Abstract

The present invention relates to an opening/closing mechanism equipped with a self-lock device; the opening/closing mechanism includes a baseplate(1), a fairing(2), a fairing support arm(3), and a powered push cylinder(4); wherein the baseplate(1) is provided with a rotating shaft(5), one end of the fairing support arm(3) is sleeved on the rotating shaft(5), while the other end is connected with the fairing(2) by means of a fairing mounting base(6); the baseplate(1) is provided with a closed-state limit stop(7) and an open-state limit stop(8); a locking device(9) is arranged between the fairing support arm(3) and the powered push cylinder(4), one end of the said locking device(9) can move in the sliding groove of the fairing support arm(3), while the other end is installed on the powered push cylinder(4). The invention is simple and reliable in structure, low in cost, high in stability, and convenient for examination and repair. A power source is used for realization of opening and closing of the opening/closing mechanism, mechanical self-lock is achieved by means of over “dead point” for locking the opening/closing mechanism so as to hold at established state without additional power sources.
