Technical unlocking preventing lock cylinder for card key

Abstract

The invention discloses a technical unlocking preventing lock cylinder for a card key and relates to the technical field of anti-theft mechanical locks. The technical unlocking preventing lock cylinder comprises two marble nests which can mutually act and are correspondingly provided with array marbles, the card key which can be compressed on the marble nests, an upper cover and the like. Whetherthe marbles are aligned between the two marble nests or not is determined by different thicknesses of positions corresponding to the marbles, of the card key as a key, and further the aim of preventing unlocking or realizing unlocking is achieved. Compared with more marbles in an array, the marbles disclosed by the invention have large coding amount; and in addition, due to mutual shielding of more marbles and barrier of a protection wall, the state of certain marble is hardly explored and the really-strong technical unlocking preventing capability is realized. The technical unlocking preventing lock cylinder disclosed by the invention is suitable for lock bodies of various doors and cabinets, and is quite suitable for being matched with relatively-advanced electronic locks for security doors tor use; and besides, the card key better meets the carrying requirements of modern people.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of mechanical anti-theft locks, in particular to an anti-technical unlocking cylinder of a card key. Background technique [0002] The lock is generally composed of a lock body, a lock core and a key. Use the correct key to insert the lock core, so that every marble on the lock core will not block the lock core. When the lock core is turned, the lock tongue will be opened to unlock the wrong key. It cannot be matched with every marble properly. One or more marbles will form a blockage between the lock cylinder and the lock body, and the lock cylinder cannot be rotated and the lock cannot be unlocked. [0003] The existing lock cores and keys have the following problems: [0004] 1. Poor ability to resist technical opening: Technical opening refers to unlocking with a certain tool without a key. The principle is to extend the tool into the lock cylinder to press all the marbles one by one an...

Problems solved by technology

Another reason for the poor anti-technical opening ability is that the arrangement structure of the marbles in the current lock cylinder determines that only a dozen marbles can be used at most, resulting in relatively few available keys, which makes it difficult to detect and control the marbles when the technology is opened. not high enough

[0005] 2. The key is inconvenient to carry: the key of the current mechanical lock cylinder is not only the key carrier, but also the power source for unlocking. Too large or too small is not conducive to use and carry

A single carry is easy to lose, and multiple carry must add a keychain to form a larger string
