[0010] Furthermore, the fastening assembly includes a first flange and a joint rotatably connected to the first flange, the first flange being fitted onto the circumferential surface of the pipe body, and the joint being threadedly connected to the threaded sleeve.
[0011] Furthermore, the connecting assembly includes a round tube and a pressing rod slidably connected inside the round tube. A compression spring is fixedly connected between the pressing rod and the round tube. Two slots are formed on the circumference of the pressing rod. An abutment rod is rotatably connected inside the slot. A spring is fixedly connected between the abutment rod and the slot. A nut is threaded onto the circumference of the round tube.
[0012] Furthermore, a second flange is fixedly connected to the circumference of the pipe body, the first flange and the second flange are fitted together, the round pipe passes through the first flange and the second flange, the abutting rod abuts against the first flange, and the nut abuts against the second flange.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-3 A gas pipeline reinforcement and connection device includes two pipeline bodies 1, and a connection device 2 for connecting the two pipeline bodies 1 is provided between the two pipeline bodies 1. The connection device 2 is fixed to the pipeline body 1 by a fixing component 3.
[0021] The connecting device 2 includes a connecting component 4 and two fastening components 5. The connecting component 4 is disposed between the two pipe bodies 1, and the two fastening components 5 are respectively disposed on the circumferential surfaces of the two pipe bodies 1.
[0022] It should be noted that the connecting assembly 4 includes a threaded sleeve 41 and an inner sleeve 42. A ring 43 is fixedly connected to the middle of the threaded sleeve 41 and the inner sleeve 42. A sealing ring 44 is provided on both sides of the ring 43. The sealing ring 44 is slidably connected between the threaded sleeve 41 and the inner sleeve 42. The two pipe bodies 1 are inserted into the threaded sleeve 41 and come into contact with the sealing ring 44 to achieve a seal.
[0023] In this embodiment, the fastening assembly 5 includes a first flange 51 and a connector 52 rotatably connected to the first flange 51. The first flange 51 is sleeved on the circumferential surface of the pipe body 1, and the connector 52 is threadedly connected to the threaded sleeve 41. The first flange 51 is attached to the second flange 11 through the fixing assembly 3, and then the pipe body 1 is inserted into the threaded sleeve 41. After that, the connector 52 is rotated to connect the two pipe bodies 1.
[0024] Furthermore, the fixing component 3 includes a round tube 31 and a pressing rod 32 slidably connected within the round tube 31. A compression spring 33 is fixedly connected between the pressing rod 32 and the round tube 31. Two slots 34 are formed on the circumference of the pressing rod 32. An abutment rod 35 is rotatably connected within the slots 34. A spring 36 is fixedly connected between the abutment rod 35 and the slots 34. A nut 37 is threaded onto the circumference of the round tube 31. Pressing the pressing rod 32 causes the abutment rod 35 to retract into the slots 34. Then, the round tube 31 is placed into the pre-drilled holes on the first flange 51 and the second flange 11. Then, the pressing rod 32 is released, causing it to pop out through the compression spring 33. Then, the abutment rod 35 pops out through the spring 36, thus abutting against the first flange 51. Finally, the nut 37 is rotated to lock the nut 37 against the second flange 11.
[0025] The pipe body 1 is fixedly connected to a second flange 11 on its circumference. The first flange 51 is fitted with the second flange 11. The round pipe passes through the first flange 51 and the second flange 11. The abutting rod 35 abuts against the first flange 51. The nut 37 abuts against the second flange 11.
[0026] Based on the above embodiment, the two pipe bodies 1 are movably inserted into the threaded sleeve 41, and the two pipe bodies 1 respectively abut against the two sealing rings 44.
[0027] Working method: During operation, the first flange 51 is attached to the second flange 11 via the fixing component 3. Then, the pipe body 1 is inserted into the threaded sleeve 41. After that, the joint 52 is rotated to connect the two pipe bodies 1. Then, the pressing rod 32 is pressed to retract the abutment rod 35 into the slot 34. Then, the round pipe 31 is placed into the reserved hole on the first flange 51 and the second flange 11. Then, the pressing rod 32 is released to allow the pressing rod 32 to pop out through the compression spring 33. Then, the abutment rod 35 pops out through the spring 36 to abut against the first flange 51. Finally, the nut 37 is rotated to lock the nut 37 against the second flange 11.
[0028] 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.
