[0042] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0043] refer to Figures 1 to 10 As shown, the utility model discloses a multi-channel connection structure, including a multi-way joint 1, a water distribution connection assembly 2, a press buckle 3, an outer tube 4 and an inner tube 5;

[0044] The multi-way connector 1 includes a first interface 11, a second interface 12 and at least one third interface 13;

[0045] The water-dividing connection assembly 2 is movably and sealingly rotatably fitted in the first interface 11, in which a first flow channel 21 and a second flow channel 22 corresponding to the third interface 13 are provided; the peripheral surface of the water-dividing connection assembly 2 is provided with a water-passing annular groove 23 corresponding to the second flow channel 22, and a rotating annular groove 24; the first end of the first flow channel 21 is communicated with the second interface 12, and the first end of the second flow channel 22 is communicated with the water-passing annular groove 23;

[0046] The pressing buckle 3 is elastically fitted on the surface of the first interface 11 and embedded in the rotating annular groove 24 to achieve axial limitation of the water-dividing connection assembly 2, so that the water-passing annular groove 23 is arranged opposite to the corresponding third interface 13, so as to maintain the second flow channel 22 and the third interface 13 in communication;

[0047] The outer tube 4 is sleeved on the inner tube 5 , and the outer tube 4 is communicated with the second end of the first flow channel 21 , and the inner tube 5 is communicated with the second end of the second flow channel 22 .

[0048] Through the above scheme, the utility model assembles the outer tube 4 and the inner tube 5 with the water-dividing connection assembly 2 in the form of a "tube in a tube", and waterways are formed inside the inner tube 5 and between the inner tube 5 and the outer tube 4, respectively, which reduces the space occupied by the tube body. At the same time, the outer tube 4 and the inner tube 5 are both connected to the water-dividing connection assembly 2, and both remain relatively fixed during the installation process, which can avoid the pipe blocking phenomenon; the water-dividing connection assembly 2 is limited by the pressing buckle 3 after being inserted along the axial direction of the first interface 11, which is simple to operate and quick and convenient to install. The cooperation between the pressing buckle 3 and the rotating annular groove 24 ensures that the water-dividing connection assembly 2, the outer tube 4 and the inner tube 5 as a whole can rotate freely in the first interface 11, and keeps the water-passing annular groove 23 always facing the corresponding third interface 13, and maintains the connection relationship between the inner tube 5 / the second flow channel 22 and the third interface 13.

[0049] It is understandable that the cooperation between the pressing buckle 3 and the rotating ring groove 24 to achieve the limitation between the water-dividing connecting assembly 2 and the first interface 11 is a preferred implementation shown in the utility model, and other buckle connection methods that can be quickly disassembled and assembled can also be used as a substitute in other technical solutions.

[0050] In some embodiments of the present invention, the first interface 11 and the second interface 12 are coaxially arranged, and the third interface 13 is perpendicular to the first interface 11 / the second interface 12, such as T-shaped when the multi-way connector 1 is a three-way connector, and cross-shaped when the multi-way connector 1 is a four-way connector; at the same time, the first end of the first flow channel 21 is connected to the end face of the water-dividing connection assembly 2 to achieve communication with the second interface 12. In addition, according to the design of the product, the third connector buckle 13 can also be inclined to the first interface 11 / the second interface 12.

[0051] In some embodiments of the present invention, the surfaces of the second interface 12 and the third interface 13 are both installed with press buckles 3 for quickly installing and fixing the water pipes connected to the multi-way connector 1 .

[0052] In some embodiments of the utility model, the outer tube 4 and the inner tube 5 are fixedly connected to the water-dividing connection assembly 2 by riveting to ensure that the ends of the outer tube 4 and the inner tube 5 are relatively fixed to the water-dividing connection assembly 2; at the same time, when the product leaves the factory, there are fewer scattered accessories, which is more convenient for users to install by themselves.

[0053] Furthermore, in order to facilitate the riveting process of the outer tube 4, the inner tube 5 and the water-dividing connection assembly 2 during production and assembly, the water-dividing connection assembly 2 is designed to be a water-dividing core 2a, a quick connector 2b and a quick connector 2c that are coaxially connected in sequence; the first flow channel 21, the second flow channel 22 and the water-passing annular groove 23 are all arranged on the water-dividing core 2a, and the first flow channel 21 is arranged around the outer periphery of the second flow channel 22; the rotating annular groove 24 is arranged on the quick connector 2c; the water-dividing core 2a and the quick connector 2c are both movably sealed with the inner wall of the first interface 11 through the sealing ring 6; the outer tube 4 is fixedly riveted to the quick connector 2c, and the inner tube 5 is fixedly riveted to the second end of the second flow channel 22. The end of the quick connector 2c may be provided with a first riveted joint 25 for the outer tube 4 to be sleeved and riveted, and the second end of the second flow channel 22 may be provided with a second riveted joint 26 for the inner tube 5 to be sleeved and riveted.

