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 with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0035] The present invention relates to a bidirectional restraining device (referred to as "restraining device") for a large restraining distance of a containerized cargo system of a civil aircraft. It is composed of a positioning shaft, an unlocking tongue torsion spring, a locking tongue torsion spring, a limit rod, a linkage arm, a linkage rod, a compression spring, a base and other mechanisms.

[0036] In view of the demand for two-way stop devices with large restraint spacing (≮100mm) in the containerized cargo system of civil aircraft, and taking into account that the maximum point of the outer contour after the large restraint distance restraint device is unlocked should be lower tha...

Abstract

The invention belongs to the professional field of air cargo, in particular to a bidirectional restraining device capable of realizing a large restraining distance in a containerized cargo system of a civil aircraft. The two-way restraining device includes a locking bolt (1) and an unlocking bolt (4) rotatably connected to the base (7); the locking bolt (1) and the locking bolt torsion spring mounted on the base (7) (11) Contact; the unlocking bolt (4) is provided with an unlocking bolt torsion spring (6); the locking bolt torsion spring (11) and the unlocking bolt torsion spring (6) are respectively used to supply the locking bolt (1) ), the unlocking tongue (4) provides clockwise torque; the unlocking tongue (4) is hinged with one end of the linkage arm (3); the other end of the linkage arm (3) is hinged with the two limit rods (2) ; The two limit rods (2) are rotatably connected with the base (7).

Description

technical field [0001] The invention belongs to the professional field of air cargo, in particular to a bidirectional restraining device capable of realizing a large restraining distance in a containerized cargo system of a civil aircraft. Background technique [0002] The two-way restraint device is matched with the civil aircraft containerized cargo system. It is usually installed in the standard floor slide rail or in the transmission rolling rod mounting frame. , Reasonable two-way limit lock and limit distance can realize the precise locking of the container unit in the loading position required by the freight 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 restraining device, and the highest point of its outline should be lower than the requirement for the height of the system transmission plane. The layout design...
