BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a hanging bolt with a square root when mounting a device or a device disposed under a floor of a vehicle with a hanging bolt with a square root.

[0002]

2. Description of the Related Art When mounting underfloor equipment on a vehicle,
An equipment suspension rail having a T-shaped groove at the lower portion of the underframe is disposed with the opening of the T-shaped groove facing downward or sideward, and a suspension bolt inserted into the T-shaped groove and fixed to the equipment suspension rail. 2. Description of the Related Art There is known a structure in which devices are mounted by using a computer. The suspension bolt in this equipment mounting structure includes a suspension bolt with a square root having a square root at the base end of the shaft portion for preventing rotation and a head having a rectangular cross section following the square root. When the head and the corner root of the suspension bolt are inserted deeply from the opening of the T-shaped groove of the equipment suspension rail to the back of the T-shaped groove and rotated 90 degrees and pulled back, the square root becomes the T-shaped. The groove is fitted between the lips of the opening to prevent rotation, and the head is supported on the inner surface of the lip. Then, the hanging bolt is slid and set in accordance with the device mounting position. Next, insert the shaft of the suspension bolt projecting from the opening of the equipment suspension rail into the bolt hole of the mounting equipment, clamp the washer and tighten the nut, and connect the suspension bolt and the equipment to the equipment. Fasten together to the rail.

At this time, both ends of the head of the suspension bolt extending from the side opposite to the corner root are hooked on the inner surface of the lip of the equipment suspension rail, so that a reaction force for tightening the nut can be obtained. . In addition, since the outer surface of the corner root abuts the opposing surfaces of both lip portions to prevent rotation of the suspension bolt, the nut can be tightened without pressing the suspension bolt head with a spanner or the like. .

[0004]

In such a configuration, when assembling the suspension bolts, the corner roots are once deeply housed in the T-shaped grooves of the equipment suspension rails, and are rotated 90 degrees and then suspended. Since the bolt is pulled back and the square root is engaged between the lip portions, a gap is created between the head of the suspension bolt and the inner surface of the T-shaped groove facing the head of the suspension bolt.

[0005] For this reason, when suspending the equipment, the suspension bolt is pushed in when the suspension bolt is inserted in accordance with the bolt hole of the equipment, or the nut is particularly tightened using an electric tool or the like. At this time, it is easy to push the suspension bolt together with the nut into the T-shaped groove, the square root of the suspension bolt comes out of the gap between the lips into the T-shaped groove, and there is no detent effect, and the suspension bolt rotates together with the nut. For this reason, it has sometimes been difficult to mount the devices.

Accordingly, the present invention provides a mounting structure for a hanging bolt with a square root which can effectively and easily mount various types of equipment in a short time by effectively preventing co-rotation of a bolt with a square root used as a hanging bolt for equipment. It is intended to provide.
