The specific embodiment
As shown in the figure, the utility model comprises left lock core body 1 and the right lock core body 2 being connected by connecting rod 3, left lock core body 1, the interior relative left lock core shaft 4 of pegging graft respectively of right lock core body 2, right lock core shaft 5, the thumb wheel 6 of unblanking is set between left lock core body 1 and right lock core body 2, one side of connecting rod 3 has downward extension and forms fixed block 7, fixed block 7 can be arranged on left lock core shaft 4 and unblank between thumb wheel 6, also can be arranged on right lock core shaft 5 and unblank between thumb wheel 6, determine according to specific needs, or left or right is the selection of direction, and non-limiting protection domain, unblank between thumb wheel 6 He Zuo lock core shafts 4 by Left Drive piece 8 connection for transmissions through fixed block 7, unblank between thumb wheel 6 He You lock core shafts 5 by right drive block 9 connection for transmissions, the concrete structure of above-mentioned connection for transmission can be that the side at Left Drive piece 8 and right drive block 9 forms that thumb wheel is protruding connects 19, opposite side forms that lock core is protruding connects 20, lock core is protruding connect 20 sides axially slidably sleeve in Zhong Bingyou lock core shaft of lock core shaft, drive rotation, thumb wheel is protruding connect 19 sides axially slidably sleeve in the thumb wheel 6 of unblanking to drive thumb wheel 6 rotations of unblanking, in right lock core shaft 5, be provided with stage clip 10 and ejector pin 11, balancing plug 12 is set in fixed block 7, the axially eccentric setting slide lock rationed marketing 13 in thumb wheel 6 of unblanking, one end of slide lock rationed marketing 13 and ejector pin 11 offset, the other end matches with balancing plug 12, on the side face of slide lock rationed marketing 13, be symmetrical arranged two cannelures 14, unblank radially to offer up and down two lock grooves 15 in thumb wheel 6, in lock groove 15, assemble locking spring 16 and lock pin 17, and encapsulated by mounting 21, lock pin 17 matches with cannelure 14.The effect that lock pin 17 matches with cannelure 14 is that at the lock body of a side and balancing plug 12, to be subject to violence damage removed or while dropping, because lock pin 17 is by the locking of 14 pairs of slide lock rationed marketings 13 of cannelure, robber can not attempt to rotate by taking out slide lock rationed marketing 13 thumb wheel 6 of unblanking.Spacing block set 18 is set on the two side of fixed block 7, the purpose of design of spacing block set 18 be can be because of violence damage when lock core integral installation is on lock body not whole by jacking lock body in.As shown in Figure 3 when left lock core body 1 is during by violence damage, the stage clip 10 on the right loses support, by ejector pin 11, promoting slide lock rationed marketing 13 moves to the left, one end of slide lock rationed marketing 13 is backed down balancing plug 12 and is entered in fixed block 7, make to unblank thumb wheel 6 completes locking with fixed block 7, the thumb wheel 6 of unblanking can not rotate, and reaches the object that anti-violence is opened.When slide lock rationed marketing 13 moves into place, under the effect of locking spring 16, lock pin 17 enters the cannelure 14 of slide lock rationed marketing 13 in the both sides up and down of slide lock rationed marketing 13, slide lock rationed marketing 13 can not be moved again, under this state, robber can not attempt to rotate by taking out slide lock rationed marketing 13 thumb wheel 6 of unblanking, and has further strengthened theftproof performance.Above-described embodiment is described the preferred embodiment of a kind of improved lock core mechanism of the utility model; not the design of utility model and scope are limited; do not departing under the prerequisite of the utility model scheme; various external form modification and improvement that those skilled in the art make the technical solution of the utility model, all should fall into the protection domain of a kind of improved lock core mechanism of the utility model.
