Labor-saving reset structure forfurniturepress rebound opening and closing

Abstract

The invention relates to a labor-saving reset structure forfurniture press rebound opening and closing. The labor-saving reset structure includes a moving sliding rail and a fixed sliding rail, a moving part is arranged on the moving sliding rail, a press rebound device is arranged on the fixed sliding rail, the press rebound device includes a rebound bracket, a push element, a sliding element anda lever assembly, the push element is positioned and / or slides on the rebound bracket, and the sliding element is arranged on the push element in a sliding mode and connected with the lever assembly;when the moving sliding rail is opened, the pressing function is produced, and the push element and / or the sliding element are driven to slide on the rebound bracket in a rebounding mode, so as to realize that the moving sliding rail is slidably opened on the fixed sliding rail in a pressing and rebounding mode;a reset function fitting part is arranged on the moving part; and the moving part and / or the reset function fitting part act when the moving sliding rail is closed or opened for a certain stroke and drive the lever assembly to move on the rebound bracket, and when the lever assembly moves, the push element and / or the sliding element are driven to slide on the rebound bracket in a resetting mode to positionto a terminal initial position. Thelabor-saving reset structure forfurniturepress rebound opening and closinghas high practicability through the improvement of the structure.

Description

technical field [0001] The invention relates to a labor-saving reset structure for pressing and rebounding opening and closing of 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 t...

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, 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. At the same time, it is inconvenient for users to use, and the reset structure is complicated, and there is an unstable phenomenon during use.
