[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swingable pipe joint, and more particularly, to a swingable pipe joint capable of favorably performing piping such as water supply and sewerage.

[0002]

[Prior Art]

 In general, when the pipes are connected in a bent state, a plurality of deformed joints such as elbows and nipples are used as a pair of pipes to be connected for piping.

[0003]

[Problems to be solved by the device]

 However, since the conventional piping means uses a large number of deformed joints, the number of parts is unnecessarily increased, and a series of piping work becomes extremely complicated, resulting in a serious lack of workability. Had a problem.

Further, since such piping means has no flexibility, it is difficult to perform piping work or change work after piping when there is a deviation in the axial center of the pipe body to be connected. In both cases, when an external force is applied to the pipe body or the piping portion, each of these members is damaged and the circulating fluid leaks.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and by providing the pipe joint with flexibility and simplifying the piping configuration, a series of pipe distribution work can be performed. The task is to provide a large amount of flight.

[0006]

[Means for Solving the Problems]

 That is, in order to achieve the above object, the present invention provides a bend 1 having a spherical bulging portion 2 formed at least at one end thereof, and a spherical concave shape that is fitted into the spherical bulging portion 2 of the bend 1 so as to be spherically slidable. It is a swingable pipe joint including a joint body 3 in which a portion 4 is formed.

[0007]

[Action]

 When a pipe joint characterized by the above-mentioned structure is connected by pipes to connect a pair of pipes to be connected, the pipe joint is provided with a bend 1, so that the pipe to be connected is bent. It will be piped in the state.

Further, since the spherical bulging portion 2 of the bend 1 is spherically slidably fitted in the spherical concave portion 4 of the joint body 3, both of them oscillate with each other. Can be oscillated appropriately for piping, and the connection angle of the pipe to be connected can be increased, and if an external force is applied to the pipe or pipe joint to be connected after piping, , The both swing and the external force is absorbed.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a bend in which spherical bulging portions 2 are bulged at both ends, and the bending angle α thereof is set to 30 °.

Reference numeral 3 denotes a joint main body in which a spherical concave portion 4 which is fitted to the spherical bulging portion 2 of the bend 1 in a spherically slidable manner is formed on the inner peripheral surface, and the other end of one joint main body 3 has A flange 5 having a flange shape is provided.

Reference numeral 7 indicates a packing for sealing. Reference numeral 8 denotes a space portion formed between the outer peripheral surface of the spherical bulging portion 2 of the bend 1 and the inner peripheral surface of the end portion of the joint body 3, and the space portion 8 is surrounded by a plurality of arc-shaped retaining members 9 as shown in FIG. It is attached via a detachable insert.

Reference numeral 10 is a ring body fitted in an annular recess 11 formed on the inner peripheral surface of the end of the joint body 3 in order to prevent the retaining body 9 from coming off, and has a partial cutout 12 as shown in FIG. Become. Reference numeral 13 is an arcuate insert inserted in the notch 12 of the ring body 10, and a screw hole 14 is formed at the approximate center of the outer peripheral surface thereof. Reference numeral 15 is a screw hole formed in the outer peripheral surface of the end of the joint body 3 in the radial direction. Reference numeral 16 is a screw screwed into the screw hole 14 of the insert body 13 through the screw hole 15 of the joint body 3, whereby the rotation of the ring body 10 is blocked.

The present embodiment is configured as described above, and the swingable pipe joint 17 is used by being buried in the ground for use as a joint for a water pipe, for example. The use example will be described below. ..

First, as shown in FIG. 1, the connected pipes 18, 18 are connected to the other end of the joint body 3, respectively. In this state, the bend 1 and the joint body 3 do not swing, and the two pipes 18 to be connected are connected at a connection angle of 30 °. That is, since both connected pipes 18, 18 can be connected at a connection angle of 30 ° only by such a swingable pipe joint 17, the piping configuration between both connected pipes 18, 18 can be simplified. Therefore, the piping work can be performed easily and quickly.

Further, since the bend 1 is configured to be swingable with respect to the joint body 3, it has the flexibility of continuously changing the connection angle of the pipes 18, 18 to be connected.

That is, if the pipes 18 and 18 are rocked as shown in FIG. 4, the pipes 18, 18 can be connected in a substantially straight line. On the other hand, if the pipes 18 are rocked as shown in FIG. The bodies 18 and 18 can be connected to each other, so that even if there are obstacles such as gas pipes and sewer pipes installed underground, such obstacles can be avoided satisfactorily.

Further, when the axes of the pipes 18 and 18 to be connected are displaced from each other by the distance H as shown in FIG. 6, or the connection angle of the pipes 18 and 18 to be connected is changed later. Even in this case, it is possible to flexibly cope with the situation by appropriately swinging the bend 1 and the joint body 3.

Further, since the bend 1 and the joint body 3 are provided with a plurality of arc-shaped retaining members 9 in the space 8 to prevent the bend 1 from retaining, the assembling and disassembling work is simplified. There is also an advantage that

Although the bending angle α of the bend 1 is set to 30 ° in the above embodiment, the present invention is not limited to this, and the bending angle α can be arbitrarily changed. Is. For example, a case where the bending angle α is set to 60 ° is shown in FIG. 7. By appropriately changing the bending angle α of the bend 1 itself in this way, for example, misalignment is performed and a coupled object having a considerable axial distance is connected. The pipes 18, 18 can be easily connected.

Further, in this embodiment, the retaining body 9 and the ring body 10 and the like are used to maintain the connected state of the bend 1 and the joint body 3, but it is not always necessary to constitute in this way, The specific configuration of the maintenance means does not matter.

Further, although the spherical bulging portions 2 are formed at both ends of the bend 1 in the above embodiment, the spherical bulging portions 2 are formed only at one end and the joint body 3 is swingably connected. Of course, it is possible to make changes according to the usage mode, intended use, and the like.

Further, the design of each part such as the shape of the joint body 3 can be arbitrarily changed within the scope intended by the present invention.

[0024]

[Effect of the device]

 As described above, since the present invention is provided with the bend, it is possible to connect two pipes to be connected at a constant connection angle with one swingable pipe joint, so that a large number of valves can be connected. Compared with the conventional one that used a nipple or the like, the piping configuration can be simplified, and the special effect that the piping construction work can be performed extremely easily and quickly has been obtained.

Further, since the spherical bulging portion of the bend is spherically slidably fitted in the spherical concave portion of the joint body, the two connected pipe bodies can be connected by appropriately swinging them. It is possible to connect pipes continuously and at wide angles, and to easily connect connected pipes that are misaligned, and when external force is applied to the joint body due to ground subsidence, etc. As a result, the external force that is oscillated and the external force applied is absorbed well, and as a result, it is possible to avoid the inconvenience of leaking the circulating fluid.

Further, since the swingable pipe joint according to the present invention has a very simple structure, there is a practical advantage that the swingable pipe joint can be manufactured easily and inexpensively.
