Waterproof structure of aluminum profile

The utility model relates to the technical field of aluminum profiles, in particular to a waterproof structure of an aluminum profile. The device comprises a pair of aluminum profile plates, fixing blocks are fixedly connected to the two sides of one aluminum profile plate, a sliding block is fixedly connected to the upper surface of the fixing block on one side, limiting plates are fixedly connected to the two sides of the sliding block, and a sliding groove matched with the sliding block is formed in the lower surface of the fixing block on the other side; limiting grooves matched with the limiting plates are formed in the two side walls of the sliding groove correspondingly, sealing plates are arranged on the upper sides of the pair of fixing blocks on the same side, threaded holes are formed in the two sides of the upper surfaces of the sealing plates, and threaded grooves matched with bolts are formed in the fixing blocks. The problems that water permeates into the aluminum profile through gaps generated
