Description

A kind of mechanical lock

Technical field

This utility model relates to a kind of mechanical lock, belongs to mechanical field.

Background technology

Lock core uses multinomial anti-theft technique, and multiple abnormity is anti-pulls out pellet, stops technical opening, coordinates unique pellet to design with blade construction, has the security performance of the highest anti-technical unlocking.Lock gall is built with accurate number pellet and Special-shaped marble structure, and when carrying out technical opening, number pellet and Special-shaped marble can be automatic locking when must stir simultaneously, so that technical opening is come back after a vain attempt.Lock core have employed multiple abnormity hoodle Multiple Combination, at most can work out billions of kinds of key numbers, thus feasible region zero opens (1/1006000000th) mutually.Lock core adds lateral inner pressed side column lift sub pin device, substantially increases and prevents violence from turning round by force ability.

The national standard of theftproof lock is divided into point " common protection level " and " senior protection level ", and the former represents with letter " A ", and the latter represents with letter " B ".What is called on the market surpasses B level and C level is some businessmans oneself definition, should can be regarded as B level lock strictly speaking.1.A level lock core, prevents the skilled unlocking time no less than 1 minute, prevents the destructive opening time no less than 15 minutes.A level lock core is old-fashioned lock core, key is that cross is plate or selenodont has convex spoon groove key, single or double has row's spill spoon groove, and this kind of key thief just can be able to open with tinfoil within several seconds, if your family or this key lose no time to change.A level lock core cannot guard against thief.B level lock core, prevents the technology unlocking time no less than 5 minutes, prevents from impacting the opening time no less than 30 minutes.B level lock core key is plate or selenodont, and B level lock key is more complicated than A level key, and key slot is that single or double has two row's spills or column type multiple spot spill spoon hole.3. surpassing B level lock core, the technical opening time was more than 270 minutes.Super B level lock core key is plate, and spoon groove is one side or two-sided has two row's spills to add milling groove structure in S-shaped, or inside and outside pair of Serpentis type.Being the most complicated lock core, be also safest lock core, the instrument opening time even cannot open more than 270 minutes.
