Standard tube of air inlet flow sensor

The utility model relates to a standard tube of an air inlet flow sensor, which belongs to the field of structural design of engine parts and comprises a standard tube barrel and an air inlet grille. A plurality of barrel bayonets are formed in a pipe opening of the standard pipe barrel, and a plurality of grille chucks clamped and matched with the barrel bayonets are arranged on the periphery of the air inlet grille. The requirement for the assembly angle of the grille and the air inlet pipe barrel (mainly an air inlet flow sensor installed on the barrel) can be met, the reliability of connection and fixation between the grille and the barrel can be ensured, and meanwhile the good assembly manufacturability is achieved. 本实用新型涉及一种进气流量传感器标准管，属于发动机零部件结构设计的领域，其包括标准管筒体和进气格栅；标准管筒体的管口设有多个筒体卡口，进气格栅的外周设有多个与筒体卡口卡接配合的格栅卡头。本实用新型可以确保格栅与进气管筒体(主要是安装在筒体上的进气流量传感器)的装配角度的要求，可以确保格栅与筒体之间的连接固定的可靠性，同时有良好的装配工艺性。
