The utility model inclined-plane instrument includes material whereabouts case, bottom plate, dial, skewback, screw rod, fixing nut, stent
And shaft.Material whereabouts case is located at the side of bottom plate, and is integrally formed with bottom plate；Rotary shaft rack is equipped with the middle part of the bottom plate,
The shaft is rotatably installed on rotary shaft rack by bearing；The dial is fixedly mounted on bottom plate, the skewback one
End is corresponding with material whereabouts case, and cooperation is moved in the upper end of the other end and screw rod, and the middle part of the skewback is installed in shaft；It is described
Screw rod is vertically set, which sequentially passes through the threaded hole on the centre bore and stent of fixing nut, described
Fixing nut is welded on the bracket, which is mounted by means of bolts on bottom plate, and one end of the shaft, which passes through, carves
Scale is provided with needle pivot.
Specifically, one end of skewback declines as screw rod declines, and when screw rod drops to extreme lower position, skewback is protected
Water holding is put down.
By rotary screw to realize that screw rod moves up and down in fixing nut and threaded hole, rotary motion is changed into straight
Line moves.The fixing nut uses single line regular screw threads, and lead angle is less than the equivalent friction angle of screw rod, therefore fixed spiral shell
Female screw thread can meet self-locking requirement, would not also produce skewback situation unstable on screw rod.
The stent is shape of chinese word Ji stent, and cradle top is equipped with threaded hole, while uses spot welding on the top in threaded hole
Mode fixing nut is fixed on stent.
The dial of the utility model inclined-plane instrument is fixedly mounted on base, and the needle pivot of dial turns with shaft
It is dynamic.When screw rod is moved up and down so that shaft rotates, the needle shaft on dial also rotates therewith, finally so that skewback tilts
Dial needle shaft of the angle in dial, which is shown, will be apparent that.
The utility model has the advantages that：Slow rotary screw causes screw rod is stablized to rise or fall, and then promotes skewback
Slowly rise or fall, clearly illustrated finally by the needle pivot in dial（Measure）Friction coefficient.Using accurate rotation
Turn screw rod, accurately measure friction coefficient, reduce the measurement error caused by hand tremor or other extraneous factors, improve and rub
Wipe the accuracy of coefficient determination.

Embodiment
The technology contents of the utility model are further described with reference to instantiation, the advantages of the utility model and spy
Point will be with description and it is apparent.But these examples are only exemplary, and the scope of the utility model is not formed and is appointed
What is limited.It will be understood by those skilled in the art that can be to this reality under the spirit and scope without departing from the utility model
Modified or replaced with the details and form of new technique scheme, but these modifications and replacement each fall within the guarantor of the utility model
In the range of shield.
From fig. 1, it can be seen that the utility model inclined-plane instrument includes material whereabouts case（1）, bottom plate（2）, dial（3）, skewback
（4）, screw rod（5）, fixing nut（6）, stent（7）And shaft（8）；Material whereabouts case（1）Positioned at bottom plate（2）Side,
And and bottom plate（2）It is integrally formed, the bottom plate（2）Middle part is equipped with rotary shaft rack, the shaft（8）It is rotatably installed in by bearing
On bracing strut, the dial（3）It is fixedly mounted on bottom plate（2）On, the skewback（4）One end and material whereabouts case（1）It is right
Should, the other end and screw rod（5）Upper end move cooperation, the skewback（4）Middle part be installed on shaft（8）On；The screw rod（5）
Vertically set, the screw rod（5）Lower end sequentially passes through fixing nut（6）Centre bore and stent（7）On threaded hole
（71）, the fixing nut（6）It is welded on the stent（7）On, the stent（7）It is mounted by means of bolts on bottom plate（2）
On, one end of the shaft passes through dial（3）Needle pivot is installed（31）.
From Fig. 2 a, 2b and Fig. 3, skewback（4）One end and material whereabouts case（1）It is corresponding, skewback（4）It is another
One end and screw rod（5）Upper end move cooperation, skewback（4）Middle part and shaft（8）It is fixedly connected, is thusly-formed a kind of similar lift up
The structure of seesaw.Work as rotary screw（5）, screw rod（5）Expose fixing nut（6）Height with change, skewback is under material
Fall the angle of inclination at case, dial and the point of screw rod three also therewith to change, when screw rod is dropped under fixing nut completely, inclined-plane
The other end of plate is also completely supported on fixing nut, and skewback holding at this time is horizontal, shaft rotates therewith, with shaft
The needle pivot being fixedly connected also rotates, and the angle of inclination of dial is shown as 0o at this time.
When this inclined-plane instrument is specifically used：By simple grain material（Corn, mung bean）It is placed on skewback（4）On, by rotating spiral shell
Bar（5）, screw rod（5）Rise or fall therewith, so make skewback（4）Certain inclination angle is presented, can understand in dial
Show angle of inclination, corresponding friction coefficient is then calculated by formula.
Pass through multiple adjustment screw（5）The height rise, declined makes skewback（4）Tilt at an angle, ensure material
It will not be slided in this angle.Then screw rod is gradually rotated again（5）, when slip takes place in material, observe scale
Disk（3）Upper needle pivot（31）Signified reading, is angle of frictionValue, according to formula：Calculate simple grain material
Friction coefficient.Multigroup experiment is finally repeated, finally acquired results are averaged.
With stent standing screw, and then ensure the stability of test process, prevent screw rod from tilting, so that measurement result
Accuracy.Screw rod slowly is turned, screw rod moves up or down, and skewback is withstood in the upper end of screw rod so that skewback is slow
Tilt, for each revolution, skewback is tilted a certain angle screw rod.Subsequent inclined angle is by dial needle axis in dial
Upper display.All it is in the past to use the side for manually slowly lifting skewback with the confficient of static friction of inclined-plane instrument measurement material,
When minute movement occurs for material, the reading of dial is recorded, shake or other extraneous factors that so can be due to human hand be led
Cause measurement result inaccurate.The utility model makes skewback slowly rise by the rotation of screw rod, and it is dry to overcome some external worlds
Factor is disturbed, utilizes formulaFriction coefficient is calculated, whereinThe number of degrees being directed toward for dial needle.
