The sealing head 7 can be used to seal the test hole of the airtight test part, thereby performing an airtight test on the part.
[0032] Specifically, the elastic mechanism is arranged on the guide rod cylinder 2, and the elastic mechanism includes a spring seat 3, a spring 4, a guide shaft 5 and a spring seat 2 6. The spring seat 3 is detachably connected to the guide rod cylinder 2. Four guide shafts 5 are provided. The four guide shafts 5 can be detachably connected to the bottom of the spring seat 3, and the four guide shafts 5 are symmetrically arranged. The spring seat 2 6 is slidably sleeved on the four guide shafts 5. Four springs 4 are provided. The four springs 4 are fixedly connected between the spring seat 3 and the spring seat 2 6, and the four springs 4 are respectively sleeved on the four guide shafts 5.
[0033] In a specific embodiment of the utility model, the spring seat 3 is configured to connect two guide shafts 5, and the two guide shafts 5 are configured to slidably sleeve the spring seat 26. The spring seat 26 is slidably sleeved on the two guide shafts 5, so that the spring seat 26 can slide on the two guide shafts 5. The two springs 4 are configured to limit the sliding of the spring seat 26 on the guide shaft 5. The spring 4 can be compressed by the sliding of the spring seat 26 on the guide shaft 5. The spring 4 can be configured to restore the moved spring seat 26 to its initial position.
[0034] Specifically, a sealing mechanism is disposed on the plugging head 7, and the sealing mechanism is used to improve the sealing performance of the airtight test. The sealing mechanism includes a sealing gasket pressure ring 8 and a sealing gasket 9. The sealing gasket 9 is movably sleeved on the bottom of the plugging head 7, the sealing gasket pressure ring 8 is fixedly connected to the bottom of the plugging head 7, and the sealing gasket pressure ring 8 is movably sleeved on the sealing gasket 9.
[0035] In a specific embodiment of the present utility model, the sealing gasket pressure ring 8 is used to connect the sealing gasket 9. The sealing gasket 9 can improve the sealing performance of the floating plugging head and improve the accuracy of the airtight test.
[0036] Specifically, the guide rod cylinder 2 is detachably connected to one side end of the blocking cylinder mounting plate 1 by means of screws.
[0037] In a specific embodiment of the utility model, the guide rod cylinder 2 is detachably connected to one side end of the blocking cylinder mounting plate 1 by means of screws, so that the guide rod cylinder 2 is easy to install and disassemble.
[0038] Specifically, the plugging head 7 is detachably connected to the bottom of the spring seat 2 6 by means of screws.
[0039] In a specific embodiment of the present utility model, the plugging head 7 is detachably connected to the bottom of the spring seat 2 6 by screws, so that the plugging head 7 is easy to install and disassemble.
[0040] Specifically, the spring seat 3 is detachably connected to the extended end of the guide rod cylinder 2 by means of screws, and each guide shaft 5 is detachably connected to the bottom of the spring seat 3 by means of screws.

[0042] The working principle or working process of the floating sealing head for airtight test provided by the utility model is as follows: the extension of the extended end of the guide rod cylinder 2 can drive the spring seat 3 to descend, the descent of the spring seat 3 drives the spring seat 26 to descend, the descent of the spring seat 26 drives the sealing head 7 to descend, and after the sealing head 7 is descended, it is pressed on the airtight test part, and the sealing gasket 9 can improve the sealing effect. After the sealing head 7 is against the airtight test part, the spring seat 3 continues to move to drive the guide shaft 5 to move, so that the guide shaft 5 moves on the spring seat 26. After the spring seat 3 moves, the spring 4 is compressed, so that the spring 4 is compressed to generate a compression elastic force. When the sealing head 7 is removed from the airtight test part, the compression elastic force of the spring 4 pushes the spring seat 26 to move, so that the spring seat 26 slides on the guide shaft 15, thereby restoring the spring seat 26 to its initial position.
