[0034] Embodiment 1

[0035] This embodiment is suitable for quick installation of pipelines. Compared with the installation method of brushing glue or hot melting, this embodiment has the advantage of being environmentally friendly, and the operation is simple and fast, which is convenient for users to install by themselves.

[0036] See also Figure 1 and Figure 2 This embodiment provides a three-way connector 10 . Specifically, the three-way connector 10 includes a body 100 and a quick pipe clamp 200 .

[0037] See also Figure 3 and Figure 4 The body 100 is provided with a water inlet channel 110 , a first water outlet channel 120 and a second water outlet channel 130 , and the water inlet channel 110 is connected to at least one of the first water outlet channel 120 and the second water outlet channel 130 .

[0038] In this embodiment, the main body 100 is injection molded from ABS material, and the manufacturing cost is low.

[0039] There are three communication conditions. The first communication condition is that the water inlet channel 110 is connected to the first water outlet channel 120. The second communication condition is that the water inlet channel 110 is connected to the second water outlet channel 130. The third communication condition is that the water inlet channel 110 is connected to both the first water outlet channel 120 and the second water outlet channel 130.

[0040] The first connection condition and the second connection condition indicate that the three-way connector 10 is used to connect two pipelines, and the third connection condition indicates that the three-way connector 10 is used to connect three pipelines.

[0041] In actual use, the water inlet direction of the water inlet channel 110 and the water outlet direction of the first water outlet channel 120 are parallel to each other. Taking the water inlet direction of the water inlet channel 110 as the horizontal direction, the water outlet direction of the first water outlet channel 120 is also the horizontal direction.

[0042] The water inlet direction of the water inlet channel 110 and the water outlet direction of the second water outlet channel 130 are perpendicular to each other. Taking the water inlet direction of the water inlet channel 110 as the horizontal direction, the water outlet direction of the second water outlet channel 130 is the vertical direction.

[0043] The number of the quick pipe clamps 200 is at least two, one of which is installed in the water inlet channel 110 , and the other quick pipe clamps 200 are installed in the first water outlet channel 120 and / or the second water outlet channel 130 .

[0044] When the water inlet channel 110 is connected to the first water outlet channel 120 , there are two quick pipe clamps 200 , one of which is installed in the water inlet channel 110 , and the other is installed in the first water outlet channel 120 .

[0045] When the water inlet channel 110 is connected to the second water outlet channel 130 , there are two quick pipe clamps 200 , one of which is installed in the water inlet channel 110 , and the other is installed in the second water outlet channel 130 .

[0046] It is understandable that when the three-way connector 10 is used to connect two pipelines, the first water outlet channel 120 or the second water outlet channel 130 needs to be sealed. Specifically, the three-way connector 10 also includes an end cover 300, which is disposed on the first water outlet channel 120 or the second water outlet channel 130 where the quick pipe clamp 200 is not installed.

[0047] When the water inlet channel 110 is connected to the first water outlet channel 120 and the second water outlet channel 130 at the same time, the number of quick pipe clamps 200 is three, one quick pipe clamp 200 is installed in the water inlet channel 110, one quick pipe clamp 200 is installed in the first water outlet channel 120, and another quick pipe clamp 200 is installed in the second water outlet channel 130.

[0048] See also Figure 4 and Figure 5 Each quick pipe clamp 200 includes a first clamping portion 210 and a second clamping portion 220, and the first clamping portion 210 and the second clamping portion 220 define a clamping cavity; in actual use, since the drainage pipeline is generally a round pipe, the clamping cavity can be set in a circular shape in this embodiment.

[0049] When the quick pipe clamp 200 is installed in the water inlet channel 110, the clamping cavity is connected to the water inlet channel 110; when the quick pipe clamp 200 is installed in the first water outlet channel 120, the clamping cavity is connected to the first water outlet channel 120; when the quick pipe clamp 200 is installed in the second water outlet channel 130, the clamping cavity is connected to the second water outlet channel 130.

[0050] In some embodiments, each quick tube clamp 200 further includes a first cut-in portion 230 and a second cut-in portion 240 , which are connected end to end along the radial direction of the clamping cavity, and the first cut-in portion 230 is located at the first clamping portion 210 , and the second cut-in portion 240 is located at the second clamping portion 220 .

