[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0021] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0023] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] A pipeline plugger with a functional coating includes a plugger column 1 with a functional coating, a screw 2 fixedly connected to the top of the plugger column 1, a screw sleeve 3 spirally connected to the outer side of the screw 2, a limiting torsion block 4 fixedly connected to the outer side of the screw sleeve 3, and a nut 5 spirally connected to the top of the screw sleeve 3. This arrangement enables the detachable installation of the occluder column 1 and the limiting torsion block 4.

[0026] A gasket 7 is sleeved on the outer side of the screw 2, and the gasket 7 is arranged between the limiting twist block 4 and the nut 5. This arrangement allows the gasket 7 to increase the contact area between the nut 5 and the limiting twist block 4, so that the limiting twist block 4 can be positioned more stably; the outer side of the nut 5 is fixedly connected with an anti-slip sleeve 6, and the anti-slip sleeve 6 fits with the gasket 7. This arrangement increases the friction between the operator's hand and the nut 5 through the anti-slip sleeve 6; the bottom of the limiting twist block 4 is fixedly connected with an elastic silicone pad 8, and a through hole 9 is provided at the center of the elastic silicone pad 8, and the screw 2 passes through the through hole 9. This arrangement enables the elastic silicone pad 8 to be positioned; a number of mounting holes 10 are provided on the inner side of the elastic silicone pad 8, and an elastic sponge block 11 is fixedly connected to the inner side of the mounting hole 10. This arrangement allows the elastic sponge block 11 to absorb part of the energy and reduce the pressure on the elastic silicone pad 8.

[0027] Working process: When using a pipe plug with a functional coating, the conical plug column 1 is usually inserted into the pipe. In order to extend the service life of the occluder column 1, coatings with different functions can be sprayed on the outside of the occluder column 1. Then, the occluder column 1 is rotated by the limiting twist block 4, so that the occluder column 1 gradually moves into the pipe. The occluder column 1 can gradually compress the space in the pipe, thereby achieving a good sealing effect. The limiting twist block 4 can limit the occluder column 1 to prevent the occluder column 1 from being difficult to remove after it has completely entered the pipe. To achieve the sealing of the pipeline, after long-term use, the pipeline plugger with functional coating may be damaged. When the pipeline plugger is to be replaced, the plugger column 1 is first removed from the pipeline, and then the nut 5 is rotated to make the nut 5 spiral away from the gasket 7. The outside of the nut 5 is provided with an anti-slip sleeve 6, which can increase the friction between the operator's hand and the nut 5, so that the operator can rotate the nut 5 more easily when applying the same force, thereby improving work efficiency. Then the nut 5 is removed and the gasket 7 is separated from the screw 2. Then, rotate the limiting twist block 4 so that the limiting twist block 4 drives the screw sleeve 3 to rotate, and the screw sleeve 3 and the screw rod 2 are spirally connected. The screw rod 2 passes through the elastic silicone pad 8 through the through hole 9, so that the limiting twist block 4 drives the elastic silicone pad 8 to gradually move away from the occluder column 1. When the screw sleeve 3 is completely separated from the screw 2, remove the limiting twist block 4 and the elastic silicone pad 8, and the disassembly of the occluder column 1 and the limiting twist block 4 is completed. The use status of the occluder column 1 and the limiting twist block 4 is judged and replaced. The reverse operation can be performed to realize the replacement of the occluder column 1 and the limiting twist block 4. During the installation of the occluder column 1 and the limiting torsion block 4, the occluder column 1 will contact the elastic silicone pad 8. The elastic silicone pad 8 can protect the occluder column 1 and the limiting torsion block 4 to a certain extent, and can enhance the sealing effect of the occluder column 1. There is an elastic sponge block 11 fixed by the mounting hole 10 on the inner side of the elastic silicone pad 8. When subjected to external force, the elastic sponge block 11 can absorb part of the energy and deform, thereby reducing the pressure on the elastic silicone pad 8, so that the elastic silicone pad 8 can undergo greater deformation and is not easily damaged.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
