OPENING/CLOSING MECHANISM HAVING A SELF-LOCKING DEVICE

摘要

An opening/closing mechanism having a self-locking device, the opening/closing mechanism comprising a bottom plate (1), a fairing (2), a fairing support arm (3), and a power source push cylinder (4); the bottom plate (1) is provided with a rotating shaft (5), one end of the fairing support arm (3) is sleeved on the rotating shaft (5), and the other end is connected to the fairing (2) by means of a fairing mount (6); the fairing (2) is provided with a closed-state limit stop (7), and an open-state limit stop (8) is arranged between the fairing support arm (3) and the fairing mount (6); a locking device (9) is arranged between the fairing support arm (3) and the power source push cylinder (4), one end of said locking device (9) can move within the sliding groove of the fairing support arm (3), and the other end is mounted on the power source push cylinder (4). The opening/closing mechanism has a simple and reliable structure, is low cost and highly stable, and is easy to maintain; a power source is used for opening and closing the opening/closing mechanism and mechanical self-locking is achieved by means of "dead points"; locking the opening/closing mechanism holds same in a given state without requiring an additional power source.
