Fixing device for grid plate

The fixing device for the grid plate comprises a grid plate body, flanges are fixedly connected to the two ends of the grid plate body respectively, a plurality of positioning grooves are formed in the connecting ends of the two flanges respectively, fixing grooves are formed in the inner walls of the positioning grooves respectively, and sealing plates are arranged on the sides, away from the grid plate body, of the two flanges respectively. And a plurality of fixing mechanisms are fixedly installed between the two sealing plates and the positioning groove, two pushing mechanisms are installed on one side of the outer surface of each sealing plate, and the four pushing mechanisms are connected with the multiple fixing mechanisms on the same side correspondingly. According to the sealing plate, the fixing groove, the positioning groove, the fixing mechanism and the pushing mechanism are arranged, an original bolt fixing structure is replaced, it is avoided that bolts are difficult to disassemble due to the ph
