Description

Be used in particular for the safety lock of the type with deadlock plates of armoured door

Technical field

The present invention relates to a kind of safety lock with high use flexibility ratio that is generally used for door, gate, strongbox etc.

Background technology

Known in building site, the door in the room in construction is provided with at least one for the lock of the type of armoured door, makes to exist many locks on whole building site, according to these locks of work that carry out in house or complete, is unlocked or closes.

First therein remain the building site that need of work carries out (can be for example the work of pipeline or electric type or for completing the work of their internal work), needing can not be to use master key (being handed over to room owner's last key) to open room, and for example, but () used so-called " building site key ", (being retained in the key in the workman's hand that freely enters room) opens room.

Sometimes, except master key and building site key, so-called " service key " is also provided, and house owner can be handed over to described service key (for example) it can rely on and allow freely to enter room (for example) to carry out necessary every day of clean people subsequently.

Therefore, building site key can not just in time have the purposes of the permission of service key and/or master key.

Therefore, according to foregoing, each lock by the door that exists on building site is provided with building site key, service key and master key, if the groundwork in room completes according to this sample loading mode, thereby make only to prevent that the people that may rely on from entering room, so described master key can get rid of with service key the possibility of using building site key equally.

Although should be noted that building site key can open on building site, exist all locks of roomed all door, serve key and master key and be merely able to exclusively open the lock that they mate.

For above-mentioned reasons, so at least there is the lock of three kinds of main Types on market, described lock uses building site key and master key and may serve key.

For example, the lock that prior art is known a type, it has the mechanism of the part operation opening and closing that are included in the interim pulley with the part being made of plastics, and has the cost comprising especially.

If completed all building site activities, so interim pulley is included design and is used for using new mapping relations to recover the last pulley replacement of a set of lever of lock.

Owing to need to affecting by removing thread escutcheon the fact (its task for being undertaken by professional) of door, so the shortcoming that this scheme exists is very general.

Consider and need to be for a long time need to replace interim pulley and consider lock (a kind of door of opening on the left side of two types of needs with last pulley, a kind of door for opening on the right, thereby conventionally only in the inside of door, carry out aforesaid operations) the fact, the composition of described lock significantly increases.

Finally, be pointed out that the lock of described type must installed site rather than test in factory, this mounting means can produce all shortcomings.

Lock and the above-mentioned lock of another kind of type are substantially similar, but whether design with last pulley, replace interim pulley, and it only designs the element that replacement can change the mapping relations of lock.

Therefore, with above-mentioned phase-locked ratio, substantially under the condition of lower cost, only replace mapping part, even if still existent defect was still so under (for example, because test is not carried out in workshop but directly in the tolerance difference of the general fact of carrying out in site being installed causing, thereby causing meaning the shortcoming of lock being taken off to install for action need).

The another kind lock using be at present can recompile type lock, it has building site key and master key.

In this case, dismounting lock, does not remain unchanged in the moment that is locked in installation of therefore installing.

In such lock, by special step and the special instrument of use, master key can be adapted mapping relations in such a manner again, makes to get rid of and uses building site key, therefore only can use master key.

The shortcoming of such lock is the general higher cost of code device, to such an extent as to the lever of its composition or plate move in the vertical direction except having to, also must also move in the horizontal direction to improve new coding by special instrument.

Therefore, the mechanism of described lock is very complicated and often easily stop up.

The specific embodiment

With reference to upper figure, by being appointed as on the whole reference marker 1, safety lock is shown.

Lock 1 (preferably but be not to be necessary for four-throw type) comprises that the box-like housing 3 of rigidity, its inside exist each other and connects floor spring door bolt 4 and snap member 5 in kinematics.

For the plate 14 that covers box-like housing 3, have keyhole 13, described keyhole 13 is for by an introducing of a plurality of keys that can operable lock 1.

In the keyhole 13 of safety lock 1, can introduce: the first key 2a, it can also operate other locks; At least one second key 2b, it is operable locks 1 only; And also preferred at least one the 3rd key 2c, it is operable locks 1 only.

Snap member 5 is supported plate 6 carrying, the retrieving position for opened lock of its snap member 5 in box-like housing 3, corresponding to the partly pull-out location of the pass locking of two cranks and fully moving horizontally between pull-out location corresponding to the pass locking of four cranks.

