Abstract

The invention relates to the field of locks, in particular to a post-variable gear and a gearbox. The post-variable gear comprises a gear body, wherein a rotating shaft or a shaft hole is arranged inthe center of the gear body. The outer circumference face of the gear body is provided with gear teeth. The post-variable gear is characterized in that at least one end of the gear body is provided with a gear boss protruding out of the end surface and a rotating support portion. The post-variable gear drives a power output assembly under driving of a power input assembly, and the power is transmitted step by step. The rotating speed of the post-variable gear is reduced, the received friction force is also greatly reduced, the service life is prolonged and the stability of transmission is improved.

Description

technical field [0001] The invention relates to the field of locks, in particular to a rear-stage transmission gear and a gearbox. Background technique [0002] At present, the quality of anti-theft doors on the market is uneven. Locks are one of the important considerations for the anti-theft safety performance of doors. Almost all locks are mechanical. The main bolt is cylindrical or square, and the stroke in the lock body is twisted by external force. block to achieve the purpose of switching locks, this type of lock body has a complex structure, many accessories, and a high failure rate, and it can no longer meet the matching requirements of the emerging smart locks. [0003] The commonly used smart lock is different from the traditional mechanical lock. It is a lock that can be more intelligent in terms of user identification, security, and management. It uses intelligent remote control to control the opening and closing of the anti-theft door. However, the existing sm...
