[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0014] like Figure 1-3 As shown, a water supply pipeline connection structure suitable for complex terrain includes a connecting flange 1. A boss 2 is integrally formed on the inner end of the connecting flange 1. A connecting pipe 3 is welded in the middle of the boss 2. A transmission recess 4 and a groove 5 are provided on the connecting pipe 3. The transmission recess 4 is opened at the outer end of the connecting pipe 3, and an external thread 6 is opened on the outer side of the transmission recess 4. The groove 5 is symmetrically opened at the inner end of the connecting pipe 3. An adjusting nut 7, a transmission sleeve 8, and a tensioning ring 9 are provided on the transmission recess 4. The adjusting nut 7 is fitted on the outer end of the transmission recess 4 and is threadedly connected to the external thread 6. The transmission sleeve 8 is fitted on the middle section of the transmission recess 4. The tensioning ring 9 is fitted on the inner end of the transmission recess 4. A sealing ring 10 is fitted on the groove 5. The connecting flange 1, the connecting pipe 3, the adjusting nut 7, the transmission sleeve 8, and the tensioning ring 9 are all made of brass.
[0015] Specific usage: When connecting water pipes, insert the connecting pipe 3 into the water pipe joint end. At this time, the sealing ring 10 is driven into the water pipe by the connecting pipe 3, sealing the inner wall of the water pipe and the connecting pipe 3. Then, tighten the adjusting nut 7 to rotate and move it along the external thread 6 towards the inner end of the water pipe. The rotation and movement of the adjusting nut 7 pushes the transmission sleeve 8. After the transmission sleeve 8 is pushed, it squeezes the tension ring 9. After the tension ring 9 is squeezed, it expands outward and squeezes the inner wall of the water pipe. At this time, the connecting pipe 3 is firmly fixed to the water pipe joint end. Finally, connect the connecting flanges 1 of the opposite water pipe joint ends together with bolts.
[0016] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
