Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation technology, and more specifically to a pipe elastic interlocking connection mechanism and a corresponding pipe connection device. Background Technology

[0002] In agricultural irrigation, various bridging or branch connections are often required for irrigation pipelines. For example, when pipeline length is limited, bridging is necessary to extend the pipeline. Additionally, when branching off from the main pipeline, fittings such as tees are used to connect the irrigation pipes. One method of connecting pipelines using fittings is by bonding the fittings to the pipe. This type of connection is permanent and can only be used continuously within the same plot of land; it cannot be recycled and rearranged for reuse, and it creates difficulties when rearranging irrigation pipelines. This bonded connection method is not only inconvenient to use but also results in waste of both pipes and fittings.

[0003] In addition, some pipes and fittings are connected by bolts and nuts, which increases the friction between the threads or between the bolt head and the nut end face to prevent loosening. Although this connection method facilitates repeated disassembly and reuse of the pipes, it has poor reliability. As the working time increases, vibration or other disturbances during irrigation operations often cause the threaded connection to loosen, resulting in unstable pipe connections or leakage of irrigation fluid.

[0004] Therefore, there is a need in the prior art to provide a solution that can prevent the connection between the pipe fitting and the pipe from loosening, so that the irrigation pipe can still maintain a good sealing relationship after a certain period of use, thereby ensuring that it can be used for a long time without failure. Summary of the Invention

[0005] To address at least one of the aforementioned technical problems, embodiments of the present invention provide a pipe elastic interlocking connection mechanism. This mechanism not only prevents loosening between connecting pipe fittings but also facilitates the disassembly of the fittings, thereby enabling the repeated use of the fittings and related connection mechanisms, improving equipment utilization, and reducing operating costs.

[0006] The pipe elastic interlocking connection mechanism according to the present invention is used to connect the end of a first pipe fitting and the end of a second pipe fitting, thereby enabling fluid communication between the first pipe fitting and the second pipe fitting, characterized in that the pipe elastic interlocking connection mechanism comprises:

[0007] An external thread portion is provided at the end of the first pipe fitting;

[0008] A radial flange is provided adjacent to the external thread portion. The radial flange protrudes outward from the peripheral wall of the first pipe fitting along the radial direction of the first pipe fitting. The radial flange is further away from the end of the first pipe fitting relative to the external thread portion.

[0009] A nut that mates with the external threaded portion, wherein the first end of the nut is threaded to the external threaded portion of the first pipe fitting, and the second end of the nut is fluid-tightly connected to the second pipe fitting;

[0010] A spring assembly is provided between the nut and the radial flange of the first pipe fitting. The spring assembly is disposed in a compressed state between the nut and the radial flange, such that when the pipe elastic interlock connection mechanism is in the working state, the spring assembly is disposed between the nut and the radial flange with a first compression amount, and when the pipe elastic interlock connection mechanism is in the disassembled state, the spring assembly is disposed between the nut and the radial flange with a second compression amount. The first compression amount is less than the second compression amount, so that when the pipe elastic interlock connection mechanism is in the disassembled state, the nut and the spring assembly are separated, making it easy to remove the nut from the first pipe fitting.

[0011] The pipe elastic interlocking connection mechanism according to the present invention is a connector used in pipeline connections. It employs a spring assembly between the radial flange of a first pipe fitting and the nut of a second pipe fitting. This spring assembly provides a certain elastic pressure to the nut during the operation of the pipe elastic interlocking connection mechanism, preventing the nut from loosening or detaching from the first pipe fitting, thereby maintaining a fluid-tight connection between the first and second pipe fittings. Furthermore, by further compressing the spring assembly, the pressure applied to the nut is reduced, allowing the nut to loosen. This enables the nut to be tightened with a smaller force for disassembly, facilitating the disassembly and subsequent reassembly of the related fluid pipeline. This significantly improves the safety and convenience of pipeline connections, increases the reusability of pipe fittings, and saves on operating costs.

[0012] According to one embodiment of the pipe elastic interlocking connection mechanism of the present invention, the spring assembly includes a spring and a spring compression member disposed between the nut and the spring so as to compress the spring in a direction away from the nut.

