Adjustable test air pipe

An adjustable test air pipe belongs to the technical field of fan coils and comprises a shell, a sampling pipe, a movable panel, a push rod and a plurality of air holes. The shell comprises an upper face, a lower face, side faces, a rear end face and a front end face. The movable panel is arranged in the shell and in front of the movable panel, and an inner cavity of the shell is an adjustable air port; a plurality of scales are marked on the push rod and correspond to the air holes respectively, the front-back position of the movable panel is adjusted through front-back movement of the push rod, and the length of the adjustable air opening is controlled; and the plurality of air holes are symmetrically arranged on the upper and lower surfaces of the shell along the middle line of the length direction. The utility model has the beneficial effects that the time is saved, and the cost is reduced. 一种可调节的测试风管，属于风机盘管技术领域，包括壳体、取样管、可移动面板、推杆、若干风孔；壳体包括上面、下面、侧面、后端面和前端面；可移动面板设置在壳体内，可移动面板的前面、壳体内腔为可调节风口；推杆上标有若干刻度，若干刻度分别与若
