A rotating cylinder applied to a lock is disclosed. The rotating cylinder is configured to guide a transmission element of the lock and defining a central axis. The rotating cylinder includes an opening, an inner wall, a first guiding structure, a second guiding structure and an engaging groove. The inner wall is communicated with the opening. The first guiding structure is formed on the inner wall and includes a first curved surface. The second guiding structure is formed on the inner wall and opposite to the first guiding structure. The second guiding structure includes a first curved surface. The engaging groove is formed between the first guiding structure and the second guiding structure. The first curved surface of the first guiding structure and the first curved surface of the second guiding structure are closer to the opening than the engaging groove. When the transmission element and the rotating cylinder of the lock are assembled, the first curved surface of the first guide structure and the first curved surface of the second guide structure guide the transmission element, so that the transmission element enters the engaging groove.
Description
technical field [0001] The invention relates to the technical field of door locks, in particular to a rotating cylinder with a guiding structure inside to facilitate easy loading of transmission parts and a lock including the rotating cylinder. Background technique [0002] A general door lock usually includes an outer handle set, an inner handle set, a latch device and a transmission member, wherein the transmission member passes through the latch device and is connected to the outer handle set and the inner handle set with its two ends respectively. Taking the knob type lock as an example, the inner handle set includes a rotating cylinder and a knob. The knob and the rotating cylinder are connected together. The parts can rotate synchronously. When the operator turns the knob of the inner handle group, it can drive the rotating cylinder to rotate together, and then drive the transmission part to rotate together, so that the lock can be switched between a locked state and a...
