Abstract
The utility model relates to a front maintaining back-projecting wide screen display unit device, which comprises a screen, a front maintenance door, an outer casing, a fixed bracket, an adjusting device, a projecting source, a primary transmitting mirror and a secondary transmitting mirror. The front side of a box body is formed by vertically connecting the screen and the maintenance door; the box body is formed by connecting the front side of the box body and the outer casing; the fixed bracket is arranged at the bottom of the box body; the adjusting device is arranged on the fixed bracket; the projecting source is arranged on the projecting device; and the primary transmitting mirror and the secondary transmitting mirror are arranged inside the box body, thereby forming an imaging optical path. Compared with the prior art, the utility model changes a projecting angle formed by transmitting optical information; due to the adoption of secondary reflection, the box body is reduced by above 160 millimeter in thickness compared with the thickness of a similar box body, and has fine structure; a larger space is not required to be reserved on the rear side as well as the left and the right sides for a display wall composed of the box body capable of being modulated and maintained from the front side, and the occupied space of the display wall can be reduced by three fourths. The screen display unit device is particularly suitable for compact sites.
Description
Technical field
The utility model relates to back projection display apparatus, particularly preceding maintenance back projection wide screen display unit device.
Background technology
The modular construction that the back casting large screen display wall is made up of N * M display unit box, the image that it shows is that one or several picture is divided into N * M little picture through digital technology, is sent to through digital technology and pieces together a big picture on the display wall.So, require that each body structure is light and handy, load-bearing is firm, easy for installation, interchangeability good, also requires cabling rationally noiseless simultaneously, dustproof lucifuge is ventilated.At present, the casing that is combined into display wall is to adopt back debugging structure, in the back of display wall (being not less than the space of 1000mm) and and arranged on left and right sides (respectively being not less than the space of 1000mm) all need reserve than large space, be convenient to the commissioning staff and enter and work; Its casing is made of the seal cavity of optical information propagation ducts and the debug space of rear lower, adopts plug-in display screen, so casing is thicker; And need two people to cooperate debugging, and a people is in preceding observation image transfer information, and a people debugs at laggard line operate.This structure, light are settled the display wall casing to add debug space and have just been taken the site space of distance more than at least 2 meters, have reduced the space of display wall front relatively, operating personnel visual field optic angle is little, observe inconvenience, waste time and energy and weak effect, more influence it in less rig-site utilization.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of casing thin preceding maintenance back projection wide screen display unit device for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: preceding maintenance back projection wide screen display unit device, it is characterized in that, this device comprises screen, preceding maintenance door, shell, fixed mount, adjustment equipment, the projection source, a transmitting mirror, the Secondary Emission mirror, described screen and preceding maintenance door connect and compose the casing front up and down, this casing is positive to connect and compose casing with shell, described fixed mount is located at bottom half, described adjustment equipment is located on the fixed mount, described projection source is located on the adjustment equipment, a described transmitting mirror, the Secondary Emission mirror is located at box house, constitutes imaging optical path.
Described shell comprises left plate, right plate, top board, back plate, base plate.
Described fixed mount is located on the base plate.
Maintenance door comprises door, door lock before described.
Described left plate, right plate include trough.
Described top board comprises cable hole.
Described back plate is provided with fresh air inlet, air outlet opening.
Compared with prior art, the utility model has changed optical information and has propagated projectional angle, adopts secondary reflection, so but than casing thickness attenuate of the same type more than 160 millimeters, the structure exquisiteness is small and exquisite; The display wall that the casing that simultaneously can debug, safeguard from the front is formed does not need to reach in the back left and right side and reserves than large space, and its space of occupying can reduce 3/4ths, is specially adapted to compact scene.
