Abstract

A high security key lock comprises a lock body and a lock core, wherein the cylindrical lock core is inserted into a hole of the lock body in a sliding fit manner, and an axial key hole is formed in the lock core; and a key matched with the key hole. At least two rows of pin holes are arranged on the lock body and the lock core respectively, and a separation plate is arranged between the end parts of the pin holes in each row in the key hole; the key is provided with at least two rows of corresponding key teeth, and an isolation groove matched with the isolation plate is arranged between each row of key teeth; the adjacent end surfaces of the two sections of marble posts in each marble hole are curved surfaces. The utility model adopts two rows or three rows of marble columns, and the key matched with the marble columns also has at least two rows of key teeth, because the number of keys provided by the two rows of key teeth is greatly increased, the probability that one key can open two locks is extremely low; the keys in parallel have different heights, so that the keys can not be copied by using the existing tool, and the security of the lockset is greatly improved.

Description

A kind of high secret spoon lock

Technical field

The utility model relates to cylinder lock and the key supporting with it, particularly a kind of high secret spoon lock.

Background technology

Common all kinds of cylinder locks generally have only row's pellet shot from a slingshot post, supporting the corresponding spoon tooth of a row are arranged on the key with it.Its shortcoming is: the key of its single spoon tooth is easy to duplicate on common electronic Bitting machine, even uses small tool also reproducible by hand, and its confidentiality is very poor.Cause stolen case to happen occasionally because of door or automobile key are stealthily duplicated by the bad person, cause damage for society and family.

In addition, because single pellet shot from a slingshot post quantity is few, the number of its permutation and combination is also little, the situation that a key can be driven two locks usually occurs, has also reduced its confidentiality.

Summary of the invention

The purpose of this utility model just provides the secret spoon lock of height that a kind of key is difficult for being replicated.

The technical solution of the utility model is: comprise lock body and lock core, columniform lock core is slidingly matched and inserts in the hole of lock body, and axial keyhole is arranged in lock core; Also have and the supporting key of this keyhole, on lock core and lock body, corresponding pellet shot from a slingshot hole is arranged respectively, two sections pellet shot from a slingshot posts and spring are all arranged in each pellet shot from a slingshot hole, and respectively there are at least two rows in the pellet shot from a slingshot hole on described lock body and lock core, between the end in every row's pellet shot from a slingshot hole a division board is arranged in described keyhole; Described key has at least two corresponding row's spoon teeth, between every row's spoon tooth the isolation channel that cooperates with above-mentioned division board is arranged; The adjacent end face of two sections pellet shot from a slingshot posts in every pellet shot from a slingshot hole is a curved surface.

Described shell hole is two rows, and described division board is one, and corresponding with it has two to arrange the spoon teeth on the key.

Described pellet shot from a slingshot hole is three rows, and described division board is two, and corresponding with it has three to arrange the spoon teeth on the key.

One side of described key has a locating slot.

The utility model adopts two rows or three row's pellet shot from a slingshot posts, and the key supporting with it also has at least two row's spoon teeth, because two rows (three rows) spoon number of keys that tooth provided increases greatly, the probability that key can be driven two locks is minimum; And spoon tooth height side by side is different, uses not reproducible of existing instrument, has only production firm can make with special-purpose machine, has improved the confidentiality of lockset greatly, has avoided because key is replicated cause stolen.

The specific embodiment

Referring to Fig. 1-Fig. 6, the utility model comprises lock body 1, lock core 2 and key 3, and columniform lock core 2 is slidingly matched and inserts in the hole of lock body 1, and axial keyhole 4 is arranged in lock core 2; Key 3 is supporting with keyhole 4, and the corresponding pellet shot from a slingshot hole 5 that respectively has two rows to be parallel to each other on lock core 2 and lock body 1 also can have three to arrange pellet shot from a slingshot holes 5 for the bigger lock of volume.Pellet shot from a slingshot hole 5 among every row can be arranged side by side, also can mutual dislocation.Two sections pellet shot from a slingshot posts 6 and spring 7 are all arranged in each pellet shot from a slingshot hole 5.Between the end in the every row's pellet shot from a slingshot hole in described keyhole 4 division board 8 is arranged, its effect is that the pellet shot from a slingshot end that will extend in the keyhole keeps apart, and influences each other between every row's elastic force post avoiding.Described key 3 has two corresponding row's spoon teeth 31 (its spoon tooth row number is corresponding with pellet shot from a slingshot hole row's number on the lock body), between every row spoon tooth the isolation channel 32 that cooperates with above-mentioned division board is arranged.Also can have a locating slot 33 in a side of key 3.The fin corresponding with it 41 arranged in keyhole 4.

The adjacent face of two sections pellet shot from a slingshot posts 6 in each pellet shot from a slingshot hole is a curved surface, so that do not produce obstruction to unblanking.

The utility model can be used for all kinds of locksets, also comprises two-sided key (promptly the opposite face at row's key bit also has row's key bit) or four sides key (promptly having 4 row's key bits to be mutually 90 °) and the lock body and the lock core that match with them.
