Description

Technical Field

[0001] This utility model relates to the field of civil defense door technology, specifically a dustproof and sealed civil defense door. Background Technology

[0002] Civil defense, also known as civil defense, refers to the activities of the government in mobilizing and organizing the masses to take measures to prevent air raids, fight disasters and provide relief, carry out rescue operations, and prevent and mitigate the harm of disasters. Civil defense doors are a type of civil defense protective equipment.

[0003] In the prior art, such as the civil defense door panel proposed in patent application number "CN202222474945.X", a door panel body is provided, including: a lightweight layer filled inside the door panel body to slow down the propagation of the blast shock wave, a reinforcing layer wrapped around the lightweight layer, and a flame-retardant layer wrapped around the reinforcing layer. The flame-retardant layer is disposed on the surface of the door panel body. Both the reinforcing layer and the flame-retardant layer are used to block explosive fragments and prevent the spread of combustion. The flame-retardant layer is a spray-applied coating, and the spray-applied coating is one or more of spray-applied polyurethane, polyurethane urea, and spray-applied polyurea.

[0004] However, in the aforementioned patent, the existing airtight doors tend to accumulate thick dust on their surface during long-term use, affecting the aesthetics of the air defense door and increasing the corrosion rate of the air defense door surface. Therefore, it is necessary to clean the dust on the surface of the air defense door. However, the thick dust on the surface of the air defense door is not easy to clean, resulting in a slow dust cleaning speed. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof and sealed airtight door to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A dustproof and sealed air-raid shelter door includes a door frame and a cleaning assembly. A sealing door is rotatably installed on the inner side of the door frame, and a baffle is horizontally fixed at the upper end of the door frame.

[0008] The cleaning component includes a first hidden groove, which is opened on the inner side of the door frame. A motor is rotatably installed at the bottom of the first hidden groove. A threaded rod is fixedly installed on the upper surface of the motor. The upper end of the threaded rod is rotatably installed at the top of the first hidden groove. A lifting block is threaded on the outer surface of the threaded rod. The lifting block is slidably installed on the inner side of the first hidden groove.

[0009] Preferably, a movable block is fixedly provided at one end of the lifting block, and a rectangular placement groove is provided at the bottom of the door frame, with the movable block slidably disposed inside the placement groove.

[0010] Preferably, a second hidden groove is provided on the inner side of the door frame, one end of the moving block is slidably disposed on the inner side of the second hidden groove, and a rack is vertically fixedly disposed on the inner side of the second hidden groove.

[0011] Preferably, one end of the movable block is provided with a groove, and a transmission gear is rotatably arranged inside the groove, with the transmission gear meshing with one side of the rack.

[0012] Preferably, a mounting groove is provided on one side of the movable block, a mounting block is slidably disposed inside the mounting groove, a cleaning block is fixedly disposed on one side of the mounting block, and the cleaning block is slidably disposed on one side of the sealing door.

[0013] Preferably, the mounting block has two mounting bolts on its internal thread, and the lower threads of the two mounting bolts are located inside the movable block.

[0014] The beneficial effects of this utility model are:

[0015] This invention uses a motor and a threaded rod to drive the lifting block to move up and down, which in turn moves the cleaning block on the outer surface of the sealed door to clean a large amount of dust from the sealed door surface. This prevents the surface of the sealed door from accumulating thick dust that is difficult to clean and also prevents thick dust from causing serious corrosion to the surface of the air-raid shelter door.
