[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.
[0016] See also Figures 1 to 3 The utility model provides a technical solution: a steel pipe connector, including a steel ring 1, the number of steel rings 1 is two, and the two steel rings 1 are both installed with: a sealing ring 2, an annular fixing piece 3, a supporting mechanism and a fixing mechanism. The two sealing rings 2 are respectively fixedly arranged on one side of the two steel rings 1, and the outer sides of the outer walls of the two sealing rings 2 are both provided with inclined surfaces; one end of the two annular fixing pieces 3 are respectively fixedly arranged on one side of the two steel rings 1; the supporting mechanisms are respectively arranged on the two annular fixing pieces 3 in a circular array; the fixing mechanism is sleeved on the connection between the two steel rings 1 and the steel pipe.
[0017] In the specific implementation process, it should be noted that when two steel pipes are connected, when preparing to connect the two steel pipes, one end of the steel pipe is inserted into the outer side of the outer wall between the two sealing rings 2, and the edge of the steel pipe contacts the inclined surface on the sealing ring 2. The setting of the inclined surface can guide the steel pipe to the correct position, ensure that the steel pipe is coaxial with the annular fixing member 3, and achieve precise docking. Provide additional stability and support for the steel pipe through the support mechanism. Use the fixing mechanism to tightly fit the two steel rings 1 and the connection of the steel pipe together to ensure the sealing and firmness of the connection. At the connection of the steel pipe, due to the action of external forces such as pressure, tension or bending force, the steel pipe may be deformed, which will affect the stability and sealing of the connection. To prevent this from happening, the support mechanism is used to provide additional support to the inner side of the steel pipe connection. When the external force acts on the steel pipe, the support mechanism can provide uniform support force to prevent the steel pipe connection from being excessively deformed when under pressure. This support not only helps to maintain the original shape of the steel pipe, but also helps to maintain the accuracy and integrity of the connection, thereby ensuring the strength and reliability of the entire structure and preventing leakage or other safety hazards caused by deformation. The steel pipe connector can effectively connect two steel pipes while maintaining the stability and sealing of its structure to prevent leakage or other connection problems.
[0018] In some examples, further, the supporting mechanism includes: threaded rods 4, adjusting caps 5 and arc-shaped supports 6, a number of threaded rods 4 are respectively screwed on two annular fixing members 3 in a circular array; a number of adjusting caps 5 are respectively screwed on the ends of a number of threaded rods 4 and are located on the inner sides of the two annular fixing members 3; a number of arc-shaped supports 6 are respectively rotatably arranged on one end of a number of threaded rods 4.
[0019] During the specific implementation process, it should be noted that when the steel pipe is ready to be in place and located on the sealing ring 2 with an inclined surface, the setting of the inclined surface ensures that the steel pipe and the steel ring 1 remain coaxial; the annular fixing part 3 is located on the inner side of the steel pipe, ready for adjustment of the supporting mechanism; the operator uses a suitable external tool, such as a wrench or a screwdriver, to rotate the adjusting cap 5; as the adjusting cap 5 rotates, the threaded rod 4 connected thereto also begins to rotate and expands outward along the thread direction; the expansion action causes the arc support 6 to move toward the inner wall of the steel pipe and fit closely therewith, thereby providing uniform supporting force; by continuing to rotate the adjusting cap 5, the length of the threaded rod 4 and the degree of fit of the arc support 6 can be fine-tuned until the ideal support effect is achieved, ensuring that the steel pipe connection remains stable without being affected by external forces, providing strong internal support, avoiding leakage or other problems caused by deformation, and ensuring the firmness and reliability of the overall connection.
[0020] In some examples, further, the fixing mechanism includes: a fixing member 7, a protrusion 8 and a bolt 9, the two fixing members 7 are semicircular in shape and are respectively mounted on the two steel rings 1 and the flanges on the outside of the steel pipe; a plurality of protrusions 8 are respectively fixed at both ends of the two fixing members 7 in a group of two, and the protrusions 8 at the ends of the two fixing members 7 fit together; a plurality of bolts 9 are respectively screwed on the plurality of protrusions 8, and a plurality of bolts 9 are provided with nuts 10.
[0021] In the specific implementation process, it should be noted that after the steel pipe and the steel ring 1 complete the internal support through the support mechanism and ensure the accurate position, the fixing mechanism begins to play a role; the fixing member 7 is designed to be semicircular to adapt to the flange structure on the outside of the steel pipe; during operation, the two semicircular fixing members 7 are respectively mounted on the two steel rings 1 and the flange on the outside of the steel pipe to form a tight package; the several protrusions 8 located at both ends of the fixing member 7 correspond to each other and fit together, and the operator uses bolts 9 to connect the two fitting protrusions 8 together; each bolt 9 passes through the corresponding protrusion 8 and is tightened by a nut 10; during the tightening of the bolt 9, the fixing member 7 will be pulled toward the steel pipe and the steel ring 1, so that the contact between them is closer, thereby ensuring the firmness and sealing of the connection; it can not only effectively fix the steel pipe and the steel ring 1, but also resist the separation force caused by the fluid pressure in the pipeline to ensure the safe operation of the pipeline; through the above-mentioned working process, the fixing mechanism can provide a stable and easy-to-maintain connection method for the steel pipe connector, greatly improving the reliability and durability of the pipeline connection.
[0022] In some examples, further, a limiting groove 11 is provided on the inner side of the two fixing members 7, and the corners of the limiting groove 11 are provided with an inclined structure. When the two protrusions 8 are tightly fitted by the bolts 9, the guide bolts 9 squeeze the two steel pipes toward the middle during the tightening process, thereby improving the sealing and strength of the connection; the inclined structure enables the fixing members 7 to shrink inward under the action of the bolts 9, thereby achieving a closer contact between the steel pipes, effectively reducing the possibility of leakage, and enhancing the ability to resist external stress; this squeezing effect also helps to prevent displacement during pipeline operation, maintain the stable position of the steel pipe, and simplify the installation process, so that the operator can intuitively ensure the tightness of the connection by tightening the bolts 9; the squeezing effect of the inclined structure when the two protrusions 8 and the bolts 9 are tightly fitted greatly improves the sealing effect and connection reliability of the steel pipe connector, providing a strong guarantee for the safe operation of the steel pipe.
[0023] In some examples, further, the inner diameter edges of the two steel rings 1 are provided with a slot 12, and a rubber ring 13 for sealing is provided at the slot 12 to improve the sealing performance of the connector and ensure the reliability and long-term stability of the connection; the rubber ring 13 is compressed when the steel pipe is inserted into the steel ring 1, and fits tightly on the outer wall of the steel pipe. The elasticity of the rubber ring 13 enables it to fill the tiny gap between the steel pipe and the steel ring 1, forming an effective sealing barrier to prevent medium leakage; the rubber material has good corrosion resistance and adaptability, can withstand temperature changes and vibrations during pipeline operation, and ensure the long-term durability of the sealing effect; the rubber ring 13 is easy to install and replace, convenient for maintenance, and extends the service life of the connector; its adaptability also makes the connector compatible with steel pipes of different diameters, improving versatility; the rubber ring 13 in the slot 12 can withstand a certain pressure, ensuring that the connection remains stable under pipeline pressure fluctuations or impact loads, providing higher safety and reliability; the slot 12 and rubber ring 13 on the inner diameter edge of the steel ring 1 provide strong sealing protection.
