[0019] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0020] See also Figure 2 , Figure 4 and Figure 5The utility model provides an ultra-thin light leakage-proof liquid crystal display screen frame, comprising an adjustable frame structure 1, the adjustable frame structure 1 comprising an inner frame 11, a movable side frame 12, a guide groove 13, a screw 14, a cross head 15 and a threaded sleeve 16, the movable side frames 12 are symmetrically arranged on the left and right sides of the inner side of the inner frame 11, the top of the movable side frame 12 is slidably connected to the inner frame 11 by a slide rail, the lower ends of the left and right sides of the inner frame 11 are horizontally provided with guide grooves 13, and the top of the guide grooves 13 penetrates to the inner bottom surface of the inner frame 11, and the inner wall end of the guide groove 13 is connected to the inner side of the inner frame 11 by a bearing. The screw rod 14 is rotatably connected, and the screw rod 14 is horizontally arranged. A cross head 15 is integrally arranged at the head end of the screw rod 14. A threaded sleeve 16 is provided on the outer surface of the screw rod 14, and the threaded sleeve 16 is fixedly connected to the bottom end of the movable side frame 12. A screwdriver is used to turn the cross head 15 to control the rotation of the screw rod 14, so that the screw rod 14 drives the threaded sleeve 16 to move along the inner side of the guide groove 13 to drive the movable side frame 12 to move horizontally, thereby realizing the movement and adjustment of the movable side frame 12, so that the movable side frame 12 can fit tightly on the edge of the display panel, and it is not easy to produce a gap, thereby reducing the occurrence of light leakage problems.

[0021] To further explain, the inner wall of the movable side frame 12 is paved with a shading pad 121, wherein the shading pad 121 is made of black rubber material as a whole. The shading pad 121 can be filled between the movable side frame 12 and the display panel to play a buffering role, thereby preventing the movable side frame 12 from pinching the display panel. At the same time, the shading pad 121 can also seal the gap between the movable side frame 12 and the display panel to prevent light from leaking out and causing light leakage problems.

[0022] To further illustrate, the travel length of the threaded sleeve 16 on the surface of the screw rod 14 is at least 2.5 cm, so that the movable side frame 12 has sufficient adjustment margin, which is conducive to the rapid disassembly and assembly of the display panel and the inner frame 11.

[0023] See also Figure 1 and Figure 3 The adjustable frame structure 1 in the present invention further includes an outer frame 17, which can be buckled on the surface of the inner frame 11 from the front. The outer frame 17 can cover the inner frame 11 to prevent the connection structure on the inner frame 11 from being exposed and affecting the aesthetics of the display screen.

[0024] To further explain, the outer frame 17 and the inner frame 11 are fixed by means of a snap-on connection, wherein protruding buckles 18 are provided on the upper and lower outer edges of the inner frame 11, and buckle grooves 19 are provided on the upper and lower inner edges of the outer frame 17. The protruding buckles 18 can be snapped together with the inner sides of the buckle grooves 19, thereby realizing the snap-on connection between the outer frame 17 and the inner frame 11, so that no connecting structures such as screw holes are left on the surface of the outer frame 17, thereby ensuring aesthetics.

[0025] Here’s how it works:

[0026] First, before installation, first use a screwdriver to turn the cross head 15 to control the screw 14 to rotate in the opposite direction, so that the screw 14 drives the threaded sleeve 16 to move along the inner side of the guide groove 13, to drive the movable side frame 12 to move horizontally, so that the distance between the movable side frames 12 on both sides of the inner frame 11 is increased, to ensure that the display panel can be smoothly placed inside the inner frame 11, thereby completing the installation preparation work.

[0027] Second, during installation, first place the display panel inside the inner frame 11. After confirming that the display panel is in place, use a screwdriver to turn the cross head 15 to control the screw 14 to rotate forward, thereby driving the movable side frames 12 on both sides of the inner frame 11 to move toward each other, until the movable side frames 12 are clamped on both sides of the display panel. This can ensure that the movable side frames 12 and the display panel are tightly fitted, and it is not easy to produce gaps, thereby reducing the occurrence of light leakage problems. In addition, by providing a shading pad 121 on the inner side wall of the movable side frame 12, the shading pad 121 can be filled between the movable side frame 12 and the display panel to play a buffering role, thereby preventing the movable side frame 12 from clamping the display panel. At the same time, the shading pad 121 can also seal the gap between the movable side frame 12 and the display panel to prevent light from leaking out and causing light leakage problems.

[0028] Third, after the display panel and the inner frame 11 are installed, the outer frame 17 is buckled onto the surface of the inner frame 11 from the front. During this process, the protruding buckle 18 will buckle with the inner side of the buckle groove 19, thereby realizing the buckling connection between the outer frame 17 and the inner frame 11. The outer frame 17 can cover the inner frame 11 to prevent the connection structure on the inner frame 11 from being exposed and affecting the aesthetics of the display screen.

[0029] The utility model provides an ultra-thin anti-light leakage liquid crystal display screen frame, which is provided with an adjustable frame structure 1, and the display panel is placed inside the inner frame 11. After confirming that the display panel is placed in place, a screwdriver is used to twist the cross head 15 to control the screw rod 14 to rotate forwardly, so as to drive the movable side frames 12 on both sides of the inner frame 11 to move towards each other, until the movable side frames 12 are clamped on the two sides of the display panel, so as to ensure that the movable side frames 12 are closely fitted with the display panel, and it is not easy to generate a gap, thereby reducing the generation of light leakage problems. In addition, a light shielding pad 121 is provided on the inner side wall of the movable side frame 12, and the light shielding pad 121 can seal the gap between the movable side frame 12 and the display panel, so as to prevent light from leaking out and causing light leakage problems. By providing an outer frame 17, after the display panel and the inner frame 11 are installed, the outer frame 17 is buckled on the surface of the inner frame 11 from the front, so that the outer frame 17 covers the inner frame 11, so as to prevent the connection structure on the inner frame 11 from being exposed and affecting the aesthetics of the display screen.
