Description

technical field [0001] The invention relates to a lock, in particular to a padlock. Background technique [0002] Existing padlocks generally include a lock case with a first lock hole and a second lock hole, and a U-shaped lock bar with a long rod and a short rod, wherein the long rod is rotatably limited in the first lock hole, And it can move up and down relative to the first lock hole.

Problems solved by technology

This locking method is inconvenient to operate. During operation, you need to turn the padlock at an angle, align the lock lever with the door body, and then push the lock shell hard, or hold the bottom of the lock shell with the palm of your hand, and then press down with your fingers. The upper end of the lock lever, so that the span between the fingers and the palm rest is relatively large, it is not easy to use force, so it is inconvenient to lock

[0006] Although the key lock and combination lock are combined in the above-mentioned first patent, the locking and unlocking processes of combination lock and key lock are basically the same, and both are realized by moving the lock bar up and down, which has the disadvantage of inconvenient operation. , and the structure of its key lock is relatively complicated
