The invention discloses a self-resetting type speed brake handle structure. The middle of the connecting rod (8) penetrates into the rod sleeve (7), the adjusting anti-rotation block (6) and the spring A (4) to be inserted into the positioning pin A (5), the upper end and the lower end of the spring A (4) abut against the adjusting anti-rotation block (6) and the lower end of the rod sleeve (7) respectively, the rolling mechanism (3) is installed at the lower end of the connecting rod (8), the gear plate (1) is installed on the lower end face of the rod sleeve (7), and the rolling mechanism (3) is clamped into a groove formed in the lower end of the gear plate (1). A positioning pin B (10) is installed at the lower end of the gear plate (1) and makes contact with the limiting mechanism (2). The spoiler has a retraction position, the connecting rod can be reset to the retraction position within the range of-5 degrees to 0 degree, the preset function is achieved, the spoiler is rapidly opened, and potential safety risks are avoided under the emergency situation.

    本发明公开了一种自复位式减速板手柄结构,其中;连杆(8)中部穿入杆套(7)、调节防转块(6)、弹簧A(4)插入定位销A(5),弹簧A(4)上下两端分别抵住调节防转块(6)、杆套(7)下端,连杆(8)下端安装有滚动机构(3),杆套(7)下端面安装有档位板(1),档位板(1)下端设置的槽内卡入滚动机构(3),限位机构(2)上下两端分别连接档位板(1),档位板(1)下端安装有定位销B(10),定位销B(10)与限位机构(2)接触。本发明有缩回位,能满足在‑5°~0°范围内连杆能够复位到缩回位,实现预设功能,扰流板快速打开,在紧急情况下,避免潜在的安全风险。
