Description

Technical Field

[0001] This utility model relates to the field of pipe fittings and joints, and in particular to a union elbow joint. Background Technology

[0002] When installing bathroom fixtures, angle fittings are often used for connection. In existing technology, angle fittings usually have fixed connecting threads on both ends. Since the distance and angle between each pipe and bathroom fixture are difficult to be consistent during decoration, the installation distance and angle need to be adjusted according to the site dimensions to ensure a smooth installation and connection.

[0003] When using a fixed thread structure for connection, the spacing and angle between the connecting threads can only be adjusted by rotating the bend joint or connector. However, if the connecting threads are adjusted too tightly, it can easily damage the pipes or bathroom equipment; if the connecting threads are adjusted too loosely, it can easily leak water. A new connecting joint needs to be developed to address this problem. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a flexible elbow joint that can be rotated and adjusted, has good sealing performance when rotated, is easy to match and install with bathroom equipment, and is convenient to install and use.

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

[0006] A flexible elbow joint includes an elbow body and a connecting nut. One end of the elbow body is provided with connecting threads, and the other end of the elbow body is provided with a connecting hole. A positioning protrusion is provided in the connecting hole. A sealing rotating sleeve is movably connected to the positioning protrusion. A sealing ring is provided between the sealing rotating sleeve and the connecting hole. A limiting flange is provided at the outer end of the sealing rotating sleeve. The connecting nut is connected to the sealing rotating sleeve through the limiting flange.

[0007] Furthermore, the inner end of the sealing rotating sleeve is provided with two or more elastic hooks, which can rotatably hook onto the inner edge of the positioning protrusion ring.

[0008] Furthermore, the sealing rotating sleeve is provided with a sealing groove for installing the sealing ring.

[0009] Furthermore, the connecting nut is provided with a positioning ring platform that mates with the limiting flange.

[0010] Furthermore, the sealing rotating sleeve is provided with a water passage hole.

[0011] Furthermore, the sealing rotating sleeve is made of plastic material.

[0012] Furthermore, the connecting nut is equipped with a sealing gasket that is sealed to the limiting flange.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model provides a sealing rotating sleeve between the elbow body and the connecting nut. The sealing rotating sleeve can rotate within the elbow body in a sealed manner, which facilitates the adjustment of the installation spacing and angle by rotating the sealing rotating sleeve. The sealing performance is guaranteed during rotation adjustment, which is convenient for installing and connecting bathroom equipment. It is easy to install and use.

[0015] 2. The inner end of the sealing rotating sleeve of this utility model is rotatably connected to the elbow body through an elastic hook. A sealing ring is set between the sealing rotating sleeve and the inner hole of the elbow body to ensure sealing performance. The outer end of the sealing rotating sleeve is then connected with a connecting nut. The combination structure of the elastic hook and the connecting nut facilitates installation and use.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0023] See Figure 1-4As shown, a flexible elbow joint includes an elbow body 1 and a connecting nut 2. One end of the elbow body 1 is provided with a connecting thread 11, and the other end of the elbow body 1 is provided with a connecting hole 12. A positioning protrusion 13 is provided in the connecting hole 12. A sealing rotating sleeve 3 is movably connected to the positioning protrusion 13. The inner end of the sealing rotating sleeve 3 is provided with two or more elastic hooks 32. In this embodiment, six elastic hooks 32 are provided. The hooks of the elastic hooks 32 can rotatably hook the inner edge of the positioning protrusion 13, so that the sealing rotating sleeve can rotate. The sleeve 3 is rotatable relative to the elbow body 1. A sealing ring 4 is provided between the sealing rotating sleeve 3 and the connecting hole 12. The sealing rotating sleeve 3 is provided with a sealing groove 33 for installing the sealing ring 4. The sealing ring 4 is used to realize the rotational sealing connection between the elbow body 1 and the sealing rotating sleeve 3. The outer end of the sealing rotating sleeve 3 is provided with a limiting flange 31. The connecting nut 2 is connected to the sealing rotating sleeve 3 through the limiting flange 31. The connecting nut 2 is provided with a positioning ring platform 21 that cooperates with the limiting flange 31.

[0024] The sealing rotating sleeve 3 is provided with a water passage hole 34. The sealing rotating sleeve 3 is made of plastic material, and the elastic hook 32 has a certain elasticity and can extend from the end of the connecting hole 12 to hook the inner edge of the positioning protrusion ring 13.

[0025] The connecting nut 2 has a sealing gasket 5 inside, which is sealed to the limiting flange 31 to ensure a reliable sealing connection after the joint is installed.
