Problems solved by technology

[0010] Purpose of the invention: To provide a two-way restraint device for a large restraint distance in a containerized cargo system of a civil aircraft, which solves the problem that the existing similar restraint device cannot realize two-way locking with a large restraint distance (≮100mm), and cannot be limited in height. The problem of integration with other components of the civil freight system in the space can effectively increase the loading range of different types of container units in the civil containerized freight system, strengthen the integration of the stop device and other freight components, and further improve the safety of the system

Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The invention relates to a two-way restraint device (referred to as "restraint device") for a large restraint distance in a containerized cargo system of a civil aircraft. The restraint device adopts a locking bolt, an unlocking bolt, a bolt Position axis, unlocking deadbolt torsion spring, locking deadbolt torsion spring, limit lever, linkage arm, linkage lever, compression spring, base and other mechanisms.

[0036] Aiming at the demand for a two-way restraint device with a large restraint distance (≮100mm) in the container cargo system of civil aircraft, and taking into account that the highest point of the outer contour after the restraint device with a large restraint distance is un...

Abstract

The invention belongs to the professional field of air freight, and particularly relates to a bidirectional limiting device capable of realizing a large limiting distance in a container type freight system of a civil aircraft. The bidirectional limiting device comprises a locking spring bolt (1) and an unlocking spring bolt (4) which are rotationally connected to a base (7). The locking spring bolt (1) is in contact with a locking spring bolt torsion spring (11) mounted on the base (7). An unlocking spring bolt torsion spring (6) is mounted on the unlocking spring bolt (4). The locking spring bolt torsion spring (11) and the unlocking spring bolt torsion spring (6) are correspondingly used for providing clockwise torque for the locking spring bolt (1) and the unlocking spring bolt (4) respectively. The unlocking spring bolt (4) is hinged to one end of a linkage rotating arm (3). The other end of the linkage rotating arm (3) is hinged to two limiting rods (2). The two limiting rods (2) are rotationally connected with the base (7).

Description

technical field [0001] The invention belongs to the professional field of air cargo, and in particular relates to a two-way restraint device capable of realizing a large restraint distance in a container cargo system of a civil aircraft. Background technique [0002] The two-way restraint device is matched with the container cargo system of civil aircraft, and is usually installed in the standard floor slide rail or the transmission roller installation frame, and is used for reliable restraint in the course or reverse course and vertical direction during the air transport of civil container units , Reasonable two-way stop lock limit spacing, can realize the precise locking of the loading position of the container unit required by the cargo system, and transfer various loads generated by the container unit to the main bearing frame beam of the aircraft through the two-way stop device. [0003] The freight system has an unlocked state for the restraint device, and the highest ...
