Mounting clamp of ultrasonic sensor

The invention provides a mounting clamp of an ultrasonic sensor. The mounting clamp comprises a mounting plate, positioning blocks which are arranged at the central line positions of the two ends of the mounting plate, bracket rails which are respectively arranged on four symmetrical mounting plate rails of the mounting plate, buckles which are respectively arranged on slide ways of the bracket rails and can adjust the height, a scale slide strip with two ends which are respectively fixed on the buckles, and a sensor bracket which is arranged on the scale slide strip and is used for mounting the ultrasonic sensor. The mounting clamp of the ultrasonic sensor disclosed by the invention is simple in structure and convenient to use; an ultrasonic sensor probe can be effectively mounted according to straight pipe sections with different apertures and accurate positions of clamping the ultrasonic sensor probe on the straight pipe sections can be guaranteed; and a mounting distance between the sensors can be visually read and the mounting distance between the sensors can also be adjusted according to requirements.
