The three-dimensional LED display screen module on the market at present generally processes the polaroid into a strip shape, or processes into a block shape according to the size of the LED packaging size, and then installs the face mask, and the defect of the mode is that the visual angle is small, and the mounting wastes time and energy. Or the polaroid is processed into concave and convex shapes according to the dot spacing, and the mode is only suitable for display modules with large spacing. For the LED display module with small spacing, no enough gap exists between two LEDs to enable the polaroid to be recessed, and the development of the small-spacing LED display screen industry cannot be kept up with. Even if the strip-shaped polarizer with the connecting part is cut, the patent document of application No. 201721491987.7 discloses a three-dimensional LED display screen module, which is searched because of narrow processing size, soft material and time-consuming pasting. The novel polaroid is arranged on the LED display screen module with the cured resin layer, a series of small holes are punched at equal intervals on the polaroid according to the size of the distance between the display screens and the size of the LED light-emitting surface, and the polaroids are processed into NXN type polaroids with a sheet structure as a unit. Therefore, when the polaroid is adhered, the polaroids can be adhered in a whole piece, the defects of time and labor waste caused by the fact that the polaroids are adhered one by one and adhered one by one in the prior art are overcome, and the production efficiency is greatly improved.

However, the three-dimensional LED display screen module is time-consuming and labor-consuming to install, and is inconvenient to disassemble and maintain when in failure, so that the improvement mode of adding the lifting structure into the three-dimensional LED display screen base is provided, and the problem is solved.

To the various not enough that exist among the prior art, the utility model aims at providing a three-dimensional LED display screen can effectual problem among the solution background art.

The utility model discloses a three-dimensional LED display screen, which comprises a base, a lifting component and an LED display screen; the base is provided with a lifting upright post, a lifting cavity is arranged in the lifting upright post, and the side wall of the lifting upright post is provided with a strip-shaped opening for communicating the outside with the lifting cavity; the lifting assembly comprises a motor, a screw rod, a lifting block and a connecting frame; the motor is arranged below the lifting cavity in the base; the screw is arranged in the lifting cavity and is coaxially connected with a rotating shaft of the motor; the lifting block is matched with the screw thread on the screw in a lifting way; the connecting frame is fixedly connected with the lifting block through a strip-shaped opening outside the lifting upright post; the LED display screen is fixedly connected with the connecting frame through bolts.

Preferably, the height of the strip-shaped opening is not more than one and a half times of the height of the lifting upright post.

Preferably, the height of the lifting column is not more than twice the width of the base.

Preferably, a clamping groove frame is arranged on the base corresponding to the LED display screen and used for fixing the bottom of the LED display screen during screen unloading.

Preferably, the base is further provided with a switch button for controlling the on-off of the motor.

The utility model has the advantages that: through the lifting upright post and the lifting assembly arranged on the base, the lifting of the three-dimensional LED display screen can be realized, the assembly and disassembly maintenance of the three-dimensional LED display screen is facilitated, and the probability of falling damage of the three-dimensional LED display screen during the assembly and disassembly maintenance is greatly reduced.
