[0002] Inertial balance is a device that uses the vibration method to measure the inertial mass of an object. Its main components are a weighing platform for placing weights or objects to be measured, a fixed platform for fixing the entire device, and two identical pieces connecting the fixed platform and the weighing platform. Shaped steel bars, several identical weights, and weight clips for fixing weights can be used for inertial physics experiments on objects. The original equipment has a single measurement method when used, cannot adjust the length and the limit effect is poor, and the overall operation is troublesome. It is not easy to use, and a kind of inertia scale device for university physics experiments is proposed to meet the above requirements

The invention belongs to the technical field of inertial scale devices, and particularly relates to an inertial scale device for a college physics experiment. The device comprises a supporting rod, a connecting block is mounted at the upper end of the supporting rod by lifting an adjusting screw rod, a vibration arm is arranged in the connecting block, and gear teeth for adjustment are arranged at the bottom end of the vibration arm. A stop block for limiting is mounted at the rear end of the vibrating arm. By arranging the vibration arm and a rotating gear, the length of the vibration arm can be conveniently adjusted, inertia experiments under different lengths can be conveniently tested, the experiment variability is increased, by arranging a stand column and a first sliding groove, the stand column can slide conveniently, the experiment can be conveniently carried out, time is saved, and the experiment efficiency is improved; and the stand column is fixed by arranging the clamping block and the clamping groove, inaccurate experimental data caused by deviation ofa movable measuring instrument is avoided, to-be-measured weight is connected more stably in the measuring platform by arranging the groove and the movable plate, and a condition that the to-be-measured weight vibrates and falls out to affect the experiment is avoided.
