A damping buffer structure for a drawer slide rail

Abstract

A damping buffer structure of a drawer sliding rail comprises a fixed sliding rail and a movable sliding rail. A roller assembly is disposed between the fixed sliding rail and the movable sliding rail, the fixed sliding rail and the movable sliding rail are slidably opened or closed through the roller assembly, the roller assembly at least comprises a front roller and a rear roller, the front roller is arranged at the front end of the fixed sliding rail, the rear roller is disposed at the rear end of the movable sliding rail, and the fixed sliding rail and the movable sliding rail are slidably opened or closed through the front roller and the rear roller. The fixed sliding rail is provided with a damping buffer device. The damping buffer device at least comprises a fixed support assembly, a damper and a swing bolt. The damper and the swing bolt are movably arranged on the fixed support assembly, and the movable sliding rail is provided with a poking part. When the movable sliding rail is at least closed for a period of stroke relative to the fixed sliding rail, the rear roller and the poking part act on the swing bolt successively, so that the swing bolt first swings and then slides and drives the damper to be compressed to generate buffering powder, so as to perform damping buffer closing between the fixed sliding rail and the movable sliding rail. Through the structural improvement, the damping buffer structure is high in practicality.

Description

Technical field [0001] The invention relates to a damping buffer structure for drawer slide rails. Background technique [0002] Chinese patent CN2803114Y discloses an automatic opening device for drawer slide rails on August 9, 2006. The slide hooks are provided by the slide grooves of the fixing bases connected to the slide rails of the cabinet body, and the slide hooks slide by being locked to the drawer. The supporting linkage of the linkage rod of the sliding rail and the elastic restoring force of the elastic element are matched with the positioning shaft of the rocker pivoted by the fixed seat and the introduction channel, the latch channel and the outlet support channel on the back of the sliding hook The guidance of the channel and the lead-out channel is said to be able to automatically open the drawer after being pressed; in addition, when you want to open the drawer, you must press the drawer to slide it inward for more than a certain distance to achieve automatic ope...

AI Technical Summary

Problems solved by technology

However, the automatic opening device of the drawer slide rail of this structure has a complex structure, and the operation is not flexible enough in the actual use process, and a locked state will occur during its operation, and the volume is relatively large, resulting in a small position for the drawer and limited storage items. , unable to meet the needs of users
