Abstract

The invention relates to a weighing tray which is characterized in that the weighing tray comprises a tray, a first connecting part, a second connecting part and a chassis which are sequentially arranged from top to bottom, wherein the tray comprises a disk-shaped part and a stainless steel pipe connected on the bottom surface of the disk-shaped part, a cylindrical hole is formed at one end of the first connecting part, a cylindrical part is arranged at the other end of the first connecting part, the cylindrical hole is formed at one head of the second connecting part, an external thread is arranged at the other end of the second connecting part, an internal thread is arranged at the top of the chassis, the stainless steel pipe of the tray is arranged in the cylindrical hole of the first connecting part, the cylindrical part of the first connecting part is arranged in the cylindrical hole of the second connecting part, and the external thread of the second connecting part is connectedwith the internal thread of the chassis. The weighing tray has the advantages of simple structure, light weight and convenient operation, and can simultaneously solve the thermal insulation problem between a thermal insulation box and an electronic scale and also avoid the problem of scalding an operator during the operation.

Description

technical field [0001] The invention relates to a weighing tray, which belongs to the technical field of petrochemical machinery. Background technique [0002] In the experimental device, considering that some materials need to be heated and weighed at the same time, these materials are usually placed in a beaker and heated in an incubator, and the weighing electronic scale must be placed outside the incubator. In the past, the structure supporting the beaker was supported by metal, and an asbestos pad was added between the support and the electronic scale. This structure is easy to cause heat loss, and when the operator takes the beaker, he needs to wear very thick gloves, which is inconvenient. Now this structure solves the defects of previous pallets and is easy to operate. Contents of the invention [0003] The purpose of the present invention is to provide a weighing tray with less heat dissipation and easy to use. [0004] In order to achieve the above object, the...
