Abstract

Provided is a long pin tumbler lock. Significant improvements are conducted on a combination mode of a rotor and a stator in a lock. The mode that for a general pin tumbler lock, the rotor is located inside, the stator is located outside, and the rotor and the stator are connected with each other in a concentric, coaxial and matching mode is changed to the mode that for the long pin tumbler lock, the rotor is located front, the stator is located back, and the rotor and the stator are connected with each other in a concentric end surface matching mode, wherein the rotor is located front, the stator is located back, and the rotor and the stator are embedded in a lock cylinder support with a same axis in a sleeved mode; the axes of pin tumbler holes in the general pin tumbler lock are perpendicular to those of the rotor and the stator, the motion direction of the pin tumblers is perpendicular to that of a key, the perpendicularity in the two situation determines that the pin tumblers can not be made to be long, and changes that the axes of all the pin tumbler holes, penetrating through the rotor and the stator longitudinally in the long pin tumbler lock, are coincident and are evenly distributed around the axes of the rotor and the stator in parallel, and the motion direction of the pin tumblers is the same as that of the key are made. Accordingly, the pin tumblers can be made to be long, the actual length of a pin tumbler set of the long pin tumbler lock is 30 mm, the locking points are all smaller than 0.3 mm, each pin tumbler with the length of 30 mm has 100 locking points, and the number of combination of six pin tumblers is one trillion (please see the formula in the specification). If the lock is opened without the key, six ejector rods need to be inserted into the six pin tumblers to open the long pin tumbler lock with one trillion of combinatorial numbers of the locking points, and the long tumbler lock is difficult to open.

Description

Long marble is locked

Technical field

The present invention is " long marble lock ", belongs to cylinder lock field.More conventional cylinder lock unlike: by change lock rotor and stator between combination, make pellet axis and rotor stator axis in the same way, the direction of motion of pellet and the direction of motion of key are in the same way, these two determine pellet in the same way and can do very long, so be referred to as " long marble lock " (spring length is the key point determining locking number of combinations size).

Background technology

Conventional cylinder lock all adopts rotor in interior, stator concentric co-axial line structure design outside, the combination between rotor and stator is made to be that concentric co-axial line is connected mode, pellet axis and rotor stator axes normal, the direction of motion of pellet is vertical with the direction of motion of key, these two vertically just determining pellet cannot do length, can find out the concavo-convex difference that pellet plays regulatory role on the key from it, only has high, medium and low three state, with regard to the routine lock of 6 pellet groups, its locking number of combinations only has 36=729.Pellet group is all in again on same of the same line, give and bring convenience without spoon unlatching, in order to deal with problems, everybody makes an effort on anti-dial, have and increase pellet group number, have and Special-shaped marble is set, have and arrange that key mouth seals up a door, have and engulf master key, though all this kind can improve beneficial effect, limited.

Summary of the invention

The present invention is " long marble lock ", belong to cylinder lock field, combination just between lock rotor and stator redesigns, be intended to the effective length that large degree increases pellet, increase locking number of combinations, strengthen and open difficulty without spoon, concrete technical scheme is: by rotor front stator after be nested in the lock core support of same axis, combination between stator with support is concentric being fixedly connected with, combination between rotor with support is that concentric fit is connected, combination between rotor and stator is that coaxial terminals plane is connected, longitudinally run through the dead in line of each marble hole of rotor stator and be distributed on rotor stator axis and parallel, the axis of pellet push rod on the key pellet played regulatory role and the dead in line of pellet, the direction of motion of key and the direction of motion of pellet are in the same way, what therefore pellet can do is very long.Key is inserted in " long marble lock ", the pellet regulating corresponding different length is removed by the pellet push rod of different length on the key, make the pellet of each pellet group in lock be exactly the opening point locked in conjunction with end face and the binding end planes overlapping between rotor and stator, otherwise be all locking state.In addition the 30mm long tubular gear that the lock core support of " long marble lock " is provided with for lock core axial adjustment (is with carry-over bar by the long tubular gear of 30mm in lock body, lock is opened or locking), thus make lock core can axial adjustment 20mm, with the security door making lock core can adapt to 50mm-70mm different-thickness.

The invention has the beneficial effects as follows: specifically key is inserted in " long marble lock ", the pellet regulating corresponding different length is removed by the pellet push rod of different length on the key, make each pellet group pellet in conjunction with end face and the binding end planes overlapping between rotor and stator, the opening point locked exactly, otherwise be all locking state.Because the binding end plane between rotor with stator coordinates very tight, the binding end of pellet, without the reason of rounding, makes locking point very precisely (actual verification locking point <0.3mm).Again owing to longitudinally running through the dead in line of each marble hole in rotor stator, and be distributed on rotor stator axis and parallel, the direction of motion of pellet and the motion defence line of key in the same way, which dictates that pellet can do very long (the bullet subset length of actual lock is 30mm).The pellet that 30mm is long just there is 30mm/0.3mm=100 locking point, the locking point number of combinations of 6 pellet groups is 100,6=1 trillion, and 6 pellet groups each be all independently, if open needs 6 push rods without spoon to insert in 6 marble holes " long marble lock " difficulty going to tune to open 1,000,000,000,000 locking number of combinations respectively.Comparative result is: " long marble lock " is more antitheft than conventional cylinder lock, safety and reliability; Lower than simple costs such as light-operated combination padlock, Fingerprint Lock, and other multiple lockset can be made, more practical; In addition the lock core support of " long marble lock " is provided with the 30mm elongate holes for lock core axial adjustment, and with the 30mm long tubular gear (by 30mm long tubular gear be lock open or locking at carried interior band carry-over bar) of rotor one, thus make lock core can axial adjustment 20mm, adapt to 50mm-70mm different-thickness security door to make lock core.
