A key hole of the lock core is in a closed type structure, and therefore, an unlocking tool cannot enter into the key hole to ensure that the lock core has higher safety.
Description
Technical field
The present invention relates to a kind of closed type mechanical lock core and key thereof.
Background technology
At present, though known mechanical lock and key body thereof are different, unlatching is many in same cross section, and snap is also distributed on parallel lines, is easily put in keyhole and implements technical opening by instrument, makes lock core lose theftproof.
Summary of the invention
It is directly exposed in lockhole that the object of the invention is to overcome existing machinery lock core unlatching tooth, is easily implemented the deficiency of technical unlocking.The invention provides a kind of closed type mechanical lock core and key thereof, in its lock core keyhole, all the time in closed state, common technology unlocking tool cannot be got involved, and can effectively prevent technical and be turned round picking lock core by violent tool and unblank.
The technical solution adopted for the present invention to solve the technical problems is: circular lock core comprises shell, interior pressing spring, interior pressure pellet, locking key, rotary locking cylinder, circle wheel and cylindrical key.It is characterized in that: lock core shell bullet groove is equipped with interior pressing spring, pellet and acts on locking key; Two locking keys are placed in shell lock keyway and rotary locking cylinder lock keyway simultaneously, locking key is connected as a single entity both, the fixing rotary locking cylinder of shell can not rotate, rotary locking cylinder circle wheel groove is equipped with the circle wheel of interior pore area projection, circle wheel outer has circle wheel lock keyway and arc groove, two locking keys are placed in rotary locking cylinder lock keyway and circle wheel lock keyway simultaneously, and locking key is connected as a single entity both, and rotary locking cylinder is free to rotate; Key has the one group of groove matching with circle wheel endoporus projection, key with protruding is inserted to rotary locking cylinder end socket endoporus pit by casing cover endoporus grinding undercut, rotating 360 degrees, locking key is placed in circle wheel lock keyway and rotary locking cylinder lock keyway, now projection is on the key inserted to rotary locking cylinder end socket endoporus grinding undercut, stir rotary locking cylinder (tail end connects the plectrum of unblanking) and rotate, drive plectrum to unblank.
The present invention's advantage is compared to the prior art: the one, and in lock core keyhole, be enclosed type construction, common skilled unlocking instrument cannot be got involved.The 2nd, due to eight circle wheels being housed in rotary locking cylinder circle race, and each circle wheel outer is provided with two circle wheel lock keyway and ten arc grooves that groove depth is different, make the combination of eight circle wheel lock keyway positional alignment have hundred million kinds of variation patterns, in situation not directly perceived, by stirring the projection of circle wheel endoporus, be difficult to find accurately the position that lock keyway is corresponding with locking key, technical opening rate is very low.The 3rd, lock core shell lid steel material, makes through Technology for Heating Processing, has high-intensity Prying-resistant and drilling-resistant performance.The 4th, steel circle wheel shape anti-drill pad is rotatable in rotary locking cylinder, strengthens its anti-drilling performance.
