DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of the integrated front frame structure of a liquid crystal display provided by the present invention; Figure 2 for Figure 1 A schematic structural diagram of the front frame structure shown; Figure 3 for Figure 1 A schematic structural diagram of the heat dissipation hole structure shown; Figure 4 for Figure 1 A schematic structural diagram of the rubber ring structure shown; Figure 5 for Figure 2 An enlarged schematic diagram of part A is shown; Figure 6 for Figure 3 The enlarged schematic diagram of part B is shown. The integrated front frame structure of the liquid crystal display includes: a front frame 1 and a rear frame 3. The display screen 2 is installed between the rear frame 3 and the front frame 1. The four groups of corners on the front side of the rear frame 3 are each provided with a groove 15. The inner wall of each group of the grooves 15 is installed with a guide rod 16. The outer wall of the guide rod 16 is slidably connected to a slider 8. The front end of the slider 8 is installed with a connecting plate 14. The front end of the connecting plate 14 is installed with a second protrusion 12. The second protrusion 12 is a right-angled trapezoid. The side wall of the slider 8 is connected to the inner wall of one side of the groove 15. A spring 7 is installed between the four groups of corner outer walls of the rear frame 3, and the spring 7 is sleeved on the outside of the guide rod 16. The four groups of corner outer walls of the rear frame 3 are slidably connected with round rods 9. One end of the round rod 9 passes through the inside of the groove 15 and is fixedly connected to the side wall of one end of the slider 8. The end of the round rod 9 located outside the rear frame 3 is installed with a bump 5. Rectangular blocks 10 are installed at the four groups of corners of the rear outer wall of the front frame 1. The side walls of the rectangular blocks 10 are provided with rectangular grooves 13. The inner wall of the rectangular groove 13 is in contact with the outer wall of the bump 2 12.

[0023] A rubber ring 11 is installed at the connection between the front frame 1 and the rear frame 3 .

[0024] The rubber ring 11 is composed of a vulcanized butadiene rubber layer 111, a chloroprene rubber layer 112, and an anti-slip layer 113. The vulcanized butadiene rubber layer 111 is positioned on top of the chloroprene rubber layer 112 and is fixedly connected by gluing. The bottom of the chloroprene rubber layer 112 is fixedly connected to the top of the anti-slip layer 113. The provision of the vulcanized butadiene rubber layer 111 provides excellent wear resistance and elasticity of the vulcanized butadiene rubber. The provision of the chloroprene rubber layer 112 provides good overall performance, including oxidation and ozone resistance. The provision of the anti-slip layer 113 ensures high stability between the front frame 1 and the rear frame 3, preventing them from sliding easily.

[0025] The left and right outer walls of the rear frame 3 are each provided with a plurality of heat dissipation holes 4 . The heat dissipation holes 4 are provided to improve the heat dissipation effect of the display screen 2 .

[0026] A nameplate slot 6 is installed on the outer wall of the front lower end of the front frame 1. The nameplate slot 6 is provided to facilitate displaying the nameplate of the display screen.

[0027] The front frame 1 and the rear frame 3 are both made of polycarbonate material. PC material has high strength and impact resistance is its significant advantage. It also has good heat resistance and can maintain stable performance within a certain temperature range.

[0028] The working principle of the integrated front frame structure of the liquid crystal display provided by the present invention is as follows: when the front frame 1 needs to be disassembled, the protrusion 1 5 is pressed in the direction of the side wall of the front frame 1 by hand in sequence. The protrusion 1 5 squeezes the slider 8 through the round rod 9 and moves toward the other end of the guide rod 16. At this time, the spring 7 is in a compressed state. At the same time, the slider 8 drives the protrusion 2 12 to leave the inside of the rectangular groove 13 through the connecting plate 14, thereby releasing the restriction on the rectangular block 10, and the front frame 1 and the rear frame 3 can be separated. When the front frame 1 and the rear frame 3 need to be installed, it is more convenient. After the four groups of rectangular blocks 10 of the front frame 1 are aligned with the four groups of grooves 15 of the rear frame 3, the front frame 1 is pressed backward to insert the rectangular blocks 10 into the grooves 15. The heads of the rectangular blocks 10 squeeze the right-angled trapezoidal protrusions 12 to move them to the other side of the grooves 15. When the rectangular blocks 10 extend into the grooves, the protrusions 12 are flush with the rectangular grooves 13. The compressed springs 7 automatically push the sliders 8 so that the connecting plates 14 drive the protrusions 12 to insert into the rectangular grooves 13, thereby restricting the rectangular blocks 10 and ensuring stable installation of the front and rear frames 1 and 3.

[0029] Compared with related technologies, the integrated front frame structure of the liquid crystal display provided by the present invention has the following beneficial effects:

[0030] Through the interaction of the components such as the first protrusion 5, the round rod 9, the slider 8, the guide rod 16, the spring 7, the connecting plate 14, the second protrusion 12, the rectangular groove 13, the rectangular blocks 10 and the grooves 15, the front frame 1 and the rear frame 3 can be quickly separated without expending much effort. When the front frame 1 and the rear frame 3 need to be assembled, it is more convenient. Only the four groups of rectangular blocks 10 of the front frame 1 are aligned with the four groups of grooves 15 of the rear frame 3, and then the front frame 1 is pressed backward. This greatly facilitates the later inspection and maintenance of the interior of the display screen 2.