[0013] According to another embodiment of the pipe elastic interlocking connection mechanism of the present invention, the spring compression component includes a washer, the outer edge diameter of which is larger than the outer edge diameter of the nut component.

[0014] In another embodiment of the pipe elastic interlocking connection mechanism according to the present invention, the gasket includes a connecting hole disposed on the outer edge of the gasket along the diametrical direction of the gasket, and the pipe elastic interlocking connection mechanism further includes a force-applying component connected to the gasket through the connecting hole, wherein the force-applying component pulls the gasket to compress the spring.

[0015] According to another embodiment of the pipe elastic interlocking connection mechanism of the present invention, the force-applying component includes a handle and a hook, the hook being connected to the connection hole, and the force-applying component is made of metal wire.

[0016] In another embodiment of the pipe elastic interlocking connection mechanism according to the present invention, a rotation limiting structure is provided between the spring compression member and the nut member to limit the relative rotation between the spring compression member and the nut member.

[0017] According to another embodiment of the pipe elastic interlocking connection mechanism of the present invention, the rotation limiting structure includes a convex member disposed on one of the spring compression member and the nut member, and a concave member disposed on the other of the spring compression member and the nut member, the convex member being capable of engaging with the concave member.

[0018] According to another embodiment of the pipe elastic interlocking connection mechanism of the present invention, the rotation limiting structure includes a first wedge tooth disposed on the side of the spring compression member opposite to the nut member, and a second wedge tooth disposed on the side of the nut member opposite to the spring compression member. When the first wedge tooth and the second wedge tooth cooperate, they can restrict the rotation of the nut member relative to the spring compression member.

[0019] According to another embodiment of the pipe elastic interlocking connection mechanism of the present invention, the first wedge tooth includes a first side extending along the axial direction of the spring compression member and a second side extending obliquely within the axial sectional plane of the spring compression member;

[0020] The second wedge-shaped tooth includes a third side extending along the axial direction of the nut and a fourth side extending obliquely within the axial sectional plane of the nut.

[0021] When the nut rotates and abuts against the spring compression member, the first side abuts against the third side, and the second side abuts against the fourth side.

[0022] In another embodiment of the pipe elastic interlocking connection mechanism according to the present invention, the first wedge teeth are arranged in a circular array on the periphery of the side of the spring compression member;

[0023] The second wedge-shaped teeth are arranged in a circular array on the periphery of the side of the nut.

[0024] In another embodiment of the pipe elastic interlocking connection mechanism according to the present invention, the tooth height of the first wedge tooth and the second wedge tooth is set to be greater than 1.5 times the pitch of the external thread portion.

[0025] The present invention also relates to a pipe connection device, which includes any of the pipe elastic interlocking connection mechanisms described above.

[0026] The pipe elastic interlocking connection mechanism according to the present invention is a connector used in pipeline connections. It employs a spring assembly between the radial flange of a first pipe fitting and the nut of a second pipe fitting. This spring assembly provides elastic pressure to the nut during the operation of the pipe elastic interlocking connection mechanism, preventing loosening or detachment of the nut from the first pipe fitting, thereby maintaining a fluid-tight connection between the two fittings. Furthermore, by further compressing the spring assembly, the pressure applied to the nut is reduced, allowing the nut to loosen and enabling it to be tightened with a smaller force for disassembly. This facilitates the disassembly and subsequent reassembly of the related fluid pipeline, significantly improving the safety and convenience of pipeline connections, increasing the reusability of pipe fittings, and saving on operating costs. Whether in industrial production or daily life, the pipe elastic interlocking connection mechanism plays a vital role, providing strong assurance for the stability and reliability of pipeline connections.

