A lock core of the lock body of the permanent-magnetic lock is made of an Nd-Fe-B rare earth permanent magnetic material; the residual magnetism, coercive force, intrinsic coercive force, magnetic energy product, and other magnetic properties of the Nd-Fe-B rare earth permanent magnetic material are fully utilized; a driving device drives the lock core to rotate in the lock body to change the magnetic line of force of the lock core; when the magnetic line of force closes, a lockset pulls in; and when the magnetic line of force is disconnected, the lockset releases.
Description
Technical field
The present invention relates to a kind of magnetic force lock, the permanent-magnetic lock of particularly a kind of employing neodymium iron boron (Nd-Fe-B) rare earth permanent-magnetic material.
Background technology
Common in the market magnetic force lock all is made up of adsorbent equipment and lock body, utilizes the principle of electromagnet, and during energising, lock body is adsorbed on the adsorbent equipment, realizes the locking of magnetic force lock, and during outage, lock body separates with adsorbent equipment, realizes unblanking of magnetic force lock; Yet mainly there is following problem in magnetic force lock common on the existing market:
1, need be when the magnetic force lock is in blocking to the lock body continued power, the energy of consumption is big, and calorific value is also big simultaneously, and application life is more limited;
2, when magnetic force is locked artificial or accident power-off, will let pass automatically, lose the safety precaution meaning;
3, existing magnetic force lock must be realized the control operation to the magnetic force lock by subsidiary control circuit.
One Chinese patent application number is that 200620014212.6 utility model patent discloses a kind of magnetic force lock; Comprise lock body and latch plate assembly; Wherein said lock body is built-in with the dead bolt assembly and unblanks assembly, and described latch plate assembly includes the buckle magnet steel, and described dead bolt assembly includes the dead bolt magnet steel; Heteropole is inhaled mutually between described buckle magnet steel and said dead bolt magnet steel; Said dead bolt assembly is hidden in when lockset is in opening in the lockset, and when lockset need cut out, said latch plate assembly contacted with said dead bolt assembly; Thereby described buckle magnet steel attracts said dead bolt magnet steel to drive said dead bolt assembly fastens to said latch plate assembly, realizes the function that lockset cuts out.Make said dead bolt assembly stretch out lockset to have avoided it to stretch out to hurt sb.'s feelings or receive accidental shock and damage though this magnetic force lock is simple in structure, need not spring force or other complicated machinery transmissions; Because it need not spring force or the complicated machinery transmission promotes said dead bolt assembly, thereby has significantly reduced fault rate, but since described dead bolt assembly by the frame for movement transmission, so its volume is relatively large.
One Chinese patent application number is that 200620014212.6 utility model patent discloses a kind of magnetic force lock, adsorption plate is installed on door, and on the corresponding doorframe position of this adsorption plate, is provided with the electromagnetic lock body; Said electromagnet is processed with non-silicon steel metal, and constitutes E bar group by the E sheet of coil and predetermined sheet number and organize to establish and form, by on the joint suction magnetic surface of the E sheet that constitutes E bar group; Increase the salient point that engages the suction magnetic surface, can effectively improve the magnetic force of electromagnetic lock, reach the sorption of the forceful electric power magnetic force of the adsorption plate that is provided with on the opposite house; Force open the door when lock with brute force when running into the burglar; Can in blink, door not pried open, or rushed open by being imposed weight, thereby can delay deathwatch's time; Make things convenient for personnel to rush to in-situ processing, have the member of composition characteristic of simple; But this electromagnetic lock also need be driven by control circuit control owing to need energising normally to use.
One Chinese patent application number is that 99125049.4 patent of invention discloses a kind of automatic electronic magnetic door lock, and it comprises first member, second member; First member is provided with main frame electronic loop and electromagnet; Second member is provided with adsorption plate, through main frame electronic circuit device control electromagnet in first member lock and unlock of realizing between first member, second member is adsorbed in the absorption and the releasing of adsorption plate in second member; Said main frame electronic loop includes snubber and microswitch; Snubber one end exposes electromagnet and adsorption plate is relative; The other end and microswitch keep certain clearance, when first member and second member contact with each other, and adsorption plate promotion snubber; Trigger microswitch, start the main frame electronic circuit device.This automatic electronic magnetic door lock needs control circuit to drive and control equally, needs to consume certain electric energy.
Significantly, magnetic force on existing market lock all more or less have an above-mentioned defective, therefore, need a kind of magnetic force lock especially, remedy the problem that the magnetic force on the existing market is latched in.
Summary of the invention
The object of the present invention is to provide a kind of permanent-magnetic lock; Remedy the problem that the magnetic force on the existing market is latched in, have that absorption affinity is big, volume is less relatively, saves energy, effectively increase the service life, receive environment factor to influence little and characteristics such as the scope of application is wider.
The technical problem that the present invention solved can adopt following technical scheme to realize:
A kind of permanent-magnetic lock comprises lock body, it is characterized in that, in said lock body, is provided with the magnetic core that adopts rare earth permanent-magnetic material to process, and the magnetic line of force direction through the said magnetic core of rotation change realizes the absorption and the release of lock body.
Said magnetic core drives said magnetic core through a drive unit and in said lock body, rotates.
Said drive unit connects through a coupling body and said magnetic core, makes drive unit pass through coupling body and drives the magnetic core rotation, with the rotation of more firm control magnetic core.
Said drive unit can be manual driving device or Vidacare corp.
Permanent-magnetic lock of the present invention; The magnetic core of its lock body adopts the Nd-Fe-B rare earth permanent-magnetic material to process; Make full use of the magnetic properties such as remanent magnetism, coercivity, HCJ and magnetic energy product of Nd-Fe-B rare earth permanent-magnetic material; Drive said magnetic core through drive unit and in lock body, rotate, change the magnetic line of force of magnetic core, lockset adhesive when the magnetic line of force is closed; Lockset discharged when the magnetic line of force broke off, and had that absorption affinity is big, volume is less relatively, saves energy, effectively increased the service life, receives environment factor to influence little and characteristics such as the scope of application is wider.
