Abstract
The utility model relates to the technical field of piston rod, concretely relates to a piston piece convenient to connect with piston rod, including piston, stem, be provided with positioning assembly between stem and piston, the inside of stem near piston one end is provided with cavity, the cavity of stem is provided with docking mechanism and locking mechanism, the positioning assembly includes soft magnetic block and magnet block, the soft magnetic block is fixed in docking plate end, the magnet block is fixed in connecting plate end, the soft magnetic block and magnet block magnetic suction cooperation, through setting up soft magnetic block and magnet block of piston end department mutual magnetic suction cooperation of end department of stem, realized the quick preposition of piston piece and piston rod. When magnetic suction is in place, utilize the inclined plane to push docking plate and finally make the clamping block embed in the clamping groove of piston under the action of limit spring, complete automatic mechanical locking, this structure utilizes magnetic attraction force to guide quick docking, guarantees the stability under the dynamic load of connection simultaneously, effectively prevents the loosening and falling.
