Description

Lock body structure

Lock body structure technical field

It can increase the illegal lock body structure for opening difficulty the present invention relates to lockset, more particularly to a kind of can hide keyhole.Background technology

Existing machinery is locked（Such as all kinds of door locks, anti-theft lock for vehicle, electric door lock）It is primarily present two big defects.One, lock core keyhole it is exposed, make the core such as lock core of lockset, by exerting violence directly facing violent tool, lock core is easily twisted bad very much by the insertion keyhole such as electric drill, reamer and is opened or is broken or opened by the technical operation such as tinsel, sheet instrument by tamper tool.Secondly, when mounted lock body and installation hole be completely fixed, easily twisted bad lock core by the instruments such as reamer, screwdriver insertion keyhole and realized illegal unlatching very.Keyhole is exposed, and operating space convenient and spacious enough is provided for illegal unlock person, and lock body is fixed with lock cave, firm force application point will be provided when twisting and lock for illegal unlock person, prevents the poor performance illegally opened.All the time, lock core by strand, ignored in the industry always by this major issue, for lockset, this problem exactly lockset has unfruitful essential distinction, and reamer destruction lock core problem, such as media report, the Main Means used when to be that numerous stealers are actual steal are eager to need industry to be improved.Based on this two big defect, a variety of improvement lock body structures for being directed to each defect respectively are occurred in that.

Earlier, the lock body structure for hiding keyhole is occurred in that.A kind of anti-theft lock device as disclosed in Chinese patent 03203750. 3, as shown in figure 1, nappe of its one embodiment outside keyhole 60（Case shell) wears groove 61 inserted for key 30 is provided with, key 30 has handle 31, head 32 and inserted terminal 33 and L-shaped, and keyhole 60 is parallel with nappe.During unlocking, key 30 by jack 61 through be inserted into keyhole can Jian open.This kind of lock body can be hidden keyhole 60, large-scale violent tool is added unlocking difficulty by the limitation of operating space when twisting lock, prevent to some extent violent tool and pierce or insert keyhole and twist bad lock core and open lockset；On the other hand, because keyhole is not directly facing illegal unlock person, it is difficult to be found, adds the complexity of illegal unlock, theftproof performance makes moderate progress.

The lock body structure of other hiding keyholes, such as Chinese patent No. 94246161 and No. 96233262, also similar with aforementioned schemes, and lock body is hidden in door body, its keyhole is located at door body inner side and parallel with door-plate, provided with the opening for allowing human hand to stretch into unlocking on door-plate.This two scheme, can also hide keyhole, prevent large-scale reamer from twisting bad lock core to a certain extent.Have hiding keyhole scheme lock body being hidden in sleeve pipe again, as United States Patent (USP) 4584855 and Chinese patent 02232417 disclose such lock body structure, such lock body sets the larger open unlocked for human hand or key insertion on sleeve pipe, also can prevent large-scale reamer from twisting bad lock core to a certain extent.As for the scheme of other hiding keyholes, no longer lift in detail. But the lock body structure of foregoing hiding keyhole, following deficiency is still suffered from actual use, installation process：First, the installation of lock body needs the locked things such as the door face board with being used for disposing the lock or specific theftproof lock to make to coordinate, door could be formed to use or other use locking devices, the manufacture and application field for making lock body are restricted by the structure and design of locked thing, also brought to installation lock body compared with burden, and, above-mentioned each lock body can not form a kind of as easy to manufacture and independent general lock device, it is impossible to be widely used in simple and convenient each locking field, use occasion is restricted.

2nd, the cardinal principle of foregoing lock body is that lock body is hidden under a covering, increases unlocking difficulty by being difficult to find keyhole by illegal unlock person, to play a protective role.But illegal unlock person still can first destroy after covering and directly destroy lock body again, and the obstruction difficulty of illegal unlock is still little, can still be overcome by illegal unlock person, defencive function is not highly desirable.

