A second protective sleeve 4 is placed at one end of the first protective sleeve 3. Second fixing strips 6 are fixedly connected to both sides of the second protective sleeve 4. First fixing strips 5 are fixedly connected to both sides of the first protective sleeve 3. One side of each first fixing strip 5 is open. A positioning groove 11 is provided, and a positioning block 10 is fixedly connected to one side of the second fixing strip 6. One end of the positioning block 10 extends into the positioning groove 11. Two first sealing half gaskets 16 are fixedly connected inside the second protective sleeve 4, and two second sealing half gaskets 17 are fixedly connected to the inside of the first protective sleeve 3. The two first sealing half gaskets 16 and the second sealing half gaskets 17 form two sealing components. One first sealing half gasket 16 and one second sealing half gasket 17 cooperate with each other. The inner diameter of the two sets of sealing components are respectively matched with the outer diameter of the threaded connection end 21 and the pipe joint 2.

[0023] A sealing sheet is placed between the first protective sleeve 3 and the second protective sleeve 4 to seal the space between them.

[0024] A drive box 7 is fixedly connected to one side of the first fixed bar 5, a connecting post 19 is fixedly connected to one side of the drive box 7, and a protective box 15 is fixedly connected to one end of the connecting post 19, so that the two protective boxes 15 are located on both sides of the monitor 1, so as to drive the worm gear 13 to rotate.

[0025] The drive box 7 is rotatably connected to a sliding screw 8. The outer side of the sliding screw 8 is threaded with a plug 9. A slot 18 is provided on one side of the first fixing bar 5. One end of the plug 9 passes through the slot 18 and is inserted into the positioning block 10. The positioning block 10 limits the first fixing bar 5 and the second fixing bar 6.

[0026] One end of the sliding lead screw 8 passes through the connecting post 19 and extends into the protective box 15, where a worm wheel 12 is fixedly fitted. Inside the protective box 15, a worm 13 is rotatably connected. The worm 13 is connected to the worm wheel 12 for transmission. The sliding lead screw 8 is driven to rotate through the worm 13 and the worm wheel 12, which in turn drives the insertion post 9 to move.

[0027] Example 2

[0028] Please see Figure 1 and Figure 2 The present invention provides a technical solution: a sealing plate 20 is hinged to the top of the protective box 15, and magnetic blocks 14 that attract each other are fixedly connected to the bottom of the sealing plate 20 and the top of the protective box 15. The sealing plate 20 is limited to the top of the protective box 15 by the magnetic attraction between the two magnetic blocks 14.

[0029] In summary, when using this gas pipeline pressure monitoring device, the monitor 1 is connected to the pipe joint 2 via the threaded connection end 21. Then, the first protective sleeve 3 and the second protective sleeve 4 are placed outside the pipe joint 2 and the threaded connection end 21, so that the positioning block 10 is located inside the positioning groove 11. Then, the sealing plate 20 is opened, and the worm gear 13 is rotated, so that the worm gear 13 drives the worm wheel 12 to rotate, so that the worm wheel 12 drives the sliding screw 8 to rotate, so that the sliding screw 8 drives the insertion post 9 to move, so that one end of the insertion post 9 is inserted into the positioning block 10 through the slot 18, fixing the first fixing strip 5 and the second fixing strip 6, thereby fixing the second protective sleeve 4 and the first protective sleeve 3. The first sealing half gasket 16 and the second sealing half gasket 17 in the two sets of sealing components protect the joint between the threaded connection end 21 and the pipe joint 2.

[0030] When it is necessary to disassemble the monitor 1, the worm gear 13 drives the worm wheel 12 to reset and rotate, so that the worm wheel 12 drives the sliding screw 8 to reset and rotate, so that the sliding screw 8 drives the pin 9 to reset and move, so that one end of the pin 9 moves through the slot 18 into the drive box 7. Then, the first fixing strip 5 and the second fixing strip 6, as well as the first protective sleeve 3 and the second protective sleeve 4 are separated, so that the first protective sleeve 3 and the second protective sleeve 4 are removed from the outside of the threaded connection end 21 and the pipe joint 2. Then, the bottom end of the threaded connection end 21 is screwed out of the pipe joint 2.
