[0002] A pressure gauge refers to a gauge using an elastic element as a sensitive element to measure and indicate pressure higher than ambient pressure, which is widely used and almost applied to all industrial processes and scientific research fields.

[0003] The existing pressure gauges are usually provided with a fixed pipe installed on the sidewall of a measured pipeline, and the fixed pipe is connected with the pressure gauge to test the water flow pressure in the pipeline. However, the equipment on the pipeline is sometimes knocked in construction, and the vibration is transmitted to the pressure gauge along the pipeline. The severe vibration can easily damage the parts of the pressure gauge, causing inaccurate reading. Moreover, the pressure gauge is usually screwed with the fixed pipe, and it is difficult to ensure that the side of the pressure gauge with reading faces the stable direction during the screwing process. Once the side of the pressure gauge with reading faces the ground, it is inconvenient for the staff to observe. SUMMARY

[0119] Operation process: when the pressure gauge 400 is needed to monitor the water pressure inside the pipeline 500, first, the pressure gauge 400 is connected with the second threaded pipe 303a, at this time, the third nut 303b is screwed, the third nut 303b can drive the second threaded pipe 303a to rotate, so that the pressure gauge 400 is connected with the second threaded pipe 303a, at this time, the connecting pipe 301 needs to be connected with the short pipe 202, the worker holds the connecting pipe 301 and inserts one end of the fixed rod 302 into the inside of the short pipe 202, inserts the connecting pipe 301 into the inside of the short pipe 202, the connecting pipe 301 drives the fixed rod 302 to insert into the first sliding groove 204a, continue to push the connecting pipe 301, so that the fixed rod 302 moves to the inside of the arc-shaped groove 204b, at the same time, the connecting pipe 301 drives the oil seal 305e to be located in the annular groove 305d, when the fixed rod 302 moves in the arc-shaped groove 204b, the oil seal 305e extrudes the sealing ring 305c, the sealing ring 305c drives the second spring 305b to shrink, the sealing ring 305c moves in the inside of the short pipe 202, at the same time, the fixed rod 302 drives the connecting pipe 301 to rotate, when the fixed rod 302 moves to the middle position of the arc-shaped groove 204b, continue to push the connecting pipe 301, the fixed rod 302 will drive the connecting pipe 301 to reverse, when the fixed rod 302 moves to the bottom of the arc-shaped groove 204b, the fixed rod 302 enters the inside of the L-shaped groove 204c, remove the force to push the connecting pipe 301, the second spring 305b restores to push the sealing ring 305c to move, the sealing ring 305c drives the oil seal 305e, the oil seal 305e drives the connecting pipe 301, the connecting pipe 301 drives the fixed rod 302 to move in the inside of the L-shaped groove 204c, so that the fixed rod 302 extrudes an insertion block 206e, so that the insertion block 206e enters the inside of the second limiting rod 205f, the insertion block 206e drives the long rod 206d to rotate on the shaft 206c, at the same time, the long rod 206d drives the return spring 206f to shrink, the long rod 206d drives another insertion block 206e to separate from the inside of the first insertion slot 206b and enter the inside of the second limiting rod 205f, at this time, the connecting pipe 301 is connected with the short pipe 202, at this time, the valve 203 is opened, the water flow in the pipeline 500 reaches the pressure gauge 400 through the hose 103a, the short pipe 202 and the connecting pipe 301, the water pressure in the pipeline 500 is monitored by the pressure gauge 400.

[0120] When it is necessary to disassemble the pressure gauge 400, the valve 203 is rotated to block the water flow in the short pipe 202, then the staff twists the rotating ring 304c, so that the rotating ring 304c drives the pull rope 304b, the pull rope 304b drives the moving plate 205d to move in the storage groove 205b, the moving plate 205d drives the first limiting rod 205e to be received in the first horizontal groove 205a, and the moving plate 205d drives the second limiting rod 205f to be received in the second horizontal groove 205c, at this time the fixed rod 302 loses the block of the second limiting rod 205f, and the fixed rod 302 can slide into the guide groove 204d, and finally is separated through the second sliding groove 204e, at this time the butt joint pipe 301 is separated from the short pipe 202.
