The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1~Fig. 4 is the structural representation of the utility model lock embodiment 1, this lock includes the lock housing 1 that the orthodox car mechanical lock all has, lock core 2 and the key 15 that is complementary, in the lock core 2 of automotive lock keyhole is arranged, be provided with the pellet shot from a slingshot hole that pellet shot from a slingshot 6 is installed in lock core 2 and the lock housing 1, lock core 2 also has the pilot hole that compression spring 8 is installed, compression spring 8 keeps contacting with pellet shot from a slingshot 6, there is the spacer pin 7 that locks in the concave ring groove 18 that can insert lock core 2 inner end of lock housing 1, there is a bit of position one side to have groove 3 on the lock core 2, steady pin 5 is installed in the groove 3, be set with torsionspring 4 on the steady pin 5, this section lock core is positioned on the position of groove 3 opposite sides and has chute 11, movable jube 9 is installed in the chute 11, movable jube 9 has plush copper 12 near an end of lock housing 1, a sliding bevel 10 is arranged at plush copper 12 bottoms, and the other end of movable jube 9 has two to stretch into also the top pin 17 of roof pressure torsionspring 4 and two spacer blocks 14 up and down in the groove 3; Have hole 13 on the lock housing 1, the plush copper 12 of movable jube 9 is a blocking when slipping into hole 13, as shown in Figure 1; The plush copper 12 of movable jube 9 is a unlocking condition when skidding off hole 13, and as shown in Figure 2, two spacer blocks 14 up and down of movable jube 9 all inserted in the corresponding on the key through hole that has and blocked key channel this moment; Concave ring groove 18 1 sides at lock core 2 are provided with the straight trough 19 that communicates with concave ring groove 18, and when locking, spacer pin 7 places straight trough 19, and when unblanking, lock core 2 pushes inward when proceeding to extreme position, and spacer pin 7 just is in the concave ring groove 18, and this moment, just rotatable lock core was unblanked.
In order further to strengthen anti-theft effect, can respectively be provided with a projection 16 that can stretch on the recessed flank of tooth of key in the side that two top pin 17 of movable jube 9 are close to key; A plurality of movable jubes can also be set with the increase unlocking difficulty, and the installation site of movable jube also can be top or middle part at lock core.
The contacted end of described movable jube and lock housing also can be made as faces end directly, this moment corresponding lock housing the Kong Zewei ramp bore so that movable jube slips in the hole of lock housing; Movable jube can be formed by a plurality of spacer block stack combinations, also can be that a plurality of spacer blocks are connected as a single entity.
When unblanking, key 15 is inserted in the keyhole, at this moment, key 15 just will connect the pellet shot from a slingshot 6 of lock core 2 and lock housing 1 and push aside, make that non-marble is connected between lock core and the lock housing, with key 15 lock core 2 is pushed inward then, the plush copper 12 of movable jube 9 just is forced out the hole 13 of lock housing 1 in this process, also move inwards simultaneously with lock core, this moment, two top pin 17 of movable jube 9 just pressed torsionspring 4, and two spacer blocks 14 also stretch in corresponding two through holes up and down of key simultaneously up and down, and key again can be finished and unblank at last.
During locking, key is gone back to initial position, this moment, spacer pin 7 moved to the entrance of straight trough 19, and then key outwards moved and drive lock core move outward, movable jube is also outer simultaneously moves, because sliding bevel 10 is arranged at its plush copper bottom, when movable jube is moved outside and under the effect of torsionspring 4, slip in the hole 13 of lock housing 1, key moves past outward that torsionspring is unclamped gradually in the journey, initial position when making movable jube return blocking, and the spacer block of movable jube also breaks away from the through hole of key, and just can transfer to key this moment, finishes block action.
Fig. 5~Fig. 9 is the structural representation of the utility model theftproof lock embodiment 2, movable jube 9 on this anti-theft lock core is substantially the same manner as Example 1, the spring of activity jube of just bearing down on one changes cartridge type spring 21 into and is installed in the counterbore 22 of movable jube 9 sides, and cartridge type spring 21 contacts with the spur 23 of movable jube side; Also have additional three spacer blocks 14 that are spaced from each other setting simultaneously, the side of spacer block 14 has the counterbore 22 of mounting spring 21, and spring 21 contacts with the spur 23 of spacer block 14; Lock housing 1 is equipped with ramp bore 20 with the corresponding position of each spacer block, can skid off when making spacer block at unlocking condition under the interaction of ramp bore 20 and spring 21 when ramp bore 20 is blocked key channel and inserted in the through hole of key, at blocking can slip in the ramp bore 20 of lock housing.It unblanks identical with embodiment 1 with the lock operation step.
Theftproof lock of the present utility model also can only be provided with a spacer block and be connected with spacer block on lock core spring, and on lock housing, offer corresponding hole, just can realize purpose of the present invention.
Because the spacer block on the lock core must block key channel when unblanking, therefore form a slit, space with narrow and small complications, just can clamp down on effectively illegal unlocking tool to pellet shot from a slingshot action unblank, thereby strengthened the theftproof performance of lock.
The utility model lock also can be used for the mechanical lock of other difformity pellet shot from a slingshot.
