Description

The portable two-purpose gas cylinder

The utility model relates to a kind of portable two-purpose gas cylinder.

General most of the middle-size and small-size charger of being sold on the market at present possesses a kind of function, promptly or just electric gas-filled or just manually inflation, electrical equipment mainly is an air compressor or with the inflator of the compressor for refrigeration transformation of the way, they can only use 220 volts of Ac, and general volume more greatly, heavier, price is also relatively more expensive.And artificial pump divides hand-operated and foot-operated two kinds, can to the wheel aerating of bicycle, motorcycle, though the both economical material benefit of this inflator, but effort relatively, the time of inflating required cost is also long.

The purpose of this utility model is that a kind of portable two-purpose gas cylinder will be provided, and this inflator can be electric gas-filled, can manually inflate again, and volume is little, in light weight, cheap, reliable performance, easy to use.

The purpose of this utility model is achieved in that by cylinder 7, motor 6, support 1, crank-connecting rod 4, the portable two-purpose gas cylinder that air pipe 12 is formed, motor 6 is speed-adjustable motors, it is fixed on the support 1 and by crank-connecting rod 4 and links to each other with the piston rod 21 of cylinder 7, air pipe 12 links to each other with cylinder 7, crank-connecting rod axle 3 flexibly connects with support 1, pedal-rod 9 flexibly connects with cylinder 7, one end head is a foot treadle 8, have flexibly connect with support 1 respectively on another termination at 2 of certain intervals, an end of carbine 14 links to each other with pedal-rod 9, the other end links to each other with support 1.

This portable two-purpose gas cylinder, air pipe 12 has barometer 11 and Adjustable pressure limiting valve 10 with cylinder 7 connecting places.

This portable two-purpose gas cylinder, the outer shell 17 of described cylinder 7 is overlapping inner casing 16, and vent 22 is arranged on the cylinder head 23, and suction valve 20 is arranged on the piston 15, and there is outlet valve 19 inner casing 16 ends, and outer shell 17 has outlet valve 18 with air pipe 12 connecting places.

The utility model is connected with cylinder piston by crank-connecting rod owing to be to set up motor on the basis of existing Pedal inflator, so but not only can be electric gas-filled, but also manual inflation, speed control switch is the may command aeration speed also; Cylinder is double-deck cylinder, and compact structure, gas storage chamber respective volume are bigger, can adapt to lower-powered motor, and be also very laborsaving during the manual inflation; Root a tree name application area is selected dissimilar speed-adjustable motors for use, goes for to various types of Tyre inflatings.Because simple in structure, thus cheap, and volume is small and exquisite, thus easy to carry, use also very convenient.

Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing embodiment, but structure of the present utility model is not limited to shown in the accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a plan view of the present utility model.

Fig. 3 is the sectional view of cylinder of the present utility model.

Fig. 4 is the structural representation of another mode of execution of the utility model.

Among Fig. 1, the portable two-purpose gas cylinder of forming by cylinder 7, motor 6, support 1, crank-connecting rod 4, air pipe 12, motor 6 is fixed on the support 1 and by crank-connecting rod 4 and links to each other with the piston rod 21 of cylinder 7, air pipe 12 links to each other with cylinder 7, its connecting place has barometer 11 and Adjustable pressure limiting valve 10, has speed control switch 5 to be used to regulate the rotating speed of motor 6 on the motor 6.Pedal-rod 9 is connected in 0 point with cylinder 7 by hinge axis, and cylinder 7 can freely be rotated; One termination of pedal-rod 9 is to have the hinge axis 0 of certain intervals and pin 13, pin 13 fixed pedestal bars 9 and support 1, another hinge axis 0 to be connected through the hinge with support 1 on foot treadle 8, another termination, and this point also can rotate.

Among Fig. 2,0 is the rotating hinge chain rivet, and crank-connecting rod axle 3 is connected by latch 2 at 0 place with support 1, only latch 2 need be extracted to get final product when not needing fixedly.One end hook of carbine 14 is lived pedal-rod 9, another termination is fixed on the support 1, because the effect of spring automatically resets after foot treadle 8 is depressed, inflator can also not depress pedal-rod 9 to hook to pack up with the hook on the support and make volume-diminished by the time spent.

Among Fig. 3, the outer shell 17 of cylinder 7 is overlapping inner casing 16, and plural vent 22 is arranged on the cylinder head 23, and more than one suction valve 20 is arranged on the piston 15, and there is at least one outlet valve 19 inner casing 16 ends, and outer shell 17 has an outlet valve 18 with air pipe 12 connecting places.

Among Fig. 4, the utility model also can adopt the fixing mode of cylinder, and it is fixing to be about to cylinder 7, piston rod 21 is connected with hinges 24, hinge 24 can be designed to universal connecing or axle sleeve type, increases a connecting rod 25 and is connected with existing axle sleeve, when motor 6 rotates piston 15 is moved reciprocatingly.Can make like this process of inflating steadily, wearing and tearing and resistance all can reduce, to improve mechanical efficiency.

During use, when with manually inflating, plug latch 2, remove pin 13, foot treadle 8 moves up and down and can inflate; During electronic inflating, plug pin 13, remove latch 2, it is promptly inflatable that speed control switch is connected with the mains, pressed to motor 6, controls the rotating speed of motor 6 with the diverse location that switch is pressed, thereby control aeration speed (noticing that the per minute reciprocating motion of the pistons is no more than 200 times); The time spent is not removed pin 13, plugs latch 2, and it is good that pedal-rod 9 is depressed hook, can put into case.

The different application area of root a tree name can be matched dissimilar speed-adjustable motor 6, is applied to the inflation of bicycle, motorcycle tire, when selecting for use 220 volts Ac that motor is powered, and the motor 6 optional distribution tool speed-adjustable motor of starting building, inflator adopts Pedal inflator design; Motor 6 also can adopt the speed governing electric drill; The electric drill link press span (can be designed to the knot that can be undone by a pull formula, easy disassembly) of packing into, it is electronic that inflation is realized, and take off and can use as electric drill, but not overlapping investment of one-object-many-purposes.When non-transformer, also available foot-operated, realization manual inflation, if Motor Vehicle adopts storage battery power supply, motor 6 selects the low-voltage direct motor, the cylinder dimensions of pump, power of motor and speed control switch are according to the needs design that is fit to the tire aerating.Can carry out safe inflation to all kinds of tires, rubber dinghy, balloon etc., weight generally only is the 3-10 kilogram.In its suitcase of packing into, be easy to carry.Because manufacturing process is simple, so cost of production is cheaper, the general cost valency is about 50-150 yuan, so this portable two-purpose gas cylinder has excellent popularization and using value.
