Marble lock with double opening angles and safety lock structure with same

Abstract

The invention relates to a marble lock, which comprises a lock shell (1), a lock core (2), key holes and marble components, and is characterized in that the key holes are respectively a main key hole (4) and a secondary key hole (6); the marble components are a first marble component (7) and a second marble component (8); the outer periphery surface of the lock core is provided with a step part (21) which is internally depressed to the direction of the center of a circle and extends along the coaxial direction of the lock core (2); under the state that a main key is inserted into the keyhole,the rotation of the main key can drive the lock core to rotate to the first opening angle until a marble (81) in the second marble component to be contacted with the step part in a blocking way, and under the state of inserting a secondary key into the secondary key hole (6), the secondary key promotes the marble in the second marble component to release the contact between the marble and the steppart and lead the simultaneous rotation of the main key and the secondary key to be capable of driving the key to rotate to the second opening angle. The invention also relates to a safety lock structure provided with the marble lock.

Description

technical field [0001] The present invention relates to a tumbler lock, and also relates to a safety lock structure with the aforementioned tumbler lock. Background technique [0002] The traditional tumbler lock structure generally includes a lock case, which is installed in the lock case and the lock cylinder. There are multiple rows of first pin holes arranged at intervals in the lock case. There are key holes in the lock cylinder and interlinked with the multiple rows of key holes and arranged at intervals. The second pinhole, the second pinhole radially penetrates the outer peripheral surface of the lock cylinder, the first pinhole and the second pinhole correspond one by one; in the first pinhole and the second pinhole, springs and at least two pinholes are sequentially arranged from top to bottom. marbles; the shapes of the marbles in the first pinholes and the second pinholes of each group are columns of generally different lengths. The working principle of this kin...

Problems solved by technology

[0004] The above-mentioned various pin locks have such a common feature that the lock cylinder of each pin lock can only be opened within a range of opening angles, that is, the pin lock has only a single locking and opening function, and does not have more additional functions.

[0005] Have again, application has the safe lock structure of traditional tumbler lock, only has conventional locking function, and general safe not only has conventional mechanical lock (as tumbler lock), also has electronic combination lock, and electronic combination lock has forgotten password or damaged. At this time, the emergency opening function is required, and the traditional mechanical lock (such as a tumbler lock) does not have the function of emergency opening of the electronic combination lock, and an additional mechanism is required for emergency opening.
