Dingan County is equipped with spring tension meter, and the spring tension meter is mounted laterally on stringer board, and spring tension meter is provided with pulling force scale
Simultaneously super outside, the side of T-shaped seat is provided with two guide rails parallel to each other, and the inner side of two guide rails is provided with chute, institute
State cunning in chute and set a movable plate, a brake pad is placed on the movable plate, the brake pad passes through a drawstring and the spring
The spring carrier arm connection of tensiometer.
As the further improvement to above-mentioned technical proposal：
Preferably, the upper surface of the brake pad is provided with multiple grooves for being used to place counterweight.
It is furthermore preferred that the size of multiple grooves differs.
Preferably, the movable plate is the panel that upper and lower surface roughness differs.
Compared with prior art, the utility model has the advantage of：
(1) spring tension meter level is laterallyd secure peace by friction experiment device of the present utility model by setting T-shaped seat
On the stringer board of T-shaped seat so that the one side that spring tension meter is provided with pulling force scale is super outside, in this way, passing through spring tension
Meter can easily read the size of frictional force, the friction experiment device is simple in construction, it is easy to use, can intuitively clearly
Show frictional force.
(2) movable plate is slidably installed in the interior side chute of guide rail, by pulling the movable plate to make brake pad and movable plate
Generation relative motion, frictional force is produced, chute limits transverse shifting and the up and down motion of movable plate, can only be drawn to away from spring
One end of power meter is extracted out, avoids influence of other active forces to brake pad, experimental result is truer.
