Abstract: A tubular lock for push locking has a lock housing, a switching handle mounted in a front end portion of the lock housing, an upper pin seat and a lower pin seat mounted in the lock housing and the switching handle, and multiple pin assemblies and a core shaft mounted in the upper pin seat and the lower pin seat. A key is only needed when unlocking the tubular lock, and then the tubular lock can be locked by pushing the core shaft. The tubular lock can be used to latch a pivotal mechanism. When the tubular lock is in an unlocking state, the user can switch the latch to the locking angular position or an unlocking angular position by turning the switching handle without using the key. Therefore, flexibility and convenience in using the tubular lock can be efficiently improved.

Abstract: An anti-vandal padlock has a base, a buckling unit, two anti-sawing sleeves, a ball, and a locking mechanism. The base has a mounting passage and an annular groove formed on an inner surface of the mounting passage. The buckling unit has two straight segments. The second anti-sawing sleeve is rotatably and axially-movably mounted in the mounting passage, and has a ball hole. The ball is mounted in the second anti-sawing sleeve and is capable of protruding out of the ball hole. In the locked state, the locking mechanism makes the ball engage in the annular groove to limit movement of the second anti-sawing sleeve, such that the buckling unit cannot be detached from the second anti-sawing sleeve. The two anti-sawing sleeves are rotatably mounted on the two straight segments such that the buckling unit cannot be sawn off and has a better anti-theft ability.

Abstract: A tubular lock assembly has a tubular lock, a cover, and a disassembling unit. The tubular lock has an annular keyhole and a cover screw hole enclosed by the keyhole. The cover is detachably assembled with the tubular lock, and has a covering board segment, a screw rod segment, and a first fitting segment. The covering board segment covers the keyhole. The screw rod segment is detachably screwed in the cover screw hole of the tubular lock. The first fitting segment is formed on the covering board segment. The disassembling unit has a second fitting segment. The second fitting segment corresponds in shape and size with the first fitting segment of the cover, such that the second fitting segment is adapted to engage with the first fitting segment, and the disassembling unit is capable of rotating the cover.

Abstract: A wafer padlock has a lock body, a limiting wafer, multiple locking wafers, and a shackle. The limiting wafer and the locking wafers are arranged in the lock body at spaced intervals. One of two ends of the shackle is selectively engaged with the lock body, and the other one of the two ends of the shackle is inserted in the lock body and extends through the limiting wafer and the locking wafers. The wafer padlock is unlocked by inserting a key into at least one key hole formed in the lock body. There is no need to turn the key and no need to enter code numbers one by one. Unlocking of the wafer padlock is quick and convenient. The wafer padlock has simple structures and high security for locking items.
