DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

The gas pipeline, the fixing plate 3 and the locking bolt 4 cooperate to lock the natural gas pipeline. When the mounting holes of the two natural gas pipeline flanges are connected, the construction personnel can rotate the inner bracket 2 to make the inner bracket 2 and the locking bolt 4 drive the natural gas pipeline to rotate, so that the mounting holes of the flange of the natural gas pipeline can be rotated, which is convenient for the mounting holes of the flanges of the two natural gas pipelines to correspond, and plays the role of an assistant. It has the effects of simple and convenient operation, fast adjustment and docking speed; and by using the base 12 to contact the ground, the rotating disk 10 is rotatably and slidingly connected with the slider 13 on the top of the base 12 through the annular slide groove 11, which can support the telescopic rod 9 and the outer bracket 1 on its top, and the natural gas pipeline locked inside the outer bracket 1 can be adjusted in angle by rotating the outer bracket 1, thereby improving the flexibility of the device.

[0026] Furthermore, the top of the telescopic rod 9 is fixedly connected to the bottom of the outer bracket 1, and the bottom end of the telescopic rod 9 is located at the center of the top of the rotating disk 10. Through the setting of the telescopic rod 9, it supports the outer bracket 1 and connects the outer bracket 1 and the rotating disk 10.

[0027] Furthermore, two guide grooves 14 are provided inside the rotating disk 10 , and limiting bolts 15 fixedly connected to the base 12 are slidably connected inside the guide grooves 14 . The setting of the guide grooves 14 facilitates the rotation of the rotating disk 10 .

[0028] Furthermore, the surface of the limiting bolt 15 is threadedly connected to the limiting nut 16, and the bottom of the limiting nut 16 contacts the top of the rotating disk 10. The limiting nut 16 is configured to lock the limiting bolt 15. By contacting the bottom of the limiting nut 16 with the top of the rotating disk 10, the rotating disk 10 can be locked to prevent the rotating disk 10 from rotating.

[0029] Furthermore, two connecting rods 17 are fixedly connected to the top of the limiting nut 16 , and the two connecting rods 17 are symmetrically arranged. Through the arrangement of the connecting rods 17 , it is convenient for the user to rotate the limiting nut 16 .

[0030] Furthermore, an anti-skid pad 18 is fixedly connected to the bottom of the fixed block 5, and the bottom of the anti-skid pad 18 is in contact with the natural gas pipeline.

[0031] Brief description of the use process: When in use, the natural gas pipeline is passed between the fixing plate 3 and the inner bracket 2 and placed on the top of the inner bracket 2. By rotating the locking bolt 4, the anti-skid pad 18 at the bottom end of the locking bolt 4 is in contact with the natural gas pipeline, and the locking bolt 4 is locked. At this time, the natural gas pipeline is limited;

[0032] When the mounting holes of the flanges of the two natural gas pipelines do not correspond, the inner bracket 2 is rotated to drive the natural gas pipeline on the top of the inner bracket 2 to rotate. When the natural gas pipeline rotates, the flange connected to it and the mounting holes inside the flange will also rotate. By rotating to make the mounting holes of the natural gas flange and the mounting holes of the natural gas flange to be connected, the two natural gas pipelines can be connected by passing screws through the two mounting holes.

[0033] Before installation, the natural gas pipeline needs to be adjusted in angle. The limit nut 16 and the rotating disk 10 are separated by rotation, and then the outer bracket 1 is rotated. The rotation of the outer bracket 1 will drive the telescopic rod 9 and the rotating disk 10 to rotate. At this time, the natural gas pipeline fixed on the top of the inner bracket 2 will also rotate and change its angle. After reaching a suitable angle, the two limit nuts 16 are locked so that the bottom of the limit nuts 16 and the top of the rotating disk 10 are in contact. The rotating disk 10, the telescopic rod 9, the outer bracket 1, the inner bracket 2 and the natural gas pipeline locked by the inner bracket 2 and the locking bolt 4 can be limited.