[0027] The design structure according to the present invention employs a combination of wedge-shaped teeth and springs, giving it extremely strong anti-loosening capabilities. This anti-loosening characteristic not only ensures that the pipeline connection will not loosen during use, but also allows for easy disassembly and reassembly of the pipeline when needed, thereby greatly improving the safety and convenience of the pipeline connection. This makes this connection mechanism play a crucial role in both industrial and irrigation production. In industrial production, the stability and reliability of pipeline connections are essential for the normal operation of production equipment. The use of the flexible interlocking pipeline connection mechanism provides strong protection for industrial production, ensuring the firmness of the pipeline connection and preventing production accidents or shutdowns due to loosening. In irrigation production, this connection mechanism also plays an important role. For example, in the assembly of irrigation equipment such as valves, pipelines, and irrigation systems, the use of the flexible interlocking pipeline connection mechanism ensures the firmness of the connection, improves safety, reduces the frequency of maintenance and repair, and extends the service life of the irrigation system.

[0028] The flexible interlocking connection mechanism for pipelines according to the present invention not only improves the safety and reliability of pipeline connections, but also brings many conveniences to pipeline control in industrial production and daily life. The design structure of the flexible interlocking connection mechanism makes it a highly efficient connector, fully meeting the stability and reliability requirements of connectors during use. Therefore, the widespread application of the flexible interlocking connection mechanism provides strong protection for the stability and reliability of pipeline connections, and also brings more convenience to people's production and life.

[0038] Reference will now be made in detail to several embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to those skilled in the art that the various described embodiments can be practiced without these specific details. In other instances, well-known methods, processes, components, etc., have not been described in detail to avoid unnecessarily obscuring the details of the embodiments.

[0039] This invention provides a pipe elastic interlocking connection mechanism 10, such as... Figure 1 As shown, the flexible interlocking connection mechanism 10 is used to connect the end of the first pipe fitting 1 and the end of the second pipe fitting 2, thereby connecting the first pipe fitting 1 and the second pipe fitting 2 in fluid communication, so that fluid can flow smoothly between the first pipe fitting 1 and the second pipe fitting 2. The flexible interlocking connection mechanism 10 provides a flexible connection between the first pipe fitting 1 and the second pipe fitting 2, thereby preventing the connection between the first pipe fitting 1 and the second pipe fitting 2 from loosening over time.

[0040] like Figure 1 and Figure 2 As shown, the pipe elastic interlocking connection mechanism 10 according to the present invention includes an external threaded portion 12 disposed at the end of a first pipe fitting 1, a radial flange 14 disposed adjacent to the external threaded portion 12, a nut 16 that mates with the external threaded portion 12, and a spring assembly 18 disposed between the nut 16 and the radial flange 14 of the first pipe fitting 1. Here, the second pipe fitting 2 and the nut 16 can be configured to form a sealing connection. For example, after tightening the external threaded portion 12 on the first pipe fitting 1 and the nut 16, the second pipe fitting 2 naturally seals to the nut 16, while simultaneously forming a fluid-tight connection with the first pipe fitting 1.

[0041] Here, the radial flange 14 protrudes outward from the peripheral wall of the first pipe 1 in the radial direction. That is, the radial flange 14 is an annular structure that extends outward from the outer wall of the first pipe 1 in the radial direction. Compared with the external thread 12, the radial flange 14 is further away from the end of the first pipe 1. That is, the radial flange 14 is closer to the inside of the first pipe 1 in the axial direction of the first pipe 1, while the external thread 12 is located at the outermost end of the first pipe 1.

[0042] The first end of the nut 16 is threaded to the external thread 12 of the first pipe fitting 1, and the second end of the nut 16 is connected to the second pipe fitting 2 in a way that allows for a fluid seal. Here, the fluid seal connection between the nut 16 and the second pipe fitting 2 can be achieved by locking the nut 16 relative to the first pipe fitting 1. For example, a sealing gasket can be provided between the second end of the nut 16 and the second pipe fitting 2. By screwing the nut 16, the first pipe fitting 1 is screwed into the nut 16 from its first end, thereby contacting the end of the second pipe fitting 2. Further screwing of the nut 16 ensures that the external thread 12 and the end of the second pipe fitting 2 are tightly abutted together, thus achieving a fluid seal connection between the first pipe fitting 1 and the second pipe fitting 2. The first pipe fitting 1 and the second pipe fitting 2 can be made of PVC pipe, or other materials such as metal pipes.

