[0019] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] A backlight module limit installation device, such as Figure 1-Figure 5As shown, it includes a bracket 2, a mounting plate 1 is installed on the bracket 2, a heat dissipation hole 3 is opened on the upper part of the mounting plate 1, the left and right parts of the mounting plate 1 are connected to the first clamping block 4, the upper and lower parts of the mounting plate 1 are connected to the second clamping block 5, and the front side of the mounting plate 1 is connected to two guide columns 6, the guide columns 6 are slidably connected with threaded rings 7, springs 10 are connected between the threaded rings 7 and the adjacent guide columns 6, and connecting seats 9 are threadedly connected on the threaded rings 7. The connecting seats 9 are provided with triangular ribs for reinforcement, a backlight module 8 is connected between the two connecting seats 9, and rubber pads for protection are provided on the four corners of the backlight module 8. The backlight module 8 has multiple heat dissipation slots, a screen 11 is clamped between the first clamping block 4 and the second clamping block 5, and the screen 11 is contact-connected to the backlight module 8.

[0021] It should be noted that the backlight module of the display screen is one of the most critical components in the liquid crystal display. It is mainly used to provide light source for the non-self-luminous liquid crystal panel, so that the screen can display bright and clear images. The backlight module is installed on the back side of the screen to provide light source for the screen to display images. First, the backlight module 8 is threadedly connected to the mounting plate 1 through the threaded ring 7 and the connecting seat 9. Then, the screen 11 is clamped to the mounting plate 1 through the first clamping block 4 and the second clamping block 5. During the clamping process, the backlight module 8 may be squeezed by the screen 11 and damaged. When the backlight module 8 is squeezed, the spring 10 is compressed. The backlight module 8 shrinks, thereby driving the backlight module 8 to slide on the guide column 6, so that the backlight module 8 is buffered. At the same time, the rubber pads on the four corners of the backlight module 8 play a protective role. The heat dissipation holes 3 and the heat dissipation grooves on the upper part of the backlight module 8 can dissipate the heat on the backlight module 8 to prevent the backlight module 8 and the screen 11 from being damaged due to excessive temperature. The backlight module 8 is spirally connected to the mounting plate 1 to position the backlight module 8 on the mounting plate 1, so that the backlight module is limited and fixed. The card-type installation method of the mounting plate 1 and the screen 11 makes it easier to disassemble and replace the backlight module, which is beneficial to improving the installation efficiency of the backlight module 8.

[0022] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
