Description

Technical Field

[0001] The utility model relates to the technical field of LCD liquid crystal screens, in particular to an LCD liquid crystal screen that is anti-static interference. Background Art

[0002] Liquid crystal display is a type of flat panel display technology used in a wide range of electronic devices. A typical LCD screen consists of multiple layers, including a layer of liquid crystal material sandwiched between two sheets of glass. LCD screens also usually include a backlight to provide a bright background.

[0003] When the existing LCD screen is in use, it is usually exposed in the installation area to display the picture. When it is not adapted to the external environment, it is easy to damage the LCD screen, which affects the service life of the LCD screen and increases the cost of using the LCD screen.

[0004] Therefore, an anti-static LCD screen has been developed to shield and protect the LCD screen, avoid exposure of the LCD screen, and improve the safety of the LCD screen. Summary of the invention

[0005] In order to overcome the shortcomings of the existing LCD screen, which is usually exposed in the installation area to display the picture when in use and is easily damaged by the external environment when it is not adapted, the utility model provides an anti-static interference LCD screen which can shield and protect the LCD screen, avoid the LCD screen from being exposed, and improve the safety of the LCD screen.

[0006] Technical solution: An anti-static interference LCD screen includes a mounting frame, a liquid crystal screen, a grounding wire, a fixing block and a shielding mechanism. The mounting frame is connected to multiple groups of fixing blocks, each group is composed of four fixing blocks, each group of fixing blocks is connected to a liquid crystal screen, and multiple liquid crystal screens are connected to the mounting frame. The liquid crystal screens can be spliced ​​and combined with each other, the bottom of the liquid crystal screens are connected to a grounding wire, and the mounting frame is provided with a shielding mechanism for shielding the liquid crystal screens.

[0007] In one embodiment, both the left and right parts of the mounting frame are provided with mounting plates to facilitate the installation and fixation of the mounting frame.

[0008] In one of the embodiments, a connector is provided on the grounding wire.

[0009] In one of the embodiments, a handle is also included, and the front side of the LCD screen is connected to the handle.

[0010] In one of the embodiments, the shielding mechanism includes a slide rail, a rotating wheel and a baffle. The rear sides of the upper and lower parts of the mounting frame are connected to the slide rails, and a baffle is provided between the left and right parts of the slide rails. The upper and lower parts of the baffle are rotatably connected to multiple rotating wheels, and the rotating wheels are slidably connected to the adjacent slide rails. The baffle uses the rotating wheels to open and close on the slide rails to shield and protect the LCD screen.

[0011] In one of the embodiments, a cleaning mechanism is also included, which includes a rack, a gear and a cleaning brush. Cleaning brushes are rotatably connected on the side where the baffles are close to each other, and gears are connected to the tops of the cleaning brushes. Racks are connected to the upper slide rails, and the gears are meshed with the racks. When the baffles open and close, the cleaning brushes are driven to move. The movement of the cleaning brushes utilizes the meshing of the gears and the racks to generate rotational force, and the cleaning brushes rotate to clean the surface of the LCD screen.

[0012] The beneficial effects are as follows: 1. The baffle of the utility model utilizes a rotating wheel to perform opening and closing movements on a slide rail, which can shield and protect the LCD screen, avoid exposing the LCD screen, and improve the safety of using the LCD screen.

[0013] 2. The utility model utilizes the opening and closing of the baffle to control the operation of the cleaning brush, which can reduce the dust attached to the LCD screen, reduce the probability of static electricity generation, and increase the service life of the LCD screen.

[0021] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0022] An anti-static LCD screen, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, a liquid crystal screen 2, a grounding wire 3, a handle 4, a fixing block 40 and a shielding mechanism 5. The left and right parts of the mounting frame 1 are both provided with mounting plates to facilitate the installation and fixing of the mounting frame 1. A plurality of fixing blocks 40 are connected to the mounting frame 1, each group is composed of four fixing blocks 40, and each group of fixing blocks 40 is connected to a liquid crystal screen 2. A plurality of liquid crystal screens 2 are connected to the mounting frame 1, and the liquid crystal screens 2 can be spliced ​​and combined with each other. The bottom of the liquid crystal screen 2 is connected to the grounding wire 3, and the grounding wire 3 is provided with a connector. The front side of the liquid crystal screen 2 is connected to a handle 4, and a shielding mechanism 5 is provided on the mounting frame 1.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the shielding mechanism 5 includes a slide rail 51, a rotating wheel 52 and a baffle 53. The rear sides of the upper and lower parts of the mounting frame 1 are connected to the slide rail 51, and a baffle 53 is provided between the left and right parts of the slide rail 51. The upper and lower parts of the baffle 53 are rotatably connected to multiple rotating wheels 52, and the rotating wheels 52 are slidably connected to the adjacent slide rails 51.

[0024] like Figure 1 , Figure 5 and Figure 6 As shown, a cleaning mechanism 6 is also included, which includes a rack 61, a gear 62 and a cleaning brush 63. The cleaning brushes 63 are rotatably connected on the side where the baffles 53 are close to each other, and the tops of the cleaning brushes 63 are connected to the gears 62. The upper slide rail 51 is connected to the rack 61, and the gears 62 are meshed with the rack 61.

[0025] When the utility model is in use, the mounting frame 1 is first fixed to the use area of ​​the liquid crystal screen 2, and then the liquid crystal screen 2 is fixed to the mounting frame 1 through the fixing block 40. The number of liquid crystal screens 2 and the area of ​​the installation are determined by the use requirements. The liquid crystal screen 2 is installed and is still being found. The grounding operation is performed through the grounding wire 3. When the liquid crystal screen 2 is in use, the baffles 53 are pulled to make the baffles 53 move away from each other. When the liquid crystal screen 2 is not in use, the baffles 53 are pushed closer to each other to shield and protect the liquid crystal screen 2. The baffles 53 use the rotating wheel 52 to open and close on the slide rail 51 to shield and protect the liquid crystal screen 2. When the baffles 53 open and close, they will drive the cleaning brush to move. The movement of the cleaning brush uses the meshing of the gear 62 and the rack 61 to generate a rotational force. The cleaning brush rotates to clean the surface of the liquid crystal screen 2, thereby reducing the dust attached to the liquid crystal screen 2 and reducing the probability of static electricity generation.

[0026] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
