A self-locking mechanical lock relying on gravity

Abstract

The invention discloses a gravity-based self-locking type mechanical lock. The mechanical lock comprises a base (1), a housing A (2),a housing B (3), a main lock hook (4), a lock block (5) and a secondary lock hook (6); the housing A (2) and the housing B (3) are symmetrically arranged on the base (1); the main lock hook (4), the lock block (5) and the secondary lock hook (6) are all mounted between the housing A (2) and the housing B (3); a first hanging hook (7) is arranged at the bottom part of the lock block (5); a second hanging hook (8) and a third hanging hook (9) are arranged at one end of the main lock hook (4); a fourth hanging hook (10) is arranged on the secondary lock hook (6); the first hanging hook (7) is matched with the second hanging hook (8); the third hanging hook (9) is matched with the fourth hanging hook (10). The gravity-based self-locking type mechanical lock can be locked and unlocked within a small travel range, and has the advantages of being simple in structure and convenient to unlock; therefore, the stability of the mechanical lock is greatly improved.

Description

technical field [0001] The invention relates to a mechanical lock, in particular to a gravity self-locking mechanical lock. Background technique [0002] The existing self-locking mechanical locks are mainly ratchet mechanisms and their deformation forms. The disadvantages are: it is difficult to realize the locking and unlocking of the locking mechanism within a small stroke range, and the unlocking of the ratchet mechanism is difficult to achieve through a simple structure; When the mechanism is locked, it mainly relies on gear self-locking and friction self-locking. The former is often used in conjunction with springs. As the use time increases, due to the hazards of mechanical fatigue and mechanical wear, the safety and stability of the ratchet mechanism are greatly improved. decline. Contents of the invention [0003] The purpose of the present invention is to provide a self-locking mechanical lock relying on gravity, which can realize locking and unlocking within a ...
