Abstract
The utility model relates to a miniature high-pressure air pump which belongs to the technical field of the air pump, comprising a barrel body, a barrel cover, a draw rod, a handle, an air nozzle and an air delivery pipe. The air nozzle is positioned on the side of the barrel body approaching to the bottom. The upper end of the draw rod is provided with the handle, and the lower end of the draw rod is connected with a piston whose middle part is a trapezoidal ring groove. An air inlet port is arranged in the trapezoidal ring groove, and a seal ring is sheathed in the trapezoidal ring groove. The utility model has the advantages of simple structure, small volume, light weight, and convenient carrying. The length of the barrel body of the air pump is 23.3 cm, and the weight of the air pump is 160 grams. The high pressure can be generated in using, the labor and the time are saved, and the inflating speed is past.
Description
The utility model belongs to the inflator technical field, is a kind of high-pressure mini inflator.
China has the maximum country of bicycle, and bicycle spreads all over town and country, enters every household, becomes the traffic tool that people generally use, but at present popular bicycle pump is mostly relatively heavier, and inconvenience is carried, and is not durable.Though once occurred a kind of minitype pump in the past, because the outlet nozzle of this inflator is on the bottom of cylindrical shell, when inflating, must inflator by a hand end, another hands movement pull bar is inflated, can not get the support on ground because of cylindrical shell, energetically bad making, it is leather cup that the parts of calming the anger in addition adopt, gas leakage easily, damage, therefore use difficultly time-consumingly, this product is disappearing soon on the market.
The purpose of this utility model is to provide a kind of simple in structure, and is light and handy, volume is little, be convenient to carry, use laborsaving saving time, and has the high-pressure mini inflator of high-voltage performance
The purpose of this utility model realizes with the following methods.This high-pressure mini inflator comprises cylindrical shell, cover, pull bar, handle, valve, pneumatic tube, valve is positioned near the side, bottom of cylindrical shell, and the upper end of pull bar is handle, the affixed piston in lower end, and middle of piston is trapezoidal annular groove, in the trapezoidal annular groove inlet hole is arranged, seal ring set is arranged in trapezoidal annular groove.Below in conjunction with embodiment's accompanying drawing the utility model is described in further detail.
Fig. 1 the utility model structural representation
Among the figure: the trapezoidal annular groove of 1-handle 2-pull bar 3-cover 4-cylindrical shell 5-piston 6-seal ring 7-inlet hole 8-pressure cap 9-pneumatic tube 10-positioning convex ring 11-sealing gasket 12-valve 13-valve inside connecting head 14-
Seal ring (6) adopts abrasive rubber, and the inwall of cylindrical shell (4) is close in the outside of ring, and seal ring (6) can move up and down in trapezoidal annular groove (14).Inlet hole (7) is two.Pneumatic tube (9) is gone up and there is positioning convex ring (10) joint of valve (12) and is with sealing gasket (11), pressure cap (8) one end covers are stuck in positioning convex ring (10) and locate, the other end is threaded with valve (12), the terminal valve inside connecting head (13) of pneumatic tube (9) also is to be made of positioning convex ring, sealing gasket, pressure cap, during use, pressure cap is threaded to screw with the valve inside of bicycle to get final product.
The utility model in use, earlier valve inside connecting head (13) is connected with the valve inside of bicycle, the cylindrical shell bottom of inflator is supportted on the ground, buttress cylindrical shell (4) on the other hand, another holds handle (1) and handle is pulled outwardly, by pull bar (2) piston (5) is moved upward like this, at this moment the seal ring (6) in trapezoidal annular groove (14) lining of piston (5) is in the bottom of trapezoidal annular groove, make progress with piston (5), piston bottom cylinder lumen forms vacuum, the space that air is located by cover (3) and pull bar (2) enters cylindrical shell (4) inner chamber, pass the top edge of piston (5) and the gap between the cylindrical shell (4) again and enter trapezoidal annular groove (14), enter the cylinder lumen of piston (5) bottom then by inlet hole (7), after piston (5) is raised to the top, again to pressing down handle (1), then piston (5) moves downward, at this moment, seal ring (6) is close to piston (5) top edge, sealed the gap between piston (5) top edge and cylindrical shell (4) inwall, air is compressed like this, air pressure raises rapidly, by pneumatic tube (9) and the inflation of valve wick feed bicycle tyre.Because the mating reaction of piston and seal ring, good sealing effect is difficult for gas leakage, again because valve (12) is positioned at the cylindrical shell side, and cylindrical shell can be supported on ground, inflates and is easy to strength, and the speed of inflating is fast, thus in cylindrical shell very fast formation high pressure, aeration speed is fast.
The utility model is simple in structure, volume is little, in light weight, in the above-described embodiments, 23.3 centimetres of the cylindrical shell length of inflator, weigh 160 the gram, be convenient to carry.It is time saving and energy saving to produce high pressure during use, only needs 30-50 second for a bicycle tyre inflation, and aeration speed is fast.
The utility model belongs to the inflator technical field, is a kind of high-pressure mini inflator.This inflator comprises cylindrical shell, cover, pull bar, handle, valve, pneumatic tube, valve is positioned near the side, bottom of cylindrical shell, and the upper end of pull bar is handle, the affixed piston in lower end, and middle of piston is trapezoidal annular groove, in the trapezoidal annular groove inlet hole is arranged, seal ring set is arranged in trapezoidal annular groove.The utility model is simple in structure, volume is little, in light weight, 23.3 centimetres of air cylinder body length, weigh 160 the gram, be convenient to carry, it is time saving and energy saving to produce high pressure during use, aeration speed is fast.
