Description

A kind of locking device

The application system divides an application, and the applying date of original application is 96.12.31, and application number is called " high-safety blade door lock and manufacture method thereof and application " for the 96119717.X name.

One, technical field: the invention belongs to lock, performance height especially, the blade lock that cost is low, purposes is wide.

Two, background technology: known blade lock has multiple, and GB GB8387-87 is a kind of blade lock that does not have tapered end.Blade lock of the present invention mainly is made up of lock core, tapered end, blade, spring and key.Also have lock body, dead bolt, dial etc. in the door lock.This blade lock uses widely in all kinds of locks, is many with door lock and automotive lock especially.Blade lock pin is generally formed by allumen die casting, is the die casting lock core.Most automotive lock is this lock core.Also having the stamping forming lock core of a kind of metal sheet, is the punching press lock core.The punching press lock core is owing to structure, technology are simple, and is lower than die casting lock core cost.The blade lock of prior art, ubiquity poor performance, the shortcoming that cost is high.Poor performance mainly cannot not refer to anti-ly draw, not anti-drilling, anti-unloading, not preventing universal key.The anti-or not foreign matter of finger of drawing is drawn and is dialled.A kind of tool of exchanging work of drawing that the master key principle unblanks that uses is arranged, on a forked stalloy or steel wire, have can bi-directional movable the elasticity hook.This instrument can be opened various blade locks effectively.General in fact blade lock only needs with two steel wires, one lock core to a layback, give a revolving force, lock core is turned an angle, another root is drawn in the spoon groove, make the blade retaining on the edge of tapered end lock hole, use the principle of master key, can unblank.The anti-outer end structure that refers to tapered end that unloads is not prevented unloading.

Existing blade lock also has following not enough:

1, the punching press lock core has frame, and this frame has limited vane travels, is unfavorable for improving tooth number and strengthens confidentiality, safety.Existing punching press lock core is joined the single head blade, and not only the tartar amount is few, and the anti-poor performance of drawing.Only adorn a blade on the lock core in a hole or the lattice, a blade is joined a spring, and this lock core can not be loaded onto more blade in limited space, in other words, can't dwindle the lock core volume.Can't improve confidentiality, the scope of application is poor, and cost is higher relatively.

Existing blade, have single head and two first two.Single head refers to only lock hole that can advance on the tapered end of blade.Double end refers to that blade two can both advance lock hole.The single head blade is used for the punching press lock core, and the double end blade is used for the die casting lock core.The single head blade is subjected to the restriction of lock core structure, its anti-poor performance of drawing.The double end blade prevents that drawing performance is relatively good.Two kinds of tapered ends all can not be accomplished really burglary insurance effectively, and cost is higher.

2, existing blade measures is few, and weak effect is simple in structure, is unfavorable for improving secrecy.

3, existing blade lock is generally not anti-drilling, though the lock that has has anti-drilling layer, anti-drilling layer is not anti-to be unloaded.Anti-drilling layer as prior art can not firmly be connected with the tapered end outer casing sleeve, tears the cap rock of tapered end outside, and anti-drilling layer just can have been laid down.Lay down anti-drilling layer, tapered end is with regard to non insurance.Have with the riveting of anti-drilling layer on tapered end, though prevent like this unloading, frame mode is not attractive in appearance, the cost height.

4, the key positioner method of prior art and tooth punching method cost height.Location and the anti-ditch muscle of the effect of pulling out of drawing are being arranged on the key.In fact anti-to draw effect very little for the ditch muscle that matches with key of lock core, because of key need have certain intensity, just certain thickness must be arranged, as long as thickness is arranged, a spoon groove just has width, has the just difficult anti-foreign matter of width to enter to draw group.Because of the comparable key of foreign matter is thinner, the easier variation of shape.And these ditch muscle have restricted the global design of lock and have increased processing cost.The tooth punching method of prior art is to go out anodontia key billet, processes by tooth by required tooth number again, and time-consuming like this, cost is higher.In the prior art, the necessary strictness of key of having opened tooth is along with tapered end is walked, and the interchangeability of key is poor, is not easy to management.The key of prior art, also cumbersome when in lock core, assembling blade, must conscientiously check the number, work efficiency is low.

