Fig. 2 is the enlarged structure schematic diagram at A in Fig. 1.
Specific embodiment：
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only the part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained without making creative work belong to
The range of the utility model protection：
A kind of high voltage cabinet door interlock as shown in Figure 1 and Figure 2, including front door 1, after visit 2, fixed plate 3, support
Plate, lifter plate and telescopic rod 4.
The fixed plate 3 is fixed on the left side of 1 plate of front door and is vertically arranged with front door 1, and 2 are visited after described positioned at front door
The rear upper of plate 1, the support plate are set as L-type plate and including vertical plate 5 and level boards 6, and the vertical plate 5 is with fixing
The side plate body connection of plate 3 is fixed, and the horizontal bending in the upper end simultaneously extends to guide plate 7, one end of the level board 6 vertically to
Lower bending simultaneously forms lower guide plate 8, and the lifter plate includes straight panel 9 and hang plate 10, and hang plate 10 is connected to 9 lower part of straight panel
