Abstract: The present Freon refilling apparatus for vehicles comprises a tube fitting and a refilling duct. The tube fitting is connected to the refilling duct. The lower end of the tube fitting has a connection port to connect with gas cylinders. A pushrod is movably inserted into the tube fitting in its axial direction. Between the tube fitting and the upper end of the pushrod, there is an operating mechanism which can push the pushrod down to the lower end of the tube fitting. When the pushrod moves downwards, its lower end can make the gas cylinder connected to the tube fitting. The present Freon refilling apparatus for vehicles is applicable to different types of gas cylinders storing Freon. This provides a more convenient way to refill Freon for automobile air conditioners, with a lower cost.

Abstract: A Freon refilling apparatus for vehicles comprises an outer shell and a tube fitting. The tube fitting is secured to a refilling duct, and one end of the tube fitting has a connection port. The apparatus also comprises an operating handle and a pushrod. One end of the operating handle is hinged to the tube fitting, and the other end is a press part. When the press part swings and gets close to the tube fitting, it drives the pushrod to move and open the gas cylinder. A confining plate is also hinged to the press part. The confining plate has an active contact part, while the outer shell has a passive contact part. The active contact part can lean against the passive contact part. The operating handle is locked when that happens.
