Description

Technical Field

[0001] This utility model relates to the field of faucet connector technology, and in particular to a universal connector for bathroom hoses. Background Technology

[0002] Existing universal joints, such as Figure 4 As shown, when using a hose, the hose connector is installed at the pipe inlet, and the ball of the hose connector is installed inside the installation connector. The ball and the water inlet side of the installation connector are sealed by a ball sealing gasket. Then, the pipe inlet and threaded end mate, abutting against the ball sealing gasket to ensure a seal. However, when the hose is not in use, the installation connector usually needs to be removed. During repeated disassembly and assembly of the installation connector, scale or impurities accumulate inside over time, preventing the pipe inlet and installation connector from being fully installed. That is, the ball sealing gasket is not fully squeezed by the pipe inlet. At this time, the seal between the ball and the water inlet side cannot be effectively guaranteed. During the use of the hose, water leakage is likely to occur between the installation connector and the ball, resulting in water waste.

[0003] Therefore, there is an urgent need for a universal joint for bathroom hoses that can effectively improve the sealing effect between the installation joint and the hose joint and the ball, and avoid water waste. Utility Model Content

[0004] The purpose of this utility model is to provide a universal joint for bathroom hoses, which solves the technical problem of leakage caused by insufficient installation of universal joints in the prior art. The various technical effects of the preferred technical solution among the many technical solutions provided by this utility model are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a universal connector for bathroom hoses, including an installation connector and a hose connector. The installation connector is threaded onto the pipe opening, and the ball of the hose connector is installed inside the installation connector. It also includes:

[0007] A cover body, which is located inside the water inlet end of the mounting joint and engages with the ball joint;

[0008] A sealing gasket is located inside the mounting joint and is disposed near the water outlet side of the cover.

[0009] A retaining ring is axially engaged within the mounting joint, and a sealing gasket abuts against the cover via the retaining ring. The periphery of the cover is sealed to the inner wall of the mounting joint by the sealing gasket.

[0010] Preferably, the retaining ring includes:

[0011] Snap ring;

[0012] A plurality of spring pieces are circumferentially and equidistantly fixed to the water outlet side of the retaining ring. The spring pieces are snapped into the threaded end of the mounting joint. The retaining ring abuts against the water outlet side of the sealing gasket through the plurality of spring pieces.

[0013] Preferred options also include:

[0014] A groove is formed on the side wall of the mounting joint and located between the threaded section and the water inlet end of the mounting joint. The inner diameter of the groove is larger than the minor diameter of the threaded section.

[0015] Preferably, the cover includes:

[0016] The lower cover ring, wherein the water inlet side of the lower cover ring is adapted to fit inside the water inlet end of the mounting connector;

[0017] The upper cover ring abuts against the water inlet side of the sealing gasket, and the ball joint is disposed between the upper cover ring and the lower cover ring.

[0018] Preferably, the cover further includes:

[0019] An annular boss is provided on the water inlet side of the lower cover ring and is adapted to fit within the flared end of the water inlet of the mounting connector.

[0020] Preferably, the cover further includes:

[0021] The movable cavity is formed within the lower cover ring and the annular boss, and the end of the hose connector near the ball is located within the movable cavity.

[0022] Preferably, the cover further includes:

[0023] The first arc-shaped surface is formed on the water outlet side of the lower cover ring and is adapted to the surface of the sphere;

[0024] The second arc-shaped surface is formed on the water inlet side of the upper cover ring and is adapted to the surface of the sphere.

[0025] Preferred options also include:

[0026] The channel is formed within the hose connector, the ball, and the upper cover ring.

[0027] In the technical solution provided by this utility model, a cover is installed inside the mounting joint. This serves two purposes: firstly, it creates a good ball-and-socket fit with the ball, ensuring a tight seal between the ball and the cover and reducing friction between the ball and the mounting joint; secondly, it facilitates the smooth contact of the sealing gasket against the cover via a snap ring, ensuring a tight seal between the periphery of the cover and the inner wall of the mounting joint. Even if the mounting joint is not fully installed between itself and the pipe opening, it does not affect the seal between the mounting joint, the hose connector, and the ball. Overall, this application has a simple structure, effectively improves the sealing effect between the mounting joint, the hose connector, and the ball, and avoids water waste.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] refer to Figure 1-3A specific embodiment of this utility model provides a universal connector for bathroom hoses, including a mounting connector 1 and a hose connector 2. The mounting connector 1 is threadedly connected to the pipe opening, and the ball 8 of the hose connector 2 is installed inside the mounting connector 1. It also includes:

[0036] The cover is located inside the water inlet end of the mounting connector 1 and is engaged with the ball joint 8.

[0037] Sealing gasket 6 is located inside the mounting joint 1 and is positioned near the water outlet side of the cover.

[0038] A retaining ring is axially engaged within the mounting joint 1. A sealing gasket 6 abuts against the cover via the retaining ring, and the periphery of the cover is sealed to the inner wall of the mounting joint 1 by the sealing gasket 6.

