Description

Horizontal internal lock strains at the two-way locking security door of formula multiple spot

The utility model relates to a kind of employing and strains at the spin of the two-way lock-in techniques of formula multiple spot and touch type and strain at the knocker technology; the door leaf resistance of failure is improved more than 20 times, and make the robber can't destroy and open the novel anti-theft door of door lock with the comprehensive door lock of mechano-electronic, horizontal internal lock, lock body duplicate protection technology.

Society goes up the robber and destroys security door at present, the life that takes place frequently of burglary, the event frequency of doing violence, subject matter has two, the one, the security door insufficient strength, the 2nd, door lock is easily destroyed, the countermeasure of each security door producer also mainly contains 2: the one, and strengthen thickening security door steel size, and improve manufacturing process, the 2nd, improve the door lock technology and change multi-point fastening into.Even but like this, the intensity increase rate is little, the intrinsic weakness of various door locks still can not solve, and security door is improved at all.Certain Provincial Technical Supervision Bureau carries out rupture test in December, 98 to 19 batches of security doors from various parts of the country, various security doors are all destroyed in 14 minutes, the fastest only 45 seconds, great majority are in minutes promptly destroyed, security door can not be antitheft, influence citizen and live in peace, the market an urgent demand puts into the melting pot existing security door.

The purpose of this utility model is the problem that thoroughly solves above-mentioned two aspects, providing a kind of need not increase the steel size and the door leaf resistance of failure is improved more than 20 times, total survivability reaches 5～10 tons, and overcome the intrinsic shortcoming of various door locks, guarantee that the robber can't open door lock with special unlocking tool according to peacetime training, also can't use electric drill, bullet, saw, file, cutter, hammer, ripping bar to destroy the novel anti-theft door of door lock.

The purpose of this utility model is achieved in that as shown in Figure 1, adopt two-way lock-in techniques of formula and the automatic knocker technology that strains at of rotating of touch type of straining at 4 jiaos of security doors and middle part, 4 limits, promptly use vertical keeper (4) simultaneously at same keyed end or two adjacent keyed ends, the laterally two-way locking of keeper (3), thus all Tensioning buckle is dead in 4 directions with door leaf and doorframe.The automatic rotation of touch type at each middle part, limit of door leaf strains at knocker (15) and can guarantee that door leaf reinforcing angle and knocker are on the same straight line fully, improve the condition that it bears tension stress.When door leaf is prized and impact, because of door leaf 4 limit straight line Tensioning buckles dead, leave one no latitude, thereby as long as doorframe is not crooked, then the door leaf top to bottom, left and right, front and rear all can not occur bending and deformation, door leaf is destroyed by flexural deformation and changes into the stretch-draw rupture failure, resistance of failure improves more than 20 times, break a thick 3-4mm, the required destructive power of the reinforcing angle of length of side 40-50mm is 5～10 tons, this is that the manpower instrument is definitely inaccessible, and it has fundamentally solved the problem of security door insufficient strength.

In the middle part of opening middle part, limit and upper and lower side, door leaf adopt the touch type spin to strain at the knocker technology, as shown in Figure 2, it is by the knocker plate with holes (31) of rotatable 90 degree, the control gate buckle rotates touches spherical surface body (32), knocker sheet reset spring (33), bearing support (34), knocker plate rotating shaft (35), spring pull bar (36) is formed.The spherical surface body that effectively plays a role is 1/8 spherical surface body of a what aperture of door plate next door, side.Strength when closing by door leaf, the door leaf edge collision also promotes the spherical surface body rotation, make the knocker plate turn 90 degrees and enter door leaf and open in the square hole of flank side surface square hole or door leaf upper and lower end face thereupon revolving automatically, overlap with the door leaf reinforcing angle, knocker hole and angle steel hole are overlapping, the keeper (17) that links closely inserts in this two hole, and door leaf and doorframe Tensioning buckle is dead.Extract keeper when opening the door out, after spherical surface body was left in the door leaf inside edge, back-moving spring pulling knocker board reversal 90 degree may go in the doorframe again, thereby door leaf can continue outwards to open.The with holes fixed knocker (16) that strains at of door leaf hinge edge is directly entering in the door leaf lateral aperture at closing time, overlap with reinforcing angle, two holes are overlapping, and are locked with the keeper that links closely (17), thus guarantee door leaf the right and left and up and down two ends straight line Tensioning buckle extremely on doorframe.

