Design principle and method of anti-pulling spring of technical-unlocking resistant spring lock and key of anti-pulling spring

Abstract

The invention provides a non-fault-tolerant principle, and relates to a design method of an anti-pulling spring and a key corresponding to the anti-pulling spring according to the non-fault-tolerant principle. The non-fault-tolerant principle means that faults cannot be tolerated, no effect is achieved as long as no fault is caused, and opposite effects are achieved immediately once a fault is caused. The anti-pulling spring has the non-fault-tolerant characteristic, when a correct key is inserted into the anti-pulling spring in place, the anti-pulling spring has no effect, and when no correct key is inserted into the anti-pulling spring or the correct key is not inserted into the anti-pulling spring in place, a lock cylinder can be clamped by the anti-pulling spring and cannot rotate. The anti-pulling spring is popularized to be used, few improvements can be carried out on current spring locks in all types without increasing any equipment and cost, and anti-theft safety of the spring lock can be greatly improved.

Description

technical field [0001] The invention relates to the principle of non-fault tolerance and an anti-dialing pin and a corresponding key designed therefor. Background technique [0002] At present, there are many technical methods and special unlocking tools for unlocking tumbler locks in the society, such as: torque wrench to turn the lock cylinder, steel wire to pull the pin, vibrating unlocker, etc., so that a large number of tumbler locks completely lose the most basic function of the lock-- - Anti-theft, some tumbler locks with high protection level not only have cumbersome structure, complicated production process, high cost and high price, but also are extremely inconvenient to unlock and lock. Contents of the invention [0003] The purpose of the present invention is exactly in order to solve the above-mentioned problem, make pin lock cheap and fine, convenient, applicable, safe. [0004] The technical principle of the present invention to solve the above-mentioned pr...
