A kind of thermorelay fixed structures of the double gold of compensation, including pedestal, double gold compensating plate and axle, on described pedestal
It is provided with fixed seat, the upper and lower of described fixed seat is provided with the first locating piece separated by a distance and the second locating piece, described
Form breach between a positioning block and the second locating piece, in described first locating piece and the second locating piece, be provided be coaxially disposed logical
Hole, the side of each described through hole is equipped with and snaps in mouth, and described double gold compensating plates are fixedly connected with the middle part of axle, one end of described axle
Pushed in the through hole of the first locating piece by snapping in mouth, the other end is located at and snaps in, by another, the through hole that mouth pushes the second locating piece
Interior, the middle part of described axle passes through breach, and described double gold compensating plate is located in breach and can be rotated along through hole by axle.
The side of described first locating piece and the second locating piece is provided with the opening communicating with through hole.
Described first locating piece and the second locating piece are formed with fixed seat integrally connected.
Described first locating piece and the second locating piece and fixed seat integrated injection molding.
The through hole lower end of described second locating piece is provided with baffle plate, and the lower end of described axle contacts on baffle plate.
Described double gold compensating plate is provided with pad, and described pad is mutually welded with the outside of axle.
Described first locating piece and the second locating piece are cylinder, and the described area snapping in mouth is less than half face of cylinder
Long-pending.
The method have the advantages that because this thermorelay is with compensating the fixed structure of double gold using extruding buckle
The fixing mode of assembling, structure is simple, and cost-effective, processing request is low, and assembly process is simple, saves the operating time, and avoids
Abjection phenomenon in rotary course in compensating plate.
