Abstract
The invention discloses a piston driving device in a manual hydraulic pump. The piston driving device comprises a pump shell, wherein the pump shell is movably provided with a propeller shell; after extending out of one end of the pump shell, the small diameter end of the propeller shell is fixedly connected with an operation hand wheel; the propeller shell is movably provided with a trunk piston; the outer periphery of the piston is provided with two spiral guide slots that are of mutual closed circulation; the propeller shell is provided with at least one propeller; and one end of the propeller extends into one guide slot. The specific structural type between the two spiral guide slots that are of mutual closed circulation and the propeller is as follows: when one propeller helically moves to the tail end of a spiral guide slot in the guide slot, the propeller can automatically slide to the other spiral guide slot and do spiral motion in reverse direction. The piston driving device is stable in operation process, small in needed operation space, and applicable to an electric liquid, gas liquid or hydraulic executing mechanism.
Description
Technical field
The present invention relates to the hydraulic hand-pump that uses in electrohydraulic control, refer more particularly to the piston driver in hydraulic hand-pump.
Background technique
Emergency power output under debugging and the state of emergency has obtained extensive various application to hydraulic hand-pump as hydraulic system, its principle is that operating grip drive piston moves reciprocatingly, order opening and closing by two one-way valves, complete the process of oil suction and the certain volume pressure oil of output, general hydraulic hand-pump is all to drive by linkage mechanism the structural type that piston pumps by handle, its advantage is simple in structure, and cost is low; Shortcoming is that the guidance quality of piston is bad, and piston easily weares and teares, impact sealing, and the shared space of operating grip to-and-fro motion is larger, can not be applicable to the compact occasion in operating space, and application area is restricted.
Summary of the invention
Technical problem to be solved by this invention is: thus piston driver in the less hydraulic hand-pump that can enlarge application area in a kind of action required space will be provided.
for solving the problems of the technologies described above, the technical solution used in the present invention is: the piston driver in described a kind of hydraulic hand-pump, comprise: pump case, be movably set with the propulsion device housing in pump case, the small-caliber end of propulsion device housing is fixedly connected with the operation handwheel after stretching out an end of pump case, be movably set with plunger piston in the propulsion device housing, one end of piston stretches out the other end of pump case, be provided with the spiral guide slot of two mutual closed loop cycle on the excircle of piston, at least one propulsion device is installed in the propulsion device housing, an angle of rake end stretches in the same guiding groove, article two, the spiral guide slot of mutual closed loop cycle and the specific constructive form between propulsion device are: when the tail end of this guiding groove was arrived in spiral motion in a certain spiral guide slot when a propulsion device, propulsion device can slide in another spiral guide slot automatically to oppositely for the helical movement on the contrary.
Be provided with two propulsion devices in described propulsion device housing in the above.
The invention has the beneficial effects as follows: utilize rotation motion and the efficient spiral rotating driving mechanism of handwheel, make piston realize to-and-fro motion, thereby complete oil suction and fuel-displaced process; Adopt the steering capability of structure back piston of the present invention better, move more steady, ring wear is also less, and steady, the required operating space of operating process is also less, has expanded the application area of hydraulic hand-pump.
