Mounting base for ultra-short-focus laser projector

Abstract

The invention discloses a mounting base for an ultra-short-focus laser projector. The mounting base comprises an adjusting plate, a fixing plate, an ultra-short-focus laser projector body, a servo motor, a mounting plate, push rod motors, fixing blocks, telescopic springs, adjusting blocks, stop blocks, baffle, limiting springs, connecting rods, a connecting block, a sliding block and a threaded rod, wherein a placing groove is formed in the top of the adjusting plate, the fixing plate is arranged in the placing groove, and the fixing plate is slidably connected with the placing groove. According to the mounting base, through the arrangement of the limiting springs, limiting blocks move in limiting grooves and adjusting grooves, the limiting blocks extrude the adjusting blocks, the telescopic springs generate a reverse elastic force, the adjusting blocks push the limiting blocks in the changing position, the limiting blocks are released between the limiting blocks and the adjusting grooves, and the limiting blocks between the fixing plate and the adjusting plate are released according to the same principle. The structure is simple, the operation is convenient, the projector can bequickly installed and disassembled, the time is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a mounting base, in particular to a mounting base for an ultra-short-focus laser projector, and belongs to the technical field of projector installation and application. Background technique [0002] Laser projectors use laser beams to transmit images. The optical components of laser projectors are mainly composed of red, green and blue three-color light valves, beam combining X prisms, projection lenses and driving light valves. In laser projectors, there are red, green, and Blue three-color laser, the laser beam is expanded by corresponding optical elements and processing chips in the machine, and then transmitted to the X prism to integrate the three beams of laser light, and then the integrated laser light is transmitted to the projection screen by the projection objective lens to complete the whole process. A laser projector shows the process. [0003] The existing installation bases of ultra-short-focus laser projectors ...

Problems solved by technology

[0007] (2) How to drive the connecting block to move through the threaded rod, so that the connecting block drives the connecting rod to rotate. Since the length of the connecting rod remains unchanged, the connecting rod pushes the fixed plate to rotate, thereby adjusting the projection angle of the projector, to solve the problem in the prior art. The problem that the projection angle cannot be adjusted precisely
