All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b): referring to fig. 1-2, a direct-insert stainless steel corrugated pipe includes a pipe body 1, a bolt body 2 is formed at two ends of the pipe body 1, a connector 3 is sleeved on an outer thread of the bolt body 2, a sealing plate 31 is fixedly arranged at an inner side of the connector 3, the sealing plate 31 and the connector 3 are integrally formed, an extending body 4 is arranged at one end of the connector 3 far away from the pipe body 1 in a penetrating manner, one end of the extending body 4 located inside the connector 3 penetrates through the sealing plate 31, and the extending body 4 and the sealing plate 31 are elastically connected; the extension body 4 is telescopically mounted on the connection head 3, wherein the extension body 4 is used for inserting into a corresponding position on the water purifier or the pressure barrel.

Referring to fig. 2, a fixing ring 32 and a return spring 33 are sleeved on an outer side of a section of the extension body 4 located inside the connector 3, the fixing ring 32 is fixedly connected with the extension body 4, the fixing ring and the extension body are welded and fixed, and two ends of the return spring 33 are respectively attached to the sealing plate 31 and the fixing ring 32; in a natural state, the return spring 33 is in a compressed state, i.e. a section of the extension body 4 is always located outside the connector 3 without being affected by an external force. The upper side and the lower side of the connector 3 are respectively provided with a sliding opening 34 along the length direction of the connector 3 in a penetrating manner, two pulling parts 35 are fixedly arranged on the fixing ring 32, and the two pulling parts 35 respectively penetrate through the two sliding openings 34; therefore, the user can pull the extension body 4 backward through the pulling portion 35 to be retracted inside the connection head 3. A first sealing ring 36 is arranged on one surface of the sealing plate 31, which faces the bolt body 2, and the first sealing ring 36 is tightly attached to the bolt body 2; a round hole for the extension body 4 to pass through is formed in the sealing plate 31 in a penetrating manner, and a second sealing ring 37 is attached to the inner wall of the round hole; first sealing washer 36 and second sealing washer 37 are rubber material, and first sealing washer 36 splices on closing plate 31, and second sealing washer 37 splices at the round hole inner wall, and the effect improves the leakproofness of connector 3, prevents that the inside liquid of body 1 from leaking.

Referring to fig. 1, a shockproof sheath 5 is sleeved on the outer side of the pipe body 1, the shockproof sheath 5 includes an upper shell 51 and a lower shell 52, forming portions 53 are respectively disposed on two outer sides of the upper shell 51 and the lower shell 52, the forming portions 53 and the shockproof sheath 5 are integrally formed, and a connecting portion 57 convenient for installation is fixedly disposed on the bottom side of the lower shell 52.
