Description

Technical Field

[0001] This utility model relates to the field of civil defense door technology, and in particular to a civil defense door with impact resistance and an assisted opening mechanism. Background Technology

[0002] Civil defense doors are an important component of civil defense projects. In emergencies such as war and natural disasters, they play a crucial role in protecting the safety of personnel and materials. They can not only withstand the impact of blast waves and shrapnel, but also provide waterproof, fireproof, and toxic gas protection, providing people with a relatively safe refuge space.

[0003] Existing air-raid shelter doors have the following drawbacks:

[0004] 1. Early civil defense doors mostly used simple steel or reinforced concrete structures. When subjected to high-intensity impacts, the doors were prone to deformation, cracking, or even breakage, which could not effectively guarantee the safety of the interior of civil defense projects.

[0005] 2. Civil defense doors are usually heavy and have complex opening structures. In particular, the doors at the entrances and exits of some large civil defense projects require a lot of physical strength and time to open in the event of an emergency evacuation, which may affect the evacuation and rescue work. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an impact-resistant air defense door with an assisted opening mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The adjustable opening mechanism includes a connecting groove, a first connecting bushing, a connecting pin, a second connecting bushing, a door body, a limiting groove, a positioning rod, a first rotating disk, a connecting shaft, a second rotating disk, a fixing plate, an electric telescopic rod, and a mounting plate. The first connecting bushing is sleeved with the second connecting bushing through the connecting pin. The outer walls of one end of the door body are tightly connected to the surface of one side of the two second connecting bushings, respectively. One end of the positioning rod is engaged in the interior of the limiting groove, and the other end of the positioning rod is fixedly connected to the side of the first rotating disk. The rotating disk is sleeved on one end of the connecting shaft, and one end of the connecting shaft is fixedly connected to the second rotating disk. The top of the electric telescopic rod is welded to the bottom outer wall of the positioning rod through the fixing plate, and the bottoms of the two electric telescopic rods are respectively embedded in the two ends of the surface of the mounting plate.

[0011] Preferably, the protective mechanism includes a base plate, rubber round pads, reinforcing rods, U-shaped reinforcing frames, rubber shock-absorbing plates, and spring buffer assemblies. Multiple rubber round pads are respectively fixedly connected to both ends of one side surface of the base plate, the two ends of multiple reinforcing rods are respectively fixedly connected to the four corners of the base plate, multiple U-shaped reinforcing frames are movably connected to the surface of the base plate, and the rubber shock-absorbing plates are tightly connected to the outer wall of the base plate.

[0012] The above solutions, including the installation of protective mechanisms, base plates, rubber pads, reinforcing rods, U-shaped reinforcing frames, rubber shock-absorbing plates, and spring buffer assemblies, can add a fixed structure to traditional air-raid shelter doors, thereby improving the door's pressure resistance to a certain extent.

[0013] Preferably, the spring buffer assembly includes a helical spring, a fixed connector, a telescopic rod, and buffer plates. The helical spring is connected to the telescopic rod via the fixed connector, and the two buffer plates are fixedly connected to both ends of the helical spring.

[0014] Preferably, the door frame is provided with a connecting groove, and the inner walls on both sides of the door frame are provided with limiting grooves, and one side surface of the mounting plate is in close contact with the bottom outer wall of one side of the door body.

[0015] Preferably, the outer walls on both sides of the substrate are fitted inside the door body, and the two spring buffer assemblies are respectively fixedly connected to the surface of the rubber shock-absorbing plate.

[0016] Preferably, one end of the outer wall of each of the two first connecting bushings is welded to both ends of one side surface of the door frame.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By installing an adjustable opening mechanism, the interconnected structure of the connecting groove, first connecting bushing, connecting pin, second connecting bushing, door body, limit groove, positioning rod, first rotating disc, connecting shaft, second rotating disc, fixing plate, electric telescopic rod and mounting plate can be quickly opened in the event of an emergency evacuation, thereby reducing the consumption of physical strength and time, and providing certain convenience for personnel evacuation and rescue work.

[0019] 2. By installing protective mechanisms, the various components such as the base plate, rubber round pad, reinforcing rod, U-shaped reinforcing frame, rubber shock-absorbing plate, and spring buffer assembly can add a fixed structure to the traditional air defense door, thereby improving the door's pressure resistance to a certain extent.
