The novel beneficial effect has long service life, can not generate the locking phenomenon of the core shaft and the shell, and is safe to use.
Description
Technical Field
The utility model relates to a tap field is used in the probing, in particular to tap is used in probing.
Background
The existing water faucet for drilling adopts 2 or more O-shaped structure rubber sealing rings, the fit clearance between a middle mandrel and a shell is 0.05-0.1mm, the phenomenon of locking of the mandrel and the shell is easy to occur during drilling operation, a water inlet hose can be caused to rotate greatly along with a drill rod, and the harm threat to operators of a machine table can be caused; the O-shaped rubber ring is not wear-resistant and has short service life, and a faucet adopting the lip-shaped rubber sealing ring is also not wear-resistant, has low pressure resistance and has short service life.
Therefore, it is necessary to design a faucet for drilling, which has a long service life, does not cause locking of the core shaft and the shell, and is safe to use.
