Therefore, the design of the back panel 50 and the connecting member 60 can realize the rapid installation and disassembly of the display device. When the display device needs to be maintained, it is only necessary to loosen the third locking member. Part of the third locking member is a screw structure for screwing with the second locking hole 53, and the other part is a cylindrical part. In order to achieve rapid installation and disassembly, the outer surface of the cylindrical part is knurled, and loosening and locking can be achieved manually without the help of other tools.

[0043] The installation and disassembly principles of the display device of the present invention are as follows:

[0044] During installation, after aligning the multiple card slots 101 with the buckle 21, press down on the side away from the card slot 101, and generate pressure on the spring 40. The spring 40 stores elastic potential energy and then keeps pressed. The first locking member 30 passes through the first through hole 22 and is screwed to the internal threaded hole 102.

[0045] When disassembly is required, the first locking member 30 is loosened, and under the action of the spring 40, one side of the display device 10 automatically pops up, and the display device can be removed from the rear housing 20 without the need for prying or turning the display device with other tools.

[0046] In summary, the display device of the present invention can be installed by providing a snap-on card slot and cooperating with a first locking member. In this way, at least one first locking member is required to achieve installation, which is convenient for disassembly. Moreover, the first locking member can be provided below the rear shell to avoid damage to the appearance of the desktop terminal. Specifically:

[0047] First, the display screen is designed to automatically pop up for easy disassembly. It uses a spring + snap-on slot combined with a small number of screws to lock it. This method only requires removing two screws, and the spring inside will automatically pop up, allowing for quick disassembly.

[0048] Second, the unique assembly design makes after-sales maintenance easy. Even customers, without any technical knowledge, can easily replace the screen by simply unscrewing two semi-hidden screws at the bottom. This not only improves the efficiency of screen replacement, but also greatly reduces the difficulty and cost of replacement.

[0049] Third, its design changes the conventional form of numerous external screws or clips, and only two semi-hidden screws are designed on the bottom of the back shell to ensure the integrity of the display appearance.

[0050] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
