Description

Technical Field

[0001] The utility model belongs to the technical field of safety auxiliary devices, and in particular relates to a safety auxiliary device for inspectors of buried pressure pipelines. Background Art

[0002] Buried pressure pipeline refers to a pipeline system buried underground for transporting fluids (such as oil, natural gas, etc.). These pipelines are subject to a certain internal pressure, so they are called pressure pipelines. When buried pressure pipelines are used for a long time, they need to be inspected and tested regularly, so safety auxiliary devices are needed. Safety auxiliary devices, also known as non-destructive testing instruments, are used to detect whether there is a gas leak in the pressure pipeline.

[0003] However, personnel in this field have found in actual use that most of the existing detectors are held by the user during use, and the detector is easy to slip from the user's hand and fall to the ground if not careful, thus causing damage and inconvenience to the user. In addition, most of the existing connecting tubes are directly sleeved on the connecting port, and such directly sleeved connecting tubes are easy to fall off, thus affecting the accuracy of the inspection and detection results. Utility Model Content

[0006] Preferably, the anti-fall mechanism includes a connecting rope, the connecting rope is fixedly connected to the outside of the fixing ring, the outside of the connecting rope is fixedly connected to a strap, one end of the strap is fixedly connected to a fixing shell, the other end of the strap is inserted into the fixing shell, a positioning hole is opened inside the strap, a fixing bolt is inserted into the inside of the fixing shell, the fixing bolt passes through the positioning hole and is threadedly connected to the inside of the fixing shell.

[0007] Preferably, the number of the locking holes is six, and the six locking holes are evenly distributed on the outside of the binding strap.

[0008] Preferably, one end of the strap is fixedly connected to a mother Velcro, and the other end of the strap is fixedly connected to a child Velcro, and the child Velcro is bonded to the mother Velcro.

[0009] Preferably, the locking mechanism includes four connecting blocks, and the four connecting blocks are fixedly connected to the outside of the non-destructive testing instrument body, and each two connecting blocks form a group. The inside of each group of connecting blocks is fixedly connected to a rotating shaft rod, and the outside of the rotating shaft rod is rotatably connected to a locking plate. Both sides of the connecting tube are fixedly connected to a clamping block, and the locking plate is clamped on the outside of the clamping block.

[0010] Preferably, the outside of the nondestructive testing instrument body is fixedly connected with two correspondingly distributed fixed blocks, the outsides of the two fixed blocks are fixedly connected with springs, and the two springs are respectively fixedly connected to the outside of the locking plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] By wrapping the strap around the arm, and then inserting the other end of the strap into the fixed shell, and then inserting the fixing bolt into the fixed shell and passing through the positioning hole, and then rotating the fixing bolt so that the fixing bolt is threadedly connected to the fixed shell, and then the sub-Velcro fixed to the inner side of the other end of the strap is adhered to the parent Velcro, thereby completing the secondary fixation. At this time, the strap can be firmly tied to the user's arm to prevent the device from falling to the ground and being damaged. Through this structural multi-porous adjustment method, it can be easily adapted to the use of arms of different thicknesses.

[0013] By rotating the two locking plates outward, the locking plates rotate around the rotating shaft rod, and then the connecting pipe is sleeved on the outside of the connecting port, and then the locking plates are released. At this time, the locking plates are pushed downward by the elasticity of the springs, so that the locking plates are pushed and connected to the outside of the card block, thereby effectively limiting the card block, making it difficult for the connecting pipe to fall off, and being more convenient for users to use.
