Description

The vernier Puzzle lock

The utility model is a kind of vernier Puzzle lock.

Lock is article commonly used and very necessary in daily life and the economic activity, and lock commonly used at present generally has cylinder lock, electronic code lock, also has Fingerprint Lock etc. in addition.The longest, the cylinder lock the most generally of history wherein, the secret agreement amount of cylinder lock is different decision of height by the pellet shot from a slingshot of installing in its lock body and the lock core, and, pellet shot from a slingshot in the cylinder lock is set in advance by producer, therefore, because the dual problem of management and technology makes cylinder lock that great repeatability be arranged, and that is to say that its size of key is very low.The key supporting with cylinder lock is not only comparatively heavy, and duplicates very easily, and this has also greatly influenced the confidentiality of cylinder lock.Coding lock then has password problem such as to forget easily.

The purpose of this utility model is: design a kind of can arbitrarily the setting and open sign indicating number approximately, thereby increase the vernier Puzzle lock of confidentiality, safety.

The utility model includes protocol related built-in sign indicating number approximately, external sign indicating number approximately and has the lock body part of the passage that cooperates with it respectively; Lock body part comprises and having and the built-in about code holes that approximately the sign indicating number channel position is corresponding and the shell of external about code holes, be equipped with on the shell and the lock shaft of sign indicating number channel parallel approximately, shell interior in addition with lock shaft on the corresponding lock pin in lockpin hole position; Two approximately the sign indicating number passage be connected with lock pin by two groups of verniers that are installed in the gathering sill separately respectively, the vernier return spring is arranged in the gathering sill; Two groups of vernier enable possitions are consistent with corresponding sign indicating number approximately with the locked position difference in height.

In the utility model, also can cooperate between lock pin and the lock shaft by groove, key etc.During use, at first built-in approximately sign indicating number of the external equipment of lock and external protocol related between the sign indicating number approximately, then built-in sign indicating number is approximately inserted in the corresponding passage of sign indicating number approximately and form sign indicating number approximately, when the insertion protocol compliant concerns external about yard in external about sign indicating number passage, the lock shaft in the lock body part and the position of pin are in the enable possition, rotate the handle that is connected with lock shaft and can open the door.Because the sign indicating number approximately of same lock can arbitrarily be provided with, thereby the utility model size of key is very big, its confidentiality is stronger.

In the utility model, lock pin can be following mode with being connected of vernier; Two groups of relative sides of vernier all have tooth bar, between two groups of verniers the one group of difference vernier that has gear are arranged, two verniers of position correspondence, the gear on the difference vernier, tooth bar engagement; Lock pin is parallel with vernier.Under this structure situation, drive a vernier by about sign indicating number and move, and then drive the difference vernier, lock pin is in respectively corresponding to lock shaft opens and locked position.

In said structure, lock pin is inserted on the lock shaft, also can above lock pin, install a fitting pin again additional, the hole on the lock shaft is a through hole, fitting pin is consistent with this through hole length, between the gathering sill of fitting pin and lock pin return spring is arranged.

Lock pin also can be following mode with being connected of vernier in the utility model: two groups of verniers are positioned at the same side of lock shaft, have pin-and-hole on the vernier respectively, wherein close in the pin-and-hole of one group of vernier of lock shaft to be inserted with one group of pin; One slide block that is positioned at gathering sill is arranged between pin and lock shaft, on slide block and the lock shaft facing surfaces outstanding key is arranged, corresponding groove is arranged on the lock shaft.

Perhaps, two groups of verniers have the contact, and are positioned at the same side of lock shaft, and relative two verniers constitute a switch, after each switch series connection, connect in the shell electromagnetic coil, have one corresponding with pin-and-hole on the lock shaft by the pin position of coil control.

The employed approximately sign indicating number of the utility model protocol related can be following form: built-in sign indicating number approximately and external sign indicating number approximately the lines shape of yard end face approximately are consistent.Built-in sign indicating number approximately can exchange with external sign indicating number approximately during use.Its employed passage of sign indicating number approximately is also interchangeable.

Be the convenient installation and the return mechanism of sign indicating number approximately, can following mechanism be installed in a side of sign indicating number passage approximately: it comprises a button, a side of button have with a duplex gear on the tooth bar of a gears engaged, have stage clip between button inner surface and the shell.

In addition,, also can have projection, and every group of projection below there is a return driving lever in the side of every group of vernier for ease of the vernier return.
