[0002] During the process of pipeline connection, a pipeline connection device is usually required. The pipeline connection device can connect two pipelines or connect a pipeline and a device. Due to the different positions of the pipelines or the different positions between the pipeline and the device, some pipeline connection devices need to be designed into an elbow structure to ensure the smooth connection between the pipelines or between the pipeline and the device.
[0003] However, due to different pipeline connection situations, the position of the pipeline may be slightly different from the pre-designed position, resulting in an incorrect angle at the pipeline connection. At this time, an ordinary elbow-type pipeline connection device cannot be smoothly connected, and additional connection structures may need to be added, increasing the installation space and also increasing the risk of leakage.
[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model
[0005] The purpose of the present utility model is to provide a pipeline connection device capable of 360° rotation, which can realize the 360° rotation of the pipeline connection device, adapt to various connection working conditions, improve the installation efficiency, and ensure the connection stability of the pipeline connection device.

[0030] First Embodiment
[0031] Please refer to Figure 1 and Figure 2 , this embodiment provides a 360° rotating pipe connection device 100, which includes a connecting elbow 110 and a union sleeve 120, and the union sleeve 120 is sleeved on the surface of the connecting elbow 110.
[0032] The connecting elbow 110 includes a bending portion 111. The two ends of the bending portion 111 are respectively a straight first connection end 112 and a second connection end 113, and both the first connection end 112 and the second connection end 113 are used for connecting with pipes.
[0033] Please cooperate to participate in Figure 3, To achieve the 360° rotatable installation of the pipe connection device 100 and the limit of the union sleeve 120 on the surface of the connecting elbow 110, the outer surface of the first connection end 112 is provided with a first limit portion 1121 and a second limit portion 1122. The first limit portion 1121 is located on the side close to the bending portion 111 of the connecting elbow 110, and the second limit portion 1122 is located on the side close to the end face of the first connection end 112. The second limit portion 1122 is a limit groove, and a limit member 130 is arranged in the second limit portion 1122. The union sleeve 120 is sleeved on the outer surface of the first connection end 112 and is limited by the first limit portion 1121 and the second limit portion 1122. A third limit groove 121 is arranged at one end of the union sleeve 120 in contact with the second limit portion 1122, and the limit member 130 is accommodated in the second limit portion 1122 and the third limit groove 121 for cooperative limitation.
[0034] The first limit portion 1121 and the second limit portion 1122 on the connecting elbow 110 are used to position the union sleeve 120 and prevent the union sleeve 120 from moving arbitrarily on the surface of the connecting elbow 110.
[0035] To increase the limiting effect of the union sleeve 120 on the surface of the connecting elbow 110, the second limit portion 1122 on the connecting elbow 110 is a limit groove. At the same time, a third limit groove 121 is arranged at one end of the union sleeve 120 in contact with the second limit portion 1122. Therefore, the third limit groove 121 and the groove of the second limit portion 1122 jointly accommodate the limit member 130, making the connection between the union sleeve 120 and the connecting elbow 110 more stable. When the water pressure is too high, it is not easy to wash open and separate the union sleeve 120 and the connecting elbow 110.
[0036] In addition, since the designed first limit portion 1121 of this embodiment protrudes from the outer surface of the connecting elbow 110, the inner diameter of the connecting elbow 110 remains unchanged, which can ensure the water flux and will not reduce the water flow due to the installation of the pipe connection device 100.
[0037] Furthermore, to facilitate the installation of the pipe connection device 100 and the pipe, a thread 122 is arranged at one end of the union sleeve 120 close to the third limit groove 121. Therefore, the first connection end 112 of the connecting elbow 110 can be directly connected and fixed to the pipe through the thread 122.
[0038] A thread relief groove 123 is arranged at the end of the thread 122, and a sealing groove 124 is formed on the inner surface of the union sleeve 120 on the side far from the third limit groove 121. Sealing members 140 are accommodated in both the sealing groove 124 and the thread relief groove 123. Through the sealing members 140 in the sealing groove 124 and the thread relief groove 123, double sealing on one side of the first connection end 112 of the connecting elbow 110 for the pipe is achieved, preventing material leakage.
[0039] In this embodiment, in order to facilitate the installation and rotation of the union sleeve 120, a chamfer is provided on one side of the end face of the second limiting portion 1122 away from the first connection end 112.
[0040] In this embodiment, in order to facilitate the installation of the union sleeve 120, a chamfer is provided on the end face of the first connection end 112.
[0041] In this embodiment, the thread 122 of the union sleeve 120 is an external thread 122.
[0042] In this embodiment, a fourth limiting portion 125 is provided at one end of the union sleeve 120 away from the third limiting groove 121. The fourth limiting portion 125 protrudes from the outer surface of the union sleeve 120, and a thread relief groove 123 is provided between the thread 122 on the union sleeve 120 and the fourth limiting portion 125.
[0043] The fourth limiting portion 125 can be used to limit the seal 140 in the thread relief groove 123 and can also be used to limit the pipeline.
[0044] In this embodiment, in order to prevent the seal 140 in the thread relief groove 123 from coming out and to facilitate the installation of the seal 140 into the thread relief groove 123, a raised platform 1251 is provided on the fourth limiting portion 125. The raised platform 1251 protrudes in the direction close to the third limiting groove 121, is located at the notch end of the thread relief groove 123, and does not close the notch of the thread relief groove 123.
[0045] In this embodiment, in order to ensure that the union sleeve 120 and the connecting elbow 110 can be smoothly sleeved and can rotate relative to each other, the inner diameter of the union sleeve 120 is larger than the outer diameter of the first connection end 112, and the difference between the two is 4.7 mm.
[0046] Please refer to Figure 4 , in this embodiment, in order to facilitate the installation and fixation of the limiting ring, the limiting member 130 is a limiting ring with an opening.
[0047] A 360° rotating pipeline connection device 100 provided in this embodiment has the following installation process and working principle:
[0048] The seal 140 is respectively installed into the thread relief groove 123 and the seal groove 124 of the union sleeve 120, and then the union sleeve 120 is sleeved on the surface of the first connection end 112 of the connecting elbow 110. The first limiting portion 1121 of the connecting elbow 110 is in limiting contact with the fourth limiting portion 125 of the union sleeve 120. The second limiting portion 1122 of the connecting elbow 110 and the third limiting groove 121 of the union sleeve 120 form an installation position for accommodating the limiting member 130. The limiting member 130 is installed in the installation position formed by the second limiting portion 1122 and the third limiting groove 121 to limit the union sleeve 120 and prevent the union sleeve 120 from sliding on the connecting elbow 110. After the installation is completed, the union sleeve 120 and the connecting elbow 110 can rotate 360°, which can adapt to the pipe installation at any angle.
[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
