Description

Technical Field

[0001] The utility model belongs to the field of gas inspection equipment, and particularly relates to a convenient device for gas inspection of an electric bicycle. Background Art

[0002] The main component of gas is methane. For the inspection of gas pipe networks, operators usually carry methane detection instruments such as laser methane analyzers for inspection to avoid accident disasters. Since electric bicycles are small and flexible, at present, electric bicycles equipped with laser methane analyzers have been used to realize the inspection of gas pipe networks, especially those near narrow roads, greatly improving the inspection efficiency. Considering factors such as the difficulty of modifying electric bicycles and the user experience, it is better to install the detection instrument at the bottom of the pedal. However, the current fixation of the detection instrument is relatively conventional. It is simply fixed to the bottom of the pedal directly through multiple bolts, or after fixing a connecting frame at the bottom of the pedal, the whole detection instrument is fixed to the connecting frame through multiple bolts. This method has scattered and trivial operation steps, resulting in inconvenient disassembly and assembly. Content of the Utility Model
