Description
Technical Field
The invention relates to an air nozzle joint for connecting an inflating nozzle of a vehicle tire, which is used for inflating the tire, in particular to a design aiming at high pressure and quick combination and simple separation of a French air nozzle.
Background
The inflation of vehicle tyre utilizes to install the charging connector of a check valve design on the tire, recycles the force (forcing) pump and aerifys it, and the force (forcing) pump end is equipped with a gas nozzle joint to this gas nozzle joint combines the charging connector and switches on, and all gas nozzle joints combine the charging connector at present, all need switch over the fixing device on the gas nozzle joint and open the back, just can combine the gas nozzle joint to the charging connector, locks this fixing device again, makes the firm interlock charging connector of gas nozzle joint, just can let the hand release at this moment aerify smoothly.
The fixing device mainly has the following three modes:
one is pulling and tightening the way, this kind of pulling and tightening the way is to utilize the rubber in the compression air cock joint to tighten the charging connector, use need not cooperate the screw tooth on the charging connector therefore very convenient, but the pure rubber tightens the power way poor, uses high pressure to aerify and can drop.
The other is a thread rotating mode, the thread rotating mode is that the rotation of a female thread in the air nozzle joint is utilized, the rotation of a male thread of the inflating nozzle enables the air nozzle joint to fix the air nozzle in a threaded manner, and although the air nozzle joint can be used for high-pressure inflation, the thread rotating process is very slow and inconvenient.
The other mode is a sleeve control sliding block mode, wherein the inner side of a sliding block is provided with male screw teeth, the teeth of the sliding block can be embedded and clamped with the inflation nozzle, the sleeve is grasped and pushed forwards to control the teeth of the sliding block to move to obtain embedding and clamping, and the separation also needs to be grasped and pulled backwards to control the teeth of the sliding block to move to separate from the male screw teeth.
Besides the above disadvantages, the three methods all have to be operated by both hands, and the air nozzle joint has to be operated by an operation fixing device before and after the air nozzle joint is combined with the inflating nozzle, so that the use is inconvenient, awkward and troublesome.
In order to overcome the above disadvantages, the inventor of the present invention has previously developed a patent of "Joint structure for an air valve" in U.S. Pat. No. 10,166,825 B2, which applies an air nozzle Joint to inflate an inflation nozzle in combination, the inflation nozzle is automatically inserted from the air outlet end channel, and the separation is performed by pressing the manual portion of the control member, so that the present invention has the advantages of simple and convenient operation, and the teeth engaging with the screw teeth of the inflation nozzle are more reliable and stable, and are more suitable for high pressure inflation.
