1results about How to "Wipe clean" patented technology

The utility model discloses an ultrasonic flaw detector relates to ultrasonic flaw detector technical field, the utility model discloses a shell, the shell inner wall fixedly connected with the inner shell, the inner shell inner wall slidingly connected with the probe, the probe top fixedly connected with the spring, the spring top and inner shell bottom fixedly connected, the inner shell inner wall threadedly connected with the threaded rod. The utility model discloses a threaded rod is set up, when the shell is pressed down, the probe will move upwards, and the spring is extruded, and the bottom of threaded rod is contacted simultaneously, in the process of the probe going up, the coupling agent in the storage groove will flow out through the gap between the shell and the probe to be daubed, can prevent because the strength of pressing is too big, causes the outflow of coupling agent too much to cause waste, and the threaded rod is turned to the bottom to lock the probe, makes it when the probe bottom is wiped, the probe will not move, makes it wipe more clean.
