Description
Technical field
The utility model relates to a kind of secondary reinforcement Manual hydraulic jack.
Background technology
Manual hydraulic jack, as a kind of lifting heavy all-purpose tool used, is widely used in the every field such as machine up, building, railway, vehicle maintenance and repair, lifting transport.It is to be sealed in liquid in oil cylinder as medium, by hydraulic energy being converted to mechanical energy thus by weight upwards jack-up.
Conventional traditional manual hydraulic jack, its technical problem underlying existed is: idle travel and load stroke are same speed substantially, can not distinguish operating mode that is unloaded and load.And the time of heavy thing is lifted on the required top of the unloaded convergence of conventional hydraulic jacks, be usually greater than the top act time, work efficiency is low, and waste time and energy, field of application is narrow.Therefore, traditional manual hydraulic jack also exists speed and the opposed contradiction of strength.And adopt the Manual hydraulic jack of lever-toggle secondary reinforcement mechanism, although it is large to have unloaded hourly velocity, the advantage of High power output during load, comprises piston rod altogether containing 5 moving members, and cause jack complicated integral structure, manufacturing process is loaded down with trivial details.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides the secondary reinforcement Manual hydraulic jack that a kind of structure is simple, have better reinforcement effect.
The utility model solves the technical scheme that its technical matters adopts: a kind of secondary reinforcement Manual hydraulic jack, comprise jacking portion and drive division, described jacking portion comprises cylinder body, with the piston of inboard wall of cylinder block bearing fit, treat that the weight of jacking is placed in piston upper surface, described drive division comprises the pump housing, with the plunger of pump housing inwall bearing fit, promote plunger reciprocating lever handle and fuel tank in the pump housing, the pedestal part of lever handle lower end and the pump housing is hinged, the pump housing have oil pocket pipeline to connect fuel tank and cylinder body have oil pocket, toggle link is provided with between described lever handle and plunger, toggle link one end and lever handle hinged, the toggle link other end and plunger outer end hinged.
For the turnover of hydraulic control oil, the pipeline between the described pump housing and fuel tank is provided with in line check valve, and the pipeline between the pump housing and cylinder body is provided with oil outlet one-way valve.
In order to control, hydraulic oil in cylinder body is stable returns fuel tank, and the described pump housing leads between the pipeline of cylinder body and fuel tank and is provided with oil cock.
The beneficial effects of the utility model are: the utility model solves the speed and the opposed contradiction of strength that exist in conventional hydraulic jacks, can accomplish that unloaded hourly velocity is large, High power output during load, compared with traditional manual hydraulic jack, work efficiency significantly improves; Simultaneously compared with adopting the secondary reinforcement Manual hydraulic jack of lever-toggle structure, drive part pedestal plug only has three moving members, designs simplification, and can play better reinforcement effect.

Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of secondary reinforcement Manual hydraulic jack as shown in Figure 1, comprise jacking portion and drive division, described jacking portion comprises cylinder body 1 and piston 2, and piston 2 is with cylinder body 1 inwall bearing fit and move up and down in drive division effect, treats that the weight 3 of jacking is placed in piston 2 upper surface.
Described drive division comprises the pump housing 4, plunger 5, promote plunger 5 reciprocating lever handle 6 and fuel tank 7 in the pump housing 4, plunger 5 and the pump housing 4 inwall bearing fit, the pedestal part of lever handle 6 lower end and the pump housing 4 is hinged, the pump housing 4 have oil pocket pipeline to connect fuel tank 7 and cylinder body 1 have oil pocket, pipeline between the pump housing 4 and fuel tank 7 is provided with in line check valve 9, pipeline between the pump housing 4 and cylinder body 1 is provided with oil outlet one-way valve 10, with the turnover of hydraulic control oil, and lead between the pipeline of cylinder body 1 and fuel tank 7 at the pump housing 4 and be also provided with oil cock 11, by regulating oil cock 11 angle, so that hydraulic oil can stably return in fuel tank 7 when piston 2 return.
Toggle link 8 is provided with between described lever handle 6 and plunger 5, toggle link 8 one end and lever handle 6 hinged, toggle link 8 other end and plunger 5 outer end hinged, lever handle 6 and toggle link 8 constitute the force-increasing mechanism that drive division promotes piston 2 lifting, by lever handle 6 upwards, downward repeatedly lift pressure, plunger 5 is reciprocating in the pump housing 4, is constantly elevated and lifting weight 3 by pipeline driven plunger 2.
During operation, when pressing lever handle 6 downwards, hinged toggle link 8 thereon drives plunger 5 to move right, when the pump housing 4 has the sealed volume of oil pocket to increase formation parital vacuum, in line check valve 9 is opened, hydraulic oil in fuel tank 7 enters the pump housing 4 by pipeline under the effect of bar pressure to be had in oil pocket, completes an oil suction action; When firmly upwards lifting lever handle 6, hinged toggle link 8 thereon promotes plunger 5 and is moved to the left, the pump housing 4 is made to have the sealed volume of oil pocket to reduce, oil pressure raises, in line check valve 9 is closed, and oil outlet one-way valve 10 is opened, and what hydraulic oil entered cylinder body 1 has in oil pocket, driven plunger 2 makes weight 3 rise a segment distance, completes a force feed action.
Complete the moment of force feed action, continue upwards to lift lever handle 6, toggle link 8 drives plunger 5 to move right, and completes again an oil suction action, when firmly promoting lever handle 6 downwards, toggle link 8 promotes plunger 5 and is moved to the left, complete again a force feed action, circulation like this is lifted repeatedly, press lever handle 6, hydraulic oil just can be made constantly to be pressed in cylinder body 1, weight 3 is constantly raised, thus reaches the object of lifting; As drained the oil, by oil cock 11 half-twist, piston 2 deadweight and external force effect under realize backhaul.
The structure that the utility model adopts lever-toggle link to combine, solve the speed and the opposed contradiction of strength that exist in conventional hydraulic jacks, can accomplish that unloaded hourly velocity is large, High power output during load, compared with traditional manual hydraulic jack, work efficiency significantly improves; Simultaneously compared with adopting the secondary reinforcement Manual hydraulic jack of lever-toggle structure, drive part pedestal plug 5 also only has three moving members interior, and jack integral structure is simplified, and can play better reinforcement effect.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
