[0028] The limiting component 8 has a long rod 82 connected to the internal thread of the base 4, and one end of the long rod 82 matches the limiting slot 84 reserved in the circular bottom plate 3, and the other end of the long rod 82 is fixedly connected to a hand wheel 81, and the matching of the long rod 82 and the limiting slot 84 plays a limiting role on the circular bottom plate 3.

[0029] A circular groove 5 is reserved inside the base 4, and the circular groove 5 is open. The annular side wall and the bottom wall of the circular bottom plate 3 are in contact with and rotatably connected to the inner wall of the open circular groove 5, which facilitates the rotation of the overall structure of the body 1 fixedly connected to the circular bottom plate 3. When installing the magnetic levitation centrifugal chiller body 1, it is convenient to fine-tune the angle of the magnetic levitation centrifugal chiller body 1 for installation and subsequent use.

[0030] The inclined rod 71 is composed of three rod bodies, and the rod bodies at the upper and lower ends of the inclined rod 71 are vertical rod bodies, and the rod body in the middle part of the inclined rod 71 is in an inclined state.

[0031] The rod body at the upper end of the inclined rod 71 is fixedly connected to the bottom wall of the body 1, and the outer wall of the rod body at the lower end of the inclined rod 71 is fixedly sleeved with an annular block 72, and the outer circle diameter of the annular block 72 is slightly larger than the rod body diameter at the lower end of the inclined rod 71, ensuring that the lower end of the inclined rod 71 can always be in the annular groove 73 and move stably inside the annular groove 73.

[0032] The inner diameter of the annular groove 73 is slightly larger than the inner diameter of the circular groove 5 , and the depth of the annular groove 73 is the same as the depth of the circular groove 5 .

During the rotation of the long rod 82, the long rod 82 moves linearly synchronously, so that the end of the long rod 82 originally matched with the limit slot 84 moves, and the end of the long rod 82 moves out of the limit slot 84 reserved inside the circular bottom plate 3. When the long rod 82 moves linearly, the end of the long rod 82 is completely After completely moving out of the limit slot 84 and the circular slot 5, the circular base plate 3 can be rotated at this time. The circular base plate 3 rotates in the circular slot 5, thereby driving the angle of the entire magnetic levitation centrifugal chiller body 1 fixedly connected to the circular base plate 3 to change. At the same time, during the rotation of the body 1, the upper end of the inclined rod 71 fixedly connected to the two side walls of the magnetic levitation centrifugal chiller body 1 and the annular block 72 fixedly sleeved at the lower end of the inclined rod 71 move in the annular slide groove 73 reserved inside the base 4 as the body 1 rotates, thereby ensuring the stability of the angle adjustment of the body 1 and facilitating subsequent installation operations.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
