Problems solved by technology

[0003] At present, the artificial experience method is used to detect the elasticity of basketballs before large-scale competitions at home and abroad, that is: the inspectors stand on the basketball court with the ball, and according to their own experience, place the basketball at a height of about 1.80 meters by hand, and then hold it The golfer evacuates quickly, makes the ball fall freely, bounces up, and then makes a rough estimate of whether the ball’s elasticity meets the requirements according to the corresponding height of the body part. As for the circumference and weight, it needs to be measured with a scale and a weighing device. Feasible, but the disadvantage is that it lacks enough science and rigor
[0004] After searching, there is no display of the detection device for basketball specifications

Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] Circumference detection:

[0053] like figure 1 Shown in (overall structure schematic diagram of the present invention): design vernier clamp 1, the first fixed clamp 2 and the second fixed clamp 12 three vertical boards on elastic detection platform 5 table tops, these three vertical boards and elastic The detection platform 5 is vertical;

[0054] like Figure 4 Shown in (top view of the present invention): two vernier calipers 3 are respectively designed on both sides of the vernier clamp 1 of the present invention, the first fixed clamp 2 and the second fixed clamp 12, and its fixed scale 14 is a steel ruler. It is also the sliding track of the vernier card plate 1.

[0055] like Figure 4 (top view of the present invention) and image 3 Shown in (partially enlarged schematic diagram of the present invention): vernier clamp plate 1 of the...

Abstract

The invention discloses a basketball specification detecting device, comprising a detection table bracket, wherein a fine-adjusting device is arranged at the bottom of the detection table bracket; an elastic detection platform, a 120 cm standard line and a 140 cm standard line are arranged on the detection table bracket; and the elastic detection platform is provided with a perimeter detecting device, an elasticity detecting device and a weight detecting device. According to the basketball specification detecting device disclosed by the invention, the defect of lacking strictness in the conventional artificial experience measurement method is solved, the weight detecting device, a diameter measuring (the perimeter detecting) device and the elasticity detecting device are combined integrally, so that a special basketball specification detecting device is formed; the basketball specification detecting device aims at detecting the specification of a basketball scientifically, strictly, comprehensively, conveniently and quickly, and clearly judging whether the detected basketball meets requirements of Basketball Rule issued by an international basketball federation, thereby more scientifically and strictly providing a guarantee for basketball competitions and trainings.

Description

technical field [0001] The invention relates to a sports equipment detection device, in particular to a basketball specification detection device. Background technique [0002] The "Basketball Rules" promulgated by the International Basketball Federation have clear requirements for the basketball specifications used in competitions, namely: the circumference of the basketball shall not be less than 0.749 meters (74.9 cm), and shall not be greater than 0.780 meters (78 cm); the weight shall not be less than 567 grams. , not more than 650 grams; after the basketball is inflated, the ball falls from a height of 1.80 meters (measured from the bottom of the ball) to the ground of the court, and the height of the rebound shall not be lower than 1.20 meters, nor higher than 1.40 meters ( measured from the top of the ball). [0003] At present, the artificial experience method is used to detect the elasticity of basketballs before large-scale competitions at home and abroad, that i...
