Description

The lock body structure and the mounting method that can stop lock core to be twisted

Technical field

The present invention relates to lockset, particularly relate to the lock body structure and the mounting method that can stop lock core to be twisted.

Background technology

Mainly there are two big defectives in existing machinery lock (as all kinds of door locks, anti-theft lock for vehicle, electric door lock etc.).The keyhole of one, lock core exposes, make the core such as the lock core of lockset, will be directly in the face of the exerting violence of violent tool, very easily twisted bad lock core by insertion keyholes such as electric drill, reamers and open or broken or opened by technical operation such as tinsel, sheet instrument by tamper tool.Two, lock body and installation hole are completely fixed when mounted, are very easily inserted keyhole by instruments such as reamer, screwdrivers and twist bad lock core and realize illegal unlatching.Keyhole exposes, and for the person that illegally do not unblank provides enough convenience and spacious operating space, and lock body and lock cave are fixed, and provide firm application of force application point in the time of will twisting lock for the person that illegally do not unblank, and prevent illegal poor performance of opening.Based on this two big defective, occurred multiple respectively at the improvement lock body structure of each defective.

Early, the lock body structure that keyhole is hidden has appearred.As No. 03203750.3 disclosed a kind of anti-theft lock device of Chinese patent, as shown in Figure 1, be provided with on the nappe (case shell) of an one embodiment outside keyhole 60 for what key 30 inserted and wear groove 61, key 30 has handle 31, head 32 and inserted terminal 33 and is the L type, and keyhole 60 is parallel with nappe.When unblanking, key 30 is passed by jack 61 and inserts keyhole again and just can open.This kind lock body can make keyhole 60 be hidden, and makes large-scale violent tool be subjected to the restriction of operating space and increase unlocking difficulty in when lock strand, has prevented that to a certain extent violent tool from piercing or inserting keyhole and twist bad lock core and reach and illegally unblank; On the other hand, directly do not face the person that illegally do not unblank because of keyhole, be difficult for being found, even illegally do not unblanked person's discovery, also need to destroy earlier nappe and could destroy lock body again, increased the complexity of illegally unblanking, theftproof performance makes moderate progress.But because of the cardinal principle of this lock body is that lock body is hidden under the overburden, the person that illegally do not unblank still can destroy overburden earlier and destroy lock body again, and defencive function is not really desirable.The more important thing is, this lock body only exposes at keyhole has taked solution, lock body and installation hole remain fixing, though can prevent to a certain extent that large-scale reamer from twisting bad lock core, can not stop the particularly L shaped small-sized reamer of small-sized reamer, bottle opener to insert keyhole and twist bad lock core and realize illegal unlatching.

The lock body structure of other hiding keyhole, also similar as Chinese patent No. 94246161 and No. 96233262 with aforementioned schemes, lock body is hidden in the body, it is inboard and parallel with door-plate that its keyhole is positioned at a body, is provided with to allow staff to stretch into the opening of unblanking on door-plate.This two scheme, also keyhole can be hidden, prevented that to a certain extent large-scale reamer from twisting bad lock core, but because of its opening enough big, basically formed an open space, and lock body and lock cave are fixed, and can allow small-sized reamer, screwdriver be entered and inserted keyhole by opening fully and twist bad the illegal unlatching of lock core realization, and preventing destructing performance is not good.Have again lock body is hidden in hiding keyhole scheme in the sleeve pipe, disclose this type of lock body structure as United States Patent (USP) 4584855 and Chinese patent 02232417, such lock body is provided with on sleeve pipe for staff or key and inserts the big opening of unblanking, and lock body and lock cave are fixed, and can not stop small-sized reamer, bottle opener to be entered by opening equally and twist bad lock core and realize illegal the unlatching.As for the scheme of other hiding keyhole, no longer detailed the act.

