Description

Long-life spring structure for sofa

Technical Field

The utility model relates to a spring especially relates to a long-life spring structure for sofa.

Background

A spring is a mechanical part that works by elasticity. The part made of elastic material deforms under the action of external force and restores to the original shape after the external force is removed. Also used as a "spring". Typically made of spring steel. The spring is of various types, mainly comprises a spiral spring, a volute spiral spring, a plate spring, a special-shaped spring and the like according to the shape, and relates to a spring for a sofa, which is arranged in the sofa.

Patent numbers: CN108679139A discloses a compression spring, which is provided with a first elastic pad between the locking mechanism and the bottom plate, so that the locking mechanism impacts the elastic pad instead of the bottom plate, thereby reducing noise, reducing damage to the bottom plate, and prolonging the service life of the compression spring.

However, the above patents have the following disadvantages: 1. the dustproof and waterproof effect of the spring is not very good, and the normal use of the sofa is influenced, so that improvement is needed. 2. The spring in the sofa is used for a long time, the elasticity is reduced, the shape is contracted, a structure for promoting the shape recovery of the spring is required to be installed to prolong the service life of the spring, the design does not relate to the point, and the improvement is needed.

SUMMERY OF THE UTILITY MODEL
