Silent pressing rebound opening and closing structure

Abstract

The invention discloses a silent pressing rebound opening and closing structure. The silent pressing rebound opening and closing structure comprises a rebound support, a pushing element and a slidingelement, wherein a heart-shaped sliding groove is formed in the rebound support; the pushing element is provided with a sliding part and is positioned and / or slides along a track of the heart-shaped sliding groove in a sequential direction through the sliding part; the sliding element is provided with a heart-shaped groove slide-in guide part and a movable part; the movable part is elastically movable on the sliding element and is provided with a heart-shaped groove slide-in buffer part; when the sliding element slides into the rebound support, the heart-shaped groove slide-in guide part actsand the sliding part is driven to slide along the track of the heart-shaped sliding groove in the sequential direction; and when sliding to a certain position, the sliding part interacts with the heart-shaped groove slide-in buffer part, the movable part is elastically movable on the sliding element under the action of the sliding part, and the sliding part is guided to slide into and stay in theheart-shaped sliding groove through the heart-shaped groove slide-in buffer part in the moving process. Through the improvement of the structure, the practicability is high.

Description

technical field [0001] The invention relates to a silent pressing rebound opening and closing 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 ...

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. Since the third elastic element has a large elasticity, 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
