Technical Field

[0001] The utility model relates to the technical field of thickness detection, in particular to a device for detecting the thickness of an insulation layer used for preparing an insulation pipe. Background Art

[0002] The ultrasonic thickness gauge measures thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe. The thickness of the material to be measured is determined by accurately measuring the time it takes for the ultrasonic wave to propagate in the material. It is suitable for the thickness detection of the insulation layer prepared by the insulation pipe.

[0003] For example, the Chinese authorized patent with announcement number CN208795194U (an ultrasonic thickness gauge) includes an ultrasonic thickness gauge main unit, a connecting line, a probe, a handle, a protective shell, a stepped plate, a circular plate and circular sandpaper. The handle is welded to the right end of the ultrasonic thickness gauge main unit, and a probe is provided on the upper end of the handle. The connecting line is fixed to the right end of the probe, and the connecting line is installed on the upper end of the ultrasonic thickness gauge main unit. The ultrasonic thickness gauge main unit is connected to the probe through the connecting line. The protective shell is fixed at the rear end of the ultrasonic thickness gauge main unit, and the stepped plate is fixed at the left end of the protective shell.

Especially in hot weather, it is also easy to cause internal damage to the ultrasonic thickness gauge, resulting in poor holding comfort and single function. Therefore, it does not meet the existing needs. In this regard, we propose an insulation layer thickness detection device for the preparation of insulation pipes. Utility Model Content
