[0002] With the improvement of environmental protection and energy saving requirements, the powder spraying process is gradually replacing the paint spraying process, so that the drying temperature is about 200-220 DEG C. In order to prevent the loss of heat when the equipment door is opened and cause the waste of energy, it is required that in addition to the large door set at the entrance and exit of the drying chamber, a large door is also set at the partition of the drying chamber. The two large doors are opened in turn, thereby reducing the heat loss of the opening type large door.

[0003] At present, the large door of the partition is driven by a cylinder arranged on the opposite opening door. The cylinder is respectively installed on the two sides of the equipment door support and connected with the door plate. One cylinder is matched with one door plate. Compressed air is used as the power source. The opening and closing of the single door are controlled by the extension and retraction of the cylinder.

[0004] Since one cylinder drives one door plate, the following problems exist. The two cylinders are inevitably out of synchronization when opening and closing. In addition, the cylinder, pneumatic components, compressed air pipe and electromagnetic reversing valve cannot withstand high temperature, so they cannot meet the requirements of synchronization and high temperature working conditions.

[0013] The driving cylinder is installed outside the wall body through the third connecting rod, and the wall body is used for isolation, so that the high temperature does not affect the driving cylinder.

[0014] Further, a triangular plate is further included, one corner of the triangular plate is positioned and rotatably arranged, and the other two corners of the triangular plate are respectively hingedly connected with the output end of the driving cylinder and the end of the third connecting rod away from the connecting rod assembly.
