Abstract

The utility model relates to a three protection cipher padlock which comprises a lock seat (1), a lock cover (2), a lock ring (3), screws (4), a cipher disk (5), lock pins (6), a lock seat scale (7), a cipher disk scale (8), a true key groove (9) and a false key groove (10). The lock ring (3) is locked by using the cipher disk (5) and the lock pins (6) on the lock ring (3). The utility model solves the problems that the present padlock opened by a key can be prized easily, a key hole is damaged, the key is lost, the cipher lock can be decoded easily by emitting the rhythmic sound when the cipher disk is rotated, etc. The three protection cipher padlock does not need a cylinder and a spring, has the advantages of simple structure, easy fabrication and low cost, and is an ideal lockset for families, units and various public spaces.

Description

Three anti-cipher hang locks

A kind of three anti-cipher hang locks belong to the key-free lock field.

At present, the padlock majority that people use all is by key operated padlock, but there is following defective in this lock because structure is limit.The one, intensity difference is easily decreased by sled, and the 2nd, pour into slicker solder in the pellet shot from a slingshot hole, and key is easily copied, and the 3rd, key carries inconvenience, and key is easily lost, and the 4th, the easy blocked destruction of lockhole can not be opened.

For addressing the above problem, people have invented a kind of cipher hang lock, but this cipher hang lock is because of still adopting billiards structure, thereby number unlatching probability is bigger, exist easily by sled damage problem, and combination disk sends rhythmical sound when rotating, password easily is decrypted from the sound that rotates.

The purpose of this utility model is: provide a kind of without pellet shot from a slingshot and spring, have true and false two kinds of keyways on the combination disk, open no sound, be difficult for sled and decrease, decode three minimum anti-cipher hang locks of probability.

Technical solution of the present utility model is: a kind of three anti-cipher hang locks, it comprises lock (1), locking closure (2), lock ring (3), screw (4), combination disk (5), lock pin (6), lock scale (7), combination disk scale (8), true keyway (9), false keyway (10), it is characterized in that: lock (1) one side four combination disk (5) are housed, lock ring (3) is housed in the combination disk (5), and the upper end of lock (1) is fastened with locking closure (2) with screw (4).Be connected with four lock pins (6) on lock ring (3) and the garden post that combination disk (5) matches.Be carved with lock scale (7) on the surface that combination disk (5) one sides are housed of lock (1), be carved with combination disk scale (8) on the post surface, garden of combination disk (5).Have a true keyway (9) and two false keyways (10) on the combination disk (5).

The utility model has the advantages that: overcome existing padlock and easily decreased by sled, key is easily lost and combination disk is sent the defective of rhythm sound when rotating, and does not adopt pellet shot from a slingshot and spring, and the code breaking probability is minimum, and simple in structure, and is cheap.

That the utility model will be further described is as follows below in conjunction with accompanying drawing:

Accompanying drawing 1 is three anti-cipher hang lock front views;

Accompanying drawing 2 is three anti-cipher hang lock left views;

Accompanying drawing 3 is the structural representation of combination disk.

1 lock, 2 locking closures, 3 lock rings, 4 screws, 5 combination disk, 6 lock pins, 7 lock scales, 8 combination disk scales, 9 true keyways, 10 false keyways.

The utility model is to have four grooves that combination disk (5) is installed on one side of lock (1), and on the side surface on this limit, be carved with lock scale (7), also be carved with on the post surface, garden of combination disk (5) and the corresponding combination disk scale (8) of lock scale (7), combination disk (5) is packed in the corresponding groove of lock (1), and the true keyway (9) of four combination disk (5) is aimed at one by one, again the lock pin (6) on the lock ring (3) is aimed at the true keyway (9) on the combination disk (5), and skewer is gone in the centre bore of combination disk (5), then locking closure (2) is penetrated lock ring (3), be fixed in the upper end of lock (1) and firm welding by screw (4).

During use, after lock ring (3) aimed at hole, garden on the locking closure (2) and press, rotate the position of four combination disk (5) arbitrarily, lock pin (6) on the lock ring (3) is promptly blocked by combination disk (5), can not move up, make lock (1) and lock ring (3) be connected as a wholely, and can't be decreased by sled by firm.During unlatching, as long as rotational password dish (5) makes it aim at own fixed number, then the true keyway on four combination disk (5) is promptly aimed at the lock pin (6) on the lock ring (3), and lock just can be opened.

For preventing that password is decrypted, on lock (1) and combination disk (5), be carved with many lock scales (7) and combination disk scale (8) respectively, and on combination disk (5), have two false keyways (10) and a true keyway (9), make the decoding of password be reduced to bottom line.
