Summary:The utility model discloses a powerful mechanical self locking hydraulic cylinder of area buffering belongs to pneumatic cylinder technical field. When the pneumatic cylinder was in the unblock state, to the pressurization of no pole chamber, during piston rod to stroke end, the supporting shoe utilized the cooperation of compression spring, steel ball, latch segment and steel ball frame to realize the pneumatic cylinder auto -lock in getting into the steel ball frame, through realizing the pneumatic cylinder unblock to there being the pole chamber to pressurize, the cushion collar suit is in buffering on the nut, crosses oily clearance through the annular that forms between cushion collar and the cylinder cap internal diameter and is less than the annular that forms between cushion collar and the lock nut and crosses oily clearance and realize that the return stroke cushions. The utility model discloses a pneumatic cylinder locking is reliable and the unblock is simple and convenient, and buffer structure can slow down the terminal functioning speed of withdrawal, avoids the terminal impact of withdrawal, when the pneumatic cylinder started, hydraulic oil can pass through through the oily clearance of quick mistake, can not produce the slower phenomenon of toggle speed.
