Description

A kind of double-inserting type antitheft door

Technical field

This utility model relates to anti-theft safety door field, is specifically related to a kind of double-inserting type antitheft door。

Background technology

Antitheft door is mainly made up of doorframe, door leaf, locking mechanism, and wherein, locking mechanism includes lockset, driving member, dead bolt or locking bolt。Comprising driving device in lockset, driving device is divided into again the modes such as lock core type of drive, handle type of drive and driven by power by the difference of executive mode。Doorframe is provided with several doorframe jacks, and lockset driving device drives dead bolt, locking bolt insert in doorframe jack or extract out from which by driving member, in order to complete turning off or on of antitheft door。

The shortcoming of lock core type of drive is that over-burden for key, and namely key suffered resistance in rotary course is excessive, and lock point is more many, and resistance is more big。By the restriction of lock core structure, the limited mechanical strength of key, often there is key torsional deflection, ftracture even breakage phenomenon。So, when key band movable lock core drives, dead bolt, locking bolt shift motion all little, such as main dead bolt extension elongation mostly is 20～30 millimeters, secondary lock (or other lock point) dead bolt extension elongation mostly is 16～20 millimeters, dead bolt diameter 16～18 millimeters and mostly be hollow-core construction, and purpose is and alleviates resistance suffered by key, its cost is the range reducing dead bolt, have impact on the anti-of antitheft door and pries open performance。The advantage of handle type of drive is that driving force is sufficiently large, and the range of dead bolt can increase more than 1 times, can extend key long service life significantly simultaneously, bring convenience for user, but handle itself is easily taken as the target of attack do not locked of forcing open the door。

When antitheft door is prized, the dead bolt inserting doorframe is equivalent to cantilever beam, and the counteracting force of dead bolt is made dead bolt be subject to two kinds of active forces by doorframe: one is shearing force, and two is moment of flexure。For shearing force, as long as the intensity of dead bolt includes the diameter of solid dead bolt or the wall thickness of hollow dead bolt, material performance index all reach relevant criterion requirement, namely can guarantee that dead bolt will not gross distortion or cut off；For Moment, the dead bolt of general main lock lockset and lock body are disjunctors, are installed on door leaf side, and there is situation about directly contacting the lock body side exposed with the instrument of forcing open the door, therefore easily suffers local damage。Additionally, the fixed form majority of main lock lockset and door leaf adopts 4 screws to be fixed on by lock body on door leaf side, lock core is inserted from the preformed hole of the inside and outside panel of door leaf lock body again, again with 1 stay bolt from laterally the two being fixed, the outer side panel of lockset, inner panel are buckled in door leaf both sides respectively, fix from door leaf inboard with long spiro nail again, the outer side panel of lockset now exposes the end of lock core。Outside protruding from door leaf outer panels due to the outer side panel of lockset, it is easy to destroyed, destroying rear lock core and lock body is only fixed with door leaf side, become cantilevered fixed form, opposing destructive characteristics becomes more weak。Door leaf outer panels is installed lockset place and is had multiple preformed hole, and aperture is also big, has a strong impact on the preventing destructing performance of antitheft door and lockset。Secondary lock (or other lock point) is generally adopted 2 screws with door leaf side and is fixed on door leaf side, also belongs to cantilever structure, and the performance such as collapse resistance, pick-proof is also unreliable。

Door leaf many employings cold-reduced sheet extruding, bending, it is welded。When the steel plate of door leaf is rich, material is poor, door leaf skeleton and when reinforcement protection Design is not in place, layout is unreasonable, door leaf is easy for deforming, and is extracted out by dead bolt by force and will be pried open by door leaf from doorframe jack, and especially dead bolt is more short, more easy is pried open。So, for making dead bolt and doorframe jack be connected firmly, prior art has multiple improved procedure: what have stretches out rear 90-degree rotation angle by dead bolt, and the protruding parts of the length direction of dead bolt termination is stuck on the width of doorframe jack, stop dead bolt to be drawn out of；Have dead bolt is stretched out after, the length direction of dead bolt termination has two rotatable member to be flared out and locking, then dead bolt entire card is on the length direction of doorframe jack；What also have is provided with semi-circular dead bolt, and rotation is hooked on upper and lower two doorframe jacks that doorframe is corresponding etc. behind turnback angle。Above-mentioned locking mechanism all makes running resistance increase, and some Local Null parts mechanical strength reduces, and population structure is complicated simultaneously, and cost improves, and stability, reliability are also not ideal。

Summary of the invention

For solving the problems that above-mentioned antitheft door preventing destructing performance aspect exists, this utility model provides a kind of double-inserting type antitheft door, with brand-new General layout Plan and special construction, overcome many drawbacks of existing antitheft door, its collapse resistance, anti-pry open performance and be obviously enhanced, and simple in construction, with low cost。

