[0073] The fourth mounting block 78 is provided with a fifth mounting groove 780 , and the fifth mounting groove 780 is used for mounting the boosting assembly 101 .

[0074] Please continue reading Fig.12 The shift block assembly 80 includes a mounting member 81 and a shift block body 82 rotatably mounted on the mounting member 81. The mounting member 81 includes a plate body 810, a sliding pin 811 and a mounting pin 812, and the sliding pin 811 and the mounting pin 812 extend from the plate body 810. The sliding pin 811 and the mounting pin 812 are both located in the second slide groove 31102, and the shift block body 82 is rotatably mounted on the mounting pin 812. The other end of the sliding pin 811 is located in the second through hole 710 so that the mounting member 81 is rotatably mounted on the slide plate 71, and the other end of the mounting pin 812 is located in the third slide groove 711.

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

[0076] Please continue reading Figure 3 The booster 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 . The mounting plug 103 is movably installed at the end of the fifth mounting groove 780 and contacts the third elastic member 102 .

[0077] Please continue reading Figure 2 as well as Figure 3 The initial state of the slide rail is a closed state, at which time the drawer is in a closed state. When the drawer is opened, the drawer is pressed, and the external force is transmitted to the sliding rail assembly 20. The sliding rail assembly 20 drives the first paddle 22 to move a small distance in the closing direction. Since the first paddle 22 is located in the groove 45, the first paddle 22 drives the slider 40 to move in the closing direction until the locking column 53 located in the locking groove 75 slides and unlocks along the second unlocking groove 77, so that the locking piece 50 and the sliding member 70 are unlocked. At this time, the slider 40 resists the boosting assembly 101, and the elastic force of the third elastic member 102 and the pulling force of the first elastic member 60 cause the slider 40 and the locking piece 50 to move in the opening direction. The slider 40 drives the sliding rail assembly 20 to move in the opening direction through the first paddle 22, so that the drawer is ejected. The entire ejection process does not require a handle, and only requires gently pressing the drawer.

[0078] Please continue reading Fig.13 During the opening process of the slide rail, after the slide rail assembly 20 pops out, the user applies an external force to pull out the slide rail assembly 20, and the first paddle 22 drives the slider 40 to continue to move in the opening direction until the slider 40 moves to the inclined section of the slide bar 3115 and the guide column 42 moves to the inclined section of the first slide groove 31101. At this time, the slider 40 is tilted, and the first paddle 22 continues to move over the slider 40. After the first paddle 22 continues to move over the slider 40, the second paddle 23 moves to the sliding member 70, and the second paddle 23 contacts the toggle portion 821 of the paddle block body 82, so that the second paddle 23 drives the sliding member 70 to move along the slide bar 3115 until the sliding member 70 contacts the slider 40, and the locking column 53 slides along the first unlocking groove 76 into the locking groove 75 to lock. Fig.14 shown.

[0079] Please continue reading Fig.15When the user continues to apply external force to pull out the sliding rail assembly 20, since the sliding member 70 can no longer move forward, the mounting member 81 moves to the inclined section of the second slide groove 31102, and the mounting member 81 rotates relative to the sliding member 70, thereby driving the shift block body 82 to tilt, and the second shift piece 23 passes over the shifting portion 821 and continues to move forward until the sliding rail assembly 20 is completely pulled open. Fig.16 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, refer to Fig.17 , a closing thrust is applied to the drawer, and the second paddle 23 moves over the slider 40 to the sliding member 70. At this time, the second paddle 23 hits the paddle portion 821 to make the paddle block body 82 rotate in the mounting member 81, as shown in FIG. Fig.18 The second paddle 23 passes over the sliding member 70 and the paddle assembly 80 and continues to move back until the first paddle 22 moves to the slider 40 and contacts the second extension 44, so that the slider 40 moves from the inclined section of the first slide groove 31101 to the straight section. At this time, the slider 40 returns to its original position, the first paddle 22 is located in the groove 45, and the mounting member 81 moves from the inclined section of the second slide groove 31102 to the straight section, and the mounting member 81 returns to its original position. Fig.19 As shown in 20.

[0081] Subsequently, the pulling force of the second elastic member 90 causes the sliding member 70 to drive the locking plate 50, the slider 40 and the first paddle 22 to move, so that the sliding rail body 20 self-closes. During the self-closing process, the reset pin 822 of the paddle block body 82 moves to the reset groove 31103, so that the paddle block body 82 reverses and returns to its original angle, preparing for the next drawer opening, and the damping 100 reduces the closing speed to prevent hands from being pinched.

[0082] In the present application, when the sliding rail body 21 is pressed, the first paddle 22 drives the slider 40 to approach the sliding member 70 so that the locking plate 50 and the sliding member 70 are unlocked, and the first paddle 22 and the slider 40 move under the pulling force of the first elastic member 60 to make the sliding rail body 21 pop out. Therefore, when the drawer or other parts installed on the sliding rail body 21 are opened, there is no need to use a handle, and they can be automatically popped open by just gently pressing. During the closing process of the sliding rail body 21, the second paddle 23 passes over the sliding member 70 under the action of external force, and the first paddle 22 is locked with the slider 40, and the second paddle 23 is locked with the slider 40. The pulling force of the elastic member 90 causes the sliding member 70 to drive the locking piece 50, the slider 40 and the first paddle 22 to move, so that the sliding rail body 21 is self-closed. Therefore, when the drawer or other parts installed on the sliding rail body 21 are closed, the final stage of the closing is completed by the pulling force of the second elastic member 90, so as to prevent the drawer or other parts from being not completely closed. The two ends of the damper 100 are respectively connected to the mounting plate 30 and the sliding member 70. When the drawer or other parts installed on the sliding rail body 21 are closed, the damper 100 reduces the closing speed to prevent the hand from being pinched. The booster assembly 101 is installed on the sliding member 70, and the booster assembly 101 provides elastic force to the slider 40, so that the drawer can be smoothly ejected.
