Abstract

The utility model relates to a manual inflator which makes use of the structure of double cylinders. A shell body is divided into a large cylinder, a small cylinder and an air storage chamber; the large cylinder, the small cylinder and the air storage chamber are communicated by one-way valves; a large and a small plungers in the large and the small cylinders are connected with a large and a small connecting rods; the connecting rods are connected with a crank shaft supported in the shell body; a crank handle is fixed to the crank shaft. The alternative lifting and reciprocating movement of the large and the small plungers can be realized through the crank handle; compressed air in the air storage chamber can be connected with an air nozzle of a vehicle tyre through an air outlet nozzle to achieve the inflating task; an air pressure indicating mechanism can inform that the pressure in the tyre already reaches to a set value. The inflator can not be limited by the sitting and standing conditions of users; the utility model has the advantages of labor saving and convenience, and the utility model is particularly suitable for patients with disability and high blood pressure and old weaklings.

Description

Manual type inflating pump

The utility model relates to the vehicle inflator.

The inflator of vehicle inflator, particularly bicycle, always usefulness is pump, pedal hand-pulled very hard, particularly for permanent disability, hypertensive patient and old work unable to do what one wishes especially.

Task of the present utility model is to provide a kind of not only laborsaving but also is applicable to the shaking type inflator that wounded or disabled patient and old person use easily.

The utility model is achieved in that housing is separated into big cylinder, little cylinder, three chambers of air-storage chamber, each chamber is linked up mutually by one-way valve, one outlet nozzle is arranged on the housing, can connect the bicycle valve by flexible pipe, large and small piston is arranged in the large and small cylinder, flexibly connect with large and small connecting rod separately, the alternately lifting to-and-fro motion of large and small piston drives to be bearing in the bent axle on the housing two side and to drive large and small connecting rod by shaking the hand and reaches, when tire pressure reaches enough big, show by the tutorial light of air pressure indicating device.

This shaking type inflator utilizes double-cylinder structure, makes big small piston do alternately inflation action, people can stand and operate the operation that also can be seated, use laborsaving convenience, exempt the fatigue of bending over of old-fashioned pump, be specially adapted to permanent disability, hypertensive patient and old person and use.

Description of drawings.

Fig. 1 provides structural representation of the present utility model.

Fig. 2 is the F place partial enlarged drawing of Fig. 1.

Make following detailed description with reference to the accompanying drawings.

The embodiment of shaking type inflator (seeing Fig. 1-2): housing (1) is separated into big cylinder (11), little cylinder (6), (8) three chambers of air-storage chamber, three chambers all have one-way valve (9) to communicate with each other, greatly, little cylinder (11), (6) big in, piston (10), (5) with bearing pin respectively with greatly, small rod (12), (3) flexibly connect, greatly, small rod (12), (3) again with the mutually fastening flexible connection of obvolvent screw of bent axle (2), the two supports of bent axle (2) is on the axle sleeve of housing (1) two side endoporus, shake the hand (4) fixedly connected with bent axle (2), the outlet nozzle (7) on the housing (1) can link to each other with the bicycle valve by flexible pipe.In order to improve wear resistance, scribble wear-resistant paint at large and small cylinder (11), (6) inwall.

Air-storage chamber is provided with the air pressure indicating device in (8), it is made up of push rod (15), spring (14), tutorial light (13), air-storage chamber (8) upper end is separated out a battery case, battery is housed in the box and forms a circuit by push rod (15) and tutorial light (13).

When shaking the hand (4) when shaking, power is done lifting to-and-fro motion alternate with each other through large and small piston (10), (5) that bent axle (2) drives on large and small connecting rod (12), (3), pressurized gas in the large and small cylinder (11), (6) is opened one-way valve (9) and is entered air-storage chamber (8) and charged in the bicycle tyre, when the tire internal pressure reaches certain setting value, push rod (15) pressure spring (14) is connected circuit with tutorial light (13), the bright explanation pressure of tutorial light (13) has arrived setting value, should this is only hand.Air-storage chamber (8) pressure reduces, and spring (14) resets push rod (15), and circuit disconnects, by can satisfy the requirement of different pressures to the adjustment of spring (14).

Claims

1, a kind of shaking type inflator, comprise housing (1), piston, connecting rod, one-way valve (9), outlet nozzle (7), it is characterized in that this housing (1) is divided into big cylinder (11), little cylinder (6), (8) three chambers of air-storage chamber, link up mutually by one-way valve (9) each other, shake the hand (4) be connected with bent axle (2) on being bearing in housing (1) two side, bent axle (2) flexibly connects with large and small connecting rod (12), (3), does alternately lifting to-and-fro motion with large and small piston (10), (5) that large and small connecting rod flexibly connects in large and small cylinder (11), (6).

2, shaking type inflator as claimed in claim 1 is characterized in that being provided with in the air-storage chamber (8) battery powered air pressure indicating device, is made up of push rod (15), spring (14), tutorial light (13).

3, shaking type inflator as claimed in claim 1 or 2 is characterized in that large and small cylinder (11), (6) inwall scribble wear-resistant paint.
