Freon refilling apparatus for vehicles
First Claim
1. A Freon refilling apparatus for vehicles comprising:
- a tube fitting (3) with a connection part (34);
a refilling duct (4) capable of connecting to automobile air conditioners, the tube fitting (3) connected to the refilling duct (4);
a lower end of the tube fitting (3) with a connection port (353) capable of connecting with gas cylinder;
a pushrod (5) movably inserted into the tube fitting (3) in an axial direction;
an operating handle (61) with a push part (62) capable of pushing the pushrod (5) down to the lower end of the tube fitting (3); and
a confining plate (612) hinged to the operating handle (61) capable of locking the operating handle (61);
wherein when the pushrod (5) moves downwards, a lower end of the pushrod (5) causes the gas cylinder to connect with the tube fitting (3); and
wherein a first end of the operating handle (61) is hinged to the connection part (34), a second end is bent to a side of the tube fitting (3), there is an active push slope (63) on the push part (62) and the active push slope (63) is an oblique plane, an upper end of the pushrod (5) stretches out of the tube fitting (3), there is a passive push slope (53) on the upper end of the pushrod (5) and the passive push slope (53) is an oblique plane, and the active push slope (63) presses against the passive push slope (53) to form plane contact when the confining plate (612) locks the operating handle (61).

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.
