Technical Field

[0001] The utility model relates to the field of antistatic pipelines, in particular to an antistatic pipeline for transmitting chemical raw materials. Background Art

[0002] Anti-static piping is a specially designed piping system designed to prevent or mitigate the generation and accumulation of static electricity, thereby reducing the risk of electrostatic discharge. These pipes are typically used in industrial sites that handle flammable and explosive gases or liquids, such as chemical plants, petrochemical plants, dusty environments, etc.

[0003] A search revealed that Chinese patent publication number CN220457631U discloses an anti-static pipe for transporting chemical raw materials. The pipe includes a connector as a connection carrier, an anti-static mechanism mounted on the inner surface of the connector to prevent static electricity from being generated in the pipe, and a fixing mechanism for securing the pipe is also mounted on the surface of the connector. This utility model utilizes a threaded annular block, making it easy to separate the annular block from the connector and facilitating assembly and disassembly. A connecting pipe of an appropriate length is engaged with the connector, and the threaded column is twisted. The threaded column pushes the bearing and the circular block to slide, pushing the arc block into contact with the surface of the connecting pipe, making it easy to connect the connecting pipe to the connector and installing connecting pipes of varying lengths, resulting in a highly effective solution.

[0004] In the above technology, although the connecting pipe and the connecting head are engaged and the threaded column is turned, the threaded column pushes the bearing and the round block to slide, which can push the arc block to fit the surface of the connecting pipe, making it convenient to connect the connecting pipe and the connecting head, but it is more troublesome to rotate the threaded column to push the bearing and the round block so that the arc block fixes the connecting pipe on the arc block. Therefore, an anti-static pipe for transmitting chemical raw materials is proposed to solve the above problem. Utility Model Content

An annular block 3 is fixedly connected to the outer wall of the connector 4, and the annular block 3 provides support for the sliding of the limit block 5. A sliding groove is provided on the front inner wall of the annular block 3, and the front inner wall of the annular block 3 is elastically connected to the limit block 5 by a spring 16. The limit block 5 is provided with four, and the movement of the limit block 5 drives the arc block 9 and the anti-slip pad 10 to move. The limit block 5 moves toward the center and stretches the spring 16. The rear end outer wall of the limit block 5 is slidably connected to the front end inner wall of the annular block 3, and a slot is provided on the left end outer wall of the limit block 5. One end of the spring 16 is fixedly connected to the front end inner wall of the annular block 3, and the other end of the spring 16 is fixedly connected to the left end outer wall of the limit block 5. The limit ring 2 moves backward to make the limit The positioning block 5 moves toward the center, stretching spring 16. When the limiting ring 2 moves forward, the elastic force of spring 16 pulls the limiting block 5 back to its original position. An arc block 9 is fixedly connected to the outer wall of the right end of the limiting block 5. The arc block 9 is provided with four arc blocks 9. The arc block 9 presses the outer wall of the connecting pipe 1 against the outer wall of the connecting head 4 for connecting the connecting head 4 and the connecting pipe 1. An anti-slip pad 10 is fixedly connected to the outer wall of the right end of the arc block 9. The anti-slip pad 10 is set to increase the friction between the arc block 9 and the connecting pipe 1. The limiting ring 2 is slidably connected to the outer wall of the left end of the limiting block 5. The movement of the limiting ring 2 drives the movement of the limiting block 5. The limiting assembly is elastically connected to the outer wall of the left end of the limiting ring 2 by spring 2 8. The anti-static assembly is fixedly connected to the inner wall of the upper end of the connecting head 4. The front end outer wall of the connecting head 4 is installed with a connecting pipe 1, which is used for transmitting raw materials.

[0032] Reference Figure 3 and Figure 4 The anti-static component includes a fixed column 11. The setting of the fixed column 11 limits the moving direction of the slider 13. The inner wall of the bottom end of the fixed column 11 is elastically connected to the slider 13 through a spring three 12. A through groove is opened on the inner wall of the upper end of the slider 13. The front end of the through groove in the slider 13 is inclined downward.
