Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with drawings and examples.
As shown in Figs 1-4, the utility model includes shell 6 and convex platform 8, and the welding of convex platform 8, which is mounted on inside shell 6, pushes up
The outer tip end at end, shell 6 is detachably equipped with pull ring 1 by screw thread, and the one side of shell 6 runs through along short side central axes to be provided with
Bar slot 2, shell 6 are provided with 2 one side surface of bar slot and post scale plate 3, and shell 6 is provided with the opposition side of 2 side of bar slot along short side side
Edge position is provided with second sliding slot 14, and back shroud 13 is slidably fitted in second sliding slot 14, and back shroud 13 can be from second sliding slot 14
In slide into out, can facilitate and internal structure is inspected and repaired, dismountable design reduces dismounting and maintenance difficulty, convex
8 lower end of platform is provided with first sliding groove 7, and 8 lower surface end positions of convex platform are installed by welding with spring 9 vertically, convex under in convex platform 8
Be provided with first sliding groove 7 on platform 15, and be configured with slide unit 12, can a radical for needing to increase spring 9 according to the actual situation, to reach
To the purpose for improving the whole elastic force of spring 9, increase the measurement range of tensiometer, improve the practicability of device, spring 9 it is another
End welding is mounted on lower convex platform 15, and apparatus structure is simple, easy to use, is conducive to Physical Experiment student quickly upper hand operation,
And the scale plate 3 of multi-scale precisely shows reading of standard when using different 9 radicals of spring, can facilitate student directly from scale
Reading numerical values on plate 3,15 lower surface central location of lower convex platform are installed by welding with pull rod 4,4 end integral type of pull rod welding peace vertically
Equipped with drag hook 5, slide unit 12 is slidably fitted in first sliding groove 7,15 one side central location level of lower convex platform is installed by welding with cross
Bar 10,10 ending vertical of cross bar are installed by welding with pointer 11 in 10 level of cross bar.
The bottom surface central location of shell 6, which is run through, is provided with through-hole, and through-hole diameter is greater than the outer diameter dimension of pull rod 4.Guarantee
Pull rod 4 can be stretched smoothly, and reduce the frictional force of pull rod 4 and shell 6 as far as possible, improve measurement accuracy.
It is carved with scale on scale plate 3, and scale is divided into multiple row, marks the quarter when spring 9 for using different number respectively
Degree.When being convenient for measuring object, carries out mode intuitive and easy to understand and read.
The width of convex platform 8 and lower convex platform 15 is less than the inner width of shell 6, and the structure of convex platform 8 and lower convex platform 15
It is identical with size.Guarantee the uniformity in structure, and reduce the friction of lower convex platform 15 and 6 inner wall of shell as far as possible, improves
Equipment precision.
Be provided on lower convex platform 15 with first sliding groove 7 identical on convex platform 8, cut first on convex platform 8 and lower convex platform 15
