Auxiliary mounting structure for civil air defense door

The invention provides an auxiliary mounting structure for a civil air defense door, and relates to the technical field of civil air defense engineering. The auxiliary mounting structure for the civil defense door comprises a main body, a hub assembly is fixedly connected to the bottom of the main body, load blocks are fixedly connected to the two sides of the top of the main body, a groove is formed in the middle end of the top of the main body, a moving mechanism is mounted in the groove, and an up-down adjusting mechanism is mounted at the top of the main body. A left-right adjusting mechanism is installed between the up-down adjusting mechanism and the main body, and a clamping mechanism is installed at the front end of the left-right adjusting mechanism. According to the civil air defense door mounting device, through the up-down adjusting mechanism and the left-right adjusting mechanism which are simple in design, when a civil air defense door is mounted, the civil air defense door can move up and down
