From, unlock.It is additionally provided on the sliding block 112 for by the lock tongue handle 115 of 102 manual actuation of lock tongue to unlocked state.
The operation principle that the present invention provides a kind of passive electromagnetic lock with automatic blocking function of low-power consumption is：It, should when beginning
Electromagnetic lock is (such as Fig. 2) in the unlocked state, at this point, locking elastic drive unit (energy-stored spring a 113) energy storage, unlocks elasticity and drive
Moving cell (energy-stored spring b 114) non-energy storage；When electric drive locking mechanism 103 (motor 106) receives incoming telephone signal (high-voltage board
Suddenly incoming call or when the not charged artificial locking of high-voltage board), electric drive locking mechanism 103 releases the locking to lock tongue 102, i.e., electric
Machine 106 is rotated with moving cam 110, is acted on the driving tail portion 107b of locking wraping plate 107, makes the movement of locking wraping plate 107, locking
Clamp 107a detaches (such as Fig. 3) with unlock clamping block 104b, and being latched elastic drive unit at this time, (energy-stored spring a 113 discharges energy
Measure) it pushes lock tongue 102 to move in lockhole 101, realize locking, this process motor 106 is rotated further, with moving cam 110 and lock
Determine the driving tail portion 107b separation of wraping plate 107, (such as attached drawing 4), while locking wraping plate 107 (under the action of resetting spring 109)
It automatically resets, so that locking clamp 107a is resisted the locking clamping block 104a on blocking lock tongue 102, at this time entire lock body
It is in the lock state, is latched elastic drive unit (energy-stored spring a 113) non-energy storage, unlock elastic drive unit (energy-stored spring b
114) energy storage；When electric drive locking mechanism 103 (motor 106) receives unlocking signal, the releasing pair of electric drive locking mechanism 103
The locking of lock tongue 102, i.e. motor 106 are rotated with moving cam 110, are acted on the driving tail portion 107b of locking wraping plate 107, make lock
Determine the movement of wraping plate 107, locking clamp 107a detaches (such as Fig. 3) with locking clamping block 104a, unlock elastic drive unit (storage at this time
Energy spring b 114 releases energy) it pushes the movement of lock tongue 102, locking clamp 107a and locking clamping block 104a is made to be staggered and (such as scheme
5) it, to the earthing knife-switch of operation high-tension apparatus, then needs artificial (holding lock tongue handle 115) manually by the pressing of lock tongue 102, drive extremely
Unlocked state (such as Fig. 2).
In this way, electromagnetic lock of the present invention only needs the short time to touch electric drive locking mechanism in unlock and latching process,
Required minimum energy, and working power is only from the induced electricity that high voltage display device takes, and efficiently solves existing
The big problem of passive electromagnetic lock power problems is convenient for the installation of electromagnetic lock, while can send a telegram here suddenly in high-voltage board and prevent artificial mistake
Operational grounding switchs, and substantially increases the safety of operation and the stability of power transmission.
Certainly, the locking elastic drive unit and unlock elastic drive unit can also be to be respectively arranged on 112 liang of sliding block
The energy storage shrapnel of side, the energy storage shrapnel are simultaneously drivingly connected with sliding block 112 or lock tongue 102.And lock tongue 102 also can be by using
Rail structure is movably mounted on lock body 100, such as：Lock tongue 102 is equipped with line slide rail, and the lock tongue 102 can pass through it
The sliding slot or sliding block being equipped with actively are connected on line slide rail, are latched elastic drive unit and unlock flexible drive list at this time
Member can be energy storage shrapnel, and the energy storage shrapnel is drivingly connected with lock tongue 102.
The foregoing is merely the preferred embodiment of the present invention, are not intended to limit the scope of the invention, every at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
In the scope of patent protection that other related technical areas are included in the present invention.
