[0026] Please refer to Figures 1-6 , the present invention provides a sealing door structure for a cultural and tourism cabin, including a cabin door frame body 1 and a main sealing door panel 3. The front side wall of the cabin door frame body 1 is hinged and installed with the main sealing door panel 3 through a hinge 2. A sealing plate 31 is installed on the rear side wall of the main sealing door panel 3. A through hole is opened on the surface of the cabin door frame body 1. An inlaid convex seat plate 32 for sealing the through hole is installed on the rear side wall of the sealing plate 31. A sealing device 6 for sealing is arranged between the cabin door frame body 1 and the main sealing door panel 3. A rotating handle 5 for controlling the sealing of the main sealing door panel 3 is rotationally installed on the front side wall of the main sealing door panel 3 and at the middle position. A supporting handle 4 for pushing the main sealing door panel 3 to move is installed on the front side wall of the main sealing door panel 3 and above the rotating handle 5.

[0027] Further, the sealing device 6 includes a mounting groove 61, a positioning clamping rod 62, a mounting seat 63, a clamping notch 64, a clamping arc plate 65, a toothed ring 66, a transmission rack plate 67, a power gear 68, a meshing gear 69, a transmission gear seat 70, a rotating push rod 71 and a transmission connecting rod 72. The mounting groove 61 is formed on the front side wall of the cabin door frame 1 and is located on the right side of the passage opening. The positioning clamping rod 62 is installed inside the mounting groove 61 and is located at the front side position. The mounting seat 63 is installed on the rear side wall of the main sealing door panel 3. The clamping notch 64 is formed at the rear end of the mounting seat 63. The clamping arc plate 65 is rotatably installed on the mounting seat 63 through a bearing. The toothed ring 66 is installed on the outer wall of the clamping arc plate 65. A transverse sliding groove is formed on the rear side wall of the main sealing door panel 3. The transmission rack plate 67 is clamped on the rear side wall of the main sealing door panel 3 through the transverse sliding groove. The transmission rack plate 67 meshes with the toothed ring 66. The power gear 68 is rotatably installed on the rear side wall of the main sealing door panel 3 through a bearing and is located at the middle position. The rear end of the rotating handle 5 penetrates through the main sealing door panel 3 and is installed at the axial center position of the front side wall of the power gear 68. The meshing gear 69 is rotatably installed on the rear side wall of the main sealing door panel 3 through a bearing and is located below the power gear 68. The power gear 68 meshes with the meshing gear 69. The transmission gear seat 70 is rotatably installed on the rear side wall of the main sealing door panel 3 through a bearing and is located below the meshing gear 69. The rotating push rod 71 is installed on the rear side wall of the transmission gear seat 70. The two ends of the transmission connecting rod 72 are respectively movably connected to the end of the rotating push rod 71 and the end of the transmission rack plate 67 through a pin shaft.

[0028] Further, the clamping arc plate 65 is cylindrical, and a notch equal to its inner diameter is formed on the rear side of the cylinder. The clamping arc plate 65 is clamped with the positioning clamping rod 62 through the notch on the rear side.

[0029] Further, the inner diameter of the clamping arc plate 65 is equal to the diameter of the positioning clamping rod 62. After the clamping arc plate 65 and the positioning clamping rod 62 are clamped, the two are sleeved and limited to cooperate to fix the main sealing door panel 3, so that the main sealing door panel 3 cannot be offset in the left - right and up - down directions, further improving the sealing effect.

[0030] Further, the central axis of the positioning clamping rod 62 is located in the plane of the front side of the cabin door frame 1, and the central axis of the clamping arc plate 65 is located in the plane of the rear side of the sealing plate 31. After the positioning clamping rod 62 and the clamping arc plate 65 are clamped, the front side of the cabin door frame 1 is in contact with the rear side of the inlaid convex seat plate 32, and the sealing gasket between the two is pressed to achieve the sealing effect.

[0031] Further, the rear - side edges of the clamping arc plate 65 and the clamping notch 64 are both rounded to facilitate the clamping of the clamping notch 64 and the clamping arc plate 65 with the positioning clamping rod 62.

[0032] Further, sealing washers are installed on the outer side wall of the inlaid convex seat plate 32 and the rear side wall of the sealing plate 31.

[0033] During use, the sealing main door panel 3 is pushed to rotate along the hinge 2 by holding the support handle 4 to open it. Personnel can move in and out through the access opening inside the cabin door frame 1. When it is necessary to close the cabin door, hold the support handle 4 and push the sealing main door panel 3 to rotate along the hinge 2, control the sealing main door panel 3 to rotate to the front side wall of the cabin door frame 1, and control the sealing plate 31 to approach the surface of the cabin door frame 1, so that the inlaid convex seat plate 32 is inserted into the inner side of the access opening. At this time, the sealing main door panel 3 drives the clamping notch 64 of the mounting seat 63 to be clamped on the outer side of the positioning clamping rod 62, and at the same time, the opening on the rear side wall of the clamping arc plate 65 is also clamped on the outer side of the positioning clamping rod 62. Then, manually rotate the rotating handle 5, drive the power gear 68 to rotate through the rotating handle 5. When the power gear 68 rotates, drive the transmission gear seat 70 to rotate through the meshing gear 69. The transmission gear seat 70 drives the rotating push rod 71 to rotate. When the rotating push rod 71 rotates, the outer end of it pushes the transmission rack plate 67 to move outward through the transmission connecting rod 72. When the transmission rack plate 67 moves, drive the toothed ring 66 to rotate through the teeth on its surface. The toothed ring 66 drives the clamping arc plate 65 to rotate. When the clamping arc plate 65 rotates, push the clamping arc plate 65 to move backward and close to the positioning clamping rod 62 through the notch surface opened on its rear side wall. As the clamping arc plate 65 rotates, the positioning clamping rod 62 is inserted into the innermost sides of the clamping notch 64 and the clamping arc plate 65, so that the outer wall of the positioning clamping rod 62 is completely attached to the inner wall of the clamping arc plate 65. At this time, pull the mounting seat 63 and the sealing main door panel 3 to approach the cabin door frame 1 through the clamping arc plate 65, so that the sealing plate 31 and the inlaid convex seat plate 32 are completely attached to the cabin door frame 1, thereby realizing the operation of closing the door and sealing, and the operation is simple and convenient to use.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
