Description
Technical field
The utility model relates to a kind of lock body structure and application thereof that can stop lock core to be twisted; particularly the keyhole of top lock pin does not expose but in the supplementary protection body that has little opening that interior plant one is easy to make, belongs to various mechanical locks and composite lockset and manufacture and design the field.
Background technology
As everyone knows, various vehicle anti-thefts, door window antitheft, safety cabinet case are antitheft etc. relates to the person, safeguarding of assets aspect, and lock is a common tool.But the lock core keyhole (lockhole) of existing mechanical lock exposes, therefore enough operating spaces are provided, make the core of existing lockset, as lock core, directly face exerting violence of violent tool, thereby very easily twisted bad lock core by insertion keyholes such as electric drill, reamers and open lockset or broken by tamper tool or, open as tinsel, sheet instrument by technical operation.
For avoiding exposing the defective of being brought owing to keyhole, in the class patent application of (containing safe door), in application number 91103174, proposed lock core (or being called tapered end, lock gall) is hidden in the body but still vertical with the door face board scheme of lock core direction by Pan Biao, therefore, Key structure is inevitable complicated; Because the lock core direction is perpendicular to door face board, therefore, this structure makes makes complexity, Key structure also is unfavorable for actual use operation, therefore this technical scheme is difficult to realize actual use value, in addition, in order to install and fix lock core, also need use a knob structure that is exposed to the outer fixed lock core of lock body, therefore, another defective of this technical scheme is that it can not hidden fully structure relevant with lock core or parts, and the reason that causes this defective is because need lock core vertically is installed in the space of the reservation on the flush door panel, and fixed lock core.Just being valued for the safe door technical scheme that proposes in the application number 99257200 by Shen just changes the lock core direction into parallel with door face board; the unlatching of staight shank key for convenience; must leave a groove on the door face board before lock core hole, and the defective of groove structure is the lockhole that can not hide and protect lock core fully.And just be valued for application number 94246161 and opening in the hiding scheme that must remit the door lock core that in application number 96233262, proposes by Shen, with lock core keyhole direction towards parallel with door face board or inboard, but in order to make key enter keyhole easily, on door face board, must leave the opening that a staff can enter, because this opening enough big (allowing entering of staff), in fact for keyhole, formed the space of an opening, it can not actual realize that constraint uses small hand instrument (as little reamer) to twist bad the purpose of lock core by entering keyhole.United States Patent (USP) 3765199 has provided a kind of covering door lock engagement mechanism of giving prominence to outside door face board of installing outside the door lock hole, and leave a L shaped key in the side of nappe and insert mouth, the defective of this structure is because overburden is given prominence to outside door-plate, therefore destroyed easily, and the identical keyhole direction that remains with common installation method in lock core position is vertical with the door-plate face, also just can not really reach and avoid violence by destroying the purpose that lock core destroys lockset, and key insertion mouth can not be faced key user, inconvenient people's use.
United States Patent (USP) 4686840 discloses overburden protection lock core of padlock that utilizes L shaped opening and the structure that is equipped with L shaped key; but; this structure can not reach and stop L shaped reamer to enter the purpose that keyhole twists bad lock core from L shaped opening; and United States Patent (USP) 4584855 discloses common lock core has been hidden in an inside pipe casing; and utilize complicated structure to realize the unlatching of lock; this technical scheme has sleeve pipe upper shed excessive (for ease of normal key is put into keyhole with hand) can not prevent that violent tool from entering keyhole; and the defective that is difficult to make arranged; moreover; the lock core lock housing adopts pin to fixedly connected with sleeve pipe in this technical scheme; therefore violent tool can enter keyhole and twists bad lock core or utilize violence to rotate whole lock core and promptly can reach the purpose of unblanking; so this structure can not reach and stop L shaped reamer to enter the purpose that keyhole twists bad lock core or unblanks by the violence rotational lock core from its opening.Chinese patent ZL02232417.8 discloses the method that similarly lock core is hidden in the sleeve pipe, though this patent is in detail openly lock core structure and specifically mounting method not, but describe and the accompanying drawing structure decision according to it, this scheme has been used the turning-bolt lock lock core, utilized common pin fixed lock core and sleeve pipe or lock core and sleeve pipe have been pressed knot method together, therefore, this scheme can not stop by L shaped violent tool (as reamer) twist bad lock core (when the stationary part of lock core by firmly fixedly the time) rotational lock core or rotate lock housing reach the purpose of unblanking (when fixing with pin destroyed after), because for turning-bolt lock, the lock core rotor part can be rotated or the stationary part of lock core can rotate, and lock is to have entered opening so.Therefore, formerly technical scheme has mainly solved the problem that prevents technology unlocking by the method that limits key operated space, though formerly technical scheme can prevent the damage capability of large-scale violent tool to lock core effectively, but not solving violence fully unblanks, especially small-sized reamer class (as L shaped and key shape roughly the same little reamer mutually) can enter the problem that the broken lock of keyhole is unblanked, and the latter according to media reports, is to weigh the main way that adopts when many stealers are actual to be stolen.
