When the fixing portion is disposed in the first receiving groove, the second fixing hole is aligned with the first fixing hole, so that the thread outside the end of the fixing member can be locked to the internal thread of the second fixing hole.

In summary, since the outer diameter of the external thread on the tail end of the fixing member is larger than the inner diameter of the annular protruding portion in the first fixing hole on the shell after the display screen, the force is pressed into the annular protrusion when the tail end of the fixing member is externally pressed. After the part, the fixing member is stuck in the first fixing hole. In other words, if the support base is detached from the display screen to package the display device, the fixing member will still be stuck in the first fixing hole, and no additional accessory bag is needed to accommodate the fixing member, so as to avoid the missing of the fixing member. risks of. In addition, since the fixing member is locked in the first fixing hole, the user only needs to fix the fixing portion of the supporting base in the first receiving groove on the shell behind the display screen, thereby quickly locking the fixing member to the fixing member. The second fixing hole on the fixing portion of the supporting base or the second fixing hole on the fixing portion of the supporting base is quickly disassembled for the purpose of quickly disassembling the supporting base.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

Please refer to FIG. 3 to FIG. 6 , FIG. 3 is a schematic diagram of a display device 3 according to a first embodiment of the present invention, and FIG. 4 is a disassembled view of the display device 3 in FIG. 3 , and FIG. 3 is a cross-sectional view of the display device 3 along the line XX, and FIG. 6 is a partial cross-sectional view of the display screen 30 in FIG. As shown in FIGS. 3 to 6, the display device 3 includes a display screen 30, a fixing member 32, a support base 34, and an elastic member 36. In practical applications, the display device 3 can be a liquid crystal display or other flat display.

The display screen 30 includes a rear housing 300, a first receiving slot 302 and a first fixing hole 304 formed on one side of the rear housing 300, and the first fixing hole 304 has an annular protrusion 306 therein. The fixing member 32 includes a head end 320 and a tail end 322 opposite to the head end 320. The tail end 322 has an external thread 3220, and the outer diameter D1 of the external thread 3220 is larger than the inner diameter D2 of the annular protrusion 306. Before the display device 3 is shipped from the factory, the operator can first sleeve the elastic member 36 on the fixing member 32, and then press the outer end 322 of the fixing member 32 into the annular protruding portion 306 of the first fixing hole 304 to The fixing member 32 is locked in the first fixing hole 304. In other words, the fixing member 32 is disposed in the first fixing hole 304 through the annular projection 306 with the trailing end 322. At this time, the elastic member 36 is also disposed in the first fixing hole 304 and located between the tip end 320 of the fixing member 32 and the annular protrusion 306. Thereby, when the display device is packaged, even if the support base 34 is detached from the display screen 30, the fixing member 32 is still stuck in the first fixing hole 304, and no additional accessory bag is needed to accommodate the fixing member. 32, to avoid the risk of the fastener 32 being lost.

As shown in FIG. 6, the elastic member 36 can provide an elastic force to cause the head end 320 of the fixing member 32 to float from the first fixing hole 304, and the external thread 3220 on the trailing end 322 of the fixing member 32 abuts The annular protrusion 306 prevents the fixing member 32 from falling out of the first fixing hole 304. In other words, when the support base 34 has not been assembled with the display screen 30, the elastic member 36 can provide an elastic force so that the fixing member 32 does not fall downward by gravity to facilitate subsequent assembly. In practical applications, the elastic member can be a spring, but is not limited thereto.

The support base 34 includes a fixing portion 340 , and a second fixing hole 342 is formed on the fixing portion 340 and has an internal thread 3420 . Since the fixing member 32 is locked in the first fixing hole 304 of the rear case 300 when the display device 3 is shipped from the factory, the user only needs to fix the fixing portion 340 of the supporting base 34 when assembling the display screen 30 and the supporting base 34. The first receiving groove 302 of the rear case 300 is inserted. As shown in FIG. 5, when the fixing portion 340 of the supporting base 34 is disposed in the first receiving groove 302 of the rear case 300, the second fixing hole 342 of the fixing portion 340 is aligned with the first fixing hole 304 of the rear case 300. .
