Description

Technical Field

[0001] The utility model relates to a connecting structure for inlet and outlet water pipes, belonging to the field of water pipe installation. Background Art

[0002] A water pipe is a pipeline system for transporting water, usually made of various materials such as plastics (PVC, PE) or metals (copper, galvanized steel pipe, stainless steel), etc. It is widely used in residential buildings, commercial buildings, industrial facilities and public water supply systems to transport water from the water source to the places where users need it.

[0003] In the prior art, the common inlet water pipe and outlet water pipe made of metal usually use flanges to connect the two. That is, when connecting, the two water pipes are spliced together, and then bolts are used to fix the inlet water pipe and the outlet water pipe. However, when the installation positions required for the inlet water pipe and the outlet water pipe are relatively narrow, for example, one side of the inlet water pipe and the outlet water pipe is close to the wall, at this time, it is difficult for the bolts to penetrate into the installation holes on the surface of the flange close to the wall side, thereby increasing the difficulty of connecting the inlet water pipe and the outlet water pipe. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a connecting structure for inlet and outlet water pipes to solve the problem that when the installation positions required for the inlet water pipe and the outlet water pipe using the flange connection method are relatively narrow, for example, one side of the inlet water pipe and the outlet water pipe is close to the wall, at this time, it is difficult for the bolts to penetrate into the installation holes on the surface of the flange close to the wall side, thereby increasing the difficulty of connecting the inlet water pipe and the outlet water pipe as mentioned in the above background art.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions: A connecting structure for inlet and outlet water pipes includes a pipe body. An installation disk is rotatably connected to the surface of the pipe body. A guide rail is fixedly connected to the surface of the pipe body on one side of the installation disk. A number of sliders are slidably connected in the guide rail. The sliders are fixedly connected to the installation disk. A number of installation holes are opened on the surface of the installation disk above the guide rail. Installation bolts are inserted into the installation holes. Installation nuts are threadedly connected to the surfaces of the installation bolts.

[0006] Furthermore, a first limiting plate is fixedly connected to the surface of the pipe body on one side of the guide rail. A second limiting plate is fixedly connected to the outside of the installation disk. Limiting holes are opened on the surfaces of the first limiting plate and the second limiting plate. Limiting bolts are inserted into the limiting holes. Limiting nuts are threadedly connected to the surfaces of the limiting bolts.

[0007] Furthermore, a sealing ring is fixedly connected to the surface of the pipe body on one side of the installation disk. A sealing groove is opened on one side of the installation disk close to the sealing ring.

[0008] Furthermore, the diameter of the guide rail is smaller than that of the mounting disc, the length of the mounting bolt is greater than the sum of the lengths of the two mounting discs, and the length of the limit bolt is greater than that of the mounting bolt.

[0009] Furthermore, the slider is in an "L" shape, and a plurality of the sliders are distributed in a circular array centered on the mounting disc.

[0010] Furthermore, the diameter of the sealing groove is the same as that of the sealing ring, and the sealing ring fits with the sealing groove.

[0011] Advantages of the present utility model: When connecting the water inlet pipe and the water outlet pipe, the two mounting discs respectively fixed on the surfaces of the water inlet pipe and the water outlet pipe are butted together, and it is ensured that a plurality of mounting holes formed on the surfaces of the two mounting discs can be aligned. The water inlet pipe and the water outlet pipe can be connected together through the mounting bolts, the mounting holes and the mounting nuts. When the installation positions of the water inlet pipe and the water outlet pipe are relatively narrow, rotate the mounting disc, and cooperate with the slider and the guide rail to rotate the mounting hole for inserting the mounting bolt to the side close to the user, so as to facilitate the installation of the water inlet pipe and the water outlet pipe when the installation positions of the water inlet pipe and the water outlet pipe are relatively narrow.

[0012] When rotating the mounting disc, the cooperation of the sealing groove and the sealing ring can ensure the sealing performance between the mounting disc and the pipe body, which is beneficial to improving the sealing performance of the connection between the water inlet pipe and the water outlet pipe.

