[0030] Example: See Figures 1 to 10 A special sealing device includes a base plate 3 and a positioning frame 2 vertically fixed to the middle of one side of the base plate 3 by bolts. The upper end of the positioning frame 2 has a through-hole. A first telescopic rod 1 is horizontally fixed on the positioning frame 2 on one side of the through-hole. The telescopic end of the first telescopic rod 1 passes through the positioning frame 2 and is engaged in a locking groove 24 opened at one end of a moving plate 8. A sliding mechanism is installed in the middle of the lower end of the moving plate 8, and a buffer mechanism and a workpiece bottom sealing mechanism are installed in the upper end of the moving plate 8. A positioning mechanism is installed in the upper end of the buffer mechanism. A detection mechanism is installed in one end of the base plate 3. The moving plate 8 and the first telescopic rod 1 facilitate the horizontal movement of the moving plate 8 in the device. The sliding mechanism includes a moving guide rail 7 horizontally fixed to the middle of the upper end of the base plate 3. Connecting rods are vertically fixed to both sides of the lower end of the moving plate 8 above the moving guide rail 7. The other end of the connecting rod is horizontally fixed to a limiting rod 6. The moving guide rail 7 and the limiting rod 6 facilitate the prevention of the moving plate 8 from disengaging from the moving guide rail 7 during the sliding process, thereby improving the stability of the sliding.

[0031] In this utility model, positioning plates 9 are bolted to all four sides of the upper end of the movable plate 8, and a buffer 5 is horizontally installed at one end of the movable plate 8. The buffer 5 is fixedly installed on the upper end of the buffer frame 4, and the buffer frame 4 is bolted to both sides of one end of the base plate 3.

The buffer mechanism includes a buffer post 35 fixedly installed in the middle of the upper end of the positioning plate 9. A first telescopic spring 29 is sleeved on the outside of the buffer post 35, and the upper end of the buffer post 35 is sleeved in the buffer holes opened around the lower ends of the support plate 10 and the support plate 11. The punch 35 and the first telescopic spring 29 facilitate the buffering of downward pressure to prevent the workpiece 13 from being squeezed and deformed. The sealing mechanism includes a sealing column that is bolted to the inner side of the positioning plates 9 on both sides of the upper end of the moving plate 8. A barrier plate 32 is fixed to the outer side of the sealing column. The barrier plate 32 has buffer holes that are equidistantly arranged vertically in a ring. Buffer rods 30 are installed at equal intervals in the buffer holes. A second telescopic spring 31 is sleeved between the sealing plate 34 and the barrier plate 32 on the outer side of the buffer rod 30. The sealing plate 34 is installed in the closed hole opened at the upper end of the support plate 11.

[0032] In this utility model, the support plate 11 is fixedly connected to the support plate 10. The holes on the support plate 10 and the support plate 11 are interconnected. The support plate 11 has positioning holes at equal intervals around its upper end, and a positioning snap-fit ​​hole is provided in the middle of the support plate 11.

[0033] In this invention, the testing mechanism includes four positioning posts 15 fixed vertically to one end of the base plate 3. A top plate 16 is fixed to the upper end of each positioning post 15. Guide rods 17 are equidistantly installed around the upper perimeter of the top plate 16, and a cylinder 18 is installed in the center of the top plate 16. The telescopic ends of the cylinder 18 and the guide rods 17 both penetrate the top plate 16 and are engaged with the upper testing template 22. The telescopic ends of the guide rods 17 are sleeved inside the positioning cylinder 26, which is fixed to the upper end of the testing template 22. Multiple positioning rods 25 are equidistantly fixed to the lower end of the testing template 22, and two airtight clamping heads 28 are fixedly installed on one side of the lower end of the testing template 22. Each airtight clamping head 28 has a horizontally fixed air inlet 27 at its upper end. The airtight clamping head 28 and the cylinder 18 facilitate the airtight clamping head 28 to fit tightly against one end of the workpiece 13 for sealing testing. The other end of the base plate 3 has fixed plates 14 bolted to both sides of the moving guide rail 7. A snap-fit ​​plate is vertically fixed to the middle of the other end of the base plate 3. A connecting plate 19 is horizontally fixed to the upper end of the snap-fit ​​plate. A triangular reinforcing rib 23 is fixed between the snap-fit ​​plate and the connecting plate 19. A second telescopic rod 20 is horizontally installed on the upper end of the connecting plate 19. A limit plate 21 is installed at the telescopic end of the second telescopic rod 20. The second telescopic rod 20 and the limit plate 21 facilitate the position determination of the workpiece 13 and prevent leakage due to inaccurate position during testing.

[0034] Working principle: In this embodiment, the present invention also proposes a method for using a special sealing device, including the following steps:

[0035] Step 1: First, place the workpiece 13 to be tested on the support plate 11. Then, use the limiting block 12 and guide post 33 to fix the position of the workpiece 13 and prevent inaccurate placement. Then, use the positioning frame 2 to determine the horizontal height of the first telescopic rod 1. Then, use the first telescopic rod 1 and the snap-fit ​​groove 24 to snap the telescopic end of the first telescopic rod 1 into the snap-fit ​​groove 24 at one end of the moving plate 8, so that the moving plate 8 can move horizontally on the moving guide rail 7 on the base plate 3, thereby pushing the workpiece 13 into the special sealing device. Then, use the snap-fit ​​plate and connecting plate 19 to prevent excessive pushing distance and push the moving plate 8 out of the special sealing device.

[0036] Step two: In order to ensure that the workpiece 13 to be tested is in the same vertical direction as the special sealing device, the second telescopic rod 20 and the limiting plate 21 are used to further fix the workpiece 13 to be tested. The limiting plate 21 can prevent the workpiece 13 from popping up during testing or the testing position from being inaccurate. The triangular reinforcing rib 23 strengthens the structure. Then, the positioning column 15 and the top plate 16 are used to make the cylinder 18 control the test template 22 to move downward. Then, the guide rod 17 and the positioning cylinder 26 are used to prevent the test template 22 from rotating during the pressing process. Finally, the positioning rod 25 is used to press the workpiece 13 to be tested.

[0037] Step 3: After determining the position of the workpiece 13 to be tested, the airtight clamping head 28 and the sealing plate 34 will be tightly fitted to both sides of the workpiece 13. Then, the buffer rod 30 and the second telescopic spring 31 will ensure that the sealing plate 34 is tightly fitted to the workpiece 13 to prevent leakage. Then, the buffer column 35 and the first telescopic spring 29 will prevent the support plate 11 and the support plate 10 from moving downwards simultaneously when the cylinder 18 moves downwards, effectively preventing the workpiece 13 from deforming due to compression. The limit rod 6 and the fixed plate 14 will prevent the moving plate 8 from putting pressure on the moving guide rail 7 during the downward press, which could damage the moving guide rail 7. Then, the air inlet 27 will allow gas to be injected into the workpiece 13 to perform a sealing test. After the test is completed, the cylinder 18 will retract, and the first telescopic rod 1 will retract to move the moving plate 8. Then, the buffer 5 and the buffer frame 4 will prevent the moving plate 8 from bumping during movement.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
