The LCD screen automatic lift is to store the computer LCD monitor in the table when it is not in use. When the display screen needs to be used, the lift hidden inside the conference table lifts the display screen from the bottom of the meeting to the surface of the table; when the display screen is not in use , the lift automatically descends, the display screen is hidden inside the conference table, the product has the characteristics of anti-theft, dust-proof; keeping 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 LCD screen lifter:
The first generation: chain drive structure, its disadvantages are unstable lifting, more oil pollution, loud noise, usually need to refuel, when adjusting the elevation angle, use a low-power DC motor, overload use, the motor is easy to burn out, and the repair rate is high. The system drive is completed by three motors. Compared with other lifters, the failure rate is the highest. (The panel has carbon steel and stainless steel)
Second generation: rack drive mechanism, its disadvantage is that there is a lot of oil pollution, after the lubricating oil is used up, the noise is large, usually need to be refueled, long-term use, nylon bushing is easy to wear, easy to produce gaps, and crawling occurs when falling , When adjusting the elevation angle, use a low-power DC motor, overload the use, the motor is easy to burn out; the repair rate is high, and the service life is short. Most parts need to be replaced after three years. The system function is completed by two motors. Compared with other lifters, the failure rate is higher. (The panel has carbon steel and stainless steel)
The third generation: round rod bearing transmission. Smooth transmission, no oil, no noise, no need to refuel, automatic elevation after rising, in line with ergonomic principles. The system is completed by a motor. The failure rate is low. (The panel has carbon steel and stainless steel)
The fourth generation: steel ball track structure, Beijing synchronous belt drive. Smooth transmission, no oil pollution, no noise, no need to refuel for long-term use, automatic elevation after rising, in line with ergonomic principles. The system is operated by a motor. Failure Lower rate. (Panels are available in carbon steel and stainless steel)
The fifth generation: the linear guide and the linear bearing are matched, and the low-speed micro-motor is used as the drive; the panel is extruded and stretched by an aluminum alloy profile die, and then precision-processed by a CNC milling machine and then drawn and oxidized; all linkage structures All imported high-precision bearings are used; the running noise of the whole machine has passed the inspection of national authoritative departments and fully meets international standards; the circuit part adopts high-reliability intelligent digital synchronous positioning and identification processing technology, with multiple protection functions; self-judgment and self-repair It adopts a communication interface circuit with high anti-interference ability to ensure the reliability of communication; the control mode is RS232/RS485, RF remote control and manual control, which can be easily connected with computers, remote control systems or various remote control equipment. (such as "CRESTRON, AMX" and other central control systems), it is convenient to realize individual control, group control and centralized control, and users can easily complete the demonstration process. This kind of lifter is the most advanced transmission mode of LCD screen lifter in China.