[0013] After all the mounting bolts are fixed to the mounting holes through the mounting nuts, rotate the mounting disc until the second limiting plate faces the first limiting plate, and cooperate with the limiting hole, the limiting bolt and the limiting nut to fix the mounting disc on the surface of the pipe body, so as to prevent the mounting disc from rotating along the surface of the pipe body due to external force during the use of the water inlet pipe and the water outlet pipe.

Specific implementation mode

[0019] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0020] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a connection structure for inlet and outlet water pipes, including a pipe body 1, a mounting plate 2 is rotatably connected to the surface of the pipe body 1, a guide rail 3 is fixedly connected to the surface of the pipe body 1 on one side of the mounting plate 2, a plurality of sliders 4 are slidably connected in the guide rail 3, the sliders 4 are fixedly connected to the mounting plate 2, a plurality of mounting holes 5 are opened on the surface of the mounting plate 2 above the guide rail 3, a mounting bolt 6 is passed through the mounting hole 5, and a mounting nut 7 is threadedly connected to the surface of the mounting bolt 6.

[0021] When connecting the inlet pipe and the outlet pipe, the two mounting plates 2 respectively fixed on the surfaces of the inlet pipe and the outlet pipe are butted together and it is ensured that a plurality of mounting holes 5 opened on the surfaces of the two mounting plates 2 can be aligned. The inlet pipe and the outlet pipe can be connected together through the mounting bolt 6, the mounting hole 5 and the mounting nut 7. When the installation positions of the inlet pipe and the outlet pipe are relatively narrow, rotate the mounting plate 2, and cooperate with the slider 4 and the guide rail 3 to rotate the mounting hole 5 where the mounting bolt 6 needs to be inserted to the side close to the user, so as to facilitate the installation of the inlet pipe and the outlet pipe when the installation positions of the inlet pipe and the outlet pipe are relatively narrow.

[0022] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a first limiting plate 8 is fixedly connected to the surface of the pipe body 1 on one side of the guide rail 3, a second limiting plate 9 is fixedly connected to the outside of the mounting plate 2, limiting holes 10 are opened on the surfaces of the first limiting plate 8 and the second limiting plate 9, a limiting bolt 11 is passed through the limiting hole 10, and a limiting nut 12 is threadedly connected to the surface of the limiting bolt 11. After all the mounting bolts 6 are fixed to the mounting holes 5 through the mounting nuts 7, rotate the mounting plate 2 until the second limiting plate 9 faces the first limiting plate 8, and cooperate with the limiting hole 1, the limiting bolt 11 and the limiting nut 12 to fix the mounting plate 2 on the surface of the pipe body 1, so as to prevent the mounting plate 2 from rotating along the surface of the pipe body 1 due to external force during the use of the inlet pipe and the outlet pipe.

[0023] A sealing ring 13 is fixedly connected to one side of the surface of the pipe body 1 located on the side of the mounting disc 2, and a sealing groove 14 is formed on one side of the mounting disc 2 close to the sealing ring 13. When the mounting disc 2 is rotated, the sealing groove 14 and the sealing ring 13 can ensure the sealing performance between the mounting disc 2 and the pipe body 1, which is beneficial to improving the sealing performance of the connection between the water inlet pipe and the water outlet pipe.

[0024] The diameter of the guide rail 3 is smaller than the diameter of the mounting disc 2, the length of the mounting bolt 6 is greater than the sum of the lengths of the two mounting discs 2, and the length of the limit bolt 11 is greater than the length of the mounting bolt 6. The diameter of the guide rail 3 being smaller than the diameter of the mounting disc 2 ensures that the guide rail 3 does not obstruct the insertion of the mounting bolt 6 into the mounting hole 5 when connecting the water inlet pipe and the water outlet pipe. The length of the mounting bolt 6 being greater than the sum of the lengths of the two mounting discs 2 ensures that the mounting bolt 6 can smoothly pass through the two mounting discs 2 respectively fixed on the surfaces of the water inlet pipe and the water outlet pipe and be connected to the mounting bolt 6. The length of the limit bolt 11 being greater than the length of the mounting bolt 6 ensures that the mounting disc 2 will not be blocked from rotating due to the too small distance between the first limit plate 8 and the second limit plate 9 during the process of driving the mounting bolt 6 fixed on its surface to rotate.

