A method of manufacturing an opening and closing device

Abstract

The present invention discloses a manufacturing method of a switch breaking and closing device, pertaining to the field of emergency protection devices. Aiming at the existing problems of the need ofan additional button to control emergent switch breaking, poor stability and easiness to tripping in the conventional technology, the method provides the following technical scheme: S1 two iron fixingblocks are arranged on the side wall of a switch passage of the switch breaking and closing device, and the two iron fixing blocks are taken as one end of a circuit, wherein the two iron fixing blocks are opposite to each other, and the two iron fixing blocks do not contact with each other; S2 a central shaft is vertically arranged in the middle of the switch passage, pressure springs are arranged along the radial direction of the central shaft, one end of each pressure spring is connected with the central shaft, another end of the pressure spring is connected with one transferring plate, andwhen the central shaft rotates, the transferring plates can contact with the fixing blocks; S3 insulation rubber plates used for placing the transferring plates are fixedly arranged on the lower endsof the fixing blocks; S4 the central shaft on a central shaft frame can rotate, the central shaft frame passes through the side wall of the passage, the bottom of the central shaft is contacted withthe insulation rubber plates, and the lower end of the central shaft is connected with the bottom wall of the passage via a extension spring; S5 grinding stones are arranged on the insulation rubber plates, so that the transferring plates can contact with the grinding stones when the transferring plates rotate.

Description

technical field [0001] The invention belongs to the field of emergency protection devices, in particular to a method for manufacturing an opening and closing device Background technique [0002] Opening and closing is a device commonly used in circuit equipment. Fixed switches below 1000A in low-voltage equipment are basically equipped with opening and closing devices to perform opening and closing operations of the main switch. [0003] The opening and closing switches of switchgear manufactured in the existing market usually have the following structure, including a panel with an opening, and the emergency opening and closing device includes a fixed seat, which is installed at the opening, and has a groove connecting the inside and outside of the switch cabinet; the lever can pivot It is installed on the fixed seat, the lever has an operating end and a contact end for touching the emergency opening and closing button, wherein the lever has an operating position and a hidde...
