Description
Technical field
The utility model relates to a kind of electromagnetic lock, particularly a kind of disengaging type electromagnetic lock.
Background technology
A kind of disengaging type electromagnetic lock is disclosed among the Chinese patent literature CN2303905Y, it comprises handle, the macro-axis that links to each other with handle, link to each other with macro-axis and can be fixed on lock on the door, it is characterized in that: on the macro-axis in lock spring collar is housed, back-moving spring, the engagement locking plate, coil holder, back-moving spring and engagement locking plate can be fixed on the lock by spring collar, on coil holder, be provided with the coil drum that is wound with coil, in the interstitial hole of coil drum, be provided with one that can slide along macro-axis and can with the engagement mandrel of macro-axis clearance meshing, the engagement mandrel is provided with the compression spring, the engagement mandrel other end can link to each other with mandrel by keyway, is with a mobilizable magnetic conduction compressing tablet on the mandrel.The disengaging type electromagnetic lock neck parts of this structure are various, the cost of manufacture height, and power consumption is big, the operation underaction, and is subject to violence damage.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of simple and reasonable, cost of manufacture is low, flexible operation, safe coefficient height, power consumption are little, the disengaging type electromagnetic lock of long service life, to overcome weak point of the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of disengaging type electromagnetic lock, comprise the dead bolt connector that joins with dead bolt, dead bolt connector one end is a square column, the other end is provided with connector, its architectural feature is slidably to dock with transition joint after connector passes the coil stationary part of loam cake and belt coil, the loam cake lid is connected on the base, the coil stationary part is slidingly installed on the location short column of loam cake, coil stationary part central authorities are provided with positioning step, positioning step is crimped on the first end of indirect, the transition joint other end is slidingly installed on the reference column in the base, is arranged with spring between transition joint and the reference column, and reference column is arranged with annular magnet outward.
Described base is provided with lower plate, and lower plate central authorities are provided with hollow location pilum, and reference column and transition joint slide in the pilum of location, and magnet is set on the pilum of location.
The magnetic field that forms behind the described coil electricity and the magnetic field of magnet attract each other.
Described connector is the cross connection-peg, and the first end of indirect is provided with cross recess.
The described transition joint other end is provided with docking recess, and docking recess central authorities are provided with the room, and the reference column end is provided with the cross plug, and plug central authorities are provided with down the room, and spring is arranged between two rooms.
When coil is not switched on, transition joint under the effect of spring, not with base on reference column come in contact, the rotating torque of dead bolt connector can not be delivered on the base, form idle running, when coil electricity, because the magnetic field that forms behind the coil electricity and the magnetic field of magnet attract each other, this magnetic force is greater than spring force, so the coil stationary part promotes transition joint and relies on reference column, and form grafting, at this moment, the rotating torque of dead bolt connector can be directly delivered on the base, can realize at last unblanking.
The utility model is not when having closing coil, even artificial attracts the magnet of electromagnet inside to unblank with external magnets, because the magnet of electromagnet inside only is to be enclosed within the transition joint outside, and no any contacting directly between the transition joint, and the dead bolt connector that violence rotation and unlocking handle are joined also can not be unblanked, can only form idle running, its safe coefficient is very high.
