Problems solved by technology

However, the use of coil springs as energy storage devices inevitably has the following defects: first, the volume is too large
Second, it is difficult to achieve two-way energy storage, so it is difficult to use a spring to complete the opening and closing functions
Third, the structure is complex, the number of parts is too large, and the reliability of the mechanism is poor

Abstract

The invention discloses a vertex spring bracket for a vertex spring type operation device, comprising a platelike body. The platelike body is provided with a baffle plate, an axle hole and a fixing plate for installing and fixing the inner fixed end of an external vertex spring, and a fixed plate of the vertex spring bracket is provided with at least two clip grooves for installing the inner fixed end of the vertex spring. In the invention, the vertex spring is not needed to be adjusted, and the vertex spring can accord with the use requirement only through adjusting the installation positionof the vertex spring.

Description

technical field [0001] The invention belongs to the technical field of structural design of high-voltage electrical appliances, and in particular relates to a vortex spring bracket used in a vortex spring type operating device. Background technique [0002] The spring operating device of the traditional load switch generally adopts a helical tension spring or a compression spring. However, adopting the coil spring as the energy storage device inevitably has the following defects: first, the volume is too large. Second, it is difficult to achieve two-way energy storage, so it is difficult to use a spring to complete the opening and closing functions. Third, the structure is complicated, the number of components is too large, and the reliability of the mechanism is poor. [0003] Due to the different production batches of the scroll spring, the elastic coefficient in the free state and the specific position of the inner and outer fixed ends may be different, and it needs to ...
