TECHNICAL FIELD

[0001] The utility model relates to the technical field of flow guide plate detection fixture, specifically to a kind of flow guide plate detection fixture for automobile air inlet. BACKGROUND

[0002] In order to reduce the lift generated by car when driving at high speed, in addition to the improvement in car shape, the car designer inclines the whole car body to the front and down to generate downward pressure on the front wheel, changes the car tail to short and flat, reduces the negative air pressure from the roof to the rear to prevent the rear wheel from floating, and also installs a downward inclined connecting plate under the bumper at the front end of the car. The connecting plate is integrated with the front apron of the car body, and a suitable air inlet is provided in the middle to increase airflow and reduce air pressure at the bottom of the car. This connecting plate is called a flow guide plate. In order to improve the efficiency of the flow guide plate in use, it needs to be detected before use.

Multiple airflow detectors are fixedly installed at equal intervals on the side walls of the movable seats. The airflow detectors are located between the second fixed plate and the movable block, so that the airflow detectors can fully detect the wind resistance of the guide plate.

[0009] Preferably, a third fixing plate is fixedly installed on the upper end of the base, and a second screw is threadedly connected to the interior of the third fixing plate at equal intervals. The right end of each second screw passes through the interior of the third fixing plate and enters between the third fixing plate and the movable seat.
