The invention relates to a safe self-locking oil cylinder capable of being flexibly adjusted. The oil cylinder comprises a cylinder body, wherein a rear end cover is mounted at the rear end of the cylinder body; a piston is arranged in the cylinder body; a piston rod is mounted on the piston; the piston rod comprises a supporting rod and a push rod; the supporting rod and the push rod are matchedthrough a self-locking component. The oil cylinder can reduce the friction among a cylinder barrel wall, the piston and the self-locking component, thereby solving the problems that the degree of precision of inner wall of the oil cylinder is attrited, and the service life is shortened; the device is simple to mount, can flexibly adjust the locking position, is simple in production technology, lowin cost and convenient for part replacement.
Description
technical field [0001] The invention relates to the technical field of oil cylinders, in particular to a flexibly adjustable safety self-locking oil cylinder. Background technique [0002] In the mechanical oil cylinder used in the existing fluid medium braking technology, when the force of the liquid medium changes unexpectedly or cannot resist the change of the gravity of the object lifted by the oil cylinder, unexpected danger occurs. When the existing oil cylinder lifts the extra-heavy object to the designated high position, when the press, the oil delivery pipe fails or other assembly parts have oil leakage problems, the bearing force of the fluid medium in the oil cylinder will change at this time, and the lifted The extremely heavy object that was lifted will fall under its own gravity due to failure, resulting in danger. [0003] In the industry of existing mold injection molding products, when the mold is inconvenient to be used as a reaction force mechanism, and t...
