Concrete ultrasonic detector for building engineering quality supervision

The invention relates to the technical field of ultrasonic detectors and discloses a concrete ultrasonic detector for building engineering quality supervision. The detector comprises a machine body. The top of the body is slidably connected with a top cover through a connecting shaft; Protective pads are installed around the outsides of the body and the top cover. Transparent glass is fixedly connected inside the top cover. The bottom of the front side of the connecting shaft is provided with a vertical groove and the inside of the vertical groove is provided with a limiting device, and the bottom of the limiting device is fixedly connected with a pulling cap. According to the concrete ultrasonic detector, on the basis of clamping of the limiting device and the display screen, the concreteultrasonic detector is opened by using the pulling cap; and the protective pads are installed around the outsides of the body and the top cover and have suitable thickness and elasticity to prevent damages to the concrete ul
