Description

The adjustable type mechanical code lock

The utility model belongs to lock class, particularly a kind of adjustable type mechanical code lock.

Known mechanical code lock all is to realize unblanking or shutting by the bayonet socket on the interior wheel and jump ring or bayonet lock contraposition and dislocation, the dynamics difference of big when stirring password, feel to the bayonet socket sound, easily from finding sound and the feel discerning bayonet socket contraposition whether secret mark and stir password to judge that lock is to open or close in appearance, therefore, lose the confidentiality and the anti-theft feature of lock fully.

The purpose of this utility model, be to provide on a kind of structure and pellet shot from a slingshot be set in the wheel in adopting, removable pin is arranged, can be in same position at interior wheel, pellet shot from a slingshot and the expansion link axle that dead bolt the fuses shape that becomes to unblank, dislocation between interior wheel, pellet shot from a slingshot and dead bolt do not fuse the bar axle for shutting, and can not find any recognition code secret mark in appearance, can not judge that lock is the adjustable type mechanical code lock that opens or closes from the sound and the feel of transfer password.

The purpose of this utility model is achieved in that

Describe in detail below in conjunction with drawings and Examples,

Fig. 1 is the utility model A-A structure cut-away view,

Fig. 2 is the foreign steamer structural representation of Fig. 1,

Fig. 3 is the interior wheel construction schematic diagram of Fig. 1,

Among the above-mentioned figure: 1. lock ring, 2. main shaft spring, 3. foreign steamer, 4. interior wheel, 5. removable pin, 6. main shaft spacer pin, 7. main shaft, 8. pellet shot from a slingshot retainer spring, 9. location pellet shot from a slingshot, 10. pellet shot from a slingshot, 11. foreign steamers location pellet shot from a slingshot, 12. lock bodies, 13. lock cylinder, 14. dead bolts, 15. lock ring springs, 16. lock ring alignment pin, 17. the lock ring screens, 18. main shaft spacer pin stopper slots, 19. movable cotter way positions, 20. foreign steamer removable pin screens, 21. the pellet shot from a slingshot screens of foreign steamer location, 22. foreign steamer outer peripheral face digit order numbers, 23. interior wheel spindle holes, 24. interior wheel pellet shot from a slingshot hole, the movable pin-and-hole of 25. interior wheels.

Its structure as shown in Figure 1, this mechanical code lock is made up of lock ring 1, lock body 12, lock core, wherein: lock core comprises foreign steamer 3, interior wheel 4, main shaft 7, pellet shot from a slingshot 10, dead bolt 14, the foreign steamer side face that is provided with removable pin screens 20, these screens 20 correspondences at foreign steamer 3 medial surfaces has ten digit order numbers 22 of 0～9, with digit order number 22 pellet shot from a slingshot screens 21 (see figure 2)s in foreign steamer location is arranged equidistantly, makes the foreign steamer location with foreign steamer location pellet shot from a slingshot 11; Be provided with spindle hole 23, pellet shot from a slingshot hole 24, movable pin-and-hole 25 (see figure 3)s at interior wheel 4, the pellet shot from a slingshot hole 24 of interior wheel 4 is provided with pellet shot from a slingshot 10, movable pin-and-hole 25 is put removable pin 5, the equal in length of the thickness of foreign steamer 3, interior wheel 4 and pellet shot from a slingshot 10, design like this, during transfer foreign steamer password, can be connected as a single entity the pellet shot from a slingshot 10 of interior wheel and dead bolt 14, location pellet shot from a slingshot 9, under 8 effects of pellet shot from a slingshot retainer spring, become a telescopic bar axle, the state that the lock place leaves; The pellet shot from a slingshot dislocation of wheel in if transfer foreign steamer password makes, pellet shot from a slingshot and dead bolt, be not integral the bar axle, dead bolt 14 is no room to swing a cat, makes the state of pass, lock place; Main shaft 7 is provided with lock ring screens 17, main shaft spacer pin stopper slot 18, movable cotter way position 19, there is main shaft spring 2 inner end of main shaft in lock body 12, wheel 4 spindle holes 23 were placed in the foreign steamer 3 again in main shaft 7 penetrated, foreign steamer 3 sticks foreign steamer removable pin screens 20 rotations with interior wheel 4 by removable pin 5 and forms cipher code set one by one, main shaft spacer pin 6 is stuck on the main shaft spacer pin stopper slot 18, limit main shaft move left and right; Lock ring 1 long end interlocks with dead bolt 14, make lock ring can not break away from lock body 12 with main shaft alignment pin 16, there is lock ring spring 15 on the lock ring top, lock ring can be ejected when unblanking automatically, lock ring 1 short end is stuck in the lock ring screens 17, shoot sub-lock core 13 in dead bolt 14 stage casings, just can become the coded lock that double insurance is arranged.

The password figure place is how much, increases and decreases the cipher code set number as required, as: two passwords are two cipher code set, and five passwords then are five cipher code set, and the cipher code set number is many more, and confidentiality is strong more, and the utility model only shows four cipher code set.

1. embodiment unblanks referring to Fig. 1: when all transferring foreign steamer 3 each cipher code set to password, the pellet shot from a slingshot 10 of interior wheel 4 and dead bolt 14, location pellet shot from a slingshot 9 are connected as a single entity into a telescopic bar axle, rotate lock cylinder 13 with key, make dead bolt 14 break away from lock rings 1 and unblank; 2. shut: as long as transfer foreign steamer cipher code set, pellet shot from a slingshot 10 dislocation of interior wheel 4, pellet shot from a slingshot 10 is not integral the bar axle with dead bolt 14, and each cipher code set just can not move left and right, and dead bolt 14 no room to swing a cat ins do not break away from so interlock with lock ring 1, lock the state that is in the pass; 3. change password: under the situation of unblanking, make the weak point of lock ring 1 hold the lock ring screens 17 of leaving main shaft, shift main shaft 7 onto certain position for 12 li toward lock body, the movable cotter way position 19 that the removable pin 5 in the interior wheel 4 is just fallen main shaft, interior wheel 4 breaks away from foreign steamer 3, stir foreign steamer this moment, transfer required code number, remove out the thrust to main shaft, main shaft resets under 2 effects of main shaft spring, removable pin 5 pop into position, interior wheel 4 reset with foreign steamer 3 and just get a new cipher code set.

The utlity model has simple in structure, strong security, easy to use flexible, can not drive lock because of transferring random password, be difficult for destroyed, performance is safe and reliable, and the password figure place can arbitrarily increase and decrease, and the many more confidentiality of figure place are high more, the equipped lock cylinder of going up has more the double insurance function, do not have complexity, peculiar part, need not special installation, produce in batches easily.
