Description

Closed-hole type ratchet piece lock core and key

Technical Field

This reality is new belongs to tool to lock technical field, especially relates to a obturator formula ratchet piece lock core and key.

Background

The lock core is a main part for controlling the lock to be opened and is a core part which is matched with a key to drive the lock tongue to rotate. According to the GAT73-2015 mechanical anti-theft lock regulation issued by the ministry of public security, the national standard of the anti-theft lock is divided into A, B, C three levels by letter representation, wherein the technical opening time of the A-level lock cylinder is not less than 1 minute, the technical opening time of the B-level lock cylinder is not less than 5 minutes, the technical opening time of the C-level lock cylinder is not less than 10 minutes, and the safety level of the C-level lock cylinder is highest at present.

A level lock is single-row marble lock, and it is common generally to have a word lock, cross lock, crescent moon lock etc. and its theftproof performance is poor, and the opening time generally is about several seconds to two minutes, therefore well coordination publishes the consumption warning title, and burglary-resisting door A level lock just can open at tens of seconds even several seconds, calls for the consumer in time to change safer B level lock. In 2011, a thief opens the anti-theft lock by using a new technology commonly called a tin foil unlocking method, the unlocking process can be completed within a few seconds, the tin foil unlocking needs a special tin foil tool, and the tin foil can be opened quickly because the toughness of the tin foil is deformed along with the tooth patterns of the lock teeth of the pin tumbler lock and is occluded on the tooth patterns.

The B-level lock is a double-row marble lock, namely, the inside of the B-level lock is provided with double rows of marbles, so that the technical unlocking difficulty is increased, but the principle is similar to that of the A-level lock, so that the unlocking can be finished in a short time by adopting a tin foil unlocking method; aiming at the situation of tin foil unlocking, a B-level lock core is improved, namely an ultrasonic B-level lock is provided, and the ultrasonic B-level lock is generally a double-sided double-row marble groove and is provided with a blade or a curve beside the ultrasonic B-level lock seen from a key, so that the difficulty of tin foil unlocking is increased, but the B-level lock is complex in structure, large in number of parts, high in manufacturing cost and expensive in price.

The principle of the C-level lock, namely the blade lock, is that different blades with different angles in the lock core are rotated and aligned by using the teeth with different angle changes of the inclined surface on the key, so that the lock core is rotated and opened. At present, the blade lock on the market has a complex structure, more than 100 parts, high manufacturing cost and high price, and meanwhile, an unlocking tool specially aiming at the blade lock, namely, the foam unlocking tool appears on the market.

In order to solve the technical problems of the existing lock cylinder, the applicant develops a wheel chip lock cylinder after years of research and development, the lock cylinder needs to correct the rotation angles of all code rings, the technical opening difficulty is high, and the safety level is high. The lock core has the problems of more parts, complex structure, high manufacturing cost, easy blockage of the lock hole and the like, so the applicant designs the closed-hole wheel sheet lock core on the basis of the wheel sheet lock core.
