Description
Technical Field
The invention relates to the technical field of bus plug-in boxes, in particular to a novel turntable interlocking plug-in box.
Background
In the prior art, an intensive bus plugging box usually adopts a mode that a locking pin is clamped and pressed with a bus cover plate (as shown in fig. 10), so that the plugging and unplugging of the plugging box are limited. And simple limit interlocking is arranged between the locking leg and the plug box door plate, and the locking leg cannot be opened after the box door is closed. Meanwhile, the box door is controlled by an operating handle of the manual operating mechanism, and the box door can be opened only when the handle is in a brake separating position, so that the aim of preventing the jack box from being plugged during closing is fulfilled. However, as the electrification degree of the product is deepened, when an electric operating mechanism is selected, because the electric operating mechanism does not have an external operating handle, the situation that the door can still be opened under a closing state occurs. Therefore, the common box door interlock cannot be used under the premise of using electric operation. In this context, we have newly developed a jack box locking pin interlocking mode.
