[0038] Please refer to Figs. 1-3 The utility model provides a new technical scheme: a light and thin LED backlight source, comprising aluminum frame 1, the upper surface of aluminum frame 1 is set with placing groove 2;

[0039] Among them, the lower surface of aluminum frame 1 is set with display groove 3, and the display groove 3 extends the bottom wall of placing groove 2 upwards;

[0040] Among them, the LED backlight source body 4 is slidably connected in placing groove 2;

[0042] Further, two sliding grooves 5 are arranged on the upper surface of the aluminum frame 1.

[0043] Wherein, a plurality of second positioning grooves 7 are arranged on the left and right outer surfaces of the aluminum frame 1.

[0044] Wherein, the second positioning groove 7 is communicated with the inside of the sliding groove 5.

[0045] Further, a plurality of first positioning grooves 6 are arranged on the left and right inner walls of the placing groove 2.

[0046] Wherein, the first positioning groove 6 is communicated with the inside of the sliding groove 5.

[0047] Wherein, two sliding blocks 10 are slidingly connected in the two sliding grooves 5.

[0048] Further, a plurality of positioning blocks 8 are slidingly connected with the corresponding second positioning grooves 7.

[0049] Wherein, the positioning block 8 is slidingly connected with the corresponding first positioning groove 6.

[0050] Wherein, a plurality of limiting pieces 11 are fixedly connected on the outer surfaces of the adjacent two sides of the left and right positioning blocks 8.

[0051] Wherein, the limiting piece 11 is slidingly connected with the first positioning groove 6.

[0053] Wherein, a plurality of push springs 9 are fixedly connected on the outer surfaces of the opposite two sides of the two sliding blocks 10.

[0054] Wherein, the opposite two ends of the left and right push springs 9 are fixedly connected with the inner walls of the opposite two sides of the two sliding grooves 5.

[0055] Further, the lower surface of the limiting piece 11 is slidingly connected with the upper surface of the LED backlight source body 4.

[0058] Further, the LED backlight body 4 in the present scheme is the prior art in the existing published patent: CN202221883141.9 a light and thin LED backlight, which will not be described here;

[0059] Further, in use, the two sliding blocks 10 are pushed to move away from each other, thereby driving the positioning blocks 8 and the limiting pieces 11 on the left and right sides to move away from each other. When the limiting pieces 11 on the left and right sides move out of the placement groove 2 during the movement away from each other, the pushing spring 9 is compressed in this process, causing the pushing spring 9 to be compressed and deformed.

[0060] As described above, the LED backlight body 4 is placed in the placement groove 2 at this time, and the two sliding blocks 10 are released. Under the action of the release force of the pushing spring 9, the positioning blocks 8, the sliding blocks 10, and the limiting pieces 11 are reset. In turn, the limiting pieces 11 on the left and right sides limit the LED backlight body 4, preventing the LED backlight body 4 from sliding out of the placement groove 2. In turn, the assembly of the LED backlight body 4 and the aluminum frame 1 is achieved, making the installation of the LED backlight body 4 convenient and fast, the assembly more labor-saving, and the disassembly more convenient, thereby increasing the practicality of the light and thin LED backlight.

[0061] In addition, the disassembly mechanism in the present scheme has a small size and does not increase the thickness of the aluminum frame 1, thereby making the LED backlight more light and thin, thereby facilitating the storage and storage of the light and thin LED backlight, thereby increasing the practicality of the light and thin LED backlight.

[0062] Working principle: when the device is in use, in use, the two sliding blocks 10 are pushed to move away from each other, thereby driving the positioning blocks 8 and the limiting pieces 11 on the left and right sides to move away from each other. When the limiting pieces 11 on the left and right sides move out of the placement groove 2 during the movement away from each other, the pushing spring 9 is compressed in this process, causing the pushing spring 9 to be compressed and deformed.

[0063] As described above, the LED backlight body 4 is placed in the placement groove 2 at this time, and the two sliding blocks 10 are released. Under the action of the release force of the pushing spring 9, the positioning blocks 8, the sliding blocks 10, and the limiting pieces 11 are reset. In turn, the limiting pieces 11 on the left and right sides limit the LED backlight body 4, preventing the LED backlight body 4 from sliding out of the placement groove 2. In turn, the assembly of the LED backlight body 4 and the aluminum frame 1 is achieved, making the installation of the LED backlight body 4 convenient and fast, the assembly more labor-saving, and the disassembly more convenient, thereby increasing the practicality of the light and thin LED backlight.

[0064] And in the scheme, the dismounting mechanism is small in size, does not increase the thickness of the aluminum frame 1, and thus makes the LED backlight source lighter and thinner, and thus facilitates the storage and storage of the light and thin LED backlight source, and thus increases the practicality of the light and thin LED backlight source.
