Abstract
The utility model relates to a novel second class pressure jack of a piston pump, and comprises a jack and a piston pump inside which a reversing device for the alternating motion of a piston is provided. The piston pump can externally connect to an air supply with little air pressure. The air supply can reach to the 300 to 800 normal atmosphere after the effect of the piston pump, thus meeting the working needs of all kinds of the oil jack and can reduce the labor intensity, improve the work efficiency and ensure the work security. The utility model has simply structure, reasonable design and low cost.
Description
The utility model relates to a kind of novel piston pump secondary pressurization jack, jack is a machine manufacture, repairing waits the indispensable instrument of equipment industry, it uses extensively, but most hydraulic type jack is in use still based on manually, it needs lever is inserted in the crank of hydraulic type jack, oil in the reciprocating oil pump carries out work, therefore when the jacking load, need pay bigger muscle power, and adopt lever owing to manipulate the hydraulic type jack, the necessary operations space is big, during operation generally all under weight, make the operator be difficult for observing the situation that the load of hydraulic type jack is risen, danger factor are a lot.
The purpose of this utility model is in order to overcome the shortcoming of above manual hydraulic type jack, designs a kind of novel piston pump secondary pressurization jack that can external source of the gas process oil pressure type jack.
The purpose of this utility model is achieved through the following technical solutions, novel piston pump secondary pressurization jack, it is made of hydraulic type jack and piston pump, in piston pump, be provided with the reciprocating motion of the pistons reversing arrangement, reversing arrangement is by the commutation chamber, reverse lever, reverse wheel, the dovetail slide block, chute, mountain font slide block, spring is formed, reverse lever one end flexibly connects and is fixed on the reverse lever bearing of piston push rod, the reverse lever other end is provided with the reverse wheel of flexible connection, reverse wheel leans against on the sidewall of commutation chamber on one side, another side upwards withstands mountain font slide block, reverse wheel axle center prolongation on one side is installed in the chute, and chute is opened on the dovetail slide block.
Owing to adopted above technical scheme; it can the less source of the gas of external air pressure; after the piston pump effect, reach 300-800 standard atmosphere,, make full use of existing various model Air compressors to satisfy the job requirement of various types of hydraulic type jacks; it can reduce labour intensity; increase work efficiency, the protection safety of operation, it is simple in structure; reasonable in design, low cost of manufacture.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model scheme drawing.
Fig. 2 is the utility model piston pump profile scheme drawing.
Fig. 3 is the utility model piston pump inner structure scheme drawing.
Fig. 4 is Fig. 3 lateral plan.
Structural representation when Fig. 5, Fig. 6 work for the utility model.
See accompanying drawing, novel piston pump secondary pressurization jack, it is made of jack and piston pump etc., in piston pump, be provided with the reciprocating motion of the pistons reversing arrangement, reversing arrangement is by commutation chamber 7, reverse lever 6, reverse wheel 5, dovetail slide block 4, chute 3, mountain font slide block 1 and spring 2 are formed, reverse lever 6 one ends flexibly connect and are fixed on the reverse lever bearing 8 of piston push rod (the oil pump heart) 9, piston push rod (the oil pump heart) 9 one end captive joint pistons 10, piston 10 is provided with seal ring 11, reverse lever 6 other ends are provided with the reverse wheel 5 of flexible connection, reverse wheel 5 leans against on the sidewall of commutation chamber 7 on one side, reverse wheel 5 another sides upwards withstand mountain font slide block 1, spring 2 is installed in the mountain font slide block 1, reverse wheel 5 axle center 19 prolongations on one side is installed in the chute 3, chute 3 is opened on dovetail slide block 4, cylindrical ventilation push rod 18 1 ends are captiveed joint with dovetail slide block 4, the other end is slidingly mounted in the ventilation rod bush 17 that is located at housing 12 outsides, the ventilation push rod has 2 ventilation orifices 14,15 and 2 groove mouths 16 on 18 two ends, and admission port 13 is fixed on the ventilation bar overcoat 17.
During use, source of the gas enters piston left chambers 10 through admission port 13 by ventilation bar 18 1 end apertures 15, promoting piston 10 moves right, the groove mouth 17 of residual air on the other end on the ventilation bar 18 discharged in piston 10 right ventricles, at piston 10 simultaneously to right lateral, the bearing 8 drive reverse levers 6 that are located on the piston push rod (the oil pump heart) 9 move right simultaneously, reverse lever 6 drives reverse wheel 5 and moves up along commutation chamber 7 sidewalls, the mountain font slide block 1 that reverse wheel 5 upwards withstands moves up simultaneously, this moment, spring 2 was compressed, the this moment of the motion in chute 3 of reverse wheel 5 axle center 19 prolongations, dovetail slide block 4 is motionless, when 8 motions of reverse lever bearing surpass balance position, and reverse wheel 5, reverse lever 6 is under spring 2 effects, reverse lever 6 rotates around bearing 8, and promptly reverse wheel 5 is swung to lower from eminence, and axle center 19 prolongations that are installed in the reverse wheel 5 in the chute 3 are simultaneously stirred dovetail slide block 4 and turned left from the right side and stir, and promote ventilation bar 6 to left movement, form the iterative motion of piston with this.Finish pump oil process thus to jack.
