Abstract
The utility model discloses a novel hydraulic jack, including the running -board, the valve piston, little hydro -cylinder, the first, angelica grosseserrata on check valve stopper, big hydro -cylinder, check valve second, pressure sensor, safety cover, display, oil tank and drainage valve, running -board pass through the spring mounting and install the export at the oil return line who connects little hydro -cylinder and oil tank at valve piston upper surface, valve piston and the cooperation of little hydro -cylinder, check valve first, and check valve second is installed and is being connected little hydro -cylinder and the oil outlet pipeline's of hydro -cylinder export greatly, angelica grosseserrata stopper is installed at the top of angelica grosseserrata stopper with big hydro -cylinder cooperation, pressure sensor, pressure sensor with install outside the oil tank display on the safety cover and be connected, angelica grosseserrata surface beyond the great wall is equipped with height scale. The beneficial effects of the utility model are that: adopt novel hydraulic structure, be equipped with weighing displayer and height scale, can improve the range of application of jack.
Description
Technical field
This utility model is related to a kind of jack, more particularly to a kind of hydraulic jack.
Background technology
Jack is easily damaged because load is overweight in the market, easily makes very heavy pressurized unstable, causes to be held
Loading is dropped.Unprotected device outside jack, sealing property are bad, and hydraulic oil is easily revealed.Most of jack does not have
Standby weight display, it is impossible to enough show load weight, limit the application of some special occasions.
The content of the invention
The purpose of this utility model is aiming at the deficiency of prior art presence, there is provided hydraulic jack, adopts
Novel hydraulic structure, is equipped with weight display and altitude scale, it is possible to increase the range of application of jack.
A kind of hydraulic jack, is characterized in that：Including pedal, valve piston, small oil tank, check valve first, big piston,
Large tank, check valve second, pressure transducer, protective cover, display, fuel tank and bleeder valve, pedal are arranged on little by spring
Piston upper surface, valve piston are coordinated with small oil tank, and check valve first is arranged on the outlet of the oil return pipeline of connection small oil tank and fuel tank,
Check valve second is arranged on the outlet of the flow line of connection small oil tank and large tank, and the big piston is coordinated with large tank, pressure
Sensor is arranged on the top of big piston, and pressure transducer is connected with the display on protective cover on the outside of fuel tank, Radix Angelicae Dahuricae (Radix Heraclei Scabridi)
Outer surface is provided with altitude scale.
Description of the drawings
Accompanying drawing 1 is overall structure diagram of the present utility model.
In upper figure：Pedal 1, valve piston 2, small oil tank 3, check valve first 4, flow line 4.1, oil return pipeline 4.2, Radix Angelicae Dahuricae (Radix Heraclei Scabridi)
Plug 5, large tank 6, check valve second 7, pressure sensing 8, protective cover 9, display 10, fuel tank 11, bleeder valve 12.
Specific embodiment
This utility model is further described with reference to accompanying drawing 1：
This utility model includes pedal 1, valve piston 2, small oil tank 3, check valve first 4, big piston 5, large tank 6, unidirectionally
Valve second 7, pressure transducer 8, protective cover 9, display 10, fuel tank 11 and bleeder valve 12, pedal 1 are arranged on little work by spring
2 upper surfaces are filled in, valve piston 2 is coordinated with small oil tank 3, check valve first 4 is arranged on the oil return pipeline of connection small oil tank 3 and fuel tank 11
4.2 outlet, check valve second 7 are arranged on the outlet of the flow line 4.1 of connection small oil tank 3 and large tank 6, the big piston 5
Coordinate with large tank 6, pressure transducer 8 is arranged on the top of big piston 5, pressure transducer 8 is protected with being arranged on the outside of fuel tank 11
Display 10 on shield 9 connects, and 5 outer surface of big piston is provided with altitude scale.
When the device is used, pedal 1 is stepped down with foot first, move downward valve piston 2, check valve first 4 is closed
Close, check valve second 7 is opened, in small oil tank 3, hydraulic oil enters large tank 6, the hydraulic oil in large tank 6 by flow line 4.1
Small oil tank 3 cannot be back to, when foot lifting, check valve first 4 is opened, and check valve second 7 is closed, and the hydraulic oil in fuel tank 11 passes through
Oil return pipeline 4.2 is entered in small oil tank 3, and the pressure in large tank 6 is continuously increased 5 jack-up of big piston, the pressure on 5 top of big piston
Force transducer 8 is subject to the pressure of weight, data is passed to display 10 and shows weight, and the scale on 5 surface of big piston can show
Show lifting height, after lifting task is completed, open bleeder valve 12, the hydraulic oil in large tank 6 is back in fuel tank 11.
The invention has the beneficial effects as follows：There is provided hydraulic jack, novel hydraulic structure is employed, outfit is weighed aobvious
Show device and altitude scale, it is possible to increase the range of application of jack.
