Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a weighing parameter testing machine. Background Art

[0002] A weighing instrument is an instrument that uses Hooke's law or the principle of lever balance of force to measure the mass of an object. A weighing instrument mainly consists of three parts: a load-bearing system (such as a scale pan), a force transmission conversion system (such as a lever force transmission system) and an indicating system (such as a dial). According to the structural principle, weighing instruments can be divided into three categories: mechanical scales, electronic scales, and electromechanical combined scales.

[0003] The "A Fully Automatic Scale Testing Machine" provided in the Chinese Utility Model Patent Application with Publication Number CN216116345 U includes a cabinet body, on which a height-adjustable mounting mechanism is arranged, to which an electric push rod passing through the mounting mechanism is fixedly connected, and the output end of the electric push rod is fixedly connected to a threaded inner rod through a steel wire. The mounting mechanism provided in the present invention can drive the electric push rod as a whole to adjust its height, thereby reducing the height of the electric push rod as a whole, and at the same time utilizing the function of the bearing mechanism to increase the number of weights, thereby solving the existing problem of manually loading weights onto the scale platform, and only being able to add weights individually, and being unable to add a large number of weights at one time, thereby reducing the practicality of the testing machine. At the same time, the existing testing machine is relatively inconvenient to transport and carry due to its high height and being an integral whole.

[0004] When testing a scale, weights need to be placed at five points on the top of the scale pan for testing, namely the four corners and the center point, to determine whether the weights measured at the five points are consistent, thereby achieving the purpose of testing the accuracy of the scale.

[0005] However, when the weights are placed on the testing machine of the prior art for testing, it is not convenient to perform testing according to the positions of the five points on the top of the weighing device, and the purpose of accurate testing cannot be achieved. Utility Model Content