Spring bolt 4 moves horizontally for the retrieving position of opened lock with for closing between the pull-out location of locking successively in box-like housing 3.

At least there is the legacy system for mobile spring door bolt 4 in lock 1, this system comprises: the lever 11 of pushing box-like housing 3 for pivot being placed on to spring bolt 4 on 12 to; And for the momentum transfer of key being given to the mechanism of specified lever 11.

Stacked a pile deadlock plates or gorge 7 on base plate 6, each deadlock plates or gorge 7 move and have window 8 in the mode of vertical translation, and described window 8 has restriction corresponding to the tusk of the passage recess 9 of the coding of the key of lock 1.

In order to support snap member 5, the deadlock element 10 or the wheel rim that are arranged on window 8 inside are fixed on plate 6.

Especially, each deadlock plates 7 has five recesses, and described recess is divided into for driving second and the recess X of four-throw and spring bolt 4 and for driving first and three-throw recess Y of snap member 5.

According to significant aspect of the present invention, lock 1 comprises: for the device that the first key 2a was lost efficacy, its can be at least by the second key 2b with can also be operated by the 3rd key 2c especially; And drive for closing locking 1, the particularly device of at least one member of spring bolt 4 regardless of deadlock plates 7.

Therefore, key 2b and 2c work to deadlock plates 7, thereby make the tusk of window 8 produce one, show open channel, thus deadlock element 10 slip that is activated in described passage.

On the contrary, key 2a works to deadlock plates but does not make the tusk of window produce coupling, therefore open channel not.

No matter the device of deadlock plates 7 and driving spring door bolt 4 comprises at least one cam 15, described cam 15 is activated by the first key 2a and the protuberances of the plate 17 of spring bolt 4, particularly support spring door bolt 4 itself is worked.

Therefore, according to particularly advantageous aspect, spring bolt 4 not only can drive by lever 11 (device of the second key 2b and the 3rd key 2c) in known manner, and can be independent of by the driving of lever 11 and additionally by cam 15, drive.

Cam 15 and lock 1 twisting, and there is at least one tusk 18, described tusk 18 can mesh with at least one anti-tusk 19 of the first key 2a.

The first key 2a can make cam 15 rotate between the pull-out location of spring bolt 4 and retrieving position.

Especially, cam 15 is by the device of hinge pin 20 and overlay 14 twistings of box type body 3, the axle of described hinge pin 20 with snap member 5 and the common horizontal translation direction of spring bolt 4 quadrature, again with the vertical direction quadrature of the displacement of deadlock plates 7.

Cam 15 can be contrary with twist mode back-moving spring 26 and the effect by twist mode back-moving spring 26, by the first key 2a, be driven, is wound on hinge pin 20, in a side, towards cam 15, at opposite side, towards box shell body 4, driven, and this is easy to make its pull-out location towards spring bolt 4 automatically to return.

Ineffective part instead comprises saddle 21, described saddle 21 is at least by the second key 2b with preferably also activated by least the three key 2c, and described saddle 21 has and the element 22 of engagement, described element 22 is designed to make it can be arranged on key 2a the direction rotation that the direction of motion on cam 15 is contrary.

Saddle 21 obtains from the same plate 6 of supporting snap member 5.Engaged element 22 was initial position (Fig. 2) (the first key 2a remains valid under this position), centre position (Fig. 4) (the first key 2a lost efficacy under this position) and final position (Fig. 5) (the first key 2a finally lost efficacy under this position) temporarily.

In initial position, engaged element 22 departs from cam 15 in such a manner, makes the result as anti-tusk 19 rotation of driving cam 15 with the engagement of the tusk 18 of cam 15 due to the first key 2a, can freely regain spring bolt 4.

At centre position place, engaged element 22 is towards cam 15, thereby makes its result as the engagement of the anti-tusk 19 of the first key 2a and the tusk 18 of cam 15 and rotate to the contrary mode of retrieving position from the pull-out location of spring bolt 4.

At place, final position, engaged element 22 driving cam 15 rotations, until it is set in the position of inactivation forever, in this position, it no longer works with the first key 2a.

Mesh for covering box type body 3 at bearing 30 places that move on the contrary with spring 25 and the column bolt 24 of spring 25 generation effects is supported and be designed for lock 1, particularly plate 14 by cam 15, thereby cam 15 is suppressed to its invalid position place.

Advantageously, the first key 2a is building site key, and the second key 2b is master key, and the 3rd key 2c is backup service key.

