Description

Screw-in nozzle joint

The invention relates to a gas nozzle joint, in particular to a screw-in nozzle joint.

There are many types of tire nozzles, mainly French and American nozzles. The special nozzles are not able to universally connect the American nozzles and French nozzles. Therefore, the nozzles of the pump are not directly inserted into the tires. The air nozzle can be used. Firstly, whether the air nozzle on the tire is American or French, and then the suitable air nozzle joint corresponds to the air nozzle. Since the US air nozzle joint is more common than the French air nozzle joint, if the French style is desired, When the air nozzle is inflated, the French air nozzle joint must be converted in the American air nozzle joint to inflate. If the adapter is not carried, the French air nozzle cannot be inflated, and the nozzle joints are various in variety and the appearance is different. After the conversion of the nozzle joint, it may be interfered by the spoke of the tire, which is more detrimental to the inflation of the nozzle joint and the nozzle connection.

Therefore, a gas nozzle joint which can be applied to both the American air nozzle and the French air nozzle is developed. It is a "US-style gas nozzle universal joint" disclosed in the Republic of China Patent No. I571579, which is designed to be a wrench in the outer casing. And connected with the internal components, the nozzle joint is horizontal when the nozzle joint is not in use, and can be repeatedly pulled between a loose position and a fastening position, but the structure of the tire strip and the wheel frame is tightly combined The space of the nozzle of the nozzle of the air nozzle joint device is too narrow, and the wrench of the air nozzle inflation joint is easily blocked by the tire strip when the user installs, and the trigger lever is not easy to be loosened to the fastening position, and When the trigger is pressed, the front end of the nozzle joint is easily deformed. This design is prone to air leakage or looseness. The user needs additional operating space to pull the trigger lever, which greatly increases the difficulty of installation.

In view of the above-discussed shortcomings of the prior art, it is an object of the present invention to provide a screw-in air nozzle joint that achieves the effect of simple installation.

Accordingly, the present invention relates to a screw-in nozzle joint comprising a fixing tube, a spring element, a thimble, a limiting ring and a rotating ring.

The air inlet portion has an air inlet communicating with the receiving hole, and the driving portion is an outer ring surface on which the tube body is disposed.

The spring element is disposed in the receiving hole, and the spring element has a pressing end that abuts at one end of the air inlet and a force end that is opposite to the pressing end.

The ejector pin has a force receiving end at which a bottom end is inserted into the spring element, a thimble end opposite to the bottom end, a carding end between the bottom end and the ejector pin and abutting against the force receiving end, and a pin Through the thimble air passage of the bottom end and the ejector end, the spring element provides an elastic force to the locking end of the thimble to maintain the ejector pin with a pre-displacement force toward the venting portion, and the ejector air passage communicates with the accommodating hole.

The limiting ring is sleeved on the ejector pin and is abutted by the clamping end. The limiting ring has a first threaded hole for screwing the French air nozzle.

The rotating ring is pivotally disposed on the air outlet portion, and the rotating ring has a second threaded hole for screwing the American air nozzle.

The utility model has the advantages that the utility model is screwed into the American air nozzle or the French air nozzle on the tire, and in particular, the outer shape of the invention does not require an additional operation space, and is not operated by the tire on the tire. The spokes interfere with the ease of installation.
