[0027] According to an embodiment of the present invention, a locking mechanism for breathable bricks is provided.
[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, a locking mechanism for a breathable brick according to an embodiment of the present invention includes a gas guide pipe 2 and an argon gas inlet pipe 9. One end of the gas guide pipe 2 is fixedly connected to the breathable brick body 1, which is a common structure in the art. The other end of the gas guide pipe 2 is threaded with a sleeve 4, and one end of the sleeve 4 is fixedly connected to a first connecting plate 3. A central hole is opened at the center of the first connecting plate 3, and an insertion hole 6 is opened through the outer side of the central hole on the surface of the first connecting plate 3. Multiple sets of insertion holes 6 are arranged. A docking ring 14 is fixedly installed on the other end of the first connecting plate 3 outside the central hole. The gas guide pipe 2 passes through the central hole. One end of the argon gas inlet pipe 9 is fixedly connected to a second connecting plate 8, and a post 7 is fixedly connected to the other side surface of the second connecting plate 8 at the position corresponding to the insertion hole 6. A side groove 16 is opened on one side surface of the other end of the post 7. A locking block 17 is slidably connected inside the side groove 16, and the locking block 17 is connected to the inner end surface of the side groove 16 by a spring 18. A ring seat 12 is fixedly connected to the other end surface of the second connecting plate 8 at the position corresponding to the docking ring 14. Furthermore, an annular groove 13 is provided at the other end of the ring seat 12, and an elastic sealing gasket 15 is fixedly bonded to the bottom surface of the annular groove 13. When the breathable brick body 1 is locked, the insertion hole 6 on the surface of the first connecting plate 3 at the other end of the air guide tube 2 can be aligned with the insertion post 7. Then, the air guide tube 2 is moved until the insertion post 7 passes through the insertion hole 6. During the process of the insertion post 7 passing through the insertion hole 6, the locking block 17 is squeezed and enters the side groove 16, and the spring 18 is compressed. Subsequently, the docking ring 14 is inserted into the annular groove 13, squeezing the elastic sealing gasket. 15. After the locking block 17 passes through the insertion hole 6, the spring 18 rebounds, pushing the locking block 17 outward to lock the first connecting plate 3, thus completing the locking. Since the docking ring 14 is pressed against the elastic sealing gasket 15 at this time, the first connecting plate 3 and the second connecting plate 8 cannot move or rotate axially, and can withstand greater tension and pressure, making the locking more stable and reliable. At the same time, after the docking ring 14 is pressed against the elastic sealing gasket 15, it seals the gas guide pipe 2 and the argon gas inlet pipe 9, resulting in better sealing effect and higher working stability.

The staff can rotate the gas guide pipe 2 to drive the external thread 5 to rotate, thereby finely adjusting the installation height of the gas guide pipe 2 and the gas-permeable brick body 1. The sealing ring 11 plays a sealing role, further improving the air tightness.
[0031] In one embodiment, the insertion column 7 is arranged in multiple groups, and the insertion column 7 is a rectangular column. The bottom opening of the insertion hole 6 is provided with a flared opening 10, and the opening size of the insertion hole 6 is equal to the vertical projection size of the insertion column 7, thereby avoiding shaking. The flared opening 10 facilitates the insertion of the insertion column 7 into the insertion hole 6.
[0032] In one embodiment, the spring 18 is fixedly connected with the clamping block 17 and the inner wall of the edge groove 16 at both ends, respectively, and the inclined surface of the clamping block 17 extends out of the opening of the edge groove 16. One end of the clamping block 17 is an inclined surface, which facilitates the clamping block 17 to enter the edge groove 16 after being pressed, and the spring 18 prevents the clamping block 17 from falling off.
[0033] In one embodiment, the sealing rings 11 are arranged in multiple groups at equal intervals, and the sealing rings 11 are made of a high-temperature-resistant structure. The sealing rings 11 can be made of a high-temperature-resistant rubber material, thereby improving the sealing performance in a high-temperature environment.
[0034] In one embodiment, the inner wall of the sleeve 4 is provided with an internal thread matched with the external thread 5, thereby facilitating the staff to rotate and adjust.
