Detailed Description

In order to make the content of the present invention more clearly understood, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the attached drawings in the embodiment of the present invention.

As shown in fig. 1-3, a pneumatic door for a granary entrance comprises a door frame 1 installed on a granary floor outlet 701, a protective guard 4 installed on the floor 7 around the outlet 401, and a chain installed on a side wall 8 of the outlet 401, wherein one end of the door frame 1 is connected with a door panel 2, the bottom surface of the door panel 2 is hinged to the inner side of the door frame 1 through a pneumatic support rod 3, a piston rod of the pneumatic support rod 3 is connected to a control cylinder 301 arranged below the floor 7, the bottom surface of the door panel 2 is provided with a handle 201, the handle 201 is fixedly installed on one side close to the protective guard 4, the top surface of the door panel 2 is fixedly connected with a handle, the handle is arranged close to the outlet 401, the handle comprises a first handle 202 and a second;

the protective guard 4 is L-shaped, one end of the protective guard 4 is arranged to be clung to the wall 8, and an outlet 401 is formed between the other end of the protective guard 4 and the wall 8;

the chain includes protection chain 5 and safety chain 6, and protection chain 5 and safety chain 6 are connected in the different positions of wall 8 through first fixed knot 501, the fixed knot 601 of second respectively, and first fixed knot 501 is close to the opening setting, and protection chain 5's tip passes through buckle swing joint in the tip that guard rail 4 is close to export 401, and export 401 setting is kept away from to the fixed knot 601 of second, and safety chain 6's the other end passes through buckle swing joint in second handle 203.
