[0036] Now, the present utility model will be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present utility model in a schematic manner, so it only shows the components related to the present utility model.

[0037] Please refer to Figure 1-8 , the present utility model provides a technical solution: a stainless steel double-opening weatherproof and airtight door, including a door frame 1, a first door panel 2 and a second door panel 3.

[0038] A limit frame 11 is provided inside the door frame 1, and a frame groove 1101 is opened on the limit frame 11.

[0039] One side of the first door panel 2 is hinged to one side of the limit frame 11, and one side of the second door panel 3 is hinged to the other side of the limit frame 11. When the first door panel 2 and the second door panel 3 are closed on the door frame 1, the sides of the first door panel 2 and the second door panel 3 are in contact with each other.

[0040] When the first door panel 2 is closed on the door frame 1, the edge of its end face abuts against the limit frame 11. A first sealing strip 23 is provided at the position where the first door panel 2 abuts against the limit frame 11. The first sealing strip 23 is embedded in the frame groove 1101. A strip-shaped groove 201 is formed on the side edge of the first door panel 2 where it abuts against the second door panel 3. A rotating shaft 21 is fixed on the end face of the first door panel 2 away from the limit frame 11. An arcuate strip 22 is provided on the rotating shaft 21. One end of the arcuate strip 22 is rotatably connected to the rotating shaft 21. A hand rocker 221 is fixed on the arcuate strip 22. A second sleeve 222 is sleeved on the hand rocker 221. An arc-shaped groove 2201 is formed in the concave side of the arcuate strip 22.

[0041] When the second door panel 3 is closed on the door frame 1, the edge of its end face abuts against the limit frame 11. A second sealing strip 32 is provided at the position where the second door panel 3 abuts against the limit frame 11. The second sealing strip 32 is embedded in the frame groove 1101. An inner groove 302 is formed on the side edge of the second door panel 3 where it abuts against the first door panel 2. The inner groove 302 penetrates through both ends of this side edge of the second door panel 3. A sealing gasket 31 is provided in the inner groove 302. Several springs 313 are provided on the side of the sealing gasket 31 close to the bottom wall of the inner groove 302. One end of the spring 313 away from the sealing gasket 31 is connected to the bottom wall of the inner groove 302. A transverse through groove 301 is formed on the end face of the second door panel 3 away from the limit frame 11. The transverse through groove 301 is communicated with the inner groove 302. A lever 311 is provided on the sealing gasket 31. The lever 311 passes through the transverse through groove 301. A first sleeve 312 is sleeved on the lever 311.

[0042] When the first door panel 2 and the second door panel 3 are closed on the door frame 1, the first sealing strip 23 and the second sealing strip 32 are embedded in the frame groove 1101, so that the side seams between the first door panel 2 and the second door panel 3 and the door frame 1 are sealed. Then, by rotating the arcuate strip 22, the concave side of the arcuate strip 22 abuts against the outer side of the first sleeve 312. Then, the arcuate strip 22 is pressed down. With the concave side of the arcuate strip 22 pressing against the first sleeve 312, the lever 311 is driven to move horizontally. The lever 311 drives the sealing gasket 31 to move outwards from the inner groove 302 and be embedded in the strip-shaped groove 201 of the first door panel 2, sealing the gap between the first door panel 2 and the second door panel 3, thereby overall enhancing the sealing performance of the weatherproof door.

[0043] By adding the hand rocker 221, it is more convenient to rotate and press down the arcuate strip 22. And by setting the second sleeve 222 outside the hand rocker 221, it is beneficial to hold the second sleeve 222 to operate the hand rocker 221.

[0044] In addition, a first sleeve 312 is added to the lever 311. After the concave side of the bow-shaped strip 22 abuts against the outer side of the first sleeve 312 and the bow-shaped strip 22 is pressed down, the concave side of the bow-shaped strip 22 moves horizontally against the lever 311 in a way of rotational friction with the first sleeve 312. In this way, the wear between the bow-shaped strip 22 and the first sleeve 312 is small, and the first sleeve 312 is also easy to replace after being worn.

[0045] Moreover, the arc-shaped groove 2201 formed in the concave side of the bow-shaped strip 22 can make the first sleeve 312 embed in the arc-shaped groove 2201 when the bow-shaped strip 22 is pressed down, and the first sleeve 312 is buckled in the arc-shaped groove 2201, so that the gasket 31 is stably embedded in the strip-shaped groove 201 to fill the gap between the first door panel 2 and the second door panel 3.

[0046] By arranging a plurality of springs 313 between the gasket 31 and the bottom wall of the built-in groove 302, the gasket 31 can reset itself under the pulling force of the springs 313 when the bow-shaped strip 22 is withdrawn.

[0047] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
