A transparent mobile screen

Abstract

The invention discloses a transparent mobile screen. Sleeves are fixedly connected to the upper part and the lower part of the edge of each mobile screen body, and telescopic rods are sleeved with thesleeves. The end parts of the telescopic rods are fixedly connected with the inner walls of a frame body. The two sides of the lower end of each mobile screen body are fixedly connected with a threaded lantern ring and a support separately. The lower ends of the supports are rotationally connected with idler wheels, and the lower portions of the idler wheels are attached to guide grooves which are fixedly connected with the bottom face of the frame body. A two-way screw rod is connected in each threaded lantern ring in a threaded mode. The two ends of each two-way screw rod are rotationally connected with the lower inner wall of the frame body through bearings. A servo motor is arranged at the bottom of the frame body, and the right end of the servo motor is rotationally connected with adrive shaft. According to the mobile screen, the rotating drive shaft drives the two-way screw rods through transmission belts to rotate accordingly, the two-way screw rods drive the threaded lanternrings to drive the mobile screen bodies to move left and right, and thus the separation and combination functions of the whole screen are achieved due to left-right movement of the mobile screen bodies; and piston rods are driven to extend or retract by controlling the pressure intensity of oil in hydraulic cylinders, the piston rods extend or retract horizontally drive swing rods to swing throughconnection rods, and then moving wheels are driven to swing accordingly.

Description

technical field [0001] The invention relates to a screen device, in particular to a transparent mobile screen. Background technique [0002] The display screen is a screen composed of several combinable and spliced ​​display units or unit display boards or unit display cabinets, plus a set of appropriate controllers, main control boards or control systems. Therefore, display boards or unit boxes of various specifications can be combined with controllers of different control technologies to form many kinds of LED displays to meet the needs of different environments and different display requirements. With the ever-changing needs, mobile screens came into being. [0003] At present, most of the existing mobile screens have the problem that each sub-screen cannot move synchronously. The transmission accuracy is not high, which leads to the separation and splicing of the mobile screen. Moreover, the existing mobile screens generally have problems of stability and inconvenient m...

Problems solved by technology

[0003] At present, most of the existing mobile screens have the problem that each sub-screen cannot move synchronously. The transmission accuracy is not high, which leads to the separation and splicing of the mobile screen. Moreover, the existing mobile screens generally have problems of stability and inconvenient movement, which need to be moved and fixed. Need to use other auxiliary tools to complete, very inconvenient
