Abstract
A quick connector is described to removably connect hydraulic equipment operating in underground coal mines, wherein two tubular bodies are coupled to each other such as to define one individual fluid passage, a tubular element is movable between a closed position and an open position in which it either blocks or allows a relative axial movement between the tubular bodies, respectively, and a safety member slides on the tubular element between at least one safety position and a freedom position, wherein it either blocks or allows the tubular element to move to the open position, respectively.
Claims20
A connector, comprising:
- a first tubular body defining a fluid passage;
- a second tubular body defining a fluid passage and being axially removably coupled to said first body in a fluid-tight manner such as to define one individual fluid passage;
- a removable locking device arranged to lock a relative axial movement between said first body and said second body;
- a tubular element axially movable relative to said first body and said second body with the possibility of adopting a closed position, in which it fastens said locking device to lock said relative axial movement and an open position, in which it releases said locking device to enable said relative axial movement;
- and
- at least one safety member movable relative to said tubular element between at least one safety position, in which it is proximate to at least one abutment arranged on said first body to prevent said tubular element to move to said open position, and a freedom position, in which it is away from said at least one abutment to allow said tubular element to move to said open position, said at least one safety member comprising a tubular body coupled to said tubular element by means of a screw coupling.

- and
- a first sealing element arranged between said at least one safety member and said tubular element to prevent dirt from entering from outside a coupling area in which said at least one safety member is coupled to said tubular element.