[0025] The slider 4 is in an "L" shape, and a number of sliders 4 are distributed in a circular array centered on the mounting disc 2. The slider 4 being in an "L" shape and a number of sliders 4 being distributed in a circular array centered on the mounting disc 2 can provide guidance for the rotation trajectory of the mounting disc 2.

[0026] The diameter of the sealing groove 14 is the same as the diameter of the sealing ring 13, and the sealing ring 13 fits with the sealing groove 14. The diameter of the sealing groove 14 being the same as the diameter of the sealing ring 13 and the sealing ring 13 fitting with the sealing groove 14 ensure that the sealing groove 14 can fit tightly with the sealing ring 13, thus effectively improving the sealing performance between the mounting disc 2 and the pipe body 1.

[0027] **Detailed implementation method**: When connecting the water inlet pipe and the water outlet pipe, first, butt the two mounting plates 2 respectively fixed on the surfaces of the water inlet pipe and the water outlet pipe together and ensure that a number of mounting holes 5 opened on the surfaces of the two mounting plates 2 can be aligned. Then, insert the mounting bolts 6 into the mounting holes 5. Next, slip the mounting nuts 7 onto the surfaces of the mounting bolts 6 and use a wrench or the like to turn them. As the mounting nuts 7 rotate continuously, they will gradually move towards the mounting plates 2 until they are close to one side of the mounting plates 2. Repeating the above steps can connect the water inlet pipe and the water outlet pipe together. When the installation positions of the water inlet pipe and the water outlet pipe are relatively narrow, for example, one side of the water inlet pipe and the water outlet pipe is close to the wall, it is difficult for the mounting bolts 6 to penetrate into the mounting holes 5 on the side of the mounting plate 2 close to the wall. At this time, the mounting plate 2 can be rotated. The mounting plate 2 will drive a number of sliders 4 fixed on its surface to slide in the guide rails 3, thereby driving a number of mounting holes 5 to move synchronously, and the mounting holes 5 that need to insert the mounting bolts 6 can be rotated to the side close to the user, so as to facilitate the installation of the water inlet pipe and the water outlet pipe when the installation positions of the water inlet pipe and the water outlet pipe are relatively narrow;

[0028] When rotating the mounting plate 2, the sealing groove 14 opened on one side of the mounting plate 2 will rotate synchronously along the surface of the sealing ring 13. Since the sealing ring 13 is in close fit with the sealing groove 14, the sealing performance between the mounting plate 2 and the pipe body 1 can be ensured, which is conducive to improving the sealing performance of the connection between the water inlet pipe and the water outlet pipe;

[0029] After all the mounting bolts 6 are fixed to the mounting holes 5 through the mounting nuts 7, rotate the mounting plate 2 until the second limiting plate 9 fixed on the outside of the mounting plate 2 is directly opposite to the first limiting plate 8 fixed on the surfaces of the water inlet pipe and the water outlet pipe. At this time, the limiting holes 10 opened on the surface of the second limiting plate 9 will be on the same horizontal line as the limiting holes 10 opened on the surface of the first limiting plate 8. Then, insert the limiting bolts 11 into the limiting holes 10. Next, slip the limiting nuts 12 onto the surfaces of the limiting bolts 11 and turn them. As the limiting nuts 12 rotate continuously, they will gradually move towards the first limiting plate 8 until they are close to one side of the first limiting plate 8, and the mounting plate 2 can be fixed on the surface of the pipe body 1, thus preventing the mounting plate 2 from rotating along the surface of the pipe body 1 due to external forces during the use of the water inlet pipe and the water outlet pipe.

[0030] In addition, it should be understood that although this specification is described according to the implementation manners, not every implementation manner only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
