Abstract

The utility model relates to a mechanical coded lock which comprises an outer casing, a lock shaft, a code correcting ring, a teeth blocking ring and a positioning board. Sliding grooves corresponding to two groups of coded teeth of the lock shaft are arranged in the center of the outer casing with the angles being interlaced; A group of coded teeth and B group of coded teeth are arranged on the lock shaft; and the purpose of technical unlocking prevention is achieved through the designs of the different heights and transverse dislocation of the coded teeth and the traps arranged in a coded hole. The mechanical coded lock has the advantages that a coded ring can be rotated without a trace left under unlocking and locking conditions, the security is good, the use is convenient, the structure is simple, and the manufacturing cost is low, and the mechanical coded lock is applicable to the anti-theft devices for bicycles, motorcycles, electric motor cars, burglarproof doors and garages doors, etc.

Description

A kind of mechanical code lock

Technical field

The utility model relates to a kind of lockset by unlock password, especially refers to a kind of mechanical code lock by the mode release of rotation password circle.

Background technology

At present, known mechanical code lock has by of bonding and the coded lock by roller rotational password circle.Press the complex structure of of bonding coded lock, each key is by staying fingerprint trace later, and password exposes easily.The coded lock of rolling password circle type is when unlocking condition, and the password circle can not rotate, and therefore password is found by the people easily when unlocking condition, and lock is easily by technical unlocking.

Summary of the invention

In order to overcome the deficiency of existing machinery coded lock, the utility model provides a kind of simple structure, and is easy to use, and cost is low, a kind of mechanical code lock of technical unlocking difficulty.

The technical scheme that its technical problem that solves the utility model adopts is: coded lock comprises shell, lock shaft, changes the sign indicating number circle, keeps off gear ring, location-plate.Central authorities have and the corresponding chute of two groups of password teeth of lock shaft intersecting angle in the shell, make the lock shaft in the enclosure can move left and right.Lock shaft is provided with A group and B organizes two groups of password teeth, and every group of password tooth is made up of 4 or many password teeth, and every group of password number of teeth amount equates with password number of turns amount.Two groups of password tooth height differences, A group password tooth height is greater than B group password tooth height, and from the vertical section, certain distance staggers about A group password tooth and B group password tooth, and height is different, sees that from drawing in side sectional elevation A group and B group password tooth are crossed as 90 ° or other angle.Change sign indicating number circle inwall and establish ten five equilibrium internal tooths, outer wall is carved with ten five equilibriums, 0～9 numeral as password.Retaining gear ring outer wall also divides ten five equilibrium external tooths, and arbitrarily the anglec of rotation is inserted in and is changed in the sign indicating number circle, forms a password circle, and under the effect of gear, the two is integrated and makes circular motion.Retaining gear ring inwall is provided with a high perforation and a low perforation, two perforation size height are corresponding with two groups of password tooth sizes of A, the B height on the lock shaft, the angle that two perforations intersect also equates with A, two groups of password teeth of B intersecting angle on the lock shaft, makes lock shaft can pass every two interior perforations of retaining gear ring smoothly.Two perforation height (depth) differences are provided with one or many trap holes in every retaining gear ring in addition, and the trap hole size equates with high perforation.Intersecting angle difference on the retaining gear ring between every trap hole.Intersecting angle between intersecting angle, perforation and the trap hole between intersecting angle on the retaining gear ring between two perforations and the trap hole is different.Every intersecting angle that keeps off between each set in gear ring trap hole also has nothing in common with each other.When having only the staggered angle of the angle of intersecting when high perforation and low perforation and lock shaft A, B group password tooth to coincide, lock shaft just can pass the retaining gear ring.When unblanking or during blocking, the password circle can rotate arbitrarily, all password teeth are all hided in the lock body just, and this moment, every password circle can arbitrarily rotate, and became to unblanking or blocking.

Location-plate is established at the lock body two ends, and during the open and close lock, location-plate blocks the password tooth and plays the role of positioning.

The beneficial effects of the utility model are: low different by two groups of password tooth depths on the lock shaft, and about stagger, the password circle is established high perforation, low perforation and many settings such as trap hole, has blocked the road of technology unlocking.Password number of turns amount can be made as 4 or many password circle combinations, and the cipher code set resultant is big, the purpose that reach simple in structure, easy to use, technology unlocking is difficult.

The specific embodiment

Installation process: in Fig. 1, every changes and is inserted in retaining gear ring 2 in the sign indicating number circle 3, (setting password figure and position before being inserted in) is combined into a password circle 1, every password circle 1 is put into code hole 6 on the shell 5, lock shaft 11 from left to right passes every password circle 1 successively by shell 5, adjust two perforations 12 by its rolling when passing password circle 1,13 angle, make two perforations 12 in the retaining gear ring 2,13 aim at two groups of password teeth 8 on the

lock shaft

11,9, every is passed successively, respectively remember every each password figure of aiming at graduation mark 17, the just password combination of this lock when passing.Location-

plate

4,18 is loaded onto on last both sides, and every location-

plate

4,18 is fixed installation by screw hole 10 usefulness screws.

Use: in Fig. 8 unlocking condition, behind password circle 1 rotational alignment password scale line 17, lock shaft 11 moves right, moving a password tooth that back B group password tooth 9 the keeps right plate 18 that is positioned blocks, make lock shaft 11 can not be again toward moving right, each

password tooth

8,9 this moment all in lock body 5 (as Fig. 9) is just password circle 1 can freely rotate, make the password confusion, be blocking this moment.Equally, in Fig. 4, aim at password after, lock shaft 11 is moved to the left, the password tooth that A group password tooth 8 the keeps left plate 4 that is positioned blocks, and makes lock shaft 11 no longer toward moving left, each

password tooth

8,9 this moment lock body 5 in (as Fig. 8) again is a unlocking condition at this moment.

Change a yard process: pull down location-

plate

4 or 18, aim at password after, lock shaft 11 just can all be pulled out, and takes out password circle 1, after changing sign indicating number circle 3 and being reassembled into the new password numeral with retaining gear ring 2, reinstalls by embodiment 1, changes sign indicating number and finishes.
