[0024] Embodiment

[0025] An embodiment of the present application provides a purification door with a double-sealing structure for a clean room, as Figure 1-2As shown in the figure, it includes a door body 1 and a frame body 2. The frame body 2 is a 1.5-mm aluminum alloy profile door frame with a door frame thickness of 50 mm. The door body 1 is a 1.0-mm galvanized steel door leaf with a door leaf thickness of 50 mm. A lock handle 11 is installed on the door leaf. A 304 stainless steel hinge 10 is used between the door leaf and the door frame. A first boss 3 and a second boss 4 are provided on the frame body 2. First grooves 5 and second grooves 6 are provided at the edge position of the door body 1. The first groove 5 is correspondingly arranged with the first boss 3, and the second groove 6 is correspondingly arranged with the second boss 4. The first boss 3 and the second boss 4 on the frame body 2, and the first groove 5 and the second groove 6 on the door body 1 are all continuous stepped structures. A first sealing strip 7 is fixedly arranged in the first groove 5, and a second sealing strip 8 is fixedly arranged in the second groove 6. When the purification door is closed, the first boss 3 is embedded in the first groove 5, and the second boss 4 is embedded in the second groove 6. The first sealing strip 7 is located between the first boss 3 and the first groove 5, and the second sealing strip 8 is located between the second boss 4 and the second groove 6. The first sealing strip 7 and the second sealing strip 8 are made of foamed silica gel strips. The surface of the first sealing strip 7 facing the first boss 3 is a smooth circular curved surface, and the surface of the second sealing strip 8 facing the second boss 4 is a smooth circular curved surface. The part of the surface of the first boss 3 pressing the first sealing strip 7 is an arc surface structure, and the part of the surface of the second boss 4 pressing the second sealing strip 8 is an arc surface structure. The convex surface of the arc structure enables the foamed rubber strip to be vertically downward in the force direction when being squeezed during opening and closing, reducing the risk of the rubber strip being squeezed and falling off. A viewing window 9 is provided on the door body 1. The viewing window 9 includes double-layer hollow toughened glass installed on the door body 1. The hollow viewing window 9 is convenient for users inside and outside the purification room to observe. At the same time, a floor sweeping strip is provided at the bottom of the door body 1. The length of the floor sweeping strip is equal to the width of the door body 1. The floor sweeping strip improves the sealing performance of the purification door.

[0026] A purification door with a double-sealing structure for a clean room provided by this application adopts a double-sealing structure in which two bosses and two grooves are matched and a sealing strip is arranged between them, improving the overall sealing performance of the purification door. The seal between the door frame and the door leaf is tight, which can effectively prevent the penetration of dust, bacteria and other particles, meets the national standard grade 8, has sufficient strength and structural stability, can withstand frequent use and a certain amount of external force impact, has good flame retardant performance, can effectively prevent the spread of fire in case of a fire, and buys time for personnel evacuation and fire fighting and rescue. The noise generated during opening and closing the door is small and will not interfere with the surrounding environment.
