Description
Technical field
The present invention relates to a kind of lock core, especially relate to and a kind of anti-drillingly turn cylinder lock set.
Background technology
The performance major embodiment of mechanical anti-theft lock is both ways: one is anti-technical opening performance, and two is opposing destructive characteristicss.The performance of these two aspects must meet the requirement of user simultaneously, and Neither of the two can be dispensed, otherwise is not just theftproof lock truly, will there is potential safety hazard.
Simple dependence chooses quality material, increase part dimension thus strengthen scheme that lockset anti-destructive opens ability obviously science, rationally not, because also need to consider the factor such as processing technology, processing cost, abrasion resistance, corrosion resistance of main parts size especially lock core.The lock core of some lockset is easy to be destroyed by the tool that goes into operation by force, and reason has many-side:
One is material aspect, and good lock core copper is done, and the machining accuracy of lockhole, marble hole, difficulty of processing and abrasion resistance, corrosion resistance can reach gratifying degree, but limited mechanical strength.The mechanical strength of aluminum alloy lock core is then lower.As with alloy, then cost is high, and is difficult to processing, not corrosion-resistant;
Two is stressed aspects, the lock core of core-inset type pellet, blade mechanism lock is in the hypodynamic weak tendency state of opposing all the time, the diameter of lock core is generally 12mm, resistance arm is less, during powerful torsion lock core, lock core, pellet are subject to shearing force larger, marble hole edge easily occurs that retrospective is out of shape, and overall lock core is easy to be destroyed, and even cannot withstand a single blow;
Three is lack safeguard measure, and it is external that lock core is directly exposed to door, directly with the tool close contact that goes into operation by force, wrecks unavoidable.
The lockset being provided with lock cylinder is a kind of lock comparatively popular in the market, the structure of this lockset forms by lock body, lock core, pellet and pellet return spring are equipped usually, its preventing techniques of the lockset of this structure is unblanked and the poor-performing of destructive picking lock, and most of pellet is single or double setting, therefore along with the increase of lockset sales volume, the mutual opening rate of this lock also increases thereupon, and safety decreases.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the above-mentioned defect that prior art exists, provide a kind of strictly can control the high anti-technical unlocking of mutual opening rate, safety turn cylinder lock set.
The technical solution adopted for the present invention to solve the technical problems is, a kind of anti-technical unlocking turn cylinder lock set, comprise lock core, lock tube and key, the key suitable with key is provided with in described lock core, the periphery of described lock core is provided with anti-drilling sheet and suitable step bullet and the bullet that replaces with key, described lock tube comprises lock core pipe and crossbeam, the centre of described lock core pipe is provided with a word direct dialing wheel, one end of a described word direct dialing wheel is provided with jump ring, the two ends of described crossbeam are provided with anti-drilling draw point, the both ends of described crossbeam are provided with and suitablely with lock core turn pellet assembly, the described pellet assembly that turns comprises the envelope pearl be provided with from top to bottom, marble spring, upper pellet and lower pellet, the described tartar being provided with employing 3D engraving technology on the key, step bullet on described tartar and lock core and the bullet that replaces suitable.
Further, described tartar comprises tartar groove and tartar point, described tartar groove is the curve tartar groove that 3-8 (preferably 5) tartar basic point is formed, and the distance of described tartar basic point and key side is 1.7-2.4mm, and the horizontal range of adjacent two tartar basic points is 0.7mm; The width of described tartar groove is 1.4mm, and the degree of depth of described tartar basic point is 0.6mm, 1.2mm or 1.8mm, reduces mutual opening rate, stops the antitheft ability of joining.
Further, the quantity of described tartar point is 3-8 (preferably 5), and the diameter of described tartar point is random, tell tartar point the degree of depth be 0.6mm or 0.2mm, reduce mutual opening rate and avoid key to insert in lock core, during rotation, key can be pulled out the situation generation of a part.
Further, the invariant position of described tartar point.
Further, the quantity of described anti-drilling draw point preferably 4, is evenly located at the two ends of crossbeam, and described anti-drilling draw point is transversely arranged.
Compared with prior art, structure of the present invention is simple, low cost of manufacture; Can stop electric drill and carry out technical unlocking to the destruction of lock body and tinfoil, striker and single hook etc., the two ends of lock tube crossbeam are provided with anti-drilling draw point, strengthen lock body; Safety is high, long service life; Three D tartar engraving technologies, mutual opening rate is low, antitheftly joins.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
The Structure of cross section schematic diagram that Fig. 2 is lock core shown in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
See figures.1.and.2, the present embodiment comprises lock core 2 and lock tube 4, is provided with the key suitable with key 1 in lock core 2; The periphery of lock core 2 is provided with anti-drilling sheet 3 and suitable step bullet 11 and the bullet 10 that replaces with key 1, lock tube 4 comprises lock core pipe 4-1 and crossbeam 4-2, the centre of lock core pipe 4-1 is provided with a word direct dialing wheel 15, one end of one word direct dialing wheel 15 is provided with jump ring 14, play fixation, prevent lock core to be pulled out; The two ends of crossbeam 4-2 are provided with anti-drilling draw point 5, the both ends of crossbeam 4-2 are provided with and suitablely with lock core 2 turn pellet assembly, turn pellet assembly comprise from top to bottom be provided with envelope pearl 9, marble spring 8, upper pellet 7 and lower pellet 6, key 1 is provided with the tartar adopting 3D engraving technology, the step bullet 11 on tartar and lock core 2 and the bullet 10 that replaces suitable.
