Abstract: The present disclosure relates to the technical field of lock, especially to the lock device for locking the sliding door. The lock device comprises a first lock portion and a transmission portion. The transmission portion may move along relative to the first lock portion a predetermined path, so that the transmission portion may bring the sliding door to move along the predetermined path to open or close the sliding door. The transmission portion has a plurality of successively arranged mating portions for locking with the first lock portion. The first lock portion has a first position in which the first lock portion is locked with the transmission portion and a second position in which the first lock portion is released from the transmission portion. The transmission portion may be locked in different positions along the predetermined path by matching the first lock portion (110) with different mating portions, so that the sliding door can be locked in different positions. Through the technical solution mentioned above, the sliding door may be locked not only in a fully open position or a fully closed position of the sliding door, but also in any partly-open position of the sliding door, so that the sliding door maybe locked in the partly-open state stably.
