Abstract
The invention discloses a multi-rod balance jack which comprises a hydraulic cylinder body and a hydraulic cylinder cover, wherein a piston is arranged in the hydraulic cylinder body and is connected with the inner wall of the hydraulic cylinder body in a sliding manner; a plurality of thin piston rods are arranged on the piston; a plurality of through holes are formed in the hydraulic cylinder cover; the positions of the multiple through holes correspond to those of the multiple thin piston rods; a groove is formed in the bottom of the hydraulic cylinder body. Due to the mode, the multi-rod balance jack is simple and reasonable in structure and is relatively good in balance performance during use.
Description
Technical field
The present invention relates to technical field of jacks, particularly relate to a kind of many bars balance jack.
Background technology
Hydraulic jack, also known as oil jack, is that a kind of plunger or hydraulic actuating cylinder of adopting lifts the jack of part as rigid top, simple structure, lightweight, be easy to carry, conveniently moving.
The piston rod of current hydraulic jack is all single bars, and be positioned at middle part, it is not good that extraordinary circumstances use balance.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of many bars balance jack, simple and reasonable, uses and has good balance quality.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of many bars balance jack, comprise: hydraulic cylinder and hydraulic cylinder, described hydraulic cylinder inside is provided with piston, described piston and hydraulic cylinder inwall sliding block joint, described piston is provided with many fine work stopper rods, and described hydraulic cylinder has multiple through hole, the position of described multiple through hole is corresponding with the position of multiple fine work stopper rod, has a groove bottom described hydraulic cylinder.
In a preferred embodiment of the present invention, described multiple through hole is evenly covered with hydraulic cylinder.
In a preferred embodiment of the present invention, the top adhesive of described fine work stopper rod has rubber pad.
The invention has the beneficial effects as follows: the present invention's many bars balance jack, simple and reasonable, use and there is good balance quality.
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 the present invention's many bars balance jack one preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1, hydraulic cylinder, and 2, hydraulic cylinder, 3, piston, 4, fine work stopper rod, 5, through hole.
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:
A kind of many bars balance jack, comprise: hydraulic cylinder 1 and hydraulic cylinder 2, described hydraulic cylinder 1 inside is provided with piston 3, described piston 3 and hydraulic cylinder 1 inwall sliding block joint, described piston 3 is provided with many fine work stopper rods 4, and described hydraulic cylinder 2 has multiple through hole 5, the position of described multiple through hole 5 is corresponding with the position of multiple fine work stopper rod 4, described multiple through hole 5 is evenly covered with hydraulic cylinder 2, by multiple fine work stopper rod 4, can obtain better balance support performance.
Bottom described hydraulic cylinder 1, there is a groove, when jack lifting insufficient height, the supports such as steel pipe can be added at groove.
The top adhesive of described fine work stopper rod 4 has rubber pad, avoids fine work stopper rod 4 pairs of supported objects to cause damage.
The invention has the beneficial effects as follows: the present invention's many bars balance jack, simple and reasonable, use and there is good balance quality.
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.
