Problems solved by technology

Since the two ends of the supporting rod connected to the piston and the horizontal tray are directly set in the cylinder filled with water, when weights or objects to be weighed are placed in the horizontal tray, the supporting rod is easy to tilt, and the piston and the inner wall of the cylinder Friction will occur, reducing the accuracy of its weighing items, and it is impossible to ensure that the hydraulic balance is in a horizontal state when weighing items

Abstract

The present invention discloses a hydraulic balance for weighing items. The hydraulic balance comprises a base, a horizontal level gauge arranged on the base, a vertically arranged U-shaped tube, and a tray support rod. The base is fixedly provided with a support structure which supports the U-shaped tube. Two openings of the U-shaped tube are equipped with an integrated sealing cover with round holes at two sides. The round holes of the sealing cover are consistent with the centers of the openings of the U-shaped tube. One end of the tray support rod with a piston is sleeved in the opening of one side of the U-shaped tube, and the other end goes through the round hole of the sealing cover and is connected to a tray. When a weighed item or weight is placed in the tray, the tray support rod slides up and down vertically in the round hole of the sealing cover, the friction phenomenon of the piston of one end of the support rod and the inner wall of the U-shaped tube caused by the inclination of the support rod is prevented, thus the precision of weighing the item is raised, and preferably the hydraulic balance can be conveniently adjusted to a horizontal state by adjusting a ground foot bolt.

Description

technical field [0001] The invention belongs to a balance for weighing items, in particular to a hydraulic balance for weighing items. Background technique [0002] All kinds of balances are frequently used items for people to weigh items, especially in laboratories. The current balance scales are mainly divided into electronic balances and mechanical balances. Chinese patent document CN202255572U also discloses a hydraulic balance. Including the base and the weight, a thin tube is arranged horizontally above the base, and the two ends of the thin tube are respectively connected with a vertically upward cylinder body, and a piston is respectively arranged in the cylinder body, and the piston is connected with a vertically upward supporting rod. Horizontal trays are used to weigh items. Since the two ends of the supporting rod connected to the piston and the horizontal tray are directly set in the cylinder filled with water, when weights or objects to be weighed are placed i...
