This idea was created in view of the above points, and focused on the fact that the top surface of the rail fixing clip is an arcuate surface, and uses this arcuate surface and the bolt insertion hole to prevent loosening IE. The purpose of the present invention is to provide a device that can effectively prevent loosening by applying simple processing to the tightening surfaces of bolts and nuts.

以下、この考案の実施例を添付図面に基づいて説明する
Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The locking device of this invention has a bolt 1, a nut 2, and an elongated hole through which the shaft of the bolt is inserted in an arcuate surface, and a clip 6 that elastically fixes the object by tightening the bolt 1 and nut 2. In the tightening seat surface of the bolt 1 or nut 2, a recessed groove 3 is formed along the direction intersecting the axis from both sides of the outer circumference and deepens toward the solid axis. Projecting step portions 4, 4 on both sides along the groove direction
It is configured with the following.

That is, the tightening seat surface of the nut 2 is lowest on both sides due to the formation of the recess 3, and in order for the nut 2 to rotate in the loosening direction, the lowest portions on both sides must pass the top of the clip 6. First, since the pressure contact elasticity of the clip 6 is always acting, the first loosening prevention occurs due to the pressure contact between the recess 3 and the upper surface of the clip 6.

Although the protruding step portions 4, 4 in the first example are formed by right-angled surfaces, they may be formed by inclined surfaces 4a as in the second example shown in FIGS. 6 and 7. With such an inclined surface 4a, when tightening the nut 2, the protruding step portions 4, 4 can be smoothly placed back on the upper side edge 7a of the elongated hole 7,
Tightening work becomes easier.

As shown in FIG. 1, the nut 2 is screwed into the anchor bolt 8 passing through the elongated hole 7 of the clip 6 and tightened. When the predetermined tightening force is reached, the recess 3 is aligned with the arcuate surface of the clip 6. When the recess 3 and the clip 6 are pressed against each other, a first loosening mechanism is generated, and the protruding step portions 4 and 6 on both sides are prevented from loosening.
4 fits into the elongated hole 7 and engages with the upper side edge 7a of the elongated hole 7, thereby creating a second locking mechanism.

As mentioned above, according to this invention, bolts, nuts,
The arc-shaped surface is provided with a long hole through which the shaft of the bolt is inserted, and the clip elastically fixes the fixed object by tightening the bolt or nut. A recess is formed in the intersecting direction, and a protruding step is provided on both sides of the recess along the groove direction to engage the elongated hole of the clip, so that the recess comes into pressure contact with the object to be tightened when the bolt or nut is tightened. At the same time, since the protruding step engages with the side edge of the bolt insertion hole and groove, the locking effect is also generated in this part, and the synergistic effect of both locking mechanisms prevents bolts and nuts from tightening. Effective loosening correction can be obtained only by tightening.

また、ボルト、ナツトには締付面側に凹部と突出段部を
設けるだけでよいので、加工が容易であり、座金や別体
の緩み火手段を必要としないので、コスト的に廉価であ
り、多数を使用する場合も経済的である。
In addition, since bolts and nuts only need to be provided with a recess and a protruding step on the tightening surface side, processing is easy, and there is no need for washers or separate loosening means, so the cost is low. , it is also economical to use a large number of them.

さらに、ボルト、ナツトは、両側の突出段部がクリップ
の長孔に掛合するので、ボルトの軸部は長孔の幅方向中
央部に保持され、ボルト軸部とクリップの接触が防止さ

ず、破損するようなこともない。
Furthermore, since the protruding step portions on both sides of the bolt and nut engage with the elongated hole of the clip, the bolt shaft is held in the center of the elongated hole in the width direction, and contact between the bolt shaft and the clip is prevented. No excessive force is applied to the threads of bolts or nuts, and no damage occurs.

さらに、ボルト、ナツトを単にねじ込むだけで緩み正が
得られるので、締付作業が容易で能率よく行なえ、作業
コストの削減を計ることができる。
Furthermore, since loosening can be corrected by simply screwing in bolts and nuts, tightening work is easy and efficient, and work costs can be reduced.
