[0002] Liquid crystal displays (LCDs) are used for television and computer screen displays. Their advantages include low power consumption, compact size, and low radiation. LCDs utilize a liquid crystal solution between two polarized materials. When an electric current passes through the liquid, the crystals rearrange to create an image. However, LCDs currently suffer from side light leakage, which occurs when the LCD screen is loosely fitted to the frame, allowing light from the lamp to pass through.

[0003] The Chinese patent with announcement number CN202320515685.8 discloses a side anti-light leakage structure for a liquid crystal display screen, which relates to the technical field of liquid crystal display screens, including a liquid crystal display screen body and a bottom shell, wherein corner frames are provided at the four corners of the liquid crystal display screen body, and horizontal frames are fixedly connected between the left and right sides of the two oppositely arranged corner frames, and vertical frames are provided between the top and bottom positions of the two oppositely arranged corner frames, and the interiors of the two vertical frames and horizontal frames are fixedly connected with light shielding sheets, and the light shielding sheets are slidably connected to the liquid crystal display screen body. The above-mentioned device is tightly fitted with the liquid crystal display screen body by a frame composed of corner frames, horizontal frames, vertical frames, light shielding sheets and small bolts, which can not only protect the outside of the liquid crystal display screen body, but also can shield the side of the liquid crystal display screen body under the action of the light shielding sheets, thereby avoiding the phenomenon of light leakage on the side of the liquid crystal display screen body when in use.

[0004] There is a lack of buffer between the display screen body and the corner frame and horizontal frame. When accidentally hit, the display screen is easily damaged. There is room for improvement. Utility Model Content

[0026] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0027] like Figures 1-4As shown, the embodiment of the utility model has an anti-light leakage structure at the edge of the liquid crystal display screen, which includes a mounting base 1, a protective cover 5 is plugged into the top of the mounting base 1, a limiting frame 3 is provided in the mounting base 1, a liquid crystal display screen 4 is clamped in the limiting frame 3, a heat conducting plate 7 is fixedly connected to the inside of the limiting frame 3, and heat sinks 8 are arranged in an equidistant array at the bottom of the heat conducting plate 7, and an edge anti-light leakage component 6 is provided in the mounting base 1.

[0028] An inflatable cylinder 602 is fixedly connected to the inside of the mounting base 1, a piston 605 is slidably connected to the inside of the inflatable cylinder 602, a sliding rod 603 is fixedly connected to the top of the piston 605, a pressure plate 604 is fixedly connected to the top of the sliding rod 603, an inflatable tube 606 is fixedly connected to the surface of the inflatable cylinder 602, a rubber ring 601 is fixedly connected to the top of the limit frame 3, and the inflatable tube 606 is fixedly connected to the rubber ring 601.

[0029] The above technical solution provides an inflatable cylinder 602. After the LCD screen 4 is installed, the protective cover 5 is clamped to the surface of the mounting base 1. At this time, the protective cover 5 moves downward, and the LCD screen 4 drives the heat conducting plate 7 downward, squeezing the pressure plate 604. The pressure plate 604 then drives the sliding rod 603 and piston 605 downward, sending the air in the inflatable cylinder 602 into the inflation tube 606, causing the rubber ring 601 to expand. This not only provides a buffer between the protective cover 5 and the LCD screen 4, but also prevents light leakage from the edge of the LCD screen 4, facilitating use. A cavity 2 is provided within the mounting base 1.

[0030] In order to better dissipate heat for the LCD screen 4, the mounting base 1 is provided with heat dissipation holes 12 on its surface, which are arranged correspondingly to the heat sink 8. The heat generated by the LCD screen 4 is transferred through the heat conducting plate 7 to the heat sink 8 for heat exchange with the air.

[0031] In order to cushion the LCD screen 4 and reduce the impact of vibration on the LCD screen 4, telescopic columns 10 are symmetrically arranged at the bottom of the limit frame 3. The bottom of the telescopic columns 10 is slidably connected to the fixed columns 9, and a spring 11 is arranged between the limit frame 3 and the fixed columns 9.

[0032] In order to better fix the protective cover 5, a positioning hole is opened on the top of the mounting base 1, and a plug rod with the same size as the positioning hole is fixedly connected to the bottom of the protective cover 5. The plug rod is inserted into the positioning hole to fix the protective cover 5, and the LCD screen 4 is pressed and fixed by the protective cover 5.

[0033] To allow the rubber ring 601 to expand and seal the LCD screen 4, an air chamber is provided inside the rubber ring 601. The rubber ring 601 is positioned between the protective cover 5 and the limiting frame 3. A buffer layer is provided on the surface of the limiting frame 3. The buffer layer provides a flexible connection between the limiting frame 3 and the LCD screen 4.

[0034] In order to reduce weight, the mounting base 1 and the protective cover 5 are configured as plastic shells, and the heat conducting plate 7 and the heat sink 8 are configured as metal plates. The heat conducting plate 7 and the heat sink 8 are configured as metal plates to improve heat dissipation efficiency.

[0035] In order to facilitate wire management, the inner size of the protective cover 5 is the same as that of the LCD screen 4 , and a wire management hole electrically connected to the LCD screen 4 is opened on the mounting base 1 .

[0036] In summary, in the embodiment of the utility model, an inflatable cylinder 602 is provided in the anti-light leakage structure at the edge of the liquid crystal display screen. After the liquid crystal display screen 4 is installed, the protective cover 5 is clamped on the surface of the mounting base 1. At this time, the protective cover 5 moves downward, and the liquid crystal display screen 4 drives the heat conduction plate 7 to move downward, squeezing the pressure plate 604. At this time, the pressure plate 604 drives the sliding rod 603 and the piston 605 to move downward, and the air in the inflatable cylinder 602 is sent into the inflation tube 606, so that the rubber ring 601 expands and becomes larger, which can not only provide a buffer between the protective cover 5 and the liquid crystal display screen 4, but also prevent light leakage at the edge of the liquid crystal display screen 4, making it easy to use.

[0037] The above shows and describes the basic principles of the present invention. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification are only to illustrate the principles of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the spirit and scope of the present invention should be included in the scope of protection of the present invention.
