Abstract
A kind of more piece separated type hydraulic jack, including fore-set, hydraulic cylinder and check valve are the utility model is related to, the fore-set is three layers of cylinder, lower floor's body diameter is more than upper strata cylinder, lower two layers of cylindrical inside is hollow, and during contraction, upper strata cylinder can take in lower floor's cylindrical inside；The hydraulic cylinder inner hollow, in the scalable inlet hydraulic cylinder of fore-set, just there are two screws upside to hydraulic cylinder, hydraulic cylinder for it is front and rear cut vertically it is cylindric；The check valve is and adjacent with two-way valve in hydraulic cylinder side.The utility model is simple in construction, easy to use, cost is cheap, improves security using check valve, saves labour turnover, service life lengthens.
Description
Technical field
Mechanical field is the utility model is related to, particularly a kind of more piece separated type hydraulic jack.
Background technology
Automobile or and its when running into failure and being repaired, it is often necessary to be lifted, because jack is through commonly used work
Tool, existing hydraulic jack oil-returning structure are unable to the decrease speed of held stationary when zero load declines, but when dropping under loads, by
Increase in the internal pressure of oil cylinder chamber, the flow velocity of hydraulic medium increases, and declines institute's top load thing too fast, to operator and loaded article
Cause potential safety hazard.
Utility model content
The purpose of this utility model is solve above-mentioned existing defect, there is provided a kind of simple in construction, input cost is few, has
The more piece separated type hydraulic jack of high use value.
To solve above-mentioned technical problem, structure of the present utility model includes fore-set, hydraulic cylinder and check valve, the fore-set
For three layers of cylinder, lower floor's body diameter is more than upper strata cylinder, and lower two layers of cylindrical inside is hollow, and during contraction, upper strata cylinder can be received
Enter lower floor's cylindrical inside；The hydraulic cylinder inner hollow, in the scalable inlet hydraulic cylinder of fore-set, just there are two spiral shells upside to hydraulic cylinder
Hole, hydraulic cylinder are cut cylindric vertically for before and after；The check valve is and adjacent with two-way valve in hydraulic cylinder side.
Further, the fore-set is high-strength stainless steel.
Further, the fore-set lifting height is 44mm-97mm.
Further, the hydraulic cylinder bottom is the circular groove of indent.
Further, the hydraulic cylinder by the screw on surface by bolt by fore-set bottom inside hydraulic cylinder it is solid
It is fixed.
After said structure, the utility model has the advantages that：It is simple in construction, easy to use, cost is cheap, using unidirectional
Valve improves security, saves labour turnover, and service life lengthens.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality
New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is structural representation of the present utility model
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
As shown in figure 1, a kind of more piece separated type hydraulic jack is the utility model is related to, including including fore-set 1, hydraulic cylinder
2 and check valve 3, the fore-set 1 is three layers of cylinder, and lower floor's body diameter is more than upper strata cylinder, lower two layers of cylindrical inside be it is hollow,
During contraction, upper strata cylinder can take in lower floor's cylindrical inside；The inner hollow of hydraulic cylinder 2, in the scalable inlet hydraulic cylinder 2 of fore-set 1,
Just there are two screws 4 upside to hydraulic cylinder 2, and hydraulic cylinder 2 is cut cylindric vertically for before and after；The check valve 3 is in hydraulic cylinder 2
Side, and it is adjacent with two screws 4；The fore-set 1 is high-strength stainless steel；The lifting height of fore-set 1 is 44mm-97mm；
The bottom of hydraulic cylinder 2 is the circular groove of indent；The hydraulic cylinder 2 is existed the bottom of fore-set 1 by bolt by the screw 4 on surface
It is fixed inside the body of hydraulic cylinder 2.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, although ginseng
The utility model is described in detail according to previous embodiment, for those skilled in the art, it still can be with
Technical scheme described in foregoing embodiments is modified, or equivalent substitution is carried out to which part technical characteristic.It is all
Within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., this practicality should be included in
Within new protection domain.
