Description

Technical Field

[0001] The invention belongs to the technical field of locks, and in particular relates to a lock bead combination and a padlock. Background Art

[0002] Padlocks are convenient and flexible to use and have a wide range of uses. They can replace other locks, but other locks cannot replace padlocks. They are an ideal anti-hazard lock. However, padlocks must be interlocked with the convex hole parts of the closed object to play a locking role. They do not have the function of closing and opening from the inside and outside, so they cannot be used in some occasions.

[0003] There are many varieties and specifications of padlocks. Generally, the size of the lock is determined by the width of the lock body, the purpose of the lock is determined by the height of the lock beam, and the series of the lock is determined by the opening method of the padlock, such as straight opening, horizontal opening, top opening, and double opening.

[0004] Commonly used padlocks generally adopt two opening methods: vertical opening and horizontal opening.
