Description
Technical field
The utility model relates to a kind of inflator, relates in particular to a kind ofly when promoting and spurring its actuating strut, all can make air flow out inflating, and go into to finish the two-way pump that pulls of inner air filling with seasonal air stream.
Background technique
For inflatable object such as the inflations such as bicycle tire, basketball less to volume weight, develop gradually at present and air-inflating device miscellaneous, what wherein be widely used is a kind of air-inflating device of pedal, yet it is often because volume is big, weight is heavier, can't conveniently carry, the pump that pulls that a kind of volume is less, weight is also lighter so develop gradually again afterwards, can make things convenient for carrying of user.
See also shown in Figure 8ly, the pump that pulls of prior art generally has a body 40, an actuating strut 50 and a pneumatic tube 60, wherein;
This body 40 is to be a hollow tube, and its inside has air chamber 41 and closed at both ends, and wherein end central authorities have an air outlet of running through 42, and other end central authorities have a perforation 43;
This actuating strut 50 is to be the body of rod with two ends, its external diameter is slightly less than perforation 43 internal diameters, and the one end is penetrated within the body 40 by perforation 43, this end end is connected with an action disk 51, this action disk 51 can be subjected to actuating strut 50 push-and-pulls and in air chamber 41 axis move, and periphery is surrounded with driving fit part 510; The other end is positioned at outside the perforation 43, and its end place is connected with leader 52 and is available for users to grip.
This pneumatic tube 60 is with on the detachable outer wall that is installed in body 40, but its central authorities have the circulation of runner air feed stream, and an end has joint 61 and can be connected with air outlet 42, flows out but the other end has opening air feed stream, and this opening can be installed an air punch 62.
During use, the user grips handle 52 with hand, application of force pushing action bar 50, make action disk 51 within air chamber 41 toward 42 directions move relative to the air outlet, thereby the air in the body 40 are promoted and flow out toward air outlet 42 directions, flow out along pneumatic tube 60 also or after pneumatic tube 60 installings and reach inflation.And after this action disk 51 is pushed into air chamber 41 end places, then again actuating strut 50 is oppositely retracted, make action disk 51 in air chamber 41, move toward 43 directions of relatively boring a hole, make air flow in the air chamber 41 by the gap between actuating strut 50 and the perforation 43, refill action disk 51 to air chamber 41 spaces between 42 end faces of air outlet, wait for action again.
The prior art pull that though pump weight is light, volume is less, can be convenient for carrying and use, yet, it only can make gas flow out when pushing action bar 50, and also needs constantly to come the filling air by pulling action bar 50, has so wasted the stroke of action, increase operational program, not only have influence on the speed finished of inflation, and use to go up and need the more strength of cost, thereby reduce its utilization benefit; In addition, its pneumatic tube 60 is installed on body 40 outer walls, also can influence its overall appearance.
The model utility content
Technical problem underlying to be solved in the utility model is, overcome prior art and pull the above-mentioned shortcoming that exists when pump uses, and a kind of two-way pump that pulls is provided, it can effectively increase the speed of inflation, further pneumatic tube is hidden in body interior to increase overall appearance.
