[0001] The utility model relates to the technical field of gas meter installation, and more particularly to a convenient connection device for a gas meter and a gas pipeline. Background Art
[0002] Gas meters and gas pipelines are essential components of a household gas supply system. Gas pipelines transport gas from the source to the user's home, while gas meters measure the amount of gas used. Currently, a connector is typically used to connect the gas meter and gas pipeline. This requires first connecting one end of the connector to the gas meter and then the other end to the gas pipeline. This process is cumbersome and prevents simultaneous installation of both ends of the connector on the gas meter and pipeline, leaving room for improvement. Utility Model Content

The convenient connection device between a gas meter and a gas pipeline involved in the present invention is not limited to the various structures recorded in the following embodiments. All other implementation methods obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0019] Example 1:
[0020] like Figure 1-4 As shown, a convenient connection device for a gas meter and a gas pipeline comprises a connecting pipe 1, the top and bottom ends of the outer wall of the connecting pipe 1 are provided with external threads, the bottom end of the outer wall of the connecting pipe 1 is provided with a lower threaded connector 5, the top end of the outer wall of the connecting pipe 1 is provided with an upper threaded connector 6, the inner walls of the lower threaded connector 5 and the upper threaded connector 6 are provided with internal threads, the inner wall thread of the lower threaded connector 5 is sleeved on the bottom end of the outer wall of the connecting pipe 1, the inner thread of the upper threaded connector 6 is sleeved on the top end of the outer wall of the connecting pipe 1, the middle part of the outer wall of the connecting pipe 1 is fixedly sleeved with a fixed cover 2, the outer wall of the fixed cover 2 is movably sleeved with a rotating cover 3, the inner wall of the fixed cover 2 is provided with a plurality of annular grooves 21, and the inner wall of the rotating cover 3 is fixedly connected with a plurality of limiting grooves. A plurality of limit sliders 4 are provided at the top of the outer wall of the rotating cover 3, and the outer walls of the plurality of limit sliders 4 are all slidably connected to the inner wall of the annular slide 21. A plurality of No. 1 limit slides 53 are provided at the bottom of the outer wall of the rotating cover 3, and the upper parts of the plurality of No. 1 limit slides 53 are all slidably connected to the No. 1 limit block 52. A plurality of No. 1 connecting rods 51 are fixedly connected to the upper part of the outer wall of the lower threaded connector 5, and the top end of the No. 1 connecting rod 51 is fixedly connected to one side of the No. 1 limit block 52. A plurality of No. 2 limit slides 63 are provided at the top of the outer wall of the rotating cover 3, and the lower parts of the plurality of No. 2 limit slides 63 are all slidably connected to the No. 2 limit block 62. A plurality of No. 2 connecting rods 61 are fixedly connected to the lower part of the outer wall of the upper threaded connector 6, and the bottom end of the No. 2 connecting rod 61 is fixedly connected to one side of the No. 2 limit block 62.
[0021] When the cam 21 is in the closed position, the cam 21 is in the closed position, and the cam 22 is in the closed position, so that the cam 22 is in the closed position and the cam 22 is in the closed position.
[0022] Example 2:
[0023] like Figure 1-4 As shown, annular sealing grooves 7 are provided at the upper and lower ends of the lower threaded connector 5 and the upper threaded connector 6 .
[0024] In this embodiment, when the lower threaded connector 5 and the upper threaded connector 6 are respectively screwed on the joints between the gas meter and the gas pipeline, the staff can use sealant to apply inside the annular sealing grooves 7 at both ends of the lower threaded connector 5 and the upper threaded connector 6, so as to facilitate sealing the connection between the two ends of the connection device and the gas meter and the gas pipeline.
[0025] In summary, if Figure 1-4 As shown, this is a convenient connection device for a gas meter and a gas pipeline. When in use, the staff first moves the two ends of the connecting pipe 1 to the gas meter joint and the gas pipeline joint respectively, and then rotates the rotating cover 3. The rotating cover 3 drives multiple limit sliders 4 to slide inside the annular slide groove 21. The rotating cover 3 drives the lower threaded connector 5 to move spirally at the bottom end of the outer wall of the connecting pipe 1 through the No. 1 limit block 52 and the No. 1 connecting rod 51. When the lower threaded connector 5 moves spirally, it can drive the No. 1 limit block 52 in the No. 1 limit slide groove 53 through the No. 1 connecting rod 51. The inner part slides downward, and at this time the lower inner wall of the lower threaded connector 5 can be screwed onto the gas meter joint. While the rotating cover 3 rotates, it drives the upper threaded connector 6 to be screwed onto the gas pipeline joint in the same way through the No. 2 limit block 62 and the No. 2 connecting rod 61, making it easy to install both ends of the connecting pipe 1 on the gas meter and the gas pipeline simultaneously. The staff then uses sealant to apply inside the annular sealing grooves 7 at both ends of the lower threaded connector 5 and the upper threaded connector 6, thereby facilitating the sealing of the connection device with the gas meter and the gas pipeline.
