Anti-falling accurate lifting equipment for multimedia projector

Abstract

The invention relates to the technical field of multimedia, and discloses anti-falling accurate lifting equipment for a multimedia projector. The equipment comprises a whole equipment shell, wherein an inflator pump is movably connected to an air bag; an oil tank is movably connected to the bottom end of a hydraulic lifting rod; a pressurizing pedal is movably connected to the oil tank; an electromagnetic oil drain valve is movably connected to the pressurizing pedal; a supporting plate is fixedly connected to the upper end of the hydraulic lifting rod; L-shaped supporting hooks are fixedly connected to the left end and the right end of the supporting plate; hammer-shaped threaded sliding rods are fixedly connected to the bottom ends of the L-shaped supporting hooks; and brush threaded sleeves are movably connected to the hammer-shaped threaded sliding rods. The hydraulic lifting rod is connected to the oil tank through a main oil pipe, the oil tank is connected to the pressurizing pedal through a one-way valve oil conveying pipe, oil is sucked into the bottom end of the interior of the pressurizing pedal through the one-way valve oil conveying pipe, the interior is pressurized through the pressurizing pedal, the oil can be conveyed to the main oil pipe through the one-way valve oil conveying pipe connected to the upper end of the pressurizing pedal, and the oil is conveyed into the bottom end cavity of the hydraulic lifting rod through the main oil pipe to jack up the supporting plate.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to an anti-drop precision lifting device for a multimedia projector. Background technique [0002] Multimedia technology is to use computers to digitize media information such as text materials, video materials, audio and video, and integrate them into interactive interfaces, so that computers can interactively display different media forms. In modern people's lives, in addition to Schools, as well as many companies, museums and even homes cannot do without projectors. [0003] Existing projectors are erected with a support frame when they are in use, and they need to be manually adjusted to an appropriate height when they are erected. In both cases, the operation is cumbersome and takes a long time, and the stability of some projector lifting equipment is not good. It is easy to damage the projector when colliding. At present, there are a few automatic multimedia projector lif...
