Secondly, since the latch 141 is mainly protected by the convex baffles on both sides of the rotating block 12, the protruding portion is easily bent, causing the latch 141 to be exposed, so that it is easily cut or cleaved.
- the padlock protection device has a matching sliding cover and a base, which is firmly matched and high in strength, and the sliding cover protects the latch from the inner cavity thereof, thereby effectively preventing violent damage.
- the present invention provides a padlock protection device applied to a door having a hanging nose, the hanging nose having a lock R hole, and the lock R hole is connected to the lock bolt of the padlock to realize locking of the door.
- the padlock protection device includes:
- the slide cover is provided with a locking member facing the base and having a lock R hole, and when the slide cover covers the base, enables the padlock to enter from the open end and pass through the locking member
- the lock R hole and the lock R hole of the hanging nose enable locking of the locking member and the hanging nose.
- the padlock protection device cooperates with the sliding cover and the base to form a shell-like structure, the relatively weak latch and the hanging nose can be fully protected, and the latch and the hanging nose can be completely placed on the sliding cover and the base.
- tools such as steel brazing sticks and hydraulic cutting pliers are not easy to break into the sliding cover; moreover, the sliding cover and the base slide
- the sliding cover and the base itself have a shell-like overall structure, and there is no breakthrough for the above-mentioned tools; the sliding up and down of the sliding cover cooperates with the locking and unlocking of the padlock, so that the opening and closing of the machine is also convenient.
