[0017] See also Figure 1-5 The utility model provides a technical solution: a stainless steel seamless pipe with a sealing mechanism, comprising a steel pipe body 1, a connecting ring 2 is fixedly connected to the inner wall of one end of the steel pipe body 1, a sealing ring 3 is fixedly connected to the connecting ring 2, a connecting sleeve 4 is fixedly connected to the outer side of the other end of the steel pipe body 1, a limiting ring 5 is fixedly connected to the inner wall of the connecting sleeve 4, a symmetrical fixing groove 6 is fixedly connected to the outer side of the connecting sleeve 4, blocks 7 corresponding to the fixing groove 6 are slidably connected to the two sides of the connecting sleeve 4, the blocks 7 are slidably connected to the fixing groove 6, a fixing rod 8 passing through the fixing groove 6 is fixedly connected to the middle of one end of the block 7 close to the bottom end of the fixing groove 6, and a spherical block 9 is fixedly connected to the other end of the fixing rod 8.
[0018] Furthermore, the inner diameter and outer diameter of the connecting ring 2 and the limiting ring 5 are the same, so as to facilitate the connection of the two steel pipe bodies 1 .
[0019] Furthermore, the outer diameter of the sealing ring 3 is the same as the inner diameter of the connecting sleeve 4, so that the two steel pipe bodies 1 are in a sealed state when connected.
[0020] Further, the block 7 is arranged in a trapezoidal structure, the inclined surface of the block 7 faces the end of the connecting sleeve 4 away from the steel pipe body 1, the inclined surface part of the block 7 is located inside the connecting sleeve 4, and the other part of the block 7 is located inside the fixing groove 6. It is convenient for the block 7 to slide in the fixing groove 6 and to connect the two steel pipe bodies 1.
[0021] Furthermore, a return spring 10 is sleeved on the fixing rod 8, and the return spring 10 is located in the fixing groove 6, so as to facilitate the clamping and fixing of the two steel pipe bodies 1.
[0022] Specifically, when the utility model is used, the connecting ring 2 of one steel pipe body 1 is first moved into the connecting sleeve 4 of the other steel pipe body 1. During the movement, the sealing ring 3 will squeeze the block 7 in the direction of the reset spring 10, causing the reset spring 10 to shrink until the connecting ring 2 reaches the position of the limit ring 5. The sealing ring 3 reaches the other side of the block 7, and the reset spring 10 restores its elasticity, thereby restoring the block 7 to its initial position, so that the two steel pipe bodies 1 can be connected. The operation is simple and easy to use.
