摘要： An automatic uncoupling mechanism for couplers comprises a coupler knuckle spindle and a driving unit comprising a cylinder body hinged to a coupler body and a telescopic member; and further comprises a first rotating member, a boss and a boss stopper, wherein the first rotating member comprises a crank hinged to the telescopic member and a rotating part being sheathed on the coupler knuckle spindle. The driving unit unidirectionally drives the telescopic member so that the rotating part drives the coupler knuckle spindle to unidirectionally rotate by the contact of the boss with the boss stopper, realizing coupler uncoupling; and, after the driving unit drives the telescopic member to return to its position, the rotation of the coupler knuckle spindle for achieving coupler coupling is not limited by the rotating part. The present application may reduce the lateral force of the coupler knuckle to the driving unit during the uncoupling process of the coupler, and may cause the spring to drive the coupler knuckle to rotate rapidly and lock the coupler during the coupler coupling process.

摘要： 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.
