Abstract
The utility model relates to a friction angle measurement demonstration instrument, which comprises a hinged overturning device, a push rod device and an angle calibrated scale, wherein the hinged overturning device comprises a base provided with a sliding groove, and an overturning support hinged with the base; the push rod device comprises a rotating screw rod installed in the sliding groove, a hinge nut sliding block which is matched with the rotating screw rod and can slide in the sliding groove, and a push rod which is hinged with the hinge nut sliding block on one end and hinged with the overturning support on the other end; the angle calibrated scale is fixed to the side surface of the base, and is used for measuring the overturning angle of the overturning support; and an A measured member is arranged on the overturning support, and a B measured member is arranged on the A measured member. The friction angle measurement demonstration instrument adjusts the overturning angle of the overturning support through transmission of the screw rod and the nut and the pushing of the push rod, further can measure the friction angle between the two measured members by observing the reading of the calibrated scale about the overturning angle when the B measured member slides from the A measured member.
Description
Technical field
The utility model relates to a kind of demonstration instrument for teaching, particularly relates to a kind of demonstration instrument for teaching of measuring angle of friction.
Background technology
When object can at the uniform velocity glide just from coarse inclined-plane, the inclination angle on inclined-plane is called angle of friction, just can determine the dynamic friction factor between object and inclined-plane if record this angle.
About the knowledge point of angle of friction often occurs in University Engineering mechanics, some teacher has also made some models, teaching aid is demonstrated on classroom, but effect bad, main cause is variation that cannot fine adjustments inclination angle of inclined plane, and and the angle of inclination that is not easy to read inclined-plane.
Summary of the invention
In view of this, the utility model patent provides a kind of demonstration instrument for teaching of measuring angle of friction, it adopts the mode of rotating rotary screw to drive hinged nut slider, and then drive push rod to promote turning supporting seat, make the flip angle of turning supporting seat can fine adjustments, can read by the angle graduated scale of side the flip angle of turning supporting seat simultaneously.
Realizing the technical scheme that the utility model object adopts is:
A demonstration instrument for teaching of measuring angle of friction, it comprises: a hinged turning device, comprises the base that is provided with chute, the turning supporting seat hinged with base; One push rod device, comprises the rotary screw being installed in chute, coordinates and the hinged nut slider that can slide in chute with rotary screw, and one end and hinged nut slider are hinged, the other end and the hinged push rod of turning supporting seat; One is fixed on base side, for measuring the angle graduated scale of turning supporting seat flip angle.
In a preferred embodiment, in turning supporting seat, place A measured piece, on A measured piece, place B measured piece.
Above-mentioned angle of friction is measured demonstrator, promotes to regulate the flip angle of turning supporting seat by screw rod, nut transmission and push rod, and then records the angle of friction between two testees by observe the glide rule reading of moment flip angle of B measured piece on A measured piece.
Brief description of the drawings
Fig. 1 is that in embodiment, angle of friction is measured demonstrator schematic diagram.
Fig. 2 is the gearing schematic diagram that in embodiment, angle of friction is measured demonstrator angular adjustment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As seen from Figure 1, Figure 2, a kind of angle of friction is measured demonstrator, comprises the base 1 that is provided with chute, the turning supporting seat 6 hinged with base; Be installed on the rotary screw 2 in chute, coordinate and the hinged nut slider 3 that can slide in chute with rotary screw 2, one end and hinged nut slider 3 are hinged, the other end and the hinged push rod 5 of turning supporting seat 6; One is fixed on base 1 side, for measuring the angle graduated scale 4 of turning supporting seat 6 flip angles; Two for measuring A measured piece 7 and the B measured piece 8 of angle of friction between it.
Angle of friction is measured demonstration: A measured piece 7 is positioned in turning supporting seat 6, and B measured piece 8 is positioned on A measured piece 7.Rotate rotary screw 2, thereby drive hinged nut slider 3 to slide in the chute of base 1, push rod 5 one end and hinged nut slider 3 are hinged, the other end and turning supporting seat 6 hinged.Hinged nut slider 3 drives push rod 5 when slip, overturn thereby promote turning supporting seat 6, is turned to after certain angle, and B measured piece 8 is down sliding from A measured piece 7 just.The flip angle of the instant reverse bearing 6 of two measured piece relative slidings is to record angle of friction, by scale value corresponding on reading angular rule 4, just can record angle of friction.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