For solving the fixing defective of being brought of lock body and installation hole, the lock body structure that lock core can freely rotate has appearred, as No. 99246767 patent cases of Chinese patent, it makes lock core rotate freely on the basis of conventional lock construction, though this scheme can solve the destruction of reamer class instrument, keyhole still exposes, and this structure needs all to relate to the dismounting and the installation of tapered end when each locking and unlatching, operate very difficultly, be difficult to actual use.And for example; Chinese patent 03223225 has proposed to reach the structure that non-key operated lock core can dally by changing lock core structure; but the improvement of this kind lock core makes complex structure; and internal construction is easy to be destroyed by lateral force or is out of shape and makes lock core be difficult to be the ability of free rotation protection; and keyhole still exposes, and effect is unsatisfactory.

Take a broad view of the aforementioned approaches case, improving aspect the lock body defective, keyhole exposes and lock body is fixed two defectives not by omnibearing improvement with the lock cave, or keyhole is hidden, but lock body with lock the cave and fix; Lock body can rotate relatively with the lock cave, but keyhole still exposes, and can not the two take into account.

In all aforementioned approaches cases, the scheme that keyhole is hidden can prevent to a certain extent that large-scale violent tool from directly destroying lock core, but do not solve the problem that violence is unblanked fully, especially small-sized reamer class instrument (as L shaped or with the similar little reamer of key shape) can enter the problem that the broken lock of keyhole is unblanked; And lock core is relative with the lock cave can the scheme of idle running in, be not to use operation very complicated, be exactly that lock body structure is very complicated, can not realize easily that lock core prevents the strand function.All the time, lock core is ignored in the industry by this major issue of strand always, does not see the use of Related product in practical application.For lockset, this problem lockset just has unfruitful essential distinction, and reamer destroys the lock core problem, as media report, and the main means that adopt when being the actual theft of numerous stealers, the need industry of being eager is improved.

Another defective of all aforementioned schemes is: the installation of tapered end need be done to cooperate with locked thing such as the door face board that is used for settling this lock or specific theftproof lock, could form the door with or other use locking device, the manufacturing of lock body and structure and designing institute that application is subjected to locked thing are restricted, bring than burden also for the installation lock body, and above-mentioned each lock body can not form a kind of conduct and make easily and independent general lock device, can not be widely used in to simple and convenient each locking field.

Summary of the invention

Technical problem to be solved by this invention provides a kind of lock body structure and mounting method that can stop lock core to be twisted, can thoroughly solve owing to violent tools such as large and small type reamer class twist bad or the twist lock core causes the illegal unlatching problem of locking, lock more practical reliable.

Another technical problem to be solved by this invention provides a kind of lock body structure that can stop lock core to be twisted, and lock body is easy to make, and can make independent general lockset, can be widely used in multiple occasion, and universal performance is good, simultaneously, can play a protective role to lock core.

A technical problem more to be solved by this invention provides a kind of lock body structure that stops lock core to be twisted, and it can increase illegal unlocking difficulty, and theftproof performance is better.

Technical scheme of the present invention is: a kind of lock body structure that can stop lock core to be twisted comprises the top lock that is arranged in the installation hole; Be false fixing between top lock and the installation hole, this is false to be fixedly coupled between the twisting resistance and the twisting resistance that twisted bad of lock core of intensity when key is normally opened lock body.

In the prior art, exist and use turning-bolt lock and make the hidden scheme of keyhole, and turning-bolt lock also promptly is equivalent to the unlatching of locking as lock body idle running takes place, so can not consider in the prior art scheme to solve the anti-strand problem of lock core, thereby form with the fixed form fixedly usage of trade and the technology prejudice of tapered end with the mode of whole lock body idle running.And adopted the false form of fixedlying connected between top of the present invention lock and the installation hole; be subjected to make under the violence twist the relative installation hole of top lock that the idle running protection takes place at lock body; the strength of destroying tapered end is discharged fully and tapered end can not be acted on; make the saboteur powerless; produced the unexpected technique effect of a kind of forefathers; overcome in design of existing lock body and the installing area people and thought the technology prejudice that tapered end and installation hole should be completely fixed simply; also changed under the fixing prerequisite of lock body and installation hole; by hiding keyhole; change lock core structure and make lock core that the industry design custom of idle running can take place, solved the technical barrier that pick-proof that tapered end exists always prevents twisting poor performance in the simplest mode.

