Embodiment
As shown in the figure, a kind of automatic spacing switch cubicle knife switch lock, comprise housing 6, lock shaft 10, lock shaft 10 is pull in the lock shaft hole set by housing 6, described lock shaft 10 arranges hoodle, described institute axis hole be provided with two with the hole of bead 17 of hoodle adaptation, lock shaft 10 is inlaid with magnet 7, the sidewall in lock shaft hole is provided with the Hall element of this magnet 7 of induction, described lock shaft 10 is provided with pin-and-hole, and the electromagnet 7 corresponding with this pin-and-hole arranges elastic central spindle, computer key is controlled the ejection of elastic central spindle by the derived signals of Hall element and is retracted, described Hall element is by detecting the pull position of lock shaft 10 with aliging of magnet 7, the sidewall in lock shaft hole is provided with 2 Halls, described lock shaft 10 is provided with 2 pin-and-holes, described electromagnet 7 is also provided with 1 Hall, for ejection or the position that retracts of detecting core shaft, described housing 6 is fixed on the clamping plate of disconnecting link 4 by connecting bolt 9, described lock shaft 10 inserts disconnecting link 4 through installing clamping plate, to control point closing operation of disconnecting link 4, described computer key inserts locking device by connector 15.
Disconnecting link is installed on mounting panel 5, knife switch lock 1 is installed on clamping plate A2 by connecting bolt 9, disconnecting link 4 is also clamped by another clamping plate B3, the back of described lock shaft is provided with a hoodle, match with this hoodle in the hole of bead 17 set by housing 6, the distance between two hole of beads 17 is for limiting the pull stroke of lock shaft 10.
Described hoodle comprises pearl body and spring, during assembling, lock shaft 10 is pushed lock shaft hole, occur pausing when meeting first hole of bead 17, hoodle has sprung into the hole of bead 17, continues to be forced into, and external force overcomes the resistance of the 17 pairs of hoodles in the hole of bead, hoodle is released the hole of bead 17 by external force, continue forward, meet second hole of bead 17 and again occur pausing, hoodle springs in second hole of bead 17.When such hoodle springs into second hole of bead, lock shaft 10 just can be implemented in the temporarily locking automatically of deep-seated, therefrom pulls out the temporarily locking automatically that just can be implemented in shallow position when springing into first hole of bead again.
What this equipment was mainly used in switch cubicle stops power transmission, both as Fig. 3, when disconnecting link 4 shifts top onto, equipment is power transmission state, when disconnecting link 4 is left behind as Fig. 4 position, equipment is power down mode, if equipment live is operated a switch can cause device damage, and client's accident power-off, cause economic loss, this locking device for control disconnecting link 4 deciliter, this locking device adopts computer key to control, by computer key according to upper one the state of lockset and equipment, pass through Logic judgment, satisfy condition and can open locking, operation disconnecting link 4, again lock disconnecting link, treat the unlatching that again satisfies condition.
Knife switch lock 1 to be installed with 9 clamping plate A2 by the connecting bolt of front end and is fixed, push and pull out control appliance disconnecting link by lock shaft 10, there is a groove at the back of lock shaft 10, by alignment pin 17 and groove fit, realize the horizontal pull of lock shaft, there is Hall B13 and Hall C14 the side of lock shaft 10, lock shaft 10 is inlayed a magnet 7, by aliging of magnet 7 and Hall element, detect lock shaft 10 position, when lock shaft 10 pull is to certain position, the mandrel of electromagnet 11 can eject, by locked for lock shaft 10, make lock shaft 10 cannot pull, to reach interlock, detection signal in locking can import computer key into by connector 15, computer key is sent to electromagnet according to Logic judgment output signal by connector 15, to control ejection or the withdrawal of electromagnet mandrel, the Hall A12 of electromagnet 11 rear end is for detecting the state of electromagnet mandrel.
When equipment needs power transmission, disconnecting link 4 has been latched in open position as Fig. 4 and Fig. 5, now computer key inserts locking device by connector 15, first computer key detects lockset state by Hall element, and equipment state, detecting electromagnet mandrel by Hall A12 is ejecting or retracting position, if at ejected position, then judges that lockset is at blocking; Then by Hall B13 and Hall C14 judgment device state, now Hall B14 overlaps with magnet 7, lock shaft 10 is at half-travel position, with this judgment device at open position, meet power transmission condition, computer key can give electromagnet signal transmission, and electromagnet mandrel retracts, and now operating personnel operate handwheel 18 and extract lock shaft 10 out, disconnecting link is shifted onto power transmission position, pushed by lock shaft 10, Hall C14 overlaps with magnet 7, and computer key judges that locking puts in place, to electromagnet signal transmission, eject mandrel, locked lock shaft 10, completes transmission process.
This lockset also comprises end casing 8 and side cover plate 16, in order to protect internal component.
It may be noted that, above-mentioned execution mode is only the preferred embodiment of the invention, and for those skilled in the art, under the prerequisite meeting operation principle of the present invention, any equivalent or similar replacement all falls into protection scope of the present invention.
