[0024] The specific implementation modes of the present invention are described below to facilitate the understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0025] like Figure 1-2 As shown, the utility model provides a lightweight civil air defense door leaf, which includes a door leaf frame 1, a reinforcing assembly 2 is arranged inside the door leaf frame 1, an outer side surface of the door leaf frame 1 is arranged with an outer panel 3, and the inner side surface of the outer panel 3 is fixedly connected to the outer side surface of the door leaf frame 1 and the reinforcing assembly 2.

[0026] The reinforcement assembly 2 includes at least one reinforcement ring 21 disposed inside the door leaf frame 1, and a plurality of reinforcement ribs 22 are disposed around the reinforcement ring 21, and the ends of the plurality of reinforcement ribs 22 are fixedly connected to the inner end surface of the door leaf frame 1 or to the reinforcement ring 21. One end surface of the reinforcement ring 21 and the back surface of the reinforcement rib 22 are fixedly connected to the inner side surface of the outer panel 3.

[0027] Specifically, the plurality of reinforcing ribs 22 include a plurality of mutually interlaced transverse ribs 221 and longitudinal ribs 222; the ends of the transverse ribs 221 and longitudinal ribs 222 are fixedly connected to the inner end surface of the door leaf frame 1 or to the outer wall of the reinforcing ring 21. The plurality of reinforcing ribs 22 also include four diagonal bracing ribs 223 arranged at the four corners inside the door leaf frame 1, one end of each diagonal bracing rib 223 is fixedly connected to a corner inside the door leaf frame 1, and the other end is fixedly connected to the intersection of the transverse ribs 221 and the longitudinal ribs 222.

[0028] A reinforcing assembly 2 fixedly connected to the outer panel 3 is arranged inside the door leaf frame 1, and the reinforcing assembly 2 includes a reinforcing ring 21 and a plurality of reinforcing ribs 22. The reinforcing ring 21 and the plurality of reinforcing ribs 22 form a "M"-shaped force characteristic inside the door leaf frame 1, thereby dispersing the stress of the impact force on the door leaf of the civil air defense door, and can increase the overall strength of the door leaf of the civil air defense door, effectively increase the impact resistance of the door leaf of the civil air defense door, reduce the deformation and displacement of the door leaf of the civil air defense door, and improve the service life of the door leaf of the civil air defense door.

[0029] At the same time, the reinforcement component 2 is composed of a reinforcement ring 21 and a plurality of reinforcement ribs 22. Compared with the civil air defense door leaf that is integrally cast using a casting process, it has a light weight, requires less labor and materials, saves production materials, and reduces the production cost of the civil air defense door leaf. It not only achieves the purpose of lightweight, but also improves the impact resistance of the civil air defense door leaf.

[0030] Preferably, but not limited to, the reinforcement ring 21 is a closed circular structure, and the reinforcement ring 21 is arranged at the impact position of the outer panel 3.
