Abstract: An improved structure of an electronic lock includes an outside-door assembly, a lock middle, an inside-door assembly, and a latch. The outside-door assembly is mounted to an outer side of a door panel. The lock middle is connected to the outside-door assembly. The inside-door assembly is connected to the lock middle and is mounted to an inner side of the door panel. The latch is connected to the latch coupler. With a code entered, an electrically-driven valve of the lock middle causes a guide block and a projection block to extend outward to have an outside handle and the lock middle to synchronously operate for opening the door. Alternatively, a key may be used to open the door. If such a code and a key are both not available, the outside handle and the lock middle do not synchronously operate.

Abstract: A pushbutton type easy-code-change handle lock includes an outdoor assembly, a latch bolt arresting member, a latch bolt, and an indoor assembly. The outdoor assembly is mounted to an outside surface of a door panel and is coupled to an end of the latch bolt arresting member. The latch bolt arresting member drives the latch bolt to move. The indoor assembly is coupled to an opposite end of the latch bolt arresting member. The outdoor assembly includes a mechanical combination lock. When a user enters a correct combination of codes, the mechanical combination lock is operated and the external door handle and the latch bolt are operated synchronously to open the door; and if no code is provided, a key may be used to open the door; and if both codes and key are not provided, the external door handle and the latch bolt cannot be operated synchronously.
