[0018] Figure 4 is Figure 1 a schematic structural diagram of the sealing strip in FIG. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the utility model with reference to specific drawings.

[0020] Specifically, as Figures 1 to 4 shown, a waterproof and dustproof structure of a panel lamp frame is provided, including a cover plate 10, a frame 20 connected to the cover plate 10, a diffusion plate 30 installed on the frame 20, and a sealing strip 40 arranged between the diffusion plate 30 and the cover plate 10.

[0021] As Figure 1 shown, the sealing strip 40 is installed in the panel lamp structure, and the sealing strip 40 has a sealing effect, which can effectively prevent water vapor and dust from entering the interior of the panel lamp through the gaps between the frame 20 and the cover plate 10 and the diffusion plate 30, improving the service life of the panel lamp.

[0022] Furthermore, the cover plate 10 includes a cover head 11, a cover edge 12 arranged around the cover head 11, and a resisting member 13 arranged at the lower end of the cover edge 12.

[0023] As Figure 1 and Figure 2 shown, the cover edge 12 is connected to the frame 20 by self-tapping screws. At this time, the resisting member 13 is buckled inside the frame 20 and connected to the sealing strip 40; the sealing strip 40 is in extrusion contact with the resisting member 13, blocking the gap between the frame 20 and the cover plate 10, so that water vapor and dust cannot enter the panel lamp through the gap between the frame 20 and the cover plate 10.

[0024] Further, the frame 20 includes a bottom edge 21, a hollow L-shaped frame 22 disposed on one side of the bottom edge 21, and a vertical edge 23 disposed on one side of the hollow L-shaped frame 22; the vertical edge 23 is disposed on the bottom edge 21 and forms a card slot 24 with one side of the hollow L-shaped frame 22.

[0025] Further, a pair of clamping heads 241 are provided on both sides of the card slot 24.

[0026] As Figures 1 to 3 shown, the sealing strip 40 is connected to the frame 20 by being embedded in the card slot 24.

[0027] Further, the sealing strip 40 includes a lower edge 41, a folded edge 42 connected to the lower edge 41, an upper edge 43 connected to the folded edge 42, and a plug 44 disposed below the upper edge 43; the sealing strip 40 is connected to the frame 20 by inserting the plug 44 into the card slot 24.

[0028] Further, a pair of clamping openings 441 are provided on both sides of the plug 44.

[0029] As Figures 1 to 4 shown, the sealing strip 40 is in pressing contact with the resisting member 13 through the upper edge 43. While generating pressure, an extrusion sealing effect is generated between the upper edge 43 and the resisting member 13, thereby preventing water vapor and dust from entering the panel lamp from the gap between the frame 20 and the cover plate 10.

[0030] Further, the card slot 24 is snapped into the clamping openings 441 through the clamping heads 241.

[0031] As Figures 1 to 4 shown, the sealing strip 40 is attached to the diffusion plate 30 through the lower edge 41. When the plug 44 is embedded in the card slot 24 and the card slot 24 is snapped into the clamping openings 441 through the clamping heads 241, a limiting operation is performed on the plug 44 to prevent the plug 44 from rebounding, and at the same time, an extrusion force is generated on the folded edge 42, and at the same time, the lower edge 41 generates an extrusion sealing effect on the diffusion plate 30, preventing water vapor and dust from entering from the seal between the frame 20 and the diffusion plate 30.
