VIBRATION DETECTING INSTRUMENT CAPABLE OF ADJUSTING LENGTH OF DETECTING HEAD

WIPO Patent Application WO/2022/082882

A1

A vibration detecting instrument capable of adjusting the length of a detecting head, comprising a first support rod (1), a second support rod (3), and a vibration detecting instrument body (4). A slot (2) is formed in the upper end of the first support rod (1), the second support rod (3) is disposed inside the slot (2), the first support rod (1) is provided with a vibration detecting instrument length adjusting apparatus, a rubber pad (20) is fixedly connected to the upper end of the second support rod (3), circular recesses (22) are formed in the upper end of the rubber pad (20), first springs (21) are fixedly connected to the inner bottom surfaces of the circular recesses (22), and a connecting rope (19) is fixedly connected to the upper ends of the first springs (21). The vibration detecting instrument has simple adjusting steps and is easy to operate, so that the time for an operator to adjust the length can be reduced; and the length adjustment cannot cause the length deviation due to later article vibration, so that the detecting result deviation is avoided, and normal detection of the vibration detecting instrument can be ensured.
