Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a steel plate band for trapping objects such as equipment and metal fittings to pillars and the like.

(Prior art) As shown in Fig. 4, a conventional steel plate band has a supporting solid rod at one end of a narrow steel plate band.
A rod C is loosely passed through this support solid L, a tightening nut is screwed onto the threaded part at one end of the rod C, and the band is provided with a large number of through holes, and the band is inserted into the desired covering. The rod was wound around an object to be captured, and the key at the other end of the rod was hooked into one of the many through holes at the other end of the bandoy, and the tightening nut was turned to tighten the bandoy.

(Problem to be solved by the invention) In this conventional device, the rod C loosely penetrates the support solid B at one end of the band, and when the tightening nut is turned, the rod C slides only in a fixed direction. . Therefore, depending on the diameter of the object to be captured with this bandoy, the key part of the rod C may not fit into the through hole at the other end of the bandoy, making it impossible or difficult to lock the object. Furthermore, depending on the diameter of the object to be secured, the sliding direction of the rod C due to the tightening rotation of the tightening nut may differ from the winding direction of the bandoy, making it easy for the key to come out from the through hole H. For these reasons, there is a drawback that the workability of tightening the steel plate band is poor.

(Means for solving the problem) Therefore, this invention solves the above problem by making the key part at the tip of the rod loosely penetrating the supporting solid provided at one end of the band rotatable with respect to the rod. It is something to be solved.

In this specific configuration, one end of the rotating body is rotatably supported at one end of the rod, and a downward protrusion is provided at the other end of the rotating body between the key piece and the other end of the rotating body. It is something.

(Function) Wrap this device around an object to be captured, overlap both ends of the band, rotate the rotary body at the tip of the rod protruding from one end of the band, and rotate the key piece at the tip of the band at the other end of the band. Hook it into one of the holes and turn the tightening nut. As a result, the rotating body at the tip of the rod is pulled toward the support solid. Therefore, the band becomes shorter and tightens the object to be captured. At this time, the lower end of the protrusion of the rotating body pushes the band, and the lower end of the protrusion serves as a fulcrum to stably pull the key piece.

(Example) An example of this invention will be described below with reference to the drawings.

Reference numeral 1 denotes a band made of a steel plate with a large number of through holes 2 provided from one end to the other, 3 a support frame with a quadrilateral cross section provided at one end of this band 1, and 4 a pair of opposed support frames 3. Holes 5 are drilled in the side plate of , and threaded rods 5 are passed through these holes 4, and when the band 1 is stretched flat, this screw rod 5
The support frame 3 is supported parallel to the support frame 3 and is slidable along the hole 4 of the support frame 3. 6 is a tightening nut screwed onto one end of a threaded rod 5 protruding toward the band 1 side, and 7 is a rotating body whose one end is pivotally supported by a pin 8 on the other end of this threaded rod 5; It has a triangular shape and has a key piece 9 at the other end opposite to the shaft support where the pin 8 is located, and furthermore, the corner that hangs downward between the pin 8 and the key piece 9 forms a protrusion 10. ing.

In this embodiment, the band 1 is wound around the object to be captured, and both ends of the band 1 are overlapped with the support frame 3 facing upward, and a threaded rod 5 protruding from the support frame 3 is placed on top of each other.
Rotate the rotating body 7 at the tip of the pin 8 as an axis,
Hook the end key piece 9 into an appropriate hole 2 of the band 1, and turn the tightening nut 6. As a result, the threaded rod 5 is pulled from right to left in FIG. 3, and the rotating body 7 is also pulled leftward accordingly. Then, both ends of the band 1 are tightened in the direction of overlapping each other, but when they are not tightened any further, the tension acts on the rotating body 7 to rotate it in the counterclockwise direction in FIG. 3 about the pin 8.
This causes the protrusion 10 to push the band 1 below.
The lower end of the protrusion 10 serves as a fulcrum, and the key piece 9 is pulled stably and firmly locked to the periphery of the through hole 2 of the band 1.

In this embodiment, a rotating body 7 is provided at the tip of the threaded rod 5.
However, the present invention is not limited to this, and a threaded portion for screwing a tightening nut may be provided at one end of the rod, and a rotating body may be pivotally supported at the other end of the rod. Further, the support frame 3 is not limited to this, and may be any suitable support solid as long as it supports a threaded rod or a rod.

(Effects of the invention) This invention has the above-mentioned configuration, and when tightening an object with a band, the key piece that protrudes from one end of the band is provided at one end of the rotating body that can freely rotate with respect to the rod. Therefore, the angle with respect to the rod can be changed arbitrarily, and even if the object to be caught has a variety of diameters, it can be easily hooked into the hole at the other end of the band. Moreover, the protrusion located below between the key piece and the shaft support of the rotating body hits the band, and this protrusion serves as a fulcrum to stably lock the key piece to the periphery of the through hole and tighten it. By tightening and rotating the nut, the tensile force of the rod is easily changed direction by the protrusion of the rotating body and transmitted to the key piece, and the key piece is firmly locked to the periphery of the hole. Therefore, unlike conventional devices, it is not difficult to insert the key piece into the hole depending on the diameter of the object to be captured, or it is easy to remove the key piece even if it is inserted, and the tightening force of the band is also strong.