[0039] Existing universal joints, such as Figure 4 As shown, when using the hose, the hose connector 2 is installed at the pipe opening, and the ball 8 of the hose connector 2 is installed inside the installation connector 1. The ball 8 and the water inlet side of the installation connector 1 are sealed by the ball sealing gasket 16. Then, the pipe opening and the threaded end 3 are engaged and abut against the ball sealing gasket 16 to ensure a seal. However, when the hose is not in use, the installation connector 1 usually needs to be removed. During the repeated disassembly and assembly of the installation connector 1, scale or impurities will accumulate inside over time, and the pipe opening and the installation connector 1 cannot be fully installed. That is, the ball sealing gasket 16 is not fully squeezed by the pipe opening. At this time, the seal between the ball 8 and the water inlet side cannot be effectively guaranteed. During the use of the hose, water leakage is likely to occur between the installation connector 1 and the ball 8, resulting in water waste. In this application, a cover is installed inside the mounting connector 1. This serves two purposes: firstly, it creates a good ball-and-socket fit with the ball 8, ensuring a tight seal between the ball 8 and the cover and reducing friction between the ball 8 and the mounting connector 1; secondly, it facilitates the flat contact of the sealing gasket 6 against the cover via a retaining spring, ensuring a tight seal between the periphery of the cover and the inner wall of the mounting connector 1. Even if the mounting connector 1 is not fully installed between itself and the pipe opening, it does not affect the seal between the mounting connector 1 and the hose connector 2 and the ball 8. Overall, this application has a simple structure, effectively improving the sealing effect between the mounting connector 1 and the hose connector 2 and the ball 8, thus avoiding water waste.

[0040] Further optimization of the design includes:

[0041] Ring 5;

[0042] Spring 4, several spring 4 are fixedly connected to the water outlet side of the retaining ring 5 at equal intervals around the circumference. The spring 4 is snapped into the end of the threaded section 3 inside the mounting joint 1. The retaining ring 5 abuts against the water outlet side of the sealing gasket 6 through several spring 4. The cover is inserted into the mounting joint 1 after passing through the threaded section 3.

[0043] Further optimizations to the plan include:

[0044] The groove 14 is formed on the side wall of the mounting joint 1 and is located between the threaded section 3 and the water inlet end of the mounting joint 1. The inner diameter of the groove 14 is larger than the minor diameter of the threaded section 3.

[0045] The size of the retaining ring 5 is not greater than the minor diameter of the threaded section 3. During installation, the retaining ring 5 is first pressed into the threaded section 3. During this process, the spring 4 undergoes elastic deformation until the spring 4 moves into the groove 14 and the retaining ring 5 abuts against the water inlet side of the sealing gasket 6. The spring 4 rebounds and abuts against the end of the threaded section 3, thereby achieving the purpose of abutting the sealing gasket 6. The diameter of the sealing gasket 6 is greater than the inner diameter of the groove 14. When the retaining ring abuts against the sealing gasket 6, the edge of the sealing gasket 6 is tightly fitted to the inner wall of the groove 14 under the action of elastic force. Through the water pressure on the water inlet side, the edge of the sealing gasket 6 is tightly fitted to the inner wall of the groove 14, thereby achieving the purpose of sealing between the periphery of the cover and the inner wall of the mounting joint 1 through the sealing gasket 6.

[0046] Further optimization of the design, the cover includes:

[0047] The lower cover ring 9 is adapted to fit the water inlet side of the mounting connector 1.

[0048] The upper cover ring 7 abuts against the water inlet side of the sealing gasket 6, and the ball 8 is disposed between the upper cover ring 7 and the lower cover ring 9.

[0049] A gap is provided between the upper cover ring 7 and the lower cover ring 9, so that the upper cover ring 7 is fully abutted by the retaining spring and is not affected by the lower cover ring 9. This further ensures that the ball joint of the ball 8 is set between the upper cover ring 7 and the lower cover ring 9, ensuring a tight fit between the ball 8, the upper cover ring 7 and the lower cover ring 9, while also ensuring effective rotation.

[0050] Further optimizations to the design include:

[0051] An annular boss is provided on the water inlet side of the lower cover ring 9 and is adapted to fit within the flared end 10 of the water inlet of the mounting connector 1.

[0052] The lower cover ring 9 is installed inside the flared opening 10 by the annular boss, and is limited by the flared opening 10 through the annular boss, which effectively ensures the stability of the lower cover ring 9, thereby ensuring the rotational stability of the ball 8.

[0053] Further optimizations to the design include:

[0054] The movable cavity 15 is located within the lower cover ring 9 and the annular boss, and the end of the hose connector 2 near the ball 8 is located within the movable cavity 15.

[0055] The main function of the movable cavity 15 is to ensure that the hose connector 2 has sufficient room to move when the ball 8 rotates, thereby ensuring the universal effect.

[0056] Further optimizations to the design include:

[0057] The first arc-shaped surface 12 is opened on the water outlet side of the lower cover ring 9 and is adapted to the surface of the sphere 8.

[0058] The second arc-shaped surface 13 is formed on the water inlet side of the upper cover ring 7 and is adapted to the surface of the sphere 8.

[0059] The upper cover ring 7 and the lower cover ring 9 are made of plastic. Rubber membranes are respectively provided on the first arc surface 12 and the second arc surface 13 to form rubber sealing surfaces, which are fixedly connected to the lower cover ring 9 and the upper cover ring 7 respectively. The first arc surface 12 and the second arc surface 13 are respectively attached to the spherical surface of the ball 8 through the rubber membrane to ensure a certain degree of sealing and not affect the rotation effect.

[0060] Further optimizations to the plan include:

[0061] Channel 11 is located within the hose connector 2, the ball 8, and the top cover ring 7.

[0062] Water in the pipe enters through a hose, channel 11, the center of sealing gasket 6, the center of retaining ring 5, and threaded section 3.