At the reinforcing angle place of door leaf key, as adopt the anti-saw of elasticity baffle technology at reinforcing angle place, door leaf lower end, as shown in Figure 4, it is by baffle plate (21), chute (22), alignment pin (23), back side spring (25), lower springs (26), lower springs backing plate (27) is formed.Since baffle plate when stressed about, porpoise, can't exert oneself to it, saw blade also is easy to fracture, thereby can prevent that the robber from stretching into the sawed-off reinforcing angle of saw blade after punchinging near the angle steel, the assurance reinforcing angle can only be broken by 5～10 tons of pulling force, guarantees the resistance of failure that door leaf is high.

Each keyed end is by the open and close action of push and pull system (5) by rotating disk (6) each keeper of centralized Control.When electromagnetic force or artificial rotary turnplate, the motion of push and pull system and each keyed end keeper and correlation as shown in Figure 5, each interlinking lever end point of the digitized representation among the figure in the small circle, on behalf of the each point displacement, arrow move direction.

Ought be 3. → 2. among Fig. 5: Then the middle part Tensioning buckle is dead on a left side.Promptly as long as pull rotating disk clockwise, then about the door leaf, about vertical, the horizontal two-way locking, stuck simultaneously of each keyed end; If counter rotation, then each keyed end will be opened simultaneously.

For preventing the robber after punchinging on the door leaf, hand or instrument are stretched in the hole, cut off connecting rod (5), or catch connecting rod (5) oppositely firmly, promote the rotating disk counter-rotating, thereby make the reverse interlock of all connecting rods, open each keeper.This patent is gone up the orientation that changes connecting rod (5) with angle shape rod at rotating disk (6), make about it, about place in line and just in time under corresponding door leaf reinforcing angle (24) protection, thereby be difficult for being cut off by the robber.Simultaneously the clamp (12) on the rotating disk (6) is stuck on the alignment pin, thereby the robber can't make the reverse interlock of each connecting rod.

This security door is taked whole angle steel reinforcement means, runs through the air cock integral reinforcing by whole vertical, horizontal angle steel, and angle steel two ends Tensioning buckle is dead.For keeper (3), (4) of inserting doorframe along the angle steel direction, then constitute a rigid unitary by keeper sliding sleeve (46) and reinforcing angle, further improve rigidity.

Existing various multi-point fastening security door all is to rely on tiny key rotation to drive rotating disk (6) and whole push and pull system, whole keeper system, thereby the strength deficiency, has limited the size and the stroke of keeper; This security door is with Electromagnetic Drive or manually, thereby keeper can be unrestricted, can do thicker firmly, stroke is longer, can pass doorframe as required, directly insert three face wall body and floors, it is fixed to form straight bolt type lock, destructive power major part that doorframe bears is directly absorbed by body of wall and floor and bear, thereby need not increase the steel size doorframe is thoroughly strengthened.

The door lock of this patent adopts the comprehensive door lock technology of mechano-electronic, by horizontal internal lock electronic lock and mechanical lock is combined together.Be that this security door is installed electronic lock and mechanical lock simultaneously, as shown in Figure 1, both remove has electronic signal reception, identifier, control chip respectively, outside the key function of electromagnetic actuator device and mechanical lock, both shared same control rotating disks (6), same push and pull system (5) and same keeper system (3,4,17), under the normal condition electronic lock receive and the identification electronic signal after, self-closing Electromagnetic Control circuit drives rotating disk (6) rotation with electromagnetic force, opens each keeper.The electronic signal number is many, and repeatability is minimum, and confidentiality and safety are fine, and be easy to operate.In case occur having a power failure, or electronic original part damages and other electronic failures, then available key is opened the horizontal internal lock (10) that pins safety box (7), manpower rotates rotating disk and opens each keeper, thereby has solved power failure, the embarrassment that electronic failure causes, remedied the weakness of electronic lock poor reliability, because this mechanical lock is horizontal interior dress, the robber can't be destroyed or open, thereby kept the safe characteristics of electronic lock simultaneously.

