Description of the invention (l) [Technical field to which the invention belongs] The present invention relates to a universal joint for buried pipes. [Technical background] When the conventional water pipe is buried in the buried plane, when the buried site is subsided, and when the earthquake occurs, the installed plane may be stepped. In order to prevent the bending direction, only the pressure is applied to the buried pipe. Piping and plumbing equipment are required to prevent damage. Because the two ends of the project are installed in the single but metal full-slope project < the central part of the problem. Therefore, in order to slide inside the tube of the retractable mechanism of the telescopic mechanism at the rotating part, the aforementioned rotating roll, the rotating part to the field near the difficulty machine meets a single tube two of the front installation gold, so that the universal joint ball is fitted. In the machining process, the rotation of the universal system required by the above-mentioned requirements; there is a metal head equipped with a fusion head at the end, because it must be high in order to maintain it, and it will be extended with its outward joint ball. The rotation accuracy of the two ends of the tube that controls the rotation of the tube will be deformed. The existence of the shrinkage mechanism will exist in the central part of the single tube. The "faint pearl" will provide a rotating part and rotation, and it will be installed in the central part of the single large weight. It is not used nearby. The purpose of the present invention is to solve the problem except that the shape will become larger. It is to provide the above-mentioned 'reduction of cost-saving projects without increasing the weight. Difficult mechanical processing of conventional universal joints, and elimination joints.

Description of the invention (4) In the aforementioned groove 4, the brake is fixed in the single tube 1 with a spring 5. The outer surface of the rotating sphere 2 is a spherical support 7 composed of natural rubber, synthetic rubber, synthetic resin or a soft material. The rotating sphere 2 is embedded in the spherical recess 11 of the sleeve 10 outside the rotating sphere 2 The surface is in sliding contact with the inner surface of the spherical recessed portion 11 of the sleeve, and is maintained by the support ring 12 embedded in the opening portion of the sleeve 10. In addition, 8 and 9 are covering rings, and the hardness of the spherical support body 7 is preferably the international rubber hardness IRHD50 or more. When using the aforementioned universal joint for piping, the not-shown connected pipe bodies are provided at both ends of the universal joint, and the flanges of the connected pipe body and the protrusions on the sleeve 10 of the universal joint are respectively provided. The flange 14 is connected, and the connected pipe body is connected to a single pipe to complete the piping work. The aforementioned piping operation only needs to connect the flange 14 to the flange of the connected pipe body, so the operation can be completed in a very short time. In the foregoing case, 'the sleeve 10 is moved along the inner and outer directions of the single pipe 1 according to the size of the interval between the flanges of the connected pipe bodies' so as to correspond to the aforementioned flange interval. At this time, in the groove 4 of the rotating sphere 2, the brake 6 of the single tube 丨 will start to slide. As shown in FIG. 1 and FIG. 2, the minimum interval is shown. In the case of the largest gap, the inside of the groove 4 will be fitted into the brake 6. The axis A—A of the two connected pipe bodies shown in FIG. 3, and the axis BB of the rotating sphere 2 at the angle α intersect with each other. Here again In this case, the rotating sphere 2 is centered at 10 centimeters c. The outer surface of the spherical support 7 of the rotating sphere 2 will slide on the inner surface of the spherical recess 11 of the ^, and the rotating sphere 2 will be as desired.

Description of the invention (5) Rotating at an angle, the piping operation as mentioned above can be completed quite simply and in a short time. In the above embodiment, the angle between the single tube 丨 and the sleeve 10 is 15 degrees', but the present invention is not limited to this. Fig. 4 shows the second embodiment of the present invention. This embodiment is green and has some parts that are the same in the first embodiment. These types of parts are added with the same matches and their descriptions are omitted. The different parts are mainly described. In the present invention to the second embodiment, the single tube 1 is divided into a plurality of single tubes], and the i-shaped configuration is 2). On the one hand, the inner surface of the single tube 2 is formed with an axial direction: :: a slot 15 provided in the other One single tube 丨-;! The ring-shaped protrusion 16 on the front end is slidingly fitted to the groove 15, and the protrusion 1δ will be fitted with the stopper 17 provided at the mouth to prevent the two single pipes i, 丨 _2 Two to each other: The protrusions 16 are maintained at the shortest length by the square pipes 1,2, which are fitted into the end portions of the grooves 5 and 5. Earlier the present invention was a universal joint as mentioned above. Because the two ends of the single tube were slid into a rotating sphere, the outside of the rotating sphere was embedded with a spherical support made of soft β, and the rotating ball system was embedded in the spherical concave of the sleeve. J = The outer surface is in contact with the inner surface of the spherical recess of the sleeve, so it can reduce the difficulty of the expensive engineering. Besides its shape will change, it will not increase the weight. In addition, the phenomenon of sinking and floating under the ground also has considerable compatibility, which can correspond to the changes in the settlement of the site and the damage of the pipe. In addition, due to the rotating part's advantage: the soft material enables the accuracy of the processing to be smoothly and accurately. The effect of mass production. Serve him enough
