Problems solved by technology

[0003] When using a scale to measure the weight of an object, the spherical object is easy to roll on the top of the scale, and it is easy to increase the error of the weight measurement of the object
And the existing method of placing the object at the top corner of the scale makes the center of gravity of the entire object shift to the outside of the scale, thereby affecting the normal reading of the scale and causing serious cheating

Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The invention provides an anti-cheating detection device suitable for weighing instruments, such as figure 1 As shown, it includes a scale body 1, the top of the scale body 1 is provided with a pressure plate 2, the top of the pressure plate 2 is provided with a top plate 3, the outer side of the top plate 3 is provided wi...

Abstract

The anti-cheating detection device comprises a scale body, a pressing plate is arranged at the top of the scale body, a top plate is arranged at the top of the pressing plate, and an outer frame is arranged on the outer side of the top plate. A spherical object rolls at the top of a top plate, the top plate starts to rotate at the tops of two supporting rods with a center rod as the circle center under the pressing of the weight of the object, the top plate enables a vertical rod to move downwards in a pressing plate through a through groove by means of a sliding frame, and the top end of the vertical rod slides in a groove of a sliding groove through a clamping rod till the bottom face of a nut is attached to the top face of the pressing plate; the top plate is matched with the outer frame to extrude the elastic block through the pulling frame, excessive inclination of the top plate on the inner side of the outer frame can be avoided through elastic force of the elastic block, inclination of the top plate is matched with the outer frame to limit a spherical object to the bottom of the inclined face of the top plate, and therefore the object is prevented from rolling freely on the top of the top plate. And scale body measurement error increase caused by object movement is avoided.

Description

technical field [0001] The invention belongs to the technical field applicable to weighing instruments, in particular to an anti-cheating detection device and method applicable to weighing instruments. Background technique [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. Weighing instruments are mainly composed of three parts: load-bearing system (such as weighing pan), force transmission conversion system (such as lever force transmission system) and display system (such as dial). Scales can be divided into three categories: mechanical scales, electronic scales, and electromechanical combination scales according to their structural principles. [0003] When using a weighing instrument to measure the weight of an object, the spherical object is easy to roll on the top of the weighing instrument, and it is easy to increase the error of measuring the weight of the object. And th...
