A threaded fastener, a fastener arrangement, a fastening track, a cabin floor region, and an aircraft are provided. In order to improve the reusability and operability of a locking device for a threaded fastener (34), such as a threaded bolt (24) or nut (38), a blocking mechanism (48) in combination with the threaded fastener (34) is proposed. The blocking mechanism (48) can be switched back and forth between a blocked state, in which the threaded fastener (34) is engaged in a form-fitting locking manner, and an unblocked state, in which the threaded fastener (34) is engaged in a form-fitting locking manner. In the unblocked state, the threaded fastener (34) may rotate. The blocking mechanism (48) may have a blocking element (50) which, in a blocking state, can engage in a form-fitting locking manner into a blocking groove (54) of the threaded fastener (34), thereby preventing rotation. For example, a nut (38) provided with a blocking mechanism (48) may be used to pivotally fasten the fastening rod (32) to the fastening rail (12).
提供了螺纹紧固件、紧固件装置、紧固轨道、舱室底板区域以及飞行器。为改进用于螺纹紧固件(34)比如螺纹螺栓(24)或螺母(38)的锁定装置的可重复使用性和操作性,提出了一种与螺纹紧固件(34)相结合的阻挡机构(48)。阻挡机构(48)可以在阻挡状态和未阻挡状态之间来回地切换,在阻挡状态中,螺纹紧固件(34)以形状配合式锁定的方式被接合;在未阻挡状态中,螺纹紧固件(34)可以旋转。阻挡机构(48)可以具有阻挡元件(50),阻挡元件(50)在阻挡状态下可以以形状配合式锁定的方式接合到螺纹紧固件(34)的阻挡槽(54)中,从而防止旋转。例如,设置有阻挡机构(48)的螺母(38)可以用于将紧固杆(32)可枢转地紧固到紧固轨道(12)。
