Abstract
An either-or interlocking device for double power switch cabinets comprises two power switch cabinets. Each power switch cabinet is equipped with a power on-and-off operating shaft inside, and an operating hole convenient for operating the power on-and-off operating shaft is arranged on each power switch cabinet. The either-or interlocking device further comprises two cylinders which are arranged at the operating holes, and share the same key and prevent the key from being drawn out in an unlocking state, plugs of the cylinders can rotate, and baffles arranged on the plugs can rotate along with the plugs. When the cylinders are in a closed state, the baffles block the operating holes, and then the power on-and-off operating shaft can not be operated. The alternative interlocking device can realize interlocking of two power supplies, and guarantees utilizing one power supply to supply power during power conversion, thereby avoiding malfunction. The alternative interlocking device is simple and practical in structure, high in operating reliability and low in implement cost, and is easy to be achieved by modifying the exiting power switch cabinet.

Embodiment
Twin-power switch cabinet alternative interlock of the present utility model comprises two mains switch cabinets.During power supply, a mains switch cabinet energized, another mains switch cabinet connects another power supply as standby, and is in closed condition.Be provided with power supply in each mains switch cabinet and close the branch operating mechanism, power supply closes the branch operating mechanism and is provided with power supply and closes the branch operating axis.On the header board of each mains switch cabinet, be provided with and be convenient to the handle hole that operating power is closed the branch operating axis, can use spanner to extend into from handle hole that rotary power source closes the branch operating axis in the mains switch cabinet, connect or powered-down.
Twin-power switch cabinet alternative interlock of the present utility model fixedly mounts tapered end respectively near two mains switches handle hole cashier's office in a shop, two tapered ends have identical key, lock core can rotate, when tapered end is in opening, key can not be extracted out from tapered end, when guaranteeing that like this a tapered end is opened, another tapered end can only be in closed condition.Baffle plate is installed on the lock core, and baffle plate can rotate with lock core.Below, in conjunction with the accompanying drawings the utility model is elaborated.
The schematic diagram of mains switch cabinet when Fig. 1 and Fig. 2 are in closed condition for the utility model tapered end, as shown in the figure, tapered end 1 is installed on the lock support 2, lock support 2 is fixedly linked with the header board 3 of mains switch cabinet, tapered end 1 is positioned at the below of handle hole 4, be provided with baffle plate 5 on lock core, baffle plate 5 can rotate with lock core, is provided with power supply in the mains switch cabinet and closes branch operating axis 6.When tapered end 1 was in closed condition, baffle plate 5 blocked handle hole 4, can't use spanner to stretch into mains switch cabinet operating power from handle hole 4 and close branch operating axis 6.
Further, being provided with first limit body, 7, the first limit bodies 7 on lock core can rotate with lock core, and first limit body 7 is positioned at the mains switch cabinet; Close at power supply and to be provided with second limit body 8 on the branch operating axis 6.When tapered end was in closed condition, first limit body 7 was positioned at the left side of tapered end 1, and second limit body 8 is positioned at the right side that power supply closes branch operating axis 6.
The baffle plate 5 and first limit body 7 can be designed as parts.
When the needs energized, use key to insert mains switch tapered end 1 cashier's office in a shop, clockwise rotate 90 ° and open tapered end 1, the baffle plate 5 and first limit body 7 clockwise rotate thereupon.At this moment, referring to Fig. 3 and Fig. 4, baffle plate 5 turns to tapered end 1 right side, and first limit body 7 turns to tapered end 1 top.Then, use spanner to extend in the mains switch cabinet from handle hole 4, the power supply that turns clockwise closes 90 ° of energized of branch operating axis, second limit body 8 turns to the bottom that power supply closes branch operating axis 6 thereupon, be positioned at the top of first limit body 7, have the space between first limit body 7 and second limit body 8.At this moment, if tapered end 1 is rotated counterclockwise to closed condition, second limit body 8 will withstand first limit body 7 and stop first limit body 7 to be rotated further, and then restriction tapered end 1 rotates.
If want to close locking head 1, must rotate counterclockwise power supply earlier and close branch operating axis 6 deenergizations, afterwards, just can rotate counterclockwise tapered end 1 tapered end 1 is closed, extract key then.When needs use stand-by power supply, use key to open another mains switch tapered end 1 cashier's office in a shop, rotary power source closes branch operating axis 6 energized.
The utility model can be realized the interlocking of two power supplys, when power source conversion, guarantees to have only one road power supply to power, and misoperation can not occur.The utility model is simple in structure, practical, integral layout compactness, rationally, and operational reliability height, and realize that cost is low is easy to the existing power supply switch cubicle transformed and obtains device of the present utility model.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
