A connecting member (60) is connected to the first piping (21) in such a way as to be capable of relative rotation about a first axis and to the second piping (22) in such a way as to be capable of relative rotation about a second axis perpendicular to the first axis, so that the first piping (21) and the second piping (22) make relative spherical motions via the connecting pipe (50).

Description

<Field of the Invention> The present invention relates to a piping joint and a fire truck; the fire truck is a person who transports a fire-fighting fluid by using the pipe of the joint. -<Related technology description> As shown in FIG. 9, 'In order to form a bendable path from two pipes 丨 〇1 and 〇2, one end of each pipe 010, 102 is machined along a spherical shape. It is an existing conventional technique to connect the spherical members through the bifurcated sealing member 103 to perform spherical motions. Jiawei is one another, and the two-pressure performance is connected on the mountable consumer components, which hinders the cost of processing the fire truck &amp; 'Need to upgrade the precision pipe 1 0 1, 1 and make small Anti-mobile or ladder knotted hose. The clear purpose of this kind of hose is to increase the two pipes. The degree of accuracy is good, the relative diameter of the ladder is relatively high, and the water gun is used for fire fighting. It is to mention that it is difficult to process the center of each part along the spherical surface. It is difficult to increase the f-curve angle and the resistance of the joint.

Two rooms

5. Description of the invention (9) The opening of the connecting portion 22b at the lower end of the second pipe 22 is opposite to the opening at the upper end of the first piping unit 21 described above. A pair of second receiving portions 22k are integrally opened on the lower end surface of the connecting portion 2 2b. The two second receiving portions 22k are arranged in the circumferential direction of the second piping and are 180 degrees apart from each other. In addition, a plurality of peripheral grooves 22m are provided on the outer periphery of the body 22a of the second pipe 22. Between each of the peripheral grooves 22m and the inner periphery of the holding cylinder 23, an annular pressure oil flow path is formed. Each hydraulic oil flow path is connected to a hydraulic device such as a hydraulic regulator for ladder rocking via a hydraulic oil pipe connection port (not shown); those that are open on the outer periphery of the holding cylinder 23, 哕 掸; # The one mounted on the platform 4; as shown in the figure, the lower end and the upper end of the pressure regulator system 22a are opened I, and the vehicle body is inserted into the battery of the electrical component that is inserted into the through hole 22r.

The connecting tube 50 is paired with i and 2

Page 12 4nasil V. Description of the invention (10) &quot; &quot; '----- The axial direction of the tubes 21 and 22 is too large. ^ Figure 5 is shown by a ring-shaped member surrounding the connecting pipe 50: The member 1. 60 can be connected to the center of the first axis A relative to the rotation axis. That is, the connection member 60 is disposed between the pair of first receiving portions 21c, and is twisted into each of the i-th receiving portions 21c—a pair of torsion shafts η == is inserted into the connecting member 6 in a relative rotation. The relative axis of rotation in the through hole formed above is the first axis A. As shown in FIG. 4, the second pipe 22 is connected to the connecting member 60 so as to be rotatable about the center of the second axis B, and the second axis B is eight perpendicular to the second axis. That is, the connecting member 60 is disposed between the pair of second receiving portions 22k, and is twisted into one pair of the torsion shafts 62 of each of the second receiving portions 221, and is relatively rotatably inserted into the connecting member 60. In the formed through hole, the relative axis of rotation is the second axis B. The first axis A and the second axis B are perpendicular to the above-mentioned swing axis c of the vehicle body 2 on the stage 4. In addition, the first axis A, the second axis β, and the swing axis c intersect at- The parent point is the center r of the spherical motion of the platform 4 to the vehicle body 2. Dream this' The first pipe 21 and the second pipe 22 can perform a spherical motion through the connecting pipe 50, the center of the spherical motion R, and the center of the spherical motion of the phase of the stage 4 on the vehicle body 2 is concentric. The center of the connecting tube 50 passes through the spherical motion center β. In order to adjust the center r of the relative spherical motion of the first and second pipes 21 and 22 to be slightly adjusted to match the center of the relative spherical motion of the stage 4 to the vehicle body 2, the ideal one is to The installation position of the first piping 2 on the stage 4 of the ampere-position guard 23 on the vehicle body 2 side is made of, for example, a two-letter type in which a holder is installed.

P. 13 Wu Mingyu The through hole is made into a cover hole or installed through a bearing gasket. According to the above structure _, if the platform 4 performs a spherical motion on the vehicle body 2, the first pipe 21 and the second pipe 2 2 perform a relative spherical movement through the connecting pipe 50, so it is not necessary for each pipe 2 1. 2 2 and 5 0 are spherically processed to form a flexible fire rescue fluid flow path as shown in FIG. 8, and the fire rescue fluid is transferred from the vehicle body 2 side to the table 4 side. Therefore, the cost can be reduced, the relative bending angles of the first and second pipes 2 1 and 2 2 can be increased, the pressure resistance performance of the connecting portion can be improved, and the diameter of each of the pipes 2 1, 2 2 and 50 can be reduced. . In addition, the connecting pipe 50 is inserted into the first and second pipes 2 1 and 2 2 through the sealing members 5 1 and 5 2, and the connecting member 60 that surrounds the connecting pipe 50 is connected to the first and the second pipes. 2 piping 2 1 and 2 2 can perform the spherical movement, and the structure is simple; the central axis of the connecting pipe 50 passes through the center R of the spherical movement, so that the spherical movement can be performed smoothly. In addition, the stage 4 passes through the center R of the spherical motion of the carousel 2 of the vehicle body 2 and the second pipe 22 can rotate to the stage 4 at a center coaxial with the axis of revolution C. This spherical motion can be performed in a state where four pairs of vehicle bodies 2 only rotate at an arbitrary angle. In addition, the iL of the present invention is not limited to %%. For example, the piping joint of the present invention is used in equipment other than fire trucks to transport fire-fighting fluids and to clean them.
