Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, specifically to an anti-interference touch liquid crystal display. Background Technology
[0002] Touchscreen LCD displays have advantages such as low power consumption, thinness, and low cost, and are widely used in daily life. A search revealed that Chinese patent publication number CN208488735U discloses a high anti-interference LCD display device. Although the anti-interference frame on the surface of the display device can isolate the external magnetic field from the internal components, effectively preventing external magnetic field interference and improving anti-interference performance, existing LCD displays need to be kept horizontal to ensure stable installation when mounted on a wall. However, since the angle cannot be adjusted after the display is fixed, the display needs to be precisely positioned before installation, which increases the installation difficulty. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an anti-interference touch LCD screen, which solves the problem mentioned in the background art that existing LCD screens require high horizontal precision during installation, leading to significant installation difficulties.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference touch LCD display, comprising an anti-interference housing, a back plate, a connecting block, a base, and an adjusting block. An LCD screen is disposed inside the anti-interference housing, a backlight module is disposed on the back of the LCD screen, and a circuit board is disposed on the back of the backlight module. The anti-interference housing and the back plate are connected by bolts. Two sliding rods are disposed on one side of the back plate, with a slider welded to one end of each sliding rod. One end of each sliding rod is located inside the connecting block. A base is disposed on one side of the connecting block, and the base is tightly fitted to the surface of the connecting block. The base is connected to the connecting block by connecting bolts. Two adjusting blocks are disposed inside the connecting block, with a slot at one end for docking with the display screen bracket.
[0005] Preferably, one side surface of the back plate has teeth distributed in a ring at equal intervals. The teeth on the back plate surface engage with the teeth on one side surface of the connecting block. The engagement of the teeth on the back plate and the connecting block increases the friction and bonding strength between them, making the display screen more stable after installation and reducing displacement or shaking caused by external forces or vibrations. This improves the reliability and lifespan of the display screen. When the display screen needs to be adjusted, pulling the anti-interference shell outward can separate the teeth on the back plate surface from the teeth on the connecting block, allowing the display screen to rotate. This ensures that the display screen can still be easily adjusted after installation.
[0006] Preferably, two arc-shaped slots are formed on one side surface of the connecting block. The inside of the arc-shaped slots on the surface of the connecting block slides in contact with the outer wall of the slide rod. A spring is fitted on the outside of one end of the slide rod. The slider at the end of the slide rod slides in contact with the inner wall of the annular groove on the other side surface of the connecting block. When the angle of the display screen is adjusted, when the display screen is released, the elastic force of the spring will push the slide rod through the slider, causing the slide rod to pull the back plate and the connecting block to re-fit. This realizes the automatic reset function after the display screen angle is adjusted, ensuring that the display screen can quickly return to a stable state after adjustment.
[0007] Preferably, the base has limit grooves at both ends, and two sliding grooves are formed on the inner wall surface of the limit grooves. The two sliding grooves on the inner wall of the limit grooves are slidably connected to the strip-shaped protrusions on the surface of the adjusting block. The sliding connection between the two sliding grooves on the inner wall surface of the limit grooves and the strip-shaped protrusions on the surface of the adjusting block allows the adjusting block to slide smoothly along the direction of the sliding grooves within the limit grooves.
[0008] Preferably, the other end of the adjusting block is provided with a slot, and the slot is threadedly connected to a bolt. One end of the adjusting block is in contact with the surface of the limiting groove. The surface of the limiting groove is provided with strip-shaped protrusions in a straight line at equal intervals. The other end of the adjusting block is provided with a slot, and the slot is threadedly connected to a bolt. This allows the adjusting block to be fixed in the limiting groove by bolts, ensuring that the adjusting block remains stable after installation and will not loosen due to external forces.
[0009] This invention provides an anti-interference touch LCD screen. It has the following beneficial effects:
[0010] (1) The anti-interference touch LCD screen, when installed, the adjustment block is fixedly connected to the screen bracket by bolts, and the screen bracket is fixed to the wall. There is no need to perform horizontal positioning in advance. When the height of both ends of the screen needs to be adjusted after the screen is fixed, the anti-interference shell is pulled outward, so that the teeth on the back plate surface can be separated and engaged with the teeth on one side of the connecting block, so that the screen can be rotated and the height of both ends of the screen can be adjusted, so that the screen can be kept horizontal. After the screen is released, the slider can be pushed by the spring, so that the slider can pull the back plate and the connecting block to fit together, so that the back plate and the connecting block can be positioned by the meshing, which greatly reduces the difficulty of screen installation and positioning.
[0011] (2) The anti-interference touch LCD screen can loosen the bolt at one end of the adjustment block, thereby allowing the bolt at one end of the adjustment block to disengage from the limiting groove, so that the adjustment block can slide inside the limiting groove, thereby adjusting the hole-groove distance between the two adjustment blocks. This makes it easier for the adjustment block to be used in the installation of display brackets with different hole spacings, greatly improving the applicability of the display screen.
[0012] This solves the problem of high horizontal accuracy requirements during the installation of existing LCD screens, which makes installation difficult. Attached Figure Description
