Description

No wrench air pump nozzle

The invention relates to a wrenchless air pump nozzle, in particular to a special technique which can save time and labor, one-hand operation and greatly extend the service life of the air nozzle.

Press, the conventional air pump nozzle is as shown in China's announcement No. M318073, the wind mouth is tied in an assembly hole, and the rubber air nozzle, the clamp seat, the spring and the pressure injector are arranged in the order from bottom to top. Further, a wrench with a cam is pivoted above the injector. When inflating, we only need to insert the American/French nozzle from the bottom to the top, and then drive the wrench to make the cam force the injection. The device moves downward along the axial direction of the assembly hole against the preset spring force of the spring, and further suppresses the "axial elastic deformation" of the air nozzle, so that the air nozzle can "radially elastically deform" the airtightly clamped American/French nozzle. For subsequent inflation, after the inflation is completed, we must reverse the drive wrench to release the injector, so that the tuyere returns to its original shape to release the US/French nozzle.

However, the conventional configuration still has the following problems in practical use:

1. When we want to inflate and drive the wrench, its force must not only overcome the spring, but also the "axial elastic deformation" and "radial elastic deformation" of the air nozzle. It is quite laborious and difficult to operate with one hand. One hand holds the wind mouth and the other hand drives the wrench, which is enough for the inconvenience. Especially when the ball is inflated, the ball must be clamped through the feet to operate the pump. Mouth, there will always be a sense of rush.

Second, the rubber tuyere is converted into water by the vertical "axial elastic deformation" Flat "radial elastic deformation" to hold the American/French nozzle, the wind nozzle itself is subjected to great stress, and it is easy to be elastic and fatigue and lose airtightness, causing us to leak when occasionally inflating. problem.

The inventors of the present invention have developed the present invention by continually conceiving and innovating in view of the disadvantages of conventional air pump nozzles which cannot be operated by one hand and which cannot be used for long-term airtight clamping.

The invention provides a wrenchless pump nozzle, which comprises at least a tuyeres having a push-out hole whose aperture is gradually diverged and penetrates the bottom end, and the top end of the push-out hole is connected with the first hole. The first hole is further connected to an air inlet; the air nozzle is composed of the first and second frames, the first and second frames have a matching mouth, the top edge and the first pivot and the first The two pivots are coupled and positioned at an origin position in the push-out hole through the limiting member; and a injector that is airtightly slidable along the first hole and has an air inlet that is connected The intermediate hole is pushed by an elastic member to abut the top ends of the first and second frames, and the mouth opening can be opened downwardly to provide a nozzle to be inserted from the bottom to the top, and the first and second frames are driven on the mouthpiece. When moving, the push-pull hole can force the first and second frames to be tightly engaged, so as to force the mouth to clamp the mouth, so that the intermediate hole can be connected to the mouthpiece to inflate, but in the forced mouth to take off the mouth In the case of the hole, the nozzle can interlock the first and second frames to the original point, and the nozzle can be separated after the mouth hole is automatically opened.

Therefore, when the invention is intended to be separated from the American/French mouth, it can be used only by one hand to drive the wind mouth, and anyone can easily do it; in addition, the air nozzle is mainly applied by pushing holes. The horizontal force and the tightness of the American/French mouthpiece can greatly reduce the requirements of the wind nozzle for elastic deformation, thereby effectively extending the service life of the wind nozzle.

Please cooperate with the fifth, sixth and seventh diagrams. Since the mouth 23 is positioned at the origin position with the downward opening, the present invention intends to provide the French nozzle FV when the French nozzle FV is inflated. Inserting the nozzle hole 23 downward and upward, the French nozzle FV temporarily catches against the top edge of the nozzle hole 23, and the first frame body 21 and the second frame body 22 are moved upwards against the elastic force of the elastic member 50, so that the push hole can be pushed up. 12 forcing the first frame body 21 and the second frame body 22 to closely engage the first pivot portion 241 and the second pivot portion 242 as a fulcrum for clamping the French nozzle FV into the nozzle hole 23 and pressing The intermediate hole 45 of the injector 40 is connected to the French nozzle FV for subsequent inflation. At the same time, the limiting member 30 is correspondingly engaged with the third positioning portion 26, so that the air nozzle head 10 can be released. The French nozzle FV is inflated. After the inflation is completed, the person can force the French nozzle FV to pull out the nozzle hole 23, so that the French nozzle F V can interlock the first frame body 21 and the second frame body 22, and the limiting member 30 can be pulled out of the third positioning portion 26 for resetting to the origin. After the nozzle hole 23 is automatically opened, the French connector can be separated. Mouth FV.

Therefore, the present invention has at least the following features:

1. The invention only needs to hold the handle 11 with one hand, that is, the wind mouth head 10 can be driven away, and the legal mouthpiece FV can be used for subsequent inflation, which can be easily performed by anyone, especially when inflating the ball. It is only necessary to operate the hand with one hand and position the ball with another hand, without using the feet, so it is far more convenient in operation than the traditional one.

2. The present invention presses the French nozzle FV by the horizontal component force applied to the tuyeres 20 by the push-out hole 12, so that the requirements of the air nozzle 20 for elastic deformation can be greatly reduced, thereby effectively extending the use of the tuyeres 20 life.
