Abstract

The invention discloses a brake mechanism for a coil spring-type operation device, which comprises an output board, two brake engines and a support spring for providing reset elastic force for the engines; the output board comprises a board body, and the board body comprises a shaft hole, a baffle, two installation holes for installing the engines and two limit holes for limiting the rotating angles of the engines; all the limit holes are arranged above the installation holes; the two engines are symmetrically arranged on both sides of the shaft hole, the front side end of each engine is provided with two cylinders which protrude forwards, an upper cylinder serves as a limit column and is arranged in a corresponding limit hole on the output board, and a lower cylinder serves as an installation column and is arranged in an installation holed of the output board; and both ends of the support spring form a V shape, and are respectively propped against the limit columns of the two engines. The brake mechanism for the coil spring-type operation device has the advantages of more simplified structure, fewer parts, and better reliability and stability.

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 braking mechanism used in a scroll spring 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] Patent document CN2423648Y discloses a planar scroll spring energy storage and release mechanism. The whole device is composed of a first chamber and a second chamber composed of three curved plates. There a...
