The 3rd goes on foot, and counterclockwise is rotated further the lock core a of top monolock with hand, and lock core is stirred driving lever and rotated, and driving lever drives the again backward retraction (seeing the arrow among Figure 15 and Figure 16) of the first locking bolt 20.At this moment, because the protrusion Qu Houyi of top linkage block, the top of second row and the inboard control of the 3rd row tongue fixedly tongue 45 under the effect of its spring 47, protrude upward plane domain to this place ahead, linkage block inclined-plane (among Figure 16 three small circles of below namely represent first, second, and third inside front of arranging fixedly tongue 45 all stretch out as seen), in the underside tongue 44 indentation frameworks of second row and the inboard control of the 3rd row tongue, namely the coupler body of below linkage block is no longer stopped (invisible underside tongue among Figure 17) by active tongue simultaneously.The below of the 3rd exclusive side control tongue fixedly tongue owing to the extruding in the protrusion district of linkage block below being subject to makes progress in the indentation framework, thereby the top active tongue of the 3rd exclusive side control tongue protrudes upward under the effect of its spring 46, hooked by the coupler body of top linkage block (among Figure 16 the small circle of top namely represent the 3rd exclusive side control the top active tongue of tongue).
The 4th goes on foot, and counterclockwise is rotated further the lock core b of below monolock with hand, and lock core is stirred driving lever and rotated, and driving lever drives the second locking bolt 21 and again retracts backward.At this moment, after driving the below linkage block, moves the second locking bolt 21, then the below of the 3rd exclusive side control tongue fixedly tongue 45 extend out to the plane domain in this place ahead, linkage block inclined-plane downwards, the top active tongue 44 of this control tongue under the effect of its spring 46 downwards in the indentation framework, thereby this top active tongue 44 (the 3rd exclusive side active tongue) no longer stop above the coupler body of linkage block.So far, the second locking bolt 21 is retracted fully, and namely the below monolock is opened fully.
The 5th step because the 3rd exclusive side active tongue 44 has no longer stopped the coupler body of top linkage block, 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 mutual control lock is opened fully, finishes the process of unblanking.
As seen, when many groups mutual control lock of first embodiment of the invention is provided with two groups of monolocks and its united control device and is provided with three row's control tongues, need minute five steps could realize unblanking.
Note that simultaneously according to what above introduce and unblank step as can be known, because two groups of monolocks all are respectively equipped with resilient mounting, above the first step is rotated, behind the monolock, need to screw with hand the key of top monolock; Otherwise if unclamp this key this moment, under the recoil of spring effect of the resilient mounting of monolock, the first locking bolt can forwards stretch out up, thereby even rotate the lock core of below monolock, lock can not be opened again.In like manner, behind monolock above the rotation of the 3rd step, also need to screw with hand the key of top monolock; Otherwise if unclamp this key this moment, then up under the recoil of spring effect of the resilient mounting of monolock, the first locking bolt can forwards stretch out, thereby can not unblank.In other words, when unblanking, needs one people with the hands rotates respectively successively the lock core of upper and lower monolock and maintains.
Many groups mutual control lock to first embodiment of the invention further improves, and when it establishes two row's control tongues, then only needs minute four steps just lock can be opened; And when it is provided with four row's control tongues, then just need minute six steps lock could to be opened; In other words, when it is provided with N row control tongue, just need a minute N+2 step lock could be opened.
When many groups mutual control lock of second embodiment of the invention has three groups of monolocks, two united control devices and three resilient mountings, just need the collaborative lock core that rotates respectively successively the upper, middle and lower monolock with hand of two people, substep is unblanked, and does not repeat them here.
Closing many group mutual control locks of the present invention then very simple, referring to Fig. 2, only need clockwise rotate first the top monolock, clockwise rotate the below monolock again, is that available two locking bolts are lived door lock in two steps.Certainly, when having the people to be in, also can only clockwise rotate top monolock or below monolock, namely only with a locking bolt door lock be lived, with convenient ensuing unblanking.
According to top description as can be known, many group mutual control locks of the present invention have following advantage:
1. theftproof is better.As mentioned above, open many group mutual control locks of the present invention, need generally speaking a people with the hands to rotate respectively successively the lock core of upper and lower monolock, minute four steps or minute five steps unblank, and above rotating, the first step behind the monolock, also needs to screw the key of top monolock with anti-rebound 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, this moment, his uncontrollable first monolock was to prevent its resilience again.
2. safety is better.In a lot of very important occasions such as warehouse, safety cabinet, if set to need two people even the many people door lock of unblanking simultaneously just to allow to open, adopt the mutual control lock of organizing of the present invention just can realize only having the unblank function that just can open of many people's cooperations more.If one of them monolock is destroyed, namely use key other the monolock of also not opening, because have each other the joint control effect, the centre lacks the whole mutual control 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 also symmetrical, thereby easy to manufacture.
Although the preferred embodiments of the present invention are described in detail and illustrate, 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 protection scope of the present invention that it is limited by claims.
