Description

Technical Field

[0001] The utility model relates to the technical field of hollow plastic plates, in particular to a flame-retardant hollow plastic plate. Background Art

[0002] Hollow plastic board, also known as plastic middle board, is a new type of material that is light in weight, non-toxic, pollution-free, waterproof, shockproof, anti-aging, corrosion-resistant, and colorful. Compared with cardboard structural products, hollow board has the advantages of moisture-proof, corrosion-resistant, and lighter to replace cardboard. Compared with injection molding products, hollow board has the advantages of shockproof, flexible structural design, and no need to open injection molds.

[0003] After searching, a Chinese patent with announcement number CN216195951U is disclosed, which discloses a flame-retardant hollow plastic plate. Threaded holes are provided on the upper surfaces of the first hollow plate and the second hollow plate, and the first connecting plate can fix the position of the first hollow plate and the second hollow plate through the cooperation of locking bolts and threaded holes, which is convenient for splicing to increase the usable area. When a fire occurs, the water pipe is connected to the water inlet, and water spray outlets are provided on both sides of the middle connecting frame. The fire is extinguished inside the water inlet. The inside of the water inlet is provided with an internal thread. When it is not needed, the water inlet is closed with a closing cover to prevent impurities from entering.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. The upper and lower hollow panels can only be connected by a connecting plate. When multiple hollow panels are spliced, the water inlet holes and the water spray holes cannot be connected. Multiple water pipes are required for connection, which is costly and seriously affects the flame retardant effect, reducing the flame retardant efficiency of the hollow plastic board.
