Existing hydraulic jack in use can produce gas in the cavity of cylinder body, if get rid of gas not in time, resistance when piston rod can be caused to move is in increase, and then poor stability when piston rod is run, the present invention by arranging outlet pipe on cylinder body, exhaust tube wall is arranged with stationary magazine creel by screwed tight, stationary magazine creel is hinged with end cap, stationary magazine creel is closed by end cap, coordinating of end cap and stationary magazine creel is realized by coordinating of elasticity clamp and draw-in groove, when elastic card plate is clamped in draw-in groove, elasticity clamp is had restoring force by compression and then realizes clamping, during use, stationary magazine creel is closed with end cap, and then realize closing of outlet pipe, make inner air pressure increasing when the gas of inner chamber of cylinder block increases, until end cap ejects by air pressure, the gas of inner chamber of cylinder block is discharged by outlet pipe, the present invention is by arranging outlet pipe, exhaust tube wall is arranged with stationary magazine creel by screwed tight, stationary magazine creel is hinged with end cap, end cap realizes clamping with coordinating of draw-in groove by elasticity clamp with stationary magazine creel, when inner chamber of cylinder block pressure is excessive, the elastic-restoring force of elasticity clamp can not make elastic card plate be clamped in draw-in groove, but end cap is ejected realization exhaust by chamber pressure, the problem of poor stability when the resistance avoiding inner chamber of cylinder block gas to cause causes piston rod to run, and, if elasticity clamp in use damages, can directly realize changing by changing stationary magazine creel.
Further, elasticity clamp comprises the fixed plate of trapezium structure, and the both sides of fixed plate are provided with groove, are provided with spring in groove, and the end of spring is provided with grip block, and the outer wall of grip block is parallel with the sidewall of fixed plate.
Specifically refer to that the cross section of fixed plate is trapezium structure.
Further, outlet pipe and cylinder body one-body molded.
Further, between cylinder head and piston rod, be provided with guide holder, in guide holder, be provided with fuel-displaced groove.
Along with the relative sliding of piston rod and guide holder, can discharge in time by the high-pressure oil gas compressed, thus reduce the speed fluctuation of piston rod, further improve the stability that hydraulic jack runs.
Further, filter screen is provided with in outlet pipe.
The setting of filter screen can avoid the impurity of outside when end cap is opened to enter into inner chamber of cylinder block.
Further, cylinder head, cylinder tail are fixedly connected with cylinder body respectively by bolt.
To sum up, the invention has the beneficial effects as follows:
The present invention is by arranging outlet pipe, exhaust tube wall is arranged with stationary magazine creel by screwed tight, stationary magazine creel is hinged with end cap, end cap realizes clamping with coordinating of draw-in groove by elasticity clamp with stationary magazine creel, when inner chamber of cylinder block pressure is excessive, the elastic-restoring force of elasticity clamp can not make elastic card plate be clamped in draw-in groove, but end cap is ejected realization exhaust by chamber pressure, the problem of poor stability when the resistance avoiding inner chamber of cylinder block gas to cause causes piston rod to run, and, if elasticity clamp in use damages, can directly realize changing by changing stationary magazine creel.