The present invention is by allowing top lock and installation hole realize false the fixing that intensity is more weak; in case lock core is by the violent tool twist; because of the stationary part of tapered end is relative with installation hole is false fixing; can allow tapered end rotor (lock core part) and stationary part to link together by the pellet shot from a slingshot in the lock core rotates simultaneously; tapered end promptly has the function of protectiveness idle running; the strength of destroying tapered end is discharged fully and tapered end can not be acted on; make various big; small-sized reamer class instrument can't twist bad lock core and open at all; make lock core can obtain basic safeguard protection; can prevent fundamentally that lock core from being twisted; thoroughly solve antitheft problem; and when normally opening by key; lock core rotor part can be rotated, and stationary part still with tapered end installation hole relative fixed, can not influence normally and unblank.

Top lock (pushlock disclosed in this invention, Chinese can be described as pressing lock) for having lock body structure now, its by dead bolt along lock core shaft to advancing or move back to reach locking or open, be different from common lock or turning-bolt lock, the rotation of top lock lock body, rotate when being rotor and stator, do not influence locking or unlatching locked thing.

Particularly, the false fixed form that lock body structure of the present invention adopted is exemplified below:

The first, adopt the match tensioner of side face of top lock and installation hole to be connected, connect false the fixing of frictional force realization that is produced by tensioner.Can place the fitting face between top lock and the installation hole to realize tensioner by tensioner material sleeve such as rubber sleave, plastic sheath, sheet metal or elastic bodys, but be not limited to mentioned material, other can realize that the fixing material of tensioner all can use; Obviously, also can not adopt the tensioner material, realize transition, interference fit between top lock and the installation hole, also can realize false fixing and directly make.

The second, adopt axial limiting to hold out against connection, can hold out against material by rubber sleave, plastic sheath, sheet metal or elastic body etc. and hold out against mutually with the installation hole position of matching in the inner face of top lock or outer face, or by step or jump ring is spacing holds out against; Or do not adopt and hold out against material, and directly hold out against with the position of matching of lock body installation hole by the inner face or the outer face of top lock, certainly, this scheme needs the installation hole outer end to provide the stressed strong point to the top lock.

Three, adopt the sicker adhesive-bonded form, sicker can be arranged at a side face or the end face that the top lock matches with installation hole, or is provided with simultaneously in side face and end face.As long as can make the two relative fixed, do not limit sicker and where specifically be bonded in or bonding point quantity, bonding strength should be less than the twisting resistance of normally opening lock body by key and being produced, to guarantee the normal use of lock body.

Four, adopt elastic telescopic pin or frangibility pin to connect.Elastic telescopic pin or frangibility pin can radially be provided with along lock core, and are at least one; Or be located at vertically on the end face between top lock and the installation hole, be preferably two.Wherein, the frangibility pin under violence twist effect than lock core in pellet shot from a slingshot be easier to destroy or fracture; The elastic telescopic pin is shunk back under twisting force and tapered end can be rotated more freely.

Need illustrate; the present invention mainly is to have changed the conventional design thinking of field of lockset; overcome the technology prejudice that tapered end that people think always and installation hole should be fixed; and adopt more weak false of a kind of intensity fixedly to reach antitheft purpose tapered end and installation hole; therefore; need only and adopting intensity normally to open the twisting resistance of lock body and false the fixing between the ruined twisting resistance of lock core between tapered end and the installation hole between key; just should belong to protection scope of the present invention; be not limited to the aforementioned several false fixed form of mentioning; in the prior art; other can realize that false fixing scheme can adopt fully, and should belong to protection scope of the present invention.

Preferably, the top lock is arranged in the additional lock body, this additional lock body is provided with installation hole and realizes described false fixing with the top lock, and additional lock body is provided with the opening that only inserts for key in the position relative with top lock keyhole.

