[0018] Combined with the attached Figures 1-4 The air volume regulating device at the air outlet of the toughening furnace air inlet box includes an air outlet plugging plate assembly arranged on the bottom plate of the air inlet box body 2 and a push-pull assembly for the air outlet plugging plate assembly. There are two identical groups of air outlet plugging plate assemblies, which are respectively located on both sides of the bottom plate of the air inlet box body 2. Any one group of air outlet plugging plate assemblies includes a plugging plate 7 and a sliding seat 8. The sliding seats 8 are fixed in two rows at intervals. The sliding seats 8 are all in an "L" shape. The plugging plate 7 is a "T" shaped plate, which is matched with the "L" shaped step surfaces of the two rows of sliding seats 8 and is slidably arranged. And the lower bottom surface of the plugging plate 7 is closely attached to the upper surface of the bottom plate of the air inlet box body 2. Air outlet holes 9 corresponding to several air outlets 6 on the bottom plate of the air inlet box body 2 are provided on the plugging plate 7; There are two groups of push-pull assemblies. One end of any one group is fixed on the plugging plate 7, and the other end is arranged outside the air inlet box body 2; Any one group of push-pull assemblies includes a fixed seat 3, a pull rod 4, a cylinder 5 and a flange seat 10. The flange seat 10 is in a horizontal "channel" shape. Both side walls of the flange seat 10 are fixed on the right end face of the air inlet box body 2. The cylinder 5 is fixed on the right end face of the flange seat 10 through a cylinder seat. The push rod of the cylinder 5 is fixedly connected with the right end of the pull rod 4 through a coupling 13. A fixed seat 3 is fixed in the middle of the upper right side of the plugging plate 7.
