Description
Technical field
The utility model relates to a kind of mechanical lock master, particularly a kind of multiple types blade anti-theft lock core combined by three kinds of variety classes blade assemblies and the novel key derived from.
Background technology
Although existing all kinds of mechanical lock head profile is ever-changing, the internal construction of tapered end is substantially identical, primarily of parts compositions such as tapered end, lock core body, keys, is aided with pellet different in size and marble spring, common locking and the open function forming tapered end.During blocking, the lower pellet in marble hole is all lower than lock core body surface under the elastic force effect of marble spring, and upper pellet half enters in lock core, and second half stays in lock body, and now lock core can not rotate.When after insertion key, the different key bit of height extrudes lower pellet after overcoming the elastic force of marble spring on the key, the rising making lower pellet upwards make differing heights is moved, whole lower pellet afterbodys and lock core body surface is caused to maintain an equal level, and upper pellet is all discharged lock core body, lock core body freely can rotate relative to tapered end under key drives, and lock core just can be opened.When this type of lock core has just released market, due to pellet circumferentially and distribute more, lawless person does not also have special pirate of the open instrument for the moment, and theftproof performance is better; But after use in a few years, market has occurred the special pirate of the open instrument for this type of tapered end, As time goes on and constantly theftproof performance also declines.For this reason, people develop again blade anti-theft lock core, and the moving tooth coordinated with key due to blade is whole on the same face, although pick-proof effect increases, but still by the pirate of the open of lawless person institute, anti-theft security performance needs to be improved further.Therefore, many manufacturers and knowledgeable people have carried out R and D, but not yet have rational product to emerge so far.
Summary of the invention
In order to overcome the above-mentioned disadvantage that existing blade anti-theft lock core exists, the purpose of this utility model is by being optimized combination and structure improvement to said structure, providing a kind of mutual opening rate is low, antitheft performance is good multiple types blade anti-theft lock core and key.
The utility model solves the problems of the technologies described above adopted technical scheme, it comprises tapered end, lock core body, key, lock core body is arranged in lock body rotationally, lock core body is provided with key hole, it is the blade groove of cross distribution with key hole that described lock core body is provided with some, described blade groove is built with three kinds of different types of blade assemblies, and three kinds of blade assemblies can sort arbitrarily in blade groove; First blade assembly comprises the first blade, the leaf spring of two forward and reverse arrangements, an angle of the key hole of the first blade is provided with angle tooth, the top of the first blade is provided with blade notch, and bottom is provided with spring positioning seat, and leaf spring is arranged between the spring positioning seat of two first blades; Second blade assembly comprises the second blade, the leaf spring of two forward and reverse arrangements, middle tooth is provided with in the key hole of the second blade, the top of the second blade is provided with blade notch, and bottom is provided with spring positioning seat, and leaf spring is arranged between the spring positioning seat of two second blades; Three-blade assembly comprises Three-blade, the leaf spring of two forward and reverse arrangements, heel teeth is provided with in three-vaned key hole, three-vaned top is provided with blade notch, and bottom is provided with spring positioning seat, and leaf spring is arranged between two three-vaned spring positioning seats; Described lock core body and tapered end are provided with the locking piece notch parallel with key hole, and locking piece notch is provided with locking piece, and the bottom of locking piece coordinates with the blade notch on all blades.
Further scheme of the present utility model, the positive and negative of described key is provided with unblank angle teeth groove and the middle teeth groove of unblanking that matches with middle tooth that match with angle tooth, and the both sides of key are provided with the heel teeth groove of unblanking matched with heel teeth.
Further scheme of the present utility model, described lock core body is provided with shift fork of unblanking.
After adopting said structure, the utility model has the following advantages and effect: one is because described blade groove is built with three kinds of different types of blade assemblies, three kinds of blade assemblies can sort arbitrarily in blade groove, when unblanking, the angle teeth groove of unblanking of key positive and negative, unblank middle teeth groove and heel teeth groove of unblanking promote to both sides simultaneously three kinds of different types of blade assemblies outwards mobile just can completing unblank, further increase opening difficulty, thus substantially increase the theftproof performance of anti-technical opening.Two is because blade is provided with spring positioning seat, and leaf spring is arranged between the spring positioning seat of two blades, and leaf spring is installed more convenient, uses more reliable.Three is that the key hole closure designs of blade center, therefore processes more convenient, can greatly enhance productivity and planeness because key hole design is at lock core body center.Four is the angle teeth groove of unblanking of key positive and negative, unblank middle teeth groove and heel teeth groove of unblanking, and two-sidedly can insert in key hole, unblanks more convenient, derives new structure key for this reason, make key have obvious distinguishing characteristics.