By this additional lock body, on the one hand keyhole is not exposed, lock core and dependency structure have been hidden to greatest extent, because of the opening that adds lock body only allows the key turnover so that unblank, play the effect of space constraint, can stop small-sized violent tool to insert keyhole, reach the purpose that reduces stealer violence damage or skilled unlocking operating space, lock core is played double protection by this opening; Prior, additional lock body and tapered end of the present invention can form as a whole lockset and as final products or accessory product, make the present invention can make independent general lockset, the corresponding reserved location that can directly all types of lockset finished products of the present invention be installed on locked thing gets final product, can save design iterations at each locked thing, installation work or the like fully, universal performance is good, can be widely used in multiple occasion.

Preferably, be provided with barrier structure in the keyhole outside, with the difficulty of further increase skilled unlocking.For this barrier structure, multiple enforcement structure is also arranged, be exemplified below:

One, barrier structure can be tubaeform catch or flexure strip or the elastic yarn that radially distributes.Further; be provided with second locking device in the outside of this tubaeform catch; whether rest on keyhole the place ahead by second locking device control this tubaeform catch, thereby realize lock body and installation hole can dally, keyhole hiding, handicapping keeps off the multiple protection functions that structure provided.Under general antitheft situation, as adopted keyhole hide and barrier structure after, also can adopt permanent pin to fixedly connected with between tapered end and the installation hole.

Two, barrier structure is to be installed in the catch bar that can be free to slide or can slide and rotate simultaneously before the keyhole, the afterbody of this catch bar or side promotion lock core under direct or indirect (by other wisp) of hand promotes enters realizes lock operation easily in the lock of top, catch bar and additional lock body correspondence position have groove and key opening, so that key can be by entering keyhole in this pusher body.This catch bar can play effect hidden and the protection keyhole as a slide mass, further increases the difficulty of skilled unlocking and violence damage lock body.

Three, described barrier structure is the 3rd independent lockset in the lock outside, top, has only and opens the 3rd independent lockset earlier, just can make key touch keyhole, can play the triple protection function to lock body.

The lock body structure of aforementioned approaches case of the present invention can be applicable to security door or rolling door or safe door or automotive door or the like; Or be applied to U-shaped lock or chain lock or padlock or dish lock or automobile steering lock or protection defending lock or the like; Or be applied to the locking of tap or car turning cylinder or the electric switch position or the vehicle steering of bicycle or tricycle or electric bicycle or motorcycle, and make lock body become as a whole with locked vehicle stationary.As long as adopted the solution of the present invention, also should belong to protection scope of the present invention as for other NM application scenario.

The present invention also provides a kind of lock body mounting method that can stop lock core to be twisted, be set to a kind of false fixedlying connected with between top lock and the installation hole, this is false to be fixedly coupled between the twisting resistance and the twisting resistance that twisted bad of lock core of intensity when key is normally opened lock body.When key is normally opened lock body, top lock and installation hole relative fixed, and be subjected to making under the violence twist effect lock relative installation hole in top to dally at lock body.Can prevent fundamentally that reamer class instrument from destroying lock core, theftproof performance is splendid.

