The 4th goes on foot, the lock core b of monolock below counterclockwise being rotated further with hand, and lock core is stirred driving lever and is rotated, and driving lever drives the withdrawal backward once more of second locking bolt 21.At this moment, second locking bolt 21 moves after driving below interlock piece, then the below of the 3rd exclusive side control tongue fixedly tongue 45 extend out to the plane domain in this place ahead, interlock piece inclined-plane downwards, the movable tongue 44 in top of this control tongue under the effect of its spring 46 downwards in the indentation framework, the coupler body of piece thereby the movable tongue 44 in this top (the 3rd exclusive side activity tongue) links above no longer stopping.So far, second locking bolt 21 is withdrawal fully, and promptly the below monolock is opened fully.

The 5th step because the 3rd exclusive side activity tongue 44 has no longer stopped the coupler body of top interlock piece, only needed counterclockwise to rotate the lock core a of top monolock, can open the top monolock.So far, many groups of first embodiment of the invention cross complaint lock is opened fully, finishes the process of unblanking.

As seen, when many groups cross complaint of first embodiment of the invention lock is provided with two groups of monolocks and its united control device and is provided with three row's control tongues, needed to divide five steps could realize unblanking.

Note that simultaneously according to what above introduce and unblank step as can be known,, above the first step is rotated, behind the monolock, need screw the key of top monolock with hand because two groups of monolocks all are respectively equipped with resilient mounting; Otherwise this moment, under the recoil of spring effect of the resilient mounting of monolock, first locking bolt can forwards stretch out up if unclamp this key, thereby even rotate the lock core of below monolock again, lock can not be opened.In like manner, behind monolock above the rotation of the 3rd step, also need to screw the key of top monolock with hand; Otherwise this moment is if unclamp this key, and then up under the recoil of spring effect of the resilient mounting of monolock, first locking bolt can forwards stretch out, thereby can not unblank.In other words, when unblanking, needs one people with the hands rotates the lock core of upper and lower monolock successively respectively and maintains.

Many groups cross complaint lock to first embodiment of the invention further improves, and when it establishes two row's control tongues, then only needs to divide for four steps just lock can be opened; And when it is provided with four row's control tongues, then just need to divide for six steps lock could be opened; In other words, when it is provided with N row control tongue, just need to divide the N+2 step lock could be opened.

When many groups cross complaint lockset of second embodiment of the invention has three groups of monolocks, two united control devices and three resilient mountings, just need two people to work in coordination with the lock core that rotates the upper, middle and lower monolock with hand successively respectively, substep is unblanked, and does not repeat them here.

It is then very simple to close many group cross complaint locks of the present invention, referring to Fig. 2, only need clockwise rotate the top monolock earlier, clockwise rotates the below monolock again, is that available two locking bolts are lived door lock in two steps.Certainly, when the people is in, also can only clockwise rotate top monolock or below monolock, promptly only door lock be lived, with convenient ensuing unblanking with a locking bolt.

According to top description as can be known, many group cross complaint locksets of the present invention have following advantage:

1. theftproof is better.As mentioned above, open many group cross complaint locks of the present invention, need a people with the hands to rotate the lock core of upper and lower monolock successively respectively generally speaking, divided for four steps or divided for five steps unblanked, and above rotating, the first step behind the monolock, also needs to screw the key of top monolock in case resilience with hand.Like this, can prevent effectively that the robber from illegally unblanking with instrument, because the robber is after with tamper tool first monolock, if will drive second monolock again, this moment, his uncontrollable first monolock was to prevent its resilience.

2. safety is better.Such as a lot of very important occasions such as warehouse, safety cabinets, need two people even the many people door lock of unblanking simultaneously just to allow to open if set, adopts many group cross complaints of the present invention to lock just can to realize and have only the unblank function that just can open of many people's cooperations.If one of them monolock is destroyed, promptly use key other the monolock of also not opening, because have the joint control effect each other, the centre lacks the whole cross complaint lock of all not opening of any step, thus door can't be opened.

3. structure is very symmetrical, can not cause high manufacturing cost.Such as, each organizes the symmetrical configuration of monolock, and the structure of united control device is symmetry also, thereby easy to manufacture.

Though the preferred embodiments of the present invention are described in detail and illustrate that the present invention is not limited thereto.Should be known in that those skilled in the art can carry out numerous modifications and variations under the condition that does not deviate from spirit of the present invention and principle, and do not break away from it by protection scope of the present invention that claims limited.
