The working principle of the buffering rebounding device with the structure is as follows:

when the drawer is closed, the pulling plate 3 is buckled with the movable rail of the slide rail and slides on the first guide rail 141 along with the closing of the movable rail. During the period, the elastic limiting part 8 is connected with the initial upper connecting level 31 of the dial piece 3 under the elastic action thereof, and enters an initial limiting state, so that the limiting block slides towards the closing direction of the slide rail along with the pushing of the dial piece 3, thereby driving the limiting pin 16 to slide in the directional guide groove 91, and the rebound sliding component 4 slides on the second guide rail 142.

When the restricting pin 16 slides to the top of the inclined slide groove 92, the elastic restricting member 8 is compressed toward the inside of the rebound slide block 41, so that the elastic restricting member 8 gradually moves away from the initial upper connecting level 31. When the limiting pin 16 goes over the inclined sliding slot 92, under the elastic action of the elastic sheet 15, the limiting pin 16 is clamped on the fixed point clamping slot 93, and the elastic limiting piece 8 and the dial piece 3 form a dislocation state, so that the dial piece 3 is in a free sliding state on the first guide rail 141. Because the shifting piece 3 and the movable rail are buckled, the closing buffer 11 is installed on the sliding rail of the structure, and the shifting piece 3 slowly moves inwards on the first guide rail under the damping action of the closing buffer 11. Meanwhile, under the elastic restoring action of the spring element 42, the rebounding sliding assembly 4 enters a rebounding initial state, and the rebounding sliding assembly 4 is connected with the rebounding lower connecting level 32 of the dial piece 3 and enters a limiting state again.

When the drawer is pressed, under the elastic action of the spring element 42, the limiting pin 16 overcomes the elastic force of the elastic sheet 15, so as to be separated from the fixed point clamping groove 93 and pass through the inclined guide groove 94 to enter the oriented guide groove 91, so that the elastic limiting element 8 pushes the shifting piece 3 to move outwards along the first guide rail 141, and the drawer is unlocked and opened. Thereupon, the drawer can be pulled to open outwards, and the paddle 3 rotates and separates from the movable rail when the first guide rail 141 is moved to the end. Meanwhile, the rebound lower connection level 32 of the dial 3 is away from the elastic limiting member 8, so that the initial upper connection level 3131 of the dial 3 passes over the elastic limiting member 8, and the elastic limiting member 8 is clamped on the initial upper connection level 31 to enter the open initial state.

Referring to fig. 1 to 13, for further refinement, the synchronous linkage assembly 7 includes a synchronous slider 71, a linkage swing rod 72, and a synchronous connecting sleeve 73.

Meanwhile, in the sliding process of the rebounding slide block 41, the pushing link 43 pushes the synchronous slide block 71 of the synchronous linkage assembly 7, so that the synchronous slide block 71 moves forward on the rebounding base plate 14 and drives the swing linkage swing rod 72 to swing forward, and the synchronous link 6 is linked to rotate, so that the left rebounding component 1 and the right rebounding component 2 on the left side and the right side of the drawer synchronously move.

During the closing of the slide, the drive positioning pin 51 passes over the drive orientation slot 101 and enters the drive positioning slot 102, and when the left and right rebound members 1 and 2 respectively enter the rebound limit state under the elastic action of the spring member 42, the drive positioning pin 51 is connected with the synchronization slider 71 while the drive guide slot slides back.

At this time, the synchronization slider 71 is pushed down to the rebound slider 41, and the transmission positioning pin 51 and the synchronization slider 71 are displaced and separated, so that the synchronization link assembly 7 enters the open state, and interference between the components is reduced. Subsequently, the rebound slider 41 and the transmission link slide to the open original state.
