Description

Cipher key

Technical field

The utility model belongs to lockset used in the daily life, is specifically related to a kind of cipher key with antitheft function of keeping secret.

Background technology

Lockset miscellaneous in the market emerges in an endless stream, but always be unable to do without a fixing pattern: a key can only be opened a lock.So key need with a lot, not only carry inconvenience, and every key all has fixed shape, so just copy easily, antitheft confidentiality is not high, and in a single day key is lost, and can cause a lot of troubles, please be professional the unlock staff open or directly picking lock more renew lock, bring unnecessary economic loss to people.

The utility model content

The utility model is in order to solve weak point of the prior art, a kind of confidentiality height simple in structure, easy to carry, antitheft is provided, can have opened the cipher key of many locks.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: cipher key, comprise the shank of the key and key bar, key bar is inner fixedlys connected with the shank of the key, described key bar circumference is provided with several pivoted housings, pivoted housing and key bar matched in clearance, the pivoted housing circumference is provided with several and lock core marble meshes the projection and the groove of unblanking, the height of each pivoted housing upper protruding block and width dimensions are all unequal, key bar the inner is provided with and is meshed with lock core and stirs the convex-concave shifting block that lock core rotates, and the key bar outer end is provided with the axially movable positive stop lug boss of restriction pivoted housing.

The number that groove on described each pivoted housing circumference and projection are provided with is all equal, and groove and projection evenly are provided with at interval, and equal mint-mark has numeral or letter in the groove.

The outside dimension of described positive stop lug boss is less than groove floor circle diameter size.

Described key bar is a hollow structure.

Described the shank of the key is provided with perforation.

Adopt said structure, when unblanking, rotate pivoted housing, make groove and the projection and the key bar keeping parallelism of each pivoted housing, can unblank, in time spent not, arbitrarily pivoted housing is turned an angle, just can prevent that others from using this key unlocking, so just play good antitheft effect, and realize the function of key operated many locks; The numeral of mint-mark or alphabetical in the groove, people can be provided with different passwords according to different lock core marbles, not only antitheft maintaining secrecy, and simple operation, according to different lock core marbles different passwords is set, carries a key and just can drive a lot of locks, easy to carry; The outside dimension of positive stop lug boss is convenient to insert the lock core drawback lock less than groove floor circle diameter size; Key bar is that hollow structure had both alleviated key weight, saved material, again can be supporting with the central axis of lock core, be convenient to unblank; The shank of the key is provided with perforation, is easy to carry; The utility model confidentiality height simple in structure, easy to carry, antitheft, can open many locks, also needn't worry stolenly even lose, market prospects are good, are easy to apply.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1.

The specific embodiment

As depicted in figs. 1 and 2, cipher key of the present utility model, the key bar 2 that comprises the shank of the key 1 and hollow structure, the shank of the key 1 is provided with perforation 8, fixedly connected with the shank of the key 1 in key bar 2 the inners, key bar 2 circumference are provided with several pivoted housings 3, pivoted housing 3 and key bar 2 matched in clearance, pivoted housing 3 circumference are provided with several and lock core marble meshes the projection 4 and the groove 5 of unblanking, the number that groove 5 on each pivoted housing 3 circumference and projection 4 are provided with all equates, groove 5 evenly is provided with at interval with projection 4, in the groove 5 of each pivoted housing 3 in order successively mint-mark Arabic numerals 1 are arranged, 2,3,, or alphabetical a, b, c;Key bar 2 the inners are provided with and are meshed with lock core and stir the convex-concave shifting block 6 that lock core rotates, the depression position of convex-concave shifting block 6 is corresponding consistent with groove 5 and projection 4 respectively with the protrusion position, key bar 2 outer ends are provided with restriction pivoted housing 3 axially movable positive stop lug boss 7, and the outside dimension of positive stop lug boss 7 is less than groove 5 bottom surface circle diameter sizes.

During use, according to from outside to inside or order from inside to outside configure the consistent numeral of each pivoted housing 3 groove 5 and the shank of the key on the key bar 21 or letter as the password of unblanking, when unblanking, it is consistent with the password of setting just to rotate the password that each pivoted housing 3 makes it in the groove 5, unblank the not time spent, can arbitrarily rotate any pivoted housing 3, whole numeral or lexicographic order are upset, so just can prevent that others from using this key to open this lock.Can set the password different according to top method at lock with it to other model of the same race, aim at numeral or alphabetical in order to rotate pivoted housing 3, realize that a key opens the function of many locks, so just can realize unlatching only with such key to all locks of family.
