Description

Technical Field

[0001] The utility model relates to the technical field of land curling, and more specifically, to a multifunctional land curling. Background Art

[0002] Land curling, also known as dryland curling, is a throwing sport performed by teams on smooth ground. The goal of winning is achieved by stopping the curling ball in a pre-set position or hitting the opponent's curling ball. Dryland curling is a popular version of curling in the Winter Olympics. The equipment and rules are similar to curling, but the ball is lighter and has three additional pulleys at the bottom for sliding on the ground.

[0003] The sliding wheels in existing land curling are fixedly assembled with the curling body and the sliding shaft, which often makes it impossible to replace the sliding wheels. Forcible replacement will damage the curling body and make it scrapped. Impurities adhere to the sliding wheels during the sliding process and cannot be effectively cleaned, resulting in poor sliding or even stuck, making it impossible to slide, and causing the curling to be scrapped.

[0004] A Chinese patent application with patent number CN202123344640.9 discloses a land curling stone to solve the problems in the prior art that the sliding wheel, the curling stone body and the sliding shaft are fixedly assembled, and the sliding wheel cannot be replaced or replaced by force, which will cause the curling stone body to be damaged and scrapped, and impurities in the sliding wheel during sliding cannot be effectively cleaned, resulting in poor sliding or even stuck, and the curling stone cannot be scrapped, and the curling stone has a short service life and a high cost of use. The device includes a main body, a connecting piece and a sliding assembly, wherein the sliding assembly includes a fixed seat, a ball and a cap, the ball is arranged between the fixed seat and the cap, and the cap is detachably connected to the fixed seat; a accommodating cavity is arranged inside the main body, the fixed seat is located inside the accommodating cavity, and the connecting piece extends into the accommodating cavity and is detachably connected to the fixed seat;

[0005] Then, combined with the drawings in the specification, it can be seen that the ball is limited between the ball position cap and the fixed seat. When dust adheres to the surface of the ball, it will affect the smoothness of the ball's rotation, thereby affecting the smoothness of the movement of the curling stone, and affecting the moving direction and distance of the curling stone.
