The utility model provides a pipe clamp, include that the bottom is equipped with the lower pipe clamp of pipe clamp fixed part, connecting portion and the continuous last pipe clamp of lower pipe clamp are passed through to one end, and the other end of going up pipe clamp can be because of upset and the lower pipe clamp looks joint of last pipe clamp around connecting portion to pipe clamp is the lock form with lower pipe clamp on the messenger, still include formed at under and the double -layered hole between the pipe clamp of the last pipe clamp that is lock form to and in connecting portion one sides, last pipe clamp with be equipped with the upset around connecting portion because of last pipe clamp down between the pipe clamp, and make upward the continuous safety mechanism of joint between pipe clamp and the lower pipe clamp. A pipe clamp, make the last pipe clamp that links to each other by connecting portion and pipe clamp's other end looks joint down, the accessible presss from both sides the pore pair pipeline, and to carry out the mounting board fixed, and the setting through safety mechanism, at connecting portion during because of repetitious usage or pipeline shake breaking occur, can guarantee that the connection between pipe clamp and the lower pipe clamp is not broken off to can keep fixed to the pipeline, and have better result of use.
