Problems solved by technology

But this measuring car has only one wheel, the stability is not good, the wheel is easy to run off, the measured distance may be greater than the actual distance between two points
Moreover, the manufacturing technology requirements during the competition are relatively high, so the existing measuring vehicles can no longer meet the requirements

Abstract

The invention discloses a pure mechanical type three-dial kilometer metering car for distance measurement. The pure mechanical type three-dial kilometer metering car is characterized in that a drive shaft, a driven shaft, a first transmission shaft, a second transmission shaft, a third transmission shaft, a fourth transmission shaft and a fifth transmission shaft are mounted on a left side plate and a right side plate through bearings and are fixed on a bottom plate; drive wheels are arranged at two ends of the drive shaft, and driven wheels 7 are arranged at two ends of the driven shaft; a group of mutually matched gears is arranged on the drive shaft, the driven shaft and the transmission shafts; a handrail is arranged on the bottom plate; a millimeter dial, a decimeter dial, a meter dial, a millimeter pointer, a decimeter pointer and a meter pointer are arranged on the left side plate, the millimeter pointer is connected with the first transmission shaft, the decimeter pointer is connected with the second transmission shaft, and the meter pointer is connected with the third transmission shaft. The kilometer metering car is compact in structure and accurate in reading and can set a distance between any two points within 6 meters and ensure that the distance is linear.

Description

technical field [0001] The invention relates to a tool for measuring the straight-line distance between two points, in particular to a purely mechanical three-disc distance meter. Background technique [0002] It is not easy to make equidistant points on a field without any markings. Many people suffer from the lack of a straight-line distance measuring tool within 6 meters. In recent years, in the measuring carts that have appeared on the market, the reading display area is driven by gears, and there are also push rod devices. But this measuring car has only one wheel, the stability is not good, the wheel is easy to run off, and the measured distance may be greater than the actual distance between two points. Moreover, the manufacturing technology requirements during the competition are relatively high, so the existing measuring vehicles can no longer meet the requirements. Contents of the invention [0003] The purpose of the present invention is to provide a purely me...
