Abstract

The invention discloses a jack with the adjustable base height. The jack comprises a first fixed seat, a hydraulic cylinder and a hydraulic pump. The hydraulic cylinder and the hydraulic pump are arranged on the first fixed seat. A second fixed seat is arranged below the first fixed seat and provided with a multi-stage hydraulic supporting rod. The top of the multi-stage hydraulic supporting rod makes contact with the bottom of the first fixed seat. Guide posts pointing to the upper portion are vertically arranged at the four corners of the second fixed seat respectively. The first fixed seat is provided with guide sleeves corresponding to the guide posts respectively. The multi-stage hydraulic supporting rod is provided with a locking switch. In this way, by means of the jack with the adjustable base height, the multi-stage hydraulic supporting rod can be compressed by means of pressing the first fixed seat downwards, the height of the first fixed seat is changed accordingly, the lifting height of the hydraulic cylinder is changed, use is more flexible, and working efficiency is improved.

Description

The jack that a kind of substructure height is adjustable
Technical field
The present invention relates to hoisting device field, particularly relate to the jack that a kind of substructure height is adjustable.
Background technology
Jack is a kind of common weight-lifting equipment, and it is easy and simple to handle, and floor area is little, convenient transportation, therefore, uses more extensive.The volume of Normal hydraulic jack is little, but the weight of lifting is but not little, uses very general in Automobile Service field.
The maximum lifting strokes of jack is definite value; in the actual process used; often can run into the inadequate problem of stroke; the method of usual employing increases cushion block in the bottom of jack; but increase the stability that cushion block easily affects jack, and the thickness of cushion block is also difficult to adapt to requirements of one's work, is difficult to change height flexibly; bad adaptability, reduces work efficiency.
Summary of the invention
The technical matters that the present invention mainly solves is to provide the adjustable jack of a kind of substructure height, changes the height of base, increases work efficiency.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide the jack that a kind of substructure height is adjustable, comprise: the first permanent seat, hydraulic actuating cylinder and Hydraulic Pump, described hydraulic actuating cylinder and Hydraulic Pump are separately positioned on the first permanent seat, the second permanent seat is provided with below described first permanent seat, described second permanent seat is provided with a multistage hydraulic strut bar, the top of described multistage hydraulic strut bar and the bottom connection of the first permanent seat touch, described second permanent seat, four angles are vertically installed with respectively the guidepost pointing to top, described first permanent seat is provided with orienting sleeve corresponding with guidepost respectively, described multistage hydraulic strut bar is provided with lockup switch.
In a preferred embodiment of the present invention, described guidepost is arranged at intervals with several positioning groove.
In a preferred embodiment of the present invention, be respectively arranged with outside described first permanent seat and extend perpendicularly in orienting sleeve and the binding bolt be connected with positioning groove, described binding bolt end is provided with turning handle.
In a preferred embodiment of the present invention, described Hydraulic Pump is hydraulic hand-pump or electric hydraulic pump.
In a preferred embodiment of the present invention, described Hydraulic Pump is connected with hydraulic actuating cylinder the driving carrying out being elevated.
The invention has the beneficial effects as follows: the jack that a kind of substructure height that the present invention points out is adjustable, first permanent seat is supported by multistage hydraulic strut bar, press down the first permanent seat, multistage hydraulic strut bar can be compressed, thus change the height of the first permanent seat, change the height of hydraulic actuating cylinder lifting, use more flexible, improve work efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of adjustable jack one preferred embodiment of a kind of substructure height of the present invention.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
The jack that a kind of substructure height is adjustable, comprise: the first permanent seat 3, hydraulic actuating cylinder 1 and Hydraulic Pump 2, described hydraulic actuating cylinder 1 and Hydraulic Pump 2 are separately positioned on the first permanent seat 3, described Hydraulic Pump 2 is connected with hydraulic actuating cylinder 1 driving carrying out being elevated, the height of the first permanent seat 3 determines the height of lifting, therefore needs the height of change first permanent seat 3 to increase Applicable scope.
Described Hydraulic Pump 2 is hydraulic hand-pump or electric hydraulic pump.Hydraulic hand-pump needs manual operation, but working space comformability is good, and the rapid operation of electric hydraulic pump, but to electric power, there is requirement, have necessarily restricted.
The second permanent seat 4 is provided with below described first permanent seat 3, described second permanent seat 4 is provided with a multistage hydraulic strut bar 8, the top of described multistage hydraulic strut bar 8 and the bottom connection of the first permanent seat 3 touch, described second permanent seat, 4 four angles are vertically installed with respectively the guidepost 5 pointing to top, described first permanent seat 3 is provided with orienting sleeve 6 corresponding with guidepost 5 respectively, described multistage hydraulic strut bar 8 is provided with lockup switch 81.The height of the first permanent seat 3 is supported by multistage hydraulic strut bar 8, and the first permanent seat 3 is parallel to be suspended on the second permanent seat 4, presses down the first permanent seat 3, can adjust to suitable operating altitude.
Described guidepost 5 is arranged at intervals with several positioning groove, and be respectively arranged with outside described first permanent seat 3 and extend perpendicularly in orienting sleeve 6 and the binding bolt 7 be connected with positioning groove, described binding bolt 7 end is provided with turning handle.The rotation of turning handle is convenient, can strengthen coordinating of binding bolt 7 and positioning groove, fix the height of the first permanent seat 3, the stability of lifting lifting.
In sum, the jack that a kind of substructure height that the present invention points out is adjustable, the height adjustment of the first permanent seat 3 is flexible, and applied widely, easy and simple to handle, durability is good, and working stability is high.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
