[0023] like Figure 1-Figure 4 As shown;

[0024] A chain-type pneumatic lifting door assembly comprises a main rod 1 and an upper door panel 2 installed on one side adjacent to two main rods 1 .

[0025] In this embodiment: after checking the public (announcement) number: CN206858053U discloses a chain-type pneumatic lifting device, which discloses "a chain-type pneumatic lifting device, including a fixed frame, a lifting railing and a lifting power device; a sprocket wheel 1, a sprocket wheel 2 and a connecting screw rod 3 are installed on the fixed frame; a sprocket wheel 3 is installed on the lifting power device; a main chain is meshed with the sprocket wheel 1, the sprocket wheel 2 and the sprocket wheel 3, one end of the main chain is connected to the screw rod 3, and the other end of the main chain is connected to the lifting railing through a left chain and a right chain respectively The invention discloses a chain-type pneumatic lifting device, which can be connected by meshing of chains on different sprockets, with the end of the main chain connected to a chain fixing block, and two chains are separated from the lower part of the chain fixing block to fix one side of the lifting railing respectively, and the lifting railing is guided by a guide wheel, and the lifting railing is smoothly lowered and raised by the extension and contraction of the cylinder piston rod. The whole lifting device works stably and reliably, is economical and practical, and is easy to install and maintain.

[0026] When the existing lifting door assembly is in use, the lifting door is relatively large and cannot be stored in a limited space. In addition, when it is directly pushed by a servo motor or a cylinder, a large reaction force will be generated, which may easily damage the motor and the cylinder. Multiple lifting doors cannot be opened progressively in a limited space. In terms of actual use, this problem is obviously a real problem that is difficult to solve. In view of this, an embodiment of the present invention is to solve this technical problem.

[0027] An L-shaped side plate 3 is installed on the outer surface of the main rod 1, and a pneumatic push rod 4 is installed on one side surface of the side plate 3. A U-shaped bracket 5 is installed on the protruding end of the pneumatic push rod 4. A sprocket 7 is rotatably connected inside the bracket 5. A chain 6 is meshingly connected to the outer surface of the sprocket 7. An L-shaped ear plate 14 is installed on one end of the chain 6. The ear plate 14 is installed on the outer surface of the main rod 1 by bolts. A pull rod 8 is installed on the other end of the chain 6. A bracket 9 is hinged at one end of the pull rod 8. The same lower door panel 10 is installed on one side surface of the two brackets 9. The top surface of the lower door panel 10 is abutted against two top panels 12. The two top panels 12 are installed with a middle door panel 11 by bolts.

[0028] The pneumatic push rod 4 on the side plate 3 pushes the bracket 5 to move up, and at the same time, the bracket 5 can drive the sprocket 7 to push the chain 6, one end of the chain 6 is installed on the ear plate 14 outside the main rod 1, and the pneumatic push rod 4 pushes the chain 6 to pull the lower door plate 10 on the bracket 9 through the pull rod 8, so that the lower door plate 10 moves up. After moving to the position aligned with the middle door, it will support the top plate 12 on the middle door plate 11, and then continue to move up, which will drive the middle door plate 11 to break away from the block 13, and the middle door plate 11 and the lower door plate 10 are guided and limited by the guide rods on the side plate 3 to prevent the middle door plate 11 and the lower door plate 10 from shaking when moving, and continue to move up to the position aligned with the upper door plate 2, so that the middle door plate 11 and the upper door plate 2 can be pushed in turn to control their opening and closing, and control the range of opening.

[0029] In an optional embodiment: rollers 15 are rotatably connected to both sides of the middle door panel 11 and the lower door panel 10 , and the outer surfaces of the rollers 15 are rotatably connected to two U-shaped guide plates 16 , which are installed on one side surface of the side panel 3 .

[0030] In this embodiment, the roller 15 can slide in the guide plate 16 of the U-shaped structure, thereby improving the stability of the upper door panel 2 and the lower door panel 10 when moving, and avoiding the upper door panel 2 and the lower door panel 10 from shaking.

[0031] In an optional embodiment, the bracket 9 is arranged in an L shape, and the bracket 9 is slidably connected to a side surface of the side plate 3 .

[0032] In this embodiment, the upper door panel 2 and the lower door panel 10 can be connected by a bracket 9 of an L-shaped structure.

[0033] In an optional embodiment, the middle door panel 11 and the lower door panel 10 are of the same size.

[0034] In this embodiment, after the lower door panel 10 moves to a position aligned with the middle door panel 11 , the top panel 12 will continue to push the middle door panel 11 upward.

[0035] In an optional embodiment, a stopper 13 made of rubber material is installed in the guide plate 16 on the side close to the upper door panel 2 by means of bolts.

[0036] In this embodiment, the stopper 13 in the guide plate 16 can abut against the middle door plate 11 to control the moving range of the middle door plate 11 so that the middle door plate 11 automatically stops after moving to the position.

[0037] The working principle and use process of the utility model are as follows: the pneumatic push rod 4 on the side plate 3 pushes the bracket 5 to move up, and at the same time, the bracket 5 can also drive the sprocket 7 to push the chain 6. One end of the chain 6 is installed on the ear plate 14 outside the main rod 1. The pneumatic push rod 4 pushes the chain 6 to pull the lower door plate 10 on the bracket 9 through the pull rod 8, so that the lower door plate 10 moves up. After moving to the position aligned with the middle door, it will support the top plate 12 on the middle door plate 11, and then continue to move up, which will drive the middle door plate 11 to break away from the block 13. The middle door plate 11 and the lower door plate 10 are guided and limited by the guide rods on the side plate 3 to prevent the middle door plate 11 and the lower door plate 10 from shaking when moving, and continue to move up to a position aligned with the upper door plate 2, so that the middle door plate 11 and the upper door plate 2 can be pushed in turn to control their opening and closing, and control the range of opening.
