Description
Technical field
The utility model relates to the two-door interlocking device of a kind of switch cubicle, belongs to switch cubicle technical field.
Background technology
40.5kV system switching cabinet is because of the requirement of electric field to electric clearance, and overall dimension is larger, and common cabinet is wide all more than 1400mm.Consider the structural strength of Hinge for cupboard door, and cost of manufacture, double swing doors conventionally all adopted.
Current existing double swing doors, is all that secondary door-plate is first shut substantially, then manually pushes away the inner locking bar of lock, after fixing, then closes main door-plate, and the dead bolt of its cabinet door lock fastens on the secondary door-plate of first shutting, and completes locking.But often due to human negligence, do not close the door in order, cause the false pass of cabinet door, cause security incident.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has been to provide simple in structure, easy to operate, the two-door interlocking device of safe and reliable switch cubicle.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the two-door interlocking device of a kind of switch cubicle, comprise L-type base plate and cover plate, the one side of described L-type base plate is close to the boundary frame area of switch cubicle, and be fixed on the boundary frame area of switch cubicle, on another side, be provided with latch arm hole, and above latch arm hole, be stamped cover plate, one end of described cover plate is hinged on L-type base plate, cover plate is fixed with bent plate on inside edge, face and the cover plate of described bent plate are horizontally disposed with, on another side, be provided with back-moving spring, described back-moving spring one end is fixed on bent plate, the other end is fixed on L-type base plate, the arranged outside of described cover plate has and is vertically provided with riser, in contrast should, on the secondary door-plate of switch cubicle, be provided with the push rod for ejection riser.
Preferably, the inside edge of described cover plate is also provided with limiting plate.
Preferably, described L-type base plate is aluminizing zine plate.
The utility model is simple in structure, easy to use, by being provided with interlocking device at switch cubicle boundary frame area, only has while formerly closing secondary door-plate, and main door-plate could normally lock, and increases security reliability.
Brief description of the drawings
Fig. 1 is the structural representation of the two-door interlocking device of a kind of switch cubicle of the utility model.
In figure: 1 is L-type base plate, 2 is cover plate, and 3 is bent plate, and 4 is back-moving spring, and 5 is riser, and 6 is push rod, and 7 is latch arm hole, and 8 is limiting plate, and 9 is secondary door-plate, and 10 is main door-plate, and 11 is boundary frame area.
Embodiment
The specific embodiment of the utility model being done below in conjunction with accompanying drawing is described further.
As shown in Figure 1, the two-door interlocking device of a kind of switch cubicle, comprise L-type base plate 1 and cover plate 2, the one side of described L-type base plate 1 is close to the boundary frame area of switch cubicle, and be fixed on the boundary frame area of switch cubicle, on another side, be provided with latch arm hole 7, and latch arm hole 7 is stamped cover plate 2 above, one end of described cover plate 2 is hinged on L-type base plate 1, cover plate is fixed with bent plate 3 on 2 inside edges, face and the cover plate 2 of described bent plate 3 are horizontally disposed with, on another side, be provided with back-moving spring 4, described back-moving spring 4 one end are fixed on bent plate 3, the other end is fixed on L-type base plate 1, the arranged outside of described cover plate 2 has and is vertically provided with riser 5, in contrast should, on the secondary door-plate of switch cubicle, be provided with the push rod 6 for ejection riser 5.
The inside edge of described cover plate 2 is also provided with limiting plate 8.
Described L-type base plate 1 is aluminizing zine plate.
When concrete use, L-type base plate 1 adopts aluminizing zine plate to make, and a face of L-type base plate 1 is bolted on switch cubicle boundary frame area 11, and one end of cover plate 2 is hinged on by bearing pin on another face of L-type base plate 1, make cover plate 2 can cover latch arm hole 7, and can rotate around bearing pin, the inner side of cover plate 2 is welded with bent plate 3, is connected with back-moving spring 4 on bent plate 3, facilitate cover plate 2 to reset, on the secondary door-plate of switch cubicle, be provided with push rod 6, push rod 6 can ejection riser 5, and cover plate 2 is rotated around bearing pin.
When cabinet door is during in opening, under the effect of reset tension spring 4, cover plate 2 covers latch arm hole 7, if now close main door-plate, and latch arm hole 7 cresteds, locking bar cannot insert, and cabinet door cannot be closed.Must first close secondary door-plate, when secondary door-plate cuts out, the push rod 6 ejection risers 5 of installing on it, make cover plate 7 rotate around bearing pin, and latch arm hole 7 is opened, and in the time closing main door-plate, locking bar can insert latch arm hole 7 smoothly, and cabinet door lock closes, and uses more safe and reliable.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above; but the utility model is not limited to above-described embodiment; in the ken possessing those of ordinary skill in the art; can also under the prerequisite that does not depart from the utility model aim, make obtaining various variations, also should be considered as protection range of the present utility model.
