Specific embodiment
It is with reference to the accompanying drawing and specific real in order to be more clearly understood that the above objects, features and advantages of the present invention
Applying mode, the present invention is further described in detail.It should be noted that in the absence of conflict, the implementation of the application
Feature in example and embodiment can be combined with each other.
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention, still, the present invention may be used also
To be implemented using other than the one described here other modes, therefore, protection scope of the present invention is not by described below
Specific embodiment limitation.
According to some embodiments of the present invention referring to Fig. 1 description.
As shown in Figure 1, the jack 1 using aqueous medium of the one embodiment proposed according to the present invention, comprising: mutual spiral shell
The cylinder barrel 10 and cylinder bottom 12 of line connection, wherein axial one end of cylinder barrel 10 is arranged in cylinder bottom 12, and cylinder bottom 12 and cylinder barrel 10 surround out
One cavity, the inner surface of cavity are equipped with erosion resistant coating, and cavity is for accommodating water, using as hydraulic medium.
In this embodiment, due to using water as hydraulic medium, it is possible to which generating to corrode to cylinder barrel 10, cylinder bottom 12 causes
It gets rusty, influences the use of jack 1, it is therefore desirable to which erosion resistant coating, the structure of this tubbiness are all set at the position of all contact water
Inconvenience carries out preservative treatment, therefore cylinder barrel 10 in the application and cylinder bottom 12 are split type structure, after progress preservative treatment again
It connects together, in this way by the way that cylinder bottom 12 to be set as being threadedly coupled with cylinder barrel 10, in connection procedure, due to there is no the poles such as high temperature
Situation is held, so that the erosion resistant coating of cavity inner surface will not be destroyed, it is ensured that anti-corrosion effect extends the service life of jack 1；
Further, it using threaded connection, is also convenient for disassembling and maintaining, even if erosion resistant coating falls off, cylinder bottom 12 can also be removed, again
Arrange erosion resistant coating；Further, for other be detachably connected, such as the modes such as riveting, clamping, threaded connection
Mode better tightness, and force way is face stress, the mode of the point stress such as relatively riveting, clamping does not have in structure more uniformly
There are weak part or the excessive position of stress, the stability to work under this larger pressure of jack 1 is more preferable, disassembly process
The deformation that will not lead to cylinder bottom 12 or cylinder barrel 10 is conducive to reuse.
It is to be appreciated that the water in the application include pure water, it is mineral water, natural water, any one in natural mineral water
Kind.
In the above-described embodiments, jack 1 is carried bottom jack, for general jack 1, in carried bottom jack
It is middle to use water as hydraulic medium, it is more advantageous to the replacement at any time and supplement of hydraulic medium, there is carried bottom jack more extensively
Use scope.
In the above-described embodiments, erosion resistant coating can be any one in electroplated layer, anticorrosive paint, chemical deposit, or
Any several engagement, for example, by using electro-coppering, electroless copper, electrogalvanizing etc., in this way convenient for according to specifically used environment, use
Different erosion resistant coatings, the service life of lifting jack 1 or the convenience in maintenance.

Side, cylinder bottom 12 easy to disassemble in this way promotes the convenience that uses of maintenance.
In the above-described embodiments, installation clamping part 14 includes at least one blind hole, in tool easy to disassemble insertion blind hole and
Cylinder bottom 12 is driven to rotate, thus realize dismounting, it, can be to avoid the leakage of the water in jack 1 using blind hole.
It is to be appreciated that blind hole can be with only one, when only one blind hole, the shape of blind hole is polygon, center
Line is overlapped with the center line of cylinder barrel 10, is rotated so that the extracting tool being adapted to the blind hole is able to drive cylinder bottom 12；The number of blind hole
Amount is also possible to multiple, is more convenient for exerting a force in this way, reduces the labor intensity of dismounting.
It may also be noted that space can also be saved using the structure type of blind hole using installation clamping part 14, reduce
Materials'use amount.
In some embodiments, installation clamping part 14 includes multiple protrusions to outside cylinder barrel 10, is conducive to user in this way and exists
In the case where there is no dismantling device, directly holds protrusion and dismounted, promote the convenience of dismounting.
In any of the above-described embodiment, the jack 1 using aqueous medium further includes having sealing element, although using screw thread
The structure type of connection, it can be difficult to avoiding the gap between cylinder barrel 10 and cylinder bottom 12 from still suffering from a small amount of water leakage, therefore logical
The gap setting sealing element between cylinder barrel 10 and cylinder bottom 12 is crossed, the sealing to cylinder barrel 10 and cylinder bottom 12 is formed, avoids water
Leakage, is conducive to the stability and reliability that lifting jack 1 uses.
In the above-described embodiments, any of the outer peripheral surface of cylinder bottom 12, inner peripheral surface of cylinder barrel 10 are equipped with groove, or
The outer peripheral surface of cylinder bottom 12 and the inner peripheral surface of cylinder barrel 10 are respectively equipped with mutual corresponding groove, and sealing element is set in groove, has in this way
Conducive to the convenience of the installation of lift-off seal part, sealing element is avoided to fall off.
The embodiment of second aspect of the present invention provides a kind of hydraulic support, including frame body 20；Appoint in above-mentioned first aspect
The jack 1 using aqueous medium of one embodiment, jack 1 are connected with frame body 20.
In this embodiment, by using the jack 1 using aqueous medium of any of the above-described embodiment, to be provided with
Whole beneficial effects of above-described embodiment, details are not described herein.
According to the carried bottom jack using aqueous medium for the specific embodiment that the application proposes, by the same cylinder barrel of cylinder bottom 12
10 using being threadedly coupled, so that cylinder bottom 12 is detachable；And cylinder bottom 12 is subjected to preservative treatment with cylinder barrel 10 respectively, to avoid water Jie
The corrosion of confrontation cylinder barrel 10, cylinder bottom 12.
As shown in Figure 1, cylinder bottom 12 carries out preservative treatment, cylinder barrel 10 carries out preservative treatment, and cylinder bottom 12 is then packed into cylinder barrel
In 10.
The present invention has the following advantages that；
1) it can guarantee that the position contacted with aqueous medium all carries out preservative treatment；
2) cylinder bottom is detachable, will not destroy erosion resistant coating.
