Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe technology, specifically to an expansion-lock sealing connection fiberglass pipe assembly. Background Technology

[0002] Fiberglass pipe, also known as glass fiber reinforced plastic pipe, is a composite material pipe made of glass fiber and its products as reinforcing materials and synthetic resin as matrix material through a specific process. It has the advantages of high strength, light weight, corrosion resistance, good insulation performance and long service life. It is widely used in water supply and drainage, chemical industry, power, communication, construction and other fields, and is especially suitable for conveying corrosive liquids or for use in harsh environments. An expansion lock seal connection is a connection method that uses axial force to expand the inner sleeve, thereby achieving a tight fit with the outer sleeve. Its main function is to provide a method for transmitting torque without keyways. It is suitable for high-precision and high-speed applications. The advantages of this connection method include simplifying the manufacturing and installation of the main parts, and the machining of the shaft and hole for installing the expansion sleeve does not require the high precision manufacturing tolerances required for interference fits. The key mechanism of the expansion lock seal connection is to use axial force to cause the inner sleeve to expand, thereby tightly fitting with the outer sleeve to achieve a seal. If the materials of the inner or outer sleeve are structurally uneven, such as uneven force distribution during the fixing process, the force on different parts of the inner sleeve may be inconsistent during the expansion process. This uneven force distribution will lead to uneven contact pressure distribution between the inner and outer sleeves, thus affecting the stability and reliability of the sealing effect. Therefore, an expansion lock seal connection fiberglass pipe assembly is proposed to address the above problems. Utility Model Content

[0016] Please see Figures 1-6 This utility model provides a technical solution: The expansion-lock sealing connection of the fiberglass pipe assembly includes a fiberglass pipe assembly body 1. An expansion-lock assembly 3 is spirally connected to the outer side of the fiberglass pipe assembly body 1 near the front end. The inner side of the expansion-lock assembly 3 is in contact with the outer side of the cast iron assembly 2. The cast iron assembly 2 includes a cast iron connector body 21. An assembly groove 22 is opened on the outer side of the cast iron connector body 21. The expansion-lock assembly 3 includes an operating ring 31. An internal thread 32 is opened on the inner side of the operating ring 31. Stripes 33 are opened on the outer side of the internal thread 32. A sliding groove 34, a guide groove 35 and a reset groove 36 are opened on the inner side of the operating ring 31. A magnetic ramp 38 and a guide strip 39 are slidably connected to the inner side of the sliding groove 34 and the guide groove 35. A spring 37 is fixedly connected to one end of the magnetic ramp 38. The rear end of the magnetic ramp 38 is tightly in contact with the inner side of the assembly groove 22.

[0017] As a further implementation of this solution, the fiberglass pipe assembly body 1 includes a fiberglass pipe body 11, with an external thread 12 on the outer side of the fiberglass pipe body 11, a mounting groove 13 at the front end of the fiberglass pipe body 11, and a sealing rubber ring 14 fixedly connected to the rear end of the mounting groove 13. Through the above settings, the fiberglass pipe assembly body 1 can provide a stable basic structure for the connection of the fiberglass pipe, while the setting of the sealing rubber ring 14 provides a support point for subsequent sealing deformation, ensuring the reliability of the sealing effect. As a further implementation of this solution, an operating ring 31 is sleeved on the outer side of the external thread 12. The outer side of the external thread 12 is spirally connected to the inner side of the internal thread 32. Through the above-mentioned arrangement, the spiral connection design makes the connection between the operating ring 31 and the external thread 12 more secure and easier to adjust. By rotating the operating ring 31, the component can be tightened or loosened, which greatly improves the convenience of installation and disassembly, and also provides operational convenience for achieving uniform sealing effect. As a further implementation of this solution, the cast iron connector body 21 is inserted into the inner side of the mounting groove 13, the rear end of the cast iron connector body 21 is tightly attached to the front end of the sealing rubber ring 14, and the outer side of the assembly groove 22 is engaged with the magnetic ramp 38. Through the above settings, this insertion and engagement design not only realizes the rapid assembly between components, but also ensures the uniform distribution of pressure during the stress process through the tight attachment of the cast iron connector body 21 to the sealing rubber ring 14 and the engagement of the assembly groove 22 with the magnetic ramp 38, thereby effectively improving the stability and reliability of the sealing performance. As a further implementation of this solution, the operating ring 31 is in the shape of a circular ring. The operating ring 31 is sleeved on the outside of the fiberglass pipe body 11. A limit ring is fixed on the inner side of the front end of the operating ring 31. Through the above settings, the stability of the component during axial movement is ensured, and the component is prevented from shifting during the force process, thereby ensuring the uniformity and consistency of the sealing effect. As a further implementation of this solution, the sliding groove 34 and the guide groove 35 are connected, the guide strip 39 is slidably connected to the inner side of the guide groove 35, the magnetic ramp 38 is embedded in the interior of the sliding groove 34, the end of the spring 37 away from the magnetic ramp 38 is fixedly connected to the inner side of the sliding groove 34, the front end of the magnetic ramp 38 is inclined, and the rear end of the magnetic ramp 38 is in close contact with the inner side of the assembly groove 22 near the rear end. Through the above settings, the uniform distribution of sealing pressure is ensured, thereby significantly improving the stability and reliability of the sealing effect, which is especially suitable for application scenarios with high sealing requirements.

[0018] Workflow: To quickly fix the cast iron component 2 and the fiberglass pipe component body 1 while ensuring an airtight seal, the operator aligns the cast iron connector body 21 with the mounting groove 13, brings the cast iron connector body 21 close to the front end of the mounting groove 13, aligns the center of the cast iron connector body 21 with the center of the mounting groove 13, and inserts it into the mounting groove 13. During the backward movement of the cast iron connector body 21, when it comes into contact with the magnetic ramp 38, the cast iron connector body 21 needs to overcome the friction between itself and the magnetic ramp 38, as well as the elastic force of the spring 37. Therefore, the force required is greater than before. This necessitates greater force or multiple people to push the cast iron connector body 21. During this process, due to the squeezing action and the shape of the magnetic ramp 38, the magnetic ramp 38 retracts into the sliding groove 34, squeezing the spring 37. Simultaneously, the guide strip 39 slides inside the guide groove 35, limiting the movement of the magnetic ramp 38. When the assembly groove 22 aligns with the rear end of the magnetic ramp 38, the magnetic... When the magnetic ramp 38 returns to its original position, it is now inside the assembly groove 22. Rotating the operating ring 31, which is helically connected to the external thread 12, causes it to move backward. This movement drives the entire expansion lock assembly 3 backward. The magnetic ramp 38 then presses against the assembly groove 22, i.e., the cast iron connector body 21. The rear end of the cast iron connector body 21 then presses against the front end of the sealing rubber ring 14, causing the sealing rubber ring 14 to deform. The inner side of the sealing rubber ring 14 is hollow. After deformation, ring 14 will fit tightly against the rear end of the cast iron connector body 21, achieving a sealing effect. The locking effect is achieved by the cooperation of magnetic ramp 38 and assembly groove 22. During reset, the existing permanent magnet is placed inside the reset groove 36 and magnetically attracted to the magnetic ramp 38, thereby resetting the magnetic ramp 38 into the sliding groove 34, thus achieving the effect of disassembling the cast iron connector body 21. Based on the above principles, the device not only improves the convenience of fixing, but also ensures the uniformity of pressure during fixing, thereby ensuring the uniformity of sealing performance and improving the stability and reliability of the sealing effect.

[0019] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
