Air-valve joint of air-inflating device

Abstract

A nozzle joint of an air charging device comprises a shell with an air inlet channel, a least a nozzle component inside the shell and connected with the air inlet channel, the nozzle component composed of a spring sleeve, a hold part with a bottom, extending two parallel arm from the bottom, the shell contained between two arms of the holding parts, whose bottom corresponding to each nozzle part having a through hole, a banner part setting between holder two arms through a pin, with two end surfaces with one of it having smaller distance to the pivot center than the other. When the first end surface contacts with the shell, spring component of the nozzle sleeve at loose ends, and when the second end surface contacts with the shell, bottom of the holder part attaches to the shell and spring sleeve of the squeeze nozzle component deformed. It is convenient assembly, solid action and labor saving.

Description

technical field [0001] The invention relates to an inflatable device, in particular to a structure of an air nozzle joint of the inflatable device. Background technique [0002] Such as figure 1 As shown, it is the previous case of the Taiwan No. 135498 patent (US 5,960,815). The conventional air pump nozzle connector includes a housing 10, a body 18 and two mouthpieces 14, 15 accommodated in the housing 10, and a The triggering member 27 is disposed on the housing with a pin 28 . What this patent discloses is a structure with double air nozzle joints, and the conventional single air nozzle joint structure only needs to omit one joint and the automatic switching valve therein. The known air nozzle joints must insert the mouthpieces 14, 15 into the bottom end of the housing 10, and then into the body 18. This structure makes the dimensional accuracy of the mouthpieces 14, 15 must be very high. The rubber mouthpieces 14, 15 The size of the 15 needs only to be slightly large...

AI Technical Summary

Problems solved by technology

The known air nozzle joints must insert the mouthpieces 14, 15 into the bottom end of the housing 10, and then into the body 18. This structure makes the dimensional accuracy of the mouthpieces 14, 15 must be very high. The rubber mouthpieces 14, 15 The size of the 15 needs only to be slightly larger, and it is prone to difficulties to tuck it into the bottom of the shell

Furthermore, when the puller 27 is pulled to cause relative displacement between the body 18 and the housing 10, it is necessary to overcome the friction between the body 18 and the upper anti-leakage ring 33 and the inner wall of the housing 10, which requires a relatively large force.
