fig. 2 is a schematic diagram of the exploded structure of fig. 1 of the present invention.

In the figure: 1. a metal tube; 2. fastening the tube; 3. a joint; 4. a threaded interface; 5. and (4) calibration.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure, and in order to keep the following description of the embodiments of the present disclosure clear and concise, detailed descriptions of known functions and known parts of the disclosure are omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

Referring to fig. 1-2, an anti-loosening air pipe joint includes a metal pipe 1, a fastening pipe 2 and a joint 3;

the two ends of the metal pipe 1 are both provided with a threaded connector 4, and the connector 3 is connected with the threaded connector 4 through threads on the inner side; the joint 3 is connected with the threaded interface 4 to complete the connection of the air pipe and the metal pipe 1,

the both ends of tubular metal resonator 1 all are equipped with the external screw thread, and the inside of fastening pipe 2 is equipped with the internal thread, the both ends of tubular metal resonator 1 all are equipped with fastening pipe 2, and tubular metal resonator 1 and fastening pipe 2 are threaded connection, connect and be equipped with the external screw thread on 3, and the one end of fastening pipe 2 and connect 3 threaded connection, connect 3 and install on the trachea, rotary joint 3 makes it be connected with hickey 4 to rotatory fastening pipe 2 for fastening pipe 2 and 3 surface connections of rotary joint, and rotary joint 3 is opposite with the installation direction of fastening pipe 2, consequently makes to connect 3 and is difficult to become flexible.

The diameter of the joint 3 is the same as that of the end face of the metal pipe 1, the joint 3 is the same as the external thread of the metal pipe 1, the fastening pipe 2 is rotated in such a way, the fastening pipe 2 can be moved to the joint 3 from the metal pipe 1, and the metal pipe 1 and the joint 3 are fixed.

The terminal surface of tubular metal resonator 1 and the terminal surface that connects 3 all are equipped with scale 5, meet when two scales 5, and tubular metal resonator 1 and joint 3 become an organic whole, and the screw thread on it docks each other, so makes tubular metal resonator 1 and joint 3 fastening back, and external screw thread butt joint on it can make fastening pipe 2 pass through.

And a sealing gasket is arranged on the end surface of the metal pipe 1 to enhance the air tightness.

External screw thread on the tubular metal resonator 1 and the threaded connection 4 go up external screw thread opposite direction, be forward rotation when connecting 3 and threaded connection 4, and fastening pipe 2 is reverse rotation when connecting with connecting 3, through tubular metal resonator 1 and fastening pipe 2 exert one just against two kinds of external forces to joint 3 simultaneously, and connect 3 not hard up and can be held by tubular metal resonator 1 and fastening pipe 2, so make to connect 3 fixed, and can not become flexible.
