High-safety combination pad-lock with lock bar

Abstract

The invention discloses a kind of combination padlock, it is made up of heavy duty metal, it has expanded and heavy loaded lock pole or lock buckle, there also has anti-picking protection cavity used in the ends of the pole. The invention includes tumbler or conjugant, it can cooperate with the rotary number plate. It forms several radial extension rib through the tumbler and conjugant, each rib and the adjoining rib are separated with dissymmetrical arc, so the lock can't be prized. The invention also includes special cipher set and subassembly reset. The pole must passes through the slot of key hole in the lock in order to start the cipher set and reset mode, the subassembly cooperates with the bolt and joggles with the whorls to control the axial movement of the axis.

Description

technical field [0001] The present invention relates to a padlock, in particular, to a combination padlock configured for high security and high stability applications. Background technique [0002] Various lock structures have been developed and are widely used by individuals to prevent unauthorized persons from entering areas that have been enclosed and locked. While many locks are arranged to be opened by a key, digital combination locks have also been developed which are opened by specific known combinations. [0003] A particular type of combination lock, known for its ease of use, employs a plurality of independently rotatable dials, each dial comprising a number of indicia, usually numbers or letters, which determine the Password to unlock. Although such locks have been used for decades, prior art combination locks are often used in less secure areas because they do not prevent forced entry when excessive force is applied to the lock. [0004] In areas where high s...

AI Technical Summary

Problems solved by technology

In order to obtain a padlock with all the features desired by the user, prior art constructions often include a large number of small parts, each of which requires an expensive assembly process in order to generate the final product

Therefore, these prior art high security padlock structures are usually expensive to manufacture, so that these padlocks cannot be widely used by users.

[0006] Another problem that prior art high security padlocks generally have is that the prior art construction does not prevent contaminants from reaching the internal components of the padlock, causing damage to these components and making it easy for unauthorized persons to tamper with the padlock. Operation of the padlock

Although various measures have been taken to reduce the adverse effects caused by contamination reaching these components, these measures have not satisfactorily eliminated these problems

[0007] It is also often a problem with prior art high security padlocks that unauthorized persons can open these locks using lockpicking techniques

Especially since prior art products utilize keys for operation, unauthorized entry is a public problem
