Description

Technical Field

[0001] The utility model belongs to the technical field of liquid crystal display screens, and in particular relates to a light leakage-proof liquid crystal display screen. Background Art

[0002] Liquid crystal displays (LCDs) are active-matrix displays driven by thin-film transistors. They primarily use electric current to stimulate liquid crystal molecules to create dots, lines, and surfaces, which, in conjunction with backlighting, form the display. Under the influence of an electric field, the alignment of the liquid crystal molecules changes, altering (modulating) the transmittance of an external light source, completing electro-optical conversion. Then, using the different excitations of the three primary colors (R, G, and B) through the red, green, and blue filters, color reproduction in both the temporal and spatial domains is achieved.

[0003] Patent document with announcement number CN221884074U discloses a light leakage proof liquid crystal display screen. The device is assembled and fixed in a suitable position. At this time, the connecting block is fixed in a suitable working place. The main board is started to drive the display screen for use. The connecting block and the locking block are clamped in the fixing groove. At the same time, the locking rod is passed through and fixed in the first locking groove and the second locking groove, so that the bearing shell and the light leakage proof frame are fixed on the connecting block. At this time, the second connecting groove and the first connecting groove are connected to each other. The servo motor is started to drive the fan blade to rotate, so that the air intake grille draws external air into the first connecting groove, and then After passing through the second connecting groove, it is attached to the heat generated by the motherboard and finally passes through the air outlet grille to spray the device. Because it is provided with a clamping mechanism, the locking rod and the clamping block can better share the weight of the bearing shell under the action of the clamping mechanism. At the same time, when installation and disassembly maintenance are required, it can be disassembled and assembled more quickly, thereby reducing the workload of maintenance personnel. Because it is provided with a heat dissipation mechanism, under the action of the heat dissipation mechanism, the motherboard can be better attached to and taken away by the flowing air when dissipating heat, thereby better placing it in a better working environment, further improving the life of the display and motherboard, and ensuring the needs of users.

[0004] The above-mentioned light leakage-proof LCD screen can solve the corresponding technical problems, but its locking block and the supporting block are fixed by multiple locking rods. However, the multiple locking rods are directly arranged in the first locking groove and the second locking groove, and adopt a split structure, which causes the locking rods to loosen or even fall due to collision with external forces, thereby reducing the fixing stability of the locking rods.

[0029] See attached Figure 1-4 As shown, an embodiment of the present invention is a light leakage-proof liquid crystal display screen, comprising a display 100, a heat dissipation mechanism 200 for dissipating heat, and a connecting mechanism 300 for connecting. The heat dissipation mechanism 200 is arranged on the rear side of the display 100, and the connecting mechanism 300 is arranged between the display 100 and the heat dissipation mechanism 200.

[0030] The heat dissipation mechanism 200 includes a housing 210 , a mounting frame 220 is fixedly connected to the surface of the housing 210 , and a fan 230 is installed in the inner cavity of the housing 210 .

[0031] The connecting mechanism 300 includes two groups of hanging parts 310 symmetrically arranged on the surface of the shell 210 and used for limiting position. Each group of hanging parts 310 is provided with two hanging parts 310, and a blocking part 320 for positioning is provided between the four hanging parts 310. The side of the installation frame 220 facing the display 100 is provided with a distance adjustment part 330 that can drive the blocking part 320 to move horizontally.

[0032] When the embodiment of the utility model of the above technical solution is used, the mounting frame 220 is installed in the desired position by screws; then the second hook 312 on the rear shell 130 is hooked on the corresponding first hook 311 to complete the limiting operation; then the screw sleeve 333 is rotated, and under the action of the thread, the screw sleeve 333 drives the movable plate 331 to move on the surface of the stud 332 toward the display 100, and the movable plate 331 drives the frame 321 and the positioning post 322 to move synchronously, and the frame 321 slides to the maximum limit in the inner cavity of the through groove 3111, so that the positioning post 322 passes through the positioning holes 340 on the second hook 312 and the first hook 311 in turn, and the positioning operation is completed, thereby realizing the rapid connection and fixing operation of the display 100 and the heat dissipation mechanism 200; finally, the fan 230 is started to dissipate heat for the display 100.

[0033] In an embodiment of the present invention, the display 100 includes a display screen 110, an anti-light leakage frame 120 is installed in the display screen 110, and a rear shell 130 is installed on the rear side of the display screen 110. The rear shell 130 is in contact with one side of the outer shell 210. The heat dissipation mechanism 200 can dissipate heat for the display 100, thereby further improving the service life of the display 100.

[0034] Specifically, in order to limit the horizontal movement of the display 100 on the heat dissipation mechanism 200, in an embodiment of the present utility model, the hanging member 310 includes a first hook 311 fixedly connected to the surface of the outer shell 210, one side of the first hook 311 is fixedly connected to the mounting frame 220, and the rear side of the rear shell 130 is fixedly connected with a second hook 312 that can be hung on the first hook 311. By hanging the second hook 312 on the corresponding first hook 311, the initial connection between the display 100 and the heat dissipation mechanism 200 can be achieved, thereby achieving a limiting effect.

[0035] In order to ensure the movable space of the second hook 312 located below, in the embodiment of the present utility model, the distance between the two first hooks 311 located above and below is greater than the height of the second hook 312, so that the second hook 312 located below can be hung on the corresponding first hook 311, or removed from the corresponding first hook 311.

[0036] In order to limit the vertical movement of the display 100 on the heat dissipation mechanism 200, in an embodiment of the present utility model, the blocking member 320 includes a frame 321 slidably sleeved on the surface of the housing 210, and the frame 321 is fixedly connected to the side facing the second hook 312 with two groups of symmetrically arranged positioning columns 322, and each group of positioning columns 322 is provided with two upper and lower positioning columns 322, and the positioning columns 322 and the second hooks 312 are arranged in a one-to-one correspondence, and the first hook 311 and the second hook 312 are both provided with positioning holes 340 for the corresponding positioning columns 322 to pass through.

One end of the stud 332 is rotatably connected to the mounting frame 220 through a bearing. A threaded sleeve 333 is provided on the surface of the stud 332, and one end of the screw sleeve 333 is rotatably connected to one side of the movable plate 331 through a bearing. By rotating the screw sleeve 333, the movable plate 331 and the blocking member 320 can be driven to move horizontally under the action of the thread.
