[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. They are civil defense protection equipment. Their main function is to provide a certain degree of protection and sealing functions to protect people's lives and property during natural disasters such as wars or earthquakes. Civil defense doors are usually made of two types: concrete and steel. Their sizes vary according to actual needs. They are designed according to five and six standards and are divided into two parts: door frame and door leaf. The door frame is an one-piece angle steel, and the door leaf is made of steel mesh and concrete. At present, civil defense doors are mostly used for entrances and exits of laboratories, hospitals, warehouses, underground parking lots, etc.

[0025] For example, please refer to Figure 1 , Figure 2 and Figure 3 The door frame 1 and the door panel 3 are both made of lead plates and are covered with stainless steel materials on the outside to achieve radiation resistance.

[0026] The magnetic plate 4 on the frame edge 2 and the magnet 5 on the door panel 3 are matched electric magnetic door components, and the magnet 5 just fits with the magnetic plate 4 when the door panel 3 is closed. The magnetic plate 4 and the magnet 5 are connected in parallel to a controller, and the electric attraction between the magnetic plate 4 and the magnet 5 is realized by the controller. When the door panel 3 is closed, the magnetic plate 4 and the magnet 5 fit together. At this time, the controller energizes the magnetic plate 4, so that the magnetic plate 4 and the magnet 5 are tightly attracted together, and at the same time cooperates with the hand wheel door lock 6 to lock the door panel 3, so that the entire door panel 3 is more stable and reliable after closing.

[0027] For example, please refer to Figure 1 and Figure 3 Each surface of the door panel 3 is affixed with a 2mm thick anti-vibration plate 8, and the two largest surfaces of the door panel 3 are fixedly connected to two steel plates 9 respectively.

At the same time, under the action of the steel plate 9 and the reinforced partition 10, the door panel 3 has better impact resistance, and the structure will not be easily destroyed under external force collision, thereby improving the safety of the civil defense door.

[0029] The working process of the utility model: using a radiation-proof and sound-insulating composite functional civil air defense door designed by the present invention, when the door panel 3 is closed, the magnetic plate 4 and the magnet 5 are fitted together, and at this time the controller energizes the magnetic plate 4, so that the magnetic plate 4 and the magnet 5 are tightly attracted together, and at the same time cooperates with the handwheel door lock 6 to lock the door panel 3, so that the entire door panel 3 is more stable and reliable after closing the door, and after closing the door, the metal noise generated by the vibration of the door panel 3 can be effectively filtered under the action of the anti-vibration plate 8 and the sound insulation cotton 11, and at the same time, under the action of the steel plate 9 and the reinforced partition 10, the door panel 3 has better impact resistance, and the structure will not be easily destroyed under the impact of external force, thereby improving the safety of the civil air defense door.

[0030] In summary, the device is configured to generate metallic noise when vibrating, and at the same time, the structure will not be easily destroyed under external force impact, thereby improving the safety of the civil air defense door.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
