Summary of the invention:
The present invention is in order to solve technical matterss such as existing in prior technology instrument volume is big, measuring error is big, but provides little, highly sensitive, the easy to adjust gamut of a kind of volume to set the temperature indicating controller for use in transformer of temperature control point.
Technical solution of the present invention is: a kind of temperature indicating controller for use in transformer, housing 1 is arranged, base 2 is set in housing 1, be fixed with flexible member 3 on the base 2, be connected to sensing catheter 4 with flexible member 3, the other end of sensing catheter 4 is connected to the temperature sensing part 5 that places outside the housing 1; Also be connected to catch bar 6 with flexible member 3, catch bar 6 drives movement 7, be connected to the pointer 9 that places on the panel board 8 with movement 7, described flexible member 3 and the catch bar 6 that joins with it vertically are provided with, between catch bar 6 and movement 7, be connected to pull bar 10, also be connected to horizontal lever 11 with catch bar 6; On the base 2 below the horizontal lever 11, be fixed with cam 12, be connected on the cam 12 and the laterally fixing extension spring 13 of lever 11 fulcrums one end, also be connected to and the fixing cam linkages 14 of horizontal lever 11 other ends; Being provided with on base 2 with cam 12 is the annular groove 15 at center, and annular groove 15 is provided with the switch module 16 that can touch mutually with cam 12.
Be equipped with the switch module 16 that can touch mutually with cam 12 in the three sections circular arc settings in 15 fens of described annular groove, every section circular arc.
Be connected to external connection terminal box 17 with housing 1, external connection terminal box 17 is fixed with connection terminal 18.
Be provided with between described switch module 16 and the annular groove 15 and regulate axle sleeve 19.
The present invention is flexible member to be reached the catch bar that joins with it vertically be provided with the difference of prior art, can drive movement by a connecting rod, can reduce the systematic error on the mechanical drive, improves accuracy of instrument, makes the temperature indication accurately; Touch the switch module that in annular groove, is provided with by cam with movement rotation synchronously, can realize stirring to a plurality of switches, simple in structure, easy for installation, but gamut is set the temperature control point arbitrarily, whole instrument volume is reduced, reduce the instrument housing expense, the switch more than four also can be set as required, in instrument to adapt to the control needs of different temperature points; The user can regulate temperature control point as required voluntarily, saves the general expenses and the man-hour that need return-to-factory to regulate, has reduced the product maintenance cost; Switch module is set in the annular groove by regulating shaft, need not screw, makes the adjusting of temperature control point convenient.
