Description
Technical field
The present invention relates to electric lock field, specifically a kind of electromechanical locks.
Background technology
The net door locking framework of the equipment such as substation capacitors, reactor generally uses electromagnetic lock, by the electric control function of electromagnetic lock, interlocks with related switch, disconnecting link or other net door travel switch, realize safety interlocking.Meanwhile, electromagnetic lock is also drawn make and break contact to use for miscellaneous equipment interlocking.Although existing electromagnetic lock can realize basic interlock, but in actual motion, due to reasons such as humiture, dust, mechanical damages, often there is electromagnetic lock coil burnout and the phenomenon such as travel switch is not in place, cause the reliability decrease of electromagnetic lock, affect the safety of net door locking framework.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electromechanical locks, and this electromechanical locks structure is simple, multiple functional, be especially applicable to the complex environment of net door locking framework and operating mode, locking accurately and reliably, safety is high.
For solving the problems of the technologies described above, electromechanical locks of the present invention comprises the dynamic shell that is oppositely arranged and determines shell, the dead bolt that can lean out its leading section is slidably fitted with in dynamic shell, determine shell to offer the dead bolt hole adapted with the portion of leaning out of dead bolt, its design feature is that the rearward end of described dead bolt offers allocating slot, be rotatablely equipped with by the first motor-driven first lock core in dynamic shell, first lock core is connected with the driving lever coordinated with allocating slot, the top ends of the first lock core offers the first keyhole, the housing of dynamic shell is rotatablely equipped with by the second motor-driven second lock core, second lock core is connected with the baffle plate that the first keyhole can be covered, the top ends of the second lock core offers the second keyhole, move shell and determine to install primary importance sensor between shell, installing the second place sensor can responding to latch bolt position in dynamic shell, on the housing of dynamic shell, installation can respond to the 3rd position sensor of baffle position, dynamic shell built-in control circuit, the control end of two motors and the signal output part of each position sensor are all electrically connected on the control circuitry.
Adopt said structure, when door-closing in-place, determine shell corresponding with dynamic shell, primary importance sensor trigger signal also exports to control circuit, control circuit controls the first motor and rotates forward, and the first driven by motor lock core rotates, and lock core drives driving lever to swing, driving lever stirs dead bolt forward slip by allocating slot, thus completes action of locking; When having locked, dead bolt puts in place, now second place sensor trigger signal export to control circuit, and control circuit gets out interlocking signal and calls for external circuit.
From the above, the present invention can realize electronic locking, in order to ensure safety, the present invention does not support driven opening lock function, only support manually to unblank, but manually unblank also to need to carry out when satisfied outside interlock condition, need control circuit first judge after could allow manually to unblank, therefore, under locking state, baffle plate keeps off on the first keyhole, only has when control circuit judges that outside interlock condition meets, the second electric machine rotation could be controlled baffle plate is moved away, and then manually unblank.Obviously, this vibrational power flow further ensures security reliability, more effectively avoids door lock and opens by mistake and open phenomenon.
Second lock core arranges the second keyhole, and this keyhole only in case of emergency uses.Namely when needs promptly open the door, and control circuit judges that outside interlock condition does not meet or the second electrical fault, now opens the second lock core by the second keyhole, butterfly, exposes the first keyhole, and then manually unblank.
For the motorized drive structure of dead bolt, driving gear installed by the power output shaft of described first motor, the first lock core is provided with the driven gear engaged with driving gear.Described driven gear is sector gear.Utilize gear drive, ensure that the reliability of transmission.Because the first motor only need drive driving lever rotation, therefore, driven gear adopts sector gear, thus can effectively conserve space and cost.
