Abstract
The invention relates to a method for preventing a marble lock and a key from being mutually unlocked. The marble lock comprises a lock body and a lock cylinder; the lock cylinder is provided with 2-20 rows of marble holes. The method comprises the following steps: (1) four different marble starting distances, namely A, B, C and D are designed in the lock cylinder and meet the following conditions that B-A is less than (D/2), C-B is less than (D/2) and A-D is less than (D/2), wherein d is the distance of two adjacent marble holes; and (2) key tooth types of different starting distances are correspondingly designed. The invention adopts a starting distance staggered method and A, B, C and D types of keys cannot be mutually unlocked, thereby theoretical number of permutations can be improved by four times.
Description
(1) technical field
The present invention relates to a kind of method that is used to prevent mutual opening of spring locks.
(2) background technology
The problem of opening mutually of lock be always a difficult problem, particularly cylinder lock of puzzlement lock technology because of the restriction of the sum of errors marble amount of pellet shot from a slingshot itself, make that to open problem mutually always more serious.As the computer key of 5 recessed teeth groove, can only arrange with 4 different pellets shot from a slingshot, theoretical tooth number has only 5 biquadratic, promptly 625 kinds, does not reach application request far away.
(3) summary of the invention
Technical problem to be solved by this invention is to provide a kind of method that effectively prevents mutual opening of spring locks.
The described method that is used to prevent mutual opening of spring locks, described cylinder lock comprise lock body, lock core, and lock core is provided with 2～20 row's pellet shot from a slingshot holes, comprising:
(1) four kinds of initial distance A of different pellets shot from a slingshot of design in the lock core, B, C, D, and satisfy following condition:
B-A＜(d/2), C-B＜(d/2), A-D＜(d/2), wherein d is the distance in adjacent two pellet shot from a slingshot holes;
(2) the key tooth form of the different initial distances of respective design.
The present invention is method because the initial distance of employing staggers, and A, B, each key of C, D can not held mutually, thereby the theoretical number of permutations is brought up to original four times.
(4) description of drawings
Fig. 1 is the schematic diagram of the method for the invention.
(5) specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but protection scope of the present invention is not limited to this.
With reference to Fig. 1, a kind of method that is used to prevent mutual opening of spring locks, described cylinder lock comprises lock body, lock core, lock core is provided with 2～20 row's pellet shot from a slingshot holes, comprising:
(1) four kinds of initial distance A of different pellets shot from a slingshot of design in the lock core, B, C, D, and satisfy following condition:
B-A＜(d/2), C-B＜(d/2), A-D＜(d/2), wherein d is the distance in adjacent two pellet shot from a slingshot holes;
(2) the key tooth form of the different initial distances of respective design.
Computer key with 5 recessed teeth groove is an example, and owing to A, B, four sections of keys of C, D can not be opened mutually, thereby theoretical tooth number has the 625*4=2500 kind.
Claims (1)
1, a kind of method that is used to prevent mutual opening of spring locks, described cylinder lock comprise lock body, lock core, and lock core is provided with 2～20 row's pellet shot from a slingshot holes, it is characterized in that comprising:
(1) four kinds of initial distance A of different pellets shot from a slingshot of design in the lock core, B, C, D, and satisfy following condition:
B-A＜(d/2), C-B＜(d/2), A-D＜(d/2), wherein d is the distance in adjacent two pellet shot from a slingshot holes;
(2) the key tooth form of the different initial distances of respective design.
