Fig. 1 and 2 show an embodiment of the lock cylinder of the invention comprising a lock housing 10, a stationary lock cylinder 20, a lower rotary lock cylinder 30, an upper rotary lock cylinder 40, a pin assembly 50, a driver 60 and a moveable coupling 70. Wherein, the fixed lock core 20 is fixedly arranged in the lock shell 10, the lower rotating lock core 30 is rotatably arranged below the fixed lock core 20, and the upper rotating lock core 40 is rotatably arranged above the fixed lock core 20. The lower rotary cylinder 30 is used to perform an unlocking operation, and the upper rotary cylinder 40 is used to drive the lower rotary cylinder 30 to perform an unlocking operation. The pin assembly 50 is mounted to the upper rotary cylinder core 40 and the fixed cylinder core 20, and an operating end of the pin assembly 50 is exposed from the upper rotary cylinder core 40. The ball assembly 50 includes an aligned state in which the upper rotary cylinder core 40 is rotatable with respect to the fixed cylinder core 20 and a misaligned state in which the ball assembly 50 prevents the upper rotary cylinder core 40 from rotating, in which the operating end is engaged with the key and the operating end is disengaged from the key. The driving member 60 is disposed at the bottom of the upper rotary lock core 40, the movable connecting member 70 is movably disposed on the driving member 60, and the upper rotary lock core 40 can be driven by the driving member 60 to rotate the lower rotary lock core 30. When the key is applied, the movable connecting member 70 is engaged with the lower rotary lock cylinder 30 to connect the driving member 60 with the upper rotary lock cylinder 40 and the lower rotary lock cylinder 30, so that the upper rotary lock cylinder 40 is driven by the driving member 60 to rotate the lower rotary lock cylinder 30. When not subjected to the force of the key, the movable coupling 70 is separated from the lower rotary cylinder core 30, the upper rotary cylinder core 40 idles, and the lower rotary cylinder core 30 is stationary.

By applying the technical scheme of the embodiment, when the unlocking operation is required, the spring assembly 50 is firstly operated to be in an aligned state by matching the key with the operation end of the spring assembly 50. The movable connector 70 is then engaged with the lower rotary cylinder core 30 by the force of the key to connect the upper rotary cylinder core 40 and the driver 60 to the lower rotary cylinder core 30. Thus, the upper rotary cylinder 40 is rotated by turning the key, and the upper rotary cylinder 40 is rotated by the driving member 60 and the movable connecting member 70 to rotate the lower rotary cylinder 30, so that the lower rotary cylinder 30 performs an unlocking operation. If the key does not have or cannot generate an acting force for matching the movable connector with the lower rotary lock cylinder during the unlocking action, although the key can cause the spring assembly 50 to be aligned, the upper rotary lock cylinder 40 can also rotate, but because the movable connector 70 is separated from the lower rotary lock cylinder 30, the driving member 60 cannot drive the lower rotary lock cylinder 30 to rotate through the movable connector 70, the upper rotary lock cylinder 40 idles, and the lower rotary lock cylinder 30 remains static, so that the unlocking action cannot be realized. Thus, even if the code of the bullet assembly 50 is cracked, the unlocking action can not be carried out, and the anti-theft is better realized.

As shown in fig. 1 and 2, in the present embodiment, the lock cylinder further includes a reset member 80, and the reset member 80 is mounted on the movable connecting member 70. The reset member 80 drives the moveable coupling 70 away from the lower rotary lock cylinder 30 when the moveable coupling 70 is not under the force of the key. The release element 80 allows the moveable coupling element 70 to remain disengaged from the lower rotary lock cylinder 30 when not acted upon by a key.

As an alternative embodiment, the driver 60 has a fixed end 61 and a driving end 62, the fixed end 61 is fixedly connected to the bottom of the upper rotary cylinder core 40, the driving end 62 passes through the fixed cylinder core 20 to the lower rotary cylinder core 30, and the moveable connection 70 is arranged on the driving end 62, as shown in fig. 1. When acted by a key, the movable connector 70 is matched with the lower rotating lock cylinder 30; when not under the force of a key, the reset member 80 urges the moveable coupling member 70 away from the lower rotary lock cylinder 30. As shown in fig. 3, in the solution of the present embodiment, a fixed end 61 of the driving member 60 is integrally formed at the bottom of the upper rotary lock cylinder 40, and the upper rotary lock cylinder 40 rotates to drive the driving member 60 to rotate. As an alternative embodiment, the driving member 60 and the upper rotating cylinder 40 may be two relatively independent components, and may be connected together when in use.

