Description

Technical Field

[0001] The utility model belongs to the technical field of joints, and in particular relates to a horizontal rotary joint based on the inner wall of an externally threaded nut. Background Art

[0002] Joints are very common pipe connection components. During the pipe connection process, conventional joints are fixed in position and orientation to the connected pipe or pipe after the pipe is connected. This often leads to connection difficulties due to misalignment between the joint and other components. Furthermore, joints are a widely used, fundamental component and currently suffer from relatively high manufacturing costs. Addressing these issues has been a topic of research for those skilled in the art. Utility Model Content

[0003] The utility model provides a horizontal rotary joint based on the inner wall of an externally threaded nut, which has a simple structure, can be horizontally rotated after the joint is connected to a pipeline or a pipe fitting, and has low manufacturing cost.

[0004] A horizontal rotary joint based on the inner wall of an externally threaded nut comprises an externally threaded nut, wherein the inner wall of the externally threaded nut is fitted in contact with the outer wall of a sealing ring, the inner wall of the sealing ring is engaged with the connecting column of the connecting joint, one axial end of the inner wall of the externally threaded nut is provided with a first end face with a reduced aperture extending inward, the other axial end of the inner wall of the externally threaded nut is provided with a horizontally arranged groove, the inner side of the first end face is fitted in contact with the second end face of one axial end of the connecting column, the groove is engaged with a horizontally arranged retaining spring, and the retaining spring limits the third end face of the other axial end of the connecting column; the connecting column rotates horizontally along the inner wall of the externally threaded nut. This horizontal rotary joint based on the inner wall of the externally threaded nut uses the inner wall of the externally threaded nut as the connecting section of the joint, abandoning the traditional design structure that uses the connecting pipe as the connecting section. The externally threaded inner wall is directly used as the connecting section to shorten the entire connection length between the externally threaded nut and the joint. That is, the original externally threaded nut and its integrated connecting pipe are changed to only the externally threaded nut, which greatly reduces the manufacturing cost. The axial limits of the two axial end faces of the connecting column limit the axial displacement, ensuring the performance of the joint being able to rotate 360 ​​degrees radially, that is, horizontally, so that after the externally threaded nut is connected to the pipe or pipe fitting, the joint can also be rotated horizontally to improve the adaptability of the connection angle.

[0005] The outer circumference of the external thread nut is provided with an external thread, and one end of the external thread is provided with an enlarged hexagonal column, which facilitates the fastening performance of the connection between the external thread nut and the pipe or pipe fitting.

[0006] The joint is a 90-degree bent pipe, and the bent pipe structure is more conducive to adjusting the radial rotation angle of the joint.

[0007] The external thread nut and the joint are both made of copper.

[0008] The utility model adopts the inner wall of the external threaded nut as the connecting surface to connect the connecting column of the joint through a sealing ring, which greatly shortens the length required for the connection between the joint and the nut and reduces the manufacturing cost. The retaining spring cooperates with the first end face to limit the axial displacement of the connecting column, and the joint can be rotated horizontally to improve the convenience of connection.

[0013] The following is combined with Figure 1-3 The specific implementation method further describes the technical solution of this patent in detail.

[0014] A horizontal rotary joint based on the inner wall of an externally threaded nut includes an externally threaded nut 2, wherein the inner wall 12 of the externally threaded nut is in contact with the outer wall of a sealing ring 9, which in turn engages with the connecting post 7 of the joint 1. A first end face 11 with a narrowed, inwardly extending aperture is provided at one axial end of the internal wall 12 of the externally threaded nut, and the inner side of the first end face 11 engages with the second end face 8 at one axial end of the connecting post 7. A horizontally disposed retaining groove 10 is provided at the other axial end of the internal wall 12 of the externally threaded nut, which engages with a horizontally disposed retaining spring 4. The retaining spring 4 limits the third end face 6 at the other axial end of the connecting post 7, allowing the connecting post 7 to rotate horizontally along the internal wall 12 of the externally threaded nut.

[0015] As a preferred structure, the outer circumference of the external thread nut 2 is provided with an external thread 3, and one end of the external thread 3 is provided with an expanded hexagonal column 5. The joint 1 is a 90-degree bent pipe. The manufacturing material of the external thread nut 2 and the joint 1 is copper.
