Abstract

Disclosed is an elastic energy storage transmission mechanism. The elastic energy storage transmission mechanism is characterized by comprising a driving rotary plate (102); an energy storage spring (104) is arranged on a rotary shaft (102a) of the driving rotary plate (102) in a sleeving manner; the driving rotary plate (102) rotates to drive the energy storage spring (104) to store energy; a driven plate (106) is also mounted on the rotary shaft (102a) of the driving rotary plate (102); and the driven plate (106) can be driven to rotate in the energy releasing process of the energy storage spring (104). Elastic part transmission is additionally added on a transmission chain, and the elastic part can perform mechanical type energy storage, so that the problem of potential safety hazard caused by the fact that a small-sized circuit breaker contact stops in a middle state when the rigid-transmission electrical small-sized circuit breaker suffers from an abnormal power failure condition in the switch-on action executing process in the existing market can be solved.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, and specifically relates to an elastic energy storage transmission mechanism, which improves the safety of a circuit breaker. Background technique [0002] The opening and closing actions of traditional miniature circuit breakers require manual operations. With the development of smart grid, there is an urgent need for small circuit breaker products that can reliably realize automatic opening and closing. Therefore, small circuit breakers assembled with electric operating devices have appeared on the market. By sending instructions to the electric operating device, the small circuit breaker can be driven to open and close automatically without manual operation, which effectively saves manpower and material resources. Applications are increasingly widespread. However, for such products that are common in the existing market, the internal transmission mechanism component...