This utility model adopts the following technical scheme that a kind of double-inserting type antitheft door, and including doorframe, door leaf, locking mechanism, wherein, a vertical plane of doorframe is provided with doorframe jack from top to bottom, and it is adjacent and vertical that limit buckled by this vertical plane doorframe the most inboard with doorframe。Door leaf comprises door leaf outer panels, door leaf wainscot and door leaf side, and locking mechanism includes lockset, driving member and dead bolt, and the driving device of lockset drives dead bolt insert in doorframe jack or extract out from which by driving member, in order to complete turning off or on of antitheft door。Major measure is: doorframe is buckled corresponding each doorframe jack position on limit and all fixedly mounted 1 in flat slotting ear, each slotting ear is parallel with the vertical plane of doorframe jack place doorframe, and keep at a certain distance away, the opening of the plug in ear clip seam that the two is formed is towards outdoors, each slotting ear all has 1 slotting ear jack, and with corresponding doorframe jack coaxial inner conductor。On door leaf side, corresponding doorframe jack has the door leaf side jack of equal number, longitudinal plate of door leaf internal next-door neighbour door leaf lateral location one vertical direction of fixed installation, the rectangular planar portion of the next-door neighbour door leaf medial surface side of this longitudinal direction plate is double; two plate, and this pair of plate is vertical with door leaf wainscot。One side of double; two plates contacts with the inner surface of door leaf side and fixedly mounts, on double; two plates, corresponding each door leaf side jack also respectively has 1 double; two plate jack in same position from top to bottom, another side of double; two plates corresponding each pair of plate jack from top to bottom all fixedly mounts 1 liner plate in channel-section steel shape, each liner plate middle part all has 1 liner plate jack, each liner plate jack and corresponding double; two plate jacks, the equal coaxial inner conductor of door leaf side jack。1 direction narrow slit type jack vertical with door leaf wainscot is also formed between each liner plate with double; two plates, being close to the corresponding each narrow slit type jack in door edge position on door leaf wainscot and be equipped with 1 rectangle jack, each rectangle jack is all overlapping with corresponding narrow slit type jack centrage in the vertical direction and width is identical。After door leaf cuts out, each slotting ear all can be removably inserted in rectangle jack and the narrow slit type jack of correspondence, double; two plates are also inserted in each plug in ear clip seam together with door leaf side simultaneously, now each self-corresponding liner plate jack, double; two plate jack, door leaf side jack, insert ear jack, doorframe jack totally 5 equal coaxial inner conductors in hole, i.e. concentric five jacks of each self-forming one group, and each dead bolt all can be removably inserted in one group of concentric five jack of correspondence under the driving of the driving device of lockset, in order to locking anti-theft door。

Door leaf is because of the installing additional of longitudinal plate, fixing, and door leaf resistance to deformation intensity significantly increases, and is especially easiest to suffer side, the door limit more resistance destroyed of forcing open the door。When the transverse section of longitudinal plate is linear or step-like or fold-line-shaped or comprise shaped form and during with the form fit of door leaf side, the opposite side edge relative with double; two plates of longitudinal plate contacts with the inner surface of door leaf outer panels, is welded and fixed。When after the transverse section of longitudinal plate increases a part again and bends, namely entirety is in angle shape, longitudinal plate side parallel with door leaf outer panels is fixedly welded on door leaf outer panels inner surface, longitudinal plate planform now, especially the part except double; two plates is while mating with door leaf side, set up the shapes such as knuckle, fin, step more, bending strength and the rigidity of longitudinal plate can be increased substantially, and then the integral rigidity of lifting antitheft door, when forcing open the door, door leaf side local deformation is also less。

Slotting ear on doorframe inserts in the narrow slit type jack of double-layer plate composition of door leaf, and slotting ear can be followed door leaf side synchronization trace in the process of forcing open the door and be moved, as long as dead bolt is not return, cut constantly, door leaf is not just opened。Meanwhile, double; two plates and door leaf side are also inserted into inserting in ear clip seam, jointly prevent the deformation of door leaf side and deviate from from crack, thus anti-pry open, preventing destructing performance significantly improves。Inserting ear to insert in narrow slit type jack, meanwhile, double; two plates insert in stitching to plug in ear clip, namely described " double-inserting type "。

Further, the dead bolt inserting concentric five jacks adopts round end cylindrical masses structure。Due to the insertion of dead bolt, when inserting ear under tension, insert double; two plates of ear both sides, liner plate opposite direction simultaneously and hold slotting ear, again because of narrow slit type jack narrower width, so dead bolt is limited primarily by shearing force。In like manner, double; two plates are also inserted into inserting in ear clip seam, during double; two plate under tension, the slotting ear of double; two plate both sides, doorframe steel plate hold double; two plate simultaneously, the width plugging in ear clip seam is also narrower, dead bolt herein is also limited primarily by the effect of shearing force, so dead bolt is suitable for selecting entity structure, and the dead bolt of small diameter also has enough intensity。Meanwhile, the diameter of dead bolt is more little, and the length inserting ear is more little, and each jack size on doorframe, door leaf is also more little, and then each region of interest mechanical strength is more big, and anti-damage performance is more strong。Dead bolt is that round end is cylindrical, and processing technique is simple, cost is low, is also convenient for inserting in concentric five jacks。

