Problems solved by technology

[0004] Generally speaking, the structure of each air gun product is certain, and its firing speed is also certain when it leaves the factory. However, with the use of air guns, its firing speed will be greatly reduced. At present, it is generally through the reduction of shooting accuracy and The reduction of the effective range is used to judge the reduction of its muzzle velocity. There is no speed test device that can be used to quantitatively detect the firing speed.

Abstract

A strength detecting device of eye protector on motorcycle helmet is composed of base ; driving control mechanism, speed generator and release mechanism which are fixed on the base ; speed measuring device set at front end of shooting tube. The device applies unique air seal structure and lead bullet speed can be regulated in certain range so speed of each bullet can be measured to ensure reliability of test data.

Description

Technical field [0001] The invention relates to a detection device, which is used for the strength detection of motorcycle helmet goggles. Background technique [0002] Motorcycles have developed rapidly in my country. In order to ensure the safety of motorcycle drivers and passengers, my country's traffic regulations clearly stipulate that motorcycle drivers and passengers must wear safety helmets when driving and riding motorcycles. Helmet goggles are an important part of the helmet. In the motorcycle inspection project, the technical requirements for the inspection of motorcycle helmet goggles are clearly put forward. The speed impacts the motorcycle helmet goggles to detect whether the strength of the motorcycle helmet goggles meets the requirements. [0003] There are various types of air guns at home and abroad that can be used to launch lead bullets. In order to meet the shooting accuracy at a long distance, most air guns need to consider the shape of the projectile ...
