Standard weights for calibrating container overload and off-center load detection devices

Abstract

This utility model relates to a standard weight for calibrating a container overload detection device, comprising a weight base, which includes an upper base and a lower base arranged vertically. The upper base has a central square hole, and the lower base has a central column. The central column includes a square shaft section and a circular shaft section arranged vertically. A central lifting structure is provided at the top of the square shaft section, and an upper base receiving groove is provided at the bottom of the upper base. The standard weight also includes a counterweight placement component rotatably sleeved around the circular shaft section. The counterweight placement component and the circular shaft section are positioned after rotation via a locking structure. The counterweight placement component has multiple pairs of upward-facing counterweight placement slots. The two counterweight placement slots in each pair are symmetrical about the axis of the circular shaft section, and adjacent pairs of counterweight placement slots are spaced apart circumferentially along the circular shaft section. This utility model solves the technical problem in the prior art where it is difficult to ensure that the center of gravity of the standard weight coincides with its geometric center during configuration.
