Abstract
The utility model relates to a pocket high-pressure air inflator which is a tool for inflating the tyre, the ball and the toy. An inflating nozzle and a cylinder body are in screw connection and are dismountable. A piston rod is hollow, and the inflating nozzle can be placed in the hollow part when the utility model is not used. An annular notch is arranged on the end of the piston rod, and a rubber sealing ring is placed on the middle of the piston rod. The inflating nozzle is composed of a high pressure rubber hose and an inflating valve with screw thread. The structure has the advantages of small volume, light weight, high inflation pressure, time saving and labor saving in using, simple structure, easy fabrication, low cost, and long service life.
Description
The utility model relates to a kind of instrument of giving tire, ball, toy inflation.
Bicycle, tricycle have been China individual's the main traffic tool at present, but must often inflate tire, particularly bicycle gas leakage or air pressure deficiency, just inflation immediately temporarily suddenly.To the common pump of present use, be stranded for volume is bigger, exist and carry inconvenience, awkward shortcoming particularly lives in the worker of high-rise building, and working must be to Tyre inflating if find, need under the upstairs house repeatedly to come and go to pick and place inflator, delayed valuable time.Be traveling in the vehicle on the backroad, might all can not find the place of inflation in tens lis, gas leakage will cause great trouble to the cyclist.
It is little that the purpose of this utility model just provides a kind of volume, gas cylinder easy to carry.
The utility model is by cylindrical shell, and piston rod, inflation are chewed three parts and formed.Inflation is chewed with cylindrical shell and is connected with the pressure-resistant rubber circle by screw thread, piston rod is to be made by plastic round tube, so be empty in the piston rod, when inflator is not inflated, inflation can be chewed from cylindrical shell and unload, it is placed in the piston rod, the space size of piston rod can be put down inflation and chew, when needing inflation, inflation chewed in piston rod take out, being contained in the cylindrical shell head can use.
It is pressure rubber tubing that the middle part is chewed in inflation, and an end is copper valve nozzle, and the band female thread is connected with the tire valve inside by this screw thread, can reach safe and reliable connection like this.The other end is the male joint that the ABS engineering plastics are done, and is connected with cylindrical shell by it, can connect corresponding valve nozzle to different inflation objects.
Cylindrical shell is made by the mold pressing of ABS engineering plastics, and an end is smooth mouthful, the other end perforate, and tapping embeds rubber washer and female connection part, chews with inflation to be connected when inflation herein.Piston rod inserts in the cylindrical shell by smooth mouthful of end.
Piston rod is the cylindrical body of being made by the mold pressing of ABS engineering plastics, and hollow is opened an annular groove in the end of piston rod along circumference, rubber seal ring of cover in groove, and its size just in time closely cooperates with cylinder inboard wall, works to drive gas when inflation.There is screw thread the other end end, lid by this piston rod that is threaded, just inflate handle, when inflation, hold this inflation handle, drive piston rod, calm the anger inward, after the end of band rubber seal ring reaches cylindrical shell bottom, again with its extraction, turnover motion and so forth, gas is chewed by inflation and is constantly entered in the tire, reaches the purpose of inflation.
Embodiment of the present utility model as shown in drawings.
Accompanying drawing is the structural representation of pocket gas cylinder.
1 is piston rod in the accompanying drawings, and 2 is cylindrical shell, and 3 is that inflation is chewed, and 4 is the copper valve nozzle of inner chamber band female thread, and 5 is pressure rubber tubing, and 6 is that connecting bolt is chewed in inflation, and 7 is the pressure-resistant rubber packing ring, and 8 is rubber seal ring, and 9 for inflating handle.
The actual use of the utility model shows to have following characteristics:
1) it is little to require to be made into volume according to different inflations, and lightweight inflator pump is therefore easy to carry.
2) inflation pressure height, speed is fast, and bicycle tyre only needs about 1 minute from no gas to abundance, laborsaving saving time during use.
3) simple in structure, easily manufactured, cost is low, and long service life is suitable for the inflation of tire, ball, toy etc.
Claims (4)
1, pocket gas cylinder is chewed by inflation, cylindrical shell, and piston rod is formed, and it is characterized in that it is with being threaded that inflation is chewed with cylindrical shell.
2, pocket gas cylinder according to claim 1 is characterized in that piston rod is a hollow, and the big I in its space is put down inflation and chewed.
3, pocket gas cylinder according to claim 1 is characterized in that the piston rod end has in an annular recess, the groove to place rubber seal ring.
4, pocket gas cylinder according to claim 1, it is characterized in that the inflation chew the middle part make by high pressure resistant rubber hose, inner chamber band female thread is chewed in the inflation of end.