[0043] To prevent the nut 16 from loosening from the external thread 12 of the first pipe fitting 1 during pipe use, which would typically lead to fluid leakage, a spring assembly 18 is provided between the nut 16 and the radial flange 14 of the first pipe fitting 1. The spring assembly 18 is positioned in a compressed state between the nut 16 and the radial flange 14, thereby forming an elastic connection between the nut 16 and the radial flange 14. This not only ensures a sealed connection between the nut 16 and the first pipe fitting 1 and the second pipe fitting 2 during use, but also allows for quick disassembly of the nut 16 by compressing the spring assembly 18.

[0044] The spring assembly 18 is configured such that when the pipe elastic interlock connection mechanism 10 is in the working state, the spring assembly 18 is positioned between the nut 16 and the radial flange 14 with a first compression amount, and when the pipe elastic interlock connection mechanism 10 is in the disassembled state, the spring assembly 18 is positioned between the nut 16 and the radial flange 14 with a second compression amount. Here, the first compression amount is less than the second compression amount, so that when the pipe elastic interlock connection mechanism 10 is in the disassembled state, it is easy to remove the nut 16 from the first pipe fitting 1. With this configuration, in the normal operating state, such as when liquid is transported through the pipeline, the spring assembly 18 is compressed by the nut 16 and the radial flange 14, and is compressed between the two with a larger first compression amount. The compression amount of the spring assembly 18 is sufficient to ensure that a certain pressure is applied between the nut 16 and the radial flange 14, thereby ensuring that the nut 16 will not loosen from the external thread 12 of the first pipe fitting 1 due to vibration during normal operation. Furthermore, the spring assembly 18 at the first compression level should also have a certain amount of compression space to further compress the spring assembly 18, thereby causing the nut 16 to disengage from the force applied to it by the radial flange 14. That is, the spring assembly 18 can be in a state of a second compression level with a smaller length, thereby easily performing a rotation operation on the nut 16, thereby separating the second tube 2 from the first tube 1.

[0045] The pipe elastic interlocking connection mechanism 10 according to the present invention can not only apply a certain pressure to the nut 16 through the spring assembly 18 during normal operation to ensure that the nut 16 will not loosen due to vibration, but also release the pressure applied to the nut 16 by compressing the spring assembly 18 when the pipe needs to be disassembled and moved, thereby enabling the nut 16 to be loosened without the use of tools or with simple tools, thereby realizing the disassembly of the first pipe fitting 1 and the second pipe fitting 2 in order to complete the rearrangement of the pipe elastic interlocking connection mechanism 10.

[0046] The spring assembly 18 of the pipe elastic interlocking connection mechanism 10 according to the present invention can be configured to include a spring 182 and a spring compression member 184. The spring compression member 184 is disposed between the nut 16 and the spring 182 so that the spring 182 can be compressed in a direction away from the nut 16. The spring 182 can be compressed by the spring compression member 184, so that the spring 182 and the spring compression member 184 no longer apply pressure to the nut 16, so that the nut 16 can be loosened in a simple way, such as by directly and manually turning the nut 16 to remove the nut 16 from the first pipe fitting 1, thereby separating the first pipe fitting 1 and the second pipe fitting 2, realizing convenient disassembly between the connected pipe fittings.

[0047] Furthermore, the spring compression component 184 may include a washer 1842, such as Figure 3 As shown, a washer made of a material with sufficient hardness can be selected, such as a metal washer. The outer diameter of the washer 1842 can be set to be larger than the outer diameter of the nut 16. This setting facilitates the operation of the nut 16 when the washer 1842 is in contact with the nut 16.

[0048] To facilitate operation of the gasket 1842, the gasket 1842 may include a connecting hole 1844 disposed on the outer edge of the gasket 1842 along the diametrical direction of the gasket 1842. Through the connecting hole 1844, the gasket 1842 can be operated using appropriate tools, such as pulling the gasket 1842 through the connecting hole 1844 to compress the spring 182. Furthermore, the pipe elastic interlocking connection mechanism 10 according to the present invention may also include a force-applying component 186 connected to the gasket 1842 through the connecting hole 1844, which pulls the gasket 1842 to compress the spring 182.