In concentric five jacks, each jack is shaped as circular hole or square hole or rectangular opening or slotted hole。It is true that 5 jacks are as being the circular hole of same diameter or during with the square hole of the length of side, fit-up gap and requirement on machining accuracy are higher, and especially door body deformation, door leaf sink, and 5 jacks easily occur dislocation in the vertical direction, affects inserting smoothly of dead bolt。Part jack adopts vertical direction to be slotted hole or the rectangle elongated hole of length direction, then fit-up gap allowable error at least in the vertical direction is relatively large, but has no effect on the locking performance of antitheft door。

Further, the tip shapes inserting ear is circular arc, it is simple to is inserted in rectangle jack and narrow slit type jack, avoids scratch human body simultaneously, scratches medicated clothing。

Further, when the medium position of double; two plates installs the main lock of mechanical lock, this medium position also has and the main rectangle installing hole that mate of lock, and described each group of concentric five jacks are distributed in door leaf, the middle and upper part of doorframe or middle and lower part, and mates with the dead bolt of corresponding lock point。

In prior art, most main locks are arranged on the middle part of door leaf side, in this case, concentric five jacks can only be set in the middle and upper part of antitheft door and Liang Ge region, middle and lower part, the dead bolt in concentric five jacks is driven to be inserted or pulled out by the universe rod of main lock, compare other common antitheft door, can significantly improve equally and tamper-proof, anti-pry open performance, but the rectangle installing hole that middle part is opened after all is larger in size, door leaf integral rigidity there is impact, main lock preventing destructing performance is also simply because of the many one layer of steel plate i.e. longitudinal plates in its fixed installation position, and fastness strengthens to some extent。

Especially, when main lock is arranged on the middle part of door leaf side, it is unfavorable for improving anti-the prying open of antitheft door, preventing destructing performance: because this kind of situation majority is lock core type of drive, lock point quantity is many, resistance is big, the range that dead bolt, locking bolt move is smaller, and the dead bolt length namely inserting doorframe jack is comparatively short, is unfavorable for improving the pick-proof performance of antitheft door。Specify by latest national standards, first, the second of anti-theft safety door, third, four grades of fourth, locking between corresponding doorframe and door leaf count should respectively no less than 12,10,8,6, so locking mechanism comprises multiple lock point and belongs to custom requirements, therefore, lock core type of drive is difficult to the requirement that meets Multiple locking point long dead bolt of arranging in pairs or groups。

Especially, when lockset installation site is not on door leaf side, and it is placed in door leaf, then be conducive to improving anti-the prying open of antitheft door, preventing destructing performance: because handle type of drive (also including driven by power mode) that adopt in such cases, dead bolt range or insert the dead bolt greatest length of doorframe jack and can improve more than 1 times more。Wherein, drive the drive mechanism that dead bolt runs, be suitable for adopting the transducer being critical piece with rotating disk。Concrete measure is: rotates handle and drives driving member to move or rotate, and then drive the dead bolt of door leaf middle side edge to move, also drive the middle rotating disk being positioned in the middle part of door leaf to rotate simultaneously, middle rotating disk drives the vertically moveable of universe rod again, universe rod drives top rotating disk, bottom rotating disk to rotate again, finally drives middle and upper part, the dead bolt of middle and lower part does the movement of horizontal direction。Wherein, only need to increase the radius of middle rotating disk, top rotating disk, bottom rotating disk, dead bolt stroke can be significantly increased。In this scenario, key, lock core are used for driving a stop component, then are controlled to drive the operation of certain driving member of dead bolt by this stop component, and suffered by key, lock core, resistance is all less。This scheme relates to two aspect problems, and one is the anti-technical opening performance of lockset, anti-lock instrument destructive characteristics；Two is handle anti-damage performance。Both performances are not up to standard, and only dead bolt length increases 1 times, can not guarantee that antitheft door is safe。A kind of fixed cross mechanical anti-theft lock (ZL201410020215.X) of lock core, is characterized in: cannot technical opening；Anti-skid plate in lock body can destroy lock core by anti-lock instrument；Anti-drilling sheet outside lockhole can anti-electric drill damage lock core；Handle and limiter of moment assembling, handle can dally；Handle drives and unblanks, and namely handle can drive the whole dead bolt of door body to run, and can realize long dead bolt, big stroke。Therefore, this theftproof lock is installed in double-inserting type antitheft door, as one of scheme, it is possible to solve the problems that antitheft door exists。

Further, the entablature of doorframe and the sill of the upper side of door leaf or doorframe and and the bottom side of door leaf between correspondence position also be provided with the slotting ear of same structure, double; two plate, concentric five jacks and corresponding dead bolt or locking bolt, in order to upper and lower, orientation, three, side locking anti-theft door simultaneously。
