Description

Technical Field

[0001] The utility model belongs to the technical field of electronic balances, and in particular relates to an electronic balance. Background Art

[0002] Chinese patent application number 202321158929.8 discloses an electronic balance, which is placed in a controlled position. After the electronic balance is placed, the first ring body and the second ring body, and the second ring body and the outer wall of the body can be rotated through a connecting rod by the gravity of the electronic balance itself to perform adaptive adjustment. After the adjustment is completed, the body can always be vertical in the placed position, without manual adjustment, and the adjustment is accurate. It can be automatically adjusted by simply placing it flat; the connection port on each first L-shaped plate is connected to an external air pump, and the air pump is used to intake or exhaust air, so that the second L-shaped plate can be slidably and telescopically connected inside the first L-shaped plate. Under normal conditions, the second L-shaped plate extends outward, and when the adjustment mechanism adaptively rotates, it can drive the second gear to rotate. After the rotation is completed, the air pump is used to exhaust air, so that the second L-shaped plate moves to one side of the first L-shaped plate to clamp the second gear. The friction plate can limit the second gear from rotating, thereby limiting the adjusted position.

[0003] However, most existing electronic balances are divided into two types: one is equipped with a protective case, and the other is not. Although the electronic balance without a protective case is convenient and practical, it is easy to cause a certain impact on the measurement results during the measurement process; although the electronic balance with a protective case has high measurement accuracy, it is large in size, resulting in a large space occupied when stored and poor practicality.
