Louver blade, louver balde assembly and pergola

Abstract

The present application discloses a louver blade, a louver blade assembly, and a pergola. The louver blade comprises a louver blade body, wherein a first matching part and a second matching part are respectively provided on two long sides of the louver blade body. When a plurality of louver blade bodies are horizontally hinged and cooperate with each other, a louver blade body cooperates with a second mating part of an adjacent louver blade body through its first matching part, so that an overlapping sealing area is formed between two adjacent louver blade bodies, so that no gap fit can be realized, and the function of tight fit and shielding can be realized. Its waterproof and sunshade effect is good, and there is no seepage when draining.
