By arranging the side panels 3, the sliding door 4 overlaps with the side panels 3 when it is opened, and fits with the side panels 3 when it is closed.

[0047] like Figure 3 , Figure 4 As shown, the top and bottom of the side panel 3 are provided with clamping strips, and the top frame 1 and the bottom frame 2 are provided with corresponding clamping slots. By providing clamping strips at the top and bottom of the side panel 3, and providing corresponding clamping slots on the top frame 1 and the bottom frame 2, installation and positioning are facilitated, installation accuracy is improved, and installation difficulty is reduced. The top of the sliding door 4 is T-shaped, the bottom of the top frame 1 is provided with a corresponding T-shaped slot 15, and the top surface of the bottom frame 2 is provided with a limiting slot 21. The sliding door 4 is installed and suspended in the T-shaped slot 15 of the top frame 1, and the bottom of the sliding door 4 is installed in the limiting slot 21. The front and rear end surfaces of the bottom of the sliding door 4 are in contact with the two side surfaces of the limiting slot 21, and the bottom surface of the sliding door 4 is suspended.

[0048] like Figure 5 As shown, the buffer device 5 includes an air cylinder 51, which includes a cylinder body, a telescopic rod, and a piston. The cylinder body is a cylindrical body with an opening at one end. The cylinder body is arranged in the walls on both sides of the silent sliding door. The two ends of the cylinder body are respectively provided with front air holes and rear air holes. The piston is installed in the cylinder body. One end of the telescopic rod is connected to the piston, and the other end is extended from the opening of the cylinder body and connected to the sliding door 4. A sealing ring is arranged between the telescopic rod and the opening of the cylinder body. The front air holes and the rear air holes of the cylinder body are both provided with adjustable air pipe joints. The adjustable air pipe joint is a commonly used part for air path connection. The resistance of the action of the air cylinder 51 can be adjusted through the adjustable air pipe joint, so as to select the best sliding door speed.

[0049] like Fig.10 , Fig.11As shown, the top frame 1 is also provided with an air inlet a121, and air outlet holes 122 with upward openings are evenly provided on both sides of the T-shaped groove 15. The air inlet a121 is connected to the air outlet holes 122, and the air inlet a121 is connected to the front end air hole and the rear end air hole of the cylinder through an air pipe. A one-way valve 54 is also provided on the air pipe connecting the front end air hole and the rear end air hole of the cylinder to the air inlet a121. The top frame 1 is also provided with an air inlet b123, which is connected to the air outlet 122. The air outlet 122 connected to the air inlet a121 is located in the T-slot 15 section where the sliding door 4 is fully closed, and the air outlet 122 connected to the air inlet b123 is located in the T-slot 15 section where the sliding door 4 is fully opened; the buffer device 5 also includes a rear end air pipe 52 and a front end air pipe 53, the front end air pipe 53 connects the front end air hole of the cylinder and the air inlet b123, and the rear end air pipe 52 connects the rear end air hole of the cylinder and the air inlet a121. The air outlet 122 connected with the air inlet a121 is arranged at the T-slot 15 section where the sliding door 4 is completely closed, and the air outlet 122 connected with the air inlet b123 is arranged at the T-slot 15 section where the sliding door 4 is completely opened; the front air pipe 53 connects the front air hole of the cylinder with the air inlet b123, and the rear air pipe 52 connects the rear air hole of the cylinder with the air inlet a121. Assuming that the sliding door 4 is completely opened as the initial state, the front air hole of the cylinder is discharged when the sliding door 4 is closed, and the gas only enters from the air inlet b123 and flows out from the air outlet 122 located at the T-slot 15 section where the sliding door 4 is completely opened. In the initial state, all the air outlets 122 are located below the sliding door 4, which improves the lifting effect on the sliding door 4. Taking the sliding door 4 being completely closed as the initial state, the same effect is achieved during the process of opening the sliding door 4.

[0050] like Fig.13 , Fig.14 As shown, the bottom frame 2 is also provided with an air inlet c23 and an air blowing hole 24. The air inlet c23 is connected to the air blowing hole 24. The air inlet c23 is connected to the front air hole and / or the rear air hole of the cylinder through an air pipe. The air blowing holes 24 are evenly arranged on the side of the limiting groove 21, and the outlet direction of the air blowing holes 24 is inclined toward the center of the bottom frame 2. By setting the air blowing holes 24, the dust or sand in the bottom frame 2 can be blown to the center of the bottom frame 2 and accumulated for easy cleaning. The bottom frame 2 is also provided with a dust box 22, which is arranged below the bottom of the middle position of the limiting groove 21, as shown in FIG. Fig.15 As shown, the dust box 22 is a box body with an opening at the top, and a mounting rod 221 connecting the front and rear surfaces is provided at the opening of the dust box 22. By arranging the dust box 22 below the bottom of the middle position of the limiting groove 21, the dust particles blown in can be collected, and the dust box 22 can be conveniently disassembled and assembled by clamping the mounting rod 221, so as to facilitate the cleaning of the accumulated garbage.

[0051] like Fig. 9As shown, the top frame 1 includes a left side plate 12, a right side plate 13, and a top plate 14. The top plate 14 is arranged horizontally, and the left side plate 12 and the right side plate 13 are arranged vertically on the left and right sides below the top plate 14. By setting the top frame 1 in a form of split processing and then assembled into one body, the processing of the air inlet a121, the air outlet 122, and the air inlet b123 is facilitated. The left side plate 12, the right side plate 13, and the top plate 14 are connected as a whole by bolts or welding.

[0052] Working principle: By setting the air cylinder 51 as the buffer device 5, the faster the push and pull speed, the greater the resistance. The air cylinder 51 can limit the movement speed of the sliding door 4, alleviate the impact with the door frame, and reduce noise. By setting the sliding door 4 to be installed in the T-shaped slot 15 of the top frame 1 in a suspended manner, the bottom surface of the sliding door 4 is suspended in the air, and the T-shaped slot 15 is inverted in the air, so that no particulate garbage will accumulate, and it will not be affected by the particulate garbage during use. There will be no shaking and low noise when pushing and pulling.

[0053] By setting an air inlet a121 on the top frame 1, air outlet holes 122 with upward openings are evenly set on both sides of the inside of the T-shaped groove 15, the air inlet hole a121 is connected to the air outlet hole 122, and the air inlet hole a121 is connected to the front end air hole and the rear end air hole of the cylinder through an air pipe. A one-way valve 54 is also set on the air pipe connecting the front end air hole and the rear end air hole of the cylinder to the air inlet hole a121. Outside air can enter the air pipe through the one-way valve 54, and the air in the air pipe cannot enter the outside through the one-way valve 54 and can only be discharged through the air outlet hole 122. On the one hand, the discharged air has a lifting effect on the sliding door 4 in the T-shaped groove 15 and reduces the pushing and pulling resistance; on the other hand, it can clean up the dust and garbage in the T-shaped groove 15, thereby improving the stability of the sliding door 4 during the operation and reducing noise.

[0054] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
