Abstract
The utility model relates to a mini-inflator, which is exclusively designed for a bicycle to go out conveniently. When the utility model is used, a screw cap at the end of an air pipe is connected and fixed on the air intake of a bicycle tyre. The utility model is mainly composed of components, such as an inflator body, a plunger, a draw rod, an air outlet, the air pipe, etc.
Description
The utility model relates to a kind of micro pump, particularly a kind of bicycle micro pump.
Existing various inflator, because volume weight is big, going out by bike, it is very inconvenient to carry, especially travel by bike in remote mountain area, rural area,, then can't expect to arrive or return the destination in case meet tire gas leakage, and unbearably worried, next this product cost cost height, the pin person of expense psychological burden is heavier.Therefore, can not spread to huge numbers of families.
The purpose of this utility model is to provide a kind of volume little, in light weight, and cost is low, and it is easy to carry to go out, inflate satisfactory for result, and short bicycle micro pump of time.
This inflator is characterised in that: on the basis of existing product, under the situation of reduced volume weight reduction, especially to the rubber seal ring of piston, be improved to little and thick by original approaching greatly, and the seal ring outer edge is improved to flattened state by the turnup state, thereby can prolong the working life of rubber seal ring greatly.In addition, the feature of this inflator also is: the valve of micro pump has screw thread on 3., and connecting valve 3. has nut with the pneumatic tube two ends 1. of bicycle valve core, can load and unload at any time to be convenient to preserve and use.
The purpose of this utility model is to realize like this; With wall thickness is 0.1 centimetre, and long 17 centimetres, diameter is that 7. 1.4 centimetres seamless steel pipe does air cylinder; The two ends of cylindrical shell have respectively plug 10. with a cover of bringing pore into 8., screw thread that 8. cover is gone up and cylindrical shell screw thread 7. matches, the valve that 10. plug of barrel front end is welded with a band screw thread 3.; With diameter is that 6. 0.2 centimetre steel wire makees pull bar, and 9. the pull bar top has a handle, and the pull bar front end has on the piston concave surface 4. and is with rubber seal 5..When inflating, the pneumatic tube the other end that will have nut is connected on the bicycle valve core, and pushing drawing rod is made straight line motion up and down then, then gas can be squeezed in the tire.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof, and accompanying drawing is the overall picture sectional view according to the micro pump that the utility model proposes.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
1. this tracheae device comprises a pneumatic tube, nut 2. valve 3., piston 4., seal ring 5., pull bar 6., air cylinder 3. cover 8., handle 9., plug is 10..During use 9. handgrip is moved up and down as straight line, 1. 3. gas can be delivered in the tire with pneumatic tube by outlet nozzle, promptly finished the overall process of whole enforcement.
Claims (1)
- A kind of bicycle micro pump is characterized in that:1, the rubber seal ring on the piston is fixed on the concave surface on the piston, does rolling friction when seal ring is inflated,2, outlet nozzle connects a pneumatic tube, and tube head has one for the fixing nut of pneumatic tube and bicycle valve core,3, on the outlet nozzle of inflator the screw thread silk is arranged, help the dismounting keeping of pneumatic tube after making.
