[0002] The existing tee joint structure, such as a patent application filed by the applicant on November 07, 2022, with a patent application number of 202222988289.5 and a patent name of an anti-electric leakage tee pipe fitting for water supply, specifically discloses: including a tee pipe made of plastic, the tee pipe has a first interface, a second interface and a third interface that communicate with each other, the central axes of the second interface and the third interface coincide, the central axis of the first interface is perpendicular to the central axes of the second interface and the third interface, the first interface is provided with a metal joint made of metal material, the metal joint is integrally injection molded with the tee pipe, the metal joint has internal threads, a through groove is provided on one side surface of the tee pipe and at the position of the first interface, through this through groove, the outer side surface of the metal joint is in contact with the outside, a rib is provided on the outer side surface of the metal joint and at the position of the through groove, sliding grooves are provided on the opposite side surfaces of the through groove, a wire mounting seat is detachably provided at the through groove, elastic feet matched with the sliding grooves are provided on the periphery of the wire mounting seat, a wire mounting assembly and a metal sheet with a conductive function are provided on the wire mounting seat, when the wire mounting seat is clamped at the through groove, the free end of the metal sheet abuts against the rib of the metal joint. By integrally molding the plastic tee pipe and the metal joint made of metal material, when the metal joint connects the pipe fittings, it can ensure the connection tightness during the alternating use of cold and hot water in the pipe fittings, improve the durability, and can avoid the problem of scalding caused by using a metal joint.

[0003] However, in water-using areas such as bathrooms, kitchens, balconies and terraces, during decoration, due to the inability to accurately control the thickness of the wall finish surface in the early stage, the embedding depth of the tee joint is entirely constructed by experience, resulting in the connection end surface of the internal thread interface of the tee joint being difficult to be on the same finish surface as the tile laying surface. When the distance between the connection end surface of the internal thread interface of the tee joint and the tile laying surface is too large, it is easy to cause mud to contaminate the connection end surface of the internal thread interface of the tee joint when fitting the tiles, and even pour into the internal thread interface. Subsequently, it is necessary to further cut and clean the solidified mud around, the connection convenience is poor, and the residual mud is likely to reduce the connection tightness with the pipe fittings, resulting in leakage. Summary of the Utility Model

[0004] Therefore, in view of the above problems, the utility model provides a tee joint with an easily cuttable extension part, which mainly solves the problems of poor connection convenience between the embedded tee joint and the pipe fittings and easy leakage in the prior art.

And during use, through the convex part provided in the flow channel, and the first guiding surface and the second guiding surface with a curved surface structure are provided on the convex part, which plays a guiding role.

[0015] The present utility model will be further described below in conjunction with the drawings and the detailed description of the embodiments.

[0016] The embodiment of the present utility model is as follows:

[0017] Reference Figure 1 、 Figure 2 And Figure 3As shown in the figure, a tee connector with an easily cuttable extension includes a tee pipe 1 made of plastic. The tee pipe 1 has a first interface 101, a second interface 102, and a third interface 103. The central axes of the second interface 102 and the third interface 103 coincide. The central axis of the first interface 101 is perpendicular to the central axes of the second interface 102 and the third interface 103. A flow channel 104 communicating the first interface 101, the second interface 102, and the third interface 103 is provided inside the tee pipe 1. A metal joint 2 made of metal material is provided at the first interface 101. The metal joint 2 is integrally injection-molded with the tee pipe 1. The metal joint 2 has an internal thread 3. A boss 4 is convexly provided on the outer side surface of the metal joint 2. A threaded hole (not shown in the figure) is provided on the boss 4. A wire joint 6 is provided on the boss 4 by screwing a screw 5 into the threaded hole. An extension 7 in a ring structure extends outward along the outer edge of the end face of the first interface 101. The length dimension of the extension 7 is 5 mm to 80 mm, preferably 30 mm. The thickness dimension of the extension 7 is smaller than the thickness dimension of the first interface 101, so that an annular end face 105 is formed at the first interface 101. A raised portion 8 is provided in the flow channel 104 and between the second interface 102 and the third interface 103. A first guide surface 81 with a curved surface structure and facing the second interface 102 and a second guide surface 82 with a curved surface structure and facing the third interface 103 are provided on the raised portion 8.

[0018] In this tee connector with an easily cuttable extension, through the extension 7 in a ring structure provided at the first interface 101, the length of the first interface 101 can be extended during embedding, preventing mud from contaminating and blocking the first interface 101, improving the cleanliness of the first interface 101, and after fitting the tiles, by cutting the extension, it can be made to be on the same finished surface as the tile laying surface, improving the aesthetics. At the same time, the extension facilitates the positioning and installation of the pipe fittings, enhancing the convenience of connecting with the pipe fittings later. Moreover, the cooperation between the extension 7 and the end face of the first interface 101 further improves the sealing performance of the connection with the pipe fittings, avoiding leakage. And during use, through the raised portion 8 provided in the flow channel 104, and the first guide surface 81 and the second guide surface 82 with curved surface structures provided on the raised portion 8, a guiding effect is achieved. When the valve connected at the first interface 101 is opened, the first guide surface 81 of the raised portion 8 realizes the smooth water flow effect, increasing the water flow rate through the valve and reducing the water flow noise.

[0019] Moreover, the ratio of the distance dimension between the convex portion 8 and the second interface 102 to the distance dimension between the convex portion 8 and the third interface 103 is 5-6:4, preferably 5:4, such that the setting of the convex portion 8 is offset from the central axis of the first interface 101 and is closer to the side of the third interface 103. In this way, the water flow entering from the second interface 102 can utilize the first guiding surface 81 to achieve a guiding effect with a larger flow rate, further enhancing the water flow rate through the valve.

[0020] In this embodiment, an anti-slip convex block 9 is provided on the outer surface of the tee pipe 1 and near the first interface 101 to improve the convenience of installation.

[0021] Furthermore, an annular groove 10 is provided on the end face of the first interface 101 and near the extension portion 7. A through hole 11 is provided on the side surface of the annular groove 10 and is connected to the outside. When the pipe fitting is in close fit with the extension portion 7, it is convenient to discharge the internal air and dust into the annular groove 10 and discharge them through the through hole 11, maintaining the cleanliness of the inner surface of the extension portion 7 and the end face of the first interface 101, and further enhancing the connection tightness.

[0022] Furthermore, the wire connector 6 includes a first fixing portion 61 having a plate-like structure and a second fixing portion 62 having a ring-like structure. The first fixing portion 61 and the second fixing portion 62 are integrally connected. A connection hole for the screw 5 to pass through is provided on the first fixing portion 61, facilitating the installation of the wire. During use, the wire can be inserted into the ring-like second fixing portion 62, then pressed and fixed, and the wire connector 6 is fixed by screwing the screw 5 into the threaded hole. Its installation convenience is good, and the tee pipe 1 made of plastic combined with the metal joint 2 connected to the ground wire through the wire can play an anti-electric shock role.
