The embodiment of the invention discloses a locking structure and a horizontal stabilizer trim actuator, the locking structure is applied to the horizontal stabilizer trim actuator, and the horizontal stabilizer trim actuator comprises a hollow rolling screw rod. The locking structure comprises a locking rod and a connector. The locking rod is provided with a first rod and a second rod which are connected, the first rod is used for being arranged in the rolling lead screw in a penetrating mode and fixedly connected with the rolling lead screw, and the second rod is used for penetrating out of the rolling lead screw. The connector comprises a limiting shell, and the limiting shell is arranged on the second rod in a sleeving mode and connected with the second rod in a sliding mode. A plurality of limiting groove sets are formed in the second rod at intervals in the axial direction of the locking rod, safety positions are formed in the intervals between the adjacent limiting groove sets, limiting notches are formed in the peripheral wall of the limiting shell, limiting blocks are arranged in the limiting notches, and when the second rod rotates, the projection of the limiting blocks on the second rod is overlapped with the safety positions. When the second rod slides in the axial direction of the locking rod, the limiting block is embedded in the limiting groove set.

    本发明的实施例公开了一种锁止结构及水平安定面配平作动器,其中锁止结构应用于水平安定面配平作动器中,水平安定面配平作动器包括中空的滚动丝杆。锁止结构包括锁止杆和接头。锁止杆具有相连接的第一杆和第二杆,第一杆用于穿设于滚动丝杆中,与滚动丝杆固定连接,第二杆用于穿出滚动丝杆。接头包括限位壳,限位壳套设于第二杆上,与第二杆滑动连接。其中,沿锁止杆的轴向,第二杆上间隔开设有多组限位槽组,相邻限位槽组之间的间隔处形成有安全位,限位壳的外周壁上开设有限位缺口,限位缺口中具有限位块,在第二杆转动时,限位块在第二杆上的投影与安全位重叠,在第二杆沿锁止杆的轴向滑动时,限位块嵌设于限位槽组中。
