Pipeline temperature sensor convenient to install

The utility model relates to the technical field of sensors, and discloses a pipeline temperature sensor convenient to install, which comprises a sensor body, the bottom end of the sensor body is fixedly connected with a detection rod, the middle part of the outer surface of the detection rod is fixedly sleeved with a square block, and the outer surface of the square block is movably sleeved with an installation frame. And the mounting frame is fixedly connected to the surface of the pipeline. By arranging the spring, the disc, the vertical rod, the limiting rod and the frame, the limiting rod can be driven to move downwards and compress the spring by pressing the vertical rod downwards, when the limiting rod is separated from the interior of the square groove, a worker can rotate the vertical rod to enable the limiting rod to move out of the interior of the frame, and therefore the limiting effect on the square block can be relieved; and the sensor body, the detection rod and the square block can be disassem
