[0017] like Figures 1-4 As shown, a door frame structure of an airtight door includes a fixed frame 1 and a sealing frame 2. The fixed frame 1 is arranged in a rectangular frame. A groove 3 is opened in the middle of the inner wall of the fixed frame 1. The sealing frame 2 is fixedly connected to the inner wall of one end of the fixed frame 1 and is used to limit the movement of the door panel. A sealing airbag 4 is fixedly connected in the groove 3 and is used to seal the side wall of the door panel. A connecting groove 6 is opened on the side wall of the fixed frame 1 at one end away from the sealing frame 2. The connecting grooves 6 are symmetrically distributed in the upper and lower parts. The door panel is hinged in the connecting groove 6 and is buckled with the fixed frame 1. The sealing frame 2 limits one end of the door panel, and the sealing airbag 4 seals the other end side wall of the door panel.

[0018] like Figures 2-4 As shown, in order to improve the sealing effect between the door panel and the door frame, the cross-section of the sealing frame 2 is set to be trapezoidal, the cross-section of the sealing airbag 4 is set to be a right-angled triangle, the inclined surface of the sealing frame 2 and the inclined surface of the sealing airbag 4 are set opposite to each other, and the inclined surface of the sealing frame 2 contacts one end of the door panel to increase the inclined sealing surface of the door panel. The inclined surface of the sealing frame 2 is fixedly connected with a sealing strip 5, and the sealing strips 5 are arranged at uniform intervals. A plurality of sealing strips 5 are arranged in the inclined surface, and the sealing strips 5 are used to seal the joint between the door panel and the sealing frame 2, and provide a pressure buffering effect between the inclined surfaces to improve the sealing between the door panel and the door frame.

[0019] The outer side of the fixing frame 1 is fixedly connected with a positioning plate 7 , and the positioning plates 7 are symmetrically distributed in pairs up and down, and are used for positioning and installing the fixing frame 1 .

[0020] In use, the door plate is hinged to one side of the fixed frame 1 through the connecting slot 6, when the door plate is buckled with the fixed frame 1, one end of the door plate is in contact with the inclined surface of the sealing frame 2, the sealing rubber strip 5 on the inclined surface of the sealing frame 2 provides pressure buffering effect for the door plate, and the multi-stage sealing effect of the outer side of the one end of the door plate is increased, meanwhile, the outer side of the other end of the door plate is sealed by the sealing air bag 4 which is reversely inclined with the inclined surface of the sealing frame 2, the door plate is sealed between the inclined surface of the sealing frame 2 and the inclined surface of the sealing air bag 4, the outer side of both ends of the door plate is sealed, and the sealing effect between the door frame and the door plate is effectively improved.

[0021] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
