This article is mainly about the related introduction of the LCD screen lifter, and focuses on the detailed explanation of the working principle of the LCD screen lifter and the maintenance of common faults.
LCD screen lifterLCD screen lifter, when you need to use the display screen, the lift hidden inside the conference table lifts the display screen from below the meeting to the surface of the table; when the display screen is not used, the lift automatically descends, and the display screen is hidden inside the conference table, preventing theft, Dustproof; keep the surface of the table flat and beautiful.
When a newly installed LCD screen lifter or an LCD screen lifter that has been used for a period of time fails, you need to understand the fault before you can operate it when you have to repair it yourself, otherwise it will damage the LCD screen lifter. The following is Maintenance and elimination of common faults:
If the LCD screen lifter has no response, nothing moves:
1. Check whether the power supply is plugged in, whether the power cord is properly connected, whether the voltage is normal, if it is not connected, then fix it; if there is no power, check whether the power supply line is normal.
2. If there is no problem with the voltage of the power supply line, you need to check the button connection, check whether the motor connection line is off, and then check whether the fuse is blown, and whether the travel switch wiring of the upper terminal and the lower terminal is off.
3. When the lifting frame is at the upper terminal and the upper terminal travel switch is pressed, the lifting frame cannot go up; when the lifting frame is at the lower terminal, the lower terminal travel switch is pressed and the lifting frame cannot go down. This is a normal phenomenon. Only need to manually press the switch.
4. If none of the above is the case, pressing the up and down buttons will not work, but there is a weak vibration sound. At this time, you have to check whether the capacitor is broken or short-circuited, and then check whether the connection is open. And fall off. When the motor heats up very seriously, it is necessary to cut off the power immediately to prevent the motor from being burned out.
If the LCD screen lifter can't move up or down, but loud noise is emitted from the cabinet:
One. Check whether the transmission chain is disconnected or broken;
two. Check whether the meshing between the aluminum guide rail and the sprocket is misaligned;
three. Check whether the restraining screw between the shaft and the sprocket is loose, so that the shaft cannot rotate with the sprocket, causing the four guide rails to run out of sync;
The above is about the common troubleshooting methods of LCD screen lifters. As long as it is not a big problem, we can solve it by ourselves. However, if we encounter more serious problems, we need professionals to repair it. Operate blindly by yourself to avoid irreparable losses.

Principle and structure of LCD screen lifterProduct features of LCD screen lifter:
1. Flexible use, stable performance and good shock resistance;
2. Automatic opening and closing decorative panels are beautiful and generous;
3. Stainless steel panel, Mosha carbon steel panel and many other panels are available;
4. Integrating manual control and remote control, multiple control methods are more flexible to use;
5. Rack and pinion transmission, sleeve positioning, more stable operation and long service life;
6. Advanced photoelectric positioning system can achieve precise positioning;
7. A variety of circuit protection systems, when the LCD screen drops, the control panel automatically cuts off its power supply, which can safely protect the display;
8. A variety of data line interfaces can easily provide signals for the display;
9. The cabinet is compact, light weight, and more convenient to install.
way to control:
1. Manual control: separate control according to the small manual control panel set on the desktop.
2. Remote control: It is controlled by a wireless remote control, which can program six kinds of programs.
Installation requirements:
1. Stabilize the lifter in the conference table, and support the bottom of the LCD lifter to prevent the internal screws from loosening due to long-term use.
2. Fix the monitor firmly on the connecting plate, and the four screws should be evenly stressed.
Use environment requirements:
1. The temperature is between -10 degrees and +40 degrees;
2. The relative humidity is not more than 95% indoor;
3. The use environment does not contain organic solvent mist and corrosive gas;
4. Avoid intense vibration and collision.
