However, the method of using multiple screws 8 to lock the printed circuit board 4 as shown in Figure 1 not only increases the manufacturing cost, but also prolongs the assembly man-hours of the liquid crystal display device and reduces the production efficiency.
And when the printed circuit board 4 is removed, the screw 8 must be removed first, so that the printed circuit board 4 can be separated from the back plate 2
Especially when locking multiple screws 8, it is easy to miss locking the screws 8
Even if only a small amount of screws are not locked on the printed circuit board 4, the printed circuit board 4 cannot be fixed on the backplane 2 evenly.
In addition, it is more difficult to ensure that when each screw 8 is locked to the printed circuit board 4, the consistency of the force applied to the printed circuit board
This results in a decrease in product quality, leading to lower yields

The invention discloses a fixed structure and a back light module with the same. The fixed structure comprises a first wall body provided with at least one first positioning hole, a second wall body provided with at least one second positioning hole, and at least one fixed member. The fixed member is provided with a first part, a second part and a middle part, wherein the first part has a thread structure, the circumference of the second part is provided with at least one groove and at least one clamp hook corresponding to the groove, and the clamp hook moves to the second part when pressed; the first part is combined and fixed with the first positioning hole, the second part passes through and protrudes from the second positioning hole in which the middle part is positioned, and the second wall body is limited between the clamp hook and the first wall body. The back light module is assembled by utilizing the fixed structure with a special structure, and the fixed structure is convenient for the assembly and the disassembly of the back light module, saves assembling time and improves efficiency.
Description
technical field [0001] The present invention relates to a fixing structure, in particular to a fixing structure applied in a backlight module. Background technique [0002] In the backlight module of a general liquid crystal display device, cold cathode lamps or light emitting diodes are used as the backlight. In a liquid crystal display device using light-emitting diodes as a backlight source, the most common method is to solder the light-emitting diodes to a printed circuit board, and use screws to lock the printed circuit board to the backplane of the backlight module. Please refer to FIG. 1 . FIG. 1 is a schematic diagram of assembly of a backlight module in the prior art. The backlight module 1 includes a backplane 2 and a light source, wherein the light source is an LED strip, which is composed of a plurality of LEDs 3 and a printed circuit board 4 , and the LEDs 3 are electrically welded on the printed circuit board 4 . There are a plurality of first positioning hol...
