[0002] Liquid crystal screen is a display technology widely used in various electronic devices. It is composed of liquid crystal materials. The transmission of light is controlled by adjusting the direction of liquid crystal molecules to display images and texts. LCD screen laboratory power control usually refers to the equipment used to control the power supply of LCD screens in laboratories.

[0003] The existing touch-operated LCD screen laboratory power control directly installs the LCD screen connected to the circuit board in the laboratory, and then controls the power through the LCD screen. Since the LCD screen is fragile, the LCD screen is easily scratched or damaged when exposed on the surface, which increases the maintenance cost of the equipment and is relatively inconvenient.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.

[0021] A touch-operated LCD screen laboratory power control device, such as Figure 1-Figure 3As shown, it includes a shell 1, a circuit board 2, connecting wires 3, a connecting port 4, a fixed rotating frame 5, a display screen 6 and a protective mechanism 7. Eleven ventilation grooves are provided on the left side of the shell 1 for ventilation. The circuit board 2 is connected inside the shell 1. The connecting wires 3 are connected to the lower left side of the shell 1. The connecting wires 3 are connected to the circuit board 2. Two connecting ports 4 are provided on the lower side of the shell 1 and three connecting ports 4 are also provided on the right side of the shell 1. Two upper and lower fixed rotating frames 5 are rotatably connected to the rear sides of the left and right parts of the shell 1. The circuit board 2 is connected to the display screen 6, and the display screen 6 is located in the shell 1. The shell 1 is provided with a protective mechanism 7 capable of protecting the display screen 6.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the protection mechanism 7 includes a fixed bracket 70, a protection cover 71 and a torsion spring 72. The fixed bracket 70 is connected to the upper side of the shell 1, and the protection cover 71 is rotatably connected to the fixed bracket 70. The protection cover 71 is made of tempered glass and has high scratch resistance and impact resistance. The protection cover 71 can be snapped onto the shell 1, and torsion springs 72 are connected between the left and right sides of the lower part of the protection cover 71 and the fixed bracket 70.

[0023] like Figure 1 and Figure 5 As shown, a cleaning mechanism 8 is also included, and the cleaning mechanism 8 includes a connecting movable frame 80 and a cleaning roller 81. The connecting movable frame 80 is slidably connected to the protective cover 71, and the connecting movable frame 80 is rotatably connected to the cleaning roller 81. The cleaning roller 81 is made of silicone and has good high temperature resistance and chemical corrosion resistance. The softness and adhesion of silicone are helpful in removing fine dust. The cleaning roller 81 is in contact with the inner side of the protective cover 71.

[0024] When using the device, first rotate the fixed rotating frame 5 and install the fixed rotating frame 5 in the power control area of ​​the laboratory so that the shell 1 is fixed on the wall of the laboratory. When power control is needed, the connecting wire 3 can be connected to the socket to power on the circuit board 2. After power on, power control is performed through the display screen 6. During the power-on process of the display screen 6, air is ventilated through the air vent on the shell 1, and the connection port 4 is connected to other external devices. When the device needs to be disassembled and transferred, the fixed rotating frame 5 can be removed, and then the fixed rotating frame 5 can be rotated to disassemble and transfer the device. When the display screen 6 is no longer needed, the protective cover 71 can be put on the fixed rotating frame 5. The fixed bracket 70 is rotated to deform the torsion spring 72, so that the protective cover 71 can be snapped into the shell 1, so that the display screen 6 can be protected to prevent the display screen 6 from being scratched and damaged, thereby reducing the equipment maintenance cost. When the display screen 6 needs to be used, the protective cover 71 is rotated, and the protective cover 71 is no longer in contact with the shell 1, so that the torsion spring 72 is restored. When the protective cover 71 is used for a long time, it can be held by the connecting movable bracket 80 to move, driving the cleaning roller 81 to rotate, and the cleaning roller 81 contacts the protective cover 71, so that the dust on the protective cover 71 can be cleaned to prevent dust from penetrating into the equipment, thereby extending the service life of the device.
