Abstract

A push-bar-free air pump nozzle comprises a nozzle head, an air nozzle, and a pressing injector. The nozzle head comprises a taper hole, of which diameter is divergent downward and penetrates through the bottom. A top end of the taper hole is in communication with a first hole and the first hole is in communication with to an air inlet. The air nozzle is formed of a first casing and a second casing. The first casing and the second casing define a mated nozzle hole and have a top that is coupled to a first pivot section and a second pivot section and is positioned at an original position inside the taper hole by means of a constraint element. The pressing injector is slidable along the first hole in air tight engagement therewith and comprises an intermediate hole in communication with the air inlet and is pushed by an elastic component against the top of the first and second casing. The nozzle hole is set in a downward divergent form to receive a connector to insert upward. When connector drives the first casing and the second casing to move upward, the taper hole forces the first casing and the second casing to tightly mate each other so as to force the nozzle hole to securely clamp the connector. The intermediate hole can now make contact with the nozzle hole and air inflation is performed. however, the connector links up with the first casing and the second casing to restore to its original point and separate from each other while forced retrieval from nozzle hole.

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 nozzle is tied into an assembly hole, and the rubber wind 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 to clamp the American/French joint by converting the vertical "axial elastic deformation" into a horizontal "radial elastic deformation". The wind nozzle itself is subjected to great stress and is extremely elastic and fatigued. The loss of air tightness causes us to have a problem of air leakage from time to time when inflating.
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 at least comprises:
a wind mouth having a push-out hole whose aperture is gradually diverging and penetrating through the bottom end, and the top end of the push-out hole is connected to the first hole, and the first hole is further connected with an air inlet;
a tuyere consisting of a first and a second frame, the first and second frames having a matching mouth, the top edge being coupled by the first pivot portion and the second pivot portion, and passing through the limiting member Positioned at the origin of the push hole; and a presser that can be hermetically slid along the first hole and has an intermediate hole that is connected to the intake port and is pushed by an elastic member to abut At the top of the first and second frames, the mouth of the mouth can be opened downwards, and the mouthpiece is inserted from the bottom to the top. When the mouthpiece moves the first and second frames upward, the push hole can force the first and The two frames are tightly engaged to force the mouth to clamp the mouth, so that the intermediate hole can be connected to the mouth and inflated, but the mouth can be linked first and second when the mouth is forced to come out of the mouth The frame is reset to the origin, and the nozzle can be separated after the nozzle 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.

Confidentiality.
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 mouthpiece FV is inflated. After the inflation is completed, the person can force the French mouthpiece FV to relatively close the mouth hole 23, so that the French mouthpiece FV can interlock the first frame body 21 and the second frame body 22 to make the limit position. Piece 30 out of the first The positioning unit 26, to reset to the origin, until distraction automatic nozzle hole 23, can be isolated in this French mouthpiece 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.
