Between be equipped with driving member, resetting spring and movable axis are disposed between thumb wheel and knob；One end of the resetting spring
Portion is inconsistent with driving member, and the other end of the resetting spring and the one end of movable axis are inconsistent；The movable axis it is another
One end is threaded through on knob；Limit spring and locating part are equipped with movable axis, is equipped with and locating part in the madial wall of lock housing
Matched limiting slot；During promoting movable axis to move forward compression reseting spring, when locating part and limiting slot align
When, the one end of the locating part can be placed in limiting slot under limit spring effect.
The utility model is further set：Rotary knob rod is equipped with knob, the rotary knob rod is equipped with for installation activity axis
Movable span and the limit hole worn for locating part, the movable span are connected with limit hole.
The utility model is further set：Be additionally provided with retaining spring and positioning ball in lock housing, the rotary knob rod it is outer
Side wall be equipped with the matched positioning groove of positioning ball, rotary knob rod is in rotary course, when positioning ball and positioning groove phase
During alignment, a part for the positioning ball can be placed in positioning groove under retaining spring effect.
The utility model beneficial effect：When on the knob in door, promoting movable axis to move forward, in promotion activity axial direction
During the dynamic compression reseting spring of reach, when locating part is aligned with limiting slot, the one end of the locating part can be spacing
Limiting slot is placed under spring effect so that movable axis can not be moved rearwards, and back locking function is opened, at this time during key insertion fuse,
Since locating part limitation movable axis is moved rearwards and is locked, cause key can not be inserted into position, key tooth flower can not be matched and passed
Moving part cannot be introduced into thumb wheel, and key can not open lock core, is using original key can not also open lock core outdoors, is improving lock core certainly
The anti-theft performance of body, it is easy to operate, securely and reliably.
When knob drives rotary knob rod rotation, position-limited marble can be pressed by limiting slot so that position-limited marble is gradually pressed into
In rotary knob rod, after locating part is pressed into rotary knob rod, movable axis is moved rearwards under return spring active force, and key can open lock
Core.

Embodiment
1 to Fig. 4 a kind of anti-theft lock core structure of the utility model is described in further details referring to the drawings.
A kind of anti-theft lock core structure, including lock housing 1, are provided with fuse 2, thumb wheel 3 and knob 4, wherein thumb wheel in lock housing 1
3 are rotatably arranged in lock housing 1, and driving member 5 is equipped between fuse 2 and thumb wheel 3, and key promotes driving member 5 to be placed in through fuse 2
In thumb wheel 3, key is rotated at this time, by rotating member thumb wheel 3 can be driven to rotate.
Resetting spring 6 and movable axis 7 are disposed between thumb wheel 3 and knob 4；The one end of the resetting spring 6
Inconsistent with driving member 5, the other end of the resetting spring 6 and the one end of movable axis 7 are inconsistent；The movable axis 7
The other end is threaded through on knob 4；Limit spring 8 and locating part 9 are equipped with movable axis 7, lock housing 1 madial wall be equipped with
The matched limiting slot 11 of locating part 9；Promote movable axis 7 move forward compression reseting spring 6 during, when locating part 9 with