Electronic lock can adopt magnetic card lock or Fingerprint Lock, and electromagnetic actuator device of its chip (41) and rotating disk (42,43) and back-moving spring (44) are installed in the protection box (7), and signal receiver (18) is installed in the door leaf front.The electronic signal of one 8 figure place sign indicating number, repetitive rate are 1/100000000th, can think and can not repeat, and confidentiality and safety are fine, and the robber is not knowing can't to open door lock under the situation of password, if then safer with fingerprint signal, and easy to operate.Even the robber has destroyed signal receiver, still can not connect the circuit of electromagnetic actuator device, still can not open door lock.The electronic lock poor reliability, helpless shortcoming is solved by horizontal internal lock when meeting power failure or electronic failure.

As shown in Figure 3; the rotating disk (6) and the rotating disk handle (29) of the open and close of control keeper; locator card (12) alignment pin (13) all places the protection box (7) with channel-section steel is formed or steel plate is made; the protection lid pins with horizontal internal lock; horizontal internal lock lock body also places the protection box, and with the steel pipe duplicate protection of cutting half open.Internal lock is installed in indoor direction, and lockhole is parallel with the shop front, over against the cavity (28) of protection lid.This technology both can solve the embarrassment outside the door that owner is refused when power failure or electronic failure occurring, made the robber can't open or destroy door lock again.Because the robber does not have key, cannot see door lock again, be with wrist revolution 270 degree in narrow cavity, the backhand reverse operating may not opened door lock with any general unlocking tool; Instruments such as electric drill, bullet, cutter, hammer, saw, file, pincers, ripping bar all can't and be exerted oneself near internal lock simultaneously; Even electric drill and bullet can pass the steel plate of protection box, also can skid at the curved surfaces of second protection steel pipe, wander off or fracture; Because lockhole is parallel with the shop front, electric drill or bullet also can't directly be aimed at lockhole and inject or pierce.Therefore present technique has remedied electronic lock and has run into power failure, electronic component damage and during electronic failure owner can't enter and also can't keep in repair outdoors, the shortcoming of poor reliability has kept electronic lock confidentiality and safe advantage again.

Because this patent has adopted a series of unique design and technology, as: 1. strain at the two-way lock-in techniques of formula multiple spot; 2. touch type rotates the knocker technology that strains at automatically; 3. elasticity is prevented the saw baffle technology; 4. push and pull system prevents cutting, preventing reverse linkage technique; 5. door leaf and body of wall, the straight bolt type lock in floor are decided technology; 6. the comprehensive door lock technology of mechano-electronic; 7. lock technology in horizontal; 8. control system and internal lock lock body duplicate protection technology etc., thereby this security door has following advantage:

1. need not increase door leaf steel size and thickness and just improve resistance of failure more than 20 times: strain at the two-way lock-in techniques of formula multiple spot and rotate the knocker technology that strains at automatically because this security door has adopted, make vertical, the horizontal two-way locking simultaneously of 4 jiaos of door leafs and 4 limits middle part, with the integral reinforcing angle steel with about door leaf and the doorframe, left and right sides straight line Tensioning buckle is dead, reinforcing angle can only be ruptured by stretch-draw and not have the possible of distortion, and door leaf top to bottom, left and right, front and rear all directions can not occur bending and deformation.When the robber prizes or clash into door leaf, the door leaf stress condition changes fully, change into the stretch-draw rupture failure by flexural deformation destruction, thereby under the condition that does not increase security door steel size and thickness, improve the intensity of security door more than 20 times, employing thickness is the reinforcing angle of 3～4mm, hem width 40～50mm, and the total anti-destructive power of door leaf reaches more than 5～10 tons.Adopt the anti-saw of elasticity baffle technology simultaneously, make the robber can't stretch into the sawed-off reinforcing angle of saw blade after punchinging on the door leaf, guarantee that reinforcing angle neither is bent, also not by sawed-off, and can only break with 5-10 ton force amount, this is that the manpower instrument definitely can't be broken.Its anti-theft capability even surpass a lot of safe doors, society's cabinet of insuring is happened occasionally by the sled incident, but the robber really can't destroy this security door.

