Embodiment
For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and cooperates appended graphic elaborating as follows.
With reference to legend, a kind of interlock of transformer case door comprises transformer cabinet 1, it is characterized in that: said transformer cabinet 1 installed in front has cabinet door 2; Said cabinet door 2 rear sides are equipped with the link lock 3 with cabinet door 2 upper and lower side snap fit; Said link lock connecting rod is provided with a catch 4; Said cabinet door 2 rear sides are provided with an electromagnetic lock 5, and the dead bolt 51 of said electromagnetic lock is positioned at catch and is used to prevent that near link lock tapered end 32 1 sides connecting rod from moving.
Above-mentioned dead bolt 51 is in the same plane with catch, and this plane and cabinet door 2 parallel.
Above-mentioned catch 4 and connecting rod be vertical to be connected and towards cabinet door 2 sides.
Among the utility model embodiment one:
Above-mentioned catch 4 is arranged on the last connecting rod 311 of link lock, and dead bolt 51 is positioned at catch 4 downsides.
Among the utility model embodiment two:
Above-mentioned catch 4 is arranged on the lower link 312 of link lock, and dead bolt 51 is positioned at catch 4 upsides.
In the utility model: connecting rod comprises connecting rod and lower link.
In the utility model one preferred embodiment, the cabinet door of cabinet Men Weishuan open form, catch are a L type brace, and one holds capable being welded on the connecting rod level with both hands; The other end cooperates with dead bolt, and is under the state of energising in the transformer room, and the dead bolt of electromagnetic lock is the state that maintenance is stretched out, and so just can block catch; Just prevented moving of connecting rod, made the cabinet door remain at closed state, prevented that the workman from opening by mistake the cabinet door; Avoid the workman by electricity, and in the transformer room during no power, the dead bolt of electromagnetic lock is removed the constraint to catch; Connecting rod can easy on and off move, the cabinet door just can be opened, the work that the workman can keep in repair or detect.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
