The end of connection ring 166 is arranged in the mounting hole of sleeve 1644, and can freely be rotated in mounting hole；The company of hanging over of suspension hook 162
Connect on ring 166.
The assembling process of connecting portion 160 is as follows：First sleeve 1644 is sheathed in connecting shaft 1642, and baffle plate 1646 is filled
Put the end of connecting shaft 1642；Then the end of connecting tube is installed in the mounting hole of sleeve 1644；Finally suspension ring are hung over
In connection ring 166.
Such as Fig. 2, cast dynamometer 100 also includes end cap 180, and end cap 180 includes circular slab 184 and columned installation portion
182.The external peripheral surface of circular slab 184 is provided with multiple groove (not shown)s, and installation portion 182 is provided with external screw thread, peace
The one end in dress portion 182 is connected with the end face of circular slab 184.
Such as Fig. 1 and Fig. 2, the assembling process of cast dynamometer 100 is as follows：First the connecting portion 160 of spring and end cap 180 is connected
Connect, connecting portion 160 is threadedly coupled with outer tube 110；Then inner tube 150 is encased in outer tube 110, and spring is passed through inner tube
150, the free end of spring is connected with connecting portion 160, connecting portion 160 is connected with inner tube 150, and by poke rod 130 with it is interior
Pipe 150 is connected, and poke rod 130 is located in bar hole 113；Keeper 140 is finally mounted in the bar hole of outer tube 110
In 113, and cause keeper 140 relative to poke rod 130 closer to the free end of spring.
Such as Fig. 1 and 2, after the completion of assembling, cast dynamometer 100 is returned to zero.During zeroing, by the indicateing arm on keeper 140
Zero graduation line on will alignment scale layer 170, screw 190 is unclamped, rotary end cover 180, end cap 180 drives spring and inner tube
150 motions, inner tube 150 drives poke rod 130 to move, until poke rod 130 is abutted with keeper 140.After the completion of zeroing, by spiral shell
Nail 190 is tightened so that the end of screw 190 is abutted with the installation portion 182 of end cap 180.
The operation principle of cast dynamometer 100 is as follows：When measuring weight, weight is hung on suspension ring, spring elongation becomes
Shape, inner tube 150 is moved relative to outer tube 110, and inner tube 150 drives poke rod 130 to move, and poke rod 130 promotes keeper 140 to transport
It is dynamic.After the position of weight is stable, the position of keeper 140 is also accordingly fixed.Now, weight is removed, spring and inner tube 150 are multiple
Position, because keeper 140 is simply connected with outer tube 110, is not connected in inner tube 150 and poke rod 130, therefore keeper 140
Rest on position just now.So as to easily record measurement data.Keeper 140 can be back into by record after finishing
The position of zero groove.
Further, since there is provided keeper 140, cast dynamometer 100 also has the function that peak value is positioned.Specifically,
When repeatedly being measured to same weight or different weight, only when after measurement data once be more than previous measurement number
According to when, keeper 140 just can be moved accordingly.Therefore the data that cast dynamometer 100 finally gives are the maximum of measurement data.
Because connecting portion 160 is provided with rotating connector 164, when weight is hung on suspension ring, sleeve 1644 can be relative to
Connecting shaft 1642 is rotated by 360 °.The angled not dead phenomenon when measuring and weighing so is avoided, so as to avoid measurement
Data it is inaccurate.
It should be noted that the present embodiment is preferred embodiment, in other embodiments, connecting portion can also be not provided with
160, now, weight is directly connected with the free end of spring；Or, keeper 140 can also be other structures, such as keeper
140 be integrally formed, and neck is provided with keeper 140, and keeper 140 is stuck in by neck on the tube wall of outer tube 110；Or
Person can also be not provided with inner tube 150, now, and poke rod 130 is directly connected with the free end of spring；Or end can also be not provided with
Lid 180, end of the spring directly with outer tube 110 is connected.These changes do not interfere with the realization of technical solutions of the utility model,
And preferably technique effect can be reached.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for
For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former
Within then, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
