Abstract

The invention relates to the technical field of projectors, and discloses a projector capable of freely adjusting an angle. The projector comprises a box body, an adjusting shaft is movably connected to the rear side in the box body, the left end of the adjusting shaft is in threaded connection with an adjusting knob outside the box body, and the left end of the adjusting shaft is fixedly connected with a second-level adjusting display structure on the right side of the adjusting knob. The left end of the adjusting shaft is fixedly connected with a third-level adjusting display structure on the right side of the second-level adjusting display structure, a first-level adjusting gear is fixedly installed in the middle of the adjusting shaft, a second-level adjusting gear is fixedly installed in the middle of the adjusting shaft on the left side of the first-level adjusting gear, and a third-level adjusting gear is fixedly installed in the middle of the adjusting shaft on the right side of the first-level adjusting gear. According to the projector capable of freely adjusting the angle, the adjusting knob is rotated to drive the adjusting shaft to rotate, then the adjusting gear is driven to rotate, the adjusting gear drives a fixing gear to rotate and drives a rack to move, the rack drives a third hinge base to move, the third hinge base jacks up the front end of an installation base, and angle adjustment of the projector is achieved.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a projector whose angle can be adjusted freely. Background technique [0002] A projector, also known as a projector, is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It is a device that can project images or videos onto a screen. The interface is connected with the computer, VCD, DVD, BD, game console, DV, etc. to play the corresponding video signal. The projector is widely used in homes, offices, schools and entertainment places. [0003] As a meeting and teaching tool, projectors are widely used at present, and are usually placed directly on the table. However, this installation method has a fixed position and cannot be moved. It can only be fixed in one direction for projection. If you replace other models The projector cannot be used if you want to change the projection angle. During the use of the pr...
