The utility model relates to an antidetonation water pipe bearing structure, including a horizontal pole, locate the horizontal pole both ends and link wall connection, with the U -shaped pipe strap that the horizontal pole is connected, the U -shaped pipe strap includes outer pipe strap of being connected with the horizontal pole and the interior pipe strap of being connected with outer pipe strap, interior pipe strap is made by elastic material, outer pipe strap and interior pipe strap all are the U -shaped, the water pipe is taken and is put in interior pipe strap, outer pipe strap and spring coupling is crossed to the inner tube cartoon. According to the technical solution of the mounting transition disc of the speed reducer, spring coupling is crossed with the outer tube cartoon to interior pipe strap, the water pipe is taken and is put in interior pipe strap, the water pipe is because of taking place to push interior pipe strap when expend with heat and contract with cold produces volume change, and pass through spring coupling between interior pipe strap and the outer pipe strap, its volume change that can contain the water pipe betterly, after the water pipe returns to normal, interior pipe strap can still be laminated with the water pipe outer wall under the effect of spring restoring force, thereby produce the clearance in avoiding between pipe strap and the water pipe outer wall, the phenomenon that the water pipe rocked takes place.
