Wrenchless pump nozzle

Abstract

The invention discloses a wrench-free inflator air faucet. The wrench-free inflator air faucet consists of an air faucet head, an air faucet and a pressure injector, wherein the air faucet head is provided with a tapered hole which penetrates through the bottom end of the air faucet head in an aperture downward-diverging mode; the top end of the tapered hole is connected with a first hole; the first hole is further connected with a gas inlet path; the air faucet is composed of a first frame body and a second frame body; the first frame body and the second frame body are provided with faucet openings capable of being folded; the top edges of the first frame body and the second frame body are coupled by a first pivotal part and a second pivotal part, and are positioned at an original point in the tapered hole by a locating part; the pressure injector can be in gastight sliding fit along the first hole, is provided with an intermediate hole connected with the gas inlet path, pushed by an elastic assembly to resist against the top ends of the first frame body and the second frame body; the faucet opening is used for allowing a connecting faucet to insert from bottom to top in the downward-diverging mode; when the connecting faucet drives the first frame body and the second frame body to move upwards, the tapered hole can force the first frame body and the second frame body to tightly fold, thereby packing the faucet opening to clamp the connecting faucet and enabling the intermediate hole to connect with the connecting faucet for inflating; but when the connecting faucet is forced to drop out of the faucet opening, the connecting faucet can link the first frame body and the second frame body to return to the original point for being separated from each other.

Description

technical field [0001] The present invention relates to a wrenchless air pump nozzle, especially a special technology that can save time and labor and one-handed operation, and can greatly prolong the service life of the nozzle. Background technique [0002] Existing air pump air nozzle is just as shown in No. M318073 of China Taiwan Announcement, and its air nozzle head is in an assembly hole, and is provided with rubber air nozzle, clip seat, spring, pressure injector sequentially from bottom to top, and more There is a wrench with a cam pivoted above the injector. When inflating, people 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 injector to overcome The spring moves downward along the axial direction of the assembly hole with the preset elastic force, further suppressing the "axial elastic deformation" of the air nozzle, so that the air nozzle can "radially elastically defo...

AI Technical Summary

Problems solved by technology

[0004] 1. When people want to inflate and drive the wrench, in addition to overcoming the spring, the applied force must also act on the "axial elastic deformation" and "radial elastic deformation" of the tuyere, which is quite laborious and difficult to operate with one hand, and requires One hand holds the air nozzle head and the other hand drives the wrench, which is enough to cope with it. It is very inconvenient to use, especially when inflating the ball, you must clamp the ball through your feet to operate the pump. Mouth, often feel 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". Elasticity fatigue and loss of airtightness, causing people to have air leakage from time to time when inflating

[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.
