Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further.
The memory type key based on magneto discoloration principle as shown in Figures 1 to 4, comprises the lock body and the associated key 1 be made up of key handle, the shank of the key and key that are made up of lock core sleeve and lock core; Described lock core is assemblied in lock core sleeve, described lock core comprises outer lock core 16, be located at the internal cylinder 2 of outer lock core 16 inside, be located at lock core plectrum 13 and lock core moving tooth 14 that internal cylinder 2 end is connected with internal cylinder 2, described internal cylinder 2 is provided with interior marble hole, hole is built with interior pellet 3, outer lock core 16 is corresponding thereto provided with outer marble hole, outer pellet 4 is provided with in hole, outer pellet 4 upper end is provided with tack spring 5, tack spring 5 end is provided with and flat plays end socket 11, is describedly provided with the magnetic strength color lump 12 be made up of magneto discoloration material on the key.
Outer lock core is embedding near keyhole one end place the magnetizing assembly be made up of U magnet 9, magnet end socket 10, and described U magnet 9 liang of magnetic pole end faces are concordant with outer lock core 16 inner cylinder face; Internal cylinder 2 is provided with guide and limit groove 15 near keyhole one end, on outer lock core 16, near keyhole one end, corresponding internal cylinder guide and limit groove 15 place is provided with guide and limit pin, described guide and limit pin can slide in guide and limit groove 15, thus drive magnetic strength color lump 12 on the key to move axially, when internal cylinder 2 " indentation ", another magnetic pole is aimed at when magnetic strength color lump 12 aims at a magnetic pole, " protrusion " of U magnet 9, magnetic strength color lump 12 is subject to the magnetization of magnetic pole and shows different colours, the open and-shut mode of instruction door lock.
As shown in Figure 2, guide and limit groove 15 is made up of with the skewed slot 15-3 being connected interior outer ring groove inner side annular groove 15-1, outside annular groove 15-2 near keyhole one end for being located in internal cylinder 2.
As shown in Figure 1, guide and limit pin is made up of the pellet 6 that leads, guide spring 7, guiding end socket 8, and guiding pellet 6 can slide in guide and limit groove.
As shown in Figure 2, inner side annular groove 15-1, the gradual change in 360 ° of the outside annular groove 15-2 depth, its joint (annular groove Origin And Destination intersection) place has 1mm drop (step), described inner side annular groove 15-1 is contrary with annular groove 15-2 depth gradual change direction, outside, its joint staggers 22.5 °, described skewed slot 15-3 starting point is located at annular groove 15-2 joint, outside, terminal is located at annular groove 15-1 joint, inner side, without gradual change and drop between its Origin And Destination, the depth is identical with annular groove bosom, and the incline direction of described skewed slot 15-3 is consistent with the direction of rotation of unblanking or shut.
Just to the position of magnetic strength color lump 12 on the key in described internal cylinder 2, embed an iron leg magnetic material as magnetic conduction, to strengthen the magnetization to magnetic strength color lump.
Described magnetic strength color lump 12 is magneto discoloration colloidal sol.
Described magneto discoloration colloidal sol is tri-iron tetroxide colloidal sol.
During locking state internal cylinder inside contract, unlocking condition time evagination, " inside contracting " position is concordant with outer lock core outer face and lock housing plane.
Operating principle of the present invention:
Final purpose of the present invention is: allow key remember the state of locking.Below set forth its structural principle.
Memory effect relies on and embeds the permanent magnet in outer lock core and the magnetic strength color lump realization made from magneto discoloration material on the key.
1, structure:
The U-shaped magnet 9 that outer lock core 16 is embedded in, its two magnetic poles end face is concordant with outer lock core 16 inner cylinder face.Can keep " being adjacent to " relation with internal cylinder 2 like this.Key 1 embeds one piece of magnetic strength color lump 12, just to the position of magnetic strength color lump 12 on key 1 in internal cylinder 2, then embeds an iron leg magnetic material.Here mainly play magnetic conduction effect, and then strengthen the magnetization to magnetic strength color lump.
2, principle:
On the basis of said structure, as long as when internal cylinder 2 " indentation ", when allowing magnetic strength color lump 12 aim at a magnetic pole, " protrusion " of U magnet 9, aim at another magnetic pole.Namely magnetic strength color lump 12 is allowed at locking state and unlocking condition by the magnetic field magnetisation of two different directions.Result when key is extracted, as long as look at that the color relation of magnetic strength color lump can know what state lock core sentences.
It should be noted that: magneto discoloration effect can't be permanent, just in time only need this short-term memory function here.
Specific works process.
(1) to lock process:
Lock core turns clockwise, and the depth due to groove is from shallow to deep, and guiding pellet can be slided into skewed slot by stopping at " joint " place, and this just forces lock core to do axial slip to the inside.Once slip into inner side annular groove, when lock core continues to turn clockwise, the depth due to groove is by dark and shallow, again runs into " joint " after 360 °, only can produce one " falling ", still can accessiblely slide.This is just two grades (circles), many grades (circles) of third gear (circle) safe-guard door lock leave leeway.
(2) to unblank process:
Lock core is rotated counterclockwise, and the depth due to groove is also from shallow to deep, and guiding pellet can be slided into skewed slot by stopping equally at " joint ", forces lock core to do axial slip laterally.Once slip into outside annular groove, when lock core continues to be rotated counterclockwise, the depth due to groove is by dark and shallow, again runs into " joint " after 360 °, only can produce one " falling ", still can accessiblely slide.
Note, during locking state lock core inside contract, unlocking condition time evagination, be location of the present invention advise.And advise so-called " inside contracting " position that preferably lock core outer face is concordant with lock housing plane, position.Lock body in view of general safe-guard door lock has lock nut to hide, therefore the lock core protruded does not affect outward appearance.
To sum up, the present invention accomplishes the end in view.
