Junnan Audiovisual is a manufacturer that designs, develops, researches and produces audiovisual audio equipment. For more than ten years, our factory has been producing audio-visual impact equipment, projector lifter, LCD TV lifter, microphone lifter, desktop flipper, LCD flipper, flat-panel TV trolley, cabinet trolley, metal instrument cart, projector electric There are various types and specifications of hangers.

The automatic LCD screen elevator produced by Junnan Audiovisual is to put the computer LCD monitor in the table when it is not in use. When the display screen is needed, the elevator hidden inside the conference table lifts the display screen from the bottom of the meeting to the surface of the table; when the display is not in use When the screen is turned on, the lifter automatically descends, and the display screen is hidden inside the conference table. The product is anti-theft and dust-proof; it keeps the surface of the table flat and beautiful.

At present, it is widely used in banks, industrial and commercial desks, hospital podiums, government agencies, school multimedia classroom podiums, etc.

The development history of the LCD lifter:

First generation:

The chain transmission structure has the disadvantages of unstable lifting, heavy oil pollution and high noise. It usually needs to be refueled. When the elevation angle is adjusted, a low-power DC motor is used. It is overloaded and the motor is easy to burn out. The repair rate is high. The system drive is driven by three motors. Complete. Compared with other lifters, the failure rate is the highest. (The panel has carbon steel and stainless steel) LCD TV lifter

Second generation:

The disadvantage of the rack drive mechanism is that there is a lot of oil pollution. After the lubricating oil is used up, the noise is loud. It must be refueled at ordinary times. After long-term use, the nylon sleeve is easy to wear and gaps. It will crawl when falling. Power DC motor, overloaded use, the motor is easy to burn out; high repair rate, short life. After three years, most parts need to be replaced. The system function is completed by two motors. Compared with other elevators, the failure rate is higher. (The panel has carbon steel and stainless steel, and the aluminum alloy panel: non-integrated panel does not have a strong impact Screw fixation)

Third Generation:

Steel ball track structure, synchronous belt transmission. Smooth transmission, no oil pollution, no noise, no need to refuel for long-term use, automatic elevation angle after rising, in line with ergonomics. The system is moved by a motor. (The panel is made of carbon steel and stainless steel)

Fourth Generation:

Round rod bearing transmission (steel wire pulling). Smooth transmission, automatic elevation angle after rising, in line with ergonomics. The system is completed by a motor. The failure rate is low, but the motor failure cannot be repaired. (Frosted panel, stainless steel, Aluminum alloy one-piece panel)

Fifth Generation:

The linear guide rail cooperates with the synchronous belt drive, and the panel is formed with a brushed aluminum alloy panel; the deflection angle of the display is pulled by a spring or determined by a travel switch, and the deflection angle of the display will change over time. (Aluminum alloy one-piece molding panel)

Sixth generation:

Driven on the mold module by the positioning bearing positioning timing belt and the industrial screw rod, the aluminum alloy drawing panel is formed in one piece, and the infrared grating switch is used to accurately determine the deflection angle of the display.
