Detailed Description

As shown in fig. 1 and 2, the double-head management lock includes a lock housing 1, a bolt 2 and a lock cylinder, wherein the bolt 2 is connected to a transmission member 5, and the bolt 2 moves back and forth by being driven by the transmission member 5, so as to achieve locking or unlocking, which are the prior art.

In order to realize the two-stage unblock, the utility model discloses a lock core is connected with the transmission of driving medium 5 including one-level lock core 4 and second grade lock core 4, wherein second grade lock core 4, and through the drive of second grade lock core 4, driving medium 5 just can remove to drive spring bolt 2 and remove. Rotationally install the locating part 6 that is used for restricting driving medium 5 to move back the unblock in lock shell 1, one-level lock core 3 is dialled with the one-level and is connected 30, and the one-level is dialled 30 and can be stirred locating part 6 and rotate, and locating part 6 is connected with piece 7 that resets (piece 7 is reset spring or reset torsion spring), and through the drive of one-level lock core 3, the one-level is dialled 30 and can be stirred locating part 6 and rotate, and so locating part 6 just no longer restricts driving medium 5 and moves back.

The specific unlocking principle is as follows: when the safety door is locked, the transmission piece 5 is positioned on the left side (as the left direction in fig. 1), the bolt 2 is positioned outside the lock shell 1, the limiting piece 6 limits the transmission piece 5 under the action of the reset piece 7, and in this state, even if the secondary lock cylinder 4 is unlocked, the transmission piece 5 cannot move towards the right side due to the limitation of the limiting piece 6, so that the bolt 2 cannot move back to be unlocked. The second-level key corresponding to the second-level lock cylinder 4 is managed by a foreground person, and the first-level key corresponding to the first-level lock cylinder 3 is managed by an administrator. When needs unblock emergency exit, at first need the administrator to insert one-level key one-level lock core 3, through the rotation of one-level lock core 3, let locating part 6 rotate, so locating part 6 has just removed the restriction to driving medium 5, then proscenium personnel insert second grade key second grade lock core 4, through the rotation of second grade lock core 4, drive driving medium 5 and move back, in lock shell 1 just is got back to spring bolt 2 like this to realize the unblock.

The movement of the driving member 5 is limited by the limiting member 6 in many ways, for example, a groove may be formed on the driving member 5, and the limiting member may enter the groove; the utility model provides a concrete implementation mode: the end of the limiting element 6 has a catch 60, and the end of the transmission element 5 has a catch for the catch 60. When the locking head 60 of the locking element 6 enters the locking opening of the transmission element 5, the transmission element 5 cannot be moved back.

Last worth mentioning is, remove about in order to let second grade lock core 4 drive driving medium 5, the utility model discloses a concrete implementation mode is also provided: two upper and lower guide posts 10 are arranged on the lock shell 1, a transmission piece 5 is provided with a guide long hole 50, the guide posts 10 are positioned in the guide long hole 50, the second-stage lock cylinder 4 is connected with the second-stage toggle piece 40, the transmission piece 5 is provided with a toggle long hole 51, and the second-stage toggle piece 40 is positioned in the toggle long hole 51. When the secondary lock cylinder 4 rotates, the secondary stirring piece 40 can stir the transmission piece 5 to move left and right under the guidance of the guide column 10.