[0051] In this embodiment, the first cutting portion 230 and the second cutting portion 240 can be configured as stainless steel blades with blades. In this way, after the first clamping portion 210 and the second clamping portion 220 clamp the pipeline, the first cutting portion 230 and the second cutting portion 240 can be embedded in the pipeline through the blades to achieve a fixed connection between the quick pipe clamp 200 and the pipeline, and the first cutting portion 230 and the second cutting portion 240 can achieve seamless docking under the action of external force, thereby simplifying the pipeline installation steps and reducing the difficulty of installation.

[0052] In some embodiments, each quick tube clamp 200 further includes a first sealing portion 250 and a second sealing portion 260, wherein the first sealing portion 250 and the second sealing portion 260 are connected end to end along the radial direction of the clamping cavity, and the first sealing portion 250 is located at the first clamping portion 210 and is arranged side by side with the first cut-in portion 230, and the second sealing portion 260 is located at the second clamping portion 220 and is arranged side by side with the second cut-in portion 240.

[0053] The first sealing portion 250 and the second sealing portion 260 are connected end to end to form a sealing ring. After the blade is embedded in the pipeline, the sealing ring performs a waterproof seal on the pipeline.

[0054] As for the fixing of the first clamping part 210 and the second clamping part 220, the present embodiment can be set as follows: the first clamping part 210 is provided with a hook 211, and the second clamping part 220 is provided with a slot 221, and the slot 221 is opened on the surface of the second clamping part 220. The hook 211 is placed in the slot 221, so that the first clamping part 210 and the second clamping part 220 are clamped.

[0055] In this embodiment, the hook 211 and the slot 221 cooperate to prevent the quick pipe clamp 200 from loosening. After being installed in place, the first clamping part 210 and the second clamping part 220 are seamlessly connected.

[0056] Since the slot 221 is provided on the surface of the second clamping portion 220 , if the quick pipe clamp 200 needs to be dismantled and repaired, the operator can directly press the hook 211 downward through the slot 221 , and then pull the first clamping portion 210 to move the hook 211 out of the slot 221 , thereby separating the first clamping portion 210 from the second clamping portion 220 .

[0057] For further information, please refer to Figure 2 and Figure 4 The three-way joint 10 also includes a check member 400. The main body 100 is also provided with a water passage chamber 140. The water passage chamber 140 is respectively connected to the first water outlet channel 120 and the second water outlet channel 130. The check member 400 is installed in the water passage chamber 140, and the check member 400 is rotatably connected relative to the main body 100. When the check member 400 is rotated into place, the water inlet channel 110 is disconnected from the water passage chamber 140.

[0058] Specifically, here is a detailed description of how to install the anti-return member 400. The body 100 is further provided with a mounting hole 150, and the anti-return member 400 is provided with a rotating shaft 410, which passes through the mounting hole 150 and extends along a water inlet direction perpendicular to the water inlet channel 110.

[0059] When water flows into the water inlet channel 110, the check member 400 rotates in the direction away from the water inlet channel 110 (i.e., rotates upward) under the action of water pressure, thereby opening the connection between the water inlet channel 110 and the water passage chamber 140, realizing the drainage function. When the water pressure in the water inlet channel 110 is not sufficient to open the check member 400, the check member 400 rotates downward to its original position under the action of gravity, thereby disconnecting the connection between the water inlet channel 110 and the water passage chamber 140.

[0060] Based on the above content, this embodiment further explains the installation principle of the three-way connector 10 for connecting two pipelines as follows, wherein the water flow directions of the two pipelines are parallel to each other. For the convenience of description and understanding, the two pipelines are respectively defined as the first pipeline and the second pipeline.

[0061] S100. Reserve suitable installation space between the two pipelines.

[0062] S200. Hold the main body 100 with the left hand, and align the water inlet channel 110 with the first pipeline, and align the first water outlet channel 120 with the second pipeline.

[0063] S300. Hold the first clamping part 210 of the quick pipe clamp 200 on the left side with the right hand, and place the first clamping part 210 between the water inlet channel 110 and the first pipeline, and then hold the body 100 and the first clamping part 210 with the left hand at the same time.

[0064] S400. Hold the second clamping part 220 of the left quick pipe clamp 200 with the right hand, and dock and fix the second clamping part 220 with the first clamping part 210 to complete the installation of the first quick pipe clamp 200.

[0065] S500. Similarly, repeat S300 and S400 to install the right quick pipe clamp 200 between the body 100 and the second pipe.

[0066] S600 . Cover the end cover 300 on the second water outlet channel 130 .