3rd, more importantly, in aforementioned approaches case, the opening corresponding with keyhole is provided with the locked things such as covering OR gate plate, lock body and installation hole are still fixed simultaneously, the small-sized reamer of small-sized reamer, bottle opener particularly L-shaped can not be prevented to insert keyhole by the opening corresponding with keyhole at all, and further twist bad lock core and realize illegal unlatching, it is impossible to fundamentally solve the problem of lock core is easily twisted.

Correspondingly, people fix brought defect to solve lock body with installation hole, occur in that the lock body structure that lock core can be rotated freely, such as No. 99246767 Patent Cases of Chinese patent, it enables lock core to rotate freely on the basis of conventional lock construction, although the program can solve the problem that the destruction of reamer class instrument, but keyhole is still exposed, and the structure need to be directed to the dismounting and installation of tapered end in each locking and unlatching, operation is extremely difficult, it is difficult to actual use.And for example; Chinese patent 03223225 is proposed reaches the structure that non-key opening lock master can dally by changing lock core structure; but the improvement of such a lock core makes lock body structure sufficiently complex; and internal structure is easy to be destroyed or deformed by side force and lock core is difficult to the ability for being free rotation protection; and keyhole is still exposed; effect is unsatisfactory, it is impossible to easily realize the anti-strand function of lock core.

Aforementioned approaches case is taken a broad view of, in terms of lock body defect is improved, keyhole is exposed and lock body fixes two defects not by comprehensive improvement with lock cave, otherwise keyhole is hidden, but lock body is fixed with lock cave；Lock body can be rotated against with lock cave, but keyhole is still exposed, it is impossible to which the two is taken into account.The content of the invention

The technical problems to be solved by the invention are to provide a kind of lock body structure, and its lock body is easily fabricated, and independent general lockset can be made, and can be widely used in a variety of occasions, universal performance is good, meanwhile, the internal structures such as lock core can be played a protective role.

Another technical problem to be solved by this invention is to provide a kind of lock body structure, and it can thoroughly solve the problems, such as that the especially small-sized reamer of the violent tools such as reamer class twists bad lock core and causes the illegal unlatching of lock, and locking is extremely practical reliable. Another technical problem to be solved by this invention is to provide a kind of lock body structure, and it can increase illegal unlock difficulty, and theftproof performance is more preferable.

The technical scheme is that：A kind of lock body structure, including top lock, the top lock are arranged in an additional lock body with installation hole, and additional lock body is provided with the through hole passed in and out for dead bolt, and additional lock body is provided with and inserts the opening normally unlocked for key.Thus; enable lock body that independent general lockset is made by the specific modality of locked thing; can be with completely left out design iterations for each locked thing, installment work etc.; the all types of lockset finished products of the present invention are directly installed on to the corresponding reserved location of locked thing; universal performance is good; a variety of occasions can be widely used in, meanwhile, lock core can be played a protective role.

The top lock of the present invention（Pushlock, Chinese can be described as pressing lock）, it is an existing lock body structure independently used, it is axially entered along lock core by dead bolt or moves back to reach locking or open, different from common lock or cam lock, rotated while the rotation of top lock lock body, i.e. rotor are with stator, the locking or unlatching to being locked thing are not influenceed.It is contemplated that in the additional lock body of lock body outer cladding with solve versatility and it is many one layer protection the problem of; therefore; it is not specifically limited for the material of additional lock body, shape and concrete structure etc.; as long as the set that lock body is arranged at into tool installation hole is internal; protection scope of the present invention should just be belonged to; as for additional lock body either with or without coating lock body completely, how coating lock body etc., it is not restricted.

Further improve, it is in false fixation between top lock and installation hole to make, the bonding strength of the false fixation, between the twisting resistance that twisting resistance and lock core during lock body normally-open between key are twisted bad.In lock body normally-open by key, top lock is relatively fixed with installation hole, and in the case where lock body is by violence twist effect top lock can be made to be mounted opposite cave and dallied.

