The specific embodiment
Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not to be used to limit the utility model.
As Fig. 2-shown in Figure 4, the utility model comprises lock core and key, described lock core is located at the outer outer core 2 of inner core by inner core 1 and turning set and is formed, the inner core 1 of lock core is provided with axial, lockhole 3 for the key insertion, its side face and outer in-core wall fluid-tight engagement, described lock core is provided with its outer core of connection and inner core, two or more, pellet shot from a slingshot hole 4 radially, the ecto-entad magnetic bead 5 that is slidingly connected successively in each pellet shot from a slingshot hole, an insulation hoodle 6, a spring 7, described insulation hoodle 6 flexibly connects with a magnetic pole of magnetic bead 5, described spring 7 one ends prop up the nearly lockhole end in pellet shot from a slingshot hole 4, and the other end props up the insulation hoodle: have at least two magnetic beads 5 in the pellet shot from a slingshot hole 4 different with the weight sum of insulation hoodle 6.
As shown in Figure 5, be provided with voltage-stabilized power supply and a plurality of solenoid 8 in the described lock core, described solenoid is corresponding one by one with the pellet shot from a slingshot hole, and each solenoid is located at an inside side of its nearly lockhole end in corresponding pellet shot from a slingshot hole, and coaxial with this pellet shot from a slingshot hole.Described lockhole 3 inwalls are provided with a plurality of contacts 301, mutually insulated between each contact, and each solenoid 8 corresponding contact 301, other contact is connected to the negative pole of voltage-stabilized power supply.Each solenoid all has two interfaces, and one of them interface is connected to the corresponding contact on the lockhole inwall, and another interface is connected to the positive pole of voltage-stabilized power supply.
As shown in Figure 7, described key is made up of a plurality of miniature resistance 9, shell 10 and insulation lever 11.Described shell 10 shapes size is corresponding with lockhole 3, and its external surface is provided with and each contact 301 corresponding contact of lockhole 3 inwalls, mutually insulated between each contact.Described insulation lever and shell are affixed.Described miniature resistance is located in the shell, and corresponding one by one with solenoid 8, and each miniature resistance one is connected to and the corresponding contact in the contact that is connected the voltage-stabilized power supply negative pole, and the other end is connected to and connects its corresponding contact in corresponding solenoidal contact.
Spring in the described pellet shot from a slingshot hole 4 is a light spring.The miniature resistance 9 of described key is Chip-R.The shell 10 of described key is a metal shell.
As shown in Figure 2, under normal condition, magnetic bead in the stand hole and insulation hoodle are subjected to the influence of gravity and spring force, are still in the pellet shot from a slingshot hole, and instrumentation that inner core and outer core are located in the pellet shot from a slingshot hole and portion are insulated hoodle and block, and this moment, inner core can't rotate.
As Fig. 3, shown in Figure 6, after in lockhole, inserting correct key, the contact of key external surface contacts with each contact of lockhole inwall, thereby each small resistor in the key is inserted make in the solenoidal circuit each solenoid conducting, the electric current that passes through on each solenoid makes each solenoid produce the electromagnetic field of suitable field intensity respectively, and the magnetic bead that promotes in its corresponding pellet shot from a slingshot hole by electromagnetic field repulsion is subjected to displacement, magnetic bead and insulation hoodle are static when electromagnetic field repulsion and spring force reach balance, magnetic bead in each pellet shot from a slingshot hole and insulation hoodle joint just in time are in the junction surface of inner core and outer core, this moment, screw key can drive the inner core rotation, thereby realized unblanking; Each solenoid cuts off the power supply after extracting key, makes magnetic field diminishes, the elastic force of spring make magnetic bead and insulation hoodle return back to original state.
After in lockhole, inserting wrong key, owing to have at least a corresponding solenoidal correct resistance of small resistor not match in the key with it, therefore can't make this solenoid produce the electromagnetic field of suitable field intensity, make the junction surface that magnetic bead in the pairing pellet shot from a slingshot of this solenoid hole and insulation hoodle joint are not in inner core and outer core, making inner core be stuck can't rotate, and can't open lockset.
