The utility model has the advantages of high confidentiality and high safety, which is suitable for various safes, anti-theft doors and other safeguards.

Description

Cipher lock with key exchanging words

The utility model relates to a kind of improvement of coded lock.

Used coded lock is owing to having the word machine structure, so after having only the password of aligning, could open lock with key.Though this coded lock has certain anti-theft capability, because the word machine structure is fixed on the lock body, as long as other people rotate repeatedly to the word machine structure, finally may open this lock.

The utility model proposes a kind of new scheme, will change key-type into, will take off the word machine structure after coded lock locks and take away, overcome the drawback that other people can unblank to sign indicating number voluntarily the word machine structure.

This coded lock is by word key and lock body two parts are formed.To the front end of word key have the garden cylindricality to word key bar 1, longitudinally there is key bar groove 2 the bar front portion, there are scale 3 and knob 4 in the rear portion.Lock body comprises cylinder lock and cryptographic system two parts.Cylinder lock partly has pellet shot from a slingshot locking bolt 17, pin tumbler lock body 18, spring locks keyhole 19 and dead bolt 20.Cryptographic system is by to word keyhole 5, guard aperture plate 6, form word slice 10, partition 13, axle 14, locating shaft 15, stop screw 9 and password screw 16.One garden cylindrical cavity is arranged in the axle 14, its slightly larger in diameter is in the diameter to word key bar 1, and axle 14 is equipped with stop screw 9 near on the wall to word keyhole 5 front ends, and its outstanding inner chamber part can just be blocked key bar groove 2, when guaranteeing the word key turns, axle 14 can be rotated together.When unblanking, will insert word keyhole 5 the word key, stop screw 9 is stuck in the key bar groove 2.Hold knob 4, order aligns the breach to word slice 10 with scale 3 clockwise or repeatedly rotate certain scale counterclockwise mutually in accordance with regulations, the twisting marble lock key, and the breach that pellet shot from a slingshot locking bolt 17 inserts word slice 10, dead bolt 20 withdrawals, lock i.e. unlatching.During locking, the twisting marble lock key stretches out dead bolt 20, and pellet shot from a slingshot locking bolt 17 is to withdrawing from word slice 10 breach, and twisting knob 4 one is arbitrarily angled, again will be to the word key from getting final product extracting the word keyhole 5.Knowing under the prerequisite of password, marble lock key must be arranged simultaneously and can open lock the word key.Guard aperture plate 6 is being equipped with in word keyhole 5 outsides, and its effect is to extract behind the word key, seals word keyhole 5, prevents that foreign matter from entering in the hole.

The utility model is simple in structure, strong security, safe and reliable, is suitable for various safety cabinet, security door and other security systems.

Fig. 1 is the utility model schematic side view.

Fig. 2 is the utility model front schematic view.

Shown in accompanying drawing 1-2.

To 40 millimeters of word key bar 1 length, 5 millimeters of diameters, 30 millimeters of scale 3 diameters, number of division is 60, and knob 4 diameters are 10 millimeters, are 3 to word slice 10, and stop screw 9 is M2 * 5.Lock body is conventional combination lock repacking on the market, is contained in after the repacking on the pocket wall type safety cabinet.During installation, earlier fastening arm-tie is fixed on the safety cabinet both sides, on wall, digs out corresponding installation hole then, safety cabinet panel and metope are made even, floating with concrete, can use after doing.For making safety cabinet better hidden, can hang up overcovers such as calligraphy and painting, wall calendar in the safety cabinet outside.
