Combination of multilayer scale pan and counterweight bearing discs

The utility model discloses a combination of a multilayer scale pan and counterweight bearing discs. The combination comprises the multilayer scale pan and counterweight bearing discs. The multilayer scale pan comprises a U-shaped support and a support seat. The U-shaped support comprises a first sidewall and a second sidewall which extend in the vertical direction. The first sidewall and the second sidewall are provided with multiple layers of first supporting bars and multiple layers of second supporting bars, respectively. The number of layers of the first supporting bars is the same as that of the second supporting bars. The top supporting surfaces of each first supporting bar and each second supporting bar in the same layer are arranged in the same horizontal surface. The support seat is disposed under the U-shaped support and is used for positioning and installing the U-shaped support. Each counterweight bearing disc is a sheet structure equipped with a central recess. Each counterweight bearing disc is arranged on the corresponding first supporting bar and the corresponding second supporting bar in the same layer. The combination may effectively solve a problem of eccentric load errors in a counterweight detecting process. When five layers of supporting bars and five counterweight bearing discs are provided, a prescription that at most five counterweight combinations are required by Chinese counterweight detecting rules can be satisfied.