[0049] like Figure 6 As shown, the force-applying component 186 of the pipe elastic interlocking connection mechanism 10 according to the present invention includes a handle portion 1862 and a hook portion 1864, which connects to the connecting hole 1844. Here, the force-applying component 186 can be made of metal wire. Advantageously, in order to apply force evenly to the gasket 1842, a plurality of connecting holes 1844 can be evenly provided in the circumferential direction of the gasket 1842. In the embodiment according to the present invention, two connecting holes 1844 are provided. Thus, the force-applying component 186 can be configured to include two hook portions 1864 to connect to the two connecting holes 1844 located on both sides of the gasket 1842 respectively, so as to apply tension to the gasket 1842, thereby compressing the spring 182.

[0050] To ensure the relative relationship between the gasket 1842, the spring 182, and the radial flange 14 of the first tube 1, a first fixing part is provided on the periphery of the radial flange 14, and a second fixing part is provided on the periphery of the gasket 1842, respectively for fixing both ends of the spring 182. Here, the first fixing part and the second fixing part can be configured as two holes spaced a predetermined distance apart, that is, two holes are formed on the periphery of the radial flange 14 and the gasket 1842 respectively, making them relatively close together, so that a columnar or other suitable-shaped hook suspension part 1846 is formed between the two holes, such as... Figure 3 As shown in the figure. Correspondingly, a first suspension portion 1822 and a second suspension portion 1824 are formed at both ends of the spring 182, respectively, for suspending the radial flange 14 and the washer 1842 of the first tube 1. This allows both ends of the spring 182 to be fixed relative to the radial flange 14 and the washer 1842 of the first tube 1, respectively, while also restricting the rotation of the washer 1842 relative to the radial flange 14.

[0051] like Figure 1 and Figure 2 As shown, the spring 182 is fitted onto the lower part of the external threaded portion 12 of the first tube 1, above the radial flange 14, and tightly abuts against the radial flange 14. The position where the spring 182 is fitted on the first tube 1 can be configured as a smooth rod structure 11, meaning that no external thread is machined at this position. Here, reinforcing ribs 111 can be provided on the smooth rod structure 11 of the first tube 1. The number of reinforcing ribs 111 can be determined according to the diameter of the smooth rod structure 11. For example, if the size of the smooth rod structure 11 is small, two symmetrical reinforcing ribs 111 can be provided along its single diameter direction; if the size of the smooth rod structure 11 is large, more reinforcing ribs 111 can be evenly provided along its outer periphery. Advantageously, four reinforcing ribs 111 can be evenly provided around the outer periphery of the smooth rod structure 11. The reinforcing ribs 111 not only guide and restrict the spring 182 but also provide stability to the spring compression component 184, making the spring compression component 184 more stable during operation.

[0052] According to a preferred embodiment of the pipe elastic interlocking connection mechanism 10 of the present invention, a rotation limiting structure 20 is provided between the spring compression member 184 and the nut member 16 to limit the relative rotation between the spring compression member 184 and the nut member 16. The rotation limiting structure 20 restricts the rotational movement of the nut member 16 by means of the spring compression member 184, thereby preventing relative rotation between the nut member 16 and the external thread portion 12 of the first pipe fitting 1. This prevents the nut member 16 from loosening and failing in operation, thus ensuring the long-term effective operation of the pipeline.

[0053] Furthermore, the rotation limiting structure 20 of the pipe elastic interlocking connection mechanism 10 according to the present invention may include a convex component disposed on one of the spring compression member 184 and the nut member 16, and a concave component disposed on the other of the spring compression member 184 and the nut member 16. The convex component can cooperate with the concave component to limit the relative rotational movement between the two. Here, the shapes of the convex component and the concave component only need to satisfy that they can cooperate with each other to limit the relative movement of the nut member 16 by the spring compression member 184. Their shapes can be square, trapezoidal, semi-circular, elliptical, triangular or other irregular shapes, and their specific shapes are not particularly limited here.

