Abstract
The utility model discloses a kind of spring, is characterized in that, including spring body, spring body is formed by spring steel wire spiral surrounding, be it is characterized in that：The two ends of the spring steel wire bend towards the central axis of spring and are extended, and offer coiling groove on the two ends of the spring steel wire, also include limit rope, and the two ends difference coiling of the limit rope is in two coiling grooves.The purpose of this utility model is to prevent spring from being stretched and the situation of generation permanent deformation by transition, to ensure the normal service life of spring.
Description
Technical field
This utility model is related to a kind of spring.
Background technology
Extension spring is that a kind of machinery stores power structure, extensively applies in modern industry, but existing extension spring, bag
The spring body and the hook spring body located at spring body two ends for including one is formed by metal wire rod curling spiral superposition
Hollow cylinder, its operation principle are axially stretched in hollow cylinder, and spring produces reverse contraction power and realizes its function.
The restricted application of cylindrical extension spring, higher to space requirement, for the field for leveling off to plane that some spaces are long and narrow
Close and cannot use, therefore occur in that planar stretch spring.For extension spring, just can be thorough by which as long as the power for using is enough big
Pull open, if but after spring is repeatedly opened, especially for planar stretch spring, easily pulled loose after multi-drawing,
Cause spring not receiving length during pulling force also elongated, affect to use.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of spring, prevents spring from being stretched and produced by transition
The situation of permanent deformation, to ensure the normal service life of spring.
For achieving the above object, this utility model provides following technical scheme：
A kind of spring, including spring body, spring body is formed by spring steel wire spiral surrounding, be it is characterized in that：The bullet
The two ends of spring steel wire towards spring central axis bending and be extended, offer on the two ends of the spring steel wire around
Volume groove, also includes limit rope, and the two ends difference coiling of the limit rope is in two coiling grooves.
By above-mentioned technical proposal, steel wire rope can effectively limit spring body by the length dimension of drawstring, so as to effective
Prevent spring body by the situation of excessive drawstring, it is ensured that the normal service life of spring；Winding groove is available for limit rope two
The stable coiling at end, it is therefore prevented that when limit rope coiling is on spring steel wire, along the situation of spring steel wire axial movement；Work as limit rope
In coiling groove during the different length of coiling, the effective spacing length of limit rope can be adjusted, so as to realize spring body
Carry out different degrees of draw high, improve motility of the present utility model.
Preferably, through hole is offered in the coiling groove described in two.
By above-mentioned technical proposal, when the two ends coiling by limit rope is in coiling groove, first by the two ends of limit rope point
Not Chuan Guo through hole, then carrying out coiling, can so lift the stability that limit rope is wound in coiling groove, on the contrary i.e. limit rope
The situation of skidding, to play stable position-limiting action to spring body.
Preferably, the limit rope is steel wire rope.
By above-mentioned technical proposal, deformation can both have been freeed by steel wire rope, and the structural strength of itself is higher, that is, work as spring
During this compression of body, steel wire rope can occur corresponding deformation, therefore not interfere with the normal compression of spring body.
Description of the drawings
The schematic diagram of the spring that Fig. 1 is provided for this utility model embodiment；
The schematic diagram of the spring body that Fig. 2 is provided for this utility model embodiment；
Another schematic diagram of the spring body that Fig. 3 is provided for this utility model embodiment.
Specific embodiment
This utility model spring is further described by Fig. 1 to Fig. 3.
A kind of spring, including spring body 1, spring body 1 is formed by spring steel wire spiral surrounding, i.e., spring body 1 is in
Hollow cylindrical, the two ends of the spring steel wire are towards central axis bending and extended, the spring steel wire of spring
Two ends on offer coiling groove 2, also include limit rope 3, the two ends difference coiling of the limit rope 3 is in two coiling grooves
In 2.
Further, through hole 4 is offered in the coiling groove 2 described in two.
Further, the limit rope 3 is steel wire rope.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
Claims (3)