[0054] Secondly, the connection between the water-dividing core 2a and the quick-connecting piece 2b is respectively provided with a matching first quick-connecting ring groove 27 and a first quick-connecting buckle 28, a first convex portion 29 and a first concave portion 210. The first quick-connecting ring groove 27 and the first quick-connecting buckle 28 enable the water-dividing core 2a and the quick-connecting piece 2b to be connected by quick buckling in multiple directions, and the axial limit is achieved by the cooperation of the first convex portion 29 and the first concave portion 210, so as to ensure that the water-dividing core 2a and the quick-connecting piece 2b are coaxially connected; the connection between the quick-connecting piece 2b and the quick-connecting joint 2c is respectively provided with a matching second quick-connecting ring groove 27 and a first quick-connecting buckle 28. The groove 211 and the second quick-connect buckle 212, the second protrusion 213 and the second recess 214, the second quick-connect ring groove 211 and the second quick-connect buckle 212 enable the quick-connect 2b and the quick-connect joint 2c to be connected in multiple directions by quick buckle, and the axial limit is achieved through the cooperation of the second protrusion 213 and the second recess 214, ensuring that the quick-connect 2b and the quick-connect joint 2c are coaxially connected, thereby achieving the coaxial connection of the water-dividing core 2a, the quick-connect 2b and the quick-connect joint 2c, and finally achieving the relative fixation of the outer tube 4 and the inner tube 5 through the water-dividing connection assembly 2. The quick connection between the water-dividing core 2a and the quick-connect 2b, and the quick-connect 2b and the quick-connect joint 2c can be achieved by assembling the buckle hook in the ring groove. The protrusion can be a tooth-shaped or columnar structure, and the recess corresponds to its shape.

[0055] Furthermore, the peripheral surface of the quick connector 2b is provided with a fracture 215 extending axially to both ends of the quick connector 2b, so that the radial cross section of the quick connector 2b is C-shaped, which facilitates the buckles at both ends to be properly deformed during the installation process. The peripheral surface of the quick connector 2b is provided with a clamp 8 for clamping the quick connector 2b, so that the buckles at both ends of the quick connector 2b are more tightly hooked in the corresponding annular grooves to ensure structural stability.

[0056] In some embodiments of the present invention, the above-mentioned pressing buckle 3 is provided with a limiting block 31, and the pressing buckle 3 and the multi-way connector 1 are elastically matched so that the limiting block 31 is movably embedded in the rotating ring groove 24. When the user presses the pressing buckle 3, the limiting block 31 is separated from the rotating ring groove 24 to release the axial limit of the water-dividing connection assembly 2.

[0057] In some embodiments of the present invention, a one-way valve 7 installed in the second interface 12 and / or the third interface 13 is also included, which can match more usage scenarios.

[0058] See also Figures 1 to 5 , showing the first embodiment of the utility model.

[0059] In the first embodiment, the multi-way connector 1 is a three-way connector, that is, only one third interface 13 is provided, and correspondingly only one water-passing ring groove 23 is provided.

[0060] See also Figures 6 to 10 , showing the second embodiment of the utility model.

[0061] In the second embodiment, the multi-way connector 1 is a four-way connector, that is, two third interfaces 13 are provided, and two corresponding water-passing annular grooves 23 are provided.

[0062] Generally, the two third interfaces 13 need to correspond to two second flow channels 22, that is, two inner tubes 5 need to be connected. In the second embodiment, the inner tube 5 is a single tube, and a plurality of pipelines 51 are arranged in the inner tube 5. Each pipeline 51 is respectively connected to each second flow channel 22. The single-tube inner tube 5 can avoid entanglement in the outer tube 4 due to multiple tubes.

[0063] In addition, the multi-channel connection structure can also be used in a faucet to facilitate the quick connection of the faucet water channel structure. The multi-channel connection structure can be used as a multi-way water inlet device of the faucet to connect the ends of the outer tube 4 and the inner tube 5 to the water inlet end of the faucet.
