Lock linkage toggle shaft

Abstract

A linkage shifting block shaft for a lock comprises an inner shifting block, an outer shifting block, and inner connection rod and an outer connection rod. A first blind hole is formed in the inner side of the inner shifting head, a first through hole is further formed in the inner shifting head, wherein the first through hole is communicated with the first blind hole and can drive the inner connection rod to rotate, and the inner connection rod is in linkage with the first through hole and is matched with the shape of the first through hole. A boss matched with the first blind hole is arranged on the inner side of the outer shifting head, a second blind hole consistent with the first through hole in shape is formed in the inner side of the outer shifting head, a spring blind hole communicated with the second blind hole is formed in the tail of the second blind hole, a third blind hole capable of driving the outer connection rod to rotate is formed in the outer side of the outer shifting head, and a separation and reunion spring is arranged in the spring blind hole. The linkage shifting block shaft for the lock is simple and stable in structure, low in cost, capable of being universally applied to the field of various mechanical locks. A self-destruction structure is provided, once an outer panel is disassembled by force, the lock cannot be opened, and therefore the linkage shifting block shaft for the lock eliminates the potential safety hazards that the lock can be directly opened after the outer panel is disassembled, and use is safer.

Description

(1) Technical field [0001] The invention relates to the technical field of mechanical locks, in particular to an electronic lock and a double-quick unlocking body. (2) Background technology [0002] At present, in the field of electronic lock technology and the field of mechanical combination locks, the clutch mechanism is set in the lock body and driven by a motor or electromagnet, and the clutch mechanism is set on the outer panel through a structure such as a motor or electromagnet drive and a mechanical combination drive. The former has a high level of security. The disadvantage is that the structure is complex, the cost is high, the lock body is special and the fault is high, and the latter has the advantages of integrated design of the panel and the lock body adopts ordinary double fast pass to open the lock body. The cost is low, the structure is stable and there are few faults. . (3) Contents of the invention [0003] In order to solve the above disadvantages, the...
