Summary of the invention
The utility model overcomes the deficiency that prior art exists, and provides a kind of and can regulate repeatedly, the bidirectional modulation overload characteristic, and adjustment process is stable, promotes bimetal leaf rigidity, makes the novel thrermostatic bimetal-plate overlond trip mechanism of its dropout process stabilization.
Realize above-mentioned purpose, the utility model adopts following technical scheme, a kind of thrermostatic bimetal-plate overlond trip mechanism, it is characterized in that: include housing, bimetal leaf, regulating part, strutting piece, release lever and keeper, wherein keeper and strutting piece are arranged on two positions of housing, bimetal leaf one end is arranged on the keeper, the other end is arranged on the strutting piece, described release lever one end is hung on the middle part of bimetal leaf, described regulating part is arranged on the housing, the one end is connected on the strutting piece, moves the swing that drives bimetal leaf thereby regulating part can drive strutting piece on housing.
Of the present utility model further the setting again is: described keeper is fixed on the housing by two axles to be formed, be respectively arranged with seamed edge on two axles, the seamed edge of two axles is oppositely arranged the formation clamp area, and the dual-side of bimetal leaf bending direction is conflicted on the seamed edge of two axles.
Of the present utility model further the setting again is: described strutting piece is provided with standing groove or putting hole, and the dual-side of standing groove or putting hole symmetry also is a seamed edge, and the dual-side of bimetal leaf bending direction is conflicted on the seamed edge of standing groove or putting hole.
Last further setting the of the present utility model is: described strutting piece includes guiding slippage limit, placement section and adjusting portion, described housing is provided with gathering sill, the guiding slippage limit of strutting piece places housing to be provided with gathering sill, described standing groove or putting hole are arranged on the placement section of strutting piece, described regulating part is a bolt, its rotation is arranged on the housing, the screw top of bolt is screwed on the adjusting portion of strutting piece, thereby the rotation of bolt can drive the gathering sill slippage drive bimetal leaf swing of strutting piece along housing.
By adopting above-mentioned scheme, the utility model reaches following beneficial effect:
The change in location process stabilization of bimetal leaf when one, regulating bimetal leaf by the adjuster of design specialized is feasible, the two-way adjusting repeatedly of this design simultaneously almost do not have influence to overload performance.
Two, be designed to the spacing mid point in two ends and improved the rigidity of bimetal leaf, make the heating dropout process stabilization of bimetal leaf as the structure of working point.Avoided the bimetal leaf change in location that causes because of spot welding stress in the former design simultaneously.
Three, bimetal leaf is designed to that two ends are spacing just to make that the change in location of bonding conductor is very little, has weakened the flexible requirement to bonding conductor.
Below in conjunction with accompanying drawing the utility model is further described.
