Description

Technical Field

[0001] The invention relates to the technical field of sports equipment detection, in particular to a badminton racket center of gravity detection device. Background Art

[0002] The center of gravity position of a badminton racket is an important indicator for evaluating the performance of a badminton racket, which is beneficial for different types of professional athletes such as singles and doubles, as well as badminton amateurs to choose the right racket. A reasonable center of gravity position of a badminton racket will help improve and optimize the structural mechanical properties of the badminton racket, so that badminton racket manufacturers and marketers can better meet the needs of professional athletes and amateurs in choosing badminton rackets.

[0003] Patent document CN201364224Y discloses a badminton racket center of gravity position detection device, which includes a detection platform, a ruler, and a support shaft. The support shaft parallel to the detection platform is installed above the detection platform; a ruler is installed on the detection platform, and the length direction of the ruler is perpendicular to the support shaft. During the detection, the detection platform is first placed in a horizontal state, and the badminton racket is placed on the support shaft, and the racket shaft of the badminton racket is perpendicular to the support shaft. Then adjust the contact point between the badminton racket and the support shaft so that the badminton racket is in a horizontal balance state. At this time, the contact point between the badminton racket and the supporting shaft is the center of gravity of the badminton racket. Then look down at the detection table, make your sight vertical to the ruler, read the scale on the ruler corresponding to the bottom of the handle of the badminton racket, and you can get the distance from the center of gravity of the badminton racket to the bottom of the handle. Although the center of gravity of the badminton racket can be measured, it is necessary for relevant personnel to hold the badminton racket by hand to operate it during measurement, which increases the operation intensity of relevant personnel.
