Title:
PINHOLE TYPE LOCK BODY STRUCTURE AND TRANSFORMABLE KEY STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/125687
Kind Code:
A1
Abstract:
The present invention relates to the technical field of safeguard devices. Disclosed are a pinhole type lock body structure and a transformable key structure. The lock body structure is unlocked using a pluggable structure by means of an outer keyhole and an inner keyhole; an unlocking key variable of the lock body is changed from an internal structure in a key hole into a key pin entry amount; only when a key pin pushes a code pushing block to move by a specific distance, can the contact surface of a locking block and the code pushing block coincide with the communication surface of the outer keyhole and the inner keyhole, thereby implementing unlocking. Therefore, the lock body structure has higher the safety and reliability. The key structure can provide multiple unlocking key pin layout solutions on one key structure by combining variable dial and key pin structures, and only a particular layout solution can unlock a corresponding door leaf. Therefore, the lock body cannot be directly unlocked when a user not being an owner holds the key. The key structure enhances the protection performance of a mechanical lock and enhances the reliability of the mechanical lock. Therefore, the present invention is suitable for popularization.
