Transduction causes gas leakage.
Utility model content
To solve the technical issues of existing pressurizer quick coupling is easy to produce gas leakage, the utility model devises a kind of spiral shell
Line linking Medical pressurizer quick coupling.
The utility model adopts the following technical solution:
A kind of screw connected Medical pressurizer quick coupling, including the first quick coupling, the second quick coupling and sealing
Circle, characterized in that first quick coupling tail portion is provided with the first connection card convex, and first quick coupling head is provided with
Connecting tube is provided with connection external screw thread in the connecting tube, and second quick coupling tail portion is provided with connecting hole, the connection
Connection internal screw thread is provided in hole, second quick coupling head is provided with the second connection card convex, first quick coupling
Connecting tube be fixedly connected with the connecting hole of second quick coupling, sealing is installed at the connecting tube and connecting hole cooperation
Circle, the second quick coupling middle part are provided with connecting shaft, and the connecting shaft is fixedly mounted on cabinet inner wall.
Preferably, first quick coupling tail portion is connected by the first connection card convex with the outer silicone tube of cabinet,
Second quick coupling head is connect by the second connection card convex with silicone tube in cabinet.
Preferably, being provided with connection external screw thread in the connecting shaft, the connecting shaft is close to the second quick coupling tail portion
Side is provided with the shaft shoulder, and the connecting shaft passes through cabinet hole and is fixedly connected by attaching nut with cabinet inner wall.
Preferably, bow-shaped structural is presented in the cross section of the connecting shaft.
Preferably, the connecting tube is to be threadedly coupled with the type of attachment of connecting hole.
Preferably, the material of the sealing ring is rubber.
The beneficial effects of the utility model are: 1, pass through the first quick coupling and the second quick coupling and use the company of being threadedly engaged
It connects, the gas leakage hidden danger that the form of setting sealing ring eliminates quick coupling itself at cooperation；2, connecting shaft is designed into archwise knot
Structure is attached with cabinet, and ensure that the second quick coupling in connected state and will not rotate leads to gas leakage or even fall off.
