[0002] In industrial pipeline systems, spiral pipes are widely used in various fluid conveying scenarios such as petroleum, chemical industry, construction, etc. due to their unique structure and good performance. The connection of spiral pipes with other equipment or pipelines is crucial during actual installation and use.

[0003] When connecting components with flanges, traditional spiral pipes usually need to be rotated to adjust the position of the flange hole so that it aligns with the hole position of another flange. However, spiral pipes are often large in size and heavy in weight, making rotation extremely difficult. Not only does it consume a lot of manpower and time, but it also easily causes damage to the spiral pipe or loose connection due to improper operation. In some space-limited installation environments, it is almost impossible to rotate the spiral pipe, which greatly hinders the installation and maintenance of the pipeline system.

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] Embodiment one

[0021] Please refer to Figs. 1-3 The utility model provides a spiral tube with adjustable connecting piece, including spiral tube body 1, both ends of spiral tube body 1 are connected with the connecting flange 2, the side away from spiral tube body 1 of connecting flange 2 is equipped with the sliding slot 3, the one side of sliding slot 3 is equipped with the limiting hole 4, the inside sliding installation of sliding slot 3 has the sliding block 5, and the limiting block 6 of sliding block 5 one side welding is equipped with in the limiting hole 4,

[0022] The surface of sliding block 5 is provided with a first flange hole 7, and the surface of limiting block 6 is provided with a second flange hole 8.

[0023] Specifically, the position of the sliding block 5 is changed by the rotating assembly, and the position of the limiting block 6 is changed, so that the first flange hole 7 and the second flange hole 8 are changed in position, and the first flange hole 7 and the second flange hole 8 are connected to the flange hole of the other flange.

[0024] The rotating assembly includes an annular rotating plate 10, which is rotatably installed on the outside of the spiral tube body 1. A plurality of L-shaped connecting rods 9 are fixedly installed on the outside of the annular rotating plate 10. One end of the L-shaped connecting rod 9 is fixed between the sliding block 5. A threaded member is arranged on the surface of the annular rotating plate 10 to abut against the outside of the spiral tube body 1. The threaded member is specifically a threaded abutting rod 11, which is threadedly connected to the outside of the annular rotating plate 10. Rotating the threaded abutting rod 11 can change the position of the threaded abutting rod 11. When the threaded abutting rod 11 abuts against the outer wall of the spiral tube body 1, the annular rotating plate 10 can be fixed to the outside of the spiral tube body 1. When the threaded abutting rod 11 does not abut against the outer wall of the spiral tube body 1, rotating the annular rotating plate 10 can drive the L-shaped connecting rod 9 and the sliding block 5 to move.

The sliding block 5 cannot move in the direction close to the annular rotating plate 10 through the limiting hole 4. The annular rotating plate 10 abuts against the connecting flange 2 on one side, so that the annular rotating plate 10 cannot move in the direction close to the sliding block 5. Therefore, the annular rotating plate 10 can only rotate on the outside of the spiral tube body 1, so that the sliding block 5 remains in the sliding slot 3.

[0026] The first flange hole 7 corresponds to the second flange hole 8 in position, and the inner diameters of the first flange hole 7 and the second flange hole 8 are the same. When the flanges are connected by bolts, the connection work can be carried out through the first flange hole 7 and the second flange hole 8.

[0027] Working principle: the utility model discloses a spiral pipe with adjusting connecting piece, when connecting, the flange to be connected and the connecting flange 2 position correspond, and are connected through bolt, when needing to adjust flange hole position, first rotate threaded abutment rod 11 so that threaded abutment rod 11 does not abut spiral pipe body 1 outside, annular rotating plate 10 can rotate at this moment, rotate annular rotating plate 10 and drive L-shaped connecting rod 9 movement, so that L-shaped connecting rod 9 drive sliding block 5 slide in sliding slot 3 inside, thereby drive limit block 6 movement, so that multiple first flange hole 7 and second flange hole 8 position synchronous change, adjust flange hole position conveniently, make it with the flange hole position of another flange correspond,

[0028] After adjusting, rotate threaded abutment rod 11, so that threaded abutment rod 11 is tightly abutted on the outer wall surface of spiral pipe body 1, so that the position of annular rotating plate 10 is fixed, thereby the position of L-shaped connecting rod 9, sliding block 5 and limit block 6 is fixed, guarantee the stability of subsequent connection.
