Buffer rebound locking device

Abstract

A buffer rebound locking device comprises a fixed block and a movable block which are connected in a sliding mode; a frame body is arranged on the fixed block, the buffer rebound locking device further comprises a buffer sliding block, a rebound sliding block, a hanging pin, a hanging nail, a first elastic piece and a second elastic piece, and a first sliding groove and a second sliding groove are formed in the frame body; the hanging pin is provided with a first shaft body and a second shaft body, a third shaft body and a fourth shaft body are arranged on the hanging nail; a locking position and a first receding position are arranged at the tail end of the second sliding groove, a second receding position is arranged at the starting end of the second sliding groove, and a pushing block and a buffering hook are arranged on the movable block. According to the buffering rebound locking device, the movable block is pressed after the fixed block and the movable block are buffered and closed, automatic popup of the movable block can be achieved, so that when the buffering rebound locking device is applied to a drawer, the drawer is pressed again after being closed and can automatically pop up, a handle does not need to be arranged on the drawer, so that the drawer has better appearance and the buffering rebound locking device is simple in structure and convenient to use. The device only uses a small number of parts, so that the machining process can be simplified, more cost is saved, and the performance is stable.

Description

technical field

[0001] The invention particularly relates to a buffer rebound locking device. Background technique

[0002] The outside of the traditional drawer is generally provided with a handle, and the drawer is pulled out through the handle, but the handle will affect the appearance of the drawer. To solve this problem, Chinese Patent Document No. CN211961454U disclosed on November 20, 2020 a self-rebounding method by pressing. Lock buffer device, including rebound self-locking main frame, self-locking slider, rebound slider, rebound reset start mechanism, self-locking start shift fork, rebound swing hook, self-locking hook, rebound self-locking toggle lever, self-locking spring , rebound spring and automatic extension cylinder. When the drawer is in the closed state, the user gently presses the drawer panel with his hand, and the drawer will move slightly forward about 33.5mm at this time, because the rebound reset activation mechanism fixed in the rebound self-locki...
