[0024] Example

[0025] like Figs. 1-3 As shown, this utility model provides a quick connection device for a pipe 11 with a tee elbow 1, including a pipe 11 and a tee elbow 1 connected to the pipe 11. The connecting end of the tee elbow 1 is provided with a connector 2 and a collar 3 screwed onto the outside of the connector 2. The collar 3 is made of a corrosion-resistant, high-temperature-resistant, and high-strength material to extend the service life of the product. The inner wall of the collar 3 is provided with segmented second threads 5, and a first sealing ring 6 is provided between two segments of the second threads 5. Second sealing rings 7 are provided at both ends of the inner wall of the collar 3. The sealing rings are made of high-quality sealing material, and the improved sealing structure ensures that each joint can effectively prevent leakage.

[0026] The first sealing ring 6 is set between the two threads to ensure that the connection between the joint 2 and the pipe 11 can remain sealed, and at the same time, it can increase friction to ensure that it will not easily loosen when facing greater pressure or vibration.

[0027] The outer wall of the connector 2 is provided with a first thread 4, which is adapted to a second thread 5. The movement of the collar 3 on the connector 2 is achieved through the first thread 4 and the second thread 5. The front end of the connector 2 is provided with three segmented arc-shaped pieces 10. Rubber strips 9 are provided on the side walls of the segmented connecting ends of the three arc-shaped pieces 10 at the front end of the connector 2. When the three arc-shaped pieces 10 are in the side wall fit together, they form a pipe-like structure. When the connector 2 is connected to the pipe, the collar 3 rotates to the connection point through the thread, applying an inward pressure to the three arc-shaped pieces 10, causing the three arc-shaped pieces 10 to be squeezed together to form a pipe-like structure. At this time, because the side wall is provided with rubber strips 9, it can be ensured that the three arc-shaped pieces 10 of the connector 2 will not be squeezed and cracked due to the locking of the external collar 3, thus increasing the service life. At the same time, the rubber strips 9 can also ensure the connection effect at the position of the connector 2, increasing friction while ensuring the sealing of the internal connection.

[0028] The inner wall of the arc-shaped piece 10 at the front end of the joint 2 is provided with a third sealing ring 8, which improves the sealing performance by being provided with a sealing ring at the front end when connected with the pipeline 11, preventing leakage.

[0029] The rear end of the joint 2 is provided with a pipeline-shaped structure, which can rotate the sleeve ring 3 to the rear end of the joint 2 when the joint 2 is not connected with the pipeline 11, ensuring that it will not be lost.

[0030] Therefore, the utility model discloses a pipeline quick connecting device with a three-way elbow, which is provided with a sleeve ring screwed on the three-way joint, and the three-section arc-shaped piece structure at the front end of the joint is used to wrap the pipeline to be connected inside the joint, and the sleeve ring is used to lock the pipeline to be connected and the joint, and sealing rings are arranged on the sleeve ring and the joint to ensure the sealing performance of the joint position, prevent leakage, and increase the friction at the joint by arranging multiple sealing rings to prevent loosening.

[0031] Finally, it should be noted that: the above examples are only used to illustrate the technical scheme of the utility model and not to limit it, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: it can still modify or equivalently replace the technical scheme of the utility model, and these modifications or equivalent replacements also cannot make the modified technical scheme deviate from the spirit and scope of the technical scheme of the utility model.
