With the contact of circular groove and tube wall, gas leak is prevented.Small sealing ring is first of gas leak defence line, and large sealing packing ring is
Two gas leak defence lines.Sealing shroud hardness is larger, be "convex" shaped, effect mainly support connecting elements, prevent its to
Lower deflection, to cannot be hooked on connecting hole；Another effect is when connecting elements fails normally to be hooked on one with connecting hole
When rising, sealing shroud prevents from being connected to connecting tube disconnection by the frictional force with tube wall, while also functioning to certain sealing function.
It is connected with spring between tool upper end and tool lower end, can be made lower flexible thereon.The work of upper thimble and lower thimble
When with the connecting tube being mainly connected in fractionation, by inwardly squeezing the connecting elements of latter connecting tube, make it can not hook
It is then slightly firmly outer to pull out latter connecting tube on the connecting hole for hanging over previous connecting tube, latter connecting tube can be torn open
It separates.
There is length scale with the intubation end pipe of the connecting tube of the utility model, it can convenient reading sampling point position.
The utility model has reached following beneficial effect：
The sampling pipe of the utility model includes end pipe, multiple connecting tubes, auxiliary unlocking tool, can be adjusted as needed whole
The length of a sampling pipe；Between connecting tube can quickly grafting sealing it is self-locking, it is easy to connect quickly；Size quarter is indicated outside connecting tube
Degree, convenient for reading the depth deeply to drill；Sealing ring, sealing shroud can guarantee the leakproofness between connecting tube；Assist unlocking tool
Two connected connecting tube quick releases can be split, it is easy to operate, it is time saving and energy saving.