5, the square tongue of prior art (comprising multidirectional dead bolt) stretches out and withdrawal, needs to finish with key rotation lock core or with handle, is inconvenient to like this use.In case forget or the old man, child does not use is non insurance.A kind of door lock (uvula is that a kind of head is two-sided pointed, the part of having an effect with dead bolt in lock body) of oblique lingual ribbon uvula is arranged, and uvula is subjected to the active force of doorframe at closing time, and uvula discharges oblique tongue a bit, the part side's of replacement tongue effect.But it is shorter to discharge length, and generally in 8 millimeters, insufficient strength is good.Moreover tiltedly flapper is locked the effort of closing the door, because of tiltedly tongue and dead bolt box rubbing surface are big, and due to the stroke length.When the door lock of prior art is used for inward and outward opening door exchange, need oblique tongue is fallen to turn over direction, inconvenience is used.CN2100440U discloses a kind of cylinder lock locking mechanism, and its structure is can enter lock-out state automatically after swivel hook dead bolt and the collision of dead bolt box, and purpose is reliable, laborsaving, and cost is low.Weak point is that applicable surface is narrow, can not be used for the translation dead bolt, and structure is complicated.

6, in the prior art, rotation strip acts on driving chuck and stirs dead bolt, needs to be commonly called as " navel " and to realize by a transmission shaft tube, and this part is made trouble, cost height.Driving chuck needs to realize being connected by transmission shaft tube and lock cover.

Chinese patent 93207856-7 discloses a kind of unidirectional biserial blade lock core, its structure is that two two relative in same plane unidirectional blades are housed in the lock core blade groove, its key lumps together by two, forms double-row blades thus, and purpose is to solve automotive lock confidentiality difference and the anti-problem of dialling.Weak point is a poor performance, the cost height.Such as: will lock all blades earlier and press to its wide groove one side, revolving force of lock core is given in the back, blade is rebounded to narrow groove one side again, and at this moment, blade has been stuck on the edge of narrow groove, and lock has just been drawn out.Moreover this lock construction more complicated is difficult to carry out, so cost is also higher.

The objective of the invention is to: avoid above-mentioned deficiency, propose various new structures and method, improve the performance of lock, reduce cost of manufacture.About the performance of lock, GB GB8384-87 has stipulated: the content of four aspects such as secrecy, firmness, flexibility ratio, outward appearance.Therefore, purpose of the present invention specifically is:

1, the comprehensive low and good advantage of double end blade safety of punching press lock core cost, propose a kind of performance and cost perfect unity new lock core and with the combination of blade.Increase the quantity of blade in the certain volume internal cylinder, or say, when increasing lock core tartar quantity, dwindle the volume of lock core, improve the lock core scope of application, reduce cost.

2, overcome the blade lock and do not prevent drawing, not the disadvantage of preventing universal key.

3, solve the problem of the not anti-drilling or weak effect of tapered end.

4, provide a kind of simple and easy to do, tooth punching reliably and assembly method.Solve the orientation problem of no ditch muscle key.

5, make various door locks can both enter locking states automatically, the convenient use.

6, solve to rotate central siphon difficult processing, problem that cost is high.

Three, the object of the present invention is achieved like this for summary of the invention:

Door lock of the present invention mainly is made up of lock core, blade, spring, tapered end, cover cap, anti-drilling layer, key, dead bolt, dial etc., and existing division is as follows.

One, lock core assembly and assembly method.The lock core assembly refers to the various combining structures be made up of lock core, blade, spring etc.

A, change lock core structure.Remove the frame of punching press lock core, the vane hole of lock core or lattice are the tabular of the opening shape or the atresia lattice of no circumferential perimeter.To increase the stroke of blade, improve tooth number, increase confidentiality and safety, also can strengthen the intensity of lock core self by changing lock core structure.

B, punching press lock core assembling double end blade.Here " the punching press lock core " of indication is all lock cores that formed through punch process by metal material." double end blade " is meant that blade two can both enter all blades of lock hole.The present invention combines punching press lock core and double end blade.The punching press lock core can be made by a metal sheet, as steel plate, iron plate, copper coin, aluminium sheet etc., interior dress double end blade.Lock core can be axially or doubling warp architecture radially, also can the side of being, the pipe shape, and as " u " type structure or other similar structures, can there be the raised item muscle and/or the breach of branch root piece the inside, and lock core can be the strip of sheet with opening breach.The annex that reinforcing rib can be arranged or gain in strength.Blade is two motion up and down in " u " type groove.Two all can side by side not enter tapered end and play locking action.The hook of hanging spring can be arranged on the blade---" hanging the spring ear ".Leaf spring can be positioned at " u " type groove outside.Lead two blades totally one helical compression spring or adjacent blades totally one elastic supporter mutually.The punching press tapered end is cylindrical, on the lock hole that enters for blade is arranged.The tapered end of punching press lock core can use or serve as a contrast supporting use in the casting tapered end separately.

