Fluid nozzle locking mechanism

摘要

In a fluid spray gun, the fluid nozzle is threadedly attached to the gun body and is covered by an air cap and threaded retaining ring. A latching mechanism is placed in the gun body and removably latches the toothed nozzle in place to prevent rotation due to friction from the air cap and retaining ring. The latch is held in place by the air cap and/or retaining ring but is easily disengaged when the air cap and retaining ring are removed.
