Description

[Detailed Description of the Invention] The present invention relates to a hose connection band, and more particularly to a hose connection band that allows a hose to be connected to a metal fitting without using any special tools.

Conventionally, when connecting a hose to a metal fitting using a hose connection band, a tool is required in many cases, and the user has to use the tool every time to connect the hose, which is a hassle. Particularly at civil engineering construction sites, suitable tools are often not available, and in the case of conventional hose connection bands that use tools, it takes time to connect the hoses, so tool tightening bands are not used at present.

The present invention was devised in view of the above-mentioned circumstances, with the purpose of providing a hose connection band that does not require tools.

Therefore, according to the present invention, a metal wire such as an iron wire or a copper wire is bent into a figure 8 shape, the joints of each loop formed by bending into the figure 8 shape are twisted, and the ends of the metal wire are soldered. Combined by attaching etc. to form an endless figure-eight band, one loop of the figure-eight band serves as a hose tightening part and the other loop serves as a twisting part, all or all of the loops serving as the twisting part. A hose connection band is provided in which a portion of the band is made weaker in strength than a loop serving as a hose tightening portion and is provided with a cutting portion.

In this way, in this invention, in addition to the loop that serves as the hose tightening section, a loop that serves as the twisting section is integrally provided with the loop that serves as the hose tightening section, so that the hose can be attached to the fitting using this connection band. When making a connection, you can insert a suitable rod into the loop of the torsion part and twist it without preparing a separate tool, and the loop of the hose clamping part will be tightened, allowing you to connect the hose to the fitting. Since all or part of the loop that becomes the hose tightening section is made weaker than the loop that becomes the hose tightening section and has a cut section, it is necessary to avoid applying excessive twisting force after tightening the loop of the hose tightening section. The loop of the torsion part is cut from the loop of the tightening part, and no tools are required for cutting.Furthermore, it can be manufactured by simply bending a metal wire into a figure 8 shape, and can be provided at low cost.

Embodiments of the present invention will be described below with reference to the drawings.

Metal wires such as iron wires and copper wires 1 in Figure 1 A and B
A small diameter loop 2 and a large diameter loop 3 are formed by folding into a figure 8 shape.
Twist the joint 4 with the In this embodiment, it is twisted once, but it may be twisted several times. Then, the ends 5 and 6 of the metal wire 1 are joined by soldering 7 or the like to form an endless figure-eight band C, one loop 3 of the band C is used as a hose tightening part, and the other loop 2 is twisted. Department. In this embodiment, the loop is single at the twist section and double at the hose tightening section.

There is a weak part near the joint 4 of the loop 2, which becomes the torsion part, for example, a notch 8 as shown in FIG.
If a twisting force more than necessary is applied to the notch 8, the metal wire 1 will be cut off at the notch 8. In addition, instead of forming a notch, the material of the loop 2 which becomes the twisting part is made weaker than the material of the loop 3 which becomes the tightening part, and if more twisting force than necessary is applied, the metal wire 1 will break at the loop 2 part. It may also be cut. Either by forming a notch in this manner or by making the material weaker, a cut portion is provided in the loop 2 that will become the twist portion.

Figures 2A and 2B show other embodiments of the present invention; the ones shown in Figure 1A and 2B are right-handed, but this embodiment is left-handed; The configuration is the same as that of the previous embodiment.

Figures 4A, 4B and 4C show how a hose A is connected to a metal fitting B using a hose connection band C according to an embodiment of the present invention.

As shown in FIG. 4A, the hose A, in which the loop 3 which becomes the tightening part of the hose connection band C has been fitted in advance, is fitted into the metal fitting B, and a suitable rod D is inserted into the loop 2 which becomes the twisting part of the band C. Next, loop 2 is twisted by rod D as shown in FIG. 4B. This causes loop 3
is tightened and hose A is connected to fitting B. If more twisting force than necessary is applied, the metal wire 1 will be cut at the notch 8 formed in the loop 2. (4th
Figure C) As explained above, the hose connection band of the present invention does not require any special tools unlike the conventional ones, and can be easily twisted by simply inserting an appropriate rod into the twisted part of the hose connection band. The hose can be connected to the metal fittings, and the twisted part of the hose connection band can be cut by applying more twisting force than necessary, so the protrusion protruding to the outside is small and the protrusion does not get in the way. The present invention has a good appearance after connecting the hose, and can be manufactured at a low cost because it can be manufactured by simply bending a metal wire into a figure 8 shape.
