[0024] The leak detection mechanism 7 includes a lifting seat 701, a pressure head 702, a sealing plate 703, a first spring 704, a guide sleeve 705, a guide rod 706, a positioning rod 707, a second spring 708, and a guide hole 709. The lifting seat 701 is connected to the output end of the cylinder 1. The top of the interior of the lifting seat 701 is provided with multiple sets of pressure heads 702 and sealing plates 703. The bottom of the interior of the lifting seat 701 is provided with multiple sets of guide rods 706, and the outer sides of the guide rods 706 are respectively provided with guide sleeves 705 and springs that interact with the guide sleeves 705.

[0027] Working principle: This multi-station quick-change leak detection device;

[0028] When the device carries out leak detection work to the product, firstly, the product is sleeved with the sleeve ring 302, and the test pipe body 301 is inserted into the inner side of the connecting pipe 2 by using the sleeve ring 302, during which, after the sleeve ring 302 extends into the connecting pipe 2, the sleeve ring 302 is rotated to the specified position, the sleeve ring 302 drives the two groups of arc-shaped blocks 303 to contact and extrude the two groups of positioning rods 707, and the positioning rods 707 are retracted under the elastic compression of the second spring 708 and the guide hole 709, so that after the sleeve ring 302 is rotated to the specified position, the two groups of positioning rods 707 are automatically clamped into the inside of the positioning hole 304 under the elastic recovery force of the second spring 708, thereby assembling the test product body 3 on the inner side of the connecting pipe 2, so as to quickly disassemble and assemble the product, and the starting of the air cylinder 1 drives the air cylinder 1 to drive the leak detection mechanism 7 and the assembled product to press downwards, so that after the product contacts the air nozzle 4, the connecting pipe 2 is driven by the pressure to be elastically compressed outside the guide rod 706 and the first spring 704 by the two groups of guide sleeves 705, so that the product is extruded and contacted with the pressure head 702 and the sealing plate 703, thereby sealing the product under the pressure state, then the starting of the electromagnetic valve blows air to the product through the air nozzle 4, then the air is cut off to keep the pressure, and the pressure relief value in a certain time is tested under the detection of the pressure gauge 6, so as to complete the leak detection work to the product, and when disassembled again, the two groups of positioning holes 304 are only needed to be driven by the rotating knob test pipe body 301 to cancel the clamping fixation with the positioning rods 707 under the output state, so as to take out the product from the connecting pipe 2, which is convenient for quickly replacing the product, and the air nozzle 4 can be replaced, thereby realizing the leak detection to different specifications of products and improving the functionality of the leak detection device.
