[0032] Reference Figure 2 The inside of sleeve 2 is provided with threaded hole one 7 for penetrating bolt one 5, which is used in cooperation with bolt one 5.

[0033] Reference Figure 3 Threaded hole one 7 and bolt one 5 are connected with each other, threaded connection makes bolt one 5 move in threaded hole one 7 while rotating.

[0034] Reference Figure 4The fixing block 9 has a threaded hole 13 inside for use with bolt 11. The bolt 11 is used in conjunction with the threaded hole 13.

[0035] refer to Figure 4 The threaded hole 13 and the bolt 11 are connected by threads. The threaded connection allows the bolt 11 to move progressively inside the threaded hole 13 while rotating.

[0036] refer to Figure 1 A knob 10 is fixedly installed on the other end of bolt 2 11, which facilitates the rotation of bolt 2 11.

[0037] refer to Figure 4 A contact layer 14 is fixedly bonded to one side of the movable block 12, and an inner block 16 is fixedly bonded to the inside of the main pipe 1 between the two sealing rings 8.

[0038] Brief description of usage: When using the sintering low-oxygen-concentration leak-proof structure, when installing leak-proof installation on two adjacent pipes, the sleeve 2 can be first fitted onto the surface of the external pipe to be connected. Adjust the sleeve 2 to the appropriate position on the surface of the external pipe, and then rotate the knob 4 to drive the bolt 5 to rotate. The threaded connection allows the bolt 5 to move progressively inside the threaded hole 7 while rotating. The bolt 5 will drive the contact block 6 to make contact friction with the external pipe, thereby achieving a tight and limited connection between the sleeve 2 and the external pipe. Then, insert one end of the external pipe into the cavity 15, and first rotate the moving block 12 through the bearing to avoid the moving block 12 affecting or resisting the fixing ring 3. Since the main pipe 1 has an inclined design, external pipes of different diameters can be inserted into the main pipe 1 to different depths. After one end of the external pipe contacts the sealing ring 8, the bolt 11 will be driven by rotating the knob 10. The threaded connection allows bolt 11 to move progressively within the threaded hole 13 as it rotates. Bolt 11 then moves the moving block 12, ultimately bringing the contact layer 14 into contact with the retaining ring 3. During continuous tightening, the moving block 12 drives the external pipe deeper into the cavity 15 until one end of the external pipe makes tight contact with the sealing ring 8. This design allows for automatic adjustment of the seal's tightness based on sintering conditions via the rotation of knob 10, maintaining a stable seal over a long period. Furthermore, the sleeve 2 and knob 4 allow for the use of external pipes of different diameters, increasing the flexibility and compatibility of the structure.
