[0029] In order to make the content of the present utility model easier to be clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0030] As Figure 1 shown, the technical solution of the present utility model is: a civil air defense door with a safety support device, including that the front side of the door frame 1 is connected to the civil air defense door panel 2, and it is convenient to install the civil air defense door panel 2 through the door frame 1. There are two civil air defense door panels 2, and hinges are connected between the civil air defense door panel 2 and the door frame 1. The baffle 3 is fixedly connected to the rear side of the upper end face inside the door frame 1, and the civil air defense door panel 2 is limited by the baffle 3.

[0031] As Figure 2 and Figure 4As shown, there are two support devices 4, and the support devices 4 are respectively connected to the baffle 3 and the civil air defense door panel 2. The support device 4 includes: a first hinge seat 401, the first hinge seat 401 is fixedly connected to the front end face of the baffle 3, one end of a first connecting rod 402 is rotatably connected in the first hinge seat 401, the other end of the first connecting rod 402 is fixedly connected to a second hinge seat 403, a first threaded rotating plate 404 is provided at the front end of the second hinge seat 403, one end of the first threaded rotating plate 404 is a convex block and the other end is a lead screw, one end of the lead screw of the first threaded rotating plate 404 is threadedly connected to an adjusting column 405, the other end of the adjusting column 405 away from the first threaded rotating plate 404 is threadedly connected to a second threaded rotating plate 406, one end of the second threaded rotating plate 406 away from the adjusting column 405 is rotatably connected to a third hinge seat 407, one end of a second connecting rod 408 is fixedly connected to the third hinge seat 407 away from the second threaded rotating plate 406, the other end of the second connecting rod 408 is rotatably connected to a fourth hinge seat 409, and the fourth hinge seat 409 is fixedly connected to the upper end face of the civil air defense door panel 2. When the civil air defense door panel 2 is opened, the support device 4 is straightened into a straight line. When the adjusting column 405 is rotated, the distance between the first connecting rod 402 and the second connecting rod 408 can be adjusted. Through the hinges between the various components, the civil air defense door panel 2 can be controlled to open to the limit position. When the civil air defense door panel 2 is closed, the support device 4 is folded in a Z shape to prevent the support device 4 from occupying extra space. Concave grooves 5 are opened at the lower part of the outer end face of the civil air defense door panel 2, and fixing components 6 are provided in the concave grooves 5. It is convenient to place the fixing components 6 through the concave grooves 5.

[0032] As Figure 2 , Figure 3 and Figure 4 shown, the fixing component 6 includes a rotating block 601 slidably connected in the concave groove 5.
