Description

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of Chinese Patent Application No. 202322884769.1 filed on Oct. 26, 2023, the contents of which are incorporated herein by reference in their entirety.

FIELD

The present disclosure relates to the technical field of competition scoring devices, in particular to a score board for a competition and a hinge group thereof.

BACKGROUND OF THE INVENTION

Sports competitions not only appear in various large-scale competition sites, but also being spontaneously organized frequently in our daily lives, so as to take actions to practice physical fitness. Proper scoring while following rules during competitions can increase the motivation of each competitor and improve quality of the competitions.

A traditional scoring manner for the competitions mostly uses a simple scoring board, and the scoring board is manually flipped to score. This scoring manner requires personnel to supervise and control scoring throughout a competition during, which takes up too much manpower and is prone to making an error. When large data is recorded, the scoring board needs to be replaced, making an operation more complicated. In addition, a score board used to support the scoring board has a large volume, resulting in a large overall structure, inconvenient carrying and storage, and occupation of a lot of space. Moreover, a traditional scoring device has poor stability. When encountering strong wind blowing on the score board during outdoor use, a support frame will shake, causing the score board to break and affect the scoring of the competitions, and it is also inconvenient to transport and store the score board separately from a bracket.

In view of this, a designer has deeply considered many deficiencies and inconveniences caused by imperfect structure design of an existing competition score board, and actively researched and improved the trial production to develop the present disclosure.
