Electric arc is very big during contact, this is easy for the abrasion for causing two contacts；And when multiple breakers and together with, and using single
When one handle controls, its synchronism closed a floodgate cannot guarantee that；It although can be with rapid closing in addition, also there is one kind on the market
Breaker, but its structure is more complicated, generally requires setting copper pipe and several parts rivet together to place parts
Abjection, production, assembling are all cumbersome.
Invention content
In view of the deficiency of background technology, the technical problem to be solved by the utility model is to provide one kind can realize quickly
It closes a floodgate, and simplifies its structure so that it is produced with assembling more convenient miniature circuit breaker energy accumulation handle mechanism
For this purpose, the utility model is realized using following scheme：
Miniature circuit breaker energy accumulation handle mechanism, including handle body, the handle body is pulled arm and is turned by integrally formed
Moving part forms, it is characterised in that：The endoporus of the rotating member is fixed with axle sleeve, and the end face outside of the rotating member is equipped with band circle
The annular protrusion of all notches, energy storage torsional spring and energy storage tripping part are equipped in the space that the annular protrusion crosses, and the energy storage is jumped
Fastener is rotatably set on sleeve outer circle, and the excircle of the energy storage tripping part is locally equipped with clamping portion, and the clamping portion is located at circle
In all notches, the energy storage torsional spring is movably set in sleeve outer circle, and the left end of the energy storage torsional spring is against the left side of circumferential notch
Wall, the left side wall of circumferential notch limit the left end of energy storage torsional spring equipped with limited block, and the right end of the energy storage torsional spring is mounted in
In clamping portion, under the action of energy storage torsional spring so that the right side wall of circumferential notch is pressed in clamping portion, on the left of circumferential notch
Wall position, the outer circle of the annular protrusion are equipped with expression lobes, and the lower section of the rotating member is equipped with strip, the left end of the strip
Rotatable setting, right end are equipped with the discount fastened with clamping portion, and when rotating member rotates counterclockwise, the expression lobes are squeezed downwards
Pressure strip simultaneously drives its rotation so that the discount on strip is detached from clamping portion.
Preferably, the clamping portion is equipped with driving member connecting hole.Allow handle mechanism easily with breaker
Interior transmission mechanism connection.
Using above-mentioned technical proposal, the advantages of the utility model, is：1st, when pulling arm, power can be first stored in storage
In energy torsional spring, the power disposably stored by energy storage torsional spring again later is transferred to transmission mechanism, realizes the fast of dynamic and static contact
Speed is closed, and effectively reduces abrasion during the two contact, meanwhile, the energy accumulation handle of this structure may be multiple and together with
Breaker closing when sufficiently large power is provided, ensure the synchronism closed a floodgate between breaker；2nd, the setting of limited block ensures storage
Energy torsional spring will not be deviate from from the axle sleeve on rotating member, and energy storage torsional spring presses energy storage tripping part, also ensures energy storage tripping part
It will not deviate from from the axle sleeve on rotating member, pass through the riveting copper between rotating member and energy storage tripping part instead of conventional handle mechanism
Pipe ensures structure that energy storage torsional spring and energy storage tripping part are not fallen out, effectively reduces the parts of handle mechanism and assembling work
Sequence so that the production and assembling of handle mechanism are all more convenient, quick.
Description of the drawings
The utility model has drawings described below：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of energy storage tripping part.
Specific embodiment
As shown in the figure, miniature circuit breaker energy accumulation handle mechanism disclosed in the utility model, including handle body, handle body
