Counter balance capable of protecting knife edge of balance

Abstract

The invention discloses a counter balance capable of protecting a knife edge of a balance. The counter balance comprises weighing trays, a bracket of the weighing trays, a balance arm, a vertical supporting arm, the knife edge and a base, wherein the bracket of the weighing trays is connected with the balance arm through the knife edge fixed on the balance arm, the weighing trays are supported by the bracket of the weighing trays, a lower end of the bracket of the weighing trays is connected with the vertical supporting arm, the vertical supporting arm stretches into a hole on the base, and a groove is arranged on the base. Through the manner, in the counter balance capable of protecting the knife edge of the balance provided by the invention, two methods are adopted to protect the knife edge of the counter balance, different methods are applicable to different situations, and the counter balance has the advantages of simple for operation and capability of keeping the knife edge sharp and the counter balance sensitive and increasing accuracy of a weighing result.

Description
