Technical Field
[0001] The utility model relates to the technical field of civil air defense doors, in particular to a civil air defense door structure. Background Technique
[0002] Civil air defense doors belong to civil air defense protection equipment. Such doors were the first to be standardized and have been widely selected. They are characterized by simple structure, reliable operation, and convenient maintenance, and are suitable for the entrances and exits of various civil air defense projects. However, due to their thresholds, they are less used in projects with frequent personnel and vehicle access, such as underground shopping malls that combine peacetime and wartime functions, and instead, movable threshold doors or drop-down doors with the same corresponding dimensions and load grades are used.
[0003] The internal structure of the existing civil air defense doors is relatively simple, and the radiation barrier to the outside is limited during use, reducing the practicality of the civil air defense doors.
[0004] Secondly, civil air defense doors with poor sound insulation are prone to allowing external noise to enter the civil air defense space, affecting people's work, rest, and study activities. Noise has a negative impact on human health and mental state, and may cause problems such as anxiety, sleep problems, and inattention, which will affect the work efficiency and productivity of employees, as well as the learning ability and concentration of students. Content of the Utility Model
[0005] The purpose of the utility model is to provide a civil air defense door structure to solve the problems raised in the background technique, namely, the relatively simple internal structure, the limited radiation barrier to the outside during use, reducing the practicality of the civil air defense door, and the poor sound insulation of the civil air defense door is prone to allowing external noise to enter the civil air defense space, affecting the lives of residents.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A civil air defense door structure includes a door frame. A sealing door is hinged to the right end of the front surface of the door frame, and a card slot is opened on the front surface of the door frame.
[0007] A sealing block is fixedly installed on the inner side of the sealing door, and a clamping block is fixedly installed on the inner side of the sealing door. A door opening is opened on the front surface of the door frame.
[0008] The sealing block can be embedded into the inside of the card slot. The inner wall of the card slot is made of rubber material. The sealing block is in the shape of a "return" character, and the sealing block is made of polytetrafluoroethylene material.
[0009] The clamping block can be embedded into the inside of the door opening. The surface of the clamping block is made of polytetrafluoroethylene material. Two sealing layers are fixedly installed on the inner side of the clamping block, and the sealing layers are made of metal sealing materials.
[0010] Preferably, a sound insulation layer is fixedly installed on the inner side of the sealing layer. The sound insulation layer is made of sound insulation board material, and the inner side of the sound insulation layer is hollow.
[0011] Preferably, the surface of the sealing door is made of polycarbonate, and an isolation layer is fixedly installed inside the sealing door, and the material of the isolation layer is lead.
[0012] Preferably, a protective layer is fixedly installed inside the isolation layer, and the material of the protective layer is tungsten.
[0013] Preferably, a strengthening layer is fixedly installed inside the protective layer, and the material of the strengthening layer is graphite.
[0014] Compared with the prior art, the beneficial effects of the present utility model are:
[0015] 1. For the structure of this civil air defense door, by setting the sealing block to be embedded in the card slot for splicing, when the rubber material card slot is connected, the sealing performance is better. The sealing block is made of polytetrafluoroethylene, which is a material with low friction, high temperature resistance and corrosion resistance. It has excellent anti-chemical corrosion performance and can maintain good sealing performance within a wide temperature range, effectively improving the sealing performance of the product and effectively reducing the transmission of noise. The product is closed by the clamping block being embedded in the inner wall of the door opening. The sealing layer of the clamping block is a metal sealing material, which has good pressure resistance, corrosion resistance and high temperature resistance, further enhancing the stability of the product. By setting the sound insulation layer for further sound insulation, the sound insulation effect of the product is effectively enhanced, and the influence of noise on the lives of residents is effectively reduced.
[0016] 2. Secondly, for the structure of this civil air defense door, by setting the isolation layer for radiation protection, the material of the isolation layer is lead. Lead has a high density and absorption capacity and is one of the most commonly used radiation protection materials, effectively improving the radiation protection ability of the product. By setting the protective layer for further radiation protection, tungsten has a high density and can effectively absorb X-rays and γ-rays, further improving the radiation protection ability of the product. Setting the strengthening layer effectively enhances the radiation protection ability of the product. Graphite is a material with good electrical conductivity and can be used to shield electromagnetic radiation, making the radiation protection ability of the product stronger, effectively improving the safety of the product and the practicality of the civil air defense door.
