Background technology
In tennis competition rule, specify: any sportsman, between office and office, has the time of having a rest that is no more than 1 minute; In every innings of match, do not beaten after 6 bulb separations, or deciding game is while changing ends, wipes the sweat with the of short duration time.
One or the one group of doubles sportsman can require once to suspend in bout, and the time is no more than 1 minute.In seven innings of four victory ping-pong contest processed, suppose that you can make seven innings, so altogether in seven innings of matches, can only once suspend chance.
Request suspends only to be made in the time that ball is not in play, should with the hands make "T"-shaped expression.Obtain reasonably and suspend after requirement a side, referee answers suspension and shows person who is not a member of any political party, and then person who is not a member of any political party being placed on claims suspends in the athletic billiard table of side district.
In ping-pong contest, reasonably utilize and suspend, can play the effect of the sensation of destroying the other side.This time, normally when the other side runs, the other side outplays more suitable, calls a timeout timely and the other side's imposing manner can be destroyed, or the other side's tactics are upset in crucial office.
The most employing of current ping-pong contest manually scored.Existing electronic scoring machine is not suitable with ping-pong contest as electronic scorer, and the existing scorer function that all do not clock, when match, needing stopwatch to assist clocks, referee will be placed on sportsman's one side's billiard table of application time-out suspending board in person simultaneously, inconvenient first, second lack science and the fairness of match.
Utility model content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, multiple functional, easy to operate, can effectively improve the multi-functional time-out device for ping-pong contest of on-the-spot judge's operating efficiency.
For solving the problems of the technologies described above, the utility model is to realize like this.
A kind of multi-functional time-out device for ping-pong contest, the display screen vertical drive gear that it comprises support body, base plate, display screen, is furnished with the floor level driven wheel of the second drive motors and is furnished with the first drive motors; The lower vertical of described display screen is fixed with the first tooth bar; In described base plate side, corresponding floor level driven wheel position is laterally provided with the second tooth bar; Described the first tooth bar passes base plate through pilot hole; Described floor level driven wheel is meshed with the second tooth bar; Described display screen vertical drive gear is meshed with the first tooth bar; Described base plate and support body slide and join.
As a kind of preferred version, the utility model can be provided with flexible gasket in described pilot hole.
The utility model drives display screen to carry out two-dimentional compound motion by floor level driven wheel and display screen vertical drive gear, can effectively improve on-the-spot judge's operating efficiency.The utlity model has the features such as simple in structure, multiple functional, easy to operate.
