Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hose joint for connecting a foldable and windable drainage hose.

[Prior art]

As a conventional foldable and rollable hose,
For example, there is a fire hose. The extinguisher hose joint is made of metal and is fixed to the end of the extinguisher hose.

[The problem that the idea attempts to solve]

By the way, a collapsible and rollable drainage hose used for draining inland water has a diameter of, for example, 500 mm, which is larger than a fire extinguisher hose. If the metal annular hose joint is fixed to such a foldable and windable hose with a diameter of 500 mm, there is a problem that when the hose is wound, the hose joint becomes a hindrance and does not fit properly. For this reason, there is also the problem that it becomes difficult to bind the outer periphery of the wound hose. Further, there was a problem in that it was impossible to wind up one hose and then another hose if the hose had a metal joint.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a hose joint that solves the above-mentioned problems by making the joint that connects the hoses detachable.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention includes a flange formed into a flange shape by enlarging the end diameter of each collapsible hose that connects to each other, and a flange that is sandwiched between the flanges of the hoses. An annular member whose outer periphery is in contact with the inner diameter side, whose outer periphery is chevron-shaped in cross section, and whose diameter is approximately equal to the diameter of the hose; a cylindrical portion that is in contact with the outer periphery of the hose; and a hollow cut piece that is opposed to the outer periphery of the annular member at a distance from the outer periphery of the hose. A pair of annular hose end holding members each having a conical hose holding part and an annular plate-shaped fastening seat perpendicular to the longitudinal direction of the hose; The fastening member is fitted onto the connected hose so that the parts thereof face each other, and draws the fastening seat parts together to press the root side of the flange of the hose against the outer periphery of the annular member using the hose end pressing member.

[Effect]

By having the hose joint configured as described above, in order to connect the hoses, insert the cylindrical part of the hose end presser member into each hose, cover the outer periphery of the annular member from both ends so that the ends of the hoses match each other, and then press the ends of the hoses together. Bring the holding member into contact with the flange, pull the fastening seats of the hose end holding members together with the fastening member,
Each hose holding part presses the base of the hose flange against the outer periphery of the annular member, making it extremely easy to assemble a watertight hose joint, as well as removing the fastening member and pulling the hose apart. It can be disassembled by simply removing the annular member and pulling out the hose end holding member from the hose, so unlike the conventional structure where the metal annular hose joint is fixed, the hose joint does not get in the way when the hose is wound up. This does not occur, and it becomes easy to tie the outer periphery of the wound hose. Moreover, in addition to winding up a hose, it is also possible to wind up another hose.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a longitudinal cross-sectional view of the hose showing the structure of the hose joint according to the present invention. The hose joint includes flanges 2a and 2b formed at the ends of hoses 1a and 1b that are connected to each other, and flanges 2a and 2b.
and 2b, a pair of hose end holding members 9a and 9b, and a bolt nut 11 as a fastening member that draws and fastens the pair of hose end holding members 9a and 9b together. .

The hoses 1a and 1b are collapsible hoses such as soft PVC hoses containing synthetic fibers, and the ends thereof have flanges with a diameter larger than the diameter of the hoses when the hoses 1a and 1b become cylindrical due to the water pressure during water flow. 2
It is processed into a and 2b. This flange 2a,
2b, by making cuts in the longitudinal direction of the hoses 1a, 1b and enlarging them into a conical shape, flanges 2a, 2b with cuts 3a, 3b on the outer periphery can be formed as shown in FIG. . Further, the flanges 2a and 2b may be formed into conical shapes by enlarging the diameters of the ends of the hoses 1a and 1b without providing cuts in the longitudinal direction of the hoses as described above.

The annular member 5 is an annular member held between the flange 2a of the hose 1a and the flange 2b of the hose 1b. It is a chevron-shaped member having a diameter approximately equal to the outer diameter of 1a and 1b, and a cross section formed by outer circumferential surfaces 4a and 4b.

The hose end holding members 9a and 9b are connected to the cylindrical portion 6 and the hose 1 that are in contact with the outer peripheries of the hoses 1a and 1b, respectively.
Hose 1 and a hollow truncated cone-shaped hose holding part 7 which is arranged opposite to the outer periphery 4a, 4b of the annular member 5 with the fabric thickness on the base side of the flanges 2a, 2b of a, 1b
It is an annular member having an annular plate-shaped fastening seat part 8 that is perpendicular to the longitudinal direction of parts a and 1b.

Further, the bolt nut 11 is a fastening member that draws together the fastening seats 8 of the hose end holding members 9a, 9b and presses the root sides of the flanges 2a, 2b of the hoses 1a, 1b with the hose end holding members 9a, 9b. be.

Further, the bolt holes 12a of the flanges 2a, 2b,
12b and a hose end holding member 9 (not shown)
Bolt nuts 11 are inserted into the fastening seats 8 of a and 9b.

The annular member 5 is made of a hard material such as steel, synthetic resin, etc., and the hose end holding members 9a and 9b are
is made of sheet metal.

To explain the assembly and disassembly of the hose joint with the above structure, in order to connect the hoses 1a and 1b, insert the cylindrical parts 6 of the hose end pressers 9a and 9b into the hoses 1a and 1b, respectively, and press the ends of the hoses 1a and 1b. Keep it in a remote location. Next, the ends of the hoses 1a, 1b are placed over the outer peripheries 4a, 4b from both ends of the annular member 5 so as to match each other, and the hose end press members 9a, 9b are attached to the flanges 2a, 4b of the hoses 1a, 1b.
2b and abut against the flanges 2a and 2b. Here, bolt holes 12a, 12b of flanges 2a, 2b and hose end holding members 9a, 9
When the fastening seats 8 of the hose end holding members 9a, 9b are drawn together by the bolt nut 11 through which the hose end holding members 9a, 9b are drawn together, the hose end holding members 9a, 9b approach each other, and the respective hose holding parts 7 are attached to the hoses 1a, 9b.
Since the bases of the flanges 2a, 2b of 1b are pressed against the outer peripheries 4a, 4b of the annular member 5, watertightness is maintained.
To disassemble the hose joint, remove the bolt nut 11 and pull the hoses 1a, 1b apart, the annular member 5 will come off, and the hose end holding member 9 will separate from the hoses 1a, 1b.
This is done by pulling out a and 9b.

FIG. 3 is a vertical sectional view in the longitudinal direction of the hose showing the structure of another hose joint according to the present invention. In the figure, parts given the same reference numerals as in FIG. 1 indicate the same or equivalent parts. As shown in the figure, on both sides of the annular member 5 there are introducing portions 13 having a tapered outer diameter and a cylindrical inner diameter.
is provided. The large diameter portion of this taper is formed to be equal to or slightly smaller than the inner diameter of the hoses 1a, 1b. According to this embodiment, since the introduction portions 13 having tapered outer diameters are provided on both sides of the annular member 5, when the ends of the folded hoses 1a, 1b are made into cylindrical shapes, the introduction portions 13 are provided with the introduction portions 13 having tapered outer diameters. This makes it easier to insert the end.
