Description

High-strength double safety cipher lock

The utility model relates to the coded lock that a kind of coded lock, particularly safety cabinet are used.

The coded lock that existing safety cabinet is used has mechanical type and electronic type two big classes.It is not high enough that mechanical type exists mechanical strength, the strong inadequately drawback of security personnel's performance.

The purpose of the utility model is to provide the mechanical code lock of a kind of high strength, dual fail-safe.

The method that the utility model adopts mechanical code lock and cylinder lock to organically combine realizes above-mentioned purpose.

High strength dual fail-safe coded lock by tapered end, be fixed on power transmission shaft on the tapered end, be enclosed within the lock of power transmission shaft and tapered end outside, plain film and the lug that is contained in tapered end and power transmission shaft outside formed.Cylinder lock is housed in the tapered end, and tapered end is equipped with locking closure outward, has the through hole and the groove that match with the pellet shot from a slingshot dead bolt on tapered end and the lock.

Below in conjunction with embodiment shown in the drawings, the utility model is explained in detail.

Accompanying drawing is the utility model front view.Among the figure: 1. retaining nut, 2. power transmission shaft, 3. pin, 4. lug, 5. plain film, 6. packing ring, 7. screw, 8. spring, 9. lock, 10. pellet shot from a slingshot dead bolt, 11. grooves, 12. through holes, 13. tapered ends, 14. cylinder locks, 15. locking closures.

High strength dual fail-safe coded lock has a tapered end 13, and 100 scales are arranged on its taper seat.Cylinder lock 14 is contained in the tapered end 13, and locking closure 15 is contained in the outside of tapered end 13.The outer rim of the front portion of tapered end 13 and locking closure 15 has straight burr.The power transmission shaft 2 of T font is screwed on tapered end 13 and (does not draw in the accompanying drawing), simultaneously cylinder lock 14 is fixed between tapered end 13 and the power transmission shaft 2.The rear portion of tapered end 13 has the through hole 12 that matches with pellet shot from a slingshot dead bolt 10.

On the lock 9 screw hole is arranged, lock 9 is enclosed within the outside of power transmission shaft 2 and tapered end 13, has the groove 11 that matches with pellet shot from a slingshot dead bolt 10 on the inwall.Spring 8, some plain films 5, a slice lugs 4 are contained in the outside of lock 9 and power transmission shaft 2 successively, and pin 3 is sold lug 4 and power transmission shaft 2 together.Screw 7 is arranged on the sheet, packing ring 6 is arranged between sheet.The interior shoulder of packing ring 6 is prominent to be contained in the groove of power transmission shaft 2.Retaining nut 1 is arranged at the top of power transmission shaft 2.

When high strength dual fail-safe coded lock is installed, earlier lock 9 is screwed on safe door, assembly with power transmission shaft 2, cylinder lock 14, tapered end 13 and locking closure 15 is contained in the lock 9 again, at last spring 8, plain film 5, lug 4, packing ring 6 are contained in the outside of lock 9 and power transmission shaft 2, plug pin 3, tighten retaining nut 1.

When high strength dual fail-safe coded lock uses, at first take off locking closure 15, with key cylinder lock 14 is opened, rotational lock head 13 then, to good password, lock opened.If cylinder lock 14 is not opened, pellet shot from a slingshot dead bolt 10 passes the through hole 12 of tapered end 13 and the groove 11 of lock 9, and tapered end 13 and lock 9 are fixed together, and just can't can't unblank to password.

Because the utility model has been done structural innovation and improvement on the basis of original mechanical code lock, has strengthened mechanical strength, thereby use the instruments such as pliers, hammer this lock can't be opened. Have simultaneously the dual insurance of spring lock and coded lock, improved reliability. Also have the advantage easy to operate, that profile is attractive in appearance, can be widely used in safety cabinet, national treasury door, gun cabinet and other secret occasions.

Embodiment shown in the drawings is DQ100-A type high-strength double safety cipher lock, and 2 flat sheets are arranged, and the length of lock is 89, the maximum external diameter φ 70 of lock.

Claims (1)

1, a kind of high strength dual fail-safe coded lock, by tapered end (13), be fixed on power transmission shaft (2) on the tapered end (13), be enclosed within the lock (9) of power transmission shaft (2) and tapered end (13) outside, plain film (5) and the lug (4) that is contained in outside tapered end (13) and the power transmission shaft (2) formed, it is characterized in that being equipped with in the tapered end (13) cylinder lock (14), tapered end (13) is outer to be equipped with locking closure (15), has the through hole (12) and the groove (11) that match with pellet shot from a slingshot dead bolt (10) on tapered end (13) and the lock (9).
