Mechanical locking oil cylinder

ActiveCN224079394Uprevent backflowSimple design
The utility model belongs to the technical field of oil cylinders, and particularly relates to a mechanical locking oil cylinder which comprises a cylinder body, a locking cavity is formed in the cylinder body, a locking mechanism is installed in the locking cavity, the locking mechanism comprises a matching round block, a matching rod is fixedly installed on the matching round block, a steel ball is installed on the matching rod in a sliding mode, and the steel ball is arranged on the matching rod. When hydraulic oil is introduced into the oil inlet pipe, the steel ball is propped open so as to enter the left side of the sliding cavity to prop out the piston rod, and when hydraulic oil is stopped from being introduced from the oil inlet pipe, under the action of the spring, the piston rod is locked by the locking piston. The steel ball is pressed against the second L-shaped cavity, so that the function of locking the piston rod is achieved, after hydraulic oil is introduced from the oil return pipe, the hydraulic oil presses the locking piston out of the matching cavity, so that the steel ball is pressed away, so that locking of the piston rod is unlocked, the design structure is simple, and the automatic locking function is achieved.

Hand-held fence door structure for municipal park

ActiveCN119145758AChange the clamping forcehigh degree of automationGates/doorsBuilding braking devicesArchitectural engineeringMagnetic poles
The invention relates to the technical field of municipal equipment, and discloses a handheld fence door structure for a municipal park, which comprises a gravity type locking mechanism and a magnetic pole type pressure control mechanism. According to the hand-held fence door structure for the municipal park, the fence door frame can be opened by pulling the limiting pin rod upwards during opening, and when the hand-held fence door structure for the municipal park is closed, pressure change is generated on the buffer solution through repulsive force between the permanent magnets, so that the clamping force of the elastic gas film on the limiting pin rod is changed; and the limiting pin rod generates an automatic closing function under the action of self gravity, so that the automation degree of the device in the using process is improved, and the complexity of operation steps of the device is reduced.

Zero-point quick-change hydraulic base with linear jacking function

ActiveCN222176839Uavoid damageRealize automatic locking functionPositioning apparatusMetal-working holdersStructural engineeringControl theory
The utility model discloses a zero-point quick-change hydraulic base with a linear jacking function. The zero-point quick-change hydraulic base comprises a body, hydraulic zero point positioners are respectively arranged at four corners of the top surface of the body; at least three double-acting linear cylinders are arranged on the top surface of the body close to the middle area; the multiple double-acting linear cylinders are arranged at intervals, hydraulic rods are slidably connected to the tops of the multiple double-acting linear cylinders, the telescopic direction of the hydraulic rods is the vertical direction, and the multiple double-acting linear cylinders are connected with the same driving source. The bottom of the clamp is supported through the hydraulic rods extending upwards from the at least three double-acting linear cylinders, stable supporting of three points or more is achieved, the double-acting linear cylinders are driven through the same driving source, the hydraulic rods can stretch out and draw back synchronously, the clamp is kept parallel to the zero-point quick-change hydraulic base all the time in the dismounting and mounting process, and the dismounting and mounting efficiency is improved. And the zero-point quick-change unit is prevented from being damaged.
