Abstract

The present invention relates to a spring operating mechanism. The spring operating mechanism includes a rack and a manual operating shaft rotationally assembled on the rack; the manual operating shaft is coaxially provided with a reset torsional spring; a shifting component which is clamped between two force applying arms of the reset torsional spring is fixed to the manual operating shaft; the shifting component supports the two force applying arms apart so as to realize pre-compressed deformation amount; and the rack is provided with a fixed stopping component which is in stopping fit with the inner sides of the two force applying arms when the manual operating shaft is in a reset state. According to the spring operating mechanism of the invention, in a process in which the manual operating shaft is reset from a switching-off position or a switching-on position, the reset torsional spring can continuously apply a resetting force to the manual operating shaft; after the manual operating shaft is reset, the reset torsional spring can still apply the resetting force; and therefore, reset accuracy can be improved, a reset position can be ensured, and security potential safety hazards can be effectively eliminated.

Description

technical field [0001] The invention relates to a spring operating mechanism. Background technique [0002] In medium and low voltage vacuum circuit breakers and intelligent switches, the spring operating mechanism still plays a pivotal role. The electric functional performance of the spring operating mechanism is often the top priority of vacuum circuit breaker and smart switch users, and the safety and reliability of its manual function also plays a decisive role in its stable performance. [0003] The Chinese patent with application number 201320590273.7, authorization announcement number CN 203787343 U, and authorization announcement date 2014.08.20 discloses a manual spring operating mechanism, including a frame and an energy storage mechanism assembled on it, and a manual opening and closing mechanism. The manual opening and closing mechanism includes a closing swing arm for controlling the action of the closing detent, an opening swing arm for controlling the action ...
