Combined projection device with super large screen

Abstract

A combined projection device with a super large screen comprises a screen. A combined projector frame structure formed by splicing a plurality of cubic frames is arranged in the rear of the screen. Each cubic frame is composed of multiple section bars and multiple connectors combined together. The columns, cross beams and longitudinal beams of the cubic frames are made of section bars of the samestructure. Each section bar is provided with T slots on the four side walls thereof. Threaded holes are formed in the centers of the two end faces of the column section bars, the cross beam section bars and the longitudinal beam section bars. The column section bars, the cross beam section bars and the longitudinal beam section bars intersecting at the same corner of the cubic frames are fixedly connected by 3D corner connectors. Splicing connectors used for splicing and combining are installed at the four corners of the upper and lower end faces and at the four corners of the left and right end faces of each independent cubic frame. The bottom layer of the combined projector frame structure is a control device placement layer, and the cubic frames in the other layers are projector framesequipped with reflectors and projectors.

Description

technical field [0001] The invention relates to the field of large-screen projection, in particular to an ultra-large-screen combined projection device. Background technique [0002] With the advent of the information age, the rapid development of computer multimedia technology, the widespread application of network technology, the establishment of command and monitoring centers and network management centers, as well as the conduct of temporary meetings and technical lectures, all desire large-screen, multi-color, High-brightness, high-resolution display effects, while traditional CRT monitors are difficult to meet people's requirements in this regard. The large-screen projector technology developed rapidly in recent years has become an effective way to solve the problem of color large-screen display. The scope of application has been further expanded, and the market has become increasingly active due to the growth of demand. [0003] Large-screen projection is formed by s...

AI Technical Summary

Problems solved by technology

At present, a single projector on the market is assembled in a frame of a solid structure, which takes up a large space, which is not conducive to storage and transportation; when the frames of multiple projectors are spliced ​​and combined, adjacent The frame is fixed and connected by bolts, the efficiency of the splicing combination is low, and the accuracy of the splicing combination cannot be guaranteed, which reduces the display effect of the large-screen projection; Difficult to meet the needs of large-screen projection in various environments