C, punching press lock core of the present invention also can use in conjunction with the single head blade, during with the single head blade, unlike the prior art be that lock core can not have frame, be opening breach or strip of sheet.After this lock core removes frame, increased the stroke of blade, helped increasing differential, improved size of key, processed also easier.Change the mounting means of blade and spring in the prior art besides, hang on the support in the middle of the lock core, change adjacent blades into and support mutually, increase vane travels by spring.Single, double head lobe sheet also can be used in combination in same lock core.

D, a hole multi-disc.Be on the lock core one or each vane hole or the lattice two or more blades to be arranged.Two adjacent blades or a plurality of blade be totally one elastic supporter, and blade can be in the same way or counter motion, and blade is arranged in lock core vertically.As the blade of two relative motions of axially-aligned in a groove or lattice, their shared springs come off for preventing spring, on the blade hook formation can be arranged, and locate in order to spring.Between the blade partition can be arranged.Preceding method of the present invention can be in conjunction with application.

Two, blade of the present invention has multiplely, can be following structure:

1, bayonet socket blade, promptly one in blade or two have one or more breach.This breach may be stuck on the tapered end, makes blade can't adjust to the enable possition, thereby prevents the foreign matter unlatching.A breach all can be with in two and both sides as blade, and this breach is wider than the specific thicknesses of tapered end.As tapered end thick 0.8 millimeter, thick 0.5 millimeter of the lock hole edge on the tapered end, (this thickness can obtain by the method for punching press or cutting, and this featheredge helps the bayonet socket blade and enters), the blade breach is wide 1 millimeter.When drawing when dialling person's rotational lock core, breach is stuck on the tapered end, thereby can't be rotated further lock core, can't unblank.The structure that snaps in for bayonet socket is arranged on the tapered end.As the ditch muscle that snaps in for bayonet socket etc. being arranged on the die casting tapered end or stamping parts lining or similar bushing pipe being arranged.The bayonet socket blade also can be " T ", " I " type, and promptly the projection or the similar structures of being wider than blade left at one in blade or two, and this projection plays the effect of bayonet socket blade.

2, tip blade.One section of being one in blade or two is narrower than middle, and the both sides at two are the hypotenuse shape, to wide transition, are the hypotenuse shape by narrow.When illegal rotational lock core certain angle, when making blade be stuck on the edge of tapered end, the blade that does not block is under the effect of drawing the power of dialling, enter the tapered end lock hole, and the lock core that the extruding force of utilizing its hypotenuse will have been rotated a bit squeezes back latched position, makes jammed other blade be released return, reenters tapered end, lock core can't be rotated, thus make draw dial to wait foreign matter to open can't be successful.Because the tip blade can be stuck on the tapered end lock hole tightly, lock core can't be turned to draw and pull out required angle, because the tip blade automatically resets easily, pull out very difficulty again so draw.As 4 millimeters of one of blade or two head breadths, interlude is wide 6 millimeters, and to wide line, blade head both sides are the hypotenuse shape by narrow.Corresponding therewith, the lock hole on the tapered end also can be the hypotenuse groove shape with the first sample of blade.

3, backward vane.One that is blade greater than the lock hole on the lock body.Backward vane does not enter tapered end under lock-out state, do not play locking action this moment.Draw when dialling when foreign matter, drawn and allocate for firmly, backward vane enters tapered end, plays locking action, stops the behavior of dialling of drawing.Backward vane of the present invention is limited to the double end blade lock core.

4, gathering sill blade has a gap slot on the blade, this groove is stuck on the lock core, plays the guide-localization effect of blade movement.

The use that can respectively or combine of the blade of said structure or lock core, tapered end, or on the present a slice blade of combination.Use in conjunction with the bayonet socket blade as backward vane, it is better that it prevents drawing effect.Keyhole on the blade of the present invention can be open-type or enclosed type.Be that keyhole has side's opening or astomous poroid.

