[0075] The dial block body 82 includes a dial portion 821 and a reset pin 822. The dial portion 821 is in contact with the second dial piece 23, so that the second dial piece 23 drives the sliding piece 70 to move. The reset pin 822 is located in the second sliding groove 31102. When the second sliding groove 31102 moves to the reset groove 31103, the reset groove 31103 drives the dial block body 82 to reverse reset through the reset pin 822.

[0076] Please continue to refer to Figure 3 , the boost assembly 101 includes a third elastic member 102 and a mounting plug 103. The third elastic member 102 is installed in the fifth mounting groove 780, and the mounting plug 103 is movably installed at the end of the fifth mounting groove 780 and in contact with the third elastic member 102.

[0077] Please continue to refer to Figure 2 and Figure 3 , the slide rail is in a closed state initially, and at this time, the drawer is in a closed state. When the drawer is opened, an external force is transmitted to the slide rail assembly 20, and the slide rail assembly 20 drives the first dial piece 22 to move a small distance in the closing direction. Since the first dial piece 22 is located in the groove 45, the first dial piece 22 drives the sliding block 40 to move in the closing direction until the locking column 53 in the locking groove 75 slides along the second unlocking groove 77 to be unlocked, so that the locking piece 50 is unlocked with the sliding piece 70. At this time, the sliding block 40 is in contact with the boost assembly 101, and the elastic force of the third elastic member 102 and the pulling force of the first elastic member 60 drive the sliding block 40 and the locking piece 50 to move in the opening direction. The sliding block 40 drives the slide rail assembly 20 to move in the opening direction through the first dial piece 22, so as to realize the drawer pop-out. The entire pop-out process does not need a handle, and only needs to press the drawer gently.

[0078] Please continue to refer to Figure 13 , during the opening process of the slide rail, after the slide rail assembly 20 is popped out, the user applies an external force to pull out the slide rail assembly 20. The first dial piece 22 drives the sliding block 40 to continue to move in the opening direction until the sliding block 40 moves to the inclined section of the sliding bar 3115 and the guide column 42 moves to the inclined section of the first sliding groove 31101. At this time, the sliding block 40 is inclined, and the first dial piece 22 continues to move beyond the sliding block 40. When the first dial piece 22 continues to move beyond the sliding block 40, the second dial piece 23 moves to the sliding piece 70, and the second dial piece 23 is in contact with the dial portion 821 of the dial block body 82, so that the second dial piece 23 drives the sliding piece 70 to move along the sliding bar 3115 until the sliding piece 70 is in contact with the sliding block 40. The locking column 53 slides along the first unlocking groove 76 into the locking groove 75 to be locked, as shown in Figure 14 .

[0079] Please continue to refer to Figure 15When the user continues to apply pulling force to the sliding rail assembly 20, since the slider 70 can no longer move forward, the mounting member 81 moves to the inclined section of the second slide groove 31102. The mounting member 81 rotates relative to the slider 70, thereby causing the lever body 82 to tilt. The second lever 23 passes over the lever part 821 and continues to move forward until the sliding rail assembly 20 is fully pulled open. Figure 16 As shown. At this time, the first sliding rail 210, the second sliding rail 211, and the fixed rail 10 are in a straight line.

[0080] When you need to close the drawer, please refer to Figure 17 Applying a closing force to the drawer, the second lever 23 moves past the slider 40 to the slider 70. At this time, the second lever 23 strikes the actuating part 821, causing the lever body 82 to rotate within the mounting part 81. Figure 18 As shown. The second lever 23 moves backward past the slider 70 and the lever assembly 80 until the first lever 22 moves to the point where the slider 40 abuts against the second extension 44, causing the slider 40 to move from the inclined section of the first groove 31101 to the straight section. At this time, the slider 40 returns to its original position, and the first lever 22 is located in the groove 45. Simultaneously, the mounting member 81 moves from the inclined section of the second groove 31102 to the straight section, and the mounting member 81 returns to its original position, as shown. Figure 19 And as shown in 20.

[0081] The subsequent pulling force of the second elastic element 90 causes the sliding element 70 to move the locking piece 50, the slider 40 and the first lever 22, causing the sliding rail body 20 to self-close. During the self-closing process, the reset pin 822 of the lever body 82 moves to the reset groove 31103, causing the lever body 82 to reverse and return to its original angle, preparing for the next drawer to open. The damper 100 reduces the closing speed to prevent pinching.

[0082] When the slide rail body 21 is pressed in the application, the first tab 22 drives the slider 40 to approach the slide 70 to unlock the slide 70 and the slide 70, the first tab 22 and the slider 40 are moved under the tension of the first elastic element 60 to make the slide rail body 21 pop out, so when the drawer or other parts installed on the slide rail body 21 are opened, no handle is needed, only a slight press is needed, and the drawer or other parts can be automatically popped open; during the closing process of the slide rail body 21, the second tab 23 passes the slide 70 under the action of external force, the first tab 22 is buckled with the slider 40, the tension of the second elastic element 90 makes the slide 70 drive the lock piece 50, the slider 40 and the first tab 22 to move, so that the slide rail body 21 is self-closed, so when the drawer or other parts installed on the slide rail body 21 are closed, the last segment of the closing is completed by the tension of the second elastic element 90, preventing the existence of the drawer or other parts without completely closing; the damper 100 is connected with the mounting plate 30 and the slide 70 at both ends, when the drawer or other parts installed on the slide rail body 21 are closed, the damper 100 reduces the closing speed to prevent hand clamping. The booster assembly 101 is installed on the slide 70, the booster assembly 101 provides elastic force to the slider 40 to make the drawer pop out smoothly.
