The specific embodiment

Implement 1:

This is the embodiment of " many locks are equipped with ".Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the accompanying drawings of present embodiment, and core content mainly is illustrated among Fig. 3, is please understood in conjunction with each figure.

This multi-lock linkage device is made up of base plate 21, lockset 22, promotion slide plate 23, controlling organization connecting rod 24 and insertion restraint device 100.Core apparatus is to insert restraint device 100, it by socket 1, add plug thing 3, insertion rod 11 and pushing ram 12 and form.Sliding cavity 2 (referring to that respectively there is the middle cavity of 3 limiters 9 both sides) is arranged in the socket 1, place at least one in the sliding cavity 2 and add plug thing 3, adding the plug thing here is 3, adding plug thing 3 slides in sliding cavity 2, in normal direction one side of adding plug thing glide direction, having the head 17 insertion sockets of at least two insertion rods 11 to contact with adding the plug thing, here is that 4 insertion rods are arranged.Catch bar 12 promotes insertion rod 11 rear portions to be made the insertion rod insertion and leaves socket, and here insertion rod rear portion and catch bar combine as a whole.Insert for the ease of insertion rod and to enter smoothly when adding plug thing space, adding the plug thing has the inclined-plane 4,5 of importing respectively with the part that the insertion rod head is in contact with one another, and the angle on importing inclined-plane can be chosen between 15 °～75 ° as required.Socket sliding cavity 2 both sides limiters 9 are not enough to limit fully the normal slip of adding the plug thing; so restricted chute 6 that adds plug thing glide direction in socket sliding cavity 2; adding plug thing 3 also will have the protrusion 7 supporting with chute, and this not necessarily depends on the circumstances certainly.The length Q of socket sliding cavity equals to add the total length T that fills in thing and adds that insertion rod width R takes advantage of the insertion rod quantity n of permission insertion to add the certain clearance amount, and the quantity n of insertion rod gets 1 (implementing then to get 2 in 2) here.That is to say: the length Q of socket sliding cavity deducts the total length T that adds the plug thing, and remaining size F just in time allows the width R of an insertion rod insert sliding cavity, and promptly F=R also will leave certain interval certainly.The sliding cavity here two ends up and down is disconnected, is called closed sliding cavity, and the sliding cavity of implementing in 6 is that the circular two ends that do not have that link up are called open sliding cavity.Rule as can be seen in adopting this device of closed sliding cavity, what the length Q of closed sliding cavity equaled insertion rod puts overall width K (from the limit of first insertion rod to the last limit of a last insertion rod, see Fig. 3), add and multiply by integer quotient n again after quantity that the quantity of plug thing equals insertion rod deducts 1, here n gets 1 and belongs to most economical scheme, to add the plug thing be exactly 3 so insertion rod quantity is 4, if but adopt the steel ball, steel column etc. of finished product, then n not necessarily gets 1.If when the insertion rod of (see figure 6) is put perpendicular to sliding cavity is straight in the enforcement 2, also meet this rule as can be seen.Catch bar 12 can pass through its extension, and for example dead bolt 25 contacts side surfaces of dead bolt baffle plate 13 and lockset 22 are controlled by dead bolt.Insertion rod 11 can be promoted to insert the sliding cavity 2 of sockets 1 by catch bar 12, also can mobile socket 1, and make insertion rod 11 insert the sliding cavities 2 of sockets 1 relatively.

See Fig. 4,4 locksets in figure have any 3 unlatchings, have only 1 to close, and its dead bolt side of closing has stopped dead bolt baffle plate 13.Because socket 2 is to be riveted on to promote can move with promoting slide plate 23 on the slide plate 23, the dead bolt baffle plate 13 of catch bar 12 on fixing it also can move with promotion slide plate 23 but can relatively move on promotion slide plate 23, drive controlling organization connecting rod 24 promotion slide plates 23 by controlling organization and be moved to the left this moment, 3 dead bolt baffle plates that do not stopped follow catch bar and insertion rod to move to left smoothly, the dead bolt baffle plate 13 that is stopped, catch bar 12, insertion rod 11 is limited and can not moves to left, make insertion rod 11 relatively insert in the socket 1 sliding cavity with add the space of filling between the thing, promotion slide plate 23 moves to left and is unaffected, and bolt is opened smoothly by controlling organization.G among the figure is meant the dead bolt of closing.

If have only 2 locksets to open, have 2 dead bolt baffle plates and be obstructed, can not allow 2 insertion rods insert in the socket sliding cavity, so being moved to the left, controlling organization connecting rod 24 promotion slide plates 23 are obstructed, bolt can not be opened by controlling organization.Realized " many locks are equipped with one ", perhaps be called 4 and select 3 that if 3 locksets only are installed on the base plate, just become 3 to select 2, the rest may be inferred.

