Abstract
The utility model relates to a multifunctional hydraulic jack belonging to the tool class, which is composed of a piston rod, a support tool, a clamping plate, the support tool of an oil cylinder, an oil cylinder, etc. The utility model is characterized in that the oil cylinder is screwed with the clamping plate of the oil cylinder, the clamping plate of the oil cylinder is screwed with the support tool of the oil cylinder, the end head of a piston rod is provided with a jack head, the piston rod is screwed with the clamping plate, the clamping plate is screwed with the support tooland a sealing ring is arranged between the upper end of the clamping plate of the oil cylinder and the oil cylinder. The utility model has simple structure and reasonable design. The utility model can not only play the supporting function but also can play the stretching and extruding function when various corresponding auxiliary tools are replaced.
Description
The utility model relates to a kind of multifunction hydraulic jack, belongs to the instrument class.
At present, make the hydraulic jack instrument do the local a lot of of back work in the society, it mainly is the ability that has Yi Dingding very heavy, can play the effect of jacking weight, as: when automotive servicing changes tire, must be with hydraulic jack jacking axletree, so that can dismantle smoothly and changing of tire.In general production and maintenance except that the jacking back work of need necessity, stretch, it also is to keep away unavoidable back work in general production and the maintenance that extruding is cut off, yet, existing hydraulic jack function singleness, range of use is limited, can only rise unidirectional location, powerless for stretching and extruding required in producing and keeping in repair, can not fully play and utilize the work efficiency of its jack, when in producing and keeping in repair, running into the back work of essential stretching or extruding cut-out, also need look for auxiliary assembly tool to help to stretch in addition or the extruding cut-out, just can finish the task of its production or maintenance, existing in a word hydraulic jack instrument can not satisfy the needs in people's production and the maintenance fully.
The purpose of this utility model is that the jack that designs a kind of later-model band holder tool and chuck can play a kind of multifunction hydraulic jack that the jacking effect can be played stretching, extruding cutting action again under the multiple corresponding instrument situation of replacing.
The purpose of this utility model is to realize like this, it mainly is made up of piston rod (1), chuck (2), holder tool (3), oil cylinder chuck (4), oil cylinder parts such as (5), it is characterized in that: screwed oil cylinder holder tool (6) on the oil cylinder (5), screwed oil cylinder chuck (4) on the oil cylinder holder tool (6), the termination of piston rod (1) is provided with jack head (7), screwed holder tool (3) on the following piston rod (1) of jack head (7), screw chuck (2) on the holder tool (3), be provided with seal ring (8) between the upper end of oil cylinder holder tool (6) and the oil cylinder (5).
The utility model is compared with prior art: it is simple in structure, reasonable in design, under the prerequisite that does not change original hydraulic jack roof construction, it is transformed, make it when supplement production and maintenance, can play the jacking effect and can play the effect of stretching, extruding again, be a kind of desirable multifunction hydraulic jack easy to use.
Further specify below in conjunction with drawings and Examples:
Accompanying drawing 1 is a schematic appearance of the present utility model.
Accompanying drawing 2 is the sectional structure scheme drawing after transformation part in the place's of drawing a circle is suitably amplified among Fig. 1.
Accompanying drawing 3 is the semi-sictional view constructional drawing of the utility model parts chuck (2).
Accompanying drawing 4 is the birds-eye view of the utility model parts chuck (2).
Accompanying drawing 5 is the semi-sictional view constructional drawing of the utility model parts holder tool (3).
Accompanying drawing 6 is the birds-eye view of the utility model parts holder tool (3).
Accompanying drawing 7 is the semi-sictional view constructional drawing of the utility model parts oil cylinder holder tool (6).
Accompanying drawing 8 is the birds-eye view of the utility model parts oil cylinder holder tool (6).
Among the figure: 1, piston rod, 2, chuck, 3, the holder tool, 4, the oil cylinder chuck, 5, oil cylinder, 6, oil cylinder holder tool, 7, jack head, 8, seal ring, 9, the oil storage storehouse.
As can be seen from the figure, it mainly is to utilize existing jack transformation to form for the utility model, it is by piston rod (1), chuck (2), holder tool (3), oil cylinder chuck (4), part such as oil cylinder (5) is formed, it transforms part: screwed oil cylinder holder tool (6) on the oil cylinder (5), screwed oil cylinder chuck (4) on the oil cylinder holder tool (6), the termination of piston rod (1) is provided with jack head (7), screwed holder tool (3) on the following piston rod (1) of jack head (7), screw chuck (2) on the holder tool (3), be provided with seal ring (8) between the upper end of oil cylinder holder tool (6) and the oil cylinder (5).Oil storage storehouse (9) are prior art among the figure, repeat no more here.The parts that utilization increases newly, promptly chuck (2), holder tool (3) and oil cylinder chuck (4), oil cylinder holder tool (6) just can be changed the cooperation corresponding tool very easily the needs extruding and the object that cuts off that stretches are processed, produced or keep in repair.Unidirectional location is risen make the low level lifting into.That is to say when needing extruding and the corresponding instrument that will use when cutting off of stretching sandwiches in the screw socket of setting tool of chuck (2), holder tool (3) and oil cylinder chuck (4), oil cylinder holder tool (6) composition and tightens, can finish multiple work, utilize the contractility of this multifunction hydraulic jack can reach multiple purpose.Its function is still constant when the needs jacking.
