Abstract: A combination lock for preventing unintentional dialing of character discs has a lock housing and a combination assembly. A cover panel of a front cap of the lock housing has at least three disc-hole sets each of which has at least one disc hole. The combination assembly is mounted in the lock housing and includes at least three lock core assemblies, each of which includes a shaft and at least one character disc mounted on the shaft. The at least one character disc of one of the lock core assemblies and the at least one character disc of an adjacent one of the lock core assemblies are arranged in staggered positions. When one of the at least one character disc is dialed, other character discs surrounding the character disc to be dialed is not unintentionally dialed, which allows convenient use of the combination lock.

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 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.

Abstract: An adjustable buckle lock has a hook unit, a fixing unit, a wrench unit, an adjustment assembly, and a buckling ring unit. The hook unit can be securely mounted on a first locked object, and the fixing unit can be securely mounted on a second locked object. A pivotal end of the wrench unit is pivotally mounted on the fixing unit. The adjustment assembly is mounted on the wrench unit, and the buckling ring unit is pivotally mounted on the adjustment assembly and selectively hooks on the hook unit. With the moving of the buckling ring unit controlled by the adjustment assembly, the distance between the buckling ring unit and the hook unit is changed, and thus the pulling force for the buckling ring unit hooking on the buckling ring unit is adjusted, which ensures the first locked object and the second locked object are sealed together by a suitable force.

Abstract: A buckle lock assembly has a hook unit, a fixing base, a wrench unit, a buckling ring unit, and a lock. The hook unit is adapted to be securely mounted on a first locked unit. The fixing base is adapted to be securely mounted on a second locked unit and has a locking segment. The wrench unit is pivotally mounted on the fixing base. The buckling ring unit is pivotally mounted on the wrench unit and selectively clasps the hook unit. The lock is securely mounted on the wrench unit and has a locked state and an unlocked state. In a locked state, the lock engages with the locking segment to limit the wrench unit pivoting relative to the fixing base. In an unlocked state, the lock disengages from the locking segment to allow the wrench unit to pivot relative to the fixing base.

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 tubular has a hollow housing, a lock core, a pin seat, multiple pin assemblies, and a covering assembly. Multiple upper through holes are separately formed through a head portion of the lock core. Multiple lower through holes are separately formed through the pin seat and align with the upper through holes of the lock core respectively. An assembler assembles the housing, the lock core, and the pin seat in a preliminary assembling step, then puts the pin assemblies into the upper through holes and the lower through holes from a rear end face of the pin seat in a detail assembling step, and then covers the lower through holes with the covering assembly in a packaging step. The pin assemblies do not fall from the upper through holes and the lower through holes easily. The tubular lock has simplified assembling steps and lowered difficulty of assembling.

Abstract: A mobile device lock has a main body, a lock body, and a fastening set. The lock body and the fastening set are respectively mounted to the main body.

Abstract: A securing device for a portable device has a lock assembly and a cable connected to the lock assembly. The lock assembly has two locking pins, two resilient elements, a slider, and a lock mounted in a housing. When the lock is rotated by a key, the lock drives the slider and the slider pushes the locking pins to slide laterally. Thus, the lock assembly can be fastened to a casing with a lock hole and with interior space laterally reserved beside the lock hole. The securing device secures the portable device regardless of thickness of the portable device.
