Abstract

The utility model relates to a coded key which comprises a key body. The utility model is characterized in that a sliding hollow shaft and a spring which can enable the hollow shaft to return to the original position are assembled on the key body; a plurality of dentiform codes which are corresponding to a lock core are penetrated on the hollow shaft, and positioning engaging teeth of a circumferential direction are arranged among the dentiform codes and between each dentiform code and the key body. The utility model has the advantages that when the key is lost or people are locked in a room by mistake, keys of other people with the same standard can be borrowed to unlock the lock after a coding process is finished; when the coded key is not used, the codes can be adjusted in a disorderly way; thus, even the coded key is lost, the people do not need to worry that the lock is unlocked by other people, and then, the trouble of replacing a new lock is avoided. The utility model has the advantages of security and secure and convenient use.

Description

Cipher key

The utility model belongs to a kind of key, particularly a kind of cipher key with function of keeping secret.

The lockset that is used for all kinds of doors such as door, security door, car door, cabinet door at present adopts cylinder lock mostly, and the situation of the key loss that in use happens occasionally is brought very big worry to the party, and the one, the door of locking can't be opened, and have to ask the professional to open; The 2nd, need change lockset again after opening, the person opens in order to avoid picked up surreptitiously.

The purpose of this utility model provides a kind of cipher key, key loss or mistake are locked when indoor, after the similar standard key that can use other people is encoded lock are opened, and cipher key can transfer password disorderly by the time spent, needn't worry that also other people open lock even lose, exempt the trouble of changing lockset again; Have confidentiality, safe and convenient to use.

The purpose of this utility model is achieved in that it comprises key body, and its improved technical scheme main points are: hollow shaft that assembling is slided on the key body and the spring that hollow shaft is resetted; Install a plurality of profile of tooth sign indicating numbers corresponding on the hollow shaft with lock core, between each profile of tooth sign indicating number and and key body between circumferential location engaging tooth is set.

Using method; The profile of tooth sign indicating number and the lock core number of key are corresponding, key is the unified standard part when dispatching from the factory, the profile of tooth sign indicating number of the corresponding lock core of key can mix up when dispatching from the factory, also can mix up by user oneself, method of adjustment is simple: earlier with the hand spring that contracts, make hollow shaft from key body, stretch out certain-length, thereby there is the location engaging tooth of one to two profile of tooth sign indicating number to throw off, because the circumferential various tooth length on each profile of tooth sign indicating number is different, thereby adjust the circumferential position of or several profile of tooth sign indicating numbers, arranged again in the type tooth position of each profile of tooth sign indicating number by turn, to password position, after openhanded the opening of compression spring, the circumferential position of each profile of tooth sign indicating number is fixed, and can open lock body.For password after preventing key loss is given away secrets, the time spent can not transfer password disorderly.

The utility model has the advantages that: can encode voluntarily, strong security, thereby key loss or mistake lock when indoor is opened lock after can using other people similar key code; The time spent with its password accent disorderly needn't not worry that other people open lock even lose to key yet.Exempt the trouble of changing lock body, carry a key simultaneously and can open many same lock of different known numbers.The utility model is not only applicable to open the lock body of coding lock core, is applicable to open the lock body that fixed lock core is arranged yet.When unlatching has the lock body of coding lock core, can adjust corresponding coding simultaneously with the coding lock core, use more convenient flexibly, security reliability is good.Unlatching has the lock body of fixed lock core, has good confidentiality and security reliability equally.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A generalized section of Fig. 1.

Fig. 3 is that the utility model cooperates the user mode figure with coding lock core lock body.

See Fig. 1,2, concrete structure is as follows: the hollow shaft 1 that assembling is slided on the key body 3, the affixed cap 5 of pressing of hollow shaft 1 one ends is equipped with back-moving spring 4 between by cap 5 and key body 3.The a plurality of profile of tooth sign indicating numbers 2 of suit on hollow shaft 1, each flute profile length difference on the circumference of each profile of tooth sign indicating number 2, corresponding with coding on the lock core.Between each profile of tooth sign indicating number and and key body 3 between circumferential location engaging tooth 6 is set.See Fig. 3, the utility model cooperates the lock body use principle with coding lock core as follows: the outer lock core 10 and the internal cylinder 11 of coding lock core are made up of the unit piece of a plurality of axially-aligned, assembling pellet shot from a slingshot 8 and spring 9 on each cell cube.Seal in the outermost pellet shot from a slingshot of spring hole, in case spring jumps out.Have the interlock pawl to be inserted on each unit piece of internal cylinder on the preceding interlock dish 12, suit can divide the shell of taking off 7 on the outer lock core 10; Pusher dog 14 and back interlock dish 15,13 whole connections of anti-dial axis.In the use as need to adjust the coding of lock core, shell is pulled up, one of the turn outer lock core to several unit pieces then, change its circumferential position, promptly form new coding, and the utility model also adjusts with it that corresponding codes gets final product.The utility model cooperates the tapered end of existing widely used ordinary fixed lock core, key not the time spent key code transferred disorderly got final product, during unlatching, key code is readjusted the password position of unlatching.

Claims (1)

1, a kind of cipher key, it comprises key body, feature is altogether: hollow shaft that assembling is slided on the key body and the spring that hollow shaft is resetted; Install a plurality of profile of tooth sign indicating numbers corresponding on the hollow shaft with lock core, between each profile of tooth sign indicating number and and key body between circumferential location engaging tooth is set.
