the upper shell 11 is internally provided with a first cavity 112, the first cavity 112 is rotatably provided with large balls 2, the large balls 2 are used for driving the tabletop curling ball to slide through inertia, the upper shell 11 and the lower shell 12 are matched to form at least three second cavities 113, the second cavities 113 are rotatably provided with small balls 3, the small balls 3 are distributed at equal intervals along the circumference of the large balls 2, the small balls 3 are used for enabling the tabletop curling ball to generate arc balls by rotating around the large balls 2, the interestingness and the sports of the tabletop curling ball are increased, the large balls 2 and the small balls 3 are suitable for suspending the lower shell 12 in the air, the friction between the lower shell 12 and the ground or a table top is avoided, the sliding distance and the smoothness of the tabletop curling ball are increased, a plurality of bearing balls 4 are arranged between the small balls 3 and the upper shell 11, the lower shell 12 is provided with a limiting part 121, the limiting part 121 is suitable for matching with the small balls 3 to prevent the bearing balls 4 from being separated from the second cavities 113, traditional bearing structure has been cancelled, has got rid of the bearing dead weight and has reduced the installation degree of difficulty to the gliding influence of desktop curling ball, because spacing portion 121 and lower casing 12 integrated into one piece, structural strength is also higher, difficult emergence damage.

The weight ratio of the large ball 2 to the shell 1 is alpha, alpha is more than or equal to 7 and less than or equal to 8, the larger the specific gravity of the large ball 2 and the shell 1 is, the more flexible the table curling ball is, and the inertia is used for pushing the curling to move.

The body shapes of the first cavity 112 and the second cavity 113 are approximately spherical.

The movable gap beta is formed between the large ball 2 and the first cavity 112, beta is not less than 0.3mm and not more than 0.65mm, the stability of the large ball 2 in the rotating process can be improved, the sliding distance of the curling ball on the table is increased, the large ball 2 and the first cavity 112 are collided due to the overlarge movable gap beta, the large ball 2 and the first cavity 112 are rubbed due to the undersize movable gap beta, and the sliding distance of the curling ball on the table can be reduced.

As shown in figure 5, a movable gap gamma is formed between the small ball 3 and the bearing ball 4, wherein gamma is more than or equal to 0.05mm and less than or equal to 0.1mm, the rotating stability of the small ball 3 can be improved, if the movable gap gamma is too small, the bearing ball 4 is difficult to rotate, and if the movable gap gamma is too large, the bearing ball 4 is stacked and collided, so that the sliding effect of the curling ball on the table is influenced.

The smoother the outer surface of upper housing 11, the better, the material of upper housing 11 is preferably polytetrafluoroethylene.

The lower shell 12 has wear-resistant property, so that the lower shell 12 is prevented from being excessively worn on the ground or a table top to cause unbalanced weight and even damage, and polyformaldehyde is preferably used as the material of the lower shell 12.

As shown in fig. 2, the upper housing 11 includes a first sub-housing 114 and a second sub-housing 115, the first sub-housing 114 and the second sub-housing 115 are clamped, the handle 111 is integrally connected to the top of the first sub-housing 114, and the second sub-housing 115 and the lower housing 12 cooperate to form the second cavity 113.

As shown in fig. 4, a first fixing ring 1141 is disposed around the first sub-housing 114, a second fixing ring 1151 is disposed around the second sub-housing 115, and the first fixing ring 1141 is suitable for being engaged with the second fixing ring 1151, so as to improve the strength of the connection structure between the first sub-housing 114 and the second sub-housing 115.

Limiting channels 1152 are formed in the second sub-shell 115, connecting columns 1142 are formed in the first sub-shell 114, connecting grooves 122 are formed in the lower shell 12, the connecting columns 1142 and the connecting grooves 122 are respectively nested at two ends of the limiting channels 1152, threaded fasteners 5 are arranged in the connecting grooves 122 and connected with the connecting columns 1142, the connecting forms of the fasteners are clamped and nested, the connecting stability among the shells is increased as much as possible, and structural deformation is avoided.

As shown in fig. 2, the equidistant interval setting of threaded fastener 5 and little ball 3 can promote threaded fastener 5 to the stability of being connected between last casing 11 and the lower casing 12, makes the structure atress of second cavity 113 more even, is difficult to the deformation damage, leads to little ball 3 to break away from.

The mounting process of the ice kettle ball on the table is as follows: the first sub-shell 114 is turned over, the large ball 2 is embedded into the first cavity 112 on the first sub-shell 114, the second sub-shell 115 is clamped on the first sub-shell 114, then the bearing ball 4 is placed into the second cavity 113 on the second sub-shell 115, the small ball 3 is embedded into the second cavity 113, the lower shell 12 is clamped on the second sub-shell 115, and finally the threaded fastener 5 is installed, so that the whole installation process can be completed.

The foregoing has described the general principles, essential features, and advantages of the application.
