Pipeline fixing mechanism

The utility model relates to the technical field of pipeline fixing and discloses a pipeline fixing mechanism. The pipeline fixing mechanism comprises a support, a cam and an adaptive bloc, wherein a pipeline fixing part is arranged on the support, and a first cam groove with the covering angle being larger than 180 degrees is also arranged. The cam comprises a locking part, a first camshaft is arranged at the bottom end of the locking part, a second camshaft is arranged at the top end of the locking part, and the first camshaft is installed in the first cam groove in a rotary mode. A second cam groove with the covering angle larger than 180 degrees is formed in the adaptive block, the adaptive block is installed on the second camshaft in a rotary mode, and a clamping space is formed by the top end face of the adaptive block and one side of the support. A bolt sequentially penetrates through the support and the locking part and locks the support and the cam in cooperation with a nut. According to the pipeline fixing mechanism, a pipeline can be fixed to adjacent parts around the pipeline, the pipeline fixing mechanism can be highly adapted to the shapes of the parts where the pipeline is fixed, the pipeline fixing space is widened, arrangement is facilitated, assembly is easy, and using is convenient.
