Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 3, according to an embodiment of the present invention, a connecting elbow includes: elbow body 1, elbow body 1's both ends are equipped with first link 2 and second link 3 respectively, and the top of first link 2 extends and forms grafting portion 21 towards its extending direction, and the top of grafting portion 21 extends outwards and forms joint portion 22, is equipped with the connection lantern ring 4 on the grafting portion 21, connects the inside wall joint of lantern ring 4 and joint portion 22, is equipped with on the connection lantern ring 4 with the first sealed recess 41 of joint portion 22 assorted.

The utility model discloses a connecting elbow, at the top surface of first connection end 2 towards its extending direction extension formation grafting portion 21, the top of grafting portion 21 extends outwards and forms joint portion 22, and cup jointed the connecting lantern ring 4 on grafting portion 21, wherein the connecting lantern ring 4 can rotate on grafting portion 21, thereby make the bolt connection hole position of connecting elbow and the flange on the pipeline of treating the connection better match, reach the effect of quick connection installation; further, sealing grooves are respectively arranged between the connecting sleeve ring 4 and the clamping portion 22, between the inserting portion 21 and the first connecting end 2 and on the top surface of the clamping portion 22, and a sealing layer 211 is arranged on the inner side wall of the inserting portion 21, so that the installation sealing performance and the service cycle of the connecting elbow are improved.

As shown in fig. 1 to 3, a step 23 is disposed at a boundary between the insertion part 21 and the first connection end 2, a second sealing groove 24 is disposed on the step 23, and when a pipe to be connected is inserted into the insertion part 21 and abuts against the step 23, the second sealing groove 24 is used for increasing the sealing property between the insertion part 21 and the pipe.

As shown in fig. 2 and 3, a third sealing groove 221 is formed on the top surface of the clamping portion 22, and when the diameter of the pipe to be connected is the same as that of the clamping portion 22, the third sealing groove 221 can increase the sealing property between the clamping portion 22 and the pipe.
