Abstract
The utility model discloses an external inflation valve for an air-storage type inflator, comprising an air-storage cylinder, a pipe body, a draw rod and a leather bowl. The utility model is characterized in that a steel ball and a spring are arranged in an air-permeation hollow screw, and air-out pipe is sheathed on the hollow screw, and is tightly screwed to engage with a screw nut on the out of the hollow screw. The air can not leak. The utility model has the advantages that the labor is saved when the utility model is used to inflate the bicycle, the air input is sufficient, the leather bowl in the inflator is not easy to be damaged, the maintenance is convenient, etc.
Description
The utility model relates to a kind of air-stored pump, this gas charging valve is welded on the outside of air storage pump bottom.
Existing pump, a kind of is the air-stored pump, when inflating to bicycle tyre, the leather cup compress inlet air under the pull bar of tube body is pressed in the bicycle inner tube through gas tank.Though it is laborsaving that this pump uses, the air inlet difficulty appears sometimes, and pull bar is pressed several following not air inlets of beating, and leather cup very easily damages.
The purpose of this utility model is that proposition is a kind of from pump outside air inlet, has overcome the shortcoming of existing air-stored pump deficiency of air.
Task of the present utility model is finished like this, it comprises gas tank, body pull bar and leather cup, it is characterized in that: the outer supporting nut that has of the cored screw of air inlet, in the intrinsic emptying aperture of cored screw, be equipped with steel ball and spring, the hollow tubular of giving vent to anger is enclosed within to tighten on the cored screw with nut and coincide, and is connected with bend pipe on the air outlet hole on the hollow tubular and is connected with the bottom of air-stored pump.Hollow tubular air outlet hole and the welding of air-stored pump bottom outside, the internal thread in the hollow tubular cooperates with cored screw to be tightened, and gas enters in the hole of cored screw.
The utlity model has following effect: owing to outside pump, increased gas charging valve, laborsaving when inflating to bicycle, the air inflow abundance, and also the leather cup in the inflator is not fragile, easy to maintenance.
Fig. 1 is a structural representation of the present utility model.
Describe embodiment in detail in conjunction with above accompanying drawing, the cored screw 1 outer supporting nut 3 that has is equipped with steel ball 2 and spring 4 in the cored screw 1 intrinsic hollow hole, and 6 li of hollow tubulars are that internal thread is inserted in to tighten on the cored screw 1 with nut 2 and coincide, and cause air tight.Beat a hole in the bottom outside of air-stored pump, hole corresponding be welded of the bend pipe on the hollow tubular 75 with the inflator outside.During inflation, twitch the cylindrical shell pull bar, the pulling force drive hollow tubular 7 of pull bar and the steel ball 2 of 1 li of cored screw, at this moment gas enters in the hole of cored screw 1, enters in the cylindrical shell through hollow tubular 7 and air outlet hole 6 and bend pipe 5, presses the cylindrical shell pull bar then, gas is charged into the interior tyre cavity of bicycle, when no longer inflating, put down the cylindrical shell pull bar, the steel ball 2 that cored screw is 1 li is by spring 4 reinstatement that resets.
