[0024] Embodiment 2

[0025] Referring to Figures 1-4 , the second embodiment of the utility model, the present embodiment is based on the previous embodiment.

[0026] In the present embodiment, the outer frame 11 and the frame cover 12 are made of epoxy resin and glass fiber, and the paint 13 is water-based latex paint.

[0027] Screws 121 are movably connected to all four sides of one side of the paint 13, and screw holes 111 are opened on all four sides of one side of the outer frame 11. One end of the screw 121 extends into the inner cavity of the screw hole 111 and is threadedly connected to the inner cavity of the screw hole 111.

[0028] A limiting block 112 is fixedly connected to the top of the inner cavity of the outer frame 11. A groove is provided on the top of the plate 21. The limiting block 112 extends into the inner cavity of the groove and is movably connected to the inner cavity of the groove.

[0029] The plate 21 is located in the inner cavity of the outer frame 11 and is movably connected to the inner cavity of the outer frame 11. The side of the raw material plate 21 of the rubber pad 22 contacts the outer frame 11 and the frame cover 12 respectively.

[0030] like Figures 1-4 As shown, the outer frame 11 and frame cover 12 are made of epoxy resin and glass fiber, which can effectively improve their strength and hardness, thereby improving the compressive strength of the plate 21. The paint 13 is water-based latex paint, which can block external ultraviolet rays and improve the UV resistance of the plate 21. The frame cover 12 is moved to one side of the outer frame 11, and the screw 121 is aligned with the screw hole 111. The screw 121 is rotated. Since the screw 121 and the screw hole 111 are threaded, the screw 121 will gradually enter the inner cavity of the screw hole 111 during the rotation, thereby realizing the connection between the frame cover 12 and the outer frame 11, which facilitates the covering and protection of the plate 21. The limiting block 112 extends into the inner cavity of the groove, thereby limiting the plate 21 and preventing the plate 21 from shaking or misaligning.

[0031] In use, the hollow design of the panel 21 reduces its weight. The porous glass microspheres 23 inside the panel 21 have a low density, and their porous structure improves the sound insulation and heat preservation performance of the panel 21. Furthermore, the porous glass microspheres 23 possess thermal stability, allowing the panel 21 to maintain its structure and performance under high temperatures. The outer frame 11 and frame cover 12 protect the panel 21 from external pressure. When pressure is transmitted to the rubber pad 22, the pad buffers the pressure, further protecting the panel 21 and improving its compressive strength, preventing cracking under external pressure. The paint 13 applied to the surfaces of the outer frame 11 and frame cover 12 effectively blocks ultraviolet radiation, improving the panel 21's UV resistance and preventing aging caused by direct UV exposure, which could affect its service life and performance.
