Embodiment 1

[0038] An experimental balance, comprising a balance main body, the balance main body includes a balance beam 1, a balance dial 2 and a bracket 3 arranged in the middle of the balance beam 1, and the bracket 3 includes a fixed plate 4, a column 5 and The base 6, the fixed plate 4, the column 5 and the base 6 can be detachably connected; the balance beam 1 is symmetrically provided with a weighing pan 7, and the weighing pan 7 is detachably connected to the balance beam 1;

[0039] Said balance beam 1 is provided with a sliding code 8 that can slide along the balance beam 1, said balance beam 1 is provided with a chute 9 parallel to the length direction of the balance beam 1 on both sides, and the bottom of the swimming code 8 is located at the corresponding position of the chute 9. A ball 10 is arranged inside, and the ball 10 protrudes from the code 8 and is stuck in the chute 9;

[0040] The weighing pan 7 is hinged to the balance beam 1; the balance beam 1 is located on bot...

Embodiment 2

[0042] This embodiment is further optimized based on Embodiment 1. The balance beam 1 is located at both ends of the chute 9 and is provided with plugs 11 movably.

[0043] The plug 11 can prevent the travel code 8 from slipping out of the chute 9, and when the travel code 8 is installed or disassembled, the fast installation or removal of the travel code 8 can be realized by opening or closing the plug 11.

Embodiment 3

[0045] This embodiment is further optimized based on Embodiment 1. There are two floating codes 8, which can increase the accuracy of measurement.

Abstract

The invention relates to the technical field of physics teaching experiment equipment, and discloses a quick weighing balance. The quick weighing balance comprises a balance body. The balance body comprises a balance crossbeam, a balancing dial and a bracket arranged at the middle part of the balance crossbeam. Weighing pans are symmetrically arranged on the balance crossbeam. The weighing pans are hinged with the balance crossbeam. The balance crossbeam is movably provided with blocks which restrain swinging of the weighing pans at two sides of a hinging point between the weighing pans and the balance crossbeam. According to the quick weighing balance, before weighing, the blocks are connected with two sides of the balance crossbeam for reducing the swinging range of the weighing pans, thereby realizing higher speed in stabilizing the weighing pans in weighing. Not only is higher stability of the balance in weighing realized, but also higher weighing speed is obtained.

Description

technical field [0001] The invention relates to the technical field of physics teaching experiment equipment, in particular to a fast weighing balance. Background technique [0002] Experimental equipment mainly refers to the experimental instruments and tools specially used by students in class. Including junior high school and high school physics experiment box, chemistry experiment box, biology experiment box, microscope, magnifying glass, voltmeter, ammeter, test tube, beaker, evaporating dish, alcohol lamp, gas washing bottle, funnel, measuring cylinder, balance, capacity Single-piece experimental instruments such as bottles and gas measuring devices. [0003] The existing weighing pan is generally hinged with the beam of the balance. After the object to be weighed or the weight is placed on the weighing pan, the weighing pan will shake left and right, causing the balance to be unstable. After the weighing pan stops swinging, In order to accurately measure the weight ...
