Nuts are threaded at both ends of the post.

[0008] Furthermore, the base has mounting grooves on its top, which are symmetrically distributed, and the positioning frame has mounting holes, which are symmetrically distributed.

[0009] Furthermore, both the limiting frame and the positioning frame are arranged in a geometric shape, and the guide rail is arranged in a long strip shape.

[0010] The beneficial effects of this utility model after adopting the above structure are as follows:

[0011] (1) The column can be restricted between the limiting frame and the upright plate and fixed with bolts, which ensures the connection stability between the square tube and the base;

[0012] (2) The stability of the connection between the square tube and the wall can be increased by setting the installation components;

[0013] (3) The brackets can be quickly connected to the square tubes so that the decorative panels can be connected to the brackets, which improves the convenience of installing the air defense door accessories. Attached Figure Description

[0022] like Figure 1-3As shown, the detachable air defense door accessory includes a base 1 and a square tube 2. The square tube 2 is installed on the top of the base 1. A limit frame 3 is fixedly connected to the top of the base 1. Symmetrically distributed upright plates 4 are fixedly connected to the top of the base 1. Symmetrically distributed side plates 5 are fixedly connected to the outer side wall of the square tube 2. The side plates 5 are installed between the limit frame 3 and the upright plates 4 by bolts. It also includes an installation component and a connecting component. The installation component is located on the square tube 2, and the connecting component is located on the square tube 2. The connecting components are arranged vertically on the square tube 2.

[0023] like Figure 1-6 As shown, in order to stably connect the square tube 2 to the wall, the installation components include a positioning frame 6, a insert plate 7, and a positioning rod 8. The positioning frame 6 is snapped onto the outer wall of the square tube 2. The top of the positioning frame 6 has a notch 9. The insert plate 7 is inserted into the notch 9. The positioning rod 8 passes through the positioning frame 6 and the square tube 2 and is threadedly connected to them. One end of the positioning rod 8 passes through the insert plate 7 and is threadedly connected to the insert plate 7. One end of the positioning rod 8 is threadedly connected to a locking element 10.

[0024] like Figure 1-6 As shown, in order to facilitate the connection between the decorative panel and the square tube 2, the connection assembly includes a hanger 11, a guide rail 12, and a post 13. The guide rail 12 is fixedly connected to the outer wall of the square tube 2 and is symmetrically distributed in pairs. The hanger 11 is slidably mounted on the guide rail 12 and is clipped onto the outer wall of the square tube 2. The post 13 passes through the hanger 11 and the square tube 2 and is threadedly connected to them. Nuts 14 are threadedly connected to both ends of the post 13.
