Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic thickness gauges, in particular to an ultrasonic thickness gauge with a probe that is convenient to replace. Background Art

[0002] An ultrasonic thickness gauge is a device used to measure the thickness of objects. It measures thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object being measured and reaches the material interface, the pulse is reflected back to the probe, and the thickness of the material being measured is determined by accurately measuring the time it takes the ultrasonic wave to propagate in the material. An ultrasonic thickness gauge mainly consists of two parts: a host and a probe.

[0003] For example, the authorization announcement number "CN220729196U" is named an ultrasonic thickness gauge that is easy to replace the probe. The restriction of the clamping head on the connecting rod is released. By pulling the connecting rod outward, the male plug can be separated from the female socket, which is convenient for disassembly and assembly of the probe. The design is simple, which is not only easy to operate, but also reduces the difficulty of processing and production cost. However, the existing ultrasonic thickness gauge that is easy to replace the probe can complete the pulling and replacement of the probe by pressing the clamping rod on both sides. However, in actual use, the clamping rods on both sides are completely exposed to the outside. When the operator accidentally touches it during use or accidentally touches other objects when holding the thickness gauge for detection, it is possible to apply an inward squeezing force to the clamping rod, thereby causing the end of the clamping rod to fall off the plug, and finally causing the ultrasonic probe to fall, bump and be damaged, or affecting the operation of the thickness gauge, directly increasing the use cost of the ultrasonic thickness gauge that is easy to replace the probe.

[0025] When the probe docking seat 3 needs to be disassembled, it is only necessary to directly insert a relatively small columnar object into the inner side of the limit frame 75, and then use the inserted object to squeeze and push the reset button 74 inward, and the push plate 73 will use multiple protrusions 72 to push out the plug block 55 in the reset cavity 71, and the probe docking seat 3 can be freely disassembled.

When the plug 52 falls, the trapezoidal blocks 64 on both sides will first contact the oblique groove 62, so as to avoid direct wear of the plug block 55 and the connecting tube 61. The inner diameter of the socket 65 is directly consistent with the plug 52, and the plug 52 can be firmly inserted into the socket 65.
