The working principle of the buffer rebound device of this application structure:

When the drawer is closed, the toggle piece 3 is buckled with the movable rail of the sliding rail and slides on the first guide rail 141 as the movable rail is closed. During this period, the elastic limiter 8 is connected to the initial upper connection level 31 of the toggle piece 3 under its elastic action, and enters the initial limit state, so that the limit block slides in the closing direction of the slide rail with the push of the toggle piece 3 , thereby driving the limiting pin 16 to slide on the directional guide groove 91 , and the rebound sliding assembly 4 slides on the second guide rail 142 .

When the restricting pin 16 slides to the top of the inclined chute 92 , the elastic restricting member 8 is compressed into the rebound sliding block 41 , so that the elastic restricting member 8 is gradually moved away from the initial upper connection level 31 . When the restricting pin 16 passes over the inclined chute 92, under the elastic action of the elastic piece 15, the restricting pin 16 is clamped on the fixed-point slot 93, and the elastic restricting member 8 and the toggle piece 3 are in a dislocation state, so that the toggle piece 3 is in the The first guide rail 141 is in a free sliding state. Since the toggle piece 3 is buckled with the movable rail, the slide rail of this structure is installed with a closing buffer 11 , so the toggle piece 3 slowly moves inward on the first guide rail under the damping action of the closing buffer 11 . During this period, under the restoring elasticity of the spring member 42, the rebound sliding assembly 4 enters the rebound initial state, and the rebound sliding assembly 4 is connected with the rebound lower connecting stage 32 of the toggle piece 3, and enters the limit state again.

When the drawer is pressed, under the action of the reset elasticity of the spring member 42, the limiting pin 16 overcomes the elastic force of the elastic sheet 15, thereby disengaging from the fixed-point clamping slot 93 and entering the orientation guide slot 91 through the inclined guide groove 94, so that the elastic limiting member 8 Push the toggle piece 3 to move outward along the first guide rail 141 , so that the drawer is unlocked and opened.
