Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.
As shown in figure 1, a kind of elevator machine formula weighing device, including microswitch 1, limiting and protecting device 2 and installation bottom
Seat 4, the limiting and protecting device 2 includes the position limitation protection plate 9 and guide rod 5 being fixedly connected, and guide rod 5 is provided with screw thread；Institute
Mounting base 10 and guide way 7 that mounting seat 4 includes being fixedly connected are stated, guide way 7 is hollow structure；Also include spring 3, institute
Guide rod 5 is stated to sequentially pass through spring 3 and guide way 7 and lock by fine-tuning nut 6；The microswitch 1 is fixed on spacing guarantor
The top of backplate 10, the contact 8 of microswitch 1 is located at the top of microswitch 1.The microswitch 1 and limiting and protecting device 2 with
The quantity of guide way 7 is identical.The vertical plate of the bottom of position limitation protection plate 9 is fitted with the back side of mounting base.The material of spring 3
For carbon spring steel.The spring 3 is located between guide way 7 and position limitation protection plate 9.
As shown in Fig. 2 elevator machine formula weighing device of the present utility model is by three groups of microswitches, position limitation protection dress
Put, spring and a set of mounting seat component combination are formed, limiting and protecting device is welded by position limitation protection plate and guide rod, pacify
