Description

Technical Field

[0001] This utility model relates to the field of corrugated pipes, and more particularly to a polyolefin-reinforced MPVE corrugated pipe structure. Background Technology

[0002] A corrugated pipe is a flexible pipe with wavy (corrugated) folds, typically made of metal (such as stainless steel) or plastic. Its corrugated structure gives it excellent flexibility, absorbing vibration, compensating for displacement, and adapting to thermal expansion and contraction or mechanical movement. It is widely used in pipe connections, automotive exhaust systems, industrial equipment, and building water supply and drainage systems, serving to reduce vibration, noise, seal, and extend pipeline life. Some corrugated pipes also possess high-pressure resistance and corrosion resistance, making them suitable for complex working conditions.

[0003] While existing technologies can achieve certain performance characteristics of corrugated pipes in general use, they suffer from drawbacks such as low connection efficiency and susceptibility to damage at bends. To address these issues, we propose a polyolefin-reinforced MPVE corrugated pipe structure that solves these problems. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a polyolefin-reinforced MPVE corrugated pipe structure.

[0005] The technical solution of this utility model is as follows: a polyolefin reinforced MPVE corrugated pipe structure, including a pipe body, a protective ring and a rotating disk, characterized in that: a flange one and a flange two are provided on both sides of the pipe body, a rotating disk is rotatably mounted on the surface of the flange one, buckles with elastic structures are provided on both sides of the surface of the rotating disk, and a protective ring is provided on the surface of the pipe body. When using this device, flange two with positioning holes can be installed on the upper end of the output device. Then, flange one with a buckle on the other end can be connected to another pipe with buckles on both sides. During connection, it can be fixed as long as the buckle on one side of the pipe engages with the limiting groove on the other side of the pipe (adding a sealing ring can effectively seal the pipe). The pipe is often subjected to greater impact force at the bend. The protective ring can be manually moved to the bend to increase the stress on the bend and increase the service life of the device. In addition, the reinforcing ring can increase the rigidity of the pipe. Overall, this device has the functions of local protection and quick connection, and has high practicality.

[0006] Preferably, the second flange has positioning holes arranged in a ring array on its surface. The ring array design of the positioning holes facilitates the precise docking of the second flange with external equipment, ensuring stability and sealing during installation and reducing the risk of misalignment.

[0007] Preferably, the rotating disk has limit grooves on both sides, and the buckle surface is provided with barbs that fit into the limit grooves. The cooperation between the limit grooves and the barbs enables the buckle to be firmly locked, preventing loosening after connection and improving the reliability of the structure.

[0008] Preferably, the rotating disk has a guide rail on its surface, and the buckle is inserted into the guide rail. The guide rail structure allows the buckle to move along a fixed path, ensuring the smoothness and stability of the fastening process and preventing the buckle from shifting or jamming.

[0009] Preferably, a spring is fixed between one side of the buckle and the inside of the guide rail. The spring provides elastic support, enabling the buckle to automatically reset, facilitating quick assembly and disassembly, and enhancing the tightness of the connection.

[0010] Preferably, the surface of the pipe body is provided with reinforcing rings arranged in a linear array. The reinforcing rings enhance the overall rigidity and bending resistance of the pipe body, making it suitable for high-pressure or high-load conditions and extending its service life.

[0011] Preferably, the two sides of the protective ring are fixed together by connecting wires. The protective ring is elastic and can be flexibly adjusted to protect vulnerable parts. The connecting wires ensure that the protective ring is stable and does not fall off, thereby improving local impact resistance.

[0012] Compared with existing technologies, the advantages of this utility model are: This invention achieves rapid connection and fixation of pipe bodies through the cooperative design of a flange and a rotating disc. Specifically, the elastic buckle and the locking structure of the limiting groove on the rotating disc allow for pipe body connection without complex tools; installation can be completed simply by aligning and pressing, significantly improving assembly efficiency. Simultaneously, the barbed design of the buckle and the elastic support of the spring ensure the stability of the connection, avoiding the problem of loosening that occurs with traditional bolt fixings. Furthermore, the movable design of the protective ring allows for localized reinforcement of bending areas, effectively dispersing impact force and significantly extending the service life of the pipe body.

[0013] Based on the first beneficial effect, this utility model further optimizes the overall structure of the pipe body. The linear array distribution of the reinforcing rings enhances the axial stiffness of the pipe body, making it less prone to deformation under high pressure or external loads. The protective ring is made of elastic material and fixed by connecting wires, ensuring both the flexibility of protection and the integrity of the structure. In addition, the positioning hole design on the flange facilitates precise docking with the output device, reducing installation errors. Overall, this utility model combines efficient connection, local protection, and structural reinforcement, making it suitable for various complex working conditions and possessing high practicality and economy.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The pipe body 1 is provided with a flange 1 5 and a flange 2 8 on both sides. The rotating disk 6 is rotatably mounted on the surface of the flange 1 5. The rotating disk 6 is provided with buckles 11 with elastic structures on both sides of the surface of the rotating disk 6. The protective ring 4 is movably mounted on the surface of the pipe body 1. When using this device, flange 28 with positioning hole 2 can be installed on the upper end of the output device, and flange 5 with buckle 11 on the other end can be connected to another pipe 1 with buckles 11 on both sides. When connecting, it is only necessary to fasten the buckle 11 of one side of the pipe 1 with the limiting groove 12 of the other side of the pipe 1 to achieve fixation (adding a sealing ring can effectively seal). The bending part of the pipe 1 is often subjected to a large impact force. The protective ring 4 can be manually moved to the bending part so that the protective ring 4 can increase the stress strength of the bending part and increase the service life of the device. In addition, the reinforcing ring 3 can increase the rigidity of the pipe 1. This device has the functions of local protection and quick connection, and has high practicality.

[0023] Example 2 Please see Figures 1-4 As shown, this embodiment further includes, based on embodiment 1, a positioning hole 2 arranged in a ring array on the surface of flange 2 8.

[0025] The rotating disk 6 has a guide rail 10 on its surface, and the buckle 11 is inserted into the guide rail 10. The structure of the guide rail 10 allows the buckle 11 to move along a fixed path, ensuring the smoothness and stability of the fastening process and preventing the buckle 11 from shifting or getting stuck.

[0026] A spring 9 is fixed between one side of the buckle 11 and the inside of the guide rail 10. The spring 9 provides elastic support, enabling the buckle 11 to automatically reset, facilitating quick disassembly and assembly, and enhancing the tightness of the connection.

[0027] The surface of the tube body 1 is provided with reinforcing rings 3 arranged in a linear array. The reinforcing rings 3 enhance the overall rigidity and bending resistance of the tube body 1, making it suitable for high-pressure or high-load conditions and extending its service life.

[0028] The protective ring 4 is fixed between the two sides by the connecting wire 7. The protective ring 4 is elastic and can be flexibly adjusted to protect vulnerable parts.
