Abstract
The utility model discloses an automobile automatic jack. A hydraulic oil tank is arranged on an automobile chassis, a hydraulic oil pump is arranged on the hydraulic oil tank, a hydraulic oil cylinder A, a hydraulic oil cylinder B, a hydraulic oil cylinder C and a hydraulic oil cylinder D are communicated with the hydraulic oil tank through hydraulic oil pipes, the hydraulic valve is arranged on the hydraulic oil pipes, a control switch is connected with the hydraulic oil pump, each hydraulic oil cylinder is provided with a propping rod, and springs are arranged between the hydraulic oil cylinders and the propping rods. The utility model installs the four hydraulic oil cylinders on an automobile chassis. When a tyre needs to be changed, drivers only need to press the control switch arranged in a control cab to start the hydraulic pump, and the hydraulic pump provides the hydraulic motive power for pressing hydraulic oil in the hydraulic oil tank into the hydraulic oil cylinders through the hydraulic oil pipes for realizing the up-and-down movement of the propping rods arranged on the hydraulic oil cylinders, so the automobile chassis is propped up, and the tyre can be conveniently changed. When the automobile is parked, the automobile can be propped up from the ground through the control switch by the propping rods of the hydraulic oil cylinders, and the anti-theft effect can be realized.
Description
Technical field:
The utility model relates to a kind of hydraulic jack, relates in particular to the automatic jack of automobile of a kind of tire patching convenience, safe antitheft.
Background technology:
Jack is the highly little simple weight-lifting equipment of a kind of lifting, jack is applied in the maintenance of vehicle widely, jack of the prior art all is back and forth to pull crank by hand, realize lifting, not only time-consuming, effort, and automobile in the open air or the ground unfairness, blow out suddenly in the place on slope, can't use jack to keep in repair, invented vehicle-mounted jack in the prior art, cardinal principle is for to be installed in hydraulic ram on the car chassis, utilizing jack with car chassis jack-up, thereby conveniently change tire, is example with disclosed 200620133704.7 patents of State Intellectual Property Office, though this patent can solve and change the tire problem on the various road surfaces, but because of hydraulic ram and jack are installed in the car chassis bottom surface, in the hill path and during the relatively poor road traveling of road conditions, potential safety hazard is brought on the partial devices ground of can colliding with.
Summary of the invention:
The utility model provides the lifting gear hydraulic jack of a kind of tire patching convenience, safe antitheft at the deficiencies in the prior art.
For realizing the above object, the technical solution adopted in the utility model is:
The automatic jack of automobile is made up of car chassis, hydraulic reservoir, hydraulic oil pump, hydraulic valve, hydraulic oil pipe, hydraulic ram A, hydraulic ram B, hydraulic ram C, hydraulic ram D, push rod, master cock, spring; Hydraulic reservoir is installed in above the car chassis, hydraulic oil pump is installed on the hydraulic reservoir, hydraulic ram A, hydraulic ram B, hydraulic ram C, hydraulic ram D communicate with hydraulic reservoir by hydraulic oil pipe, hydraulic valve is installed on the hydraulic oil pipe, master cock is connected with hydraulic oil pump, each hydraulic ram is provided with push rod, is provided with spring between hydraulic ram and the push rod.
The utility model utilizes four hydraulic rams to be installed in above the car chassis, when changing trains tire if desired, only need press the master cock in the operator's compartment, the primer fluid press pump, Hydraulic Pump provides hydrodynamic that hydraulic oil in the hydraulic reservoir is entered hydraulic ram by hydraulic oil pipe, realize the dipping and heaving of hydraulic ram upper ejector pin, thereby, conveniently change tire car chassis jack-up; If during with automobile parking, can pass through master cock, utilize the hydraulic ram push rod that automobile jack-up is above the ground level, even opening car door, the thief drives automobile, also automobile can't be driven away, also play anti-theft feature.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is a utility model hydraulic ram partial enlarged drawing;
The specific embodiment:
As shown in Figure 1 and Figure 2, the automatic jack of automobile is made up of car chassis 1, hydraulic reservoir 2, hydraulic oil pump 3, hydraulic valve 4, hydraulic oil pipe 5, hydraulic ram A6, hydraulic ram B7, hydraulic ram C8, hydraulic ram D9, push rod 10, master cock 11, spring 12; When automobile need change tire, open master cock 11, primer fluid press pump 3, Hydraulic Pump 3 provides hydrodynamic that hydraulic oil in the hydraulic reservoir 2 is entered hydraulic ram A6, hydraulic ram B7, hydraulic ram C8, hydraulic ram D9 respectively by hydraulic oil pipe 5, hydraulic ram upper ejector pin 10 is constantly descended,, be convenient for changing tire car chassis 1 jack-up, car chassis 1 is above the ground level, plays anti-theft feature; If tire changing finishes; just close hydraulic valve 4; make the interior hydraulic oil of hydraulic ram get back to hydraulic reservoir 2; thereby push rod 10 is gone back up in the hydraulic ram; be provided with spring 12 between hydraulic ram and the push rod 10 simultaneously, utilize the effect of automatically reseting of spring 12, when avoiding the interior hydraulic oil of hydraulic ram to omit; push rod 10 runs out of steam and lands automatically, plays the safety guard-safeguard effect.
The utlity model has the advantages such as easy to operate, simple in structure, convenient and practical, safe antitheft, have great promotional value.
