Abstract

The utility model relates to an improved padlock structure; mainly, one side of a padlock body is provided with a lock core barrel and a containing hole. The padlock body is provided horizontally with a column hole which is touched with the containing hole, and the interior of the horizontal column hole is provided with a latch and an elastic element. The latch is supported by the elastic element, so the bolt end of the latch passes through the space of cutting grooves on the other side. Through the annular teeth and a through groove between the column hole and the containing hole, the latch is engaged with a gear in the containing hole. The center of the gear is sheathed with the cutting groove faces on the tail end of the rotary shaft of the rotary lock core of the lock core barrel. A key is used for driving the rotary lock core to rotate in the padlock, and simultaneously, the gear drives the annular teeth of the latch to move along the column hole. Therefore, the bolt of the latch is driven and guided to move between the cutting grooves on the other side of the padlock body; thus, a hinge hook part which is inserted into the cutting grooves is locked fixedly.
