Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a spring and a spring mattress using the spring. Background Art

[0002] Spring mattresses are commonly used mattresses with advantages such as good elasticity and good load-bearing capacity. The core of a spring mattress is composed of springs, and existing metal springs are prone to problems such as spring collapse and deformation, steel wire breakage, and noise. Currently, rubber springs are usually used to replace metal springs, but the current rubber springs usually have problems such as not being able to take into account elasticity, shock absorption, and support.

[0003] Therefore, based on the above problems, it is necessary to design a new spring structure so as to have sufficient load-bearing capacity and elastic performance while meeting the shock absorption requirements. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide a spring and a spring mattress using the same. The spring of the utility model has good elasticity, sufficient load-bearing capacity and deformation resistance; the spring can be used to prepare a mattress so that the mattress has good shock absorption and can prevent the mattress from collapsing.

[0007] Preferably, the elastic body is an internal hollow structure. When the spring is squeezed, the elastic body deforms under the action of pressure and squeezes the air inside it, so that the spring obtains better elastic performance under the joint action of the elastic body and the internal gas.

[0008] Furthermore, the elastic body is an axisymmetric body, which can make the spring more evenly stressed and strengthen the support of the spring, thereby improving its durability.

With such a design, when the upper and lower ends of the spring are squeezed at the same time, the contact surface between the spring and the force-applying body changes from small to large, thereby enhancing the elasticity of the spring.

[0010] Furthermore, the upper part of the elastic body and the lower part of the elastic body are symmetrically arranged.

[0011] Furthermore, the shock absorbing platform includes an upper shock absorbing platform, a middle shock absorbing platform and a lower shock absorbing platform; the upper shock absorbing platform is arranged at equal intervals on the upper part of the elastic body, the middle shock absorbing platform is arranged around the middle part of the elastic body; the lower shock absorbing platform is arranged at equal intervals on the lower part of the elastic body. The stepped shock absorbing platform is arranged outside the elastic body, so that the acting force can be decomposed layer by layer, thereby achieving the effect of shock absorption and pressure release.

[0012] Furthermore, the side width of the upper shock absorbing platform gradually increases from bottom to top; the side width of the lower shock absorbing platform gradually increases from top to bottom, further enhancing the shock absorbing and pressure releasing effect. In addition, the spring can play a certain buffering role when being squeezed to avoid damage to the spring.

[0013] Furthermore, the upper shock absorbing platform and the lower shock absorbing platform are provided with multiple layers.

[0014] Preferably, the upper shock-absorbing platform on the upper part of the elastic body is distributed in a stepped shape from bottom to top; and the lower shock-absorbing platform on the lower part of the elastic body is distributed in a stepped shape from top to bottom.

[0015] Preferably, the upper shock absorbing platform has three layers; the lower shock absorbing platform has three layers.

[0016] Furthermore, the width of the spring is 4-11 cm; the height of the spring is 4-10 cm.

[0017] Preferably, the width of the spring is 7 cm; the height of the spring is 6 cm.

[0018] The utility model also provides a spring mattress prepared from the springs.

[0019] Through the above design, the utility model has the following technical effects:

[0021] (2) The shock absorbing platform is arranged in a stepped shape so that the force of the extrusion spring can be decomposed layer by layer, thereby improving the shock absorbing and pressure releasing effect.

[0022] (3) The elastomer is set as an internal hollow structure, so that the spring can obtain better elastic performance under the joint action of the elastomer and its internal gas. BRIEF DESCRIPTION OF THE DRAWINGS

With such a design, when the upper and lower ends of the spring are squeezed at the same time, the contact surface between the spring and the force-applying body increases from small to large, thereby enhancing the elasticity of the spring.

[0039] Specifically, the upper part of the elastic body and the lower part of the elastic body are symmetrically arranged.

[0040] Specifically, the shock absorbing platform includes an upper shock absorbing platform, a middle shock absorbing platform and a lower shock absorbing platform; the upper shock absorbing platform is arranged at equal intervals on the upper part of the elastic body, the middle shock absorbing platform is arranged around the middle part of the elastic body; the lower shock absorbing platform is arranged at equal intervals on the lower part of the elastic body.

[0060] Specifically, the elastomer is an internally hollow structure. When the spring is squeezed, the elastomer is deformed under the action of pressure and squeezes the air inside it. Under the joint action of the elastomer and the internal gas, the spring obtains better elastic performance.
