Description

[Detailed Description of the Invention] When supplying water or sprinkling water by connecting a long hose to a faucet, if the hose twists and breaks in the middle, the water pressure inside the hose increases and the connection with the faucet or the connection between the hoses increases. These connections are tightened with bands because the parts will come off.

By the way, there are various types of conventional fastening bands, but many of them produce wrinkles or folds on the surface of the hose when tightened, causing water leakage from these areas, or are complicated and troublesome to tighten.

This invention solves the above-mentioned problems of conventional fastening bands for hose connections, and its purpose is to provide a hose connection that is easy to tighten without causing wrinkles or folds in the hose when tightening. There is a fastening band for use.

The details of the invention will be explained below based on embodiments shown in the accompanying drawings.

In FIGS. 1 and 2, 1 is a band body, and 2 is a fastening nut. .

In the band body 1, a narrow band section 12 is connected to the tip of a wide band section 11, and an elongated hole 13 is formed over the entire length of the wide band section 11 through which the small band section 11 passes.

In addition, nuts 2 are provided on both side edges of the small and medium band portion 12.
There are projections and depressions 14 that serve as external threads for screwing.

At the rear end of the wide band section 11, a receiving section 15 that contacts the circumferential surface of the hose protrudes from the back surface in order to flatten the rear end from the hose surface, and at the rear end there is a small 111 band section. A hole 16 is formed through which the hole 12 is passed.

This invention is as described above, and this fastening band for a hose connection part consists of a band main body and a fastening nut, and the band main body connects a small [1] band part to the tip of a wide band part, The wide band part has an elongated hole through which the small and medium band parts pass, and a small [1] hole is formed on both edges of the front side of the band part for the purpose of a male screw. Since it has a hole for passing the band through, for example, when the hose 4 is connected to the faucet 3 as shown in Fig. 3, this fastening band A is attached to the end of the hose that is placed over the faucet. With the nut 2 removed, wrap the wide [1] band part 11 of the band body 1 around the hose 4, then pass the narrow band part 12 through the long FL13, wrap this small and medium band part also around the hose, and then wrap it around the hose. The tip is passed through the hole 16 at the rear end of the wide band section, and the nut 2 is screwed in.

Then, the narrow band portion 12 overlapping the wide band portion 11 is
Where the elongated hole 13 exists, it fits into the elongated hole and is on the same surface as the wide band part, and is double wound, so even when the nut is tightened, the wide band part holds the hose and the narrow band part does not hold the hose. Only the band portion is attracted to the nut side within the elongated hole 13, and there is an effect that there is no fear of wrinkles or folds occurring on the circumferential surface of the hose during fastening, unlike in conventional fastening bands.

Also, on the back side of the rear end of the wide band part, there is formed a receiving part 15 that lifts this rear end from the circumferential surface of the hose, so even if the nut 2 pulls the narrow band part, the rear end of the wide band part will not float up. Therefore, the nut tightening operation becomes extremely easy.
Moreover, there is an effect that the tightening operation of the nut becomes smooth.

By making the receiving part 15 successively protrude from the rear end of the long hole 13 as shown in the figure, the rear end plate part of the wide band part and the small and medium band part passed through the hole in this part can be made to intersect at a nearly right angle. By making the receiving surface 3 of the receiving part 15 curved in an arc shape, the right-angled intersecting state will not be disrupted even when the nut is tightened, and the nut tightening operation can be made even smoother. can.

This fastening band is obtained by punching out a metal plate and the receiving part 15 is bent, but the receiving part 15 can be made thick by using a strong synthetic resin such as polyethylene or nylon. It is also possible to increase the wall thickness of the concave and convex portions 14 that serve as male threads in the small and medium band portions.
