The supporting part 21 that is located on the supporting part 21 and being sheathed in the retaining wall 22 in the retaining wall 22 is abutted to downward
It stretches and is formed with boss 23, the boss 23 is corresponded with the groove 13, and the boss 23 is connected on the groove 13.This
In embodiment, there are four the side walls 12, is mutually perpendicular to two-by-two, and the groove 13 has multiple, is respectively arranged on described in four
On side wall 12, the quantity of boss 23 is corresponding with groove 13, and boss 23 is stuck in groove 13, prevents it toward all directions breathing,
It is deformed so as to avoid backlight module, prevents backlight module from failing, it is equally applicable for the backlight module of large scale narrow frame.This
Backlight module deformation, prevents backlight mould caused by the backlight module that utility model provides can effectively prevent middle glue frame 2 to expand with heat and contract with cold
Group failure, is applicable to the backlight module of large scale narrow frame.
Referring to Fig. 3, further, the bottom plate 11 is equipped with reflector plate, the leaded light for being sequentially overlapped setting from down to up
Plate 3 and optical film group 4.
Further, the boss 23 extends on the light guide plate 3, makes the loaded area bigger of boss 23, can be with
It avoids supporting part 21 from sinking, and then prevents supporting part 21 from weighing optical film group 4 wounded.
Incorporated by reference to Fig. 3 and Fig. 4, further, the bottom plate 11 draws hopper 5 equipped at least two, adjacent described to draw material
Reinforcing rib 6 is formed between slot 5, the bottom plate 11 positioned at 12 inside of the side wall, which upwardly extends molding, supporting part 7, described
Supporting part 7 is mutually perpendicular to the bottom plate 11, and the height of the supporting part 7 is less than the height of the side wall 12；The light guide plate 3
On the supporting part 7.It draws and is formed with reinforcing rib 6 between hopper 5, can not only reduce material, lower gold can also be enhanced
The intensity for belonging to frame 1, due to being additionally provided with supporting part 7 on bottom plate 11, and light guide plate 3 is by 7 support of supporting part, since supporting part 7 is the bottom of by
Plate 11 upwardly extends to be formed, and height is higher than the height of bottom plate 11 and reinforcing rib 6, so light guide plate 3 is no longer direct with reinforcing rib 6
Contact, to prevent burr on reinforcing rib 6 from scratching light guide plate 3, when metal frame 1 is slightly distorted instantly, the height that is higher by
It can prevent reinforcing rib 6 from squeezing light guide plate 3, prevent light guide plate 3 from damaging, backlight module provided by the utility model can make to draw hopper
