The invention relates to an adaptive adapter device for a lifeboat throwing system, the device is composed of a ball upper snap ring (1), a ball lower snap ring (2), a nylon ball (3) and a split washer (4). Determine the position where the connecting steel cable passes through the side wall of the ship box according to the installation position of the lifeboat inflatable gas cylinder and the adapter, and attach the upper ball snap ring (1) and the lower ball snap ring (2) to the back to form a circle in the middle. The spherical hole whose diameter corresponds to the nylon ball (3), clamp the nylon ball (3) inside the adapter device, and connect the adapter device with the four corners of the ball upper snap ring (1) and the ball lower snap ring (2) through the bolt holes The side wall of the ship box is fixed, the split washer (4) is installed in the groove inside the nylon ball (3), the connecting steel cable is passed through the inner through hole of the nylon ball (3), and is blocked by the split washer (4). The invention has the advantages that the structure and specification of the ball upper snap ring 1 and the ball lower snap ring 2 are exactly the same, which reduces the processing cost and facilitates installation.
Description
technical field [0001] Transport aircraft emergency evacuation system Background technique [0002] In the design of the normal steel cable passing through the partition, only holes are punched on the partition, and a simple through-hole wear-resistant design is carried out, and generally there is no special transfer device. During the flight of the aircraft, the simple design of the through hole will cause the vibration of the aircraft, which will cause the sway of the cable in the lifeboat throwing device, and the sway of the cable connected between the inflatable gas cylinder of the lifeboat and the pin puller may cause the decompression valve in the gas cylinder to sway. The movement or dragging of the lifeboat will affect the reliability of the lifeboat discharge. Contents of the invention [0003] The purpose of this invention is to design an adapter device with simple structure and easy installation, which can fix the connection cable between the inflatable gas cyl...
