Abstract
The utility model discloses one kind two to control safety lock, under normality, electromagnet no power, can avoid electric energy loss；When upper clutch block after key inserts with key turns, then electromagnet is powered and adhesive lower clutch block is away from upper clutch block so that key dallies.Two controls safety lock provided by the utility model is realized under automatically controlled state, and mechanical key can not unlock；Under off-position, it can be unlocked by mechanical key.
Description
Technical field
Electronic lock technical field is the utility model is related to, more particularly to one kind two controls safety lock.
Background technology
Current electronic lock all carries mechanical key, and even under automatically controlled state, mechanical key can also be normal
Use.So so that the use of mechanical key is uncontrolled, it is difficult to ensure safety of unlocking.But if mechanical key is banned completely
Spoon, can not unlock in the state of power-off again.
Utility model content
Based on technical problem existing for background technology, the utility model proposes one kind two to control safety lock.
The utility model proposes one kind two control safety lock, including：Upper clutch block, lower clutch block, angular displacement sensor, lock
Core cam, electromagnet and electric-controlled switch；
Upper clutch block is provided with keyhole, and lower clutch block is slidably mounted between upper clutch block and electromagnet, lower clutch block
Engage and as upper clutch block rotates with upper clutch block under normality, lock core cam is connected with lower clutch block；Electromagnet "on" position
Lower adhesive lower clutch block, lower clutch block is away from upper clutch block；
Angular displacement sensor, which is arranged on, is used for the rotational angle for detecting upper clutch block on upper clutch block；Electric-controlled switch and electromagnetism
Iron coil is connected, and the automatically controlled end of electric-controlled switch is connected with angular displacement sensor.
Preferably, lock core cam and lower clutch block dismantling connection, under normality, lock core cam is connected with lower clutch block, and lock
Core cam rotates with lower clutch block；Under electromagnet "on" position, lower clutch block to electromagnet move, lock core cam on from
The movement and lower clutch block for closing block depart from.
Preferably, lower clutch block is provided with open slot, the installation of lock core cam rotation, the lower clutch that its one end is inserted under normality
In the open slot of block.
Preferably, lock core cam is fixedly connected with lower clutch block.
Preferably, upper clutch block is provided with groove close to one end of lower clutch block, and lower clutch block is provided with and groove match
Projection, upper clutch block and lower clutch block are fastened by groove and projection.
The utility model proposes one kind two control safety lock, under normality, electromagnet no power, electric energy loss can be avoided；When
Upper clutch block is with key turns after key insertion, then electromagnet is powered and adhesive lower clutch block is away from upper clutch block so that
Key dallies.Two controls safety lock provided by the utility model is realized under automatically controlled state, and mechanical key can not unlock；Off-position
Under, it can be unlocked by mechanical key.
Brief description of the drawings
Fig. 1 be the utility model proposes one kind two control safety lock normality under structure chart；
Fig. 2 is structure chart under the two safe lock key constrained states of control.
Embodiment
Reference picture 1, the utility model proposes one kind two control safety lock, including：Upper clutch block 1, lower clutch block 2, angle position
Displacement sensor, lock core cam 3, electromagnet 4 and electric-controlled switch.
Upper clutch block 1 is provided with keyhole, and lower clutch block 2 is slidably mounted between upper clutch block 1 and electromagnet 4, under from
Engage under the conjunction normality of block 2 with upper clutch block 1 and as upper clutch block 1 rotates, lock core cam 3 is connected with lower clutch block 2, such as Fig. 1
It is shown.Adhesive lower clutch block 2 under the "on" position of electromagnet 4, lower clutch block 2 is away from upper clutch block 1, as shown in Figure 2.
Angular displacement sensor, which is arranged on, is used for the rotational angle for detecting upper clutch block 1 on upper clutch block 1.Electric-controlled switch and electricity
The coil of magnet 4 is connected, in this way, electric-controlled switch closes, then work of electromagnet is with adhesive lower clutch block.The automatically controlled end of electric-controlled switch with
Angular displacement sensor connects, and electric-controlled switch is normal open switch, and the electric signal for only receiving angular displacement sensor is just switched to often
Closed state, and angular displacement sensor only just sends electric signal when detecting that upper clutch block rotates to electric-controlled switch.
In this way, in present embodiment, under normality, electromagnet no power, electric energy loss can be avoided；When upper clutch block is in key
With key turns after insertion, then electromagnet is powered and adhesive lower clutch block is away from upper clutch block so that key dallies.This implementation
The two control safety locks that mode provides are realized under automatically controlled state, and mechanical key can not unlock；Under off-position, mechanical key can be passed through
Spoon is unlocked.
In present embodiment, lower clutch block can be arranged on the shell of lock by spring, to ensure that lower clutch block exists
Smooth reset after electromagnet power-off.
In present embodiment, lock core cam 3 and the dismantling connection of lower clutch block 2, under normality, lock core cam 3 and lower clutch block 2
Connection, and lock core cam 3 is rotated with lower clutch block 2.Under the "on" position of electromagnet 4, lower clutch block 2 moves to electromagnet 4, lock
Core cam 3 departs from the movement of upper clutch block 1 with lower clutch block 2.That is, lock core cam rotation is arranged on perpendicular to lower clutch block
In the plane for translating track.In this way, avoiding lock core cam as lower clutch block translates together, be advantageous to reduce the volume of lock.
Specifically, in present embodiment, lower clutch block 2 is provided with open slot 5, and lock core cam 3 is rotatablely installed, under its one end insertion normality
Lower clutch block 2 open slot 5 in.
It is fixedly connected when it is implemented, may also set up lock core cam 3 with lower clutch block 2.
In present embodiment, upper clutch block 1 is provided with groove 6 close to one end of lower clutch block 2, lower clutch block 2 be provided with
The projection 7 that groove 6 matches, upper clutch block 1 and lower clutch block 2 are by groove 6 and projection 7 fastens and lower clutch block section
As upper clutch block rotates.In present embodiment, groove is rotation asymmetry structure, to avoid lower clutch block and upper clutch block pair
In the case of connecing, upper clutch block idle running.
It is described above, the only 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 scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model
Within enclosing.
