Description
Technical field
The present invention relates to the technical field of lockset, particularly relate to a kind of fork-shaped thin slice top locking lock core.
Background technology
In the prior art, have various locksets, like electric lockset; The fingerprint lockset; Modal lockset or mechanical lockset, it mainly is to be made up of lock core and tapered end and the pellet shot from a slingshot and the spring that are installed in the tapered end inner orbit, can rotate each other between lock core and the tapered end; Reaching the purpose of unblanking, and pellet shot from a slingshot each other and spring combine the key of unblanking with key.The mechanical type cylinder lock set of above-mentioned routine easily through stirring or technical method such as vibration reaches the effect of unblanking, thereby causes the safety of these locksets relatively poor, is unfavorable for antitheft.
Summary of the invention
To the objective of the invention is in order addressing the above problem, locking lock core in a kind of fork-shaped thin slice top to be provided.
Technical scheme of the present invention is: a kind of fork-shaped thin slice top locking lock core; Contain overcoat, cylindrical core body; The inside of overcoat is cylindrical hole; Described core body coupling is installed in overcoat inside, and described core body is provided with the axial cylindrical keyhole, and the thin slice that is provided with the direction coupling of some on the described core body is at least installed the slit; The outside of the shape of cross section of the core body that this thin slice installation position, slit is corresponding is that the middle part of circular arc, inner edge is that circular arc, the dual-side that keyhole forms is parallel straight flange; Each thin slice is installed the fork-shaped thin slice that the thickness coupling all is installed in the slit; The top of this fork-shaped thin slice is crossbeam; Both sides place above-mentioned thin slice to install on the inner edge of the corresponding core body in position, slit for perpendicular leg, the crossbeam on top, and this crossbeam passes through with described keyhole is cross-section mutually; And being absorbed in the certain degree of depth of keyhole, the perpendicular leg of both sides is clipped in above-mentioned thin slice and installs outside the dual-side of the corresponding core body in position, slit; The top of described crossbeam is provided with ejector pin, and the top of this ejector pin is provided with spring and pellet shot from a slingshot, and this spring and pellet shot from a slingshot are positioned at the spring eye of sleeve side wall, and the end of spring is provided with end socket; The outer face of described core body is provided with the rotation breach.
The top of described crossbeam is provided with depression, packs in this depression in described ejector pin lower end.
The ejector pin on described crossbeam and top thereof is an integral structure.
The thin slice of described some is installed in the slit, and it is reverse having the direction in a thin slice installation slit and the direction in other thin slice installation slit at least.
The thin slice of described some is installed the slit and is layout in the same way.
The core body of described pellet shot from a slingshot installation site is provided with columniform pellet shot from a slingshot pilot hole; The diameter of this pilot hole is installed the thickness in slit greater than described thin slice; Spring eye diameter in this pilot hole diameter and the described sleeve side wall is identical, and this pilot hole connects with described thin slice installation slit.
The lower end of described two perpendicular legs and the top of crossbeam are the circular arc with overcoat inner cylinder face coupling.
The degree of depth that the crossbeam of described each fork-shaped thin slice is absorbed in the keyhole is different.
The degree of depth that has at least the crossbeam of a fork-shaped thin slice to fall in the keyhole in the fork-shaped thin slice of described some skips over the half the of keyhole diameter.
Beneficial effect of the present invention
The lock core of this invention adopts a plurality of fork-shaped thin slices, and its crossbeam passes through with keyhole is cross-section mutually, thereby forms each on & off switch of unblanking of this lock core; And the outer edge of the perpendicular leg of fork-shaped thin slice be provided with core body on the breach of prolate groove coupling, the half-twist key supports the crossbeam of fork-shaped thin slice in key inserts keyhole, with the pellet shot from a slingshot jack-up on the fork-shaped thin slice outside core body; This moment, screw key and drive core body rotation was realized unblanking, and half-twist is extracted key out again; Because thin slice is upper and lower mobile and reset under the effect of its stage clip and pellet shot from a slingshot; Thereby realize the locking of lock core, because the crossbeam of each fork-shaped thin slice has only a position and prolate groove to mate after being supported by key; It is lockset position of coupler; Too high or too lowly can not realize that all the breach of fork-shaped thin slice is corresponding with the prolate groove, and then can not realize unblanking, thereby stop the possibility of technology unlocking basically.
It is reverse having the direction in a thin slice installation slit and the direction in other thin slice installation slit in the thin slice installation slit of described some at least; So just can make that to be installed in its inner fork-shaped thin slice installation direction opposite; The crossbeam of fork-shaped thin slice in the opposite direction forms the structure of shut the gate; Can be with the axial sealing of keyhole, the structure that utensil can not be opened this shut the gate basically of unblanking of other except key need in the process of unblanking also just to have determined respectively to different direction jack-up fork-shaped thin slices; Thereby further increased the difficulty of unblanking, improved the performance that prevents technology unlocking.
