[0002] Water supply steel pipes are steel pipes used to transport water. They are usually made of materials such as carbon steel and stainless steel, and have the characteristics of high strength, good toughness, and corrosion resistance (some materials may be treated with anti-corrosion). The pipes can be combined into a network system by welding, flange connection, grooved connection and other methods. They can withstand a certain water pressure and ensure safe and stable water supply. They are widely used in urban water supply, indoor and outdoor water supply of buildings, industrial water supply and other fields.

[0003] For example, Chinese Patent Publication No. CN218152869U discloses a 3PE anti-corrosion steel pipe for water supply, which includes: a pipe and a connecting flange. The connecting flange is inserted and installed at one end of the pipe. Four sets of fixing blocks are fixedly connected to the inner end of the connecting flange. A movable column is connected through the inside of the fixing block. A rotating block is connected to one end of the movable column through the fixing block. A pressure block is movably connected to the surface of the rotating block. The surface of the pressure block is pressed against the inner wall of the pipe.

[0004] During the operation of a water supply pipeline system, when encountering conditions such as slight foundation settlement or lateral displacement due to environmental factors, the connections of traditional steel pipes used for water supply are prone to loosening. This loosening not only damages the integrity of the pipeline structure but also directly affects the sealing performance of the water supply pipeline system, potentially leading to water leakage, water pressure loss, and other problems, thereby threatening the safe and stable operation of the entire water supply system and the reliability of water supply. Utility Model Content

[0008] Preferably, the inner side of the second adjusting ring, away from the one end of the first adjusting ring, is fixedly connected with a limiting block ring, and the inner side of the second adjusting ring, close to the one end of the first adjusting ring, is fixedly connected with a sliding ring.

[0009] Preferably, the outer side of the first adjusting ring is fixedly connected with a plurality of sliding blocks at equal intervals in the circumferential direction, the sliding ring is provided with a plurality of sliding grooves at positions corresponding to the sliding blocks, and the sliding blocks are slidably inserted into the sliding grooves.

[0010] Preferably, the two sides of the plurality of sliding blocks are respectively fixedly connected with limiting blocks.

[0014] Preferably, the end face of the first adjusting ring, away from the second adjusting ring, is fixedly connected with a sealing ring.

[0015] Compared with the prior art, the vertical telescopic adjusting assembly has the advantages and positive effects that:

[0016] 1、In the utility model, through the cooperation of the vertical telescopic adjusting assembly and the flexible hose, the stress generated by pipeline vibration can be dispersed and absorbed, structural damage caused by stress concentration to the pipeline connection can be avoided, and the anti-vibration performance and durability of the pipeline system are greatly improved; in addition, the self-adaptive adjusting mechanism can effectively maintain the sealing performance of the pipeline system, even under complex vibration working conditions, water leakage caused by loose interface can be prevented, and the continuity and safety of water supply transportation are ensured.

[0017] 2. In this invention, when the vertical telescopic adjustment assembly performs vertical telescopic adjustment, the adapter drives the second adjustment ring to slide along the side of the first adjustment ring.

At the same time, the flexible hose 33, with its good flexibility, will undergo elastic deformation in the horizontal direction, effectively offsetting the offset caused by the left and right sliding of the pipe. The synergistic effect of the vertical telescopic adjustment component 32 and the flexible hose 33 can disperse and absorb the stress generated by the pipe vibration, avoiding stress concentration and structural damage to the pipe connection, and greatly improving the vibration resistance and durability of the pipeline system. In addition, this adaptive adjustment mechanism can effectively maintain the sealing of the pipeline system, and even under complex vibration conditions, it can prevent water leakage caused by loose joints, ensuring the continuity and safety of water supply.
