Abstract
The present invention belongs to the field of sound wave detection and discloses an extension rod for noise detection, comprising a main rod, an extension rod, a fixed piece and a signal line. The main rod and the extension rod are hollow tubes. The extension rod is movably nested in the main rod, and the extension rod and the main rod are fixed through the fixed piece. The top end of the extension rod is connected with a noise detection probe. One end of the signal line is connected with the noise detection probe, and the other end is connected with a noise tester though traversing the extension rod and the main rod. According to the extension rod for noise detection, through a method of mounting the noise detection probe on the end part of a telescopic long rod, noise measurement is more convenient, so the pain of climbing up and down for a testing worker is prevented, and personal safety is ensured. The signal line is extended to the inner part of the extension rod and the main rod through a cable hole, the signal line is prevented from being suspended outside and further from being in contact with an electrified apparatus by mistake and the apparatus is prevented from interfering with testing signals, hence detection quality is guaranteed. An elastic tube groove is arranged on the upper part of a probe support, and the noise detection probe is convenient to be clamped in the elastic tube groove through a notch, so dismounting is convenient.
