It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Figures 1 to 4, the utility model provides an assembly structure of a liquid crystal television, which includes a front case 100, a rear case 200, and a liquid crystal screen assembly 300 and a machine set in the space enclosed by the front case 100 and the rear case 200 core board (not shown in the figure). The assembly structure further includes a surrounding frame 400 disposed in the front case 100 , and the liquid crystal screen assembly 300 is placed in the surrounding frame 400 . The surrounding frame 400 is set in the front case 100 to enhance the strength of the front case 100. Meanwhile, the liquid crystal screen assembly 300 is placed in the surrounding frame 400 to limit the position of the liquid crystal screen assembly 300 and prevent it from moving around. The inner side of the frame wall of the surrounding frame 400 is provided with a number of card positions 410, and a number of hooks 210 protrude from the inner surface of the rear shell 200. The through groove 220 of the shell 200 . In the present utility model, the screwless connection between the front shell 100 and the rear shell 200 is realized by utilizing the cooperation of the hook 210 and the clamping position 410 . When the hook 210 is separated from the locking position 410 , the rear case 200 can be ejected naturally, thereby separating the front case 100 from the rear case 200 .

5 and 6, in this embodiment, the surrounding frame 400 is a rectangular hollow frame. When the surrounding frame 400 is placed in the front case 200, there is a gap 500 between the frame wall of the surrounding frame 400 and the side wall of the front case 200. , during installation, the side wall of the rear case 200 is inserted into the gap 500 , and the hooks 210 on the rear case 200 protrude from the gap 500 to be engaged with the respective locking positions 410 . In this way, the fixed connection of the rear case 200 with the surrounding frame 400 and the front case 200 is realized.

Further, in this embodiment, each hook 210 is provided with a limiting column 230 inside, and each limiting column 230 is against the rear wall of the liquid crystal screen assembly 300 . After the rear case 200 and the front case 100 are installed, the back wall of the liquid crystal screen assembly 300 is pushed against the rear wall of the liquid crystal screen assembly 300 by the limit post 230. The rear case 200 plays a supporting role, preventing the rear case 200 from being dented inward.

In this embodiment, the locking position 410 is a locking slot, and the hook 210 includes a column 211 protruding from the rear case 200 and a hook portion 212 disposed at the front end of the column 211 and hooked into the slot. The hook 210 is not limited to this structure and can also be of other structures. Similarly, the locking position 410 can also be a locking hole.

Referring to FIG. 3 again, the rear wall of the liquid crystal display assembly 300 protrudes from the wall studs 310 , and the rear shell 200 is correspondingly provided with a wall hole 240 through which the wall studs 310 can pass. In this way, the wall-mounting stud 310 is fixed on the wall through the wall-mounting hole 240, and the LCD TV can be fixed on the wall.

In this embodiment, the assembly structure further includes a support base 600, here, there are two support bases 600, of course, there may be one support base. Each support base 600 is provided with a mounting hole 610 , the inner surface of the rear case 200 is provided with a rivet post 250 , and the rear wall of the liquid crystal panel assembly 300 is provided with a hollow post 320 corresponding to the rivet post 250 . During installation, the rivet post 250 is inserted into the hollow post 320 through the installation hole 610. At this time, the support seat 600 is sandwiched between the LCD panel assembly 300 and the rear case 200, and the LCD TV can be placed on the back cover 200 by using the support seat 600. on the desktop.

In this embodiment, a fixing hole 330 for fixing the core board (not shown in the figure) is further provided on the rear wall of the liquid crystal screen assembly 300 .

Further, a row of evenly distributed cooling holes 260 is provided on the rear case 200 . In this way, the heat generated by the liquid crystal screen assembly 300 and the core board can be dissipated in time through the cooling holes 260 .

When assembling the LCD TV in this embodiment, the front case 100 with the built-in frame 400 is first placed horizontally, then the liquid crystal screen assembly 300 is placed in the frame 400, and the fixing holes on the rear wall of the liquid crystal screen assembly 300 are used 330 fixes the movement board. If the LCD TV needs to be placed on the desktop, the mounting hole 610 on the support base 600 is placed on the hollow column 320. If the LCD TV is installed on the wall, the support base 600 is not needed here , and finally cover the rear case 200, snap the side wall of the rear case 200 into the gap 500 between the side wall of the front case 100 and the surrounding frame 400, and extend the hook 210 on the rear case 200 into the locking position 410 At this time, the limit post 230 is against the rear wall of the LCD panel assembly 300, and the rear case 200 is released. Under the plastic reaction force of the limit post 230, the rear case 200 pops out. . During this process, the wall-mounting studs 310 are correspondingly inserted into the wall-mounting holes 240 of the rear case 200 . At this moment, under the two-way action of the limiting column 230 against the top and the wall-hanging stud 310 , the rear case 200 will not sag, and the liquid crystal screen assembly 300 will not move backward.

When disassembling the LCD TV in this embodiment, use a flat-head screwdriver to extend through the through groove 220 on the surface of the rear case 200, and open each hook 210 to separate it from the corresponding card position 410. At this time, the rear case 200 is separated from the surrounding frame 400, so that the LCD TV is opened, and after maintenance, it can be assembled according to the above assembly steps.

In this embodiment, the LCD TV adopts this screwless assembly method, which is fast and convenient for installation, high in production efficiency, and convenient for maintenance and disassembly.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model should be included in the utility model. within the scope of protection.