Another defective of above-mentioned technical scheme formerly is that lock core is designed to be placed on the position of door face board, form the locking device of door usefulness, perhaps owing to use the turning-bolt lock structure, on the one hand, it is made and application is restricted by the structure of door-plate or turning-bolt lock and designing institute, on the other hand, technique scheme can not form the fabrication scheme of a kind of independence and lock device that can be general, and may be applied to other field.
Summary of the invention
Main purpose of the present utility model is to overcome technological deficiency formerly; provide a kind of more practical reliable; the lock body structure and the application process thereof that can stop lock core to be twisted that are easy to make and extensively are suitable for; especially be able to stop or make violent tool such as reamer by destroying lock core or violence rotational lock core or together with the method that lock core shell the rotates invalid lock body structure fully of illegally unblanking; this method can not expose lockset lock core keyhole; but be equivalent to be in the supplementary protection body; lock core combines by tensioner mode (no pin joint mode) relative fixed with additional lock body and forms a complete lockset; hide lock core and dependency structure to greatest extent; reach the purpose that greatly reduces the operating space of row robber person's violence damage or skilled unlocking, and make the twist action that lock is illegally opened.It is characterized in that have a little opening on the additional lock body, the top lock pin is installed in the described additional lock body, and the keyhole of top lock is towards additional lock body inside, lock with tensioner mode and the tight relative fixed of additional lock body on described top.
In order to realize the purpose of this utility model, adopt following technical scheme: the top lock pin is installed in and one has in the additional lock body of strip inner space (enable to satisfy lock core centerline direction with little opening along the corresponding to condition of sensing of adding the lock body long axis direction), have a little opening on the additional lock body and (only allow the turnover of key, but do not allow entering of staff, play the space constraint effect, with the effect that stops violent tool destruction lock core) as the outside eye that inserts of key, key has only by just reaching the unlatching of the entity keyhole realization lock on the lock core behind the little opening on the lock body, and lock core and additional lock body form as a whole lock as final products or accessory product; And key handle becomes L or T shape with the key bit handle so that the unlatching of lock, lock core adopts the lock of top lock construction, so-called top lock is disclosed as United States Patent (USP) 6523378, the top lock is defined as in the technical program: the lock construction that can independently use, its dead bolt marches forward or retreats along lock core shaft and reaches the purpose that locks or open, therefore, different with common lock or turning-bolt lock, the rotation of simple top lock lock body can not influence the locking or the opening of lock.Particularly, the lock body structure and the application thereof that can stop lock core to be twisted of the present invention has following main several modes, but is not limited only to the example of lifting:
First kind of mode is that the top lock pin is installed in the additional lock body of strip inner space vertically, additional lock body has the thin plate in the strip space that lock core is installed or cylindrical in the middle of can being, square column type or other any suitable shape are with suitable different application scenario, have a L shaped shape or other shaped aperture on the additional lock body, this plane of the opening is vertical with lock core keyhole end face or become big acute angle, but preferably become vertical, and the opening on the additional lock body is in positively biased the place ahead of lock core keyhole.Difficulty when further increasing technical opening, in additional lock body internal cylinder keyhole front, flaring flexure strip or catch can also be installed, and catch can be controlled it by one second locking device further and whether rest on the place ahead of aforementioned first keyhole (down together).Make L shaped in order to open the Key handle.At lock-out state, dead bolt is pushed out and enters in the dead bolt lock hole; In opening, in the lock housing of dead bolt withdrawal lock core.
