Novel anti-pull-cut padlock capable of replacing lock cylinder structure

Abstract

The invention discloses an anti-pull-cut padlock capable of replacing a lock cylinder structure. Dual fixing of a protective cover fastening lock nail and a protective cover lock pin is adopted in thevertical direction, a lock cylinder main body is dually fixed through a lock cylinder fastening piece and lock cylinder fastening screws in the transverse direction, fixing is conducted through a lock cylinder lock pin in the longitudinal direction, thus a lock cylinder can be prevented from falling off in the three directions, and the anti-pull performance of the lock cylinder is greatly enhanced accordingly. In addition, in an opening state of the padlock, a lock hook is pulled out from a lock hook hole in a lock body, after a positioning bead and a positioning spring are taken out, the protective cover fastening lock nail can be unscrewed, then the entire lock cylinder structure is taken out, finally the lock cylinder lock pins and the lock cylinder fastening screws in the longitudinaldirection and the transverse direction of the lock cylinder structure are taken out to replace the lock cylinder, and the rest of parts of the padlock can still continue being used so that the cost of lock cylinder replacing can be greatly saved; and therefore, the structure is more reasonable, pull-cut prevention and lock cylinder replacing can be both achieved, and the cost of lock cylinder replacing is low.

Description

technical field [0001] The present invention relates to a padlock. Background technique [0002] At present, most of the padlocks on the market have the following two problems: one is that the lock cylinder in the padlock cannot be removed and replaced, and the other is that the tensile performance of the lock cylinder and the lock hook of the padlock is not very good. There are relatively few padlocks with good tensile properties of replacement lock cylinders, lock cylinders and lock hooks. Therefore, the present invention intends to use a new pull-proof structure to realize the padlock and at the same time have the function of preventing pull-break and changing the lock cylinder. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a more reasonable structure of a padlock with an anti-pull and breakable lock cylinder structure, and the cost of replacing the lock cylinder is low. [0004]...
