[0021] A lifting rod 26 is fixedly connected to the top of the upper sealing plunger 43, the inside of the lifting rod 26 is threadedly connected to the lower part of the surface of the driving rod 4, a threaded groove 27 is opened on the lower part of the surface of the driving rod 4, a lifting slider 28 is fixedly connected to the top of the guide plate 8, and a limiting block 30 is fixedly connected to the lifting rod 26.

[0022] A limiting groove 29 is opened inside the lifting slider 28, and the limiting groove 29 is adapted to the limiting block 30. The limiting block 30 slides inside the limiting groove 29, which can prevent the lifting rod 26 from rotating when the driving rod 4 rotates.

[0026] The working principle of the airtightness detection device for the radiator provided by the present utility model is as follows:
[0027] When the device works, the radiator is placed vertically, and the bottom radiator port is sleeved into the lower sealing plunger 35. The motor 3 is started, and the driving rod 4 starts to rotate. Through the meshing relationship, the driving gear 25 drives the left gear 5 and the right gear 6 to rotate, driving the threaded rods 7 on the two gears to rotate, and then driving the threaded sliding sleeve 10 to move inward. The detection cylinder 12 is driven to move inward through the guiding slide rod 11. The radiator detection space is divided into a plurality of detection compartments 15 by the fin sealing ring 31. Gas enters the radiator from the air port 36. If there is air leakage, the gas will enter the detection tube 13, and the gas is guided to the detection mechanism 14 through the conical guide cylinder 21 and the guide tube 22. The air flow impacts the detection plate 20, and the pointer 19 is rotated through the detection shaft 18. The degree of air leakage is observed through the scale line 24. The device only needs to sleeve the radiator on the lower sealing plunger 35 to complete the feeding. By setting a plurality of detection compartments 15, the air leakage source of the radiator can be observed more intuitively, which is convenient for later maintenance.
