The invention relates to a lock device, having a first connecting module and a second connecting module. The first connecting module can here be arranged in a closing direction on the second connecting module and is mechanically catch-lockingly engaged in a closing position with the second connecting module, and the first connecting module can be detached from the second connecting module by a movement of the first connecting module or of a part of the first connecting module in an opening direction, which differs from the closing direction. Here, a locking device (7; 9, 9a-f) is provided to prevent a movement of the first connecting module (1) or of the part (1a) of the first connecting module (1) in the opening direction (Y), when the first connecting module (1) and the second connecting module (2) are positioned in the closing position, wherein the locking device (7, 9, 9a-f; 100, 101, 102; 206, 207) can be unlocked to move the first connecting module (1) or the part (1a) of the first connecting module (1) in the opening direction (Y).

A combination lock can be operated manually via the manipulation of rotatable dials and by way of a key, such as an electronic key. The lock includes one or more rotatable dials each having multiple indicia disposed thereon. Rotation of the rotatable dials to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in in the unlocked position. The lock further includes a knob assembly that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a latched position and a second position in which the lock is in an unlatched position. The combination lock may automatically scramble the positions of the dials upon opening for security purposes.

A detachable lock device with a combination lock includes a lower clamping plate, a locking assembly, a connecting assembly and an upper clamping plate. The upper clamping plate has a clamping position for clamping a zipper and an unclamping position for releasing the zipper, and the upper clamping plate is connected to the lower clamping plate through the connecting assembly, so that the upper clamping plate is locked at the clamping position relative to the lower clamping plate. The locking assembly has a rotatable encircling member, a locking area for locking a zipper slider, the zipper slider is locked in the locking area or the locking area is opened by rotating the encircling member, and the locking assembly includes a mechanical combination lock for locking or unlocking the encircling member. The detachable lock device has easy disassembly and assembly and simple structure.