Compared to existing structure, although existing always using cam lock and making the hidden scheme of keyhole, but cam lock is as occurred lock body idle running also that is, the unlatching of lock, so can not consider to solve the problems, such as the anti-strand of lock core with whole lock body idle running mode in prior art, so as to form the usage of trade and technology prejudice for fixing tapered end in a position-stable manner.And the present invention makes false fixation between top lock and installation hole, top lock can be made to be mounted opposite cave in the case where lock body is by the effect of illegal external force and occur idle running protection, make the strength release completely of destruction tapered end and tapered end can not be acted on, generate a kind of unexpected technique effect of forefathers, overcome people in existing lock body design and installing area and think the technology prejudice that lock body and installation hole should be completely fixed simply, also change on the premise of assert that both must fix, by hiding keyhole, change lock core structure and lock core is occurred the usage of trade of idle running etc., the anti-technical barrier for twisting difference of pick-proof that tapered end exists always is solved in its simplest form.The present invention allows top lock to realize the weaker false fixation of intensity with installation hole, once lock core is false fixation because the stationary part of tapered end is relative with installation hole, can be allowed tapered end rotor by violent tool twist（Lock core part）Linked together and rotated simultaneously by the pellet in lock core with stationary part; tapered end is the function of protective idle running; make the strength release completely of destruction tapered end and tapered end can not be acted on; various large and small type reamer class instruments at all can not be twisted bad lock core and is opened; lock core is set to obtain basic safeguard protection The problem of lock core anti-strand can fundamentally be solved；And when normally-open by key, lock core rotor part can be rotated, and stationary part is still relatively fixed with tapered end installation hole, not interfere with normal unlocking.

Specifically, false fixed form is exemplified below：

Firstth, it is connected using top lock with the tensioner that installation hole is engaged side face, the mating surface between top lock and installation hole can be such as placed on by rubber sleave, plastic sheath, sheet metal or elastomer tensioner material to realize tensioner, but mentioned material is not limited to, other materials that can realize that tensioner is fixed all can be used.

Secondth, connection is held out against using axial limiting, material can be held out against by rubber sleave, plastic sheath, sheet metal or elastomer etc. and is engaged position in the inner face of top lock or outer face with installation hole and mutually holds out against, or is held out against by step or jump ring are spacing；Or do not use and hold out against material, and directly held out against by the inner face of top lock or outer face with the position that is engaged of lock body installation hole, certainly, this scheme needs installation hole outer end to provide the stress strong point to top lock.

3rd, using sicker adhesive-bonded form, sicker may be disposed at the side face or end face that top lock is engaged with installation hole, or be set simultaneously in side face and end face.As long as the two can be relatively fixed, sicker is not limited and is specifically bonded in where or bonding point quantity, but the bonding strength is no less than as the torsional moment produced by the normally-open lock body of key, to ensure that the normal of lock body is used.

4th, connected using elastic telescopic pin or frangibility pin.Elastic telescopic pin or frangibility pin radially can be located between top lock and the side face of installation hole, and at least one, or vertically between top lock and the end face of installation, preferably two.Wherein, frangibility pin is easier to destroy or fractureed in the case where twisting power effect than pellet in lock core；Elastic telescopic pin Xia twisting force Tui Shrink and tapered end is more freely rotated；Permanent pin is such as used, the side face for generally making it be resisted against lock under external force twist, can destroy this contact state and tapered end is dallied.

In the improvement project, essentially consist in the conventional design thinking for changing field of lockset, overcome the technology prejudice that the tapered end that people think always should be fixed with installation hole, and tapered end and installation hole are reached into antitheft purpose using a kind of weaker false fixation of intensity, therefore, as long as employing a kind of false fixation between tapered end and installation hole, and the bonding strength of the false fixation, between the twisting resistance that twisting resistance and lock core during lock body normally-open between key are twisted bad, protection scope of the present invention should just be belonged to, it is not limited to the foregoing several false fixed forms referred to, among prior art, other schemes that can realize false fixation can be used completely, protection scope of the present invention ought to be belonged to.

