[0030] The outer plate 40 includes a plate body 41 and a positioning portion 42 connected to the plate body 41. The positioning portion 42 is arranged in a frame-shaped structure. The positioning portion 42 includes a first connecting piece 421 and a second connecting piece 422 connected to the first connecting piece 421. The second connecting piece 422 is distributed in an L shape with the first connecting piece 421. The side of the second connecting piece 422 away from the first connecting piece 421 is connected to the plate body 41. The first connecting piece 421 and the plate body 41 are arranged opposite to each other in the horizontal direction.

[0031] The positioning frame 50 is also arranged in a frame-shaped structure, and the positioning frame 50 includes a first positioning plate 51, a second positioning plate 52, and a third positioning plate 53 connecting the first positioning plate 51 and the second positioning plate 52. The third positioning plate 53 is continuously bent, and the first positioning plate 51 and the second positioning plate 52 are respectively vertically connected to the two ends of the third positioning plate 53, and the first positioning plate 51 and the third positioning plate 53 are staggered in the height direction.

[0032] The sealing strip 70 is also arranged in a frame-like structure as a whole. The sealing strip 70 includes a sealing plate 71, a main body 72 connected to one side of the sealing plate 71, a connecting edge 73 connected to the other side of the sealing plate 71, and a limiting edge 74 connected to the connecting edge 73 away from the sealing plate 71. The main body 72 is arranged in an arch shape, and a hollow groove 76 is formed between the main body 72 and the sealing plate 71. The hollow groove 76 is distributed along the extension direction of the sealing strip 70. The limiting edge 74 is arranged opposite to the sealing plate 71. The limiting edge 74, the sealing plate 71 and the connecting edge 73 are distributed in an I-shape, and slots 75 are formed on both sides of the connecting edge 73 (i.e., the inner and outer sides of the sealing strip 70).

[0033] During assembly, the second positioning plate 52 of the positioning frame 50 is installed on the back of the plate body 41 by welding or screwing, the first positioning plate 51 and the first connecting piece 421 are arranged opposite to each other in the vertical direction, a gap is formed between the first positioning plate 51 and the first connecting piece 421, the connecting edge 73 of the sealing strip 70 passes through the gap, the first positioning plate 51 and the first connecting piece 421 are respectively stuck in the two card grooves 75 of the sealing strip 70, the sealing plate 71 and the limiting edge 74 are stuck in the positions on both sides of the gap, so that the sealing strip 70 is installed between the outer plate 40 and the positioning frame 50. In addition, the outer periphery of the embedded part 60 is provided with a plate edge 61, and the plate edge 61 of the embedded part 60 is installed on the third positioning plate 53 of the positioning frame 50 by welding or screwing.

[0034] The door frame 20 is provided with a door groove 21 that runs through the front and back, and the position of the door frame 20 at the periphery of the door groove 21 is a frame edge 72. When the door leaf 10 is in a closed state on the door frame 20, the main body 72 of the sealing strip 70 is sandwiched between the frame edge 72 of the positioning frame 50 and the door leaf 10, and the sealing strip 70 is arranged around the periphery of the notch of the entire door groove 21, thereby improving the sealing performance when the door frame 20 and the door leaf 10 cooperate. The hollow groove 76 on the sealing strip 70 can effectively improve the expansion and contraction performance of the sealing strip 70, so that when part of the surface of the sealing strip 70 is worn, the overall sealing performance can still be guaranteed. In addition, the setting of the positioning frame 50 and the reinforcement frame 80 may improve the overall strength of the door leaf 10.

[0035] The beneficial effect of the waterproof passage door of the utility model is that: by setting the first connecting piece 421 on the outer plate 40 of the door leaf 10, setting the first positioning plate 51 on the positioning frame 50 of the door leaf 10, the inner and outer sides of the sealing strip 70 are provided with a card groove 75, the first positioning plate 51 and the first connecting piece 421 are respectively stuck in the two card grooves 75 of the sealing strip 70, and the sealing strip 70 extends to the rear side of the outer plate 40. When the door leaf 10 is in a closed state on the door frame 20, the main body 72 of the sealing strip 70 is clamped between the frame edge 72 of the positioning frame 50 and the door leaf 10, thereby improving the sealing performance when the door frame 20 and the door leaf 10 cooperate. It is highly practical and has a strong promotion significance.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
