Description

Wind-proof device of electronic balance

Technical Field

The utility model relates to the technical field of electronic balances, in particular to a wind-proof device of an electronic balance.

Background

People refer to a balance for balancing the gravity of a weighed object by electromagnetic force as an electronic balance, and the electronic balance has the characteristics of accurate and reliable weighing and quick and clear display. Electronic balances have been widely used as measuring instruments in the fields of industry, medical treatment, chemical industry and the like, but with the progress of society, the requirements on the balances are also higher and higher; and the windshield is an important component in the dustproof structure of the electronic balance.

Due to the rapid development of science and technology, people have higher and higher precision requirements on the electronic balance, and due to the fact that the influence of air flow disturbance on a measurement result can be reduced, the electronic balance windshield plays an increasingly important role. For example, patent publication number CN218239050U discloses a balance windshield comprising a base, corner posts, top frame and baffle; the two groups of corner supports are locked with the base; the top frame is locked with the corner support column; the base and the top frame are provided with sliding grooves; slots are formed in the base, the corner support and the bottom frame; the baffle is connected with the chute in a sliding way, and the baffle is matched with the slot in an inserting way. Compared with the traditional fan housing structure, the strength and stability of the integral structure are improved, the detachable assembly among the components is easy to disassemble, maintain and replace, the testing precision of the balance is guaranteed, and the testing error is reduced, wherein the baffles at the left side and the right side are not fixed and can slide in the sliding grooves in the base and the top frame, so that the baffles are opened and closed.

In the use process of the wind-proof device of the electronic balance, as the movable side plates are positioned at the left side and the right side, an operator needs to keep a certain height between the sample and the scale pan to enter the wind-proof cover, and then the sample descends by a certain height and is placed on the scale pan, so that the existing wind-proof cover has a certain requirement on the height. In order to ensure that the volume of the draft shield is not excessive, there are generally limitations on both the length and width dimensions. In actual weighing, sometimes the sample is a sheet-like article of great length or width, such as a square filter membrane of 200mmx250mm gauge. Therefore, the sample cannot be placed in the windshield, the windshield can prevent the sheet-shaped articles with larger measurement length or width from being placed, the sheet-shaped articles cannot be suitable for weighing the articles with different specifications and sizes, the application range is small, and the practicability is poor.
