Description

technical field [0001] The invention relates to the technical field of cabinet lock devices, in particular to a novel push-type rebound buffer lock. 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 lock in a cabinet lock...

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. 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
