Description

Technical Field

[0001] This utility model relates to a plastic pipe product, particularly a grounding and static-conducting pipe fitting for a steel-reinforced composite plastic pipe. Background Technology

[0002] Currently, steel-reinforced composite plastic pipes are widely used in municipal and industrial fields, and have also found some application in underground mines. However, most mines require plastic pipes with conductive materials to prevent electrostatic sparks. Achieving conductivity in plastic materials requires the addition of a large amount of conductive carbon black, which directly affects the performance of the pipes, especially their pressure resistance, and drastically reduces their lifespan. Since steel-reinforced composite plastic pipes have a steel skeleton structure, theoretically, the static electricity accumulated in the plastic will be conducted away through the steel skeleton. Furthermore, since the steel-reinforced plastic composite pipe is a structure in which steel material is completely encased within the plastic material, it is necessary to develop a pipe fitting product that can connect the internal steel skeleton and the external grounding wire. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a pipe fitting product that can discharge static electricity from a steel-reinforced plastic composite pipe.

[0004] To achieve the above objectives, the technical solution of this utility model is: a steel-framed composite plastic pipe grounding and static electricity conducting pipe fitting, which consists of a plastic pipe body, rubber sealing rings, terminals and metal probes, wherein the metal probes always maintain contact with the wires of the terminals, and the rubber sealing rings consist of at least two rings, with the outermost two rubber sealing rings encompassing the entire area of ​​the metal probes.

[0005] The outstanding advantages of this utility model are: simple structure, simple operation, no impact on the pressure-bearing performance of the pipe, and the ability to reduce the use of conductive plastic pipes with greater processing difficulty in mines, thereby increasing the service life of the pipeline in the mine. Attached Figure Description

[0006] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a structural schematic diagram of the application of this utility model. Detailed Implementation

[0007] like Figure 1 , Figure 2 As shown, the steel-framed composite plastic pipe grounding and static electricity conducting pipe fitting consists of a plastic pipe body 1, a rubber sealing ring 2, a terminal block 3, and a metal probe 4. The metal probe 4 always maintains contact with the wire of the terminal block 3. The rubber sealing ring 2 consists of at least two rings, and the outermost two rubber sealing rings 2 encompass the entire area of ​​the metal probe 4.

[0008] In use, the steel-framed composite plastic tube is inserted into this utility model, and then the metal probe 4 is hammered in until it contacts the steel frame in the steel-framed composite plastic tube. The hole can be sealed with molten plastic or sealant. At this point, the static electricity accumulated in the plastic material can be conducted to the terminal 3 through the steel frame and discharged.

[0009] The advantages of this solution compared to existing technologies are: simple structure, simple operation, no impact on the pressure-bearing performance of the pipe, and reduced use of conductive plastic pipes with high processing difficulty in mines, thus increasing the service life of the pipeline in mines.
