An adjustable projector support device using the principle of ratchet positioning

Abstract

The invention relates to the technical field of computer output equipment, and discloses an adjustable projector support device utilizing the principle of ratchet positioning, including a base, the top of which is rotatably connected to a rotating platform, and the inside of the rotating platform is flexibly connected to an adjustable The outside of the adjusting rod is movably connected with a flat gear, and the bottom of the flat gear is meshed with a flat tooth ring. The outside of the adjusting rod is movably connected with a fixed rod, and the outside of the fixed rod is fixedly connected with a Bevel gear, the external sleeve of the adjustment rod is connected with a worm, and the external meshing connection of the worm is connected with a ratchet ring gear, through the cooperation of the adjustment rod, the horizontal gear, the flat tooth ring, the fixed rod and the bevel gear, so as to achieve the adjustment The rotating table rotates on the top of the base to achieve the effect of adjusting the horizontal angle of the projector, and the operation is simple and the adjustment is convenient, which greatly reduces the trouble of adjusting the level of the projector, thereby improving the use effect of the device.

Description

technical field [0001] The invention relates to the technical field of computer output equipment, in particular to an adjustable projector support device utilizing the ratchet positioning principle. Background technique [0002] The output device is the terminal device of the computer hardware system, which is used to receive the output display, printing, sound, and control the operation of the peripheral equipment of the computer data. , Common output devices include monitors, printers, plotters, projectors, magnetic recording devices, etc. Among them, the projector, also known as the projector, is a device that can project images or videos onto the screen. computer connection. [0003] When the projector is in use, it is often necessary to adjust the vertical inclination 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 inclination ang...

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
