Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a pipe joint.

[Problems that conventional technology and ideas try to solve]

Conventionally, male and female elbow pipe fittings with a threaded hole and a male threaded section at right angles have a long distance from the axis of the male threaded section to the end surface of the threaded hole, and the male threaded section cannot be screwed into the threaded hole of another member. When moving them forward and backward, the turning radius becomes large, making it difficult to arrange a plurality of them in parallel at a small arrangement pitch.

Therefore, the object of the present invention is to make it possible to compactly mount a large number of male and female elbows in a small pitch, and to enable easy rotation even in a narrow space.

[Means to solve the problem]

In order to achieve the above-mentioned object, the pipe joint according to the present invention includes a body having a male threaded portion, which has a hole opening at its distal end surface, and which is integrally connected to the proximal end of the body. A male and female elbow pipe joint having a head formed with a threaded hole opening on the front surface thereof; a first connecting path being formed deep in the threaded hole in the head; A second connecting path is formed in the portion that bends or curves sequentially toward the first connecting path toward the rear, so as to connect the screw hole and the hole portion in communication with each other, and to connect the screw hole to the left and right sides and rearward of the head. A locking part having a square external cross-sectional shape, which forms a protruding surface, has the protruding surfaces in three directions, and the front surface of the head, and whose center point is located on the axis of the male threaded part. was formed.

[Effect]

If the work tool is locked in the work tool locking part and the head is rotated around the center point of the locking part, the male threaded part will rotate around its axis. It can be screwed in and out of screw holes in piping, etc. Moreover, there are no protrusions from the head,
The radius of rotation during the screw advance and retreat is extremely small.
Further, the screw hole and the hole portion are connected in communication with the first connecting path in the deep part of the screw hole and the second connecting path that is sequentially bent or curved backward toward the first connecting path. , the depth dimension of the screw hole can be made sufficiently large.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the drawings shown in the examples.

1 to 5, reference numeral 1 denotes a male and female elbow pipe joint, and a body portion 15 having a male threaded portion 3.
and a head 16 integrally connected to the base end of the body 15.
As shown in FIG. 6 and FIG.
8 is provided, and the head 16 is provided with a screw hole 2 on its front surface 5. The axial center 12 of the screw hole 2 and the axial center 7 of the male threaded portion 3 are made perpendicular to each other.

Reference numeral 4 denotes a work tool locking part in which a work tool 10 (see FIG. 9) such as a spanner, monkey, box, etc. can be locked, and the head 16 has protruding surfaces with a predetermined width M on the left and right sides and rear. 19, 20, 6, and the protruding surfaces 19, 20, 6 in three directions and the front surface 5 of the head 16.
It is formed by the following. That is, this locking portion 4
The external cross-sectional shape is a square, and its center point 8
is arranged on the axis 7 of the male threaded portion 3. Note that the predetermined width M is set to a size sufficient to withstand the rotational torque of the power tool 10.

As shown in FIGS. 6, 7, and 8, a first connecting path 21 is formed in the deep part of the screw hole 2, and a first connecting path 21 is formed in the deep part of the hole 18. A second connecting path 22 is formed that sequentially bends or curves rearward toward the passage 21, and the inner hole 9 consisting of the first connecting path 21 and the second connecting path 22 connects the screw hole 2 and the hole 1.
8 are connected in communication.

Next, FIG. 9 shows a state in which a plurality of pipe joints 1 are attached to the threaded holes 13 of the pipe 11. That is,
The work tool 10 is locked to the locking part 4, and the head 16 is
When rotated around the center point 8 of the locking part 4, the male threaded part 3 rotates around its axis 7, and the threaded hole 1
3 can be screwed on.

Therefore, when a box wrench is used as the working tool 10 as shown in the figure, it is only necessary that the working tool 10 is locked in the locking part 4 and that the tool 10 is rotatable around its axis. This pipe joint 1 can be attached to a plurality of screw holes 13 having a small arrangement pitch P.

[Effect of idea]

Since the present invention is constructed as described above, it produces the following effects.

Work tools such as spanners, monkey bars, boxes, etc. can be easily locked in the work tool locking part 4,
Moreover, if this pipe joint is rotated around the center point 8 of the locking part 4, the male threaded part 3 will rotate around its axis 7, and the threaded hole 13 of the pipe 11 etc. will rotate.
Screwing forward and backward operations can be easily performed, and attachment and detachment operations to and from the pipe 11 can be easily performed.

Further, the head 16 has no protrusion in the outer diameter direction,
The rotation radius can be made extremely small, and it can be attached to and detached from a plurality of screw holes 13 arranged in parallel in a small pitch, and a plurality of pieces can be easily arranged in close proximity even in a narrow space.

Furthermore, the depth of the screw hole 2 can be made sufficiently large, and the pipe threaded into the screw hole 2 can be reliably connected to the pipe joint 1.
