[0017] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0018] Please refer to Figures 1 to 3 A lifting display screen includes a base 10, an electric push rod 20 is vertically provided on the base 10, a slide tube 21 is sleeved on the electric push rod 20, the bottom end of the slide tube 21 is fixedly connected to the base 10, a lifting sleeve 30 is slidably sleeved on the peripheral wall of the slide tube 21, the top of the electric push rod 20 is connected to the top of the lifting sleeve 30, a screen body 40 is provided on the lifting sleeve 30, the back of the screen body 40 is fixedly connected to the outer peripheral wall of the lifting sleeve 30, two guide tubes 50 are vertically provided on the base 10, the two guide tubes 50 are symmetrically distributed on both sides of the electric push rod 20, a sliding assembly is provided on the back of the screen body 40 at a position corresponding to the guide tube 50, and the sliding assembly is slidably connected to the guide tube 50.

[0019] In the above scheme, the screen body 40 is installed on the lifting sleeve 30, and the lifting sleeve 30 is slidably sleeved on the slide tube 21. When the electric push rod 20 is started, the electric push rod 20 can drive the lifting sleeve to slide up and down along the slide tube 21, thereby adjusting the height of the screen body 40, which is suitable for different scenes and meets different usage requirements, and is easy to operate. In addition, the screen body 40 is slidably connected to the guide tube 50 through the sliding assembly during the lifting process, thereby improving the stability during the movement process, and the guide tube 50 also serves as a limit for the screen body 40.

[0020] Please refer to Figure 3 The top of the inner cavity of the lifting sleeve 30 is provided with an inner tube 31, which is sleeved on the upper part of the electric push rod, and the inner tube 31 is fixedly connected to the electric push rod 20. The lifting sleeve 30 is fixedly connected to the electric push rod 20 through the inner tube 31, so that the electric push rod 20 can drive the lifting sleeve 30 to move up and down.

[0021] Please refer to Figure 4 The sliding assembly includes a connecting block 41, one end of which is fixedly connected to the back of the screen body 40, a slide groove 51 is vertically opened on the side wall of the guide tube 50, and the other end of the connecting block 41 passes through the slide groove 51, and two pulleys 42 are rotatably provided at the other end of the connecting block 41, and the pulleys 42 abut against the inner wall of the guide tube 50. In the process of the screen body 40 moving up and down, the pulley 42 rolls along the inner wall of the guide tube 50, the rolling friction is small, and the movement is smooth and stable. Furthermore, a limiting cover plate 52 is provided at the top of the guide tube 50 to prevent the pulley 42 from sliding out of the guide tube 50, causing the screen body 40 to detach, thereby protecting the screen body 40. In addition, in the present embodiment, one end of the connecting block 41 is detachably fixedly connected to the back of the screen body 40 by screws, and the connection is stable and easy to disassemble and assemble.
