Inflating device with threaded inflating head

Abstract

An inflating device with a threaded inflating head can be connected with an air nozzle and further comprises an air supplying mechanism and the inflating head. The gas supplying mechanism has an air outlet which can output gas. The inflating head comprises a threaded control seat, a fixing mechanism which sleeves the threaded control seat on the air supplying mechanism in a manner of being rotatable around a first axis, and an inflating joint. The inflating joint has a connecting valve which is mounted on the fixing mechanism in a manner of being rotatable along a second axis. The connecting valve has a threaded end for threaded connection with the air nozzle, a connecting hole which is connected with an air outlet, and a second driving part which engages the first driving part of the threaded control seat. Through cooperation of the components, the air nozzle can be mounted while simple operation and high convenience are realized.

Description

technical field [0001] The invention relates to an inflating device, in particular to an inflating device with a screw-rotating inflatable head which is detachably combined with an air nozzle by screw-rotating operation. Background technique [0002] refer to figure 1 , is a kind of existing pumping device 1, and this pumping device 1 can be connected with an air nozzle 11, and comprises a gas supply mechanism 12, and an inflation head 10 combined with this gas supply mechanism 12, and this gas supply mechanism 12 There is an inner cylinder 121 that defines a chamber 120, an outer cylinder 122 that can move back and forth along an axis relative to the inner cylinder 121, and a cylinder mounted in the chamber 120 of the inner cylinder 121. A gas storage bottle 124, the gas storage bottle 124 stores gas inside, and has a bottle mouth portion 125 that can be pierced. [0003] The filling head 10 includes a base 13 axially combined with the inner cylinder 121, the base 13 has ...

AI Technical Summary

Problems solved by technology

[0005] Although the existing pumping device 1 can achieve the purpose of being connected to or separated from the air nozzle 11 by rotating the tightening nut 18, the use occasions of the existing pumping device 1 are usually very close to the object to be filled, so as to aim at tire inflation. For example, the inflating head 10 must be inserted on the air nozzle 11 of the tire. Since there will be steel bars or rim covers and the like around the air nozzle 11 of the tire, the forced The volume of the tightening nut 18 should not be too large. When the tightening nut 18 is to be rotated after insertion, it will not only be difficult to apply force, but also hinder the hand, and it is quite inconvenient to operate.

In addition, it is quite laborious to rotate the tight nut 18 with a small volume to press the push ring 17 to force the clamp ring 16 to deform.

When the tightening force of the tightening nut 18 is not enough, it is easy to cause air leakage and inaccurate inflation.
