Abstract
The utility model relates to an inflator which is characterized in that the utility model is in the bidirectional hand-operated type. The utility model comprises an operating rod 1 and a base plate 2. The operating rod is hinged on the base plate 2. A piston rod 4 is hinge on the middle part of the operating rod 1, and a fixing guide rod 6 is arranged in the piston rod 4. A piston ring 7 is fastened on the outside of the guide rod 6, and is slid in an air cylinder body 8. An upper cover 9, an oil seal 10 and an oil seal cover 12 are arranged on the upper part of the air cylinder body 8, and a cylinder cover 13 is arranged on the lower part of the air cylinder body 8. A one-way valve 14 and a controller 15 are arranged on the cylinder cover 13. The inflating efficiency is raised by adopting the structure.
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).
