[0047] Referring to Figures 1 to 4 The present application provides a waterproof display screen convenient to assemble, comprising: a front shell assembly 10, a display screen assembly 20, a metal pressing plate 30 and a rear shell assembly 40, the display screen assembly 20 is installed on the front shell assembly 10 through the metal pressing plate 30; wherein the metal pressing plate 30 is provided with a screw fixing ear 303, the screw fixing ear 303 is provided with a through hole, the screw fixing ear 303 is fixedly connected between the front shell assembly 10 through locking screws, the display screen assembly 20 is located between the metal pressing plate 30 and the front shell assembly 10; the rear shell assembly 40 is fixedly connected with the front shell assembly 10, so as to seal the display screen assembly 20 and the metal pressing plate 30 in the space between the front shell assembly 10 and the rear shell assembly 40.

[0048] Specifically, as Figure 1 and Figure 2As shown in the figure, the front shell assembly 10 and the rear shell assembly 40 can be fixedly connected by screws, and after the front shell assembly 10 and the rear shell assembly 40 are fixedly connected, a relative sealed space can be formed between the front shell assembly 10 and the rear shell assembly 40, which can prevent dust, gas or liquid from directly entering the inside of the display screen, thereby playing a certain waterproof and dustproof role, and further protecting the display screen assembly 20 and other circuit components in the display screen.

[0049] As shown in the figure, Figure 3 and Figure 4 , the front shell assembly 10 is provided with a display screen mounting position 101, the display screen mounting position 101 is provided with a display window 1011, the display surface of the display screen assembly 20 faces the display window 1011, and the metal pressing plate 30 is fixedly pressed between the non-display surface of the display screen assembly 20 and the front shell assembly 10; wherein, since the metal pressing plate 30 is provided with a screw fixing lug 303, when the display screen assembly 20 is fixedly pressed in the display screen mounting position 101, the metal pressing plate 30 and the front shell assembly 10 can be fixedly connected by screwing, and since the display screen assembly 20 is located between the front shell assembly 10 and the metal pressing plate 30, after the metal pressing plate 30 is fixedly connected with the front shell assembly 10, the display screen assembly 20 can be applied with a certain pressure by the metal pressing plate 30, thereby tightly attaching the display screen assembly 20 to the front shell assembly 10. In this way, the gap between the display screen assembly 20 and the front shell assembly 10 can be relatively sealed, thereby avoiding liquid, gas or dust from entering the inside of the display screen through the gap between the display window 1011 and the display screen assembly 20 and the front shell assembly 10, thereby playing a certain waterproof and dustproof role, and further protecting the display screen assembly 20 and other circuit components in the display screen, with good sealing effect and convenient installation.

[0050] As shown in the figure, Figures 3 to 5 , the metal pressing plate 30 comprises a main pressing frame 301 and a bent edge 302, the area formed by the first direction x and the second direction y of the main pressing frame 301 is adapted to the area formed by the first direction x and the second direction y of the display screen assembly 20, and the bent edge 302 is located around the main pressing frame 301 to surround the display screen assembly 20.

[0051] As shown in the figure, Figures 3 to 5As shown in FIG. 1, the size of the metal pressing plate 30 is adapted to the display screen assembly 20. After the display screen assembly 20 is fixed by the metal pressing plate 30, the four walls of the display screen assembly 20 can be tightly attached to the bent edges 302 of the metal pressing plate 30, so as to avoid loosening of the display screen assembly 20. The display screen assembly 20 can be tightly pressed on the front shell assembly 10 by the main pressing frame 301, so that the display screen assembly 20 can be tightly pressed and fixed after installation, and a better installation effect can be achieved. The main pressing frame 301, the bent edges 302 and the screw fixing ears 303 can be respectively formed by cutting and bending a metal sheet. In this way, the processing technology is relatively simple, and the production cost of the metal pressing plate 30 is saved. Moreover, the overall structure of the metal pressing plate 30 is more solid.

[0052] Referring to Figure 5 , the screw fixing ears 303 are respectively provided with a plurality of screw fixing ears 303 around the main pressing frame 301. As shown in Figure 5 , each screw fixing ear 303 can be fixedly connected between the front shell assembly 10 by a locking screw. In this way, the fixing between the metal pressing plate 30 and the front shell assembly 10 is more firm. In addition, since the screw fixing ears 303 around the main pressing frame 301 are fixedly connected between the front shell assembly 10, the pressure applied by the metal pressing plate 30 to the display screen assembly 20 is more uniform. In this way, the display screen assembly 20 and the front shell assembly 10 can also be more tightly attached, further improving the waterproof level.

[0053] Referring to Figure 3 and Figure 4 , the waterproof display screen with convenient assembly further comprises an outer frame sealing member 50, the opposite positions of the front shell assembly 10 and the rear shell assembly 40 are provided with sealing grooves 102, and the outer frame sealing member 50 is arranged in the sealing grooves 102 to seal the gap between the front shell assembly 10 and the rear shell assembly 40.

[0054] As shown in Figure 3 and Figure 4 , the outer frame sealing member 50 is arranged between the front shell assembly 10 and the rear shell assembly 40. After the front shell assembly 10 and the rear shell assembly 40 are fixed by screw locking, the front shell assembly 10 and the rear shell assembly 40 can tightly press the outer frame sealing member 50. In this way, the outer frame sealing member 50 arranged between the front shell assembly 10 and the rear shell assembly 40 can seal the gap between the front shell assembly 10 and the rear shell assembly 40, further improving the waterproof level.

[0055] Referring to Figures 2 to 5The easily assembled waterproof display screen further includes a circuit board 60, which is mounted between the metal pressure plate 30 and the rear shell assembly 40.
