Magnetic motive force bouncing-closing rotating base

Abstract

The invention discloses a magnetic motive force bouncing-closing rotating base. The magnetic motive force bouncing-closing rotating base comprises a round bottom plate, a base, a bouncing-closing swinging magnetic frame and an outer frame, the base is arranged on the round bottom plate and is of a cap structure, a wire rack is arranged in a cavity in the bottom of the base, a coil is wound aroundthe wire rack and connected with a current sensor used for sensing the condition of current sudden changes, a first groove hole which is upward is embedded into the top of the base, protruding parts are arranged on the two sides of the top of the base respectively, the bouncing-closing swinging magnetic frame comprises a vertical pin, a magnetic piece and a first umbrella frame, multiple blades are arranged on the periphery of the first umbrella frame at intervals, the top of the first umbrella frame and the magnetic piece fixedly penetrate through the vertical pin from top to bottom, a seconddownward groove hole is formed in the top of the outer frame, and the upper end of the vertical pin is movably arranged in the second groove hole. According to the magnetic motive force bouncing-closing rotating base, by rotating the red first umbrella frame plate, the effect that an alarm is made through a red flag is realized, and the magnetic motive force bouncing-closing rotating base is simple in structural design, low in cost and good in alarm effect.

Description

technical field [0001] The invention belongs to the technical field of indicators, and relates to a magnetic power snap-fit ​​rotating seat. Background technique [0002] The distribution line fault indicator is a fault information indicating device used to detect and indicate whether the fault circuit of the user's power line flows through here. The magnetic field and electric field changes around the power line, and the control circuit inside the power line fault indicator monitors these changes, automatically judges whether the fault circuit flows through here, and then outputs an alarm signal to drive the display part to work, and the alarm flashes the red indicator light, So as to achieve the purpose of indicating the failure of the faulty line. [0003] However, red indicator lights are generally used now, and the red indicator lights are controlled to flash at intervals of a certain period of time. In this way, not only a dedicated red indicator light is provided, bu...
