CN2139181Y - Dual-purpose efficient inflator for lighting and inflating - Google Patents

Abstract

The utility model relates to an inflating device with functions of illumination and inflation. The device is composed of a handle provided with a light bulb, a piston-rod arranged inside with a power source, and, an air cylinder. The handle is provided with a switch, and the piston-rod is arranged inside with a spring slice. The handle is tightly screwed in with the piston-rod to form an illuminating circuit. When the handle is moved up and down, the piston reciprocating inside the air cylinder, the inflation can be carried out. The utility model has the advantages of compact structure, convenient portability and multiple functions; artfully combining the pocket inflator with the illumination function, with the most atmospheric pressure which can reach the gauge pressure of 588 kpa (6 kgf per square cm), the high-efficiency inflating device is suitable for bicycles, balls and toys.

Description

Dual-purpose efficient inflator for lighting and inflating

The utility model relates to and a kind ofly have illumination and inflate the efficient air-inflating device of two functions.

Pump on the present market, volume is big, and function singleness is carried inconvenience.Illumination torch kind is various, but does not have aerification function.Chinese patent application numbers 85203624.8 once had introduction, but did not have illuminating effect bicycle locking-type, pen type, spanner inflator.Chinese patent application numbers 91202227.2 was also once reported with the efficient pen type pump of model utility, but did not also have the function of illumination.

The purpose of this utility model is will provide a kind of can throw light on, and the two function high-efficient inflators that can inflate again have illumination by bike at night, and tire gas leakage is inflatable, realizes illumination and inflates the device of two functions.

The purpose of this utility model is achieved in that high-efficient inflator is made up of handle, piston rod, piston, cylinder and outlet nozzle.In the pump handle small electric bulb is housed, piston rod is a hollow stem, in power supply is housed, when handle was spun on the piston rod, the metal spring leaf that is installed in switch on the handle and the piston rod had been formed lighting circuit, can be used as illumination and using.Upper and lower when mobile when handle, the limited ring of cylinder upper end can make piston spacing, and piston is reciprocating in cylinder, can inflate.

This device will throw light on and high-efficient inflator combination cleverly, and structure is novel, though volume is little, will really have illumination and will inflate two functions, and it is 6kgf/cm that maximum gas pressure can reach gauge pressure 588KPa( ²Gauge pressure) can pump enough air in three minutes the empty tire of common 28 inches bicycles.To the article that ball, various toy and is highly necessary inflated, all applicable.

Structure of the present utility model is provided by following embodiment and accompanying drawing.

Accompanying drawing is illumination and inflation double-purpose efficient pump longitudinal sectional drawing.

Below in conjunction with accompanying drawing, describe concrete structure of the present utility model and working condition in detail.Handle (1) is a hollow-core construction, in have small electric bulb (15) to screw in it, and contact with still (14).Handle (1) can be by spinning down on the piston rod (3).Power supply (2) and metal spring leaf (5) are housed in the hollow cavity of piston rod (3), and metal spring leaf (5) can pick out the negative pole of power supply (2).Handle (1) and piston rod (3) screw, and fuse, and at this moment metal spring leaf (5) contacts with the fixed plate (10) of handle (1), and the positive pole of power supply (2) contacts with small electric bulb (15), has constituted lighting circuit.Circuit can be connected and cut off to switch (11) on the handle (1).Around the small electric bulb (15) optical reflection parabola (16) arranged preferably, the exterior edge face of handle (1) can optically focused convex lens (12) to be housed for well.Between handle (1) and the cylinder (4), have beveled mouth (9) to tighten up, this just becomes illumination torch easy to use.

Upper end restraining position ring block (17) at cylinder (4), there is outlet nozzle (7) cylinder (4) lower end, be with seal ring (6) on the piston (8), when handle (1) upper and lower when mobile, piston (8) is reciprocating in cylinder (4) thereupon, and its reciprocating stroke is between limited ring (17) and outlet nozzle (7).The pressurized gas that produce in the cylinder (4) are gone out by outlet nozzle (7), can inflate to object.

The power supply of this device can be a various ways, can make the pump of different sizes, model by No. 1, No. 2, No. 5 dryelement cell commonly used, changes battery, and is very convenient.Also can use small battery.

The utility model will throw light on and pocket pump combines effectively, make full use of the space, compact structure, and economical with materials, easy to carry.

Claims (3)

1, illumination and inflation double-purpose efficient pump are made up of handle (1), piston rod (3), piston (8), cylinder (4) and outlet nozzle (7), it is characterized in that in this pump handle (1) small electric bulb (15) being housed, and piston rod (3) is interior by power supply (2) is housed.

2, illumination according to claim 1 and inflation double-purpose efficient pump is characterized in that switch (11) is arranged on the handle (1), and metal spring leaf (5) is arranged in the piston rod (3).

3, illumination according to claim 1 and inflation double-purpose efficient pump is characterized in that handle (1) can be screwed off by piston rod (3).
