Description

Technical Field

[0001] This application relates to the technical field of internally threaded pipes with stable connections, and more particularly to an internally threaded pipe with stable connections. Background Technology

[0002] Internally threaded pipes, as a common type of pipe fitting, are widely used in water supply and drainage, HVAC, petrochemicals, machinery manufacturing, and many other fields due to their simple structure and convenient installation. They connect to externally threaded pipe fittings or pipes via internal threads at the pipe end, achieving functions such as fluid transport and component fixation. The stability of the connection directly affects the safe operation and service life of the entire system. In practical applications, the connection stability of traditional internally threaded pipes often faces several challenges. On the one hand, the thread machining precision of some internally threaded pipes is insufficient, with deviations in parameters such as thread profile and pitch. This leads to excessive clearance or uneven interference when mating with externally threaded pipe fittings, making them prone to loosening under long-term use or vibration and pressure impacts, resulting in leakage problems. This can cause serious safety accidents, especially when transporting flammable, explosive, or corrosive fluids. On the other hand, the connection structure of traditional internally threaded pipes is relatively simple, mostly relying solely on the friction between the threads for fixation. When encountering extreme conditions such as high temperature and high pressure, the friction between the threads weakens due to factors such as thermal expansion and contraction of materials and wear, further reducing the stability of the connection.

[0003] Furthermore, in fields with high requirements for connection reliability, such as aerospace and precision instruments, traditional internally threaded pipe connection methods are insufficient to meet stringent usage demands. Frequent maintenance and replacement not only increase costs but may also affect the normal operation of the entire system.

[0004] With the continuous development of industrial technology, various fields have placed increasingly higher demands on the stability, sealing, and durability of pipeline connections. Therefore, developing a stable, adaptable, and versatile internally threaded pipe capable of handling various complex working conditions is of significant practical importance for improving the safety and reliability of pipeline systems and reducing maintenance costs, and has become an urgent need for the development of related industries. Those skilled in the art have provided a stable internally threaded pipe to address the problems mentioned in the background section. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a threaded pipe with stable connection.

[0006] This application provides a stable internally threaded pipe using the following technical solution:

[0007] A stable internally threaded pipe includes a pipe body with four rectangular grooves on the outer side. Each rectangular groove has a limiting groove on both sides. A threaded hole is provided on one side of the pipe body, and the threaded hole communicates with the limiting groove. A movable rod is provided inside the rectangular groove, and an L-shaped stabilizing rod is fixedly installed on the outside of the movable rod.

[0008] Preferably, one end of the L-shaped stabilizer extends to the outside of the tube body, and the number of L-shaped stabilizers is four.

[0009] Preferably, guide posts are movably installed on both sides of the movable rod, and one end of the guide post extends into the interior of the limiting groove.

[0010] Preferably, one end of the guide post is fixedly installed with a steel ball inside the limiting groove, and the limiting groove is provided with a threaded sleeve.

[0011] Preferably, the threaded sleeve is externally engaged with a ring, and the ring has a semi-circular groove on its outer surface.

[0012] Preferably, the outer side of the ring is threaded to the inner wall of the limiting groove.

[0013] In summary, this application includes the following beneficial technical effects: when the connecting tool is inserted into the threaded hole, the four L-shaped stabilizing rods extend to one end of the tube body and tightly abut against the outer wall of the connecting tool, forming a clamping force on the connecting tool from multiple directions, thereby effectively preventing the connecting tool from shaking or loosening during use, achieving stable clamping of the connecting tool, and ensuring high stability and reliability of the connection operation.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] The illustrative embodiments and descriptions of the present invention are provided herein to explain the invention, but are not intended to limit the invention.

[0021] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] It should be understood that the terms "comprising / including," "consisting of," or any other variations are intended to cover non-exclusive inclusion, such that a product, apparatus, process, or method that comprises a list of elements includes not only those elements but may also include, where necessary, other elements not expressly listed, or elements inherent to such a product, apparatus, process, or method. Without further limitation, an element defined by the phrases "comprising / including," "consisting of," does not exclude the presence of additional identical elements in the product, apparatus, process, or method that includes said element.

[0023] It should also be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device, component or structure referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of the present invention.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] like Figures 1-4As shown, a stable internally threaded pipe includes a pipe body 1. Four rectangular grooves 2 are provided on the outer side of the pipe body 1. Limiting grooves 3 are provided on both sides of the rectangular grooves 2. A threaded hole 4 is provided on one side of the pipe body 1. The threaded hole 4 communicates with the limiting grooves 3. A movable rod 6 is provided inside the rectangular grooves 2. An L-shaped stabilizing rod 5 is fixedly installed on the outside of the movable rod 6.

[0026] In this embodiment, one end of the L-shaped stabilizer bar 5 extends to the outside of the tube body 1, and there are four L-shaped stabilizer bars 5.

[0027] In this embodiment, guide posts 7 are movably installed on both sides of the movable rod 6, and one end of the guide post 7 extends into the interior of the limiting groove 3.

[0028] In this embodiment, a steel ball 11 is fixedly installed at one end of the guide post 7 inside the limiting groove 3, and a threaded sleeve 8 is provided inside the limiting groove 3.

[0029] In this embodiment, a ring 9 is movably engaged on the outside of the threaded sleeve 8, and a semi-circular groove 10 is formed on the outside of the ring 9.

[0030] In this embodiment, the outer surface of the ring 9 is threadedly connected to the inner wall of the limiting groove 3.

[0031] The implementation principle of a stable internal threaded pipe according to an embodiment of this application is as follows: When the connecting tool is connected to the threaded hole 4 of the pipe body 1, the clamping and stabilizing mechanism is first activated by rotating the ring 9. Since the outer side of the ring 9 is threadedly connected to the inner wall of the limiting groove 3, rotating the ring 9 will cause it to move axially within the limiting groove 3. The semi-circular groove 10 on the outer side of the ring 9 cooperates with the steel ball 11 at one end of the guide post 7. As the ring 9 moves, the semi-circular groove 10 pushes the steel ball 11, thereby driving the guide post 7 to move within the limiting groove 3. The other end of the guide post 7 is connected to the movable rod 6. The movement of the guide post 7 will cause the movable rod 6 to slide within the rectangular groove 2. An L-shaped stabilizing rod 5 is fixedly installed on the outer side of the movable rod 6. Therefore, the sliding of the movable rod 6 will cause the L-shaped stabilizing rod 5 to move synchronously. Since there are four L-shaped stabilizing bars 5, each corresponding to one of the four rectangular slots 2 on the outside of the tube body 1, the four L-shaped stabilizing bars 5 will approach the center of the tube body 1 from different directions. When the connecting tool is inserted into the threaded hole 4, the ends of the four L-shaped stabilizing bars 5 extending to the outside of the tube body 1 will tightly abut against the outer wall of the connecting tool, forming a clamping force on the connecting tool from multiple directions. This effectively prevents the connecting tool from shaking or loosening during use, achieving stable clamping of the connecting tool and ensuring the stability and reliability of the connection operation.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.
