Abstract

The utility model relates to a double-purpose device for a hand vehicle oil pump and a tyre inflation machine, which mainly comprises a motor; the front end and the back end of a motor rotating shaft is pivoted with a crank shaft and a radiation fan. The pin of the crank shaft is fixed with a rocking arm, and the rocking arm is used for driving two pistons having the same shaft with a gas pressure and oil pressure double cylinder to move towards a front part and a back part. Two cylinders are convenient to form a gas pressure and oil pressure pump. The utility model can simultaneously carry out the extracting of oil materials and the inflating of the tyre integrally.

Description

Two purpose device for hand vehicle oil pump and tyre inflation machine

The utility model is about a kind of vehicle oil pumping and tyre inflation dual-purpose apparatus, especially the piston propelling movement of synchronous one is done in a kind of mat single motor drive of finger pneumatic pump, the coaxial axle center of oil pressure pump twin-tub, and produce oil pumping and the effect of inflating, be convenient for changing machine oil, replenish a job such as oil plant and tyre inflation.

In the general car maintaining work, mainly all include more one of change engine oil, though seen that on the market pumping unit apparatus is arranged, its body is huge to be for the special environment that is used in the automobile maintenance, for ordinary consumer, still there is not the handy type that makes things convenient for the Consumer to use the voluntarily machine of changing oil.

And Tire Inflation System, early existing on the market simple pedal and electronic two kinds of the formulas of inflating automatically, manually the pedal inflator is abandoned by the modern especially already, but electronic automatic aerator is not have simultaneously to supply the device of oil pumping, thereby a kind of oil pumping and dual-purpose device of inflating of having concurrently, its unique value is arranged in fact.

Main purpose of the present utility model promptly provides a kind of portable vehicle pumping unit and tyre inflater dual-purpose apparatus, and the design that this device of mat is special can be served as the oil pressure pump oil pumping simultaneously more to renew machine oil, reaches pneumatic pump to automatic tyre air inflation.

Secondary objective of the present utility model promptly provides a kind of portable handy type vehicle pumping unit and tyre inflater dual-purpose apparatus, and it can move by different air pressure, the oil pressure pumps of a mat one electric motor outputting power conduction simultaneously, uses voluntarily for the Consumer.

And above-mentioned purpose and other advantage can realize by portable vehicle pumping unit of the present utility model and tyre inflater dual-purpose apparatus.It mainly includes a jacket, an electric motor outputting rotary power, and its output revolving shaft front end is pivoted with a crankshaft, and this crank of mat changes to such an extent that the priming push shaft of setting up piston seesaws, make to form a pneumatic pump and an oil pressure pump, wherein,

This push shaft trailing edge is provided with pneumaticpiston, and leading edge rod end external loop diameter is equiped with piston ring as hydraulic piston, after one pneumatic cylinder is embedded at oil hydraulic cylinder, separate between two cylinders and with an oil sealing, when the motor start also converts straight reciprocating motion to because of rocking arm indirectly, pneumaticpiston and hydraulic piston are to compress start synchronously, respectively at forming pneumatic pump and oil pressure pump in its cylinder chamber.

The utility model device at first is provided with an electric motor, and the motor shaft rear end drives a radiation fan with heat radiation, and the rotating shaft front end is pivoted with a crankshaft; One rocking arm, one end pin is fixed on the crankshaft, the other end links a last cylinder axle, in this cylinder axle front end ring set one graphite annulus is arranged, and its piston ring of mat is that graphite material is made, during with the oil-containing oil pressure casing wall seal compression of special powder metallurgy system, can be more high temperature resistant and do not cause the piston cylinder that contracts; The rear end of cylinder axle is provided with big piston in addition, fills out between the rear end of oil hydraulic cylinder and pneumatic cylinder two cylinders and establishes an oil sealing; The pressure of taking out that is made of two one-way valves is connected with respectively in pneumatic cylinder and oil hydraulic cylinder, to form pneumatic pump and oil pressure pump, because its air pressure, oil pressure twin-tub axle center are made as consubstantiality, so the output of mat electric motor produces the function of pneumatic pump and oil pressure pump, to realize oil pumping, inflation two-shipper one.

For making the juror with advantage further understanding be arranged to the utility model structure, below will cooperate graphic explanation by a specific embodiment, it is done more detailed the elaboration.

Fig. 1 is the utility model embodiment's a stereo appearance figure.

Fig. 2 analyses and observe view for the utility model embodiment one.

Fig. 3 constructs decomposing schematic representation for the utility model embodiment.

See also Fig. 1,2,3, the utility model device comprises that mainly a tool carrying handle external form slightly is the housing 10 of kettle type, one electric motor 11, the front end of its output revolving shaft crankshaft 12 that is pivoted, the rear end then is pivoted a fan 13 with the rotation heat radiation, kelly latch on the crankshaft 12 links a rocking arm 14; rocking arm 14 1 ends are fixed in cylinder axle 15 with shank 141 pin again; compression before and after doing by the draw pulling cylinder axle 15 that shakes wall 14; and cylinder axle 15 tail ends are provided with the beam ring 162 that a pneumaticpiston 16, one O shapes ring 161 and coupling conform to copper packing and are installed on the pneumaticpiston 16 ring footpaths; In leading edge axle head hydraulic piston 17 ora terminalis of cylinder axle 15, utilize the solid graphite annulus 172 of screw 171 installing spiral shells again, be combined to form the axis central part of double-piston consubstantiality cylinder axle of the present utility model with this.

Setting and be placed on the cylinder sleeve body structure that the cylinder axle produces pumping pressure, is to be assembled by air pressure cylinder sleeve 18, oil sealing 19, pneumatic pump body 20, oil

pressure cylinder sleeve

21 and 22 series connection of oil pressure pump body; Before wherein oil pressure pump body 22 is installed on, be equiped with two one-

way valves

221 and 222 in it, oil pressure cylinder sleeve 21 continue be embedded in after, and its cylinder body hollow portion is to connect to aforementioned two one-way valves 221, in 222 the hydraulic chamber, in oil pressure cylinder sleeve 21 trailing edges is encapsulation pneumatic pump body 20, also have two one-way valves 201 in the body, 202, air pressure cylinder sleeve 18 is embedded at pneumatic pump body 20 rear ends, one oil sealing 19 is placed in the pneumatic pump body 20 and between air pressure cylinder sleeve 18 and the oil pressure cylinder sleeve 21, to separate air pressure and oil pressure pump pressure chamber, on oil pressure pump, more be provided with a conduit again and be connected to the oil suction inlet, make when the oil extruding is excessive, can be back to the ingress thus and prevent that oil impregnate from taking place.

In sum, the utility model device is that motor of mat seesaws through the axle that a crankshaft drives the synchronous one of twin-tub, also be provided with a pneumaticpiston and a hydraulic piston on its axle, cooperate gas, oil cylinder to put the hitch pump structure, must produce pumping into of air pressure and oil pressure simultaneously pumps, and be provided with drain mast and be connected between oil hydraulic cylinder and the former inlet, prevent leakage of oil; This oil pressure cylinder sleeve is that special powder metallurgy is made again, piston head is equipped with special graphite annulus, must make the long-time start cylinder phenomenon that also do not contract, and is can a machine carry out waste oil simultaneously to extract or inflation of tire according to said apparatus, have novelty, creativeness and practicability are undoubtedly.
