First, the backboard 1 and the two backboards should be made of suitable transparent materials, which have good integrity and the same hardness as the hardwood backboard with a thickness of 0.03m (3cm). They can also be made of 0.03m (3cm) thick hardwood painted white. 2. The dimensions of the backboard are: horizontal width 1.80m, vertical height 1.05m, and the lower edge is 2.90m off the ground. 3. Appropriate departments of FIBA, such as regional committees of regional or continental competitions or national federations of all domestic competitions, also have the right to approve the size of backboards with a horizontal width of 65,438+0.80m, a vertical height of 65,438+0.20m and a lower edge of 2.75m from the ground. 4. The front of the backboard should be flat, and: (1) All line drawings are as follows: a. If the backboard is transparent, use white; B, if opaque, use black; C, the width is 0.05m (5cm) (2) The hole on the edge of the backboard should be outlined with lines according to the above (1). (3) Draw a rectangle behind the hoop of each backboard according to the following requirements: A. The outer edge size is: 0.59 m (59 cm) in horizontal width and 0.45 m (45 cm) in vertical height. B. The upper edge of the bottom edge of the rectangle should be flush with the horizontal plane at the top of the hoop. 5. The backboard should be placed firmly according to the following requirements: (1) placed at both ends of the court, perpendicular to the ground and parallel to the end line; (2) Their centers should fall vertically on the court, with a distance of1.20m from the midpoint of the end line; (3) The backboard column is at least 2m away from the outer edge of the end line. In order to make the athletes see clearly, its color should be bright and obviously different from the background behind the end line. 6. The dressing on the two backboards should meet the following requirements: (1) For the bottom and edge of the backboard, the dressing should cover the bottom and side, and the distance between the side dressing and the bottom of the backboard should be at least 0.35 m (35 cm); (2) The minimum thickness of the bandage at the bottom hole of the backboard is 0.05m (5cm); (3) The front and back of the backboard are at least 0.02m (2cm) away from the bottom, and the minimum thickness of the dressing is 0.02m (2cm). 7. The backboard bracket should be wrapped as follows: (1) Any backboard bracket with a height below 2.75m behind the backboard should be wrapped on its lower surface until it is1.20m away from the front of the backboard. The minimum thickness of the dressing is 0.05m (5cm), and its density is the same as that of the backboard dressing. (2) All movable backboards must be bound with gadolinium on the base surface facing the court, and the minimum height of binding is 2.15m. The minimum thickness of dressing is 0.15m (15cm). 1, the basket should be made according to the following requirements: (1) solid iron bar with an inner diameter of 0.45 m (45 cm) and painted orange; (2) The minimum diameter of the ring strip is 0.0 17 m (17 mm) and the maximum diameter is 0.02 0 m (20 mm), and there is a small ring or something similar on the lower edge of the ring for hanging baskets; (3) They should be firmly installed on the backboard (see the note below), the top surface of the hoop should be horizontal, 3.05 meters away from the floor, and the distance from the two vertical sides of the backboard should be equal; Note: We suggest that it is best to install the hoop on the structural frame of the backboard, so that the stress of the hoop will not directly affect the backboard. (4) The closest point between the backboard surface and the inner edge of the hoop is 0.15m (15cm); (5) Compression hoops can be used. They must meet the following technical requirements: a, they must have exactly the same rebound characteristics as those of fixed iron rings. The constant pressure device should ensure these characteristics and protect the basket and backboard. The design and manufacture of the hoop can ensure the safety of the players; B, those with constant locking device, when the static load applied to the top of the hoop farthest from the hoop is less than 105 kg, the constant pressure device shall not be loose; C. When the constant pressure device is turned on, the hoop rotates downward, and the included angle with the original horizontal position shall not exceed 30 degrees; D, open the constant pressure device, no longer apply load, hoop should be transported back to its original position. 2. The basket is made of white thread and hung on the basket; Its structure should enable the ball to pass through the basket with a short pause. The clear length is not less than 0.40m (40cm) and not more than 0.45m (45cm).
