Detection device for degree of balance of shuttlecock based on Bernoulli principle

Abstract

The invention relates to the technical field of sports equipment designs and discloses a detection device for degree of balance of a shuttlecock based on Bernoulli principle. The detection device comprises a bearing, a rotating column, a fan-shaped groove and an arc-shaped metal sheet. The shuttlecock is arranged at the lower end of a pull rope; a swing bar is connected in the detection device andthe swing bar comprises a soft layer, a spherical metal sheet and a first spring; magnet blocks are arranged on the upper part of a supporting plate; a second spring is arranged between the magnet blocks; and coils corresponding to the magnet blocks are arranged outside a round supporting plate. By increasing the swing amplitude of the shuttlecock, the pull rope drives the swing rod to rotate, the spherical metal sheet at the left end of the swing rod is in contact with the arc-shaped metal sheet, a magnetic field generated by the coiler adsorbs the magnet blocks, the magnet blocks drive theouter side end of the supporting plate to shrink, and the shuttlecock falls off from the supporting plate. The structure solves the problem that an existing detection device for degree of balance of the shuttlecock is low in detection precision and detection efficiency and injures eyes.

Description

technical field [0001] The invention relates to the technical field of sporting goods design, in particular to a badminton balance degree detection device based on the Bernoulli principle. Background technique [0002] Badminton is a sport that can be played both indoors and outdoors. According to the number of participants, it can be divided into singles and doubles, and the emerging 3-on-3. Badminton racket is made of racket face, racket shaft, handle and the joint of racket frame and racket shaft. The length of a racket does not exceed 680 mm, of which the length of the handle and shaft does not exceed 41 cm, the length of the racket frame is 28 cm, and the width is 23 cm. The frame is harder and the racket shaft is more flexible. [0003] During the manufacturing process of the shuttlecock, due to the accumulation of various errors in the manufacturing process, the shuttlecock shakes and swings during flight, and such shuttlecocks must be screened. The original scree...
