Description

Technical Field

[0001] The utility model relates to the technical field of sports training equipment, in particular to a sports long jump measuring device. Background Art

[0002] As a sport, long jump can measure the physical fitness of the human body. Long jump is divided into two categories: sprint jump and standing long jump. Sprint jump usually has a sand pit to protect the long jumper. Standing long jump is less dangerous and is usually measured by a measuring ruler. After standing long jump, some long jumpers will move slightly, resulting in inaccurate measurement results. Therefore, we propose a sports long jump measurement device. Existing standing long jump measurement jump distance generally uses traditional line drawing distance measurement. The drawn line will become blurred after multiple steps, and the line drawing measurement jump distance reading will have errors. Measuring equipment generally uses long boards for measurement. Long boards are inconvenient to carry and lay, and multiple long boards must be spliced ​​to achieve stability of the connection position after splicing. Otherwise, the disconnection will lead to inaccurate measurement, and serious safety accidents may occur. Utility Model Content
