Description

Permutation lock using key to open or close

The utility model is that the improvement of existing lockset is invented, and relates to reinforcing door, safety door industrial and residential houses security door or common door repacking, and the new-type lockset that use at positions such as all kinds of safety cabinets is with the coded lock of unlatching of key check mark and locking.

Be installed in the one-way cipher lock on the safety cabinet at present and be installed in marble mechanical lock on all kinds of doors,,, adopted by people widely so be extended to today owing to have the unlatching and the locking function of its uniqueness.But these two kinds of locks also exist certain shortcoming and problem separately.The pellet shot from a slingshot mechanical door lock can be unblanked with master key, does not resist to pound, do not resist and bore, and is easy to destroyed.The one-way cipher lock also has the possibility of being split with normally unblank rule and sensation to password.Therefore these two kinds of locks are installed in also to be mounted on the door and all have certain insecurity on the safety cabinet.Single use is the safety that is difficult to guarantee the institute installation position.

The purpose that the utility model is implemented is for positions such as all kinds of security doors, safety door, safety cabinet provide a kind of new-type lockset of being made up of pellet shot from a slingshot machinery door lock core and one-way cipher lock, with key operated and coded lock locking.

The purpose of this utility model is achieved in that pellet shot from a slingshot machinery door lock core that existing tradition is used and one-way cipher lock couple together with parts such as lining dish, connecting box, screws and has formed a new-type lockset.Below in conjunction with accompanying drawing chief component of the present utility model and part are specifically described:

Accompanying drawing 1 is overall pattern of the present utility model.This Figure illustrates chief component of the present utility model and part.It is made up of three parts:

First is pellet shot from a slingshot machinery door lock core.It is made up of key 1, lock core 2, hold-down screw 3, lock core shaft 5, plectrum 6, driver blade 7 etc.

Second portion is mechanical code lock.It is formed by adjusting screw 9, collar 10,11, power transmission shaft 12, cottor pin 13, swiveling wheel 14, driven pulley 15,16, transmission nail 17,18, spring 19, lining dish 20, dial 24 etc.

Third part is the coupling part.It is made up of lock core fixed head 4, hold-down screw 21,22, connecting box 23 etc.

Accompanying drawing 2 is the A-A sectional view of accompanying drawing 1, has described plectrum 6 and has driven the rotation that each sheet of coded lock is taken turns.

Accompanying drawing 3 is axonometric projection graph of the present utility model, has described the position and the combined situation of face shaping and part.

The lock core 2 usefulness hold-down screws 3 that are characterised in that of the present utility model are fixed on the lock core fixed head 4, lock core fixed head 4 is fixed on the lining dish 20 with hold-down screw 21 again, swiveling wheel 14 usefulness cottor pins 13 are fixed on the power transmission shaft 12, driven pulley 15,16 is fixed on again on the lining dish 20, the other end is connected with connecting box 23 with screw 22, and connecting box 23 is fixed on dial 24 in the lock core shaft 5.

The utility model is a kind of new-type lockset that is combined into by original two kinds of locksets, has kept original lockset unique separately unlatching and locking function.As single use key and single accessing to your password is to be difficult to open and locking, must be to be inserted in dial and the lock core with key, and note is accurate number just can reach and open and the purpose of locking.Therefore this lockset have a fashion style, open locking convenient, safe and reliable, anti-drilling, characteristics such as prevent pounding.

Be further described below in conjunction with 1,2 pairs of the utility model of accompanying drawing:

When opening and locking should lock the time, should at first use 24 pairs of good keyholes of key dial, key 1 is inserted in the lock core shaft 5, screw key 1 drive lock core shaft 5 and driver blade in front 7 thereof, plectrum 6 is rotation thereupon also.The boss 8 of stirring that plectrum 6 drives on the power transmission shaft rotates the power transmission shaft 12 of interlock.The swiveling wheel 14 that is contained on the power transmission shaft 12 also rotates thereupon.Swiveling wheel 14 drives driven pulley 15,16 and turns in the scope of required scale.Rotate in the opposite direction with key 1, swiveling wheel 14 drives driven pulleys 15 and rotates in the opposite direction, aligns with the breach of driven pulley 16, and the breach that is just changeing swiveling wheel 14 with key 1 aligns with the breach of driven pulley 15,16 again.The breach alignment of three wheels can reach the purpose of unblanking.Opposite to more than key 1 forward or reverse 2 circles, swiveling wheel 14 drives driven pulley 15,16, makes the breach dislocation can reach the purpose of locking.

When mounted, dial 24 is fixed in the lock core shaft 5, and lock core 2 usefulness hold-down screws 3 are fixed on the lock core fixed head 4, and is connected as a single entity with hold-down screw 21 and lining dish 20.Connecting box 23 is pushed down rotation scale 24, with being threaded on the lining dish 20.When being inserted in the lock core shaft 5 with key 1, dial 24 is that left rotation and right rotation is done at the center with lock core shaft 5, is the position display dish that numbering, record are unblanked, and can rotate at connecting box 23 internal freedoms.With hold-down screw 22 connecting box 23 is fixed on the lining dish 20 then.