Implement 2:

This is the embodiment of " many locks are equipped with two ".Fig. 5, Fig. 6, Fig. 7, all be the accompanying drawing of present embodiment, summary of the invention mainly is illustrated among Fig. 6, is please understood in conjunction with each figure.

With implement 1 and different be: after 1, the length Q of sliding cavity deducts the total length T that adds the plug thing, residual space F can allow the width R of 2 insertion rods insert, i.e. F=2R.2, owing to be difficult to resemble and allow insertion rod insert implementing 1, when inserting, insertion rod can swing a low-angle perpendicular to the sliding cavity straight line, thus allow insertion rod 14 (see figure 6) rear portions be enclosed within on the pillar 16 of catch bar by circular hole 15, and can swing around pillar 16 axis.The insertion rod 14 here is different with insertion rod 11 shapes of implementing in 1, and its right side is that effective insertion portion is identical with enforcement 1, and its left side or rear portion are more slightly to gain in strength and circular hole 15 is arranged.Catch bar 12 also will increase a pillar 16.3, sliding cavity two sides of socket are added the normal limiter that slides of plug thing without any limiting, so must restrictedly add the chute 6 of plug thing glide direction, and the cover plate up and down of socket all has chute 6, add to fill in thing 3 protrusion 7 supporting with chute also will be arranged.4, also to increase a guiding surface 8 in the socket, be beneficial to the insertion of insertion rod.Comprise in the other parts that dash number is all identical with enforcement 1.Can understand with reference to implementing 1.

Fig. 7 is the action schematic diagram of " many locks are equipped with two ", and 6 locksets in figure have any 4 unlatchings, have only 2 to close, and its dead bolt side of closing has stopped dead bolt baffle plate 13.Because socket 2 is to be riveted on to promote can move with promoting slide plate 23 on the slide plate 23, the dead bolt baffle plate 13 of catch bar 12 on fixing it also can move with promotion slide plate 23 but can relatively move on promotion slide plate 23, drive controlling organization connecting rod 24 promotion slide plates 23 by controlling organization and be moved to the left this moment, 4 dead bolt baffle plates that do not stopped follow catch bar and insertion rod to move to left smoothly, 2 dead bolt baffle plates 13 that stopped, catch bar 12, insertion rod 11 is limited and can not moves to left, make insertion rod 11 relatively insert in the socket 1 sliding cavity with add the space separately of filling between the thing, promotion slide plate 23 moves to left and is unaffected, and bolt is opened smoothly by controlling organization.G among the figure is meant the dead bolt of closing.

If have only 3 locksets to open, have 3 dead bolt baffle plates and be obstructed, can only allow 2 and can not allow 3 insertion rods insert in the socket sliding cavity, be moved to the left and be obstructed so controlling organization connecting rod 24 promotes slide plates 23, bolt can not be opened by controlling organization.This has just realized " many locks are equipped with two ", perhaps is called 6 and selects 4, if 5 locksets only are installed on the base plate, vacate an installation lockset and has just become 5 to select 3, and the rest may be inferred.

Can also realize " many locks are equipped with three " " many locks are equipped with four " according to above-mentioned principle, but from the practical place of majority, " many locks are equipped with two " used enough.

Implement 3:

See Fig. 8, used two " alternative " device 200,201 among the figure, form a set composite.M1, M2 are standby locksets among the figure, and M3, M4, M5 are the locksets that normal open operation is used, and M3, M4, M5 have used plain disk formula mechanical code lock here, also can use this lockset equally in the aforementioned embodiment.Under normal circumstances have only M3, M4, M5 all to open, bolt could be opened.Under the improper situation,, just can open bolt as long as open among standby lock M1, the M2 any one.Different with

enforcement

1,2, M3, M4, M5 can not be as standby locksets, and M1, M2 have the highest weight limit.

Implement 4:

See Fig. 9,, only allow each door of opening sometimes in the place that has a plurality of.Here used and inserted the single unlatching that restraint device 300 can control gate, 3 doors 301,302,303 have been arranged among the figure, can only open a door at every turn, only closed the door of opening, could open the next one.

Implement 5:

See Figure 10, some many key devices only allow a button 305 to press, otherwise can break down, and adopt the insertion restraint device of pure machinery here, and making at every turn can only be by next button.The obstacle 9 of sliding cavity two sides of the socket 1 here is enough to limit the normal slip of adding plug thing 3, so do not need to implement 1, implement the chute 6 in 2.

Implement 6:

See Figure 11, this is a kind of insertion restraint device of annular, add plug thing 3 can employing figure in cylinder shown in the left side, steel ball, but preferably among the figure arc shown in the right side add plug thing 3.With implement 1, implement 2 different be sliding cavity be communicated with or claim open.And implement 1, implement sliding cavity two ends in 2 be disconnected be called closed.

Described above only is part embodiment of the present utility model, is not that design of the present utility model and scope are limited, so according to the equivalent variations that description scope of the present utility model is done, still belongs to the protection domain of the utility model patent.
