Pressing type rebound cushioning lock with short triggering distance

Abstract

The invention discloses a pressing type rebound cushioning lock with short triggering distance, including a drive assembly disposed within the shell, a transmission assembly and a linkage assembly, wherein the linkage assembly further comprises a linkage part sliding reciprocally along a linkage sliding groove preset on the shell and a movable clip sliding reciprocally along a clip sliding groovepreset on the shell, wherein two ends of the clip sliding groove extend to the avoidance groove and the linkage sliding groove respectively; at both end of the movable card part, an unlocking end which is in conflict with the transmission stop block and a stopping end which is in conflict with the linkage part are respectively for, as the stop end withdraw or slides into the linkage slide groove,the unlocking end blocks or avoids the transmission stop from withdrawing from the avoidance groove, thereby realizing the unlocking function of the transmission stopper in a short distance by light pressing, and achieving the effects of short distance triggering and high sensitivity.

Description

technical field [0001] The invention relates to the technical field of a drawer buffer, in particular to a push-type rebound buffer lock with a short trigger distance. Background technique [0002] Existing bounce-back drawers often use a drawer bouncer to realize the opening and closing of the drawer by touching the drawer. However, the quality of the existing drawer bouncers varies. After a period of use, it is easy to get stuck or cannot be closed by pressing. Affect the use of the drawer; there are various working methods for the drawer guide rails on the market. Some guide rails can buffer and self-close when the drawer is closed, but they need to be pulled out manually; some guide rails can realize the rebound function, and the drawer can be pressed automatically. It pops up, but there is no cushioning effect when the drawer is closed, and it is prone to drawer slamming sound. [0003] The Chinese patent 2017202328541 applied by the applicant discloses a push-type loc...

Pops up, but no cushioning effect when the drawer is closed, prone to drawer slamming sound

[0003] The Chinese patent 2017202328541 applied by the applicant discloses a push-type lock in a cabinet lock device with a push-type rebound lock, which enables the drawer to be closed by adding a rebound lock on the basis of the buffer guide rail. While having a cushioning effect, the drawer can automatically pop up after being pressed; however, when the lock is pressed and popped up, there will be a collision sound due to the collision between the transmission block and the rebound push block on the drive push block. In the drawers with high quiet requirements, the requirements are often not met