The specific embodiment

Embodiment 1

As shown in Figure 2, lock body structure of the present invention, comprise the top lock 1 (pushlock that is arranged in the installation hole 2, Chinese can be described as pressing lock), installation hole 2 is surrounded by limit wall 21, and the interior (not shown) of lockhole that dead bolt 11 inserts locked thing locks, and is false fixing between top lock 1 and the installation hole 2, this is false be fixedly coupled intensity a little less than, between the twisting resistance that twisting resistance when key is normally opened lock body and lock core are twisted bad.Referring to Fig. 2 A, normally open the twisting resistance of lock body by key, in normal twisting resistance scope T1～T2, and the lock core of lock body 1 also has an antitorque or anti-strand scope T3～T4, false fixing can choosing between these two scopes of the present invention.Best, this false strength of fixation T is between the minimum twisting resistance T3 that is normally opened lock body producible maximum twist power T2 and lock core by key, and between this scope, the lock body performance is the most stable; Certainly, bonding strength T also can be between T1 and T4; Or between T2 and T4; Or between T1 and T3.This is false fixing, can be embodied as top lock 1 simply and cooperate the tensioner of side face to be connected with installation hole 2, and the frictional force that is produced by the tensioner effect realizes false fixing, and the frictional force torque should be less than normally opening the torsional moment that lock body 1 is produced by key.Can realize tensioner by the fitting face that tensioner materials 34 such as rubber sleave, plastic sheath, sheet metal or elastic body are placed between top lock 1 and the installation hole 2; Certainly, also can directly realize false fixing by the transition between top lock 1 and the installation hole 2, interference fit.Of the present invention false when fixedly making key normally open lock body, top lock 1 and installation hole 2 relative fixed, and be subjected to make under the effect of illegal external force twist keyhole 13 1 relative installation hole 2 idle running of top lock at lock body, can not twist bad lock core, lock body can not be opened, the antitheft problem of anti-strand of existing lockset can be thoroughly solved.

As shown in Figure 3, this is false fixing also can to adopt axial limiting to hold out against connection, and axially the frictional force that produces on end face of pressure should be less than the torsional moment of normally opening lock body by key and being produced.Can cooperate installation hole 2 outer ends the stressed strong point to be provided for top lock 1, hold out against material 35 by rubber sleave, plastic sheath, sheet metal or elastic body etc. and hold out against with the position of matching of installation hole 2, also can hold out against by outer face 12 and installation hole 2 limit walls 21 at the inner face 10 of top lock 1.Preferably, stopper section 22 is established in installation hole 2 outer ends, is extracted by external force to prevent top lock 1, or is connected in order to hold out against with the outer face 12 of top lock 1; This stopper section 22 can be one-body molded with limit wall 21, as shown in Figure 3; Or make stopper section 22 and limit wall 21 adopt bonding, screw togather, tight fit etc. removably connects, shown in Fig. 4,5, so that tapered end 1 is installed.As shown in Figure 6, this axially holds out against also and can make top lock 1 unlikely mobile vertically by step or jump ring 40 spacing holding out against.

As shown in Figure 4, also can be false fixing by sicker 36 bonding realizations, sicker 36 can be arranged at the side face that top lock 1 matches with installation hole 2, also can only be located at the inner face or the outer face of the two cooperation, also can be provided with simultaneously in side face and end face.

As shown in Figure 5; false fixing also can be realized by plastics pin or frangibility pin 37; the intensity of pin 37 is less than the equal pin by pellet shot from a slingshot material manufacturing in the lock core; in Fig. 5; be provided with two in endface position vertically; when the foreign compulsion lock core rotates; plastics pin or frangibility pin 37 were promptly fractureed before lock core is destroyed; so that tapered end idle running protection; when having non-cylindrical periphery face, also can only be provided with one, when external force twist lock core along end face axial as pin 37; shearing force will be destroyed non-cylindrical periphery face and make its slyness, make lock body 1 idle running.Obviously, this pin 37 also can radially be located between tapered end 1 and the installation hole 2, can only establish one.This pin 37 also can be replaced by elastic telescopic pin 38, and as shown in Figure 3, when external force twist lock core, elastic telescopic pin 38 is made elastic yield so that tapered end 1 dallies.

Further improve, the external surface of top lock 1 (inner face 10 or outer face 12 or outer peripheral face) is provided with in order to increase the tiny protuberance of frictional force, so that reach false fixing needed intensity, no longer provides graphic.

