Tool lock it is unique difference lies in a kind of simply more unlocking approach of, electric control lock, in this way, only increase the convenience of electric control lock,
It can not really ensure the security of mechanical lock.
Utility model content
Based on technical problem existing for background technology, the utility model proposes a kind of constrained door lock of key.
The utility model proposes a kind of constrained door lock of key, including：Lock core shaft, moving block, lock core cam, inserted link,
First electromagnet, the second electromagnet, spring and electric-controlled switch；
Lock core shaft is equipped with strip groove, and moving block is equipped with strip bulge, and strip bulge is inserted into strip groove, and bar shaped is convex
The width risen is less than strip groove；
Lock core cam is installed on moving block and as moving block rotates, and lock core cam is equipped with limit hole；Inserted link and
One electromagnet is composed of a fixed connection sliding shoe, and being positioned at for inserted link is corresponding with limit hole, and the second electromagnet is fixedly mounted and leads to
Cross spring and connect the first electromagnet；
Under spring normality, inserted link is away from limit hole；Under "on" position, the first electromagnet and the second electromagnet magnetic direction phase
Instead, inserted link insertion limit hole；
Angular displacement sensor is installed, the first magnet spool and the second magnet spool pass through electricity in lock core shaft
Control switch series-connection power supplies, angular displacement sensor connect the control terminal of electric-controlled switch；Electric-controlled switch is normal open switch, when angular displacement passes
Sensor exports electric signal, electric-controlled switch closure.
Preferably, the first magnet spool and the second magnet spool be in parallel or in series.
Preferably, inserted link is integrally formed with the first electromagnet.
In the utility model, under normal power supply state, angular displacement sensor detects that lock core shaft rotates i.e. key and is inserted into
Afterwards, the first electromagnet and the second work of electromagnet are controlled to drive inserted link to be inserted into limit hole by electric-controlled switch, at this time spring drawing
Stretch.And angular displacement sensor is not detected by lock core shaft's rotation, or in the case of electrically disconnected, the first electromagnet and the second electricity
Magnet can not work, then spring maintains normality, and inserted link exits limit hole, and lock core cam is freely rotated.
By the cooperation of strip groove and strip bulge in the utility model, when key is inserted into lock core shaft and drives lock core shaft
During rotation, lock core shaft drives moving block to rotate.Again since the width of strip bulge is less than strip groove, so, moving block turns
Dynamic hysteresis and lock core shaft.So as to the mobile offer time enough to inserted link.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of constrained door lock normal condition lower structure figure of key；
Fig. 2 be the utility model proposes a kind of constrained door lock constrained state lower structure figure of key；
Fig. 3 is lock core shaft and rotates block structural diagram.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, the utility model proposes a kind of constrained door lock of key, including：Lock core shaft 1, rotate
Block 2, lock core cam 3, inserted link 4, the first electromagnet 5, the second electromagnet 6, spring 7 and electric-controlled switch 8.
Lock core shaft 1 is equipped with strip groove 1A, and moving block 2 is equipped with strip bulge 2A, and strip bulge 2A insertion bar shapeds are recessed
The width of groove 1A, strip bulge 2A are less than strip groove 1A.In this way, by the cooperation of strip groove 1A and strip bulge 2A, when
When key is inserted into lock core shaft 1 and drives the rotation of lock core shaft 1, lock core shaft 1 drives moving block 2 to rotate.Again due to strip bulge 2A's
Width is less than strip groove 1A, so, rotational hysteresis and the lock core shaft 1 of moving block 2.
Lock core cam 3 is installed on moving block 2 and as moving block 2 rotates, when lock core cam 3 turns an angle, lock
Tongue is retracted so as to unlock.Lock core cam 3 is equipped with limit hole 4A.4 and first electromagnet 5 of inserted link is composed of a fixed connection sliding shoe,
Being positioned at for inserted link 4 is corresponding with limit hole 4A, and the second electromagnet 6 is fixedly mounted and connects the first electromagnet 5 by spring 7.
Under 7 normality of spring, for inserted link 4 away from limit hole 4A, lock core cam 3 can be with the case where key is inserted into lock core shaft 1
Moving block 2 to be freely rotated, so as to unlock.Under "on" position, the first electromagnet 5 and 6 magnetic direction of the second electromagnet are on the contrary,
One electromagnet 5 slides under magnetic fields to the direction away from the second electromagnet 6, so that inserted link 4 is inserted into limit hole 4A limitation locks
Core cam 3 rotates so that in the energized state, mechanical key failure.
Angular displacement sensor 9 is installed, the coil of the coil of the first electromagnet 5 and the second electromagnet 6 is logical in lock core shaft 1
8 series-connection power supplies of electric-controlled switch are crossed, angular displacement sensor 9 connects the control terminal of electric-controlled switch 8.Electric-controlled switch 8 is normal open switch, when
Angular displacement sensor 9 exports electric signal, and electric-controlled switch 8 closes.In this way, under normal power supply state, angular displacement sensor 9 detects
It is after key is inserted into be rotated to lock core shaft 1, controls the first electromagnet 5 and the second electromagnet 6 to work to drive by electric-controlled switch 8
Inserted link 4 is inserted into limit hole 4A, and spring 7 stretches at this time.And angular displacement sensor 9 is not detected by lock core shaft 1 and rotates, or power supply
In the case of disconnection, the first electromagnet 5 and the second electromagnet 6 can not work, then spring 7 maintains normality, and inserted link 4 exits limit hole
4A, lock core cam 3 are freely rotated.
In present embodiment, the coils from parallel connection of coils of the coil of the first electromagnet 5 and the second electromagnet 6, or the first electromagnet 5
Coil, the second electromagnet 6 coil and electric-controlled switch 8 be sequentially connected in series after connect power supply.
In present embodiment, inserted link 4 is integrally formed with the first electromagnet 5, to ensure that inserted link 4 is opposite with the first electromagnet 5
The stabilization of position.
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
