Abstract
The utility model discloses a kind of Compress Spring, comprise the spring body with body central axis, spring body is mainly formed by stacking around body central axis is curling by a metal wire rod, every superimposed layer shape, big or small identical, it is characterized in that: on the cross section of described metal wire rod, have opening, described cross-sectional openings direction is identical with the flexible direction of spring body, and the utility model Compress Spring has advantages of the spring force of raising.
Description
Technical field
The utility model relates to a kind of spring, and more particularly, it relates to a kind of Compress Spring.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to carry out work, generally with spring steel, makes, and its principle is that deformation occurs under external force, removes after external force and restores to the original state again.The kind complexity of spring is various, by shape, divides, and mainly contains helical spring, spiral spring, leaf spring, heterotypic spring etc.Spring is widely used a kind of elastic element in machinery and electron trade, wherein Compress Spring is most widely used, it is circular that the cross section of Compress Spring spring material used mostly is, at some special occasions, owing to requiring installing space to limit, the Compress Spring of circular cross-section can not produce enough elastic force in fixing length, cannot meet usage requirement.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of Compress Spring that improves compression effectiveness.
For achieving the above object, the utility model provides following technological scheme: a kind of Compress Spring, comprise the spring body with body central axis, spring body is mainly formed by stacking around body central axis is curling by a metal wire rod, every superimposed layer shape, big or small identical, it is characterized in that: on the cross section of described metal wire rod, have opening, described cross-sectional openings direction is identical with the flexible direction of spring body.
The utility model is further set to: the cross section of described metal wire rod is V-shaped.
By adopting technique scheme, when its length is identical with general Compress Spring, when if the thickness of metal wire rod itself is identical, the V-arrangement cross section that the utility model adopts can have more a V-arrangement open space between every two spring rings, in order to increase the compression volume of spring; If when the utility model metal wire rod used is thick, although the decrement of two kinds of springs is identical, cross section of the present utility model is larger, both the rigidity of this spring was larger, made the elasticity of this spring better; Use simultaneously this very the spring in cross section when being subject to some Special Forces, between spring ring, can not be offset.
The utility model is further set to: the cross section of described metal wire rod takes the shape of the letter U.
By adopting technique scheme, U-shaped cross-section place have described V-arrangement cross section outside above advantage, use U-shaped cross-section can be exerted pressure to U-shaped cross-section both sides when spring is compressed to a certain degree, this structure can suitably increase the elastic force of spring.
The utility model is further set to: the cross section of described spring body is symmetrical about described kernel of section axis.
By adopting technique scheme, make the utility model can have larger sectional area.
The utility model is further set to: described spring body is cylindrical.
By adopting technique scheme, spring body is made to the elasticity of cylindrical increase Compress Spring that can be suitable.
In sum, the utlity model has the advantage that improves spring force.

Fig. 2 is Compress Spring embodiment one positive view;
Fig. 3 is Compress Spring embodiment two front view.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model Compress Spring is described further.
As shown in Figure 1 to Figure 2, a kind of Compress Spring, comprise the spring body 1 with body central axis 4, spring body 1 is superimposed as cylindrical helix structure by a metal wire rod around body central axis 4 is curling, comprise a plurality of spiral rings, be connected and have spacing between two spiral rings, the cross section 2 of described metal wire rod is substantially V-shaped, and described cross section 2 opening directions are identical with the flexible direction of spring body 1.
As shown in Figure 3, be the second embodiment of the present utility model, spring body 1 cross section 2 of the Compress Spring described in this embodiment is outside U-shaped, all the other structures are all identical with embodiment one.
The above makes preferred implementation of the present utility model; do not depart from for the person of ordinary skill of the art under the prerequisite of the utility model principle; can also make some modification and improvement; as spring body be arranged to the polygon bodily form or oval build etc. can with some special occasions, these also should be considered as protection domain of the present utility model.
Claims (5)
