A hexahedron block is provided, and at least three pipe lines are formed to penetrate through the block in different directions, and at least one other pipe line in which each pipe line has a different penetrating direction at an intermediate portion thereof. And the threaded portion for connection is formed at the opening of each pipeline.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe joint.

[0002]

[Prior art]

 FIG. 4 shows an example of a conventional piping configuration. Reference numeral 1 is a pipe joint used for branching the pipe 2. In this type of pipe joint 1, the pipe line is formed by branching into a cross shape or a Y shape. For example, in the cutting oil pipe 2 disposed in a machine tool or the like, the joint 1 is connected to a place where the cutting oil needs to be supplied, and the cutting oil is attached via a nozzle member attached to the opening. Was squirting.

For this reason, in the case of the pipe 2 which requires a large number of branch points, as shown in the figure, a plurality of the cross-shaped or Y-shaped joints 1 are combined to form a pipe structure. It is the current situation.

[0004]

[Problems to be solved by the device]

 However, in the case of conventional piping joints, even if they are cruciform, they can branch only in the other three directions at the maximum, so there is no adequate margin around the piping when branching in multiple directions. It is difficult to diversify the pipe by connecting cross-shaped or Y-shaped joints with each other, and even if it is possible to connect the joints as described above, if there are many branching points, the appearance will be poor. There was a problem that the unity was lost and the product value decreased.

The present invention has been made under the above circumstances, and an object of the present invention is to provide a pipe joint that can be branched in various ways without damaging the outer appearance when branching the pipe. Especially.

[0006]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a block composed of a hexahedron, and forms at least three conduits penetrating in different directions in the block. , And a pipe joint in which each pipe is communicated with at least one other pipe having a different penetrating direction at the middle portion thereof, and a screw portion for connection is formed in the opening of each pipe. To do.

[0007]

[Action]

 According to the present invention having the above-described structure, the pipe can be branched into six or more directions by connecting the pipe joint according to the present invention into the pipe. In other words, it is possible to branch in the desired direction by connecting the opening of the required pipeline to the pipe and connecting the unnecessary pipeline to the opening by screwing a stopper screw into the blind. Since the piping is branched without connecting many joints of this kind, space can be saved in the piping and the appearance is not damaged.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In this embodiment, the same reference numerals are used for the portions having the same structures as those of the conventional structure shown in FIG. 4, and the description thereof will be omitted.

1 and 2 show an embodiment of the present invention. Reference numeral 1 is a hexahedral block made of steel or the like, and three pipelines 11, 12, and 13 are formed in the block 1, and the respective pipelines communicate with each other at an intermediate portion, and The threaded portion 1a for connection is formed in the opening 10 and is configured.

That is, the pipe lines 11, 12, and 13 are provided so as to penetrate between the respective facing surfaces of the block 1 in the vertical direction x, the horizontal direction y, and the height direction z, and the respective pipe lines are formed inside the block 1. The pipes are made to be orthogonal to each other so that the respective pipes communicate with each other. In the figure, the pipe lines 11, 12 and 13 communicate with each other at right angles to each other, but for example, other pipe lines 12 and 13 are connected to the pipe line 11 in the middle of the pipe line 11. It is also possible to provide the parts in communication at different positions.

The connecting screw portion 1a formed in the opening 10 of each of the pipe lines 11, 12 and 13 is provided so as to be screwed with the end portion on the pipe side, and the opening portion not connected to the pipe. A nozzle member or the like can be attached to the nozzle 10, and a stopper screw (not shown) is screwed into the opening of the nozzle when the corresponding conduit is unnecessary.

Thus, the direction of the pipe can be branched at the location where the block 1 is arranged in the pipe, and for example, in the case of cutting oil pipe or the like, the jetting destination is desired via a nozzle member or the like. It is possible to set the direction, and the ejection points are provided by the number of other openings.

Further, the respective pipelines may be communicated with each other at an appropriate angle instead of being orthogonal to each other, and the intersecting angle is determined by the arrangement direction of the respective pipelines. When the pipe runs obliquely between the facing surfaces of the block in this way, the threaded portion 1a for connection is formed in the opening of the pipe after appropriate means such as spot facing is applied to the pipe. It is necessary to install so that leakage does not occur when connecting with a stopper screw or nozzle member.

FIG. 3 shows another embodiment of the present invention in which a block 1 made of a rectangular parallelepiped is provided and a pipe line is provided in the block 1.

For example, with respect to the pipeline 11 penetrating in the horizontal direction y of the block 1, pipelines 12 a and 12 b in the vertical direction x communicating with the pipeline 11 are provided at appropriate intervals, and The pipes 13a and 13b in the height direction z communicating with 11 are provided at appropriate intervals, and the connecting screw portion 1a formed in the opening of each pipe is formed. The same connection as in the above-mentioned embodiment is made, and a stopper screw (not shown) is screwed to an unnecessary pipe (opening) to make the pipe a blind pipe.

[0016]

[Effect of device]

 As described above, according to the present invention, a block composed of a hexahedron is provided, and at least three pipe lines are formed so as to penetrate through the block in different directions. At least one other pipe with a different penetration direction is made to communicate with each other, and a threaded portion for connection is formed at the opening of each pipe, so that the pipe can be connected in the desired direction with one joint. It is possible to branch, and since piping is branched without connecting multiple joints of this kind, it is possible to save space and not to damage the appearance of the piping itself. Is played.
