Multiplex anti-theft lock

[0025] The present invention is achieved through the following technical solutions:

[0026] Lock cylinder structure reference figure 1 and figure 2 , comprising a front lock cylinder 1 and a rotatable pin 2. The front lock core 1 is divided into 8 drilled holes in two rows up and down and 8 rotatable angle pins 2 installed in the drilled holes. The inner diameter of the drilled holes is mm, the outer diameter of pin 2 is mm, the distance between any marble in the upper row and the virtual center of the adjacent upper row of marbles is 6mm, and the distance H1 between any marble in the upper row and the virtual center of the adjacent lower row of marbles is 4mm. The distance H2 between the virtual center of an upper row of pins parallel to the axis of lock cylinder 1 and the line passing through the virtual center of the lower row of pins adjacent to the pin and parallel to the axis of lock cylinder 1 is 2.5mm .

[0028] Structural reference of the key matched with the lock cylinder structure image 3 , including a spoon body 11 and a pit 12. What is set on the spoon body 11 is divided into 8 pits 12 corresponding to the upper end shape of the marble 2 of the rotatable angle in two rows up and down, and the inner diameter of the pit 12 is mm, the distance between any one pit in the upper row and the virtual center of the adjacent upper row of pits is 6mm, the distance between any one pit in the upper row and the virtual center of the adjacent lower row of pits is 4mm, Between a straight line passing through the virtual center of any upper row of pits and parallel to the longitudinal centerline of the spoon body and a straight line passing through the virtual center of the lower row of pits adjacent to the pit and parallel to the longitudinal centerline of the spoon body The distance is 2.5mm.

[0029] When the user inserts the correct key, the slot of the key will push the rotatable ...

[0031] refer to Figure 4-Figure 6 , including a front lock cylinder 1, a locking block spring 5, a rotatable angle pin 2, a locking block 4, a lock cylinder sleeve 5, and a slot 6.

[0032] Others are the same as embodiment 1, except that there is a lock core cover 3 with a circular through hole, a front lock core 1 installed in the lock core cover 3 circular through holes, 8 marbles 2 installed on the front lock core 1, The inner wall of the circular through hole of the lock core sleeve 3 is along the X axis, with the axis of the circular through hole as the origin, and a slot 31 is respectively arranged at 0° and 180° on the Y-Z plane, along the X axis, before The axis of the lock core 1 is the origin, and two lock blocks 4 and lock block springs 5 ​​are set at 0° on the Y-Z plane to pass through the front lock core 1 and cooperate with two marbles 2 respectively; The locking block 4 and the locking block spring 5 which are matched with the front lock cylinder 1 and the tw...
