Rotation operation structure

Abstract

A rotation operation structure comprises a rotating shaft, and is characterized in that the rotating shaft (1) can drive a reversing plate (3) and a transmission plate (4) to move together through a reversing clutch mechanism (2), the reversing plate (3) is connected with a reversing special-shaped double-torsion spring (5), a bearing (10) is installed on the transmission plate (4) and is connected with an operation torsion spring (6), and the reversing clutch mechanism (2) enables the reversing plate (3) and the transmission plate (4) to be separated from the rotating shaft (1) in the processthat the rotating shaft (1) drives the reversing plate (3) and the transmission plate (4) to move together. According to the present invention, the rotating operation structure can ensure that the isolating switch can be reliably switched on and off even if the action of an operator is delayed ,after the rotating shaft passes through a stress dead point and in the rotating switching-on or switching-off process of the rotating shaft, and meanwhile, when the rotating shaft rotates to the bottom, the automatic reversing is achieved through the reversing clutch mechanism for reverse operation.

Description

technical field [0001] The invention belongs to the technical field of switches, and in particular relates to a rotating operation structure. Background technique [0002] The word switch is interpreted as on and off. It refers to a component that can open a circuit, interrupt the current flow, or cause it to flow to other circuits. The most common switches are human-operated electromechanical devices that have one or more contacts. The "closed" of the contact means that the contact is conducting and allows the current to flow; the "open" of the switch means that the contact is not conducting and forms an open circuit, and the current is not allowed to flow. The development history of the switch has developed from the original switch that requires manual operation to the intelligent switch used in various large-scale electrical control equipment. The function of the switch is more and more, and the safety is getting higher and higher. A rotary switch is a common switch th...

Problems solved by technology

[0004] The purpose of the present invention is to provide a rotating operation structure for the technical defect of the above-mentioned existing rotating operation structure of the electric switch, which is easy to make the combined switch of the movable contact not in place due to the delay of the operation action caused by the operator during the closing process. It can ensure that the isolating switch can be reliably closed even if the operator's action is delayed after the rotating shaft passes the dead point during the closing process of the rotating shaft. It is not affected by the operating speed of the operator and has nothing to do with manual operation.
