Embodiment Construction
[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0015] A rotating lifesaving box cover locking mechanism is symmetrically installed at both ends of the seat front beam. The mechanism includes a cushion limiting box (1), a rotating groove (2), and a torsion spring (3);
[0016] The pad limiting box (1) is a half-shaped structure, and an inverted L-shaped groove is opened on the back side of the half-shaped structure;
[0017] The rotating groove (2) includes a U-shaped groove body, and concentric shafts are respectively arranged along the two ends of the groove body in the axial direction. position, and the direction of the concentric axis is parallel to the long side direction of the half-shaped structure, and the rotating groove can rotate around the concentric axis;
[0018] The torsion spring (3) is installed on the concentric shaft, and the rotation of the rotating groove (2) is restricted by the pre...

The invention discloses rotary lifesaving box cover locking mechanisms and belongs to the field of aviation ejection lifesaving. The rotary lifesaving box cover locking mechanisms are symmetrically mounted at the two ends of a front beam of a seat. Each rotary lifesaving box cover locking mechanism comprises a limit cushion box (1), a rotating groove (2) and a torsion spring (3), wherein the rotating groove (2) is mounted inside the limit cushion box (1) which is of a semi-I-shaped structure; the rotating groove (2) is capable of rotating around the axis direction parallel to the long side ofthe limit cushion box (1); the action of the pre-tightening force of the torsion spring (3) ensures that the opening of the rotating groove (2) faces upwards without external force; the front end of arotating shaft (7) of a lifesaving box cover is restricted in the rotating groove (2) due to the self weight of the lifesaving box cover (5) so that the operation is convenient; and when a separationsystem works, the lifesaving box cover (5) slides off along the rotating groove at a fixed angle after driving the rotating groove (2) to rotate to the upper end surface of the limit cushion box (1),so that the reliability is high. The rotary lifesaving box cover locking mechanisms facilitate the popularization and application and have great practical value.
Description
technical field [0001] The invention discloses a rotary lifesaving box cover locking mechanism, which belongs to the field of aviation ejection lifesaving, and in particular relates to a rotary lifesaving box cover locking mechanism. Background technique [0002] The existing rescue kits for rocket ejection seats are divided into semi-rigid packs and hard packs. In order to ensure the smooth separation of the rescue box cover and the seat pan, the limit of the life-saving box cover in the seat pan with the hard pack is limited by a cushion box and a rotating shaft. And the fuse limit, and after the separation system works, the safety is broken by the seat's own weight to realize the separation of people and chairs. This limiting method has poor fault tolerance and complicated operation, which is not conducive to the maintenance of the seat. Contents of the invention [0003] The purpose of the present invention is to provide a rotary lifesaving lid locking mechanism that ...
