Convenient-reading tray balance

Abstract

The invention discloses a convenient-reading tray balance. The convenient-reading tray balance comprises a base, a balance arm, a pointer, weighing disk brackets and weighing disks, wherein the base is connected with the balance arm, the pointer vertical to the balance arm is mounted at the middle of the balance arm, the weighing disk brackets are respectively mounted at the two ends of the balance arm symmetrically, the weighing disks are arranged on the weighing disk brackets, a graduated scale is mounted on the balance arm, the graduation marks of the graduated scale are upper-lower marks, a balance rider is mounted on the graduated scale in a sliding manner, and a magnifier is mounted on the surface of the balance rider. Through the manner, the convenient-reading tray balance disclosed by the invention has the advantages that the graduation marks of the graduated scale are the upper-lower marks, so that the convenient-reading tray balance is applicable to the use by all kinds of people and can be conveniently operated by even left-handed, and the errors of weighing results can not be caused; and a graduation indicated by the balance rider can be magnified by the magnifier, so that the viewing is facilitated, the reading can be accurate, and the errors of the weighing results are avoided.

Description

technical field [0001] The invention relates to the field of item weighing, in particular to a tray balance that is convenient for reading. Background technique [0002] Tray balance is a kind of weighing instrument with low precision. It is made by the principle of Roberwell. The weighing pan is stressed on the bottom plane and can automatically move to the center position in the non-center position to form a balance. The left tray of the traditional tray balance puts the items to be weighed, the right tray puts weights or items of known weight, and the floating code on the moving scale balances the tray balance. However, some people are used to doing things with their left hands in life. It is not very convenient to operate traditional pallet balances, and sometimes mistakes are often made, resulting in losses. Although the tray balance is not a very precise instrument, it also requires the accuracy of the weighing results. The scale marks on the tray balance are too smal...

Problems solved by technology

The left tray of the traditional tray balance puts the items to be weighed, the right tray puts weights or items of known weight, and the floating code on the moving scale balances the tray balance. However, some people are used to doing things with their left hands in life. It is not very convenient to operate the traditional tray balance, and sometimes mistakes are often made, resulting in losses

Although the tray balance is not a very precise instrument, it also requires the accuracy of the weighing results. The scale marks on the tray balance are small and people cannot see clearly, resulting in errors in the weighing results.
