Fig. 1 is structure front schematic view of the present utility model；
Fig. 2 is texture edge schematic diagram of the present utility model；
Fig. 3 is lock bolt structure schematic diagram of the present utility model；
Fig. 4 is circuit theory diagrams of the present utility model；
Reference：Electromagnetic lock 1, dead bolt 2, inclined-plane 21, mounting bracket 3, baffle plate 4, driving lever 5, operating mechanism 6, panel 7,
Earthed switch handle hole 8, bar hole 9, guide finger 10, electrification display 11.
Embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail；It is it should be appreciated that it is preferred that real
Example is applied only for illustrating the utility model, rather than in order to limit the scope of protection of the utility model.
As shown in Figure 1, 2, a kind of switch cabinet grounding switch electrified locking device that the present embodiment provides, including electromagnetic lock 1
With baffle plate 4, the electromagnetic lock 1 is arranged on the operating mechanism 6 of switch cubicle by mounting bracket 3, and the baffle plate 4 passes through Guiding machine
Structure is slidably disposed on the inwall of panel 7 of switch cubicle, and the guiding mechanism is the guide finger 10 being arranged on panel 7, and this is led
It is multiple to pin 10, along the both sides arranged for interval of the glide direction of baffle plate 4, can be symmetrical arranged, asymmetric can also sets, so may be used
Horizontally slipped so that baffle plate 4 does the level being oriented to guide finger 10 relatively；The electromagnetic lock 1 is provided with telescopic dead bolt 2, uses
In being butted on the one end of baffle plate 4, the other end of the baffle plate 4 can partly or entirely block the earthed switch operation being arranged on the panel 7
Hole 8, perpendicular driving lever 5 is being provided with towards the direction of panel 7 and through panel on the baffle plate 4, is also being set on the panel 7
There is the bar hole 9 for following baffle plate 4 to slide for avoiding driving lever 5, the electrification display 11 on the coil and switch cubicle of electromagnetic lock 1
One group of contact electrical connection.
With reference to shown in Fig. 4, the concrete operation step of said structure is：When primary circuit is powered, electrification display 11
Contact becomes normally opened by normally closed, and locked loop disconnects, and the dead bolt 2 of electromagnetic lock 1 stretches out and is butted on the baffle plate 4, and now, driving lever 5 is not
Baffle plate 4 can be operated to slide, and earthed switch handle hole 8 can not then be opened so that operation handle can not insert earthed switch behaviour
Make in hole 8, earthed switch is operated, the occurrence of effectively prevent switch cabinet electrified maloperation；Conversely, ought once it return
When road is not charged, the contact of electrification display 11 is normally closed, locked loop closure, and the dead bolt 2 of electromagnetic lock 1, which bounces back, causes driving lever 5
Operable baffle plate 4 slides, and now can be inserted into operation handle and carries out ground connection operation to earthed switch, safely to carry out maintenance inspection
Repair operation.
Guiding mechanism in another embodiment (is not drawn for the chute set on panel 7 and along the glide direction of baffle plate 4
Go out), the chute is two, in being arranged in baffle plate both sides up and down.So, baffle plate can be slidably matched with chute, equally may be used
To reach above-mentioned purpose.
Baffle plate 4 and driving lever 5 in the present embodiment are made of nonconducting nylon material.
As shown in figure 3, dead bolt 2 in another embodiment is being engaged close to the setting of the end face of the side of baffle plate 4 with baffle plate 4
Inclined-plane 21, the angle of inclination on preferable inclined-plane is 50 °~70 °, and baffle plate 4 (is not drawn being mounted with a spring close to the one end of dead bolt 2
Go out).So, by the cooperation on spring and inclined-plane, it may be such that electromagnetic lock when power-off bounces back dead bolt, can be pulled gear automatically by spring
Plate level moves right, so as to allow baffle plate to open earthed switch handle hole, conversely, when electromagnetic lock obtains electric stretching dead bolt, can be by
Inclined-plane promotes baffle plate level to be moved to the left automatically, while stretches the spring, should so as to allow baffle plate to block the earthed switch handle hole
It is advantageous in that, the electromagnetic lock can be made to follow electrification display to be automatically performed the shift action to baffle plate, so as to completes that ground connection is opened
Close the keying of handle hole.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, and without departing from the objective and scope of the technical program, it all should
Cover among right of the present utility model.
