Valve is respectively used to the break-make of control female connector and pin end, and the female connector is equipped with annular groove, is set in the annular groove
There is steel ball, the periphery upper ring cap of the female connector to there is lock housing, the pin end to be used cooperatively with female connector, the pin end and
Hydraulic oil pipe is connected separately on female connector.Belong to the prior art in such a way that steel ball is come fixed hydraulic quick coupling, at this
It does not do in scheme and excessively repeats.
Further, the periphery of the female connector detects the break-make of the first ball valve equipped with first close to switch, described
The periphery of pin end detects the break-make of the second ball valve equipped with second close to switch.
Further, first ball valve includes the first in command, and the second ball valve includes second handle, the described first close switch
Judge the break-make of the first ball valve by detecting the position of the first in command, second passes through the position of detection second handle close to switch
To detect the break-make of the second ball valve.The position that the mobile objects such as handle how are detected close to switch belongs to the prior art, here
It repeats no more.
Further, the female connector is equipped with warning device, and the female connector is equipped with third close to switch, the third
Position close to switch for detecting lock housing.
Further, lock housing spring is equipped between the lock housing and female connector.
Further, the warning device approaches switch, the second close switch and third close to switching signal with first respectively
Connection.
Compared with prior art, the utility model has the beneficial effects that：
The pin end of this programme is still fixedly connected with mode, this side using steel ball with female connector with what lock housing was used cooperatively
Formula can make connection more stablize；
Replace the position of check valve in original quick coupling using the first ball valve and the second ball valve, the through-hole on ball valve with
Pin end is compared with the diameter of female connector, and variation is smaller；Existing quick coupling is solved because of pressure caused by application check valve
Lose larger and complicated problem.