Embodiment 2

Referring to Fig. 6, this embodiment is on the basis of embodiment 1, installation hole is located in the additional lock body 4, additional lock body 4 is provided with for the through hole 43 of dead bolt 11 turnover and the opening 42 that inserts for key, top lock 1 is arranged in the installation hole 41 of this additional lock body 4, and between installation hole 41 and top lock 1, reach false fixing, adopt tubular step (or rectangle step or step of forming by interior card) 40 realizations axially to hold out against connection among the figure, certainly, it is false fixing also can to adopt elastic telescopic pin 38 to realize.Additional lock body 4 can be made of the thin plate of tool strip installation hole; or constitute by the leather sheath pipe; its material can be selected from metal; high molecular polymer; wooden or tempered glass or the like; for the bigger additional lock body of metal equal strength; can play better protection to the lock core in it; the profile of additional lock body 4 can be cylindrical or square column type or other any suitable shape; with suitable different application scenario; additional lock body 4 two ends can be sealed; disguise with further increase tapered end 1; certainly additional lock body 4 also can make one or both ends uncovered, so that the lock body installation, as shown in figure 11.

In addition, also the installation hole that installs the top lock among the embodiment 1 can be done as a wholely, further be located in the additional lock body, between two installation holes, adopt to be completely fixed or false fixed form connects, more can many one decks protections, no longer provide graphic.

As shown in Figure 6, only on the relative side of the keyhole 13 of additional lock body 4 and top lock 1, be provided with opening 42 for the key insertion; The end face at the plane at these opening 42 places and keyhole 13 places is not parallel, and best plane of the opening is vertical with lock core keyhole end face or become big acute angle, but is vertical best, and the opening on the additional lock body 4 42 is in positively biased the place ahead of keyhole 13.

This opening 42 preferably adopts the slice shape, so that entering easily, adds in the lock body 4 by key, and the opening space of as far as possible reducing lock core 13; This opening 42 can be in-line (as shown in figure 11), at this moment, as shown in Figure 7, lock core should adopt key 5 to insert keyhole 13 and mention top lock pin 1 structure of promptly opening slightly, key 5 can be L shaped, have key bit 51, key bit handle 52 and key handle 53,, must press the trend shown in the figure when key 5 is opened lock core with the unlatching of convenient lock; In addition, opening 42 can be shown in Figure 6 L shaped, and the long end parts of L shaped opening makes key 5 can enter additional lock body 4 smoothly, and the other end makes the L shaped key 5 that inserts keyhole 13 can rotate an angle and opens lock core; Certainly, also can be as shown in figure 16, this opening 42 also can be the L type that an end has circular arc.Insert as long as be convenient to key, be not limited to the opening form of mentioning.

Certainly, also can make opening 42 deflection the place ahead, at this moment at keyhole 13, key 5 must just can enter keyhole 13 according to trend shown in Figure 8 when opening lock body, and key 5 optimum shapes are three-dimensional two L shaped, and promptly two L types have additional teeth handle 521 not on same plane.

When unblanking, as shown in Figure 6, L shaped key is partly inserted the keyhole 13 of lock core along the transverse opening of L shaped opening 42, key 5 handle portions 53 turn to and enter the longitudinal opening of L shaped opening 42, but cause top lock pin 13 to enter opening, when key handle 53 rotates when returning the transverse opening of L shaped opening 42 again, top lock pin 1 together with key 5 under the effect of contained spring 14 in lock housing (stationary part of lock core) fall back on the opening of lock fully, and key 5 promptly can take out from transverse opening.

In this embodiment; keyhole 13 does not expose; can play the effect of space constraint; can stop small-sized violent tool to insert keyhole 13 and destroy lock core, lock body 1 be played double protection, even small-sized reamer can insert keyhole 13 by this opening 42; to there be complete real fixed because of the installation hole 41 of tapered end 1 and additional lock body 4 yet; and when keyhole 13 during by the twist of reamer class instrument, tapered end 1 can be in additional lock body 4 skid, fundamentally protect the lock core in the tapered end 1 not to be destroyed.And additional lock body 4 can form as a whole lockset with top lock 1, and makes simple and easyly, and universal performance is good.

As shown in Figure 6, for further increasing the difficulty of skilled unlocking, lock core keyhole 13 fronts in additional lock body 4 also are provided with barrier structure.As can be flaring flexure strip or catch 54, further, this flexure strip or catch 54 are controlled the place ahead whether it rests on keyhole 13 by another second locking device, so that lock body 1 is made triple protection, omit diagram.