2. the robber can't rely on peacetime training to open door lock with any general unlocking tool: this security door adopts the comprehensive door lock technology of mechano-electronic; lock technology and internal lock lock body duplicate protection technology in horizontal; electronic lock and mechanical lock are combined together dexterously; constitute a kind of new door lock system; the signal that it has electronic lock respectively receives and recognition device; electromagnetic actuator device; the key function of mechanical lock; but have common door lock control rotating disk and protective device thereof; common push and pull system and common keeper system; thereby kept the advantage of two kinds of door locks, overcome their shortcoming and defect separately.Its digital repetitive rate of the electronic lock of one 8 figure place sign indicating number has only 1/100000000th, can think and can not repeat that confidentiality and safety are fine.The robber can know to open door lock under the situation of password, if then safer with fingerprint signal.And horizontal internal lock is mounted in indoor direction; lockhole is parallel with the shop front; side facing to protection lid cavity; the robber is not having key, under the invisible again situation, in narrow cavity; wrist revolution 270 degree; the backhand reverse operating may not rely on peacetime training to open door lock with general unlocking tool, and promptly two kinds of door lock robbers can't open all the time.

3. instruments such as electric drill, bullet, saw, file, pincers, cutter, hammer, ripping bar all can't destroy door lock: because the keeper controlling organization drive unit of this security door electronic lock and horizontal internal lock and internal lock lock body all are installed in the protection box that channel-section steel or steel plate make, the internal lock lock body is also with the steel pipe duplicate protection of cutting half open.The protection lid is installed in indoor direction.Therefore electric drill, cutter, hammer, saw, file, pincers, ripping bar all can't near and destroy internal lock; Drill bit and bullet promptly enable to pass from the outside protection box steel plate, also can skid at the curved surfaces of second protection steel pipe, wander off or fracture; Because internal lock is horizontal, lockhole is parallel with the shop front, and drill bit and bullet also can't directly be aimed at lockhole and inject or pierce; Even the robber has destroyed the signal receiver of electronic lock, also can't open the protection box, can't connect the rotating blade drive circuit and open keeper; Again owing to adopted push and pull system to prevent cutting, preventing reverse linkage technique, even the robber after punchinging on the door leaf, also is difficult to cut off the keeper connecting rod; Cut off the also harmless door leaf safety of a connecting rod; The robber stretches into hand or instrument and catches connecting rod also can't make the reverse interlock of all connecting rods in the hole, and other keepers still make security door safe and sound.

4. this door-locking system has overcome power failure, the embarrassment that electronic failure causes, the reliability height, easy to operate: electronic lock has secret, safety, easy to operate advantage, in case its disadvantage is to have a power failure, electronic component damages or other electronic failures, electromagnetic actuator device is just inoperative, outside the door that owner will be refused, also electronic failure can't repaired outdoors, at this moment native system can be opened horizontal internal lock with key, manually rotation control rotating disk is opened in the security door inlet chamber and maintenance failure, has solved owner and can not enter and go home, the also difficult situation that can't keep in repair overcomes the shortcoming of sub-electronic lock poor reliability.

5. door leaf hinge, dead bolt, doorframe are thoroughly strengthened: because about this security door door leaf, about 4 sides all multiple spot strain, buckle extremely on doorframe, it has shared most of destructive power that common security door hinge, dead bolt bear, it is thoroughly strengthened, even hinge, dead bolt are destroyed, door leaf still 4 directions by two-way locking, button extremely on doorframe, still safe and sound.Again because this patent does not rely on the rotation of tiny key to drive control rotating disk and whole push and pull system, whole keeper system as common multi-point fastening security door fully, but the dependence electromagnetic force drives or manpower is manual, therefore, keeper can do firmer solid, stroke is longer, and can pass doorframe as required and directly insert three face wall body and floors.Adopt this straight bolt type lock to decide method, the destructive power that doorframe is born reduces significantly, need not increase the steel size doorframe is thoroughly strengthened.Because each position of this security door all greatly strengthened, thereby this patent has also greatly alleviated the harm that cause in slit that common security door produces inevitably in manufacturing, transportation, installation process.Below in conjunction with drawings and Examples the utility model is further specified:
