Problems solved by technology

[0003] Projectors are generally installed on the top of buildings to carry out work, and they need a hoisting mechanism to install them. When installing the projector in the existing hoisting mechanism, they need to be connected by four bolts. The speed of screwing each bolt is relatively slow. Easy to install and disassemble the projector

Abstract

The invention discloses a projector hoisting mechanism convenient to install and remove for electrified education equipment. The projector hoisting mechanism comprises a hoisting base, a hoisting column, an installation shell, hoisting claws, a third motor, a rotating shaft, multiple bevel gears, an installation shaft, a sleeve, a connection bolt, a first motor, a second motor, a first thread rod,a second thread rod, a movable base and a steering device. The steering device comprises a stepping motor, a gear and an outer gear ring. The projector hoisting mechanism has the beneficial effects that since the third motor, the rotating shaft, the multiple bevel gears, the installation shaft, the sleeve and connection bolts are arranged, the connection bolts on the four hoisting claws stretch into thread installation holes in the top of a projector at the same time along with rotation, operation is easy, convenient and fast, and the projector can be rapidly installed and removed; by means of the first motor, the second motor, the first thread rod, the second thread rod, a movable base and the hoisting base, the height and horizontal position of a hoisting device can be adjusted; and since the steering device is arranged, the projection angle of the projector can be adjusted.

Description

technical field [0001] The invention relates to the technical field of projector hoisting, in particular to a projector hoisting mechanism for audio-visual equipment that is convenient for installation and disassembly. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal. Projectors are currently widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. [0003] Projectors are generally installed on the top of buildings to carry out work, and they need a hoisting mechanism to install them. When installing the projector in the existing hoisting mechanism, they need to be connected by four bolts. The speed of screwing each bolt is relatively slow. Easy to install...
