[0002] Pickleball is a sport that uses a racket to hit the ball. It originated from Benbridge Island in Seattle, USA. It is most appropriate to say that it is a hybrid sport of tennis, badminton and table tennis. It was invented by two people. The name of pickleball comes from a dog of one of the inventors; when the invention was first tried, the dog named Pickle often ran with the ball in his mouth. In terms of the amount of physical activity and mobility, pickleball is more active than badminton and table tennis, so it is better than badminton and table tennis in terms of physical exercise. The amount of activity and exercise of pickleball is less than that of tennis. People who can't play tennis well are suitable for playing pickleball as a regular exercise. Pickleball is suitable for all ages.

[0003] 74mm pickle ball is a conventional size of pickle ball, but currently there are no detailed requirements for hole positions and hole spacings for the through holes of 74mm pickle ball, resulting in that the stability of the existing 74mm pickle ball still has room for improvement, and the probability of excessive deviation of the flight trajectory is high. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Utility Model Content

[0021] See also Figure 1-3The utility model provides a technical solution: a 74mm pickle ball, comprising a pickle ball body 1, the diameter of the pickle ball body 1 is 74mm, the pickle ball body 1 is provided with a first layer of through holes 2, a second layer of through holes 3, a third layer of through holes 4, a fourth layer of through holes 5, a fifth layer of through holes 6, and a sixth layer of through holes 7 along the latitude and from top to bottom, the first layer of through holes 2 and the sixth layer of through holes 7 are arranged symmetrically with the 0° latitude of the pickle ball body 1 as the center plane, the first layer of through holes 2 and the sixth layer of through holes 7 each have four, the second layer of through holes 3 and the fifth layer of through holes 6 are arranged symmetrically with the 0° latitude of the pickle ball body 1 as the center plane, The through holes 3 on the second layer and the through holes 6 on the fifth layer are symmetrically arranged on the center plane, with eight holes each. The through holes 4 on the third layer and the through holes 5 on the fourth layer are symmetrically arranged on the center plane with the 0° latitude of the pickle ball body 1 as the center plane. The through holes 4 on the third layer and the through holes 5 on the fourth layer are symmetrically arranged on the center plane, with eight holes each. The distance between adjacent through holes 2 on the first layer and adjacent through holes 7 on the sixth layer is 12.5±0.5mm, the distance between adjacent through holes 3 on the second layer and adjacent through holes 6 on the fifth layer is 13.5±0.5mm, and the distance between adjacent through holes 4 on the third layer and adjacent through holes 5 on the fourth layer is 20±0.5mm.

[0022] The inner diameters of the first layer through holes 2, the second layer through holes 3, the third layer through holes 4, the fourth layer through holes 5, the fifth layer through holes 6 and the sixth layer through holes 7 are all consistent and are all 7.4±0.1mm, which is just suitable for the hole spacing of a 74mm pickle ball.

[0023] The distances between the first-layer through hole 2 and the two adjacent second-layer through holes 3, as well as between the sixth-layer through hole 7 and the two adjacent fifth-layer through holes 6 are 8.5±0.5mm and 14.5±0.5mm respectively; the distances between the second-layer through hole 3 and the two adjacent third-layer through holes 4, as well as between the fifth-layer through hole 6 and the two adjacent fourth-layer through holes 5 are 13.5±0.5mm respectively.

The wall thickness of the pickle ball body 1 is 1±0.1mm, and the weight of the pickle ball body 1 with a wall thickness of about 1mm is just right.

[0024] Manufacturing method: PVC is used as the raw material to prepare a mold. The inner diameter of the spherical mold cavity is 74mm, and the inner wall is provided with evenly arranged circular protrusions for forming the first layer through hole 2, the second layer through hole 3, the third layer through hole 4, the fourth layer through hole 5, the fifth layer through hole 6, and the sixth layer through hole 7 of the sphere. The mold is cleaned and coated with a layer of anti-sticking agent. A quantitative PVC powder is added into the mold through a powder weighing machine, melted at high temperature and formed into a sphere in the mold through rotating centrifugal force, and then cooled and fixed, and then the sphere is taken out to obtain a 74mm pickle ball. Finally, singeing and testing are carried out. The 74mm ball has the first layer through hole 2, the second layer through hole 3, the third layer through hole 4, the fourth layer through hole 5, the fifth layer through hole 6, and the sixth layer through hole 7 along the latitude, and the hole diameters are all 7.4mm, the first layer through hole 2 and the sixth layer through hole 7 correspond to each other and have four holes each, the second layer through hole 3 and the fifth layer through hole 6 correspond to each other and have eight holes each, and the third layer through hole 4 and the fourth layer through hole 5 correspond to each other and have eight holes each. The 74mm ball with this hole diameter and hole spacing has greatly improved stability, good elasticity, and greatly reduced deviation distance when flying in the air.

[0027] In test experiment 2, when the distance between adjacent first-layer through holes and adjacent sixth-layer through holes is 12.5+1mm, the distance between adjacent second-layer through holes and adjacent fifth-layer through holes is 13.5+1mm, and the distance between adjacent third-layer through holes and adjacent fourth-layer through holes is 20+1mm, all six balls do not exceed the line.

[0028] In test experiment 3, when the distance between adjacent first-layer through holes and adjacent sixth-layer through holes is 12.5+2mm, the distance between adjacent second-layer through holes and adjacent fifth-layer through holes is 13.5+2mm, and the distance between adjacent third-layer through holes and adjacent fourth-layer through holes is 20+2mm, the two balls are out of line.
