Furniture mutelabor-savingpressingand reboundingopening-closing structure

Abstract

The invention provides a furniture mute labor-saving pressing and rebounding opening-closingstructure comprises a pressure rebound device. The pressure rebound device comprises at least a rebound support, a pushing element and a sliding element. The rebound support is provided with a heart-shapedsliding chute, the pushing element is provided with a slipping part, the sliding element is arranged on the pushing element in a sliding modeand connected with the slipping part in a driving mode by a guide part arranged on the sliding element during sliding, the slipping part locates and / or slides along the track of the heart-shaped sliding chute in a sequential direction through the driving of the guide part, and drives the pushing element to slide and extendout of the rebound support during sliding;ananti-collision part is arranged between the rebound support and the pushing element, when extending in a sliding mode,the pushing element is positioned and matched with the rebound support by the anti-collision part in a mutual anti-collision type through theanti-collision part. Through the improvement of the structure, the pressing and rebounding opening-closing structurehasthe characteristics ofsimple and reasonable structure, reliable performance, compact connection between each component, long service life, low manufacturing cost, quick and convenient disassembly and assembly, high flexibility, wide range of use and the like, and the practicability is high.

Description

technical field [0001] The invention relates to a silent and labor-saving press rebound opening and closing structure for furniture. 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...

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 push element will collide with the fixed bracket when it pops up. The oscillating element will collide with the heart-shaped chute, which will cause abnormal noise when the product is in use, and affect the service life of the pushing element, fixing bracket and oscillating element, and the user needs to apply the same force when pressing, resulting in The user must use a large force to press and open the furniture. At the same time, when both opening and closing require simultaneous force, the user must also use a large force to reset and press the rebound mechanism to close the furniture, which affects the user experience. , causing inconvenience to users