Three, Anti-drilling lock.Anti-drilling layer is housed in the outer end of tapered end.Anti-drilling layer can be positioned at below the tapered end cover cap, can be cup-shaped, sheet, flange shape or analogous shape, porose.With the sleeve lining interference fit, fixedly connected in sleeve, also riveted joint, welding etc. are fixedly connected.Even tear the cover cap of tapered end this moment, also can't take off anti-drilling headkerchief, can't destroy tapered end.Also can directly do anti-drilling layer, outside sleeve, fixedly connected with sleeve by cover cap.Such as making the cup-shaped cover cap with the material of 1.5 thick processing, with revolving the riveting method it firmly is connected with sleeve, cry " revolving the riveting method "." breach rendezvous method ", promptly sleeve and anti-drilling headkerchief respectively stay corresponding breach, rotate in place after inserting mutually, and both entangle fastening, fill breach both can not be rotated again, realize firmly connecting." embedding inlay technique ", promptly sleeve and have the cover cap of anti-drilling function respectively to make corresponding sides embeds his thing and makes it fixing between two corresponding sides.Also the method for available welding realizes that anti-drilling layer firmly is connected with sleeve outside sleeve.Prior art can't firmly be connected anti-drilling layer with sleeve.Anti-drilling layer self non insurance, whole lock had also just lost efficacy.

Four, a. plain film key and localization method thereof, key of the present invention is the plain film shape, no ditch muscle or pellet shot from a slingshot concave point.Ditch muscle on the key influences the intensity of key.Because it is that maintenance intensity must be thicker that the key of ditch muscle is arranged.Remove the ditch muscle and help doing key very thin, key has approached key and also can approach, and helps like this improving the confidentiality of lock and cutting down finished cost.

The key positioner method.All there are location-plate or similar structure in the about two ends of lock core.2 fixed lines, key is located.There is a location-plate entrance as the lock core outer end, can be held concurrently by keyhole before anti-drilling board or the lock core, the root of key can be blocked.There is a location-plate lock core inner end, can be held concurrently by correlated parts, and the key tip is blocked, and key has just been located in lock core like this.Also can there be location-plate the centre of lock core, and also available " blade positioning mode " promptly has the blade that plays the role of positioning in the lock core, key is blocked the location in opposite directions.

B, key tooth punching method.Go out unified basic profile of tooth during the key base together, and then open an above tooth, as open 1-2 tooth, be special tooth profile key with personal characteristics.According to the rule of tartar permutation and combination, its adjacent encoder differs a tooth.Adjacent code as 12345 can be 12344.Be reflected in a tooth that differs on the key.During tooth punching, the most shallow tooth can fix on more than 1 millimeter, with the difference of assurance with basic tooth." basic profile of tooth " is the unified tartar spread geometry on the key billet of being reflected in of a kind of tooth punching of setting according to the functional requirement of each side.Basic profile of tooth can have multiple difformity.Leave basic tooth and can lose the total quantity that tartar is arranged, but key tooth flower amount of the present invention can reach more than ten million kind, losing some does not influence its security performance.This key also is very easy to assembling, such as the blade of completely adorning basic profile of tooth earlier, fetches a cover then arbitrarily and has opened the key one of specific tooth and insert, and can find not to be inconsistent the blade of profile of tooth, then this blade is changed the assembling merit of promptly accomplishing.Key can not leave lock and need not resemble the prior art in process of production, otherwise just falls apart, and is hard to tell the lock of key correspondence.

Five, the method for work of dead bolt.The square tongue that is door lock does not need to transmit with key entering locking states automatically by various triggering controlling organizations at closing time.The square tongue here can be the circle tongue or change tongue or multidirectional dead bolt.From the motion mode of square tongue, divide translation and rotate two kinds, the translation side of being tongue rectilinear motion enters locking states, changes the tongue rotation of the tongue side of being and enters locking states.

1, square tongue escapement." catch ", refer to square tongue is kept a grip on, control and do not allow it enter the dead bolt box, be in opening; " indulge ", refer to decontrol, allow it enter the dead bolt box and be in locking states.Side's tongue is sharp, can resemble oblique tongue sample, and the single face point also can two-sided point.Side's tongue only part is with the inclined-plane.It is pointed only to be the inclined-plane on socket cap as the bicylindrical dead bolt.During opening, tip is exposed at 8 millimeter outside the lock body, and this is because door is gapped with doorframe, and tongue is finished to take off to catch to move above adding needs stroke, is advisable in 8 millimeter so expose generally.

The escapement that dead bolt is arranged in the lock box, its escapement can be forks, or the elasticity bolt, and fork can be with a spring, and recipient's tonguing goes out the acting in conjunction power of lock box action and spring, and fork is in diverse location respectively, open or closed condition but the controlling party tongue is in.The structure that acceptance and driving pendulum rod action are arranged on side's tongue.The back escapement structure of the opening the door side's of blocking tongue automatically only stretches out 8 millimeter.At closing time, the side's of release tongue all enters the dead bolt box automatically.It enters the degree of depth can as 10 millimeters, add 8 millimeters on inclined-plane more than 6 millimeters, and square tongue length can be in 18 millimeter.

