Description

Compress Spring

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 Compress Spring 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, and the straight line at the beeline place of cross section along opening part to the position of caving in forms kernel of section axis, kernel of section axis and described body central axis project to same plane and intersect.

By adopting technique scheme, the utility model Compress Spring identical with Normal squeezing spring length, they are except two spring ring spacings, the cross section of V-arrangement hatch frame can become the butterfly spring that rigidity is higher at spring-compressed to a certain extent time, under above-mentioned double action, can improve greatly the elastic force of Compress Spring.

The utility model is further set to: the cross section of described metal wire rod is V-shaped.

The utility model is further set to: the cross section of described metal wire rod takes the shape of the letter U.

The utility model is further set to: the cross section of described spring body is symmetrical about described kernel of section axis, and this kernel of section axial projection is vertical with it in the plane time to described body central axis institute.

By adopting technique scheme, make the utility model Compress Spring there is more compression volume by the butterfly spring of the cross section formation of V-arrangement or U-shaped hatch frame.

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 utility model Compress Spring has advantages of the spring force of significantly improving.

Embodiment

Referring to figs. 1 through Fig. 5, Compress Spring of the present utility model is described further.

As shown in Figure 1 to Figure 2, for the utility model provides following examples: a kind of Compress Spring, comprise the spring body 11 with body central axis 3, spring body 11 is superimposed as cylindrical helix structure by a metal wire rod around body central axis 3 is curling, comprise a plurality of spiral rings, be connected and have spacing between two spiral rings, the cross section 21 of described metal wire rod is V-arrangement, and the straight line at beeline (i.e. the distance at a place by figure in to the b place) place of cross section 21 along opening part to the position of caving in forms kernel of section axis 4, the cross section 21 of described spring body 11 is about described kernel of section axis 4 symmetries, kernel of section axis 4 and described body central axis 3 project to same plane and intersect.

As shown in Figure 3 and Figure 4, be the second embodiment of the present utility model, the Compress Spring described in this embodiment is except V-arrangement cross section 2 openings of spring body 12 are dorsad axle center, and other are all identical with embodiment one.

As shown in Figure 5, be the third embodiment of the present utility model, the spring body cross-section of the Compress Spring described in this embodiment is the U-shaped similar to V-arrangement, all the other structures are all identical with embodiment one.

As the further improvement of above-mentioned three kinds of model utilitys, described Compress Spring can be used X-shaped cross section, and this structure is also to use embodiment one principle, increases rigidity and the elasticity of spring body on embodiment one basis by strengthening elastic material cross section.

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 the U-shaped cross-section in embodiment three also can be used in embodiment two; spring body also can arrange the polygon bodily form or ellipse, and these also should be considered as protection domain of the present utility model.
