[0029] The sleeve 6 is installed on the door frame above the door panel through the door frame mounting plate 5, the upper mounting plate 3 is installed on the upper end of the door panel, and the outer shell 4 is embedded in the door panel. The upper rotating shaft 17 is moved horizontally by adjusting the component so that the upper rotating shaft 17 corresponds to the sleeve 6, and then the adjusting component adjusts the upper rotating shaft 17 to rise and insert it into the sleeve 6 for rotation, so that the upper end of the door panel is rotatably connected to the door frame.

[0030] The door bottom rotating assembly is located below the door top rotating assembly 1, and the door bottom rotating assembly includes a lower mounting plate 7, a lower rotating shaft 9, a snap-in block 8, a support block 10 and a ground mounting plate 11. The snap-in block 8 is fixedly arranged on the upper end of the lower mounting plate 7, and the lower rotating shaft 9 is rotatably mounted on the lower mounting plate 7. The lower end of the lower rotating shaft 9 is fixedly connected to the support block 10 located below the lower mounting plate 7, and the center of the support block 10 is located on the center line of the lower rotating shaft 9. The ground mounting plate 11 is located below the lower mounting plate 7, and a mounting hole 38 matching the support block 10 is opened on the ground mounting plate 11.

[0031] The ground mounting plate 11 is fixedly mounted on the ground, the lower mounting plate 7 is mounted on the lower end of the door panel, the snap-in block 8 is embedded in the door panel, and the support block 10 at the lower end of the lower rotating shaft 9 is snapped into the mounting hole 38, thereby connecting the lower rotating shaft 9 on the door panel with the ground mounting plate 11 installed on the ground, thereby realizing the rotational connection between the door panel and the ground.

[0032] In the above manner, the sleeve can first be installed separately on the door frame through the door frame mounting plate, and then the upper rotating shaft can be adjusted to move left and right through the adjusting component to align with the sleeve, and the upper rotation can be adjusted to rise through the adjusting component so as to be inserted into the sleeve and rotated, thereby facilitating the installation of the central axis door and facilitating subsequent separate disassembly, maintenance and replacement.

[0033] Further, the adjustment assembly includes an adjustment plate 18, a first fixed block 14, a moving block 16, a first pusher and a second pusher; the adjustment plate 18 is movably arranged in the housing 4, the moving direction of the adjustment plate 18 is arranged along the length direction of the housing 4 and the upper mounting plate 3, the adjustment plate 18 is arranged sideways, the length of the adjustment plate 18 is parallel to the length of the mounting plate, the first fixed block 14 is fixedly installed at the lower end of the upper mounting plate 3, the first pusher is installed at one end of the housing 4 and connected to the first fixed block 14, the second pusher is installed at one end of the housing 4 and connected to the adjustment plate 18, and the pushing directions of the first pusher and the second pusher are parallel to the length direction of the upper mounting plate 3;

[0034] The moving block 16 is located in the shell 4 and is fixedly connected to the upper rotating shaft 17. The moving block 16 is provided with a first sliding column 24 protruding toward one side of the shell 4 and perpendicular to the length direction of the shell 4. The adjusting plate 18 is provided with an inclined sliding hole 25 through which the first sliding column 24 passes. The shell 4 is provided with a vertical sliding hole 26 through which the first sliding column 24 passes. The inclined sliding hole 25 intersects with the projection of the vertical sliding hole 26.

Through the connection between the second pusher and the adjusting plate 18, the horizontal movement of the housing 4 will drive the adjusting plate 18 to move synchronously. Therefore, the synchronous movement of the housing 4 and the adjusting plate 18 makes there is no relative displacement between the housing 4 and the adjusting plate 18. The first slide column 24 is clamped by the intersection of the vertical slide hole 26 on the housing 4 and the inclined slide hole 25 on the adjusting plate 18, thereby driving the first slide column 24 to move. Thereby, the moving block 16 connected to the first sliding column 24 and the upper rotating shaft 17 are driven to move horizontally, so that the horizontal position of the upper rotating shaft 17 is adjusted by the first pushing member to align it with the shaft sleeve 6, and because the second sliding column 27 on the first fixed block 14 passes through the first horizontal sliding hole 28 on the adjustment plate 18 and the second horizontal sliding hole 29 on the shell 4 in sequence, the adjustment plate 18 and the shell 4 are clamped on the upper mounting plate 3 through the restriction of the second sliding column 27 and will not fall downward, so that the shell 4 and the adjustment plate 18 only have a structure that moves in the horizontal direction.

[0036] If the first pushing member is stationary, there will be no relative displacement between the shell 4 and the fixed block, and the position of the shell 4 will be fixed, and the horizontal position of the upper rotating shaft 17 will be fixed; the adjusting plate 18 is pushed by the second pushing member, and since the first sliding column 24 passes through the inclined sliding hole 25 of the adjusting plate 18, it will drive the first sliding column 24 to move, but at the same time, since the first sliding column 24 also passes through the vertical sliding hole 26 on the shell 4, the horizontal movement of the first sliding column 24 is limited by the vertical sliding hole 26, so that it can only move vertically, so that under the drive of the inclined sliding hole 25, the first sliding column 24 moves vertically along the vertical sliding hole 26, so that the upper rotating shaft 17 is adjusted to move vertically through the moving block 16 connected to the first sliding column 24, so as to insert the upper rotating shaft 17 into the shaft sleeve 6.

The size of the adjusting hole 23 is smaller than the screw head size of the first adjusting screw 20 and the second adjusting screw 22.

[0038] When the first adjusting screw 20 is rotated, the housing 4 is moved due to the screw connection between the first adjusting screw 20 and the fixing block; when the second adjusting screw 22 is rotated, the adjusting plate 18 is moved due to the screw connection between the second adjusting screw 22 and the connecting block 21.

[0039] Furthermore, the adjustment plate 18 has a pin hole 34 , and the connection block 21 is provided with a pin column 33 inserted into the pin hole 34 .