2, uvula escapement.On the limit of square tongue, a uvula is arranged, uvula is made by metal sheet roof covering, and the uvula head is two-sided point or single face point or circular-arc, and uvula self or by the auxiliary side of acting on tongue is controlled at square tongue and opens or locked position.On side's tongue the structure of accepting little tonguing is arranged.During opening, uvula is exposed at lock body outside 8 millimeter.When opening the door, uvula can block dead bolt automatically and not expose.At closing time, uvula is subjected to the doorframe active force, the side's of acting on tongue, and the side's of release tongue all enters the dead bolt box automatically.Its stroke is more than 6 millimeters.Uvula has numerous species, and straight chip, circular pipe type, clubfoot formula are arranged; Single type, multi-piece type.Straight chip is that uvula is straight sheet; Circular pipe type refers to that uvula is the pipe shape; The clubfoot formula refers to that the uvula pin is crooked; Single type refer to uvula only one can finish the work; Multi-piece type refers to that uvula need be equipped with auxiliary and finish escapement work.

3, oblique tongue escapement.The oblique tongue of prior art has the uvula effect concurrently, plays the escapement effect of the other side's tongue.During opening, tiltedly tongue exposes outer 8 millimeter of lock body.In the lock body, tiltedly on the tongue escapement is arranged, its escapement can be to be equipped with a shifting block on the oblique tongue rod, and shifting block can be a sheet metal, on the structure that drives the fork motion is arranged, act on fork, the fork side of acting on tongue is controlled at square tongue and opens or locked position.On side's tongue the structure of accepting the escapement action is arranged.

4, discharge multidirectional dead bolt voluntary insurance simultaneously, above-mentioned dead bolt automatic blocking structure can be used in multidirectional locking, and discharges multidirectional dead bolt simultaneously and enters safety position automatically.As discharging the door top simultaneously, on the door limit, the three-dimensional dead bolt of student side.

Six, two-in-one driving chuck.Remove the transmission shaft tube of prior art, on dial, process a pair of flange, flange is replaced transmission shaft tube, realize the flexible connection of driving chuck and lock cover, move in the hole on the cover board with this.Two kinds of modes can be arranged: a kind of in-flanges, middle from dial to turning up, aperture on the aperture of inserting the transmission bar on the dial and the cover plate is can be the same big or more greatly, to reserve the movable desired position of transmission bar on the dial, the width of transmission this moment bar is decided by the size of cover board hole and dial flange, can be more smaller than cover board hole, and little 0.5 millimeter gets final product, bigger than the width between the dial flange both sides, can hold the degree that also can rotate freely to cover board hole or dial hole greatly.Can not be so also, no matter how structure changes, and the transmission bar of in-flanges structure, its width must be the width greater than the distance between the dial in-flanges both sides, or the structure of accepting the action of transmission bar is arranged in the dial hole.Another kind is a flanging, from dial outside to turning in, dig equally two flange come (certainly, no matter in-flanges, flanging can be that the flange of digging more than two comes, but with two for well.) with this flange is replaced transmission shaft tube.This moment, the width of transmission bar can decide according to the size and the action needs of transmission bar, also can with in-flanges one spline structure, or other suitable construction.

The present invention compared with prior art has following advantage: 1, remove the punching press lock core of frame, increased the stroke of blade, help improving tooth number.Supporting use double end blade, the anti-ability of dialling of drawing of increase tapered end had both improved performance, reduced cost again.2, variously anti-draw blade, improved anti-the drawing of blade lock widely and dialled performance.3, a hole multi-disc can be dwindled the lock core volume, increases the scope of application, can improve tooth number again.4, sleeve firmly is connected with anti-drilling layer, has strengthened the protective capacities of lockset self.Various methods of attachment are not only easy but also more reliable than originally.5, new key positioner method is simpler than original technology, and handling ease has reduced cost.6, tooth punching method is simpler than former technical matters, and percent defective is low, is particularly conducive to exchange and assembling.7, prior art can only make the commentaries on classics tongue be automatically locked in position, and the present invention can make all dead bolts be automatically locked in position, and structure is simpler.8, use driving chuck of the present invention to lack complex parts, and performance is reliable in the same old way, has saved product cost than former technology.
