In order to ensure the seriality powered, the overload-alarm non-tripping device of chopper is widely adopted.It is arranged on disconnected
Road device load end, directly gathers A phase, B phase, C phase operating current signal, when load current is specified more than the chopper of certain multiple
During electric current (In), continue in the regular hour, chopper can provide an alarm actuating contact signal, remind user load super negative
Lotus, and do not execute dropout.
Utility model content
The purpose of this utility model is it is simply that report to provide a kind of HM60-100 of chopper with new structure to transship
Alert not trip gear.
To achieve these goals, this utility model employs technical scheme below：A kind of HM60-100 mistake of chopper
Carry alarm non-tripping device, for acquisition testing three-phase operating current signal, realize alarm non-tripping, including pedestal, draw bar,
Bimetal leaf assembly, microswitch and reduction torsion spring；Draw bar activity is erected on pedestal, bimetal leaf assembly totally three groups uniform
Interval setting is simultaneously connected with draw bar transmission respectively, and microswitch is arranged on the right-hand member of pedestal, reduction torsion spring be connected to pedestal and
The elastic force that draw bar resets is provided between draw bar；When chopper has overcurrent, bimetal leaf is heated and produces bending, drives
Draw bar rotates counterclockwise, and then triggers the contact of microswitch, so that contact is converted to normally closed by normally opened, provides the user with one
Overload-alarm contact signal.
Described pedestal includes two supports, is connected with the framework for installing draw bar in two frame upper, in framework
Right-hand member is provided with microswitch mounting seat, and described microswitch is arranged in this microswitch mounting seat.
Described draw bar includes drawing bar body, is interval with the U-lag of three upward openings in traction bar body,
The right-hand member of traction bar body is provided with the projection of the contact for triggering microswitch.
Described bimetal leaf assembly includes heater element, bimetal leaf and adjusting screw, bimetal leaf and heater element
Bottom is connected and stretches out upward, and adjusting screw is connected to the upper end of bimetal leaf U-lag cutting ferrule corresponding on draw bar
It is connected.
Described draw bar is provided with locating piece, and this locating piece can contact the return state to draw bar that is connected with pedestal to be carried out
Positioning.
The HM60-100 overload-alarm non-tripping device of chopper of the present utility model due to employing above technical scheme,
There is following significant advantage and feature：
1), structure is simply it is easy to assemble；
2), directly drive draw bar to rotate by bimetal leaf heated bending, and then trigger microswitch, output is reported to the police and touched
Point signal.
3), improve the seriality of power supply.

Specific embodiment
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, referring to Fig. 2, Fig. 3, Fig. 4, the HM60-100 overload-alarm of chopper of the present utility model does not take off for cooperation
Buckle device, including pedestal 1, draw bar 2, bimetal leaf assembly 3, microswitch 4 and reduction torsion spring 5；Draw bar activity is erected at
On pedestal, totally three groups of uniform intervals are arranged and are connected with draw bar transmission respectively bimetal leaf assembly, and microswitch is arranged on base
The right-hand member of frame, reduction torsion spring is connected to the elastic force providing draw bar to reset between pedestal and draw bar；When chopper has overload electricity
During stream, bimetal leaf is heated and produces bending, drives draw bar to rotate counterclockwise, and then triggers the contact of microswitch, makes contact
Be converted to normally closed by normally opened, provide the user with an overload-alarm contact signal.
Referring to Fig. 2, the pedestal 1 in this utility model includes two supports 11, is connected with use in two frame upper for cooperation
In the framework 12 installing draw bar, it is provided with microswitch mounting seat 13 in framework right-hand member, microswitch is arranged on this microswitch
In mounting seat.
Referring to Fig. 3, the draw bar 2 in this utility model includes drawing bar body 21 for cooperation, is spaced in traction bar body
It is provided with the U-lag 22 of three upward openings, be provided with the projection of the contact for triggering microswitch in the right-hand member of traction bar body
23.
Referring to Fig. 4, the bimetal leaf assembly 3 in this utility model includes heater element 31, bimetal leaf 32 and adjusts for cooperation
Section screw 33, bimetal leaf is connected with the bottom of heater element and stretches out upward, and adjusting screw is connected to the upper of bimetal leaf
