Adjustable projector supporting device using principle of ratchet positioning

Abstract

The invention relates to the technical field of computer output equipment, and discloses an adjustable projector supporting device using the principle of ratchet positioning. The adjustable projectorsupporting device using the principle of ratchet positioning comprises a base, the top of the base is rotatably connected with a rotating table, and an adjusting rod is movably connected into the rotating table; the outer part of the adjusting rod is movably connected with a flat-turning gear, the bottom of the flat-turning gear is in meshing connection with a flat tooth ring, the outside of the adjusting rod is movably connected with a fixed rod, the outside of the fixed rod is fixedly connected with a bevel gear, a worm is connected to the outer part of the adjusting rod in a sleeving mode,and the outer part of the worm is meshing connection with a ratchet gear. Through the coordinated use of the adjusting rod, the flat-turning gear, the flat tooth ring, the fixed rod and the bevel gear, the effect of adjusting rotating of the rotating table at the top of the base is achieved, the effect of adjusting the horizontal angle of a projector is achieved, the operation is simple, the adjustment is convenient, the trouble of horizontal adjustment of the projector is greatly reduced, and the use effect of the device is improved.

AI Technical Summary

Problems solved by technology

[0003] When the projector is used, it is often necessary to adjust the vertical tilt angle and horizontal rotation angle of the projector according to the actual situation. Since the projector is generally fixedly connected to the support frame, when adjusting the vertical tilt angle, the existing adjustment method is usually by adjusting the projector support. The height of the four support rods at the bottom of the frame makes the four support rods present a certain height difference to realize the vertical tilt adjustment of the projector. However, this adjustment method is troublesome to operate, time-consuming and laborious, and the adjustment efficiency is low, and it is easy to make the projector during adjustment. There is a certain inclination, which affects the effect of projection; when adjusting the horizontal angle, the projector and the support frame are often fixedly connected, which leads to the need to rotate the entire support frame when adjusting the horizontal angle. The operation is very troublesome, resulting in the existing projector support Poor use of the device