[0054] In a preferred embodiment of the pipe elastic interlocking connection mechanism 10 according to the present invention, as shown in the attached... Figure 1 , 3 As shown in Figure 5, its rotation limiting structure 20 may include a first wedge-shaped tooth 22 disposed on the side of the spring compression member 184 opposite to the nut member 16, and a second wedge-shaped tooth 24 disposed on the side of the nut member 16 opposite to the spring compression member 184. When the first wedge-shaped tooth 22 and the second wedge-shaped tooth 24 are engaged, they can restrict the rotation of the nut member 16 relative to the spring compression member 184. The wedge-shaped teeth can effectively restrict the relative movement between the spring compression member 184 and the nut member 16, and can also disengage the two by rotation in the opposite direction, thereby facilitating the relative rotational movement between the two.

[0055] Specifically, the aforementioned first wedge-shaped tooth 22 can be designed to include a first side surface 222 extending along the axial direction of the spring compression member 184 and a second side surface 224 extending obliquely within the axial tangent plane of the spring compression member 184. That is, the first wedge-shaped tooth 22 can have a roughly right-angled triangular shape, with its right-angled side, i.e., the first side surface 222, aligned with the axial direction of the spring compression member 184, and its hypotenuse, i.e., the second side surface 224, obliquely tangent to the outer peripheral surface of the spring compression member 184, as shown in the attached figure. Figure 1 and attached Figure 3 As shown in the figure. Here, the first wedge-shaped teeth 22 of the right triangle are arranged in a circular array around the circumference of the spring compression member 184 so that the first wedge-shaped teeth 22 are evenly arranged on the circumference of the spring compression member 184.

[0056] Accordingly, the second wedge-shaped tooth 24 can be designed to include a third side 242 extending along the axial direction of the nut 16 and a fourth side 244 extending obliquely within the axial sectional plane of the nut 16, such as... Figure 5As shown. As described above, the first wedge tooth 22 and the second wedge tooth 24 are arranged in a substantially meshing shape, thereby restricting the rotational movement of the nut 16 relative to the first pipe fitting 1 when the first wedge tooth 22 and the second wedge tooth 24 are meshing, thus ensuring the stability of the fluid seal between the first pipe fitting 1 and the second pipe fitting 2. Figure 1 As shown, when the nut 16 rotates and abuts against the spring compression member 184, for example, when the nut 16 is in... Figure 1 Rotating from right to left in the front view, the first side 222 abuts against the third side 242, and the second side 224 abuts against the fourth side 244, causing the first wedge tooth 22 to engage with the second wedge tooth 24, thereby achieving the engagement of the nut 16 and the spring compression member 184. This abutment does not necessarily mean that the two sides are in contact. For example, if the first side 222 and the third side 242 are in contact, the second side 224 and the fourth side 244 may not be in contact, and vice versa. Here, the natural length of the spring 182 is greater than its length when the first wedge tooth 22 and the second wedge tooth 24 are engaged, thus ensuring that the spring 182 is in a compressed state when the first wedge tooth 22 and the second wedge tooth 24 are engaged. The compressibility of spring 182 is greater than the tooth height of the first wedge tooth 22 or the second wedge tooth 24. Therefore, by pulling the spring compression member 184, spring 182 can be compressed by an amount exceeding the tooth height of the wedge teeth, causing the first wedge tooth 22 and the second wedge tooth 24 to disengage and allowing the nut 16 to be tightened. Simultaneously, the tooth height of the first wedge tooth 22 and the second wedge tooth 24 is set to be greater than 1.5 times the pitch of the external thread portion 12 to ensure a sufficiently large meshing force between them.

[0057] When it is necessary to connect pipelines using the pipeline elastic interlocking connection mechanism 10 according to the present invention, the spring 182 and the spring compression member 184 can be successively fitted onto one side of the radial flange 14 of the first pipe fitting 1, with the spring 182 disposed between the radial flange 14 and the spring compression member 184. Then, the nut 16 connected to the second pipe fitting 2 is aligned with the external thread 12 at the end of the first pipe fitting 1, and the nut 16 is tightened from right to left to engage with the external thread 12, thereby achieving a fluid-tight connection between the first pipe fitting 1 and the second pipe fitting 2. If it is necessary to further pre-tighten the nut 16 and the spring compression member 184, the spring 182 can be compressed by using the force application member 186 to pull the compression member 184, while simultaneously further tightening the nut 16, thereby causing the spring 182 to apply greater pressure to the spring compression member 184 and the nut 16, so that the nut 16 has a greater bonding force with the first pipe fitting 1.

