[0027] The left side of the outer door 103 and the right side of the inner door 101 are both provided with self-locking components 2, and the middle position of the door frame 1 is provided with a sealing mechanism 3;

[0028] The self-locking assembly 2 includes two connecting strips 201 respectively fixedly connected to the sides of the outer door 103 and the inner door 101, and the other end of the connecting strip 201 is fixedly connected to the limit hook 202, and the two sides of the limit hook 202 are respectively engaged with the first clamping plate 203 and the second clamping plate 204;

[0029] The middle portion of the first clamping plate 203 is rotatably connected to the middle portion of the second clamping plate 204 .

[0030] The first clamping plate 203 and the second clamping plate 204 are fixedly connected with a return spring 210 on the outer side of one end close to the limit hook 202, and the first clamping plate 203 and the second clamping plate 204 are fixedly connected with a slide rail 207 on the side away from the limit hook 202. The connection between the first clamping plate 203 and the second clamping plate 204 is penetrated by an axial column, and the axial column is fixedly connected to the inner side of the door frame 1; the first clamping plate 203 and the second clamping plate 204 are rotatably connected with the axial column, and the return spring 210 will tilt and shrink when the first clamping plate 203 and the second clamping plate 204 rotate.

[0031] The slide rail 207 on the first clamping plate 203 is slidably connected to the first moving block 208, and the slide rail 207 on the second clamping plate 204 is slidably connected to the second moving block 209; the pull tube 205 is penetrated and connected on both sides of the door frame 1, and the pull tube 205 is rotatably connected to the first moving block 208. The inside of the pull tube 205 is penetrated and connected to the pull rod 206, and the other end of the pull rod 206 penetrates the first clamping plate 203 and is rotatably connected to the second moving block 209. One end of the outer end of the pull rod 206 is fixedly connected to a pressure plate 212, and one end of the pull tube 205 of the pull tube 205 is fixedly connected to a pull plate 211. The pull rod 206 can slide on the first clamping plate 203. The lengths of the pull tubes 205 and the pull rods 206 on both sides of the door frame 1 are different to adapt to the distance between the first clamping plate 203 and the second clamping plate 204 and the outside of the door frame 1.

[0032] The connecting strip 201 is fixedly connected with a partition plate 213, and shock-absorbing sponges 214 are fixedly connected inside the two sides of the door frame 1. The partition plate 213 overlaps with the shock-absorbing sponge 214. The sealing mechanism 3 includes a fixed strip 303 located between the two tracks 102 and in the middle of the door frame 1. The fixed strip 303 is fixedly connected to the door frame 1.

[0033] The sealing mechanism 3 also includes two separation springs 301 fixedly connected to the inner door 101 and the outer door 103 respectively. The separation spring 301 is located on the side closest to the fixing strip 303 when the outer door 103 and the inner door 101 are closed. A first sealing rubber pad 302 is fixedly connected in the gap between the separation spring 301 and the outer door 103, and a second sealing rubber pad 304 is fixedly connected to the side of the fixing strip 303 close to the separation spring 301; thereby, the separation spring 301, the first sealing rubber pad 302 and the fixing strip 303 form a compact sealing body, thereby increasing the sealing between the two doors, and during the deformation process of the separation spring 301, it can squeeze the first sealing rubber pad 302 to decelerate and buffer the movement of the door, thereby reducing the impact of the partition plate 213 and the shock-absorbing sponge 214.

[0034] A sealing strip 309 is inserted into the gap between the bottom of the inner door 101 and the outer door 103 near the outside and the door frame 1. The sealing strip 309 is fixedly connected to a movable plate 308. The movable plate 308 is fixedly connected to a stud 307. The movable plate 308 is slidably connected to the bottom of the door frame 1. The stud 307 is threadedly connected to a rotating sleeve 306. The rotating sleeve 306 is rotatably connected to a mounting side plate 305 fixedly connected to the bottom of the door frame 1. The sealing strip 309 is set in an L shape, and its bottom is inserted into the door frame 1 and the inner door 101. The gap between the door 101 or the outer door 103, whose vertical surface is in contact with the inner door 101 or the outer door 103, rubs against the inner door 101 or the outer door 103 as it is opened, causing wear of the sealing strip 309 and reduced sealing. At this time, the rotating sleeve 306 is rotated to move the movable plate 308 and push the sealing strip 309. Since the sealing strip 309 is made of rubber, the sealing strip 309 is slightly deformed during the movement and fits against the inner door 101 or the outer door 103 again.

[0035] Working principle: Before using this kind of household door sealing structure, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5 As shown, when the inner door 101 or the outer door 103 moves and is inserted into both sides of the door frame 1, the limit hook 202 squeezes the first clamping plate 203 and the second clamping plate 204 to rotate outward, and then the first clamping plate 203 and the second clamping plate 204 clamp the limit hook 202 under the push of the return spring 210;

[0036] If the inner door 101 or the outer door 103 is to be opened, the pull plate 211 and the pressure plate 212 are kneaded, so that the pull rod 206 pulls the second moving block 209 to slide on the slide rail 207, and the pull tube 205 pulls the first moving block 208 to move, and finally the first clamping plate 203 and the second clamping plate 204 are opened, and the clamping of the limit hook 202 is cancelled, so that the inner door 101 or the outer door 103 can be moved;

[0037] When the inner door 101 or the outer door 103 is closed, the separation spring sheet 301 thereon will first contact the second sealing rubber pad 304, so that the separation spring sheet 301 is deformed and squeezes the first sealing rubber pad 302, so that the separation spring sheet 301, the first sealing rubber pad 302 and the fixing strip 303 form a compact sealing body;

[0038] When the sealing strip 309 is worn due to long-term friction with the outer door 103 or the inner door 101, resulting in airtightness problems, the rotating sleeve 306 can be rotated to move the stud 307, thereby pushing the movable plate 308 to make the sealing strip 309 close to the inner door 101 or the outer door 103.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
