Description

[Detailed Description of the Invention] This invention relates to a hose fitting, for example, a fluid branching hose fitting for branching fluid in a brake hose.

A vehicle's brake hose is an extremely important safety component. Therefore, in vehicle assembly work, there is a need for brake hose piping to be able to be connected reliably and quickly in a narrow space.

FIG. 1 shows a conventional piping connection portion of a brake hose to a vehicle body such as a motorcycle (hereinafter referred to as the attachment portion main body 1).

In other words, in this case, the end of the hose 2 is held between the nipple part 9 and the socket part 7 on the surface of the fluid hole 17 of the attachment part main body 1 that brakes the disc on one side of the wheel, and the extension part of the nipple part 9 on the outside of the bottom part. A connector 1 having a bolt hole 32 in a cylindrical portion 11 in a direction perpendicular to the axial direction of the nipple portion 9.
The connector 13 of the hose connection fitting 5 with 3 is placed through the packing 15, and the end of the hose 3, which is similar to the hose connection fitting 5, is sandwiched between the nipple part 10 and the socket part 8 on the upper surface of the connector 13. In addition, the connector 14 of the hose connection fitting 6 with the connector 14 having the bolt hole 33 in which the connector 14 is placed is placed in the cylindrical portion 12 through the packing 15, and the tightening bolt 4 is inserted through the packing 15 and the bolt hole. 33, 32 and is screwed into the mounting body 1 side, and if pressure fluid is supplied in the direction of the arrow at the end of the hose 2, it will flow through the through hole 16 of the bolt 4. Some of the branched fluid flows into the fluid hole 17 of the attachment body 1.
Another part of the branched fluid is supplied to a hose 3 to apply a brake to a disk on the other side of the wheel, although not shown. However, in this case, two identical hose connection fittings 5 and 6 are used for the mounting body 1, and each connector 1
3 and 14, the connecting portion becomes large and takes up space, and the weight is also large, which is uneconomical. Moreover, since the number of gaskets 15 used increases, it becomes difficult to install them, which has the disadvantage of adversely affecting workability.

The purpose of this invention is to eliminate the drawbacks of the prior art described above and to provide a fluid branching hose fitting that is small and lightweight, and allows reliable and quick piping of the brake hose to the vehicle body.

The gist of this invention is that in a hose fitting which has a hose clamping part having a socket part and a nipple part at one end and a cylindrical connector at the other end, the one connector has at least two The hose fitting is characterized in that the two hose holding parts are attached at arbitrary angles.

Hereinafter, one embodiment of this invention will be described with reference to the drawings. In FIG.
and at least two hose clamping parts 34, 3 which clamp the ends of the hoses 2, 3 with the nipple parts 21, 22.
The protruding cylindrical portions protruding from the bottoms 29, 30 of the nipples 21, 22 outwardly extend from the bottoms 29, 30 of the nipples 21, 22. The two clamping portions 34, 35 and the connector 23 are fitted into respective fitting holes provided on opposite sides of the flat connector 23, and are integrated with each other by, for example, brazing. In this case, it goes without saying that the nipple hole and the through hole 31 of the connector 23 communicate with each other when the hose holding parts 34 and 35 are fitted. 24 is a ring-shaped packing provided to prevent fluid leakage.

When the hose fitting 25 having such a configuration is to be attached to the mounting body 1 of a brake mechanism such as a motorcycle, for example, for use as a pressure fluid branch, the hose fitting 25 is first attached as shown in FIG.
After inserting the ends of the hoses 2 and 3 between the socket part 19 and the nipple part 21 and between the socket part 20 and the nipple part 22, which constitute the two hose holding parts 34 and 35, the socket parts 19 and 20 are inserted into the nipple part 2.
The hoses 2 and 3 and the hose fitting 25 are integrated by compressing and reducing their diameters on the 1 and 22 sides, and the bolt hole 31 of the connector 23 of the hose fitting 25 is aligned with the flow hole 27 of the attachment body 1, and the first If the bolt 18, which is shorter than the bolt 4 shown in the figure and has a through hole 26, is screwed into the attachment body 1 side through the hole 31 and the packing 24, the hose fitting 25 can be attached to the attachment body 1 ( connection) is completed. In this case, the sealing surface by the packing 24 is reduced by one area compared to the conventional case, which is effective in preventing fluid leakage.

In addition, by connecting in this way, the pressure fluid sent from the end of the hose 2 passes through the bolt hole 31 of the connector 23 portion of the hose fitting 25 and the through hole 26 of the bolt 18 to the attachment body. This means that the pressure fluid is divided into the 1 side and the hose 3 side, respectively.

In this example, the hose clamping parts 34 and 35 are positioned in a straight line through the connector 23, but the hose clamping parts 34 and 35 can be positioned at various angles by changing the brazing position to the connector, for example, as shown in FIG. The hose clamping parts 37 and 3 are connected to each other with the connector 36 as the boundary.
It is also conceivable to use a right-angled hose fitting 39 that forms a right angle with 8, and it is also conceivable to provide the connector with three or more hose holding parts.

In addition, in this example, the hose holding parts 34 and 35 and the connector 23 material are used separately and are integrated by brazing or the like, but the connector and the hose holding part are made of one piece. There is no problem.

As mentioned above, according to the hose fitting of this invention,
Since it has a structure in which several hose holding parts are provided on the outer surface of one connector, it does not take up space at the connection part of the mounting part body as in the past, and it also reduces the amount of materials required, making installation work easier. In addition, the cost of processing the hose fittings is considerably lower, and its practical value is great.