Further, the side in keyhole outwardly is provided with barrier structure, further to increase the difficulty of skilled unlocking.The barrier structure has a variety of implementation structures, and it can be radially distributed tubaeform catch or flexure strip or elastic yarn to be exemplified below-one, barrier structure.Also the second locking device can be provided with the outside of the tubaeform catch, control whether the tubaeform catch is rested in front of keyhole by second locking device, so as to realize what lock body was provided by additional lock body, idle running protection and barrier structure Multiple protection functions.It is general it is antitheft in the case of, such as employ in the case that keyhole hides and set barrier structure, will can be achieved a fixed connection between top lock and additional lock body installation hole.

2nd, barrier structure is the catch bar in front of keyhole, and the afterbody of the catch bar or side are in the direct or indirect of hand（Pass through other wisps）Promote lower pushing lock cylinder to enter and convenient lock operation is realized in the lock body of top, catch bar is provided with groove and key opening with additional lock body correspondence position, so that key can be by entering keyhole in the catch bar body.The catch bar can play a part of hidden and protection keyhole, and the further difficulty of increase technology unlocking and violence damage lock body as a slide mass.

3rd, the barrier structure is the 3rd individual lock on the outside of the lock of top, only first opens the 3rd individual lock, can just key is touched keyhole, can play multiple protection functions to lock body.

It is preferred that top lock can use indirect dead bolt.Indirect dead bolt is routine techniques, Bu Duoshu.Advantage using indirect dead bolt is that, by power load, and tapered end is not subject to the external force produced by locking when indirect dead bolt undertakes locking, it is ensured that tapered end and its interior lock core are hardly damaged.

It is preferred that additional lock body outer surface is provided with the outer sleeve body that freely can be rotated or slide relative to it, to prevent rainwater or dust from entering in additional lock body, outward opening is provided with the outer sleeve body position corresponding with additional lock body opening.

It is preferred that also including an electronic alarm device, the power switch that the mobile control electronic alarm device of dead bolt is locked by top carries out alarm, further increases antitheft prompt functions.

Foregoing all kinds of lock body structures of the invention, can be applied to antitheft door or rolling screen door or safe door or car door etc.；Or applied to U-shaped lock or chain lock or padlock or dish lock or automobile steering lock or protection defending lock etc.；Or tap or the locking of car rotary shaft or electric switch position or vehicle steering applied to bicycle or tricycle or electric bicycle or motorcycle, and lock body is fixed with locked vehicle as an entirety.As long as employing the solution of the present invention, it should also belong to protection scope of the present invention as other NM application scenarios.

It will be apparent that the present invention is not in addition to idle running protection is suitable for cam lock, other each schemes are applicable, and are no longer repeated, relative to prior art, it may have universal performance is good and effect of multiple protective.

In summary illustrate, the present invention has following beneficial technique effect compared with the prior art.

First, additional lock body and the tapered end of the present invention can be formed as an overall lockset and as final products or aftermarket product, enable the invention to that independent general lock body is made, and be widely used in a variety of occasions, and universal performance is good.In addition; keyhole is not exposed; lock core and dependency structure are concealed to greatest extent, and the opening of additional lock body only allows key turnover to realize unlocking, do not allow human hand to enter; space constraint can be played a part of; small-sized reamer insertion keyhole destruction lock core is reduced, after illegal unlock person's damage lock earnest, also needs to destroy additional lock body again; lock core, many one protective effects again could be destroyed.

2nd, lock body of the present invention has the function that protectiveness dallies with lock cave; even if small-sized electric drill, reamer etc. enter additional lock body; also it can be protected by the idle running of lock core and lock body can not be destroyed and be opened, can fundamentally prevent reamer class instrument from destroying lock core, theftproof performance is splendid. 3rd, the present invention sets barrier structure, further increases the difficulty of illegal unlock, anti-theft effect is good.Brief description of the drawings
