Abstract
The invention discloses a hydraulic jack. Flanges are manufactured at two ends of a hydraulic cylinder of the hydraulic jack based on the working principle of the existing hydraulic jack, a plurality of bolt holes are evenly formed in the flanges, a pressurizing cylinder is arranged on the flange at the bottom, a small piston is arranged in the pressurizing cylinder, a support is manufactured on the hydraulic cylinder at the waist portion, a handle is movably hinged to the support and is connected with the small piston through a connection rod, a main piston is arranged in the hydraulic cylinder, and an adjusting screw is arranged in the middle of the main piston. The hydraulic jack has the advantages of adapting to installation and fixation of various sites and being convenient to use.
Description
Technical field
The present invention relates to a kind of jack, a kind of hydraulic jack specifically, belongs to hardware & tools technical field.
Background technology
Hydraulic jack is a kind of conventional hardware & tools, although because specification, the brand of jack are not quite similar, but be all structurally machine-made conventional confguration pattern, thus, cause the inconvenience in many uses, for example: if desired jack is fixed on while use on some matrixes or framework, owing to installing normally, many troubles are brought, and for example: sometimes need that jack is fixed on to any locus and use, because existing jack is without corresponding fixed position, also cause using having many troubles.
Summary of the invention
The object of the invention is to: for the existing above-mentioned defect of existing hydraulic jack, the invention provides a kind of novel hydraulic jack, the present invention realizes the technical scheme that above-mentioned purpose adopts: this kind of hydraulic jack comprises: hydraulic cylinder, main piston, regulate screw mandrel, pressurized cylinder, valve piston, connecting rod, handle, flange, bracing frame, bolt hole, in the principle of work of existing hydraulic jack, two ends at the hydraulic cylinder of hydraulic jack are shaped with flange, uniformly on flange be shaped with some bolts hole, on the flange of bottom, pressurized cylinder is set, valve piston is set in pressurized cylinder, waist location at hydraulic cylinder is made bracing frame, on bracing frame, be hinged with actively a handle, handle is connected with valve piston by connecting rod, in hydraulic cylinder, be provided with main piston, the centre of described main piston is provided with adjusting screw mandrel.
beneficial effect
The present invention, because flange is made at the two ends at main hydraulic cylinder, makes some tapped bore on flange, so the installation that has facilitated hydraulic jack to withstand on various places is fixed, has advantages of easy to use.
accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention;
Shown in figure: 1, hydraulic cylinder; 2, main piston; 3, regulate screw mandrel; 4, pressurized cylinder; 5, valve piston; 6, connecting rod; 7, handle; 8, flange; 9, bracing frame; 10, bolt hole.
the specific embodiment
In the drawings, this kind of hydraulic jack comprises: hydraulic cylinder 1, main piston 2, regulate screw mandrel 3, pressurized cylinder 4, valve piston 5, connecting rod 6, handle 7, flange 8, bracing frame 9, bolt hole 10, in the principle of work of existing hydraulic jack, be shaped with flange 8 at the two ends of the hydraulic cylinder 1 of hydraulic jack, uniformly on flange 8 be shaped with some bolts hole 10, on the flange 8 of bottom, pressurized cylinder 4 is set, at the interior valve piston 5 that arranges of pressurized cylinder 4, make bracing frame 9 at the waist location of hydraulic cylinder 1, on bracing frame 9, be hinged with actively a handle 7, handle 7 is connected with valve piston 5 by connecting rod 6, in hydraulic cylinder 1, be provided with main piston 2, the centre of described main piston 2 is provided with and regulates screw mandrel 3.
