Abstract
The utility model relates to a bicycle air pump which is characterized in that an air valve fixed on a cylinder body can be directly sheathed and pressed on a valve inside of a bicycle to inflate after the air valve is embedded with a sealing ring and is sheathed with a nut. In order to prevent the inner air leakage caused by the deflection of a push-pull rod, an inner core with smaller diameter than the cylinder body is sheathed on the push-pull rod. The utility model has the advantages of small volume and convenient carrying, and is favorable for a rider to inflate in time.
Description
The utility model relates to a kind of bicycle pump.
China is a bicycle big country, be the inflator of bicycle tyre inflation also shape form formula, general gas letter is arranged, gas cylinder is also arranged, and these inflator volumes are bigger, carry inconvenience, on its structure, all have the air door clip that a rubber pipe is connected with rubber pipe one end,, need inflation just very difficult in the way because inconvenience is carried.
The purpose of this utility model provide a kind of simple in structure, volume is little, the bicycle pump that is convenient for carrying.
The purpose of this utility model is achieved through the following technical solutions, a kind of bicycle pump that comprises the pull bar of stack shell, handle and an end fixed piston, the externally threaded valve of the peripheral idiozona of hole that it is characterized in that the closely low end side surface of stack shell, the embedded pressure seal ring of valve, overlap spin nut on the valve, be with inner core on the pull bar between handle and the piston, the diameter of inner core is slightly less than the inner diameter of stack shell.
The utility model is simple and light, directly the valve cover on the stack shell is pressed on the valve inside of bicycle during use, utilizes valve inside air inlet only, stops the principle of return-air, has saved the safety check that existing inflator must have.After being with inner core on the pull bar, prevented at the volley crooked of pull bar effectively and made gas leakage in the crooked generation of piston, the utility model has also saved air door clip and the rubber tube that existing inflator must have, slightly take some power than existing inflator when inflating, but because its volume is little, easy to carry, for inflation has in time brought convenience.The utility model can be placed in the traveling bag, also can have very strong practicability by the jig device on the slash of bicycle.
Accompanying drawing 1 is the utility model master TV structure schematic representation;
Accompanying drawing 2 is the utility model plan structure schematic representation;
Accompanying drawing 3 is the utility model stack shell internal structure schematic representation;
Accompanying drawing 4 is the utility model broken section structural representation.
In the accompanying drawing: the 1st, stack shell, the 2nd, handle, the 3rd, piston, the 4th, valve, the 5th, rubber ring, the 6th, nut, the 7th, pull bar, the 8th, inner core.
Further specify the utility model in conjunction with the accompanying drawings and embodiments, fixing valve 4 around the hole of the side, nearly bottom of stack shell 1, valve 4 embedded pressure rubber rings 5, overlap spin nut 6 on the valve 4 again, be with inner core 8 on the pull bar 7 between handle 2 and the piston 3, the diameter of inner core 8 is slightly less than the diameter of stack shell 1.
Claims (2)
1, a kind of bicycle pump that comprises the pull bar of stack shell, handle and an end fixed piston, the externally threaded valve of the peripheral idiozona of hole that it is characterized in that side, the nearly bottom of stack shell, the embedded pressure seal ring of valve overlaps spin nut on the valve, be with inner core on the pull bar between handle and the piston.
2, bicycle pump according to claim 1 is characterized in that the diameter of inner core is slightly less than the inner diameter of stack shell.
