Labor-saving mute pressing rebound opening and closing device for furniture

Abstract

The invention discloses a labor-saving mute pressing rebound opening and closing device for furniture. The device comprises a rebound bracket, a pushing element and a pressing element, and a clip-shaped groove is formed in the rebound bracket; a sliding shaft part is arranged on the pushing element; the pressing element elastically stretches out and draws back to slide on the pushing element and / or the rebound support in a limited mode and acts and drives the sliding shaft part to be located and / or slide in the track of the concentric-square-shaped groove in the sequence direction in the sliding process. A lever assembly is further included, a lever acting part is arranged on the lever assembly, a pushing acting part is arranged on the pushing element, and at least an upper limiting sliding area, a conversion area and a front staying area are arranged on the concentric-square-shaped groove; the sliding shaft part acts when sliding on the upper limiting sliding area and drives the pressing element and the pushing element to extend out of the rebound bracket in a sliding mode, the sliding shaft part slides to a certain position on the upper limiting sliding area and is separated fromthe pressing element, and the pushing element interacts with the lever acting part through the pushing acting part when the sliding shaft part and the pressing element are separated. Through the improvement of the structure, the practicability is high.

Description

technical field [0001] The invention relates to a labor-saving and silent push rebound opening and closing device 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, the fixed bracket is provided with a push rebound device, a telescopic reset device and at least two rotating wheels, the press rebound device at least includes a push element, and the telescopic reset device includes at least a telescopic element and a first elastic element that are elastically matched to each other. The pushing element and the telescopic element slide on the fixed bracket respectively, and at least two rotating wheels are set relatively independently and rotate on the fixed bracket respectively. When the at least two rotating wheels rotate to a ce...

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, due to the low connection compactness of the components in the push rebound mechanism, there will always be collisions between the components when opening or closing, resulting in furniture in the process of opening and closing. All kinds of abnormal noises reduce the service life of the product and affect the user experience. It is necessary to further improve
