Description
One, technical field
The utility model relates to a kind of lock bridge numeration lock, particularly is applicable to the numeration lockset that customs's container is used, and belongs to technical field of lockset structures.
Two, background technology
At present, customs's container is with the general identifying code of fixing identification code when unblanking or breaking seal that adopts in traditional sealing lock, case envelope, the lead sealing of lock, and this method safety is not high, and the as easy as rolling off a log fraud of doing is decoded and stolen, and operation and maintenance is got up all cumbersome.
Three, summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design is provided, and functional safety is reliable, has preventing decryption, anti-cheating, anti-theft feature, and is easy to use, the numeration lockset with numeration function.
The utility model is achieved through the following technical solutions:
A kind of lock bridge numeration lock, special character is the tapered end that has lock core shifting block 13 3 that its inside is provided with outside visible digital wheel 7 and is inserted key by the outside, lock core shifting block 13 places in the set groove of lock dog only 12, be provided with two lock beam holes that can hold lock bridge 2 in the housing 1, lock bridge 2 one ends are fixed in housing 1 inside, and the other end then cooperates locking with lock beam hole; Only lock dog 12 can stretch in the lock beam hole and with the lock bridge 2 on housing 1 top and cooperate, lock bridge 2 with end position that lock dog 12 cooperates and be provided with and can hold the notch that ends lock dog 12, end stretch under lock dog 12 ends lock dog spring 16 at its rear portion the effect lock beam hole and with the notch clamping of lock bridge 2, be provided with the ratchet driving lever 5 of band transcoding ratchet 9 in the lock beam hole, ratchet driving lever 5 tops lean lock bridge 2, the bottom is pressed and is established driving lever return spring 10, housing 1 also is provided with the combination driving wheel that transcoding ratchet 4 and transcoding gear 8 be made of coaxial with digital wheel 7, transcoding ratchet 9 meshes with transcoding ratchet 4 transmissions of combination driving wheel, the transcoding gear 8 of combination driving wheel and driven gear 11 engaged transmission on top, driven gear 11 simultaneously also with the gears engaged of digital wheel 7, also be provided with the retaining ratchet 6 that cooperates with transcoding ratchet 4 that is used to prevent digital wheel 7 rollbacks on the wheel shaft of driven gear 11;
The number of described digital wheel 7 can be set with the need, its last digital wheel place is provided with the termination plate 14 of band termination plate axle 15, by the 15 control digital wheels of the termination plate axle on the termination plate 14, when digital wheel 7 turns to greatest measure, it can not be rotated by 15 controls of termination plate axle.
This locks operating principle: when this lock normally uses, inserted in the lock beam hole of housings 1 by lock bridge 2, promote ratchet driving lever 5 and drive transcoding ratchet 9, transcoding ratchet 9 is stirred number of transcoding ratchet 4 commentaries on classics.When lock bridge 2 inserted certain degree of depth, the notch of lock bridge 2 was ended lock dog 12 and is only being pinned under 16 effects of lock dog spring.When pressing down lock bridge 2, must insert key and just can be pressed into lock bridge.
Open and locking: the normal unlatching, key inserts tapered end 3 rotational lock core shifting blocks 13, and drive ends lock dog 12 and unblanks.This moment, ratchet driving lever 5 ejected lock bridge 2 under 10 effects of driving lever spring return spring.
Locking inserts key earlier, presses down lock bridge 2 and inserts housing 1 promotion ratchet driving lever 5 drive transcoding ratchets 9, and transcoding ratchet 9 is stirred transcoding ratchet 4 changes a number.When lock bridge 2 inserted certain degree of depth, the notch of lock bridge 2 was ended lock dog 12 and is only being pinned under 16 effects of lock dog spring.
When lock bridge 2 every insertions once, digital wheel 7 change one digit numbers.It is unique one group of number.When number changes to maximum, just can not become again, rotate because there is termination plate axle 15 to block digital wheel 7 on the termination plate 14.So can not reuse when combination padlock is used maximum.
A kind of lock bridge of the utility model numeration lock, reasonable in design, functional safety is reliable, has numeration function and preventing decryption, prevents practising fraud, antitheft function, and is easy to use.