In the technical solution of this embodiment, the fixed lock core 20 is matched with the lock case 10 through a limiting part. As shown in fig. 4, a rib is provided on the sidewall of the fixed lock core 20, a groove adapted to the rib is provided on the inner wall of the lock shell 10, and the rotation of the fixed lock core 20 is limited by the cooperation of the rib and the groove.

As shown in fig. 1 and 5, in the present embodiment, a mating groove 31 for mating with the movable connector 70 is formed on the lower rotating lock cylinder 30. In the solution of this embodiment, the driving end 62 of the driving member 60 is inserted into the matching groove 31, and the movable connecting member 70 is matched with the inner wall of the matching groove 31. Preferably, a groove adapted to the movable connector 70 is further formed on an inner wall of the fitting groove 31.

As shown in fig. 1, in the solution of the present embodiment, the movable connector 70 includes a magnetic part 71 and a matching part 72 which are arranged on the driving end 62, and the key is used as a force for magnetic action. As shown in fig. 8 and 11, after the key is inserted, the key brings the bullet assembly 50 into alignment. As shown in fig. 9, the magnetic action of the key attracts the magnetic member 71. When receiving magnetic action, magnetic part 71 moves on driving end 62, and drive cooperation part 72 stretches out from driving end 62 and cooperates with the inner wall butt of cooperation groove 31, just so can be connected driving piece 60 and last rotation lock courage 40 and lower rotation lock courage 30 through mobile connector 70, rotate and rotate lock courage 40 and just can drive down rotation lock courage 30 and carry out the action of unblanking.

As shown in fig. 9 and 10, as an alternative embodiment, the matching component 72 is a steel ball, a mounting hole 621 for mounting the steel ball is opened on the driving end 62, and an arc-shaped groove 711 matched with the steel ball is formed on the magnetic component 71 at a position corresponding to the mounting hole 621. When the magnetic member 71 is not magnetically acted, the steel ball is fitted into the arc-shaped groove 711 and separated from the inner wall of the fitting groove 31. In this process, the restoring member 80 keeps the magnetic member 71 in this state. When the magnetic member 71 is magnetically acted, the magnetic member 71 moves upward, and the arc-shaped groove 711 of the magnetic member 71 is misaligned with respect to the mounting hole 621. The steel ball is pulled out from the arc-shaped groove 711 and extends out from the mounting hole 621 towards the matching groove 31, and the part of the magnetic component 71 adjacent to the arc-shaped groove 711 presses the steel ball to be abutted and matched with the inner wall of the matching groove 31. This connects the movable connecting part 70 to the fitting groove 31, and when the upper rotary cylinder 40 is rotated, the lower rotary cylinder 30 is rotated. As shown in fig. 5, the grooves on the inner wall of the matching groove 31, which are matched with the steel ball, can enhance the connection effect between the steel ball and the inner wall of the matching groove 31. Meanwhile, if the magnetic component 71 is not magnetically acted, the magnetic component 71 will return to the position where the arc-shaped groove 711 is opposite to the mounting hole 621 under the action of the reset member 80, and if the driving member 60 is rotated, the steel ball will return to the arc-shaped groove 711 under the action of the inner wall of the matching groove 31 because the steel ball is no longer supported by the magnetic component 71. As a preferred embodiment, there are a plurality of steel balls, a plurality of mounting holes 621 corresponding to the steel balls are formed on the side wall of the driving member 60, and a plurality of arc-shaped grooves 711 corresponding to the steel balls are also formed on the magnetic member 71, so that a better connection effect can be achieved by the plurality of steel balls.

As other alternative embodiments, the engaging member 72 and the magnetic member 71 may be in a wedge-shaped engaging structure, and any engaging structure that can convert the vertical movement into the horizontal movement is possible.
