The invention discloses a back projection reflecting system fixing device, wherein the fixing device comprises a reflector fixing bracket and a projector fixing bracket cooperatively used with the reflector fixing bracket, the reflector fixing bracket comprises a first base, a telescopic device installed on the base, a reflector fixing device connected with the telescopic device and an adjustablereflector installed on the reflector fixing device, the back surface of the reflector is connected with a connecting device, and the connecting device is connected with the reflector fixing device through a movable hinge; and the projector fixing bracket comprises a second base and an adjusting device installed on the second base for adjusting the height and angle of the projector. The back projection reflecting system fixing device disclosed by the invention is lapped by aluminum alloy sections, so that the product outline is beautiful and is free from rust; the thermal conductivity of the aluminum alloy is higher than that of iron, so that the aluminum alloy sections are selected to facilitate the radiating the projector bracket; the installation is convenient, the production period is shortened and the mounting difficulty is reduced; and the suspension design can theoretically utilize the actual area of the reflector in a hundred percent.
Description
technical field [0001] The invention relates to a projector fixing device, in particular to a rear projection reflection system fixing device. Background technique [0002] The existing common reflective system devices are built with iron square pipes, and the iron square pipes are connected by welding. The reflector and the projector are adjusted to the required angle by fixed axis rotation. It should be pointed out that this method requires a piece of rotationally restrained iron sheet metal washed with arc grooves. The sheet metal requires high precision and is difficult to process. The sheet metal is also connected with the square tube by welding, and combined by nesting the inner and outer square tubes. The outer square tube is drilled, supplemented by bolt constraints and the distance of the inner tube, and at the same time, the friction between the bolt and the inner square tube is used to fix the inner square tube to the required height. [0003] The original pro...
