Abstract
The utility model relates to a micro inflating pump which belongs to the product of the class of the daily using tool, comprising an air cylinder, a pull rod, a piston, a handle, etc. The utility model is characterized in that the diameter of the fixing part of the piston, the pull rod and a sealing ring is smaller than the diameter of the sealing ring, an inflating nozzle keeps a definite included angle with the air cylinder, and the object can be directly inflated in using. The utility model has convenient carrying, low cost, and artful design. The utility model is an ideal article for daily use.
Description
The utility model relates to a kind of minitype pump, belongs to daily instrument series products.
Pump is the very strong daily instrument of a kind of applicability, and for many years, people use iron pump, but use till today because of it does not have comparatively desirable pump.Several years ago, people attempt to substitute iron pump with the plastics inflator, influence working life because of its plunger designs is unreasonable with use plastic wear-resisting poor performance again, and are not used.
The purpose of this utility model provides a kind of simple in structure, and reliable performance is easy to carry, the minitype pump that applicability is strong.
The purpose of this utility model can reach by following measure.Design a kind of pump that comprises that inflator, pull bar, piston, handle etc. are formed, the inflator inner diameter guarantees consistent size, so that air pressure can effectively seal.The design of piston one-way cock has belonged to known technology, and the utility model is not set forth.Piston pulling rod seal ring bearing diameter is less than the seal ring inner diameter, guarantee certain clearance, monolateral gap is that 0.5-1mm is advisable, to prolong inflator working life, owing to connect by steel wire between the bicycle tyre valve, therefore, pump sealed mouth car inflator between centers should keep certain included angle, and this angle is comparatively moderate between 30 °-60 °.When bicycle is inflated, aim at the bicycle valve, promote piston pulling rod, can inflate bicycle with sealed mouth.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
Fig. 1 is the utility model structural representation
Among the figure
1. handle 2. pull bar retaining rings 3. inflators
4. seal ring retaining ring 5,6. sealing gasket 7. pull bars
8. seal ring 9. sealed mouths
The bicycle charging air inlet is designed to 45 in the present embodiment, owing to be provided with rubber washer in valve, therefore, even angle is inflated between 30 °-60 °, effect is also comparatively desirable.
The utility model is easy to carry, and cost is low, and deft design is reasonable, is the ideal life articles for use.
Claims (3)
1, a kind of minitype pump of being made up of inflator, pull bar, piston, handle etc. is characterised in that piston pulling rod seal ring bearing diameter is less than the seal ring inner diameter.
2,, be characterised in that the monolateral gap between seal ring bearing diameter and the seal ring inner diameter is 0.5-1mm according to the described minitype pump of claim 1.
3, be characterised in that according to the described minitype pump of claim 1 bicycle sealed mouth and the axial angle of inflator are 30 °-60 °.
