Abstract

The invention provides an interlocking mechanism of a jack box; the interlocking mechanism comprises a left locking plate, a right locking plate, a pin shaft, a rotating plate, a shaft sleeve, a gear and a closing plate, wherein the pin shaft is sequentially penetrated through the rotating plate, the shaft sleeve and the gear and is fixed on a shell of the jack box by the shaft sleeve; the pin shaft is fixedly connected with the rotating plate and the gear; the left locking plate and the right locking plate are respectively fixed on the closing plate by bolts; horizontal long holes are arranged on positions of the left locking plate and the right locking plate, which are provided with the bolts; a left pothook is arranged at the lower part of the left locking plate, and a left rack is arranged at the lower part of the left locking plate; a right pothook is arranged at the lower part of the right locking plate, and a right rack is arranged at the lower part of the right locking plate; when the left locking plate and the right locking plate are arranged on the closing plate, the left pothook and the right pothook are at the same height; when the closing plate is fixed on the sell of the jack box, the left rack and the right rack are respectively matched with the gear and are horizontally distributed above and under the gear; and the interlocking mechanism has the advantages of high locking precision, strong generality, high reliability and convenient operation.

Description

technical field [0001] The invention relates to a plug-in box interlocking mechanism, in particular to a plug-in box interlocking mechanism mainly used in various bus duct feed units, and belongs to the technical field of power transmission and distribution safety. Background technique [0002] The busway series products are developing in the direction of high performance, high quality, and safe operation, and at the same time, the performance of the plug-in box of the feeder unit is also required to develop in the direction of diversification and humanization. As a functional unit of the power transmission busway, the plug-in box plays the role of distributing electric energy in the busway system. Therefore, after the on-site installation of the busbar is completed, the user will frequently touch and operate the plug-in box. In order to ensure the safety of the plug-in box and the operator It is required that the plug-in box has the characteristics of reliable design and co...
