Embodiment 1

[0019] Such as figure 1 As shown, a device for calculating the area of ​​an irregular figure includes an image zoom ruler 1. The image zoom ruler 1 can adopt a technical solution similar to the application number 94226945.4. The rod of the image zoom ruler 1 is provided with an equidistant adjustment hole 15. The image zoom ruler 1 has a fixed end 11 , a proximal movable end 12 , and a distal movable end 13 . Both the proximal movable end 12 and the distal movable end 13 are provided with a cylinder 14 . The cylinder 14 is connected with the proximal movable end 12 and the distal movable end 13 through threads, and the up and down position of the cylinder 14 can be adjusted by rotating the cylinder 14 .

[0020] A counting circuit, a display screen 3 and a switch 4 are arranged on the counting board 2 . Open switch 4, counting circuit and display screen 3 start to work. Evenly arranged squares 21 are arranged on the top surface of the counting board 2, and the surroundings o...

Abstract

The invention relates to the technical field of metering equipment for measuring the area and particularly relates to an irregular pattern area calculation device. The device comprises an image scaling ruler (1) and a counting plate (2). The image scaling ruler (1) is provided with a fixed end (11), a proximal-end movable end (12) and a distal-end movable end (13). The proximal-end movable end (12) and the distal-end movable end (13) are respectively provided with a column body (14). The counting plate (2) is provided with a counting circuit. Evenly arranged square blocks (21) are distributed on the top surface of the counting plate (2). All the square blocks (21) are the same in area. Every time the column body (14) of the distal-end movable end (13) presses down one square block (21), the counting circuit completes one counting operation. The counting plate (2) is provided with a display screen (3) and a switch (4). The device has the advantages of simple structure and convenient use. By the device, the area of an irregular pattern can be quickly estimated.

Description

technical field [0001] The invention relates to the technical field of metering equipment used for measuring areas, in particular to an irregular figure area calculation device. Background technique [0002] The invention with the application number 200510006063.9 discloses a method for calculating the area of ​​an irregular figure, specifically: draw the figure to be calculated on a thin sheet with a uniform thickness in proportion, cut out the figure for calculation, weigh the weight of the figure for calculation, and then take On the same slice, draw a regular figure that is convenient for measuring the area, cut out the regular figure slice, weigh the weight of the regular figure slice, measure the area of ​​the regular figure according to the ratio of the calculated figure, divide the weight of the regular figure slice by the regular figure Area, to calculate the weight per unit area of ​​the sheet, divide the weight per unit area of ​​the sheet by the weight of the cal...
