Description

Technical Field

[0001] The utility model relates to the field of pipe connectors, in particular to a two-way connector with an easily cut extension portion. Background Art

[0002] The structure of the existing two-way connector, such as Chinese patent application number: 202022344466.7, discloses an extended internal thread elbow, which specifically discloses a bend pipe body, wherein the bend pipe body includes a first connecting part and a second connecting part integrally formed of plastic, the first connecting part is an extended pipe section, the first connecting part has a first interface, the second connecting part has a second interface, the bend pipe body has a flow channel connecting the first interface and the second interface, the first interface is provided with a metal joint with an internal thread made of metal material and in a tubular shape, the metal joint is integrally injection molded with the bend pipe body, a convex ring is provided around the inner surface of the metal joint and near the lower end, the outer side surface of the metal joint is provided with a protrusion along its radial direction, the upper surface of the protrusion is provided with a threaded hole along the axial direction of the metal joint, and the outer surface of the protrusion is provided with a through hole along the radial direction of the metal joint, and the through hole is connected to the threaded hole. The first connecting part with an extended pipe section and the second connecting part are integrally formed into a bent pipe body, so that the connection strength of the bent pipe body is guaranteed. Since the first connecting part is an extended pipe section, it can adapt to special needs during installation and is free from the need to connect the extended end, thereby improving its installation convenience. At the same time, a through hole and a threaded hole are provided on the protrusion of the metal joint and are in a right-angle connecting structure. When in use, the wire can be inserted into the through hole and the screw can be screwed into the threaded hole to tighten the wire, so it is easy to install.

[0003] However, in water-using areas such as bathrooms, kitchens, balconies and terraces, the thickness of the wall finish cannot be accurately controlled in the early stage of renovation, and the embedded depth of the water return ring is constructed entirely based on experience, resulting in the connection end face of the inner thread interface of the water return ring being difficult to be on the same finish surface as the tile paving surface. When the connection end face of the inner thread interface of the water return ring is too far away from the tile paving surface, it is easy to cause mud to contaminate the connection end face of the inner thread interface of the water return ring when the tiles are fitted, or even pour into the inner thread interface. Subsequently, the surrounding solidified mud needs to be further cut and cleaned, resulting in poor connection convenience, and the residual mud can easily reduce the sealing of the connection with the pipe fittings, causing leakage; and leakage at the connection point can easily penetrate into the wall, causing leakage in the house, requiring the wall to be chiseled open for replacement, resulting in poor convenience of use. Utility Model Content

[0004] Therefore, in order to solve the above problems, the present invention provides a two-way connector with an easily cut extension portion, which mainly solves the problem in the prior art that the pre-buried two-way connector and the pipe are poorly connected and easily leak.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Furthermore, the annular end surface is concavely provided with a strip groove connected to each guide groove.

[0008] Furthermore, an anti-slip bump is provided on the outer surface of the two-way pipe body near the first interface.

The first fixing portion and the second fixing portion are integrally connected, and the first fixing portion is provided with a connection hole for a screw to pass through.

[0010] Furthermore, the two-way pipe body is a bent pipe, and a buffer portion with a curved structure is provided in the flow channel and between the first joint and the second joint. The curvature of the buffer portion is smaller than the curvature of the outer surface of the two-way pipe body corresponding to the buffer portion.

[0011] Furthermore, a limiting convex ring is provided on the inner surface of the second interface.

[0012] By adopting the above-mentioned technical solution, the beneficial effects of the utility model are as follows: the two-way connector with an easy-to-cut extension part can extend the length of the first interface during pre-embedding through the extension part in a ring structure arranged at the first interface, thereby preventing mud pollution and clogging of the first interface, improving the cleanliness of the first interface, and cutting the extension part after the tiles are attached so that it is on the same finished surface as the tile paving surface, thereby improving the aesthetics. At the same time, the extension part facilitates the positioning and installation of the pipe fittings, and the convenience of subsequent connection with the pipe fittings is improved. The extension part cooperates with the end face of the first interface, thereby further improving the sealing of the connection with the pipe fittings, improving the sealing of the connection, and avoiding leakage. During use, due to aging and leakage at the connection between the first interface and the pipe fitting, the leaked water is diverted out of the wall through the guide groove on the extension part, which is convenient for users to discover and replace in time, thereby improving the convenience of use.

The extension portion 6 of the annular structure has a length dimension of 5mm to 80mm, preferably 45mm, and a thickness dimension of the extension portion 6 is smaller than the thickness dimension of the first interface 11, so that an annular end face 7 is formed at the first interface 11, and at least three guide grooves 8 are provided on the inner surface of the extension portion 6 along its axial direction, preferably four, so that a guide portion 61 is formed on the extension portion 6 at the guide groove 8, and a connecting portion 62 is formed between two adjacent guide portions 61, and the thickness dimension of the connecting portion 62 is 1 to 3mm larger than the thickness dimension of the guide portion 61, preferably 2mm, and the outer end of the guide groove 8 is connected to the outside world.

[0019] The two-way connector with an easy-to-cut extension portion can extend the length of the first interface 11 during pre-embedding through the extension portion 6 in a ring-shaped structure provided at the first interface 11, thereby preventing mud pollution and clogging of the first interface 11, improving the cleanliness of the first interface 11, and cutting the extension portion 6 after the tiles are attached so that it is on the same finished surface as the tile paving surface, thereby improving the aesthetics. At the same time, the extension portion 6 facilitates the positioning and installation of the pipe fittings, and the convenience of subsequent connection with the pipe fittings is improved. The extension portion 6 cooperates with the end face of the first interface 11, so that the sealing of the connection with the pipe fittings is further improved, thereby improving the sealing of the connection and avoiding leakage. During use, due to aging and leakage at the connection between the first interface 11 and the pipe fitting, the leaked water is diverted out of the wall through the guide groove 8 on the extension portion 6, which is convenient for users to discover and replace in time, thereby improving the convenience of use.

[0020] In addition, a strip groove 9 is recessed on the annular end surface 7 and connected to each guide groove 8. On the one hand, it is convenient to guide the leaking water.
