Abstract
The utility model discloses a jack fixed in grassland. The jack comprises a base, wherein a supporting sheet is arranged below the base; at least two sharp objects are arranged below the supporting sheet; one side of the base is hinged with the supporting sheet; the other side face of the base is hinged with a hook; and a buckle for fixing the hook is arranged on the supporting sheet. The jack can enter the grassland conveniently through the sharp objects, the jack can be overturned along a hinging point by opening the buckle, and the distance between the overturned jack and the objects is prolonged, so that the jack can be knocked conveniently into the grassland for fixing by a road tool. The jack can be applied to grassland, and is convenient to fix.
Description
Technical field
The utility model belongs to a kind of jack that is fixed in the meadow.
Background technology
Jack is that a kind of the top with rigidity lifted part as equipment, the light little weight-lifting equipment of jacking weight in stroke by top bracket or bottom claw.Can be divided into 3 kinds of tooth bar jack, lifting screw and hydraulic jacks by architectural feature.Jack is the simplest weight-lifting equipment of a kind of lifting highly little (less than 1m), and it has two kinds of mechanical type and fluid pressure types.The mechanical type jack has rack-and-pinion and spiral two kinds again, because hoisting capacity is little, the operation effort generally only is used for flight-line maintenance work, and is inapplicable in repairing the bridge process.Fluid pressure type jack structure compactness, stable working has self-locking action, so use extensively.Its shortcoming is that lifting is highly limited, and lifting velocity is slow.The kind of car jack can be divided into four kinds of tooth bar jack, lifting screw and hydraulic jack and inflatable jacks.When using jack on the meadow, because jack need be placed on above the haystack, jack is in slippage easily under stressing conditions on the meadow.And, since jack with need that spacing is not big especially between the object of jack-up, want to use other stage properties that jack is struck down fixing also suitable inconvenience.Need a kind of jack that can use on the meadow, and this jack is convenient fixing.
Summary of the invention
The utility model provides a kind of and can use on the meadow and convenient fixing jack at the prior art deficiency.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of jack that is fixed in the meadow, comprise base, described base below is provided with supporting blade, be provided with at least two tip shape objects below the described supporting blade, have a side and supporting blade hinged in the described base, described base another side is hinged with hook, and described supporting blade is provided with the buckle for fixing described hook.The tip shape object makes things convenient for jack to enter down in the meadow, opens buckle, can be with the overturning of jack side direction along hinge-point, translate into that spacing becomes big between back jack and the object, convenient use stage property to beat jack that jack is entered in the meadow is fixing.
In the technique scheme, be provided with three triangle tip shape objects, described three tip shape object distributions triangular in shape below the described supporting blade.Be under the prerequisite to save cost, using three tip shape objects triangular in shape is the most firm modes of fixing: its soil layer that enters below the grass layer is more laborsaving on the one hand, and on the other hand, it has the plane that prevents that supporting blade from moving.
In the technique scheme, described jack base bottom surface is provided with magnet, and described supporting blade is provided with magnet.Make fixing more firm of jack and supporting blade.
In the technique scheme, described jack base bottom surface has anti-skid structure.Increase the friction force between jack bottom surface and the supporting blade, prevent that jack from skidding.
The utility model compared with prior art has following beneficial effect: the utility model arranges supporting blade and is used for supporting jack, the tip shape object is set under the supporting blade makes things convenient for jack to enter down in the meadow.Be under the prerequisite to save cost, using three tip shape objects triangular in shape is the most firm modes of fixing.Hinge-point is set can be with the overturning of jack side direction, translates into that spacing becomes big between back jack and the object, convenient use stage property to beat jack that jack is entered in the meadow is fixing.After jack recovered former state, buckle can be fixed jack.Jack bottom surface and supporting blade all arrange magnet, make fixing more firm of jack and supporting blade.The jack base bottom surface is anti-skid structure, increases the friction force between jack bottom surface and the supporting blade, prevents that jack from skidding.

The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1, Fig. 2, a kind of jack that is fixed in the meadow, comprise first hold-down arm 1, second hold-down arm 2, the 3rd hold-down arm 3, the 4th hold-down arm 4, described first hold-down arm 1 and the 3rd hold-down arm 3 are flexibly connected by first active connection part 17, described second hold-down arm 2 and the 4th hold-down arm 4 are flexibly connected by second active connection part 18, first active connection part 17 and second active connection part 18 are all passed by a screw rod 7, described first hold-down arm 1 and 2 support and connection place of second hold-down arm are provided with base 5, and described the 3rd hold-down arm 3 and the 4th hold-down arm 4 junctions are provided with pallet 6.
Described base 5 belows are provided with supporting blade 8, are provided with three triangle tip shape objects 9, described three tip shape objects, 9 distributions triangular in shape below the described supporting blade 8.Be under the prerequisite to save cost, using three tip shape objects 9 triangular in shape is the most firm modes of fixing: its soil layer that enters below the grass layer is more laborsaving on the one hand, and on the other hand, it has the plane that prevents that supporting blade from moving.9 on tip shape object is relatively sharper, makes things convenient for jack to enter down in the meadow.
There are a side and supporting blade 8 hinged in the described base 5, described base 5 side corresponding with hinged is hinged with hook 10, hook 10 can fluctuate, and described supporting blade 8 is provided with the buckle 11 for fixing described hook 10, and hook 10 can collude at buckle 11 fixes jack.
Described jack base 5 bottom surfaces are provided with magnet, and described supporting blade 8 is provided with magnet, are placed on during jack on the supporting blade 8, and magnet is inhaled more firm that jack and supporting blade 8 are fixed mutually.
Described jack base 5 bottom surfaces have anti-skid structure, and anti-skid structure increases the friction force between jack base 5 and the supporting blade 8, prevents that jack from skidding.
On the meadow, only jack to be placed up and be difficult to placement steadily, a large amount of careless stems and the existence of root also are difficult to hand jack to be pressed the earth the inside and fix.The method that use is beaten can say that jack is easily fixing, after but jack is put into below the object, it is less that spacing between jack and the object just becomes, and the scope of beaing is just very little, is difficult to firmly, open buckle 10 this moment, can be with the overturning of jack side direction along hinge-point, translate into that spacing becomes big between back jack and the object, the scope of beaing just becomes big, exert all one's strength easily, make things convenient for jack fixing in the meadow.
