[0032] See Figures 1 to 8As shown, in one embodiment of this utility model, a front frame assembly 1000 includes: a frame 100, the frame 100 having a front and a back side facing away from each other, the back side of the frame 100 being used to mount a rear frame assembly 3000, and a sealing gasket 200 being mounted on the front side of the frame 100; a module fixing plate 300, the module fixing plate 300 and the frame 100 clamping the sealing gasket 200, the module fixing plate 300 being used to mount a display module 4000; and a pressure ring 400, the pressure ring 400 being disposed on the surface of the module fixing plate 300 away from the sealing gasket 200, so that the module fixing plate 300, the sealing gasket 200 and the frame 100 are tightly fitted together.

[0033] In the technical solution of this utility model, when applied to the cabinet of a profile screen, the frame 100 has a front and a back side facing each other. A rear frame assembly 3000 is installed on the back side of the frame 100, and a sealing gasket 200 is installed on the front side of the frame 100. The module fixing plate 300 and the frame 100 sandwich the sealing gasket 200. The module fixing plate 300 is used to install the display module 4000. The pressure ring 400 is pressed on the surface of the module fixing plate 300 away from the sealing gasket 200, so that the module fixing plate 300, the sealing gasket 200 and the frame 100 are tightly fitted. In this way, the sealing gasket 200 achieves a stable seal between the installation gap between the module fixing plate 300 and the frame 100, avoiding problems such as poor sealing caused by adhesive layer cracking, and ensuring the waterproof function of the profile screen.

[0034] It should be noted that in this embodiment, the edge of the module fixing plate 300 is attached to the sealing gasket 200, and the display module 4000 is disposed on the surface of the module fixing plate 300 opposite to the sealing gasket 200.

It should be noted that in this embodiment, the frame 100 includes multiple retaining strips 120, which are connected end-to-end to form a frame-like structure. Each retaining strip 120 protrudes from an inner wall of the frame body 110. This embodiment is not limited to this, and all of the above are within the protection scope of this embodiment. The frame 110 of this utility model has a groove 110a, a sealing gasket 200 is disposed in the groove 110a, and a retaining strip 120 is recessed within the end face of the frame 110. The retaining strip 120 positions the installation of the module fixing plate 300 so that the display module 4000 is installed on the module fixing plate 300 and flush with the end face of the frame 100, ensuring the overall aesthetics of the profile screen. Furthermore, in this embodiment, the module fixing plate 300 extends into the frame 100 and presses the sealing gasket 200 within the groove 110a, thereby further reducing the width of the frame 100, which helps to achieve a narrow bezel effect. This reduces the amount of material used in the frame 100, thus lowering production costs, while maintaining the overall aesthetics of the profile screen. This embodiment achieves a stable seal between the module fixing plate 300 and the frame 100, reducing the production cost of the profile screen and ensuring its overall aesthetics.

[0036] See Figures 1 to 8 As shown, in one embodiment of this utility model, the frame 110 includes a plurality of profiles 111 connected end to end in sequence. Each profile 111 forms a cavity 111a. The sidewall of the cavity 111a is recessed to form a groove 110a. A hook 130 protrudes from the sidewall of the cavity 111a opposite to the groove 110a, engaging with the rear frame assembly 3000.

The outer cover 101 recesses into the shelf 102 to form a groove 110a, and a baffle 120 is provided on the surface of the shelf 102 facing away from the outer cover 101. It should be noted that in this embodiment, the outer cover 101 forms a cavity 111a to realize the installation of the module fixing plate 300 and the rear frame assembly 3000 on both sides, thereby ensuring the overall aesthetics of the profile screen. The shelf 102 seals the cavity 111a formed by the outer cover 101, which on the one hand prevents water flowing into the cavity 111a from flowing into the box, and on the other hand, the double-layer structure of the outer cover 101 and the shelf 102 isolates the electronic components inside the box, thereby achieving the effect of sun protection and heat insulation, and extending the service life of the profile screen.

[0038] See Figures 1 to 8 As shown, in one embodiment of this utility model, the cavities 111a of multiple profiles 111 are interconnected. A drainage hole 101a is provided on the profile 111 at the bottom of the frame 110 to allow water flowing into the cavity 111a to flow out through the drainage hole 101a. It should be noted that multiple drainage holes 101a are provided on the profile 111 at the bottom of the frame 110, and these drainage holes 101a are spaced apart on the bottom wall of the cavity 111a. Of course, in this embodiment, the size, shape, and spacing of the drainage holes 101a can be adjusted as needed. This embodiment is not limited to these limitations, and all of the above are within the protection scope of this utility model. In this embodiment, the cavities 111a of multiple profiles 111 are interconnected. Water inside these multiple profiles 111 flows to the bottom profile 111 under the action of gravity. The bottom profile 111 has a drainage hole 101a, so that water flows out through the drainage hole 101a of the bottom profile 111. This realizes the automatic drainage function of the box, avoids water entering the box, and ensures the waterproof function of the profile screen, thus meeting the functional requirements of the profile screen for outdoor installation.
