Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 3 and fig. 5, do the utility model discloses a joint of JDG pipeline, including connector body 1, connector body 1's both ends are respectively inserted and are equipped with a JDG pipeline 2 that waits to be connected. The end of the connector body 1 is provided with a deformation groove 11 towards the center, the deformation groove 11 is provided with a plurality of deformation grooves 11, and the deformation grooves 11 are uniformly distributed on the connector body 1 along the circumferential direction of the connector body 1. Every two adjacent deformation grooves 11 divide the end of the connector body 1 into a deformation clamping piece 12, the deformation clamping piece 12 is bent away from the axis of the connector body 1, and a clamping pad 13 (shown in fig. 7) is fixedly connected to the side of the deformation clamping piece 12 facing the axis of the connector body 1. External threads are formed in the end portion of the connector body 1, and the connector body 1 is provided with a fixing pipe 3 which is used for gathering the deformation clamping piece 12 to the middle in a threaded fit mode.

As shown in fig. 5 and 6, a positioning rib 14 is further fixed to the inner circumferential surface of the connector body 1, the positioning rib 14 is located at the midpoint of the connector body 1 in the length direction, and the positioning rib 14 is disposed coaxially with the connector body 1. An inner pipe 4 made of rubber is also inserted into the connector body 1, and after the inner pipe 4 is inserted into the connector body 1, the inner pipe 4 is bent at the connector body 1. Insert into inner tube 4 back when JDG pipeline 2, JDG pipeline 2 can be fixed for the arris spacing to make two inner tubes 4 can be more even distribution inside connector body 1, thereby improved the stability that connects to JDG pipeline 2. Inner tube 4's setting has increased the frictional force between connector body 1 and the JDG pipeline 2 to inner tube 4 is located between deformation clamping piece 12 and the JDG pipeline 2, and when deformation clamping piece 12 pressed from both sides JDG pipeline 2 tightly, inner tube 4 can cushion the rigidity contact between deformation clamping piece 12 and the JDG pipeline 2, thereby can protect JDG pipeline 2.

As shown in fig. 3 and 4, a plurality of shifting pieces 31 for facilitating the worker to screw the fixed pipe 3 are further uniformly and fixedly connected to the outer circumferential surface of the fixed pipe 3, and each shifting piece 31 is arranged along the radial direction of the fixed pipe 3. The setting of plectrum 31 has increased the frictional force between staff's hand and the fixed pipe 3 to made things convenient for the staff to twist, and the staff can also use tools such as spanner to twist plectrum 31, thereby further improved the convenience that fixed pipe 3 used.
