【Specific embodiment】
Operation principle of the invention is first simply described with reference to accompanying drawing：
Fig. 2 is to be not inserted into the internal structure state diagram of key, effect of the magnetic pellet 31 in the elastic force of spring 41 in lock gall
Be in simultaneously down on the first lower marble hole 121 and first in marble hole 111 (i.e. magnetic pellet can block lock housing and lock gall, it is impossible to
Open), and the lower end of magnetic pellet 31 is completely in the first lower marble hole 121, now cannot be with instrument from keyhole 122
Instigate magnetic pellet 31 make the upper surface of magnetic pellet 31 just with the flush with outer surface of lock gall 12, i.e., cannot use instrument from key
Magnetic pellet is instigateeed in hole and unlocked, improve security of the invention.
Fig. 3 is the internal structure state diagram of the key of inserting error in lock gall, and magnetic pellet 31 is inhaled in magnetic bead 22 on the key
It is completely in the presence of gravitation in the first lower marble hole 121, and the lower surface of magnetic pellet 31 contacts with the outer surface of magnetic bead 22,
Because using the key of mistake, now the second pellet 32 is adsorbed in the presence of magnetic force and made in the upper surface of magnetic pellet 31
(i.e. the second pellet 32 can block lock housing in marble hole 111 on the first lower marble hole 121 and first simultaneously to obtain the second pellet 32
And lock gall, it is impossible to unlock).The key of mistake also has another situation, that is, magnetic pellet is in the first lower marble hole simultaneously
On 121 and first in marble hole 111, such case is not described in detail herein with reference to the situation and Fig. 2 that are not inserted into key.
Fig. 4 is to insert the internal structure state diagram of correct key in lock gall；Magnetic pellet 31 attracts in magnetic bead 22 on the key
It is completely in the presence of power in the first lower marble hole 121, the lower surface of magnetic pellet 31 contacts with the outer surface of magnetic bead 22, and magnetic
Inhale pellet 31 upper surface just with the flush with outer surface of lock gall 12, now by key can drive lock gall with respect to lock housing turn
It is dynamic, realize unlocking.
Embodiments of the present invention are elaborated below in conjunction with the accompanying drawings.
Embodiment 1：
As shown in Figures 1 to 4, a kind of key in the present embodiment, including key body 2, use is provided with key body 2
In the magnetic bead 22 for driving the motion of the magnetic pellet in lock.
Further, key body 2 is provided with bullet groove 21, and described magnetic bead 22 is arranged in bullet groove 21.
As shown in Figures 1 to 4, the lock that a kind of anti-technology in the present embodiment is opened, it is supporting with key recited above to make
With including lock body 1, described lock body 1 includes lock housing 11 and the lock gall 12 that can be rotated in lock housing 11, is set on described lock gall 12
There is the first lower marble hole 121, described lock housing 11 is provided with and marble hole 111, institute on the first lower marble hole 121 corresponding first
The lock gall 12 stated is provided with and is communicated with the first lower marble hole 121 and for the keyhole 122 of key insertion, first time described pellet
Be provided with hole 121 it is movable snap in marble hole 111 and the magnetic pellet 31 that can be driven by magnetic bead 22 on the key on first, it is described
The first lower marble hole 121 in be additionally provided with the return unit 4 for driving magnetic pellet 31 to reset；After key inserts keyhole 122, magnetic
Inhaling pellet 31 makes magnetic pellet 31 depart from marble hole 111 on first in the presence of the magnetic force of magnetic bead 22 and realizes unlocking.The present invention
The lock opened of a kind of anti-technology, when being not inserted into key, magnetic pellet 3 is in the presence of the return unit 4 simultaneously under first
(i.e. magnetic pellet 3 is hidden in marble hole on the first lower marble hole 121 and first in marble hole 111 on marble hole 121 and first
In 111), after only inserting keyhole 122 with the key of matching, magnetic pellet 3 departs under the attraction of magnetic bead 22 on the key
Marble hole 111 could unlock on first, it is to avoid people instigate magnetic bullet in the case of without correct key using instrument
Son and will lock open, greatly improve the security of lock.
The bottom surface of keyhole 122 to the upper end of the first lower marble hole 121 distance be L, the upper surface of magnetic bead 22 to key bottom
Distance is A, and the length of magnetic pellet 31 is B；Wherein L, A, B meet：L=A+B.Therefore L, A, B have very many combinations, while
The magnetic pellet 31 of multigroup different size, magnetic bead 22 can also be set to improve the complexity of lock, the present invention is further improved
The difficulty being cracked.
The situation that such scheme can prevent people from instigateeing magnetic pellet from keyhole and unlock, as people are to the present invention
Further appreciate that, people can using the suitable attraction magnetic pellet of thickness make magnetic pellet 31 depart from first on pellet
Hole 111 (i.e. magnetic pellet 31 can not block lock housing and lock gall) and unlock, for this situation, marble hole on of the invention first
The second pellet 32 that can be slided in marble hole 111 on the first lower marble hole 121 and first with magnetic pellet 31 is provided with 111.
Even if people make magnetic pellet 31 be completely in the first lower marble hole 121 using the suitable attraction magnetic pellet 31 of thickness
Interior, the second pellet 32 makes the second pellet 32 into the first lower marble hole 121 simultaneously in first time bullet with magnetic pellet 31
In sub-aperture 121 and first in marble hole 111 (i.e. the second pellet 32 can block lock housing and lock gall, it is impossible to unlock), only using complete
The key of total correctness can just make magnetic pellet 31 in the presence of the attraction of magnetic bead 22 on the key, the lower surface of magnetic pellet 31 with
The outer surface of magnetic bead 22 contact, and magnetic pellet 31 upper surface just with the flush with outer surface of lock gall 12, could realize unlocking, more
The difficulty being cracked of the invention is further improved, security of the invention is improved.
Second pellet 32 can be made into integration using magnetic material.It is equally possible that being set in marble hole 111 on first
Follower spring (not shown) is put to drive the second pellet 32 as magnetic pellet 31 is moved.
Return unit 4 is the spring 41 for driving magnetic pellet 31 to be resetted away from keyhole 122, and magnetic pellet 31 is provided with platform
Shoulder 311, described spring 41 is enclosed within magnetic pellet 31, and the first described lower marble hole 121 is provided with for support spring 41
Step 1211.
Of particular note is that：Technical key point is applied on traditional spring lock can also be reached and the present invention
Identical effect, i.e., using the one or more groups of magnetic beads in the present invention, magnetic pellet, the second pellet combination；Others are used
The part of traditional spring lock, i.e.,：Lock gall 12 is provided with the second lower marble hole 126, described lock housing 11 be provided with second under
Marble hole 128 on marble hole 126 corresponding second, bullet is provided with the second described lower marble hole 126 and second in marble hole 128
Pearl component 6, is provided with the back-moving spring for driving the reset of hoodle component 6 in marble hole 128 on described second.
Embodiment 2：
As shown in Figures 5 to 9, this implementation with implement 1 difference be：The structure shape of magnetic pellet 31 and return unit 4
Formula is different, and return unit 4 is the spring 41 for driving magnetic pellet 31 to be resetted away from keyhole 122, in magnetic pellet 31 and vertically
Its direction of motion is provided with spring mounting hole 319, and described spring 41 is arranged in spring mounting hole 319, first time described bullet
Sub-aperture 121 is provided with raised 1218 for support spring 41.
