Gravity mechanical lock

Abstract

The invention provides a gravity-type mechanical lock. The gravity-type mechanical lock comprises a body, a main lock hook, a push rod, a rotating shaft and a center shaft, wherein the main lock hook is composed of a first body and a second body, the gravitational torque of the second body is larger than that of the first body, the first body is connected with the second body, the end, far away from the second body, of the first body is provided with a clamping hook, a sliding rail is arranged on the second body, a first groove is formed in the body, a fixing hole is formed in the side wall of the first groove, an installing hole is formed in the main lock hook, the center shaft penetrates through the installing hole and is matched with the fixing hole so that the main lock hook can be fixed in the first groove, the rotating shaft is fixedly connected with one end of the push rod, and the rotating shaft is clamped in the sliding rail. The gravity-type mechanical lock is simple in structure and ingenious in design, no fine workpieces exist in the gravity-type mechanical lock, firm structures are adopted for the gravity-type mechanical lock, and therefore the reliability of the gravity-type mechanical lock can also be guaranteed even after long-term use of the gravity-type mechanical lock.

Description

technical field [0001] The invention relates to a gravity type mechanical lock, which belongs to the field of locks. Background technique [0002] Existing mechanical locks use spring or friction self-locking, and these two structures will cause mechanical fatigue or mechanical wear of the lock with the increase of use time; after long-term use, the lock is prone to aging, and the aging of the equipment will seriously affect the equipment. The stability of the machine will seriously affect the safety of the equipment when used in large mechanical equipment. Therefore, providing a lock with a simple structure but strong stability has become an urgent problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a gravity mechanical lock with simple structure and ingenious design, which maintains the locked state under the action of its own gravity, has no precise workpieces as a whole, but has a stable structure and can work sta...
