DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Embodiment: A liftable and rotatable seat frame, such as Figure 1-3As shown, it includes a seat 1, a fixedly connected limit rod 2 is provided at the bottom of the seat 1, a support frame 201 is slidably sleeved on the limit rod 2, the support frame 201 is provided with three support legs, a drive motor 3 is installed at the middle part below the support frame 201, the output shaft of the drive motor 3 is connected with a threaded rod, the threaded rod is passed through the limit rod 2, a limit frame 4 is installed at the bottom of the seat 1, and the limit frame 4 is slidably connected to the support frame 201; the upper end of the limit frame 4 is fixedly connected to the bottom of the seat 1, and a plurality of connecting rods are provided at the lower end of the limit frame 4, and the connecting rods pass through the support frame 201.

[0023] When in use, a person sits on the seat 1, and the support frame 201 assists the limit rod 2 to support the seat 1. When the height needs to be adjusted, the drive motor 3 is started to drive the threaded rod to rotate, thereby driving the limit rod 2 to move up and down, and the limit rod 2 slides on the support frame 201, and the limit frame 4 slides on the support frame 201 to realize the lifting and lowering of the seat 1. The limit frame 4 can effectively limit the support legs of the support frame during the lifting process to prevent excessive height adjustment or displacement and shaking. When the appropriate height is adjusted, the drive motor 3 is turned off, which is convenient for people to adjust the height of the seat 1 according to their needs.
