Electronic analytical balance for laboratory

Abstract

The invention provides an electronic analytical balance for a laboratory. The balance comprises a support base, a blower, a first hose, a dust box, a filter net, a second hose, a gas pipe, a rubber block, a shock absorbing spring, a baffle and a sponge plate, wherein the blower and the dust box are both installed on the upper end surface of the support base, the right end of the first hose is assembled at the left end of the blower, the filter net is installed on the right side inside the dust box, the lower end of the second hose is assembled on the left side of the upper end surface of the dust box, and the gas pipe is installed above the main body of the balance through a bent rod. The design above realizes the function of dust removal on the outer wall. The rubber block is attached tothe outer surface of the main body of the balance, the inner end of the shock absorbing spring is fixed on the outer surface of the rubber block, the outer end of the shock absorbing spring is assembled on the inner surface of the baffle, and the sponge plate is assembled on the outer surface of the baffle. The design above realizes the function of protection. The electronic analytical balance fora laboratory is simple in operation, realizes the function of dust removal of the outer wall, and has the advantages of strong protection, safety, stability and reliability.

Description

technical field [0001] The invention is an electronic analytical balance for a laboratory, which belongs to the technical field of electronic balances. Background technique [0002] Analytical balance is an instrument for accurately weighing a certain mass of material. Before weighing, check whether the balance is normal, whether it is in a horizontal position, whether the lifting lugs and ring codes are off, whether the inside and outside of the glass frame are clean, and the electronic analytical balance has automatic fault detection. Code setting, automatic calibration, full linear four-point calibration, overload protection and many other applications. [0003] In the prior art, there are still many deficiencies in electronic analytical balances. It lacks the external self-cleaning function, and dust is easy to adhere to the glass shell, reducing visibility. At the same time, it lacks protective functions. When the outer wall of the balance main body is hit, it is easy t...

Problems solved by technology

[0003] In the prior art, there are still many deficiencies in electronic analytical balances. It lacks the external self-cleaning function, and dust is easy to adhere to the glass shell, reducing visibility. At the same time, it lacks protective functions. When the outer wall of the balance main body is hit, it is easy to cause damage. The glass shell is damaged, even the balance is damaged, and the safety is low, so an electronic analytical balance for laboratory is needed to solve the above problems
