ABSTRACT:
A structure of padlock is provided. The padlock comprises a hollow cylinder body, a U-shaped shackle arms and a locking mechanism which is composed of a pair of sliding members symmetrically arranged in the cylinder body and movably connected to a disk member via a pair of lever members and urged outwardly by a pair of compression springs. The sliding members normally position at a pair of locking holes for facilitating an automatic locking up the shackle arms into the cylinder body, and the shackle arms are unlocked by rotating the disk member clockwise with a key so as to actuate the sliding members moving centralizedly. The symmetrical arrangement of the components in the locking mechanism provides the stability as well as the durability of a padlock.