[0058] Furthermore, when it is necessary to disassemble the pipeline, the force-applying component 186 can be used to pull the spring compression component 184 to compress the spring 182, so that the spring compression component 184 is separated from the nut component 16. This allows the nut component 16 to be easily turned from left to right by hand, thereby removing the nut component 16 from the external thread portion 12 of the first pipe component 1. This achieves the purpose of separating the first pipe component 1 and the second pipe component 2, so that the relevant pipe components and connecting components can be used to assemble other pipelines.

[0059] The present invention also relates to a pipe connection device, which includes the pipe elastic interlocking connection mechanism 10 as described above. It may include one or more pipe elastic interlocking connection mechanisms 10. For example, a straight fitting for extending the length of a pipe may include one pipe elastic interlocking connection mechanism 10; an elbow for changing the direction of a pipe may include one or two pipe elastic interlocking connection mechanisms 10; and a tee for diverting flow in a pipe may include three pipe elastic interlocking connection mechanisms 10.

[0060] The following is for reference only. Figure 7 The following describes a tee-type flexible interlocking connection device 200 including the pipe flexible interlocking connection mechanism 10 according to the present invention. This tee-type flexible interlocking connection device 200 includes a tee body 201 and three identical pipe flexible interlocking connection mechanisms, namely a first pipe flexible interlocking connection mechanism 210, a second pipe flexible interlocking connection mechanism 220, and a third pipe flexible interlocking connection mechanism 230. These three pipe flexible interlocking connection mechanisms connect three pipe fittings respectively, thereby achieving the function of diverting fluid within the pipeline. Furthermore, in the appendix… Figure 7 In the illustrated embodiment, a pipe connection assembly 250 connected to the third pipe elastic interlocking connection mechanism 230 is also included. The other end of the pipe connection assembly 250 is connected to the pipe 252. The pipe connection assembly 250 may have a structure substantially the same as the pipe elastic interlocking connection mechanism 10, which will not be described in detail here.

[0061] The following is for reference only. Figure 9The following describes a bend elastic interlocking connection device 300 including a pipe elastic interlocking connection mechanism 10 according to the present invention. The bend elastic interlocking connection device 300 includes a bend body 301 and a pipe elastic interlocking connection mechanism 310, which is the pipe elastic interlocking connection mechanism 10 described in this invention. A pipe 312 is connected to the other end of the pipe elastic interlocking connection mechanism 310 opposite to the bend body 301. The bend elastic interlocking connection device 300 allows for the reversal of fluid flow within the pipe. The present invention also relates to pipe elastic interlocking connection devices including multiple pipe elastic interlocking connection mechanisms 10 as described above, which will not be further described here.

[0062] The pipe elastic interlocking connection mechanism according to the present invention is a connector used in pipeline connections. It employs a spring assembly between the radial flange of a first pipe fitting and the nut of a second pipe fitting. This spring assembly provides elastic pressure to the nut during the operation of the pipe elastic interlocking connection mechanism, preventing loosening or detachment of the nut from the first pipe fitting, thereby maintaining a fluid-tight connection between the two fittings. Furthermore, by further compressing the spring assembly, the pressure applied to the nut is reduced, allowing the nut to loosen and enabling it to be tightened with a smaller force for disassembly. This facilitates the disassembly and subsequent reassembly of the related fluid pipeline, significantly improving the safety and convenience of pipeline connections, increasing the reusability of pipe fittings, and saving on operating costs. Whether in industrial production or daily life, the pipe elastic interlocking connection mechanism plays a vital role, providing strong assurance for the stability and reliability of pipeline connections.

[0063] Regarding the embodiments of the present invention, it should also be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other to obtain new embodiments.

[0064] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
