Laser projection focus adjuster and laser projector

Abstract

The invention discloses a laser projection focusing regulator and a laser projector, comprising: a first transmission gear, which is fixedly mounted on a lens base through a first transmission gear bracket; a base; and a second transmission gear, which passes through a first transmission gear bracket. A shaft support is fixedly installed on the base; a third transmission gear is fixedly installed on the base through the second shaft support and is connected with the focus adjuster of the laser projection TV through the rotating shaft of the second shaft support; transmission The two ends of the shaft are respectively connected with the second transmission gear and the third transmission gear; the first transmission gear meshes with the gear of the second transmission gear, and the focus adjuster of the laser projection TV is connected with the third transmission gear. The first transmission gear is formed with a fixing groove for fixing the focus adjustment handle of the lens. The present invention solves the problem that the current focus adjustment style is single, and at the same time expands the focus adjustment area that can be achieved.

Description

technical field [0001] The invention belongs to the technical field of laser projection television, and in particular relates to a laser projection focus adjuster and a laser projector. Background technique [0002] Laser projection TV is a new laser image reproduction technology, which makes full use of the advantages of laser itself. In the way of light propagation, laser light sources are fundamentally different from traditional incandescent lamps and halide lamps: ordinary incandescent lamps and halide lamps emit light in all directions, while lasers gather all the light in a parallel in the beam. In addition, laser projection TVs can express a larger range of colors than traditional projection TVs, providing clearer images. [0003] Although laser projection TV technology has achieved great technological development and innovation, the adjustment working surface and position of the focus adjuster of the ultra-short-focus laser projection TVs currently on the market ar...

Problems solved by technology

[0003] Although laser projection TV technology has achieved great technological development and innovation, the adjustment working surface and position of the focus adjuster of the ultra-short-focus laser projection TVs currently on the market are restricted by the working surface and position of the focus adjustment handle on the lens, that is, the focus The adjustment working surface of the adjuster is generally perpendicular to the optical axis, and its position is generally near the focus adjustment handle of the lens, so the appearance design of the whole machine is also restricted to a certain extent.
