    • A device for detecting the removal of a cylinder lock used on cars, trunks, etc. when an unjust force is applied to the cylinder lock. The device also detects the locked and unlocked conditions of the cylinder lock. Magnets and magnetic sensor switches are used. A magnetic shield plate shields the flow of magnetic flux between the magnet and the magnetic sensor switch. When an unjust force is applied to the cylinder lock to take off the cylinder lock, the magnetic shield plate will be removed from between the magnet and the magnetic sensor switch, causing the magnet to energize the magnetic sensor switch, thereby detecting the removal of the cylinder lock.In addition, when the cylinder lock is turned by a key, another magnet connected to a rotor of fixed on the cylinder lock approaches either of a pair of magnetic sensor switches, whereby the locked and unlocked conditions of the cylinder lock are detected.
    • 一种用于当不正当的力施加到气缸锁时用于检测在汽车,树干等上使用的气缸锁的拆卸的装置。 该装置还检测气缸锁的锁定和解锁状态。 使用磁铁和磁传感器开关。 磁屏蔽板屏蔽磁体和磁传感器开关之间的磁通量。 当气缸锁上施加不正当的力以取出气缸锁时,磁屏蔽板将从磁体和磁传感器开关之间移除,使磁体对磁传感器开关通电,从而检测到 气缸锁。 此外,当气缸锁被钥匙转动时,连接到固定在气缸锁上的转子的另一个磁体接近一对磁性传感器开关中的任一个,从而检测到气缸锁的锁定和解锁状态。
