The specific embodiment:The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～7, lock body is made of box body 5 cylindraceous, the enclosing cover 3 that is fixed on box mouth place, the inner cap 11 that is fixed on this box body back side; Inwall at box body 5 has some chutes 6 that distribute along generatrix direction, is provided with the quantity button 1 identical with this chute on the surface of enclosing cover 3.Be located in lock body lock core by intert on enclosing cover 3 with the outer knob 2 of through hole 15, empty set first password dish 4 and the second combination disk 21 on this outer knob, be located at guide pillar 22 between above-mentioned two combination disk, be enclosed within the first back-moving spring 25 on this guide pillar, bend to the pellet frame 24 of concave character type structure in being embedded in each chute 6, be fixed on pellet 23 on each pellet frame by screw thread, pass the baffle plate 20 that through hole 15 is fixed on by screw on the second combination disk 21 and consist of, the position distribution corresponding to each pellet 23 on first password dish 4 and the second combination disk 21 has marble hole 7.Dead bolt 10 is located in enclosing cover 3, toggle mechanism by the axle sleeve 9 that is fixedly connected with dead bolt 10, the bearing pin 8 that passes this axle sleeve, be hinged on this bearing pin left end and be provided with straight runner 26 the first shifting block 12, be hinged on this bearing pin right-hand member and be provided with straight runner 26 the second shifting block 13, pass the straight runner 26 of the first shifting block 12 and be fixed on finger 14 on the second combination disk 21, be located at pulling sleeve 19 on inner cap 11, pass this pulling sleeve and consist of by the inner button 16 that feather key 18 is attached thereto, be fixed with another finger 14 that stretches in the second shifting block 13 straight runners 26 on pulling sleeve 19; Position on the surface of enclosing cover 3 corresponding to each pellet frame 24 is provided with button 1.
For easy to use, be equipped with the second back-moving spring 17 on dead bolt 10, inner button 16 and guide pillar 22.
Operating principle:
Before use, the user is first according to selected certain several pellets 23 conduct " password pellet " of the needs of oneself, regulate each " password pellet " position on pellet frame 24, can insert the marble hole 7 of first password dish 4 when moving it to left position and be in " lock-out state " (see figure 5), can not insert the marble hole 7 of the second combination disk 21 when moving to right position and be in " neutral position state " (see figure 6); Regulate all the other each pellets 23, move it to left when position and can not insert the marble hole 7 of first password dish 4 and be in " neutral position state " (see figure 6), can insert the marble hole 7 of the second combination disk 21 when moving to right position and be in " locking state " (see figure 7).
When entering, only need press respectively each button 1 corresponding with " password pellet ", corresponding pellet frame 24 can move right, until encounter the left side of the second combination disk 21.At this moment, the left end of " password pellet " is deviate from from the marble hole 7 of first password dish 4, is in " neutral position state "; And all the other each pellets 23 still are in " neutral position state ".Rotate outer knob 2 the second combination disk 21 is rotated, the finger 14 that is fixed on this second combination disk can drive dead bolt 10 retractions by the first shifting block 12, and door lock is opened immediately.After entering, only need pushing inner button 16, baffle plate 20 can promote each pellet frame 24 by the second combination disk 21 and be moved to the left, each " password pellet " and each pellet 23 reset (namely respectively in the marble hole 7 of " password pellet " insertion first password dish 4 correspondences and again be in " lock-out state ", each pellet 23 is in " neutral position state ").
When going out, rotate inner button 16, pulling sleeve 19 drives the second shifting block 13 by finger fixed thereon 14 and moves downward, dead bolt 10 retractions, and door lock is opened immediately.After going out, two kinds of chains modes are arranged: (1) locks formula, pellet 23 can be placed in " locking state " and realize the door lock locking as long as press arbitrarily one or more buttons corresponding with being in " neutral position state " pellet 23; (2) homing position type, if with outer knob 2 to pulling outward, each " password pellet " can be placed in " lock-out state " and realize door lock locking.
If pushed the wrong password when opening the door or mess code has appearred in pellet 23, only need outer knob 2 is pulled out and can be moved to the left by baffle plate 20 drive the second combination disk 21, each pellet frame 24 also is moved to the left under the effect of this second combination disk, each " password pellet " and each pellet 23 be reset to original setting (namely respectively " password pellet " and be in " lock-out state ", each pellet 23 is in " neutral position state "), re-enter again password at this moment and can unblank.
When illegally unblanking, when pellet frame 24 moved right to the left side of the second combination disk 21, the right-hand member of each pellet 23 inserted immediately the marble hole 7 of the second combination disk 21 and is in " locking state ", thereby realized locking, antitheft.
If password is given away secrets, only need again selected certain some pellet 23 as " password pellet ", regulate each " password pellet " position on pellet frame 24 and can realize re-encrypted.
