Abstract

A rain/snow-proof brake pull-rod with an electroscope comprises a pull hook and a pull rod, wherein, the electroscope is connected between the pull hook and the pull rod, the pull hook is connected with the top end of the electroscope and taken as an electricity detection terminal, both the top end and the side surface of the casing of the electroscope adopt closed structures, a water-proof rim extending outward and downward is arranged at the lower part of the casing, and a group of insulators are connected in series on the pull rod. The utility model has the following advantages: the combination of the electroscope and the brake pull-rod is characterized by portability and convenient use; the circuit of the electroscope is mounted in the casing with a sealed top, thereby preventing the entry of rain or snow and ensuring normal operation of the circuit; and the insulators, a water-proof jacket and a hand-protection water-proof jacket on the pull rod form a multi-water-proof barrier which can effectively prevent rain or slush from wetting the whole surface, thereby avoiding the formation of a conductive path, averting the occurrence of electric shock accident, and enabling the brake pull-rod to meet the demands for electricity detection in rainy or snowy days. The pull hook and the pull rod can be connected directly when the electroscope is considered as unnecessary, so that the brake pull-rod is flexible and convenient, and can meet different needs.
