[0024] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0025] Example:

[0026] like Figure 1-Figure 5 As shown, a backlight display device includes a shell 1, both sides of the shell 1 are provided with fixed through grooves 2, the inner side of the shell 1 is provided with a circuit board 3, the bottom of the circuit board 3 is provided with an LED light source 4, the inner side of the shell 1 is provided with a light guide plate 5, the upper part of the light guide plate 5 is provided with a diffusion film 6, the outer side of the surface of the circuit board 3 is fixedly sleeved with a lampshade 8, the outer bottom of the edge of the lampshade 8 is provided with a reflective plate 7, and both sides of the lampshade 8 are fixedly connected with heat sinks 9.

[0027] The working principle of the above technical solution is as follows:

[0028] During use, the heat sink 9 can be stuck on the inner side of the fixed through groove 2 and be outside the whole body, so that the heat generated during use can be quickly dissipated to the outside, thereby dissipating the heat inside the whole body and improving the overall stability of use.

[0029] In another embodiment, if Figure 1 and Figure 2 As shown, a connecting cover mechanism 10 is provided on the top of the housing 1, and threaded holes 11 are provided at the front and rear ends of the housing 1.

[0030] It is convenient to connect and cooperate between the cover mechanism 10 and the threaded hole 11, so that the overall connection can be in a stable state, and thus the whole can be in a stable connection and use state.

[0031] In another embodiment, if Figure 1 , Figure 3 and Figure 4As shown, there are a plurality of heat sinks 9 and a plurality of fixing slots 2 , and the outer surfaces of the heat sinks 9 and the inner surfaces of the fixing slots 2 are fitted together.

[0032] The heat sink 9 can be stably stuck on the inner side of the fixed through groove 2, so as to be connected and matched, and the heat can be quickly dissipated to the outside, which is easy to operate.

[0033] In another embodiment, if Figure 2 As shown, the inner side of the lampshade 8 and the outer side of the surface of the circuit board 3 are in contact with each other.

[0034] This facilitates the lampshade 8 to be stably sleeved on the outer surface of the circuit board 3 , thereby restricting and fixing the circuit board 3 .

[0035] In another embodiment, if Figure 2 and Figure 5 As shown, the connecting capping mechanism 10 includes a connecting frame 12, and a fixed connecting block 13 is fixedly connected to the middle of the front and rear bottom ends of the connecting frame 12, and a threaded sleeve 14 is fixedly connected to the surface of the fixed connecting block 13, and a machine bolt 15 is provided inside the threaded sleeve 14.

[0036] The connecting frame 12 can be conveniently covered on the top of the shell 1 and the top of the lampshade 8, so that the fixed connecting block 13 fits the front and rear surfaces of the shell 1, and by rotating the installation machine bolt 15, the machine bolt 15 can be inserted into the threaded sleeve 14, the fixed connecting block 13 and the inner side of the threaded hole 11, so as to quickly connect and fix. Conversely, it can also be quickly disassembled and the whole can be disassembled for maintenance and repair, which is easy to operate.

[0037] In another embodiment, if Figure 2 and Figure 5 As shown, the machine bolt 15 is connected to the threaded hole 11 and the threaded sleeve 14 through threads.

[0038] It is convenient for the machine bolt 15 to be stably inserted into the inner side of the threaded hole 11 and the threaded sleeve 14, and to be stably connected and fixed, and the operation is convenient.

[0039] In another embodiment, if Figure 2 As shown, the cross-section of the connecting frame 12 is concave, and the outer side of the edge of the lampshade 8 fits with the inner side of the housing 1 .

[0040] The connecting frame 12 can cover the top of the housing 1 and limit the position of the lampshade 8 at the same time, and the lampshade 8 can also be stably located on the inner side of the housing 1, so that the whole can be used stably.

[0041] The working principle of the utility model: during use, when the circuit board 3 and the LED light source 4 are in use, the heat can be absorbed by the lampshade 8 and the heat can be transferred to the inside of the heat sink 9. At the same time, the heat sink 9 can stably and quickly dissipate the heat to the outside air, so that the heat can be quickly dissipated, so that the whole can be used stably. When it is necessary to inspect and maintain the inside, the machine bolt 15 can be quickly rotated and disassembled, and then the whole can be quickly disassembled and decomposed, so that it can be quickly inspected and maintained. The overall structure is simple and the operation is convenient and quick.

[0042] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
