Digit password lock core

Abstract

The invention relates to a digit password lock core used in safety anti-theft systems and lock products. More than two cylindrical digit wheels with the same size and shape are installed on a digit wheel shaft with a positioning pit in a section-to-section way. The digit wheels are respectively provided with an efficient point which is equal distance away from the axis. The efficient points are utilized in the following two ways: 1, the efficient points are drilled into round holes for direct use; 2, conductors are arranged in the holes, and when each digit wheel is rotated, the efficient points of the digit wheels can coincide on a same straight line. Each digit wheel is sheathed with a digital film of which the external circle surface is marked with digits 0-9 in a staggered way; and at this time, the coincidence of the efficient points and the indication of the digits constitute the core of the digit cipher lock core. The lock core is provided with a mechanical digit shift wheel, a digit shift key and an electromagnetic digit shift wheel of a digit shift device, a ball and a spring of a positioning device, a seal ring and a zero reset blade. The coincidence and staggering of the efficient points of the lock core are utilized to control the open / closed state of liquid, gas and circuit, thereby achieving the goal of controlling the open / closed state of the plunger latch.

Description

Technical field [0001] The digital password lock cylinder of the present invention is a device used in security and anti-theft systems and lock products. When the device is used in anti-theft systems and lock products, no key is needed to unlock the lock, and the lock can be opened only by adjusting the password to the correct position when unlocking. Background technique [0002] Locks are the closest to people's daily life. At present, it is recognized that a key can open a lock. No matter how the geometry of the key and the lock body changes, the key must be inserted into the lock body when unlocking. The effective part of the key squeezes the atomic interface inside the lock body to push and pull. , The interface part of the swivel can open the lock. And the effective part overlapping probability of two different keys is higher and easily causes misopening. It is inconvenient to carry the key with you, and it is lost and irreversible. The anti-theft device or lock eq...

AI Technical Summary

Problems solved by technology

However, the effective parts of two different keys have a high probability of overlapping, which is easy to cause accidental opening.

It is inconvenient to carry the key with you, and it may be lost and irreversible

The anti-theft device or lock equipped with a digital password lock cylinder is different. You only need to write down the password to unlock it, and the chance of password overlap is extremely low.
