Abstract
The invention discloses a rack jack. The rack jack comprises a base, a mechanical body and a top supporting column, wherein a first driving rod, a second driving rod and a third driving rod are arranged on three side vertical faces of the mechanical body in a rotatable mode respectively, the first driving rod, the second driving rod and the third driving rod are arranged on the same horizontal plane, and the second driving rod is arranged perpendicular to the first driving rod and the third driving rod. Due to the fact that the rack jack can be driven by the three driving rods on the side vertical faces at the same time, the action range of driving force is broadened, and supporting force generated by the rack jack can be greatly increased.
Description
Technical field
The present invention relates to a kind of jack, or rather, is a kind of rack-jack.
Background technology
Rack-type jack is called again rack-and-pinion track lifting machine, rack-jack, and tonnage has the kinds such as 1 ton, 10 tons, 41 tons, compact conformation, rationally utilize drive spindle that hock is moved up and down, be linked with determining hock, promote to support fore-set and rise or decline, play weight lifting thereupon.It is one of manual type lifting gear kind.
Rack-type jack in technology is mainly to operate by a drive spindle at present, and operating mode is single, and the direction of application force is restricted in actual applications, and produced simultaneously bearing force is less.
Summary of the invention
The present invention solves the existing technical matters of prior art, thereby provide a kind of, can apply propulsive effort from three different directions, can produce the jack of larger bearing force.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of rack-jack, comprise a base, a basic machine and a support fore-set, rotating one first drive spindle, one second drive spindle and one the 3rd drive spindle of being provided with respectively on three side elevations of described basic machine, the first described drive spindle is connected with described basic machine by one first clamshell, the second described drive spindle is connected with described basic machine by one second clamshell, and the 3rd described drive spindle is connected with described basic machine by one the 3rd clamshell.
As preferred embodiment of the present invention, the first described drive spindle, the second drive spindle and the 3rd drive spindle are in same level, and the setting party of the second described drive spindle is to perpendicular with the first drive spindle, the 3rd drive spindle respectively.
As preferred embodiment of the present invention, described support fore-set is that alloy steel is one-body molded.
Because rack-jack of the present invention can be driven by three drive spindles of side elevation simultaneously, expanded the sphere of action of propulsive effort, the bearing force that simultaneously makes jack produce improves greatly.This rack-jack is simple in structure, easy to use, practical.
accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of jack of the present invention;
Fig. 2 is the perspective view of the jack driving bar in Fig. 1, is now another visual angle;
the specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides a kind of can driving from three different directions, and the jack that is greatly improved of bearing force.
As depicted in figs. 1 and 2, a kind of rack-jack, comprise a base 1, a basic machine 2 and a support fore-set 3, rotating one first drive spindle 41, one second drive spindle 51 and one the 3rd drive spindle 61 of being provided with respectively on three side elevations of described basic machine 2, the first described drive spindle 41 is connected with described basic machine 2 by one first clamshell 42, the second described drive spindle 51 is connected with described basic machine 2 by one second clamshell 52, and the 3rd described drive spindle 61 is connected with described basic machine 2 by one the 3rd clamshell 62.
This jack the first drive spindle 41, the second drive spindle 51 and the 3rd drive spindle 61 in same level, the setting party of the second described drive spindle 51 is to perpendicular with the first drive spindle 41, the 3rd drive spindle 61 respectively.
This rack-jack, supports the fore-set 3 alloy steel material manufacture that is formed in one and forms.
Because this rack-jack can be driven by three drive spindles of side elevation simultaneously, expanded the sphere of action of propulsive effort, the bearing force that simultaneously makes jack produce improves greatly.This rack-jack is simple in structure, easy to use, practical.
Below only with an embodiment, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more functional module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
