Trigger pump air nozzle

Abstract

The invention relates to a trigger type inflator air faucet. The trigger type inflator air faucet is composed of an air nozzle head, an air nozzle, a pressure injection device and a trigger configuration; a handle part is connected out from the air nozzle head, a push-and-pull hole allowing the bottom end to penetrate is arranged on the air nozzle head, and a notch is arranged on the push-and-pull hole; a first hole coaxially communicated with the push-and-pull hole is arranged at the top end and is additionally communicated with an air inlet way; the air nozzle is provided with a nozzle hole capable of clamping a connecting nozzle, is positioned at the original position in the push-and-pull hole through a limiting piece, and has the upwards-moving margin; the pressure injection device can be in slide fit along the first hole and is pushed by an elastic assembly to abut against the air nozzle, so that when the connection nozzle is inserted into a nozzle hole to drive the air nozzle to upwards move, the push-and-pull hole can firmly clamp the connecting nozzle by forcedly tightening the nozzle hole, and the follow-up air inflation operation is accordingly carried out; and the trigger configuration is mainly characterized in that a brake piece is coupled to the air nozzle head, one end edge of the brake piece can be operated and controlled by fingers for holding the handle part, and therefore the other end edge of the brake piece is linked to control whether the air nozzle is positioned to the position where the connecting nozzle is clamped or not.

Description

technical field [0001] The invention relates to a trigger type air pump air nozzle which can be operated with one hand and can greatly prolong the service life of the air nozzle. Background technique [0002] Press, the air nozzle of the conventional air pump is as shown in China Taiwan Announcement No. M318073. The air nozzle head is in an assembly hole, and the rubber air nozzle, the clip seat, the elastic component, and the pressure injection are arranged sequentially from bottom to top. There is also a wrench with a cam pivoted above the injector. When inflating, we only need to insert the American / French nozzle into the air nozzle from bottom to top, and then drive the wrench so that the cam can force the pressure. The injector overcomes the default elastic force of the elastic component and moves downward along the axial direction of the assembly hole, so as to further suppress the "axial elastic deformation" of the air nozzle, so that the air nozzle can "radial elasti...

AI Technical Summary

Problems solved by technology

[0004] 1. When we want to inflate and drive the wrench, in addition to overcoming the elastic component, the applied force must also act on the "axial elastic deformation" and "radial elastic deformation" of the air nozzle, which is quite laborious and difficult to operate with one hand. One hand is required to hold the air nozzle head and the other hand to drive the wrench, which is very inconvenient to use, especially when inflating the ball, the ball must be clamped by both feet to operate the pump Angry mouth, often feeling in a hurry

[0005] 2. The rubber nozzle clamps the American / French nozzle by converting the vertical "axial elastic deformation" into the horizontal "radial elastic deformation". Loss of airtightness due to fatigue fatigue, causing air leakage from time to time when we inflate

[0006] In view of the shortcomings of the conventional air pump nozzle, which cannot be operated with one hand and cannot be used for long-term airtight clamping, the inventor has developed the present invention after continuous conception and research.
