[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the problem that the above-mentioned device connects the pipeline through two sleeve rings, but the above-mentioned device needs to screw multiple nuts to fix the fastening plate when fixing the pipeline. When the pipeline is maintained and disassembled, it is necessary to carry additional tools and screw multiple nuts for disassembly, which is a relatively inconvenient technical problem. The overall idea is as follows: A natural gas pipeline connection device includes a pipeline body 11, a card slot 12 is opened inside the pipeline body 11, and two rotating shafts 13 are rotatably connected inside the pipeline body 11. The two rotating shafts 1 The outer surfaces of the two connecting rods 14 are sleeved, and the opposite ends of the two connecting rods 14 are fixedly connected with a clamping block 15. The two clamping blocks 15 are adapted to the clamping groove 12. By connecting multiple pipeline bodies 11 to transport natural gas, when the pipeline bodies 11 are installed and connected, one section of the pipeline body 11 is inserted into another section of the pipeline body 11. When the pipeline body 11 is inserted, the clamping block 15 is squeezed to make the connecting rod 14 rotate with the rotating shaft 13 as the axis, and the pipeline body 11 is fixed and limited by the clamping block 15 connected to the connecting rod 14 being clamped in the clamping groove 12.

[0029] The outer surface of the pipe body 11 is sleeved with a quick release mechanism, which includes a spring 16, which is sleeved on the outer surface of the pipe body 11, and a sleeve 17 is sleeved on the outer surface of the spring 16. The sleeve 17 is slidably connected to the outer surface of the pipe body 11, and an extrusion ring 18 is fixedly connected to the inner surface of the sleeve 17. A connecting block 19 is fixedly connected to the outer surface of the connecting rod 14, and the extrusion ring 18 and the connecting block 19 are on the same horizontal line. Two sliding seats 21 are slidably connected inside the pipe body 11, and two rotating shafts 13 are respectively rotatably connected inside the two sliding seats 21. A sealing ring 22 is sleeved inside the pipe body 11. When the block 15 is clamped in the slot 12, the sleeve 17 is slid toward one end of the slot 12, and the sleeve 17 passes through the sliding process. The extrusion ring 18 squeezes the connecting block 19, so that the sliding seat 21 drives the connecting rod 14 to slide as a whole. At this time, the sleeve 17 and the connecting rod 14 surface fit together to limit it. During the sliding process of the connecting rod 14, the pipe body 11 is squeezed and extended into the sealing ring 22 to achieve the effect of sealing and fixed installation. When the pipe body 11 needs to be replaced and repaired, the sleeve 17 is slid toward one end of the slot 12. The sleeve 17 slides to release the limit on the connecting rod 14, and the sleeve 17 is driven to slide and reset through the force of the spring 16. The sliding seat 21 is pushed to the initial position by the sliding of the sleeve 17. During the operation, only the sliding sleeve 17 needs to be slid to complete the installation and disassembly of the pipe body 11. The operation is simple and convenient, which is conducive to improving the practicality of the device.

[0030] A mounting seat 23 is fixedly connected to the outer surface of the pipeline body 11, and a threaded rod 24 is slidably connected inside the mounting seat 23. A rotating block 25 is rotatably connected inside the mounting seat 23. The threaded rod 24 is threadedly connected to the inner surface of the rotating block 25. A clamping block 26 is slidably connected to the outer surface of the pipeline body 11. The clamping block 26 and the sleeve 17 are on the same horizontal line. The threaded rod 24 is rotatably connected inside the clamping block 26. After the pipeline body 11 is installed, the threaded rod 24 is screwed. During the rotation of the threaded rod 24, the clamping block 26 is pushed forward to slide. The clamping block 26 slides against the sleeve 17 to limit its position, thereby ensuring that the sleeve 17 is placed stably during daily use and preventing the sleeve 17 from loosening. When the sliding sleeve 17 is needed to install and disassemble the pipeline, the rotating block 25 is pulled outward, and the rotating block 25 rotates. At this time, the threaded rod 24 is pulled to loosen the limit on the sleeve 17, and the clamping block 26 slides against the sleeve 17 to limit its position, which is beneficial to improving the stability and safety of the device.

[0031] In view of the problems existing in the prior art, the utility model provides a natural gas pipeline connecting device. When the pipeline body 11 needs to be replaced and repaired, the sleeve 17 is slid toward one end of the slot 12. The sleeve 17 slides to loosen the limit on the connecting rod 14, and the sleeve 17 is driven to slide and reset through the action of the spring 16. The sliding seat 21 is pushed to the initial position by the sliding of the sleeve 17. During the operation, the installation and disassembly of the pipeline body 11 can be completed by sliding the sleeve 17. There is no need to use additional tools for disassembly. The operation is simple and convenient, which is conducive to improving the practicality of the device.

[0032] Working principle:

[0033] In the first step, multiple pipeline bodies 11 are connected to transport natural gas. When the pipeline bodies 11 are installed and connected, one section of the pipeline body 11 is inserted into another section of the pipeline body 11. When the pipeline body 11 is inserted, the clamping block 15 is squeezed to make the connecting rod 14 rotate around the rotating shaft 13 as the axis. The pipeline body 11 is fixed and limited by the clamping block 15 connected to the connecting rod 14 being clamped in the clamping groove 12. When the clamping block 15 is clamped in the clamping groove 12, the sleeve 17 is slid toward one end of the clamping groove 12. During the sliding process of the sleeve 17, the connecting block 19 is squeezed by the extrusion ring 18, so that the sliding seat 21 drives the connecting rod 14 to slide as a whole. At this time The sleeve 17 and the connecting rod 14 are fitted together to limit their surfaces. During the sliding process of the connecting rod 14, the pipe body 11 is squeezed and extended into the sealing ring 22 to achieve the effect of sealed fixed installation. When the pipe body 11 needs to be replaced and repaired, the sleeve 17 is slid toward one end of the slot 12. The sleeve 17 slides to release the limit on the connecting rod 14, and the sleeve 17 is driven to slide and reset through the force of the spring 16. The sliding seat 21 is pushed to the initial position by the sliding of the sleeve 17. During the operation, only the sliding sleeve 17 needs to be slid to complete the installation and disassembly of the pipe body 11. The operation is simple and convenient, which is conducive to improving the practicality of the device.

[0034] In the second step, after the installation of the pipeline body 11 is completed, the threaded rod 24 is screwed. During the rotation of the threaded rod 24, the clamping block 26 is pushed forward to slide. The clamping block 26 slides against the sleeve 17 to limit its position, ensuring that the sleeve 17 is placed stably during daily use and preventing the sleeve 17 from loosening. When it is necessary to slide the sleeve 17 for pipeline installation and disassembly, the rotating block 25 is pulled outward to rotate. At this time, the threaded rod 24 is pulled to loosen the limit on the sleeve 17, and the clamping block 26 slides against the sleeve 17 to limit its position, which is beneficial to improving the stability and safety of the device.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
