Description

Technical Field

[0001] The invention relates to the technical field of sports competition equipment, in particular to a scoring and indicating device for a pickleball doubles competition. Background Art

[0002] Pickleball is a sport that mixes elements of tennis, table tennis, and badminton. It originated in the United States and was created by three families in Washington State in the early 1960s. Pickleball can be played indoors or outdoors and is usually played on a court similar to a tennis court. The pickleball court measures 20 feet (about 6.1 meters) wide and 44 feet (about 13.4 meters) long. In the center of the court is a low horizontal volleyball net similar to the net in a tennis court, usually 34 inches (about 86 cm) high. The rackets used in the game are similar to table tennis rackets, but slightly larger than table tennis rackets, and the ball is similar to table tennis, but slightly larger than table tennis. The rules of pickleball are simple and easy to learn. It is usually a doubles game played by two pairs of players. The goal of the game is to score by bouncing the ball onto the opponent's court, similar to tennis and table tennis. The characteristics of pickleball include relatively slow ball speed and high requirements for skills and tactics, and it is suitable for people of all ages to participate. In the prior art, a pickleball doubles match usually requires manual scoring and voice instructions by the referee, which consumes the referee's physical strength during a long game, and misjudgment may occur if the referee only relies on naked eye observation.

[0027] The top end of the fixed support column 21 is fixedly connected to a connecting piece 24, the outer surface of the movable support rod 23 is sleeved inside the connecting piece 24, the groove on the outer surface of the connecting piece 24 is rotatably connected to a supporting rotating rod 26, the supporting rotating rod 26 is symmetrically arranged on both sides of the connecting piece 24, the output end of the supporting rotating rod 26 is fixedly connected to a fixed shaft 27, and both ends of the fixed shaft 27 pass through the supporting rotating rod 26.

[0028] The outer surface of the fixed shaft 27 is rotatably connected with a rolling block 28, and a first slide groove 14 is provided on the lower surface of the electric control box 3. The first slide groove 14 is symmetrically arranged on both sides of the movable support rod 23, and a second slide groove 15 is provided on the inner wall of the first slide groove 14. The outer surface of the rolling block 28 is extruded and adapted to the inner surface of the first slide groove 14, and the two ends of the fixed shaft 27 are slidably connected to the inner surface of the second slide groove 15.

[0029] The outer surface of the fixed frame 51 is fixedly connected to the outer surface of the anti-slip base 1, the inner part of the L-shaped movable plate 52 is sleeved on the outer surface of the fixed frame 51, the moving wheels 53 are symmetrically arranged on both sides of the fixed frame 51, and the bottom end of the guide rod 54 is fixedly connected to the upper surface of the L-shaped movable plate 52.

[0030] The outer surface of the guide rod 54 is sleeved inside the fixing frame 51 , the end of the second spring 55 is fixedly connected to the upper surface of the L-shaped movable plate 52 , and one end of the second spring 55 away from the L-shaped movable plate 52 is fixedly connected to the bottom of the inner surface of the fixing frame 51 .

[0031] A first plug hole 56 is provided inside the fixing frame 51 , a second plug hole 57 is provided inside the L-shaped movable plate 52 , a fixed placement ring 59 is fixedly connected to the outer surface of the L-shaped movable plate 52 , and limit pins 58 are provided inside the first plug hole 56 and the second plug hole 57 .

[0032] When in use, the entire device is moved to a position flush with the net next to the competition venue through the mobile device 5. The two high-definition cameras 7 are respectively aimed at the competition venues on both sides of the net through the built-in acceleration sensor and gyroscope of the high-definition camera 7, so as to facilitate the shooting of the movements of the two groups of athletes during the game, so as to obtain whether the athletes have committed fouls during the game. When a group of athletes scores, the score button 10 on that side is pressed, and the scoring indicator light 8 on that side is lit. With the cooperation of the single-chip microcomputer in the electric control box 3, the scoring display screen 6 updates the score data. At the same time, the buzzer alarm built into the electric control box 3 performs corresponding voice broadcasts through the sound outlet 13 to prompt the athletes and the audience on the scene of the current score. When the athlete makes a mistake, the corresponding mistake button 11 is pressed, and the number of mistakes is displayed on the scoring display screen 6, and a voice broadcast appears to remind the athlete. When the athlete commits a foul, the corresponding foul button 12 is pressed, and the number of fouls is displayed on the scoring display screen 6, and the foul indicator light 9 is lit, and a voice broadcast appears to remind the athlete.

[0033] When the entire device needs to be moved by the moving device 5, the L-shaped movable plate 52 is moved downward to the bottom of the inner surface of the fixing frame 51, and the guide rod 54 moves downward accordingly, and the second spring 55 is stretched. At this time, the second plug hole 57 is aligned with the first plug hole 56, and the limit pin 58 is inserted into the second plug hole 57 and the first plug hole 56 at the same time, so that the L-shaped movable plate 52 is limited to the current position. After both moving devices 5 complete the above operations, the moving wheels 53 contact the ground and support the entire device, and the anti-slip base 1 remains suspended. The moving wheels 53 make the movement of the entire device easier. When reaching the appropriate position of the competition venue, the limit pin 58 is pulled outward to disengage it from the first socket 56 and the second socket 57. Under the elastic force of the second spring 55, the L-shaped movable plate 52 is pulled upward. When the second spring 55 returns to its original length, the moving wheel 53 leaves the ground, and the anti-slip base 1 contacts the ground and supports the entire device, so that the contact area and friction between the entire device and the ground are increased, thereby improving the stability of the device and avoiding the device being hit during the game to affect the shooting accuracy of the high-definition camera 7. The pulled out limit pin 58 is placed in the fixed placement ring 59.

[0034] Through the support device 2, in the process of moving the entire device through the moving wheel 53 of the moving device 5, the device will be subjected to a certain vibration. The elastic force of the first spring 25 converts most of the vibration into elastic potential energy, so that the vibration transmitted to the electric control box 3 is reduced, thereby preventing the vibration from affecting the service life of the working components in the electric control box 3. During the movement, the movable support rod 23 will move up and down slightly due to the vibration, driving the electric control box 3 to move, and the supporting rotating rod 26 will rotate due to the pressure. The rolling block 28 rolls in the first slide groove 14, and the fixed shaft 27 slides in the second slide groove 15. With the cooperation of the two supporting rotating rods 26, the supporting effect on the electric control box 3 and the structure above it can be improved.

[0035] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
