Quick install nut

A quick install nut comprising:

• a main body including a first threaded portion in the form of a sleeve and a tightening wall with a tightening surface;
• the main body further provided with a first side and a second side opposite to each other;
• the first threaded portion composed of a first entrance end connected to the tightening wall, a first exit end, a first threaded slot defined in the first threaded portion, and a first internal thread which is disposed on a part of an inner surface of the first threaded slot, located at the first side, and distributed in a circumferential direction;
• and
• a movable member pivotally connected to the tightening wall of the main body at the second side and rotatable between an open position and a closed position;
• the movable member having a second threaded portion in the form of a curved block and a resisting wall provided with a resisting surface;
• the second threaded portion provided with a second entrance end connected to the resisting wall, a second exit end, a second threaded slot defined in the second threaded portion, and a second internal thread which is formed at a part of an inner surface of the second threaded slot, located opposite to the first internal thread, and distributed in a circumferential direction;
• wherein the resisting surface of the movable member is at a level higher than a level of the tightening surface of the main body and the second internal thread is swinging away from the first internal thread when the movable member is in the open position;
• thus a threaded fastener in disengaged state is allowed to be quickly inserted through a space between the first internal thread and the second internal thread axially along the main body;
• the resisting surface of the movable member is pressed so that the movable member is pivotally rotated from the open position to the closed position and the second internal thread is forced to swing toward the first internal thread at the same time;
• thus both the first internal thread and the second internal thread are engaged with an external thread of the threaded fastener.
