The torque output end is connected to the horizontal connecting rod 32 in a transmission. The structure of the second reversing assembly 33 is the same as that of the reversing assembly 605, but the dimensions are different. The small sealed door leaves on the left and right sides of the second handwheel 30 3. One or more vertical connecting rods 34 in a vertical state with the horizontal connecting rod 32 are vertically arranged, and the horizontal connecting rod 32 is connected to the vertical connecting rod 32 through the second reversing assembly 33 respectively. The straight connecting rods 34 are connected in a driving manner. The first locking pin seats 35 are respectively arranged at the ends of the vertical connecting rods 34. One end of the first locking pin 36 in each first locking pin seat 35 protrudes out. The other ends of the first lock pins 36 in each of the first lock pin seats 35 pass through the first lock pin seats 35 and are respectively fixedly connected with the vertical links 34 on the corresponding side. After the pin seat 35 is extended, it is inserted into the locking seat on the door frame 1 and the large sealed door leaf 2, thereby realizing the closing of the small sealed door leaf 3. When the second hand wheel 30 is rotated, the second worm gear reduction mechanism 31 (turbine reducer) ) Drive the horizontal connecting rod 32 to slide to the left, the horizontal connecting rod 32 drives the second reversing assembly 33 to rotate, thereby driving the first locking pin seat 35 connected with the vertical connecting rod 34 to leave the locking seat on the door frame 1 and the large sealing door leaf 2 , so that the small sealed door leaf 3 can be pushed inward or outward (same or opposite to the opening direction of the large sealed door leaf 2), thereby realizing the unlocking operation.
