Elasticity pressing rebound structure

Abstract

Provided is an elasticity pressing rebound structure. The elasticity pressing rebound structure comprises a pressing rebound device, the pressing rebound device comprises at least a rebound support and a pushing element, the pushing element locates and slides on the rebound support, the elasticity pressing rebound structure is characterized in that the rebound support is provided with a steering wheel and a tension spring, the steering wheel locates and rotates on the rebound support, one end of the tension spring is matched with the rebound support, and the other end of the tension spring winds on the steering wheel and is matched with the pushing element; and the pushing element locates and slides on the rebound support through the matched elasticity of the steering wheel and the tensionspring. The elasticity pressing rebound structure, by the improvement of the structure above, has the advantages that the structure is simple and reasonable, the performance is reliable, each component is compactly connected, the service life is long, the manufacturing cost is low, the disassembly and the assembly are quick and convenient, the flexibility is high, the opening and closing processis stable and smooth, force is small and the use range is wide, and the practicability is strong.

Description

technical field [0001] The invention relates to an elastic pressing and rebounding structure. Background technique [0002] Chinese Patent Document No. CN107411385A disclosed a furniture automatic reset press rebound mechanism on April 14, 2017. It includes furniture movable parts, furniture fixed parts, connecting elements and fixed brackets. On the fixed part of the furniture, a pressing rebound device, a telescopic reset device and at least two rotating wheels are provided on the fixed bracket. The pushing element and the telescopic element slide on the fixed bracket respectively, and at least two rotating wheels are set relatively independently and respectively rotate on the fixed bracket. At least two rotating wheels cooperate with each other when rotating to a certain position. Drive connection, the other rotating wheel is driven and connected with the push element; the push element is provided with a swing element, and the fixed bracket is provided with a heart-shape...

AI Technical Summary

Problems solved by technology

This structure must overcome the elasticity of the third elastic element when it is pressed to open, so that the push element can slide and open along the track of the heart-shaped chute. Due to the high elasticity of the third elastic element, the user needs to apply the same force when pressing. As a result, the user must use a large force to press and open the furniture. At the same time, the third elastic element is a compression spring, and its elastic force changes due to the length of compression and extension. Large, it is easy to pop open quickly when the furniture is opened, and it must gradually increase the force to close when it is closed, which affects the user's experience and makes it inconvenient for users to use.
