Detailed Description

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

Example (b): as shown in the figures 1-4 of the drawings,

the utility model provides a pipeline elbow, including connecting section of thick bamboo portion 1, with the kink 2 of connecting section of thick bamboo portion 1 both ends integrated into one piece and with kink 2 integrated into one piece's tip 3, tip 3's the central axis is 112.5 with the contained angle between the central axis of connecting section of thick bamboo portion 1, a plurality of joint structure that are used for with opposite side end 3 be connected of 3 fixedly connected with of a side end, be connected through joint structure between the tip 3 that is located on different connection section of thick bamboo portion 1, joint structure includes the arc piece 6 with 3 inner wall fixed connection of tip, fixedly connected with arc between the adjacent arc piece 6, a drum is constituteed to a plurality of arc pieces and arc piece 6, one side fixedly connected with arc piece 7 of tip 3 central axis is kept away from to arc piece 6, set up a plurality of caulking grooves.

Be equipped with external screw thread 10 on 3 periphery walls of tip with caulking groove 9, be equipped with screw thread section 8 on the periphery wall of arc piece 7, when arc piece 7 inlays in caulking groove 9, external screw thread 10 is located same thread with screw thread section 8, external screw thread 10 threaded connection has a screw thread section of thick bamboo 5, screw thread section of thick bamboo 5 and external screw thread 10, during 8 threaded connection of screw thread section, screw thread section of thick bamboo 5 shields the clearance between caulking groove 9 and the adjacent tip 3, tip 3 that has caulking groove 9 is close to 2 one side fixedly connected with fist retaining ring 4 of kink.

The surfaces of the connecting cylinder portion 1, the bent portion 2, the end portion 3, and the threaded cylinder 5 are coated with a protective coating of polyurea paint.

When people need to use the elbow to connect a pipeline at an angle of 90 degrees, people can sleeve the end part 3 of the elbow with a pipe fitting and connect the elbow with the pipeline in an interference fit mode, and because the surfaces of the connecting barrel part 1, the bending part 2, the end part 3 and the threaded barrel 5 are coated with the protective coating of polyurea coating, the protective coating can play a good protection effect on the elbow, so that the elbow is not easy to corrode, the elbow has longer service life, and when the elbow needs to connect a pipeline at an angle of 180 degrees, people can take two elbows, embed the arc-shaped block 7, the arc-shaped plate and the arc-shaped sheet 6 on one elbow into the end part 3 of the other elbow, which is provided with the caulking groove 9, and make the arc-shaped block 7 be embedded into the caulking groove 9, then people rotate the threaded barrel 5, thereby enabling the thread cylinder 5 to be in threaded connection with the external thread 10 and the thread section 8 until the thread cylinder 5 abuts against the retainer ring 4, at the moment, the thread cylinder 5 can shield a gap between the caulking groove 9 and the end parts 3 at two sides, preventing the leakage between the two elbows, then people enable the pipelines to be connected with the end parts 3 at two ends of the two assembled elbows in an interference fit mode, thereby enabling the pipelines to be connected well, and when people need to connect the two pipelines to prolong the length of the pipelines, people only need to extrude the arc-shaped block 7, and enable the arc-shaped block 7 to drive the arc-shaped piece 6 to generate elastic deformation, so that the arc-shaped block 7 returns to the end parts 3, and one elbow is rotated, then the arc-shaped block 7 is not blocked by the inner wall of the end part 3, the arc-shaped piece 6 releases elastic potential energy and pushes the arc-shaped block 7 to be embedded into the caulking groove, then people rotate a screw thread section of thick bamboo 5, make it with external screw thread 10 and 8 threaded connection of screw thread section can to make this elbow can carry out multiple equipment assembly, adapt to different situation, and this elbow all adopts plastic material as an organic whole shaping formula structure.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
