Problems solved by technology

[0003] Springs often make noise when they are working. The noise is caused by vibration, so no matter what material the spring returns to its original state after deformation, there will be different degrees of noise. For example, the springs used in mattresses are usually made of The steel wire is bent in one piece, and the noise generated during compression and rebound is relatively large, which often affects people's rest

Embodiment Construction

[0015] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0016] see figure 1 , a sound-absorbing spring according to a preferred embodiment of the present invention includes a spring body 1, the spring body 1 includes several coils, and a compression bag 2 is provided inside the spring body 1, and the compression bag 2 is made of flex-resistant rubber material. The softness of the rubber is relatively high, which can adapt to more times of bending and rebounding. The two ends of the compression bag 2 are fixedly connected with the coils. The side wall of the compression bag 2 is provided with four openings 4, respectively surrounding the compression bag 2. One week, the opening 4 is in the shape of a "ten". In the original sta...

Abstract

The invention relates to a mechanical hardware machine, in particular to a noise reduction spring. The noise reduction spring comprises a spring body. The spring body comprises a plurality of helixes. A compression bag is arranged in the spring body. The two ends of the compression bag are fixedly connected with the helixes. Cross-shaped openings are formed in the side wall of the compression bag. The springback speed of the spring can be reduced, the vibration frequency is reduced, and therefore noise is lowered.

Description

technical field [0001] The invention relates to a mechanical hardware appliance, in particular to a sound-absorbing spring. Background technique [0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of an external force, and returns to its original shape after the external force is removed. There are many kinds of springs, divided by shape, mainly including coil springs, scroll springs, leaf springs, special-shaped springs and so on. The most common is the cylindrical coil spring, which has a simple structure, is easy to manufacture, and is widely used. [0003] Springs often make noise when they are working. The noise is caused by vibration, so no matter what material the spring returns to its original state after deformation, there will be different degrees of noise. For example, the springs used in mattresses are usually made of The steel wire is bent in one piece, and the noise generated during com...
