In order to realize the above-mentioned purpose, the utility model provides a technical scheme does, a coupling joint for connecting tube, including connecting the body, coupling nut, the one end that connects the body is equipped with sealing washer, gasket, first clamp ring, one side that coupling nut kept away from and connects the body is equipped with the fixed disk, one side threaded connection that the fixed disk is close to coupling nut has lock nut, one side sliding connection who just is located lock nut in the fixed disk has the second clamp ring, the fixed disk with connect through screw rod fixed connection between the body.

Preferably, an accommodating cavity for accommodating the second compression ring is formed in the fixed disk, and a conical surface is arranged on one side, close to the second compression ring, of the fixed disk.

Preferably, one side of the joint body is provided with a fixing groove for accommodating the sealing ring.

Preferably, one side of the central hole of the connecting nut, which is close to the joint body, is provided with a chamfer.

Preferably, the surface of the fixed disc is provided with a through hole for mounting the screw.

Preferably, the surface of the joint body is provided with a threaded hole matched with the screw rod.

The utility model adopts the above technical scheme, beneficial effect includes: this kind of attach fitting for connecting tube realizes connecting the first way of body through the cooperation coupling nut of the first clamp ring that connects body one side to set up, and fixed disk, lock nut and the second clamp ring realization that the rethread set up are fixed on the body, pass through screw rod fixed connection with the fixed disk with connecting the body again, have realized the second way fastening to the body, can bear the axial tension of bigger body, avoid appearing becoming flexible in the use and droing.
