The classification of civil air defense doors is relatively distinct, including various civil air defense equipment such as ordinary single and double-leaf protective airtight doors and airtight doors, and single and double-leaf protective airtight doors and airtight doors with movable thresholds. Civil air defense is also known as civil defense, so civil air defense doors belong to civil defense protection equipment. They are usually used in underground garages or underground shopping malls during peacetime. In case of fire or war, they can quickly close the entrance of the civil air defense project to achieve the protection effect.

[0003] Although the current civil air defense doors can achieve simple sealing, their airtightness is poor, and they cannot isolate smoke, fog, etc., which affects the protection effect. Moreover, their sealing rubber strips are prone to aging during long-term use, and it is not convenient to quickly replace the sealing rubber strips. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are some but not all of the embodiments of the present utility model, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0022] Please refer to Figures 1 - 4, the present utility model provides a technical solution: a sound-insulating civil air defense door with high sealing performance, including: a door panel 2 and a door frame 9. One end of the door panel 2 is rotatably connected to the door frame 9 through a hinge and is fixed to the door frame 9 through a door lock. A protective plate 1 is fixedly installed at one end of the door panel 2. The size of the protective plate 1 is larger than that of the door panel 2. The protective plate 1 and the door panel 2 are integrally formed. The door panel 2 is located at the center of one end of the protective plate 1. When the door panel 2 is closed within the door frame 9, the outer end of the protective plate 1 contacts the outer end of the door frame 9, adding an additional layer of sealing to make the sealing effect of the civil air defense door better. Sound-absorbing cotton 4 is provided at the inner ends of the protective plate 1 and the door panel 2. Both the protective plate 1 and the door panel 2 are made of steel plates. Cavities 3 are provided at the inner ends of the protective plate 1 and the door panel 2. The sound-absorbing cotton 4 is located within the cavities 3. The steel plates can enhance the firmness of the civil air defense door and its fire and explosion resistance capabilities. The sound-absorbing cotton 4 makes the civil air defense door have a sound-insulating effect. Sealing rings one 7 are installed on the outer sides of one end of the protective plate 1 and the door panel 2 respectively. The double sealing rings one 7 achieve a double-sealing effect.

[0023] Installation blocks 5 are fixedly installed on the outer sides of one end of the protective plate 1 and the door panel 2 respectively. The installation blocks 5 are convex-shaped. Guide slopes 6 are provided on the upper and lower sides of the outer ends of the installation blocks 5. By providing the guide slopes 6, it is convenient for the socket grooves 8 to be sleeved on the outer ends of the installation blocks 5. A socket groove 8 is provided at one end of the sealing ring one 7. The socket groove 8 is convex-shaped. The socket groove 8 is sleeved on the outer end of the installation block 5 by expanding itself, thereby installing the sealing ring one 7 well and simultaneously playing a role in facilitating the quick replacement of the sealing ring one 7.

[0024] A door opening 10 is provided at one end of the door frame 9. The size of the door opening 10 is larger than that of the door panel 2 and smaller than that of the protective plate 1. Sealing rings two 12 are fixedly installed at one ends of the door frame 9 and the door opening 10 respectively. Connection grooves 11 are provided on the outer sides of one ends of the door frame 9 and the door opening 10. The width of the connection grooves 11 is the same as the width of the sealing rings two 12. A rubber ring 13 is fixedly installed at one end of the sealing ring two 12. The sealing ring two 12 is inserted and fixed in the connection groove 11 by squeezing the rubber ring 13, thereby fixing the sealing ring two 12 and simultaneously playing a role in facilitating the quick disassembly and assembly of the sealing ring two 12. The sealing rings one 7, the sealing rings two 12, and the rubber ring 13 are all made of fireproof rubber.

[0025] When the door panel 2 is located within the door opening 10, the two sealing rings one 7 are respectively in contact with the side walls of the door opening 10 and the door frame 9, and the two sealing rings two 12 are respectively in contact with the side walls of the protective plate 1 and the door panel 2, making the civil air defense door have a quadruple-sealing effect and increasing the sealing performance of the civil air defense door.

[0026] In actual use, the socket groove 8 is sleeved on the outer end of the mounting block 5 by expanding itself, so as to respectively install the first sealing ring 7 on the side walls at one ends of the guard plate 1 and the door panel 2. Then, the two second sealing rings 12 are fixed to one ends of the door opening 10 and the door frame 9 by extruding the rubber ring 13. After the door panel 2 is pushed into the door opening 10 and locked by the door lock, the two first sealing rings 7 are respectively in contact with the side walls of the door opening 10 and the door frame 9, and the two second sealing rings 12 are respectively in contact with the side walls of the guard plate 1 and the door panel 2, so as to perform quadruple sealing on the civil air defense door.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
