Through the reset block 9, the second latch 61 can be pushed to rotate, so that the second latch 61 can rotate to an angle buckled with the latch hook 5.

The specific working principle of the push type damping slide rail is as follows:

when the drawer fixed on the inner rail 2 needs to be opened, at this time, the locking hook 5 on the inner rail 2 is engaged with the protrusion 441 on the first rotary piece 44, the protrusion 441 is located at the groove 71, and the second spring 43 is in a stretching state. Through pressing the drawer, effort promotes inner rail 2, and inner rail 2 passes through latch hook 5 and acts on first card post 451, drives little slider 42 through first card post 451 and removes for the arch on little slider 42 breaks away from recess 71, and the resilience force of second spring 43 stimulates little slider 42 and removes along resilient groove 4122, thereby drives first card post 451 and removes jointly, thereby first card post 451 stimulates latch hook 5 and inner rail 2 and pops out along the direction that the drawer was pulled out. With the movement of the small slider 42, the first latch 451 moves from the horizontal slot of the second sliding slot 413 to the inclined slot, and under the guiding action of the inclined slot, the second rotary piece 45 rotates and moves along the inclined slot, so that the first latch 451 is separated from the latch hook 5. Thus, the inner rail 2 and the drawer are ejected by the second spring 43, which is in a natural or compressed state.

When the drawer needs to be pulled out continuously, external force acts on the drawer, so that the inner rail 2 is pulled to move, and along with the outward movement of the inner rail 2, the locking hook 5 moves to the positioning rotary piece 6 and is buckled with the second clamping column 61. The inner rail 2 pulls the positioning rotary piece 6 to move along the third sliding groove 3121 on the extending portion 312 and gradually moves to the positioning groove 3122, and when the second latch 61 moves along the positioning groove 3122, the second latch 61 rotates around the mounting shaft 415 and gradually separates from the latch hook 5. At this time, the first spring 33 is in a stretched state, and the piston rod in the cylinder of the damper is in a pulled-out state. After the latch hook 5 is separated from the second latch post 61, the inner rail 2 can be pulled out continuously until the inner rail is pulled out to a required position, so that the use requirement is met.

When the drawer needs to be closed, external force pushes the drawer, the drawer drives the inner rail 2 to move, and when the lock hook 5 moves to the second clamping column 61, the lock hook 5 is matched with the second clamping column 61, so that the second clamping column 61 moves to the third sliding groove 3121 from the positioning groove 3122. At this moment, the big slider of resilience force pulling of first spring 33 removes, through the effect of attenuator, can prevent effectively that big slider from pulling back too fast, has prevented inner rail 2 and drawer from pulling back too fast promptly, plays the cushioning effect.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
