Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a method for attaching and supporting wiring boxes, cables, appliances, etc. by wrapping a stainless steel band around mounting members such as electrical +1, reinforcing bars, and iron fences. Hunt's tightening method and stainless steel band tightening method used in this tightening force method] This invention relates to a working case that accommodates metal fittings and a coil of a stainless steel band.

[Prior Art] Conventionally, it has been known to use stainless steel bands to attach wiring boxes, lamps, indicators, etc. to structures such as telephone poles, reinforcing bars, iron fences, etc.3. Screwless bands are used by tightening them with tightening metal fittings, whereas conventional tightening methods (= 1 metal fittings take time to install and may loosen during use after tightening, and tightening metal fittings are used after band stripes are attached. The terminal of the hunt was deformed by caulking to prevent it from loosening, so when re-tightening the band or removing an item attached to the mounting member, remove the hunt along with the tightening metal fitting and replace it with a new one. [Problems to be Solved by the Invention] In view of the conventional drawbacks, the present invention has a disadvantage in that the band must be replaced when replacing it. At the same time, the stainless steel band can be quickly tightened, the stainless steel band can be tightened without deforming the tightening fitting, the stainless steel band can be tightened without loosening, and the stainless steel band and the tightening fitting can be repeatedly tightened. The object of the present invention is to provide a tightening method and a fastening fitting using a screwless hunt, which can be used easily and simplify the manufacturing and assembly operations of the fastening fitting.

[Effect of the Invention 1] As described in 1iii, the present invention provides a trapezoidal side plate 4.5 through the parallel fold lines 2.3 on both sides of the square base III, and a fold line 6.7 on the outside of the trapezoidal side plate 4.5. Through the folding plate 7.
8, and the rectangular bottom plate 1 is provided with a locking hole 16 for connecting the stainless steel band 40, and the left and right ends of the bottom plate l are provided with diagonal fold lines +7' and corner pieces 28.2 folded back from +8.
Further, cut pieces 26 and 27 are provided at the lower left and right ends of the square bottom plate 1, and upper leg pieces 2+ and 22 are provided protruding from the outside of the upper ends of each of the trapezoidal side plates 4 and 5. Leg plates 10.degree. Lower leg J- on the outside of the lower end of I+! 112 and 13 in a protruding manner, and the straddle plate 25 is continuously provided on the outside of the trapezoidal side plate 4, the fold line 2.3 is first
Bend the trapezoidal side plates 4 and 5 by 90'' and place the stainless steel round bar 30 on the square bottom plate 1 with the small end facing the trapezoidal side plates 4 and 5. Stainless steel round bar 3 by bending 90” towards
0 rolls freely in the direction of the wide mouth part, but the narrow part "1 part a"
It rolls a little in the direction of and then stops midway.

The leg plates 10.11 are located perpendicularly to both ends of the lower narrow opening a of the fastening fitting A, and the lower leg pieces 12. +3 is bent on the surface of part f of the rectangular bottom plate 1. 7 8 It can be bent to reinforce and maintain the box shape of the fastening fitting Δ, and the bent leg pieces 2+ and 22 are made of stainless steel from the wide mouth side. Prevent the round bar 30 from rolling out. Further, since the notch pieces 26, 27 and the corner pieces 2829 protrude from the front side of the rectangular bottom plate 1, the fastening metal fitting A can be stably arranged around the outer periphery of a mounting member such as a utility pole. The work case C has a central cut window 51 in the base plate 50, and a central cut window 5 in the base plate 50.
Since the cut window 53.53a for the washer and the cut window 52.52a for the nut are provided on the lower side of 162, the coil D of the stainless steel band 40 housed in the work case C is inserted into the work case C.
It is convenient to avoid turning the head of the bolt 70 by hand or with a wrench.
Since the tip of 60 protrudes outward from the side of the work case C, it can also be used for similar band tightening fittings such as the band tightening fitting A or the once-richtto band fitting, and can be used for stainless steel bands. The stainless steel band 40 can be temporarily fastened to the tightening fitting Δ while the coil D of the stainless steel band 40 is housed in the work case C, and the tightening work of the stainless steel band 40 can be performed safely, easily and quickly. There is an effect that can be done. .
