Rapid cooling device of ion nitriding furnace

The utility model provides a rapid cooling device of an ion nitriding furnace, and belongs to the technical field of ion nitriding furnaces. The rapid cooling device of the ion nitriding furnace comprises the sealing assembly and the connecting assembly, firstly, cooling liquid enters the connecting hole and then applies pressure to the elastic plate to move downwards, the cooling liquid in the connecting hole enters the assembling plate, due to elastic reset of the elastic plate and sealing of the connecting hole by the sealing plate, the subsequent leakage phenomenon is avoided, and the service life of the cooling liquid is prolonged. The electric push rod is arranged on one side of the elastic plate, the sealing plate is fixedly connected with the electric push rod and makes contact with the elastic plate, the sealing plate is driven by the electric push rod to move, the sealing plate is made to be away from the through hole, then a small amount of cooling liquid in the connecting hole can flow into the as
