Abstract
The utility model relates to a hydraulic jack, which is in particular to suitable for supporting an automobile when overhauling under the automobile or replacing a tyre. A left cylinder and a right cylinder are arranged in the housing, a choking nozzle communicating the tops of the left cylinder and right cylinder is arranged in the housing, nozzle tips are arranged at the right upper side and left lower side of the housing, a piston barrel cooperating with the inner hole of the right cylinder and an auxiliary piston rod cooperating with the inner hole of the piston barrel are provided, an upper connecting plate is movably connected at the lower end of the auxiliary piston rod, a main piston rod cooperating with the inner hole of the left cylinder is provided, and one end of the main piston rod and the connecting plate is movably connected with a movable supporting. A monosomic multifunctional assembled valve is used for supplying and returning oil, which can save labor, be conveniently operated, and shorten the length of the oil cylinder.
Description
The utility model relates to a kind of hydraulic jack, especially is suitable for below the automobile supporting automobile in maintenance or the changing of tire.
At present, in maintenance or the changing of tire process, it is liftoff that common employing hand jack lifts an orientation or two orientation of car below automobile, handles not only difficultly but also inconvenient.
The purpose of this utility model provides a kind of automobile with oil cylinder jack in parallel, and it is to chew left cylinder in the connected sum control housing and right cylinder sequentially-operating on demand with current limliting, continuously makes kinematic support overhanging, and it is liftoff to lift automotive wheel.
The purpose of this utility model is achieved in that the housing that is provided with vertical cylindrical left cylinder and right cylinder, the choked flow that is communicated with left cylinder and right cylinder top is set in housing chews, being provided with the oil that is communicated with right cylinder top right side in the housing chews, be provided with piston cylinder with the mutual bearing fit of right cylinder endoporus, be provided with the piston rod of paying with the mutual bearing fit of piston cylinder endoporus, be provided with hinging manner bonded assembly connecting panel in the lower end of paying piston rod, be provided with the kinematic support that is connected the connecting panel lower end at the middle part with hinging manner, at the kinematic support left end, with hinging manner connect its lower end and with the main piston rod of the mutual bearing fit of left cylinder endoporus, the feet of at kinematic support right-hand member captive joint, and establish the oil that is communicated with left cylinder bottom portion left side in the housing and chew.
Owing to adopt such scheme, not only can realize not only laborsaving operation but also convenient, but also can adopt oil cylinder with motor-driven hydraulic ram system than weak point, make automobile lift to higher height, thereby the size of oil cylinder reduce greatly.
Below in conjunction with attached quarrel and embodiment the utility model is further specified.
Fig. 1 is embodiment of the utility model cylinder structure figure in parallel.
Fig. 2 is embodiment hydraulic scheme of the utility model.
Among Fig. 1: 1. housing, 2. choked flow is chewed, and 3. oil is chewed, 4. piston cylinder, 5. pair piston rod, 6. connecting panel, 7. kinematic support, 8. main piston rod, 9. feet, 10. oil is chewed, 11. spring frames, 12. right springs, 13. left springs.
Among Fig. 2: YB. hydraulic oil pump, Y. by pass valve, I. check valve, W. hand change over valve, S. two-way rotary valve.
In embodiment illustrated in figures 1 and 2, supply pressure oil by hydraulic oil pump YB, chew 3 for pressure oils through the by pass valve Y of the multi-functional combine valve of monomer pressure regulation, near the whole bush type hand change over valve of check valve I, interior outer gland sealing W is controlled at four wheels of automobile respectively two-way rotary valve S to oil cylinder housing 1 top oil, after bottom oil is chewed 10 oil returns to fuel tank, in this process, feet 9 is under the elongation of paying piston rod 5, piston cylinder 4, connecting panel 6, main piston rod 8 and kinematic support 7 promotes, each orientation wheel of jack-up automobile overhauls or wheel change.On the contrary, car test is repaiied or wheel change finishes, and need put down wheel, and with hand change over valve W commutation, two-way rotary valve S chews 10 oil-feeds to housing 1 bottom oil, and top oil is chewed 3 oil returns, and feet 9 restores to the original state.
Perpendicular put cylindrical right cylinder and left cylinder are set respectively in housing 1, be provided with the choked flow that is communicated with right cylinder and left cylinder top at housing 1 top and chew 2, this choked flow is chewed 2 and is played a control left side, right cylinder is the function of sequentially-operating on demand, oil is chewed 3 and is arranged on housing 1 top right cylinder right side, be communicated with right cylinder and two-way rotary valve S, be arranged on piston cylinder 4 with the mutual bearing fit of right cylinder endoporus, also has pair piston rod 5 at the mutual bearing fit of piston cylinder 4 endoporus, be connected an end of connecting panel 6 with hinging manner in the lower end of paying piston rod 5, and the other end of connecting panel 6 is connected the middle part of kinematic support 7 with hinging manner, and the left end of kinematic support 7 is connecting main piston rod 8 with the mutual bearing fit of left cylinder endoporus with hinging manner, the right-hand member captive joint of kinematic support 7 end of feet 9, the other end of feet 9 can direct contact ground, in housing 1 bottom, left cylinder left side, be provided with the oil that is communicated with left cylinder and two-way rotary valve S and chew 10, the bottom also is provided with and a left side in the left side housing 1, another choked flow that right cylinder is communicated with chews 2.Chew 3 oil-feeds from oil, oil is chewed in the 10 oil return processes, chew in choked flow under 2 the control, pressure oil at first promotes to pay a piston rod 5 and moves down, and kinematic support 7 is stretched, make and main piston rod 8 in-line again, this moment, feet 9 can be near to or in contact with ground, and along with the growth of oil pressure, the piston cylinder 4 in main piston rod 8 and the right cylinder continues overhanging together, with a certain wheel lift of automobile, and built on stilts.Spring frame 11, right spring 12 and left spring 13 are pushed the axis opposite side to by handle and are pinned kinematic support 7 simultaneously, have guaranteed that feet 9 is supported on ground-surface safety.When the maintenance or wheel change finish, from oil chew 10 oil-feeds, oil is chewed 3 oil returns, 2 effect is chewed in choked flow, at first main piston rod 8 withdrawal, driving a pair piston rod 5 also withdraws, feet 9 built on stilts, automotive wheels is landed, along with the growth of oil pressure, piston rod 4 is also withdrawn, borrow the effect of right spring 12, left spring 13 and spring frame 11, automatically terminate locking, with kinematic support 7 withdrawal original positions.
