Abstract
The utility model relates to an inflator, its characteristics are two-way hand formula, and it includes that control rod 1, bottom plate 2, control rod 1 articulate on bottom plate 2, and it has piston rod 4 to articulate at control rod 1's middle part, is equipped with fixed guide 6 in the piston rod 4, and its external fastening has piston ring 7, and piston ring 7 can slide in gas cylinder body 8, is equipped with upper cover 9 on gas cylinder body 8's upper portion, and oil blanket 10, oil blanket lid 12, lower part are equipped with cover 13, are equipped with check valve 14 and controller 15 on the cover 13, the utility model adopts the above structure, inflation efficiency improves greatly.
Description
The utility model relates to a kind of pump.
The manual pump that people now use is push type, be that the operator vertically exerts oneself the operational pump tube to tyre inflation, this manual pump is unidirectional inflation, just inflates to bicycle when pressing down, be the piston idle stroke when upwards drawing, use this inflator to waste time and energy.
The purpose of this utility model is to provide a kind of shaking type bidirectional pump tube.
The purpose of this utility model is to realize like this, it comprises operating handle, base plate, operating handle is hinged on the base plate, is hinged with piston rod at the middle part of operating handle, and the other end that the fixed guide bar piston rod is housed in the piston rod is fastened with piston ring, piston ring can slide in inflator, oil sealing and the oil seal cover that has vent are housed on the top of air cylinder, and cover is equipped with in the bottom, and cover is provided with one-way valve and passage.
The utility model is simple in structure, and low cost of manufacture is time saving and energy saving, and efficient increases significantly than former pump.
Below in conjunction with accompanying drawing its structure is further described
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a right elevation of the present utility model
The utility model comprises operating handle (1), base plate (2), operating handle (1) is hinged on the base plate (2) by fulcrum (3), be hinged with piston rod (4) at the middle part of operating handle (1), piston rod (4) is a hollow stem, be drilled with pore (5) on it, fixed guide bar (6) is housed in piston rod (4), its the other end is fastened with piston ring (7), piston ring (7) can slide in air cylinder (8), loam cake (9) and oil sealing (10) are housed on the top of air cylinder (8), with the oil seal cover that has vent (11) (12), leave the gap between loam cake (9) and the piston rod (4), in the bottom of air cylinder (8) cover (13) is housed, cover (13) is provided with one-way valve (14) and controller (15), and an end of fixed guide bar (6) is fixed on the cover (13).Controller (15) relates to cover (13), is drilled with venting channels (18) and three circulation passage (16) on cover (13), and free ball (17) is housed in three circulation passage (16).
When the utility model used separately, base plate (2) was a supporting baseplate, and when the utility model and bicycle used with car, base plate (2) was a fixed support, can be fixed on the bicycle.
When using the utility model, promote operating handle (1), when making piston ring (7) near cover (13), one-way valve (14) is closed, air-flow makes steel ball block the center upper channel in the tube, air-flow charges into tire from three circulation passage (16) through the air outlet, vacuum is formed at inflator top in the inflation of inflator bottom, the gap of air-flow between loam cake (9) and piston rod (4), and vent (11) enters inflator top, when promoting operating handle (1), piston ring (7) is when the oil seal cover, and piston rod drives on the oil sealing (10) and moves the gap of blocking between lower cover (9) and the piston rod (4), and air-flow enters pore (5), flow to the air outlet through three circulation passage (16), to tyre inflation, steel ball is blocked the center lower channel under the effect of air-flow at this moment, the air cylinder bottom is owing to the effect of vacuum, and air-flow enters through one-way valve.
Claims (2)
1, a kind of pump, it is characterized in that it comprises operating handle (1), base plate (2), operating handle (1) is hinged on the base plate (2) by fulcrum (3), be hinged with piston rod (4) at the middle part of operating handle (1), piston rod (4) is a hollow stem, be drilled with pore (5) on it, fixed guide bar (6) is housed in piston rod (4), its the other end is fastened with piston ring (7), piston ring (7) can slide in air cylinder (8), loam cake (9) and oil sealing (10) is housed on the top of air cylinder (8) and has the oil seal cover (12) of vent (11), leave the gap between loam cake (9) and the piston rod (4), in the bottom of air cylinder (8) cover (13) is housed, cover (13) is provided with one-way valve (14) and controller (15), and an end of fixed guide bar (6) is fixed on the cover (13).
2, pump according to claim 1 is characterized in that controller (15) comprises cover (13), is drilled with venting channels (18) and three circulation passage (16) on cover (13), and free ball (17) is housed in three circulation passage (16).
