On the basis, the elastic mechanism is an elastic arm which is integrally formed with the swing frame and elastically presses the lock shell.

Adopt the utility model discloses the beneficial effect who brings: under the action of the elastic mechanism, the swing frame keeps swinging away from the clutch gear ring state, namely the elastic clamping arm is not inserted into the clamping groove of the clutch gear ring, and the coded lock can be normally used. When the password can not be confirmed, the administrator can open the primary-secondary lock by using the primary key at the moment, open the storage cabinet, insert the ejector key from the through hole of the lock shell to push the ejector seat to swing to the clutch toothed ring, so that the elastic clamping arm is elastically deformed and tightly pressed on the peripheral wall of the clutch toothed ring, then rotate the password wheel to drive the clutch toothed ring to rotate, when the clamping groove of the clutch toothed ring rotates to the unlocking position, the elastic clamping arm which is elastically deformed is restored to be inserted into and clamps the clamping groove, and the number exposed on the password wheel at the moment is the unlocking password. Therefore, the utility model discloses the lock has can retrieve the password function, and the system management of being convenient for very much uses.

Detailed Description

As shown in fig. 1-5, a lock with a function of retrieving a password comprises a password lock assembly 1, a knob 2 locked by the password lock assembly 1, a key lock assembly 3 sleeved in the knob 2 to lock the knob 2, and a lock tongue 4 fixed with a core shaft 3.1 of the key lock assembly 3, wherein the password lock assembly 1 is provided with a core shaft 1.1, a clutch toothed ring 1.2 sleeved on the core shaft 1.1, and a password wheel 1.3 sleeved on the clutch toothed ring 1.2. Generally, the combination lock adopts three groups of codes. The mandrel 1.1 is provided with three groups of convex keys (common structures are not marked in the figure) which are axially arranged at intervals, a key groove is formed on the inner wall of each clutch toothed ring 1.2, the mandrel 1.1 can axially move only when the clutch toothed rings 1.2 rotate until the key grooves are opposite to the convex keys, and the rotation of the knob 2 at the end part of the mandrel 1.1 is controlled, so that the rotation of the lock tongue 4 is controlled. Under the state of locking, dabber 1.1 is unable to remove, and the tip of dabber 1.1 inserts the recess 2.1 of knob 2 lateral wall for can't rotate knob 2 and unblank. In the unlocked state, the spindle 1.1 can be moved axially, so that the rotatable knob 2 is unlocked. In a normal state, the key lock is in a locked state, and the knob 2 is combined and linked with the whole key lock assembly 3. When the key lock is unlocked by a master key, the key can be rotated to rotate the core shaft 3.1 and the bolt 4
