Embodiment
Fig. 1 to Fig. 3, key provided by the utility model, including key body 2 are seen, positive and negative the two of the key body 2
Face Central Symmetry is provided with rows of primary and secondary hole of bead groove, the movable hole of bead for penetrating key body on the fluted shaft line of the primary and secondary hole of bead
204th, 205 it is, equal positioned at primary and secondary hole of bead groove and the movable hole of bead 204, the serpentine path groove 203 of 205 sides, each primary and secondary hole of bead groove
Including the coaxial depth sub- hole of bead groove 201 different with diameter and female hole of bead groove 202, the movable hole of bead 204,205 is located at key sheet
The front end of body 2, the mobile beads component 206,207 that can be moved up and down, the movable hole of bead are respectively equipped with the movable hole of bead 204,205
204th, be respectively equipped with flange collar 2041,2051 in 205, mobile beads component 206,207 respectively by identical mobile beads 2062,2072 and
The riveting composition of activity bead sleeve 2063,2073, mobile beads 2062,2072 are provided with groove between activity bead sleeve 2063,2073 respectively
2061st, 2071, mobile beads component 206,207 passes through the flange collar in groove 2061,2071 and the movable hole of bead 204,205 respectively
2041st, 2051 it is engaged.
During unlocking, referring to Fig. 4, key is inserted in the keyhole 15 of lock core 3, each primary and secondary hole of bead in the front of key body 2
Groove and mobile beads component 207 are corresponding with about one group primary and secondary pearl in tapered end 1 in lock housing 4 and lock core 3 respectively, of key body 2
Female hole of bead groove 202 and sub- hole of bead groove 201 on female hole of bead groove respectively with lower female pearl 5 in the lower primary and secondary pearl in lock core 3 and
Lower sub- pearl 6 coordinates, and so as to promote down female pearl 5 and lower sub- pearl 6 to move up and down, lock housing 4 is promoted again with pearl 5 female at present and lower sub- pearl 6
Upper female pearl 7 and upper sub- pearl 8 in interior corresponding upper primary and secondary pearl are moved, due to being provided with lock core 3 below keyhole 15
Thrust pearl 10 corresponding with mobile beads component 207, now, in the presence of thrust pearl spring 9, thrust pearl 10 promotes mobile beads group
Pearl sub- up and down 8,6 in part 207 and upper and lower primary and secondary pearl moves upwards so that upper female pearl 7 and lower mother in all primary and secondary pearls up and down
Pearl 5, upper sub- pearl 8 and lower sub- pearl 6 are rearranged to 3 rotary position of lock core, when horizontal grid 12 move back from the horizontal grid groove 14 of lock housing 4
When being back to lock core 3, lock core 3 can be rotated and realize unlocking.
It is each sub up and down in lock housing 4 and lock core 3 in the presence of return spring 16 after extracting key referring to Fig. 5 during locking
Upper female pearl 7 in female pearl returns to the state of initial mutual dislocation with lower female pearl 5, upper sub- pearl 8 with lower sub- pearl 6 so that the quilt of lock core 3
It is spacing to rotate, while horizontal grid 13 are stuck in further that lock core 3 is stuck between lock housing 4 and lock core 3, realize locking.
Because mobile beads component 207 is located in the front end of key body 2 so that chosen using technical instrument, push aside and open
Difficulty further increase because first to choose unlock first 1 before the pearl of primary and secondary up and down in female pearl and sub- pearl choose again behind with work
Sub- pearl corresponding to dynamic pearl component 207 up and down in primary and secondary pearl needs more instruments, because hoodle above blocks, space by
To limitation, it is difficult to operate, it is also difficult to position, therefore be difficult skilled unlocking, the master worker of special key does not copy on the market yet
The utility model key.
In order to preferably increase unlocking difficulty, set if being additionally provided with key body 2 for dry side pearl 11 in the lock core 3 of tapered end 1
Serpentine path groove 203.Referring to Fig. 5 during locking, side pearl 11 be provided with the groove that the horizontal side of grid 13 is engaged in lock core 3, respectively
Groove on side pearl 11 staggers when key is extracted, and horizontal grid 13 fall in the groove less than side pearl 11（In the effect of spring 12
Lower horizontal grid 13 exit from the groove of side pearl 11）, its opposite side is stuck between horizontal the grid groove 14 and lock core 3 of lock housing 4, and lock core 3 is by card
Unlocking can not firmly be rotated.Referring to Fig. 4 during unlocking, key is inserted, the serpentine path groove 203 on key body 2 drives the weight of side pearl 11
New arrangement so that the groove arrangement on each side pearl 11 in line, rotates lock core 3, overcomes the effect of spring 12 so that horizontal grid 13
Side stretch on side pearl 11 in the groove being arranged in a straight line, the opposite side of horizontal grid 12 is then retracted into from the horizontal grid groove 14 of lock housing 4
Lock core 3, realize and unlock.This serpentine path groove and this horizontal grid structure are more difficult to choose, push aside and open, and also more against shock rifle is unlocked.
Due to primary and secondary hole of bead groove, mobile beads component 207（206）It is that Central Symmetry is located at key sheet with serpentine path groove 203
The tow sides of body 2, be just provided with Dual Action pearl modular construction key on such key body 2, the function of achievable two-sided unlocking.
