CN200961657Y - Composite spring - Google Patents

Abstract

The utility model discloses a composite spring, with low foaming sponge filled in the ordinary spring. The elasticity of the composite spring of the utility model is determined by the deformation of the ordinary spring and the low foaming sponge filled, with the elasticity of the spring greatly enhanced in composite. Furthermore, the deformation of the composite spring is recovered by the elasticity of the ordinary spring combined with the elasticity of the low foaming sponge, which retains the elasticity of the composite spring, prevents deformation and improves utilization.

Description

A kind of complex spring

Technical field

The utility model relates to the technical field of spring, refers in particular to a kind of spring that is composited.

Background technique

Common spring 1 as shown in Figure 1, its elastic force size depends on the deformation of spring 1 itself fully, so, the elasticity of spring 1 a little less than; And the deformation of spring 1 itself recovers by the elastic force effect of spring 1 fully, and elastic fatigue appears in spring 1 easily, follows the string even is out of shape, and influences using effect.

The model utility content

The purpose of this utility model is to provide a kind of good springiness, on-deformable complex spring.

To achieve these goals, solution of the present utility model is:

A kind of complex spring is filled low foam sponge in common spring.

After adopting said structure, the utility model is filled low foam sponge in common spring, because low foam sponge has high elasticity and certain intensity, so, the elastic force size of complex spring is decided by the deformation of common spring itself and the low foam sponge of filling, the elasticity of compound rear spring strengthens greatly, and, the deformation of complex spring is to be used for recovery by the elastic force effect of common spring itself in conjunction with the elastic force of low foam sponge, guaranteed the elasticity of complex spring, avoid distortion, using effect promotes.

Description of drawings

Fig. 1 is the structural representation of common spring;

Fig. 2 is a structural representation of the present utility model.

Embodiment

As shown in Figure 2, the complex spring of the utility model announcement is to fill low foam sponge 2 in common spring 1.Because low foam sponge 2 has high elasticity and certain intensity, the elastic force size that makes complex spring is decided by the deformation of common spring 1 itself and the low foam sponge 2 of filling, the elasticity of compound rear spring strengthens greatly, and, the deformation of the utility model complex spring is to be used for recovering in conjunction with the elastic force that hangs down foam sponge 2 by common spring 1 elastic force effect own, guaranteed the elasticity of complex spring, avoided distortion, using effect promotes thus.

Claims (1)

1, a kind of complex spring is characterized in that: fill low foam sponge in common spring.
