Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2The utility model provides an embodiment: a pipeline positioning structure, including two shells 1 and two guide rails 16, which are usually made of durable metal or plastic, and are used to carry and protect internal mechanical components. The main function is to protect the internal driving mechanism from the influence of the external environment. The two shells 1 are fixedly connected to the far side with a protective shell 2, the inner rotation connection of the shell 1 is a central shaft 3, and the outer side of the central shaft 3 is fixedly connected to a worm gear 4. A driving assembly is arranged inside the protective shell 2, and the driving assembly includes a worm 5. The entire pipeline positioning structure is rotated by the rotation of the worm 5. The outer side of the worm 5 is rotationally connected to the inside of the protective shell 2, and the outer side of the worm 5 is fixedly connected to a rotating handle 6, and the outer side of the rotating handle 6 is rotationally connected to the inside of the protective shell 2. The outer side of the worm 5 is meshed with the outer side of the worm gear 4, and the meshing with the worm gear 4 can convert the rotational motion. The inner side of the shell 1 is slidably connected to two sliding columns 8, and the adjacent side of the two sliding columns 8 is fixedly connected to a positioning head 9, which is used to accurately position the pipeline to ensure that the pipeline In order to ensure the accuracy and stability of the road during operation, two limit rods 10 are fixedly connected to the bottom of the sliding column 8, an H-type follower block 11 is movably connected to the inside of the shell 1, and a round head rod 12 is slidably connected to the inside of the H-type follower block 11, and an eccentric concave cam 7 is fixedly connected to the outside of the central axis 3. The special design makes it interfere with the round head rod 12 in contact with the bottom during rotation, so that it moves up and down. The outside of the eccentric concave cam 7 contacts the top of the round head rod 12, and the outside of the round head rod 12 is fixedly connected to two limit plates 13. The bottom of the round head rod 12 is fixedly connected to an elastic component to provide power for the top structure, so that the round head rod 12 is in close contact with the top structure. The elastic component includes a strong spring 14, which is arranged inside the shell 1, one end of the strong spring 14 is fixedly connected to the bottom of the round head rod 12, and the other end of the strong spring 14 is fixedly connected to the bottom of the inner wall of the shell 1. A tube body 15 is arranged on the top of the two shells 1, and the outside of the tube body 15 contacts the outside of multiple positioning heads 9.

[0024] Reference Figure 1 and Figure 2 The left and right sides of the outside of the guide rail 16 are fixedly connected to the limit strips 17, so that the external sliding structure will not deviate. The outside of the guide rail 16 is slidably connected to a sliding block 18, and the inside of the sliding block 18 is rotatably connected to a plurality of balls 19 for reducing friction. The internal thread of the sliding block 18 is connected to two fixed anchor bolts 20, and the outside of the balls 19 contacts the inner wall of the top groove of the guide rail 16, and the outside of the balls 19 contacts the inner wall of the groove opened by the sliding block 18. The external threads of the fixed anchor bolts 20 are connected to the inside of the sliding block 18, and the adjacent sides of the two fixed anchor bolts 20 are respectively in contact with the left and right sides of the guide rail 16, so that the sliding block 18 on the guide rail 16 can stop moving through the contact force.

[0025] Compared with some devices in the prior art, the above content drives the worm wheel 4 meshing with the worm 5 to rotate by controlling the rotating handle 6. During the rotation of the worm wheel 4, the eccentric concave cam 7 fixed outside the central axis 3 is driven to rotate, so that the round head rod 12 in contact with the bottom drives the external H-shaped follower block 11 to move, and under the action of the limit rod 10, the positioning head 9 on the sliding column 8 is positioned for pipes of different diameters.

[0026] Working principle: At the beginning of the operation, the operator turns the handle 6, which is connected to the worm 5. The rotation of the worm 5 transmits power through its meshing with the worm wheel 4, thereby driving the eccentric concave cam 7 on the central shaft 3 to rotate. The design of the eccentric concave cam 7 makes it interfere with the round head rod 12 at the bottom during rotation, pushing the round head rod 12 to move up and down.

[0027] The movement of the round head rod 12 is transmitted to the sliding column 8 through the H-shaped follower block 11 connected thereto. Positioning heads 9 are fixed inside the sliding column 8, which are in direct contact with the pipe and are accurately positioned according to the diameter of the pipe. The bottom of the sliding column 8 is connected to the structure inside the housing 1 through a limiting rod 10 to ensure the stability of the sliding column 8 and limit its range of motion.

[0028] In addition, the guide rail 16 of the device ensures the stability of the entire sliding structure and prevents deviation through the limit bar 17. The sliding block 18 on the guide rail 16 is internally connected with a plurality of balls 19 for rotation, which reduce the friction during sliding, making the movement of the sliding block 18 smoother and more precise. The sliding block 18 is fixed by fixing anchor bolts 20 connected by internal threads, which contact the left and right sides of the guide rail 16 and prevent further movement of the sliding block 18 through contact force.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
