First trigger piece 2 is used for the trigger of opening door, and second trigger piece 3 is used for the trigger of closing door. Two -way buffer body 1 is equipped with the hanging wheel subassembly 4 respectively at both ends, and the hanging wheel subassembly 4 lower end is connected with the installation box 5 through the screw rod. The hanging wheel subassembly 4 of usually one side with two -way buffer body 1 is fixed connection, and the hanging wheel subassembly 4 of the other side with two -way buffer body 1 is split body connection. Wherein the installation box 5 on fixed connection side is connected with press rebound mechanism 6. Press rebound mechanism 6 includes shell 7, movable support 8, tension spring 9, energy storage buckle 10, energy release rod 11, first baffle 12, second baffle 13 and third baffle 14. The first linear sliding slot 15 and the variable direction arc sliding slot 16 that the first linear sliding slot 15 end is smooth transition are equipped with in the shell 7 inner chamber front end, and one side of shell 7 is equipped with opening 17. For the convenience of assembly, shell 7 is composed of upper shell and lower shell. For improving the strength, metal sheath 701 is also usually equipped outside shell 7. Movable support 8 can be slidably installed in shell 7, and the first trigger part 18 of movable support 8 front end is equipped with the first trigger part 18 of movable support 8 front end and is located the first trigger part 18 rear. The other end of tension spring 9 is connected to the rear end of movable support 8. The front end of energy storage buckle 10 is rotatably connected to the front end of movable support 8 through pivot 19, and is located the first trigger part 18 rear. Energy storage buckle 10 is equipped with U-shaped groove 20 that is adapted to movable support 8 and front guide shaft 21 and rear guide shaft 22 that cooperate with first linear sliding slot 15 and variable direction arc sliding slot 16 and second trigger part 23 that extend out of opening 17. By the accommodation of U-shaped groove 20, energy storage buckle 10 can rotate at a large angle on movable support 8. Energy release rod 11 is movably arranged in shell 7, and the front end of energy release rod 11 is provided with energy release button 25 that extends from the front end of shell 7, and the rear end of energy release rod 11 is provided with push part 26 that is used for pushing energy storage buckle 10 away from variable direction arc sliding slot 16, and reset spring 24 is arranged between energy release button 25 and shell 7 for resetting after pressing energy release button 25. First baffle 12, second baffle 13 and third baffle 14 are all installed in sliding door track, and are matched with second trigger part 23, first trigger part 18 and energy release button 25 respectively.

[0029] Preferably, the second trigger part 23 is higher than the first trigger part 18. The first baffle plate 12 is used to block the second trigger part 23, and the second baffle plate 13 is used to block the first trigger part 18. When assembled: the second baffle plate 13 should be on the inside, and the first baffle plate 12 on the outside. A torsion spring 27 is arranged on the rotating shaft 19, which is used to drive the energy storage buckle 10 to rotate inward. The rear end of the first straight sliding slot 15 is provided with a let gap 28, when the second trigger part 23 approaches the first baffle plate 12, the rear guide shaft 22 enters the let gap 28, so that the energy storage buckle 10 can be pressed to compress at this position. When the door is almost completely opened (the door body is almost embedded in the wall), the lower first trigger part 18 can normally pass through the first baffle plate 12, and the second trigger part 23 is blocked by the first baffle plate 12, thereby driving the sliding of the energy storage buckle 10 and the movable support 8, and further driving the stretching of the tension spring 9. When the energy storage buckle 10 slides to the position of the turning arc-shaped sliding slot 16, it will change direction because the rear guide shaft 22 enters the turning arc-shaped sliding slot 16, so that the second trigger part 23 enters the shell 7 (see Figure 7 ), at this time, the second trigger part 23 is separated from the first baffle plate 12, to complete the energy storage process of the tension spring 9. Usually after completing the energy storage, the sliding door continues to slide for a short distance to open to the position, at this time, continuing to push the sliding door will trigger the collision of the energy release button 25 and the third baffle plate 14, thereby making the energy release rod 11 push the energy storage buckle 10 away from the turning arc-shaped sliding slot 16, and then the tension spring 9 can pull the movable support 8 and the energy storage buckle 10 to reset, because the second baffle plate 13 blocks the first trigger part 18, thereby driving the pop-up of the sliding door. During the pop-up process, in order to prevent interference between the second trigger part 23 and the first baffle plate 12, when the second trigger part 23 approaches the first baffle plate 12, the rear guide shaft 22 enters the let gap 28, so that the energy storage buckle 10 can be pressed to compress at this position, thereby normally passing through the first baffle plate 12. When the energy storage buckle 10 leaves the first baffle plate 12, it can automatically reset under the action of the torsion spring 27.

[0030] Preferably, after the first baffle plate 12 hits the second trigger part 23 to make the rear guide shaft 22 enter the turning arc-shaped sliding slot 16, the first trigger part 2 synchronously triggers the two-way buffer body 1 to buffer, to realize the synchronous completion of energy storage and buffering.

[0031] Preferably, the distance between the front guide shaft 21 and the rear guide shaft 22 is greater than the width of the let gap 28. So that before the rear guide shaft 22 enters the let gap 28, the front guide shaft 21 has left the let gap 28, to ensure the stability of the sliding and rotating of the energy storage buckle 10.

[0032] Preferably, the end faces of both the first trigger part 18 and the second trigger part 23 are provided with rubber pads 29 to cushion impacts and reduce noise.

[0033] Preferably, the first baffle 12 and the second baffle 13 are integrally formed, and a first positioning rod 30 is provided at the rear end. The third baffle 14 is provided with a second positioning rod 31 at the rear end. Because this structure requires very high precision in the installation position of the first baffle 12, the second baffle 13, and the third baffle 14, the first positioning rod 30 and the second positioning rod 31 are used to achieve precise installation. During installation: simply align the ends of the first positioning rod 30 and the second positioning rod 31 with the edge of the door frame.

[0034] Preferably, a reinforcing ring 32 is fitted on the rear guide shaft 22 to improve the strength and wear resistance of the rear guide shaft 22.

[0035] Preferably, the rear ends of the inner cavity of the housing 7 are provided with second linear grooves 33, and the movable bracket 8 is provided with a first guide rail 34 that guides and cooperates with the second linear grooves 33, so as to improve the sliding stability of the movable bracket 8.

[0036] Preferably, the first trigger part 18 is provided with a second guide rail 35 that cooperates with the first linear slide groove 15 to improve the sliding stability of the first trigger part 18. The bottom ends of the housing 7 are provided with third guide rails 36, which cooperate with the door frame guide rail groove to improve the stability of the housing 7 after installation. Example 2:

[0037] like Figure 8 As shown, the embedded sliding door of this utility model includes a sliding door track 37 and a sliding door 38 disposed below the sliding door track 37.
