[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe fitting used for a fluid piping system.

[0002]

2. Description of the Related Art In piping such as vinyl chloride, conventionally used pipe fittings are, as shown in FIGS. 4 and 5, one of pipes 21 and 22 connected to each other, for example. When a large-diameter fitting receiving portion 21A is formed at the end of the tubular body 21 and the other end of the tubular body, that is, the end 22A of the tubular body 22 is fitted in a liquid-tight manner through the rubber ring 23, Used. The connecting device includes two pairs of split ring bodies 24A, 24B and 25A, 25B divided into two in the radial direction;
4A, 25A and 24B, connecting rods 26A, 26B respectively connecting the 25B, and in a state where both pipe bodies 21, 22 are joined as described above, one split ring body 24A, 24B is connected. The fitting receiving portion 2 in the longitudinal direction
The split ring 24 is positioned so as to be locked with respect to 1A.
A, 24B and 25A, 25B are respectively connected to the tube 21,
The pair of split rings are joined and fastened to the outside of the tubes 21 and 22 by bolts 27 and nuts 28 which are fitted on the tube 22 and cross in the longitudinal direction. In this case, the connecting rods 26A, 26B
Are locking portions 3 provided with locking portions 29, 30 formed on both ends thereof on each split ring body 24A, 24B and 25A, 25B.
When the bolts 27 and nuts 28 are fastened in this state, the pair of split ring members are connected to each other.

[0003]

[Problem to be solved by the invention] In such a configuration,
By using the above-mentioned connecting tool, a thrust load is applied to a place where the rubber ring 23 is joined, and it is possible to prevent the fitting portions of the pipes 21 and 22 from coming off. However, the fittings are separate split rings 24A, 24B and 25A,
5B must be tightened with bolts 27 and nuts 28. At this time, the connecting rods 26A and 26B must be incorporated at the same time, so that the work at the time of setting is troublesome, and the number of parts is also small. Are four, connecting rod 2
6A and 26B are two, and bolt 27 and nut 28 are four each, which is very large, and parts management is troublesome.

[0004]

[Purpose of the Invention] The present invention has been made based on the above circumstances, and aims to provide a pipe connector which is easy to install at the time of setting, and has a reduced number of parts to facilitate parts management. Is what you do.

[0005]

Therefore, in the present invention,
As also shown in the illustrated embodiment, the tubes (1,
2) forming a large-diameter fitting receiving portion (1A) at one end;
When the other ends of the pipes (1, 2) are inserted in a liquid-tight manner and the two pipes (1, 2) are joined, when the two split ring bodies (4A, 4B, 5A, 5B) to each tube (1,
2), and each pair of split rings (4A, 4B, 5A, 5A,
B) is joined outside the tubular body (1, 2), and at least one of the left and right split ring bodies (4A, 5A) is connected to the connecting piece (6).
In the pipe connecting device connected via A), one pair of the split ring bodies (4A, 4B) is fastened so as to sandwich the pipe (2) by a fastener, and the other is used. The pair of split ring bodies (5A, 5B) are fitted to the pipe body (1) with a fitting diameter such that the split ring bodies (5A, 5B) are locked with respect to the fitting socket part (1A) in the longitudinal direction of the pipe body (1). The split ring (5A) is fitted and the split ring (5B) is inserted from the fitting receiving port side.
And radial engagement portions (51A, 51B) that abut against each other in the longitudinal direction of the tube (1, 2).

[0006]

Therefore, when the connecting tool is set, the other split ring (5)
A, 5B) are slid in the longitudinal direction, and are engaged with the fitting receiving portions (1A) in a state where the radial engagement portions (51A, 51B) are engaged with each other. If the split ring members (4A, 4B) are fastened with fasteners such as bolts and nuts, the attachment of the connector to the pipes (1, 2) can be completed easily. Can be significantly simplified. And the number of parts is at least
Since the split ring (4A, 5A) and the connecting rod (6A) are respectively integrated, the number of parts is greatly reduced, and parts management becomes easy.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to FIGS. The connection tool in the present invention forms a large-diameter fitting socket 1A at one end of the pipes 1 and 2 connected to each other, for example, at the end of the pipe 1, similarly to the conventional case. It is used when the other end of the tubular body, that is, the insertion opening of the end 2A of the tubular body 2 is fitted in a liquid-tight manner via the rubber ring 3. In the first embodiment shown in FIGS. 1 and 2, the connecting tool is opposed to two pairs of split ring members 4A, 4B and 5A, 5B divided in the radial direction and front and rear of both split ring members. It has left and right two connecting pieces 6A and 6A for integrally connecting one half-ring body 4A and 5A at right and left outer ends thereof, and the other half-ring bodies 4B and 5B are separated from each other. I have. Further, the second embodiment shown in FIG. 3 further includes one connecting piece 6B for integrally connecting the other two half-ring bodies 4B and 5B at a curved intermediate portion thereof. In each of the embodiments, the split ring members 4A, 4B
Is provided with bolt through holes 42A and 42B in the flange portions 41A and 41B on both sides, and the bolts 7 are passed through the flange portions 41A and 41B so that both split ring bodies 4A and 4B It can be fastened. The split rings 5A and 5B have a fitting diameter D fitted to the pipe.
And the split ring 5B
Are inserted from the fitting receiving portion side toward the split ring body 5A, and are engaged with each other in the longitudinal direction of the tubular body.
1A and 51B.

In the above embodiment, the engagement portion 51A
Has a slot inside the thick protruding piece that opens toward the radially inner side of the split ring 5A and toward the fitting receiving port, and the engaging portion 51B is It has the shape of a thin protruding piece inserted into the slot.

In such a configuration, the split rings 5A, 5A
B is positioned at the base end of the fitting receiving portion 1A of the tubular body 1 at a position where it is engaged in the longitudinal direction of the tubular body. 2 (see FIG. 2), and in this state, the connecting piece 6
A (or in the second embodiment, the connecting piece 6A
And 6B) the other split ring 4A, 4B
Is determined. Then, bolt 7, nut 8
The split rings 4A, 4B from the cross direction
Is fixed to the tube 2. When the connecting member is set in this manner, the split ring members 4A and 4B are engaged with the fitting receiving portion 1A in the longitudinal direction of the tubular body even if the tubular body 2 tries to come out of the tubular body 1. Together, it blocks that movement. This is because the radial engagement portions 51A and 51B are engaged with each other in a direction crossing the longitudinal direction of the tubular body, so that the split ring members 5A and 5B cannot be separated from each other in the radial direction.

In the above embodiment, bolts and nuts are used as fasteners, but it is a matter of course that other connecting means may be used.

[0011]

As described in detail above, the present invention has a structure in which one pair of split ring members is fastened so as to sandwich the tube by a fastener, and the other pair of split ring members is fitted. The pipe is fitted to the pipe with a fitting diameter such that the pipe is locked in the longitudinal direction of the pipe with respect to the socket, and one of the split ring bodies of the latter pair is connected to the fitting port from the fitting port side. It has a radial engagement portion that is fitted toward the other split ring body of the pair and abuts each other in the longitudinal direction of the tube body. In the direction in which the radial engagement portions are engaged with each other, and in a state where the engagement portions are engaged with the fitting receiving portions,
In this state, if the former pair of split ring bodies is fastened with fasteners such as bolts and nuts, the attachment of the above-mentioned connector to the pipe is completed easily, so that the workability is remarkably compared to the conventional one. Can be simplified. Moreover, the number of parts is at least greatly reduced since the split ring and the connecting rod are integrated with each other, so that parts management becomes easy.
