiar with the art in the technical scope that this utility model is disclosed, according to this practicality
New technical scheme and its utility model design in addition equivalent or change, should all cover in protection model of the present utility model
Within enclosing.
