Description

Adjustable connector

The present invention relates to an adjustable connector, and more particularly to a connector for connecting a valve of a refrigerant tube to fill a refrigerant.

As shown in FIG. 9, the connector for connecting the valve of the refrigerant tube is a body 91 having a connecting portion 92 at one end for receiving the valve mouth 93 and a knob at the other end of the body 91. 94, the knob 94 is connected to a valve needle 95 extending in the body 91, and the knob 94 is rotated to urge the valve needle 95 to push the ejector pin 96 in the valve mouth 93 toward the valve nozzle 93 to fill the refrigerant into the refrigerant tube. After the refrigerant filling is completed, the knob 94 can be reversely rotated to withdraw the pushing of the ejector pin 96 by the valve needle 95, so that the body 91 and the refrigerant tube are not electrically connected.

If the refrigerant is highly flammable, if the body 91 and the refrigerant tube are leaked due to an accident, the knob 94 must be quickly turned to retreat the valve needle 95 to prevent the refrigerant from inadvertently contacting the fire source and burning. However, the operation of retracting the needle 95 by the rotation of the knob 94 is difficult to complete quickly, and the refrigerant cannot be shortened due to the leak time, and the risk of burning in contact with the fire source is relatively increased.

In addition, when the body 91 is sleeved to the valve mouth 93 by the sleeve portion 92, the fixing device is usually used as a positioning. For example, when the sliding sleeve 97 is in the position shown in the figure, the socket portion 92 and the valve nozzle 93 can be separated. If the sliding sleeve 97 is accidentally touched, it is easy to move in the direction of the knob 94, so that the socket portion 92 and the valve mouth 93 can be easily disengaged due to the loss of positioning, thereby causing the leakage of the refrigerant.

Therefore, how to solve the problem of the above-mentioned conventional connector is the focus of the present invention.
