The conventional way to connect pipes is to overlap the axes of the pipes to be connected, and then use flanges, threaded sleeves and other connectors to connect them. However, some pipes break during use, and the axes of the pipes at the broken position are staggered, while there are no flanges, threaded sleeves and other connectors at the broken position.

[0015] Reference Figure 1 、 2 、3, and 4, the implementation process of the connecting pipe is described in detail as follows:

[0016] A pipe connection structure includes two rubber sleeves 11 that can be coupled to the outer wall of the pipe. The two rubber sleeves 11 can be coupled together to form a complete ring, which can protect the two butt-jointed pipes and can also form a seal after being compressed by force. The two rubber sleeves 11 are respectively fixedly connected to two semi-circular blocks 12 with threads processed on their outer walls. The two semi-circular blocks 12 are made of metal materials. When the two semi-circular blocks 12 are coupled together, they can squeeze the two rubber sleeves 11 in the middle, so that the rubber sleeves 11 are tightly attached to the outer wall of the pipe, fully sealing the connection of the pipe and preventing the fluid in the pipe from leaking. Threads are processed on the outer walls of the two semi-circular blocks 12, and the threads on the outer walls of the two semi-circular blocks 12 can be combined into a complete thread. Two pressing pipes 13 that can be coupled are threadedly connected to the outer walls of the two semi-circular blocks 12. Two ear plates 14 are fixedly connected to both of the two pressing pipes 13. The corresponding ear plates 14 are detachably connected by multiple pairs of matching connectors 17. The two pairs of ear plates 14 are fixedly connected and disassembled by multiple pairs of connectors 17. When the two pairs of ear plates 14 are connected, the threads on the inner walls of the two pressing pipes 13 are combined into a complete thread and can be fully screwed and connected with the threads on the outer walls of the two semi-circular blocks 12. The two pressing pipes 13 apply pressure to the two semi-circular blocks 12 under the pressure of the fastening of the two pairs of ear plates 14, thereby applying pressure to the two rubber sleeves 11, ensuring that the two rubber sleeves 11 are fully deformed, ensuring the sealing performance of the two rubber sleeves 11 at the pipe connection. At the same time, the two pressing pipes 13 can be rotated to ensure that the coupling parts of the two pressing pipes 13 are staggered from the coupling parts of the two semi-circular blocks 12, preventing fluid from seeping or leaking when the two rubber sleeves 11 age, and further preventing the leaked fluid from flowing out through the coupling parts of the two semi-circular blocks 12 and the coupling parts of the two pressing pipes 13. The coupling of the two semi-circular blocks 12 and the coupling fixation of the two pressing pipes 13 can correct the two misaligned connected pipes, ensuring the stable butt-joint and connection of the two pipes. When rotating the two pressing pipes 13, the two pairs of ear plates 14 can be rotated to increase the convenience of rotating the two pressing pipes 13.

[0017] Combined with the above embodiments, the following functions can also be achieved;

[0018] Reference Figure 2 , the implementation process of increasing the friction force between the two rubber sleeves 11 and the contacted pipe is described in detail:

[0019] On the inner walls of the two rubber sleeves 11, a plurality of bumps 16 for increasing friction are formed. When the plurality of bumps are stressed, their deformation increases the friction between the two rubber sleeves 11 and the contacted pipeline, thereby preventing the two rubber sleeves 11 from separating from the contacted pipeline and affecting the sealing of the connected pipeline by the two rubber sleeves 11.

[0020] Combined with the above embodiments, the following functions can also be achieved;

[0021] Refer to Figure 2 , and the implementation process of the shape stress deformation of the bumps 16 for increasing friction is described in detail:

[0022] The plurality of bumps 16 are spherical, so that they can be fully deformed when stressed. The spherical bumps 16 are squeezed into a disc shape, thereby increasing the friction between the two rubber sleeves 11 and the contacted pipeline, and thus fully sealing the connected pipeline.

[0023] Combined with the above embodiments, the following functions can also be achieved;

[0024] Refer to Figure 2 , and the implementation process of the shape stress deformation of the bumps 16 for increasing friction is described in detail:

[0025] The plurality of bumps 16 are strip-shaped. After the two pressing pipes 13 press the two semi-circular blocks 12 and then press the two rubber sleeves 11, causing the bumps 16 on the two rubber sleeves 11 to deform, when the two pressing pipes 13 are rotated, the linear strip-shaped bumps 16 are twisted along the rotation direction of the two pressing pipes 13, which can greatly increase the friction between the two rubber sleeves 11 and the pipeline. At the same time, it can also enhance the sealing performance of the two rubber sleeves 11 to the connected pipeline and fully prevent fluid leakage.

[0026] Combined with the above embodiments, the following functions can also be achieved;

[0027] Refer to Figure 4 , and the implementation process of connecting multiple pairs of ear plates 14 is described in detail:

[0028] The connecting piece 17 is a standard bolt and nut, which can enhance the convenience of replacing the multiple connecting pieces 17.

[0029] Combined with the above embodiments, the following functions can also be achieved;

[0030] Refer to Figure 4 , and the implementation process of preventing the multiple pairs of ear plates 14 from being worn when disassembling and assembling the connecting piece 17 is described in detail:

[0031] The bolt and nut are used in cooperation with gaskets when in use, so as to avoid the bolt and nut directly contacting the multiple pairs of ear plates 14, causing wear of the multiple pairs of ear plates 14 and affecting the subsequent use of the ear plates 14.

[0032] Combined with the above embodiments, the following functions can also be achieved;

[0033] Referring to Figure 3 , the implementation process of facilitating the rotation of the two pressing tubes 13 driven by the force on the two pairs of ear plates 14 will be described in detail:

[0034] Long grooves 15 are machined on multiple said ear plates 14, so that ropes can be tied in the long grooves 15 of the two pairs of ear plates 14. The ropes are wound around the outer walls of the two pressing tubes 13 for a quarter of a circle, and pulled forcefully to realize the rotation of the two pressing tubes 13, the dislocation of the coupling parts of the two pressing tubes 13 and the coupling parts of the two semi-arc blocks 12, and the disassembly and assembly of the two pressing tubes 13 and the two semi-arc blocks 12 can also be realized.

[0035] Combined with the above embodiments, the following functions can also be achieved;

[0036] Referring to Figure 3 , the implementation process of increasing the pressing of the two pressing tubes 13 on the two semi-arc blocks 12 will be described in detail:

[0037] Buffer blocks are fixedly connected to multiple said ear plates 14. When the opposite ear plates 14 are tightly connected, multiple corresponding ear plates 14 are fixed by multiple connecting pieces 17. The corresponding ear plates 14 compress the corresponding buffer blocks to ensure that the two pressing tubes 13 undergo slight deformation to press and fix the two semi-arc blocks 12. Multiple said buffer blocks are made of flexible materials and can undergo large deformation to ensure that the two pairs of ear plates 14 drive the two pressing tubes 13 to undergo slight deformation.
