Specific embodiment
Come to be described further the present invention with reference to the accompanying drawings and examples.
The memory-type key based on magneto discoloration principle as shown in Figures 1 to 4, including be made up of lock core sleeve and lock core
Lock body and the associated key 1 being made up of key handle, the shank of the key and key；The lock core is assemblied in lock core sleeve,
The lock core includes outer lock core 16, the internal cylinder 2 inside outer lock core 16, is connected with internal cylinder 2 located at the end of internal cylinder 2
Lock core plectrum 13 and lock core moving tooth 14, the internal cylinder 2 are provided with interior marble hole, hole built with interior pellet 3, corresponding thereto outer
Lock core 16 is provided with outer marble hole, and outer pellet 4 is provided with hole, and the upper end of outer pellet 4 is provided with tack spring 5, and the end of tack spring 5 sets
There is flat bullet end socket 11, it is described to be provided with the magnetic strength color lump 12 being made up of magneto discoloration material on the key.
Outer lock core is in the magnetizing assembly being made up of U magnet 9, magnet end socket 10 near the insertion of keyhole end, the U
9 liang of magnetic pole end faces of shape magnet are concordant with the inner cylinder face of outer lock core 16；In internal cylinder 2 guide and limit is provided near keyhole one end
Groove 15, guide and limit pin is provided with outer lock core 16 at the corresponding internal cylinder guide and limit groove 15 in keyhole one end, described to lead
Can be slided in guide and limit groove 15 to spacer pin, so as to drive magnetic strength color lump 12 on the key to move axially, work as internal lock
During core 2 " indentation ", magnetic strength color lump 12 is directed at another magnetic pole, magnetic strength color lump when being directed at a magnetic pole, " protrusion " of U magnet 9
12 are shown different colours by the magnetization of magnetic pole, indicate the open and-shut mode of door lock.
As shown in Fig. 2 guide and limit groove 15 is by inner side annular groove 15-1, outer in internal cylinder 2 near keyhole one end
The skewed slot 15-3 compositions of side ring groove 15-2 and the inside and outside side ring groove of connection.
As shown in figure 1, guide and limit pin by guiding pellet 6, guide spring 7, be oriented to end socket 8 and constitute, being oriented to pellet 6 can be
Slided in guide and limit groove.
As shown in Fig. 2 inner side annular groove 15-1, outside annular groove 15-2 depths gradual change in 360 °, its joint（Annular groove starting point with
Terminal intersection）Place has 1mm drops (step), the inner side annular groove 15-1 and outside annular groove 15-2 depth gradual changes direction phase
Instead, its joint is staggered 22.5 °, and the skewed slot 15-3 starting points are located at outside annular groove 15-2 joints, and terminal is located at inner side annular groove
15-1 joints, without gradual change and drop between its Origin And Destination, the depth is identical with annular groove bosom, and the skewed slot 15-3's inclines
Tilted direction is consistent with the direction of rotation unlocked or shut.
Just to the position of magnetic strength color lump 12 on the key in the internal cylinder 2, an embedded iron leg magnetic material as magnetic conduction, with
Strengthen the magnetization to magnetic strength color lump.
The magnetic strength color lump 12 is magneto discoloration colloidal sol.
The magneto discoloration colloidal sol is ferroso-ferric oxide colloidal sol.
During locking state internal cylinder inside contract, unlocking condition when evagination, " inside contracting " position and outer lock core outer face and lock housing are flat
Face is concordant.
Operation principle of the invention：
Final purpose of the invention is：Key is allowed to remember the state of lock.Its structural principle set forth below.
Memory effect is by the permanent magnet and the magnetic strength color being made of magneto discoloration material on the key in embedded outer lock core
Block is realized.
1, structure：
The U-shaped magnet 9 that outer lock core 16 is embedded in, its two magnetic poles end face is concordant with the inner cylinder face of outer lock core 16.So can be with
Internal cylinder 2 keeps " being adjacent to " relation.Embedded one piece of magnetic strength color lump 12 on key 1, just to magnetic strength color lump on key 1 in internal cylinder 2
12 position, then an embedded iron leg magnetic material.Here it is main to play magnetic conduction, and then strengthen the magnetization work to magnetic strength color lump
With.
2, principle：
On the basis of said structure, as long as at internal cylinder 2 " indentation ", allowing magnetic strength color lump 12 to be directed at the one of U magnet 9
Another magnetic pole is directed at when individual magnetic pole, " protrusion ".Allow magnetic strength color lump 12 in locking state and unlocking condition by two not Tongfangs
To magnetic field magnetize.Result is when key is extracted, as long as looking at that the color of magnetic strength color lump just can know that what state lock core sentences.
It should be noted that：Magneto discoloration effect be can't be permanent, and this short-term memory function is just only needed to herein.
Specific work process.
(1) lock process：
Lock core turns clockwise, because the depth of groove is that from shallow to deep, being oriented to pellet can be blocked and slide at " joint " place
Enter skewed slot, this just forces lock core to do axial slip to inner side.Once inner side annular groove is slipped into, when lock core continues to turn clockwise, by
It is, by deep and shallow, to run into " joint " after 360 ° again in the depth of groove, only can produces one " falling ", accessible can still slides.
This is just two grades (circle), the multi gear (circle) of third gear (circle) safe-guard door lock leaves leeway.
(2) unlocking process：
Lock core rotate counterclockwise, because the depth of groove is also that from shallow to deep, being oriented to pellet can equally be blocked at " joint "
And skewed slot is slided into, force lock core to do axial slip laterally.Once outside annular groove is slipped into, when lock core continues rotate counterclockwise, by
It is, by deep and shallow, to run into " joint " after 360 ° again in the depth of groove, only can produces one " falling ", accessible can still slides.
Note, during locking state lock core inside contract, unlocking condition when evagination, be it is of the invention positioning suggestion.And suggestion is so-called
" inside contracting " position be preferably the lock core outer face position concordant with lock housing plane.In view of having on the lock body of general safe-guard door lock
Lock nut is covered, therefore the lock core of protrusion has no effect on outward appearance.
To sum up, the present invention accomplishes the end in view.
