Description

Horizontally turned inflation joint

The present invention relates to an inflation joint, and more particularly to a horizontally-turned inflation joint.

Pressing, an inflator (such as an inflator, an air pump, etc.) and a nozzle of the tire must be connected by an inflation joint so that the gas of the inflator can be injected into the tire by the inflation joint. In the mouth of the gas, the effect of inflating the tire is achieved.

However, after the nozzle of the tire is placed inside the inflation joint, the nozzle of the tire must be tightened by pressing a lever provided on the inflation joint, so that the nozzle of the tire can be tightly clamped. It can avoid the situation of gas leakage during inflation.

However, the trigger on the general inflation joint is actuated in a horizontal position to be turned up to a vertical position, or is turned down to a horizontal position in a vertical position to clamp the nozzle of the tire or Loose. However, such a lever that is turned from horizontal to vertical or from vertical to horizontal can easily interfere with foreign objects (such as wheel frames, spokes on the wheel frame, etc.), even if the trigger itself is not It will interfere with foreign objects, and the user's hand holding the lever can easily interfere with the foreign object or not. It will not only have problems in the scope of use, but also more easily due to the failure of the trigger. When it is turned, it is caused by the fact that there is a tight clamping between the nozzle of the tire and the tire, which leads to difficulty in inflation.

In view of the above, it is an object of the present invention to provide a horizontally-turned inflation joint that can be rotated in a horizontal state to reduce interference with foreign objects during turning, thereby enhancing Smoothness when inflated.

Accordingly, the present invention provides a horizontally-turned inflation joint that mainly includes a housing, a pressing unit, and a trigger; the pressing unit is disposed in the housing, and the trigger is located outside the housing. And being coupled with the pressing unit, the trigger rod can be horizontally reciprocated between a loose position and a fastening position, and when the pull rod is in the loose position, the pressing unit is loosened. When the trigger rod is in the fastening position, the pressing unit is tightened; thereby releasing or tightening a gas nozzle by a horizontally-trimmed wrench, which can achieve more convenient use.
