The main working principle and process of the present utility model:

When the drawer is pulled out from the frame, the inner rail 3 that is fixedly connected to the drawer moves outward, and drives the sliding nail 52 that is fastened to the fastening mechanism of the inner rail 3. The sliding nail 52 moves to the front through the guide post 51 along the straight hole 41 , the guide post 51 moves to and is fastened to the hanging hole portion 42, and then the sliding pin 52 is disengaged from the fastening mechanism, so that the inner rail 3 can continue to move outward; while the sliding pin 52 moves to the front end, it also pushes the inner sliding The block 6 moves to the front end, and the movement of the inner slider 6 causes the first limit portion 610 of the sliding block 61 to move in the direction of the second limit portion 71 of the outer slider 7 . The limiting portion 71 becomes to push the upper outer sliding block 7 to move upward, and the top surface of the upper outer sliding block 7 bears against the sliding block 61 of the upper guide rail, thereby locking the upper guide rail, wherein the outer sliding block below the sliding block 61 7. Because of gravity, there is no need to push the sliding block 61, but the bottom surface of the sliding block 61 presses against the top surface of the lower outer slider 7, so that the lower outer slider 7 can clamp the sliding block 61 of the lower guide rail, thereby Tighten the lower rail.

When the drawer is pushed back from the frame, the inner rail 3 moves inward, and the buckle mechanism moves the sliding nail 52 along the sliding lock groove 31 in an arc shape, and the sliding nail 52 is separated from the hanging hole 42 through the guide post 51 Moving to the rear end along the straight hole 41 , the sliding nail 52 pushes the inner slider 6 to move to the rear end, and after the sliding block 61 moves to the rear end, the outer sliding block 7 above and below the sliding block 61 is free from the sliding block 61 . The abutment makes the outer sliding block 7 no longer lock the upper and lower guide rails.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , substitutions and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