In this manner, master key is designed for and in the rotation of predetermined quantity or after starting, finally and automatically gets rid of building site key and interim and automatically get rid of service key.

Service key is designed for successively in the rotation of predetermined quantity or after starting gets rid of building site key temporarily and automatically, and the quantity of described rotation or startup finally and is automatically got rid of the quantity of rotating or starting under the condition of building site key lower than master key.

Substantially, lock 1 can improve key was lost efficacy, and wherein said key operated described lock 1 makes each key automatically lose efficacy because another has the key of different coding finally or temporarily.

At lock 1, be in the described situation of four-throw type, use has the building site key of one or two crank, service key can automatically lose efficacy temporarily, and building site key is while being used lower two cranks, and master key can automatically lose efficacy temporarily and serve finally automatically inefficacy of key.

Each key 2a, 2b, 2c are preferably but must not be double head type key.

Except anti-tusk 19, the first key 2a also has two neutral heads (neutral bit) that can not make it drive deadlock plates 7.

Key 2b and 2c instead have corresponding to first of recess X with corresponding to second of recess Y, and every stature all has and the as many recess of deadlock plates 7.The zone line of key 2b and 2c does not have coding and its object to be to drive in the mode of horizontal translation the plate 6 of supporting snap member 5.

Two statures of key 2a, 2b and 2c repeat, and with respect to 180 ° of the central rotations of key, reason is that deadlock plates 7 and cam 15 arrange asymmetrically in box shell body 3.

Below the concise and to the point operation of describing lock 1.

In the structure of Fig. 2, locking 1 is initially: even if snap member 5 is regained, spring bolt 4 is pulled out and made to lock 1 and be closed.

By key 2a being inserted to keyhole 13 and rotating, anti-tusk 19 works for the tusk 18 of cam 15, therefore drives in rotary manner (rotation in the counterclockwise direction as shown in FIG.).In rotation, cam 15 is the protuberance 16 of slurcam 17 successively, thereby spring bolt 4 is regained until lock 1 is unlocked (Fig. 3).In this motion process of cam 15, column bolt 24 is in the interior slip of arcuate slots 27 of plate 14, and the flexural center of described arcuate slots 27 is on rotary pin shaft 20.

From the structure of the lock 1 of Fig. 2, if key 2c inserts keyhole 13, after two locking cranks, saddle 21 moves to such position, in this position, engaged element 22 meshes (Fig. 4) with the shaft shoulder 23 of cam 15, therefore suppresses cam 15 and rotates up in the side that can make spring bolt 4 regain.Therefore, if in the structure of the lock 1 after this, key 2a inserts in keyhole 13 again, under any circumstance key 2a can not regain spring bolt 4, to causing cam 15 to be blocked.Only there are two key 2c that open crank and can reactivate key 2a.

From the structure of the lock 1 of Fig. 2, if key 2b inserts keyhole 13, when carrying out the second two locking cranks, 21 of the saddles enough degree for engaged element 22 of advancing, by the shaft shoulder 23 engagements with cam 15, cam 15 is shifted onto to the position (Fig. 5) of inactivation: in the rotation of cam 15, thereby column bolt 24 is regained the reaction force that has overcome spring 25, make from groove 27 out, then by button effect, continue to penetrate bearing 30, thereby cam 15 is remained on to the position of inactivation.In this position, cam 15 can not interact with key 2a, thereby finally loses efficacy.In addition key 2c lost efficacy temporarily, thereby caused the coding of the coding of two cranks and four cranks of key 2b different.Therefore, key 2c only just activates again when the one or two unlatching crank of initiation key 2b.Start below four while opening crank, key 2a keeps inefficacy, and reason is as mentioned above, and cam 15 remains on the position of inactivation.

According to lock of the present invention, use not expensive basic system, on the one hand building site key is all identical with all locks on building site, on the other hand not with the instrument of any type, do not need professional's intervention and do not need on-site opposite house to the condition of testing under can with automatic mode by especially simply and functional system and mechanism get rid of automechanism device.

According to lock of the present invention can neutral zone for opening on the left side with opening door on the right.

Not the most unessential, according to lock of the present invention, can provide a large amount of locks, to such an extent as to building site key plays a role according to mode complete and that jam plate is irrelevant.

In fact, the material of use and size can be any according to the state of the requirement of prior art and definite.
