In order to solve the technical problem, the utility model discloses a technical scheme be: the prefabricated cabin door sealing structure comprises a fixed door frame, wherein a fixed inner frame is fixedly connected to the rear end of the inner wall of the fixed door frame, and two fixed rotating shafts are fixedly connected to one side of the front end of the inner wall of the fixed door frame;

the outer walls of the two fixed rotating shafts are rotatably connected with rotating strips, one sides of the two rotating strips far away from the fixed rotating shafts are fixedly connected with a door body, and a protection plate is fixedly connected to the front of the door body;

the door body is installed the rubber rectangular near the rear end of rotating strip one side, the door body is in the first rubber ring of one side difference fixedly connected with and the second rubber ring of keeping away from the guard plate, the top fixedly connected with protection blend stop of fixed door frame.

The utility model discloses further set up to: two grooves corresponding to the rotating strips are formed in the front end of one side of the inner wall of the fixed door frame.

Through the technical scheme, the two rotating strips are guaranteed to rotate on the two fixed rotating shafts, and then the integral rotation of the door body is realized.

The utility model discloses further set up to: the length and the width of the protection plate are both larger than those of the door body.

Through the technical scheme, when the door body is closed, the protection plate is tightly attached to the fixed door frame, and therefore it is guaranteed that external sand blown by the wind and dust cannot directly enter the space between the door body and the fixed door frame.

The utility model discloses further set up to: and one side of the inner wall of the fixed door frame is provided with a groove corresponding to the rubber strip.

Through the technical scheme, when the door body is closed, the rubber strip is extruded and tightly attached to the groove in the fixed door frame, and further sealing of the rotating position of the door body and the fixed door frame is achieved.

The utility model discloses further set up to: the front of the fixed inner frame is respectively provided with a groove corresponding to the first rubber ring and the second rubber ring.

Through above-mentioned technical scheme, first rubber ring and second rubber ring compress tightly with the recess on the fixed inside casing under the extrusion of the door body, and then make and form double-deck sealed between fixed inside casing and the door body, and the cooperation of recess and first rubber ring and second rubber ring makes sealed effect better.

The utility model has the advantages as follows:

1. the utility model discloses a simple rubber of department design is rectangular at the rotation of the door body and fixed door frame. The door body and the fixed door frame are further sealed, and the phenomenon that outside air enters the prefabricated cabin through gaps is avoided.

2. The utility model designs the first rubber ring and the second rubber ring, which are pressed with the groove on the fixed inner frame under the extrusion of the door body, so that a double-layer seal is formed between the fixed inner frame and the door body, and the sealing effect is better due to the matching of the groove with the first rubber ring and the second rubber ring;

3. the utility model discloses a design guard plate and protection blend stop have further played the effect of protection to external sand blown by the wind and rainwater, avoid between its direct gap that gets into fixed door frame and the door body.
