The annular buffer body 8 interposed between the Norange/ and 7' is made of a '-1 mm elastic body, has a substantially rectangular cross section, and has several annular reinforcing plates 11 on its side and inside. In addition to increasing the rigidity and durability of the rubber elastic body,
The force applied by the seven flange 7°7' is dispersed and received. A protrusion 12 is formed on the inner and outer circumferential surfaces of the buffer body 8, and the protrusion 12 is connected to the inner cylinder 6 and the outer cylinder 4.
The shock absorber 8 is allowed to freely slide while being in contact with the peripheral surface of the shock absorber 8. In addition, the protrusions 12 allow arbitrary positioning between the inner cylinder groove and the outer cylinder 4 of the sliding body 8, and
This is effective for securing deformation space.

The inner circumferential surface of J・B) is in contact with the outer circumferential surface of the connecting cylindrical bodies 2, 2' and the inner circumferential surface of the outer cylinder 4, respectively. It is flexible within each current space.

In the split bodies 8 and 9, the annular reinforcing plates 11 need only be provided at least on both sides, and the annular reinforcing plates 11 may be embedded in the rubber elastic body, or if they are embedded in the rubber elastic body, the enemy ship Optional.

The shape of the shock absorbers 8 and 9 depends on the conditions of use, and C is not limited to the embodiment, but may be round or rectangular in cross section, and may be made of only a 1 mm elastic body, and may not have the sharp protrusions 12. But that's fine.

In addition, the connecting cylindrical bodies 2, 2' are shown in Fig. 4 (a), (b) &J
It is also possible to use a small band-shaped body, a rod-shaped body, etc., fixed to the shaft 7' so as to form a cylindrical shape as a whole.

Further, the buffer body 9 is also divided into connecting planar bodies 2 and 2'.

The lanyard 7' moves horizontally and/or vertically in the drawing, allowing the parts A and A' to be connected to expand, contract, and swing.

Taking as an example the case of moving from side to side in the drawing as a midline operation, first one of the lunges 7 is moved from the reinforcing plate 11. By pushing the shock absorber 8 toward the external force 7 lange 7', the first impact force is alleviated, and both flanges 7 and 7' push the shock absorber 8 from both sides. When operating in the pushing direction H-1, the shock force is alleviated due to the 2-degree shape of the buffer body 8. Alternatively, if the flanges 7.7' move in the direction away from each other, the shock absorbers 9.
By squeezing -4-, &'JYM force is relaxed and the expansion/contraction displacement of connected pipes A and A' is accommodated by R'+°.

Your best friend for growth! +t, 1'z: Due to the rigidity of the thin body 8, the maximum contraction 1t1 is regulated by J1.

In this embodiment, the buffer 8 is also used!

Since the pipe is placed in the same position, the displacements such as expansion and contraction between the connected meridians and the pipes A and A' after the break are to be observed.

In addition, in the case of deflection displacement, the shock absorber 8 is applied to both the periphery or the inner periphery (Fig. The paddy body 9 is pinched and pressed by the inner circumferential edge or the outer circumferential edge of the buffer bodies 8 and 9, and the impact force is alleviated by the compressive deformation of the buffer bodies 8 and 9. +1-2, ri υ tangent F'X 'IRA+
"σ) The force acting due to the deflection displacement is dispersed at the inner and outer periphery of each of the 7 flange 7.7', and in the case of the embodiment, the force acting on the 7 lange 7.7' and the spinning [body 8, 9] By interposing the current reinforcing plate 11... between them, the flanges 7, 7' and the reinforcing plate 11 come into surface contact, so that the reinforcing plate 11... reduces the concentrated load on the shock absorbers 8, 9. will be further avoided.

This permissible deflection position depends on the rigidity of the buffer body 8.9 and the regulating body 5. 5', 6.6' will be regulated within a certain range.

FIG. 6 shows, as an embodiment of the second invention, a pipe coupling device 2o in which six pipe coupling units 1 in the first embodiment are arranged in series as a structural unit.

The configuration of the pipe fitting unit 1 as such a configuration is as follows:
Since this is the same as in the first embodiment, the same parts are given the same reference numerals and their explanations will be omitted. Then, the connection between the pipe joint units 1 or the connected pipes A and A' is performed by connecting the connecting cylindrical bodies 2° 2' to each other or to the connecting cylindrical bodies 2. 2μ and connected pipe A-.

A' are connected to each other, and the pipe joint device 20 of this embodiment and [-() are constructed.

According to this device 20, the maximum permissible amount of relative displacement between the connected pipes A and A' or its regulation can be set as the sum of the maximum permissible amounts of the individual constituent units, etc., and can be easily made uniform.

In other words, even if a large force is exerted due to the relative displacement 4 between the connected pipes A and A, sufficient durability can be obtained while allowing the large displacement R1f.

Of course, the number can be selected as appropriate, with the pipe joint unit 1 as a constituent unit.

For example, in the case of water pipes used to draw seabed water in temperature difference power generation, they are suspended directly from the sloped ground in the Wij and are carried over long distances without being supported along the way. Since the skeleton is directly influenced by the outside world due to current flow, it is advantageous to use this pipe coupling device l''I.

As is clear from the following description, the present invention provides a pair of annular 7 flanges at the inner end of the connecting cylindrical body, and inserts annular 7 flanges into the existing space on both sides of the flanges. Since the shock absorber is provided, relative displacement of the connected pipe is allowed by compressing deformation of the shock absorber by 4'P, and also due to the shock absorber and the regulating body protruding from the inner cylinder and the outer cylinder. Regulated.

Moreover, since the flange extends both in the inner and outer circumferential directions of the connecting tube, the contact surface between the seven flange and the buffer body can be widened, and the bending displacement of the connected pipe can be prevented.
The 1i'tl edge of a pair of 7 flanges is the same or the outer periphery edges pinch the buffer body interposed between the flanges, and the low periphery edges are interposed between the regulating body, +1. Since the shock absorber is compressed and the force acting due to the deflection displacement is dispersed and received, it is possible to reasonably control the force caused by the relative displacement.
