The stopper 3 is provided with a screw hole or a straight hole 6 at least at one place, and at least one end of the support 1 is fixed with the inserted stopper 3.
A fitting groove 4 for receiving the tip of a bolt 7 screwed or fitted into a screw hole or a straight hole 6 of the stopper 3 is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support tool used for supporting a shackle, a float, a fastening tool, and the like.

[0002]

[Prior Art]

 Conventionally, for example, bolts and nuts have been used as typical shackle, float, and tightening support devices.

[0003]

[Problems to be solved by the device]

 However, when bolts and nuts are used to support the nuts in recent years, there are many accidents where the nuts come loose and fall off. This phenomenon occurs because the bolt or nut itself rotates in the direction to loosen the nut due to vibration, etc. Even if it is locked with a pin to prevent loosening of the nut, the pin may break due to the rotation of the nut. Was occurring. In addition, loosening the nut often crushed the screw of the bolt and lost bearing capacity at all.

[0004]

[Means for Solving the Problems]

 As a result of various studies to solve these conventional drawbacks, the present inventor inserts a stopper into at least one end of the support, and provides the stopper with a screw hole or a straight hole at at least one position. We have completed a support tool that has a fitting groove at the end of the support that fits the tip of a bolt that passes through the screw hole of the stopper. In addition, since a stopper that is about the same size as the nut is stopped by the stopper, it is held down by the side of the nut and the screw fastener, so unlike the conventional stopper that uses only a pin, the stopper does not receive the force of screw rotation.

Next, the support of the present invention will be described with reference to the drawings, but the present invention is not limited to the following description. FIG. 1 is a side view of the support body 1. A bolt head 2 is provided at one end and a fitting groove 4 for fixing a stopper 3 is provided at the other end. It is preferable to provide a plurality of the fitting grooves on the support 1 as shown in FIG.

As shown in FIG. 3, the stopper 3 to be inserted into the support 1 has a hexagonal outer side like a conventional nut, and has a hole 5 at the center thereof into which the support 1 can be inserted. It The stopper 3 is provided with a screw hole or a straight hole 6 so that a bolt can be inserted. At least one screw hole or straight hole 6 may be provided, but FIG. 3 shows the case where three holes are provided.

FIG. 4 is a partially enlarged view when the stopper 3 is attached to the support body 1. The support body 1 is inserted through the hole 5 of the stopper 3 and the fitting groove 4 formed in the support body is bolted. The bolt 7 is fixed at a position where the bolt is inserted, and the bolt 7 is screwed into the fitting groove 4 so that the tip end of the bolt 7 fits into the fitting groove 4 and the tightening is completed.

The support of the present invention may be fixed to the support 1 by using one stopper 3 as described above, but two or more may be used. In this case, there must be as many fitting grooves as the number of stoppers, where bolts are inserted and fixed in the screw holes or straight holes of each stopper.

FIG. 5 is a front view when the support of the present invention is used for the shackle 8. That is, the support 1 of the support is inserted into the insertion openings 9, 9 of the shackle 8. This support is of a type having a bolt head 2 at one end of a support and a stopper attached at the other end. The support tool inserted so as to pass through the insertion ports 9, 9 of the shackle 8 is supported by inserting the stopper 3 into one end of the support 1 and screwing the bolt into the screw hole or the straight hole 6 of the stopper 3. The front end of the bolt 7 can be fixed in a fitting groove 4 provided in the body 1 in a fitted state. The fitting groove 4 provided in the support body 1 must be provided in a position where the size of the stopper, the position of the screw hole or the straight hole, etc. are measured in advance and the bolt 7 is just fitted when it is screwed in. Not to mention is a matter of course.

As shown in FIG. 6, for example, the support of the present invention is provided with screw grooves 11 for inserting nuts at both ends of the support 1 when it is used for fixing the float 10. A fitting groove 4 for fixing the bolt inserted in the stopper 3 is provided on the outside.

When the float 10 is fixed using such a support tool, the float 1 is fixed in a tight state by inserting the support 1 into the float 10 and inserting nuts 12 from both ends and tightening. You can In order to adjust the degree of the tightened state, it is determined by selecting the position of the thread groove 11 provided in the support 1. After fixing the nut 12, the stopper 3 is inserted, and the bolt is inserted into the screw hole or the straight hole 6 and tightened, so that the tip of the bolt enters the fitting groove and is fixed. By fixing both ends of the float as described above, the support and the float 10 are integrated.

In the present invention, for example, the rotation of the stopper 3 can be prevented by making the cross-sectional shape of the support 1 at least until the stopper 3 is inserted into a polygon such as a triangle or a quadrangle, or an ellipse. preferable.

[0013]

[Effect of the device]

 In the support of the present invention, unlike the conventional bolts and nuts, a stopper is simply inserted without tightening with screws, and the tip of the bolt is attached to the support 1 from the direction of 90 ° with the support 1. Since it is fixed so that it fits in the dowel groove 4, the stopper will not loosen even at the time of a slight earthquake.
