[0031] Among them, the first half pipe 41 and the second half pipe 42 are detachably connected through the connecting piece 43, and the inner walls of the first half pipe 41 and the second half pipe 42 are each provided with an elastic protective layer 44; through the connecting piece 43, the connection of the first half pipe 41 and the second half pipe 42 is realized, and a certain strength and stability are possessed to ensure that the protective sleeve 4 will not easily separate the connecting piece 43 during use, including but not limited to bolt and nut assemblies, clamps, buckles and the like; the protective layer 44 is made of rubber material, when external impact force acts on the protective sleeve 4, the elastic protective layer 44 will elastically deform to absorb and disperse the impact force, thereby effectively reducing the risk of damage to the interface due to external impact and improving the mechanical protection capability of the protective structure to the interface to ensure the long-term stable operation of the pipeline system; at the same time, the elastic protective layer 44 can prevent scratching and other damage to the surface of the copper straight pipe during assembly or position adjustment to ensure the surface integrity of the copper pipe; in addition, the elastic protective layer 44 has a certain flexibility and adaptability, when the pipeline expands and contracts due to temperature changes, the contact between the protective sleeve 4 and the pipeline can adapt to such size changes through the deformation of the elastic protective layer 44, which not only ensures the close fit between the protective sleeve 4 and the pipeline, but also prevents the interface from being damaged due to stress caused by thermal expansion and contraction, so that the protective structure can stably function under different temperature and other complex working conditions.

[0032] Preferably, the inner side of the first half pipe 41 and the second half pipe 42 is provided with a positioning protrusion 45, and the outer side wall of the first pipe fitting 1 and the second pipe fitting 2 is provided with a positioning groove 5 corresponding to the position of the positioning protrusion 45, and the positioning protrusion 45 is inserted and matched with the corresponding positioning groove 5; when installing the protective sleeve 4, the positioning protrusion 45 on the inner side of the first half pipe 41 and the second half pipe 42 is aligned with the positioning groove 5 on the corresponding position of the outer side wall of the first pipe fitting 1 and the second pipe fitting 2, and then the insertion is carried out, the shape and size of the positioning protrusion 45 and the positioning groove 5 are matched with each other, so that they can be tightly fitted, this design utilizes the complementarity of the physical structure, limits the relative displacement between the protective sleeve 4 and the pipe fitting in the circumferential and axial directions, so as to realize the accurate positioning and stable installation of the protective sleeve 4 at the pipe fitting interface, and further reduce the risk of interface protection failure caused by the displacement of the protective sleeve 4, and enhance the stability and reliability of the entire connection part.

[0033] Preferably, the outer side wall of the sealing rubber ring 31 is in a wave shape structure, and the wave trough of the wave shape structure abuts against the top surface of the sealing gasket plate 32; since the sealing rubber ring 31 has elasticity, it is extruded during the insertion process, and the wave shape structure will be elastically deformed; the wave trough abuts against the top surface of the sealing gasket plate 32 tightly, while the wave crest expands to both sides under the action of pressure, filling more irregular gaps between the spigot 11 and the socket 21, compared with the sealing mode of plane contact, the wave shape structure increases the contact points and contact area between the sealing rubber ring 31 and the sealing gasket plate 32, and further enhances the plugging ability of the fluid leakage path by utilizing the deformation of the wave crest and the wave trough.

[0034] Preferably, the top surface of the sealing gasket plate 32 is provided with a containing groove 322 matched with the outer side wall of the sealing rubber ring 31, and the sealing rubber ring 31 is partially embedded in the containing groove 322; this design plays a role in positioning and fixing the sealing rubber ring 31, preventing it from being displaced or deformed during use, and the sealing rubber ring 31 can still remain in the correct position and maintain a good sealing state when the pipeline is affected by factors such as vibration, impact or temperature change, which helps to improve the stability and service life of the entire interface protection structure, and reduce the maintenance and replacement cost caused by sealing failure.

[0036] Preferably, the two ends of the protective sleeve 4 are provided with necked-in structures 47, the inner and outer diameters of which gradually increase towards the middle part of the protective sleeve 4; through this design, the two ends of the protective sleeve 4 form a smooth transition, eliminating the edges of the original straight edge and improving the safety of operation.

[0037] Preferably, the side walls of the first half pipe 41 and the second half pipe 42 are provided with anti-skid lines 48; through this design, the roughness between the inner side walls of the first half pipe 41 and the second half pipe 42 and the surface of the protected pipe is increased, according to the principle of friction, when two objects contact, the greater the surface roughness, the greater the friction between them, when the pipe is placed in the protective sleeve 4 composed of the first half pipe 41 and the second half pipe 42, the anti-skid lines 48 can effectively prevent the pipe from sliding in the protective sleeve 4, further ensuring that the pipe remains in a stable position in the protective sleeve 4.

In the pipeline system operation process, if external collision, extrusion and other external force are acted, the elastic protective layer 44 of protective sleeve 4 occurs elastic deformation, absorbs and disperses impact force, avoids that interface part directly bears excessive external force, and the multiple reinforcing ribs 46 on the inner side wall of protective sleeve 4 are also dispersed to the whole protective sleeve 4 structure, avoid that partial stress is too large and leads to deformation or damage, inhibit the deformation of protective sleeve 4 in the axial direction, simultaneously, if pipeline produces thermal expansion and cold shrinkage due to temperature change, the deformation of elastic protective layer 44 can adapt to the size change, guarantee the close fit between protective sleeve 4 and pipeline, when needing to check, maintain or replace sealing assembly 3 of interface, connecting piece 43 is dismantled, and first half pipe 41 and second half pipe 42 are separated, so that the interface part can be conveniently operated.
