Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a javelin detection device to solve the problem that when measuring javelins, the length measurement results are prone to deviation, the measurement process is cumbersome, the measurement efficiency is poor, and the diameter of the javelins is measured with a tape measure. The measurement accuracy is very low, the measurement result is inaccurate, and it is very inconvenient to achieve accurate, simple and efficient measurement of the length and diameter of the javelin, so as to better screen the matching javelin for athletes

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with specific inventions.

[0034] A javelin detection device, combined Figure 1 to Figure 6 As shown, it includes a frame body 1, a pneumatic clamping device 2, a javelin distance measuring device 3, a javelin diameter measuring device 4 and a controller 7.

[0035] The frame 1 includes a rectangular frame 13, a horizontal top plate 11, a height adjustable leg 12, a rectangular hole a14 and a rectangular hole b15. The rectangular frame 13 is surrounded by a plurality of fixed rods, using standard aluminum profiles and connected with standard corner fittings to avoid the deflection of the theme frame caused by welding deformation; the horizontal top plate 11 is fixedly arranged on the top of the rectangular frame 13 and is a rectangular aluminum plate , Horizontal beads are installed near the four sides of the horizontal top plate 11, which are used to adjust the horizontal observation point whe...

Abstract

The invention discloses a javelin detection device, and the device comprises a frame body. A pneumatic clamping device, javelin distance measuring devices which are disposed at two sides of the pneumatic clamping device and are used for measuring the length of a javelin and javelin diameter measuring devices which are disposed at two sides of the javelin and are used for measuring the diameter ofthe javelin are disposed above the frame body. A controller for controlling the overall operation of the control device is disposed below the frame body. A controlled end of the pneumatic clamping device, controlled ends of the javelin distance measuring devices and controlled ends of the javelin diameter measuring devices are connected to the output end of the controller. According to the invention, the frame body is provided with the pneumatic clamping device for achieving the clamping of the javelin, and then javelin distance measuring devices which are disposed at two sides of the pneumatic clamping device are used for measuring the length of the javelin, and finally the javelin diameter measuring devices which are disposed at two sides of the javelin are used for measuring the diameter of the javelin, thereby achieving the precise, simple, convenient and efficient measuring of the length and diameter of the javelin and enabling the javelin to be quickly matched with an athlete.

Description

Technical field [0001] The invention relates to the technical field of sports training equipment, in particular to a javelin detection device. Background technique [0002] The javelin is a throwing event in track and field. The athlete throws the javelin after a run-up. Javelin throwing is a more complex multi-axis rotation project. Its complete technology is to obtain momentum by holding a gun on the shoulder through a pre-run-up and connecting throwing step, and then exert an explosive final force on the longitudinal axis of the javelin to move the javelin Throw it over the shoulder. [0003] With the improvement of students' overall quality, more and more attention is paid to sports competitions and sports, and the manufacture of sports goods also requires safety, environmental protection, convenience and durability. The javelin is a must-have item for the sports meeting. The measuring device for the javelin is currently single in variety, heavy in weight, inconvenient to car...
