Undercarriage receive and releases two-way jack catch keying of pressurized strut to be constructed

The utility model provides an undercarriage receive and releases two-way jack catch keying of pressurized strut to be constructed, includes the urceolus that both ends were established by upper end cover and lower extreme cap seal, is equipped with mouthpiece and urceolus inner chamber on this upper end cover and communicates with each other, and the intracavity is equipped with the action piston of taking the piston rod in this urceolus, and this bottom end cover is stretched out to the one end of this piston rod, and should move the inner chamber cavity of piston and piston rod, should move to set up uplock control mechanism in the inner chamber of piston and piston rod, and the urceolus inner chamber that is arranged in outside this piston rod sets up down lock control mechanism. The utility model discloses with the uplock, receive and release and bear the weight of function collection in an organic whole, the space has been saved to the sexual valence relative altitude, has lightened mechanism's weight. The utility model discloses it is limited that the pressurized strut can be used to the space, and weight requires harshlyer, bears in the load lock pressurized strut mechanism of great ground.
