Magnetic coding, increases anti-theft.
Locking principle:
Lower mother pearl 141 is connected on the cascaded surface in upper female hole of bead 121 under the spring-force driven dual of female pearl spring 145, upper mother pearl 143
It is fastened between outer lock gall 120 and interior lock gall 110, so that outer lock gall 120 is cannoted rotate relative to each other with interior lock gall 110；And sub- pearl 142
It is being fastened under the spring-force driven dual of sub- pearl spring 144 between upper female pearl 143 and lower female pearl 141, is making female pearl 143 and lower female pearl
141 cannot rotate relative to each other；
Magnetic marble 151 is connected to 113 bottom of magnetic marble hole under the spring-force driven dual of marble spring 153, and lower pellet 152 is fastened on
Between outer lock gall 120 and interior lock gall 110, cannot rotate relative to each other outer lock gall 120 with interior lock gall 110；
Lower locking pin 161 is connected to the cascaded surface in lower locking pin hole 114 under the spring-force driven dual of locking pin spring 163
On, upper locking pin 162 is fastened between outer lock gall 120 and interior lock gall 110, makes outer lock gall 120 can not be opposite with interior lock gall 110
Rotation；
Therefore, by limiting the relative rotation between outer lock gall and interior lock gall from three directions, it may make magnetic force primary and secondary bead lock core
In blocking.
Unlock principle:
The unlocking portion 240 for solving lock key 200 is inserted into keyhole 111, the tapered lower end face of lower mother pearl 141 is connected to primary and secondary
In pearl tooth socket 210, the bearing surface of female pearl 143 upper at this time and lower female pearl 141 is just in the boundary of interior lock gall 110 and outer lock gall 120
On face；Meanwhile sub- pearl 142 overcomes the spring force of sub- pearl spring 144 to move downward under the magnetic attraction effect of magnet steel 220, sub- pearl
142 tapered lower end face is connected to the end face of magnet steel 220, and sub- pearl 144 is just off the circle in the middle part of 143 lower surface of upper female pearl at this time
Hole B1431 is no longer fastened between female pearl 143 and lower female pearl 141, and phase can occur for female pearl 143 upper at this time and lower female pearl 141
To rotation, interior lock gall 110 and outer lock gall 120 can relatively rotate；
Since magnet steel 220 is identical as the magnetic polarity of magnetic marble 151, magnetic marble 151 overcomes pellet under the magneticaction of magnet steel 220
The spring force of spring 153 pushes lower pellet 152 to move downward, at this time the bearing surface of magnetic marble 151 and lower pellet 152 just including
On the interface of lock gall 110 and outer lock gall 120, interior lock gall 110 and outer lock gall 120 can relatively rotate；
The tapered lower end face of lower locking pin 161 is connected in the solution locked groove 230 in unlocking portion 240, at this time upper locking pin 162 with
The bearing surface of lower locking pin 161 is just on the interface of interior lock gall 110 and outer lock gall 120, interior lock gall 110 and outer lock gall
120 can relatively rotate；
Therefore, lock key is solved by insertion, realizes magnetic force primary and secondary pearl component, magnetic coding pellet component and locking pin component
Unlock, keeps magnetic force primary and secondary bead lock core in the unlocked state.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, is all covered by the present invention.
