Abstract

The invention discloses an explaining device with a function of reducing measurement errors, and aims to improve the measurement reliability. The device specifically comprises a base, a back plate anda weighing mechanism, the outer wall of the bottom of the back plate is integrally arranged on the outer wall of the top of the base, and two side plates and a top plate are installed on the outer walls of the two sides and the outer wall of the top of the back plate through three groups of hinges respectively; a door plate is mounted on the outer wall of one side of one side plate through a hinge, and the door plate, the top plate, the back plate and the two side plates are all made of transparent acrylic materials; and a fixing mechanism for fixing the top plate and the side plates is alsoarranged on the top plate. By arranging a weighing table, a first level bubble and a pressure sensor, an object can be weighed conveniently, and the weighing table can be adjusted to be in a horizontal state by observing the first level bubble and utilizing an adjusting screw rod assembly, so that the weighing accuracy is guaranteed, and the errors are reduced; by arranging a balancing weight, thegravity center of the weighing table can be stabilized conveniently, and therefore the stability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of measuring and explaining devices, in particular to an explaining device with the function of reducing measurement errors. Background technique [0002] In the process of physics teaching, it is often necessary to use various explanation devices to assist teaching. Due to the limitations of instruments, experimental conditions, environment and other factors, the measurement cannot be infinitely accurate. There will be certain differences. If the measurement error is too large, it will not be conducive to the development of teaching. [0003] After searching, the Chinese patent application number is CN201710596970.6, which discloses a multifunctional physics teaching aid, including a test bench, the test bench includes a base plate, and a column connected to the base plate at one end, on which The other end of the upright column is connected with a pole ruler; a demonstration device, the demonstration devi...
