Problems solved by technology
[0003] The starting signal gun in the prior art transmits the signal by striking the chemical starting paper to cause deflagration to generate sound and smoke. The finish timekeeper takes the smoke of the starting gun as a signal and starts timing by the stopwatch, which seriously affects the accuracy of sports competitions at the grassroots level. At the same time, when the wind blows, the air visibility is low, and the quality of the order paper is poor, it will further affect the timing accuracy and increase the timing error.

The invention belongs to the technical field of starting guns, and particularly relates to a starting signal gun. Comprising a starting gun body and a gun barrel. The device is characterized by further comprising a first reminding unit. The first reminding unit is in threaded connection with the gun barrel through threads; a second reminding unit; the starting gun body is a reference; the second reminding unit is arranged above the first reminding unit; a third reminding unit; the third reminding unit is arranged above the second reminding unit; the starting signal gun mainly solves the problems that a starting signal gun transmits a signal by striking chemical starting paper to cause deflagration and generate sound and smoke, a terminal timekeeper starts timing according to a stopwatch when seeing the smoke of the starting gun as a signal, the accuracy of a basic sports competition is seriously influenced, and the starting signal gun cannot be used for starting the starting signal gun when wind blows, the air visibility is low and the quality of the starting paper is poor. The timing accuracy is further influenced, and the timing error is increased.
Description
technical field [0001] The invention belongs to the technical field of starting guns, in particular to a starting signal gun. Background technique [0002] In competitive sports, a device used as a starting signal. The earliest starting gun was a sounding firearm. With the advancement of technology, the starting gun has also been improved. The starting gun is directly connected to the timing system, which can record the results accurately and synchronously. Now the starting signal gun used in the sports field relies on chemical The deflagration of the starting paper produces sound and smoke to transmit the signal. After the starting timekeeper sends out the signal, according to the rules of the competition, it is not allowed to listen to the sound of the gun to count the time. The finish timekeeper must see the smoke coming out before timing according to the watch. However, there are still some problems with the existing starting signal gun, including the following aspects:...
