Abstract: A lockset comprises an upper shell and a bottom plate which are fixedly connected to each other. An accommodating space is formed between the upper shell and the bottom plate. A jack is provided on the surface of the upper shell. A locking mechanism is provided within the accommodating space. The locking mechanism comprises a locking hook fitted with the jack and a control device for controlling the locking hook to move. The locking hook comprises a hook portion accessible to the underneath of the jack and a connection portion controlled by the control device. When a code is correct, the hook portion may move toward one side of the jack; and, when the code is wrong, the connection portion is limited by the control device, and the hook portion is limited underneath the jack.

Abstract: A lock comprises an upper casing and a base plate connected to each other; between the upper casing and the base plate there is an accommodation space in which the locking device is. The locking device consists of a locking hook coordinated with the receiving hole at the top surface of the upper casing and a control unit to control the movement of the locking hook. The locking hook has a hook portion which can access the bottom end of the receiving hole and a connecting portion controlled by the control unit. At the left side of the receiving hole which the hook portion faces to, there is a side plate comprising an inclined upper part and a vertical part at the lower end, and the inclined part tilt outward towards the top surface of the receiving hole for locking two zipper pull tabs together conveniently.

Abstract: A code combination lock comprises a lock body whereto a first latch hook and a second latch hook are connected, a first catch 18 fixed in the first opening direction of the case, a second catch 19 fixed in the second opening direction of the case. When locked, the first latch hook engages with the first catch and the second latch hook engages with the second catch. The code combination lock further comprises a push module, a drive module, a lock blade and a code module. The code module is arranged to push the lock blade to fix or unfix the push module such that the push module could push the drive module to lock/unlock. With this kind of code combination lock, one can lock/unlock without having to put in code repeatedly.

Abstract: A simple mechanical lock comprises a lock shell and a lock rod. The lock shell has a lock part, a lock block and a lock core inside. One end of the lock rod is a lock hook, and the other end of the lock rod is provided with a locking device. The lock core is provided with a withstanding convex block, and said lock block is provided with an unlock groove for the insertion of said withstanding convex block to lock and unlock.
