Description

Technical Field

[0001] This application relates to the field of pipe fitting technology, and in particular to rotary joints for pipe connections. Background Technology

[0002] Currently, a connector is a device used to connect two electrical or mechanical systems, enabling them to exchange signals, power, or data. During the connection process, it is necessary to select the appropriate connector type, such as threaded connections, quick couplings, or soldered connectors.

[0003] In existing technology, when threading the ends of two pipes, two threaded connectors are first selected, and then connected to the corresponding pipes. The two connectors are then aligned and tightened clockwise to ensure a tight connection. During the connection process, sealing tape or sealant is typically used to enhance the seal and prevent leakage. After the connection is complete, it is checked for looseness or leakage to ensure the pipeline is secure and reliable.

[0004] Regarding the aforementioned technologies, the inventors believe that during the tightening process of the connector, the corresponding pipeline will also rotate, which will cause the pipeline to twist. After prolonged use, the twisted pipeline will drive the connector to rotate in the opposite direction, resulting in relative rotation between the two connectors and causing leakage in the delivery pipeline. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a rotary joint for pipe connection, which solves the technical problem that a twisted pipe will cause the joint to rotate in the opposite direction, resulting in leakage of the conveying pipe.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rotary joint for pipe connection includes: a first joint having a first connecting portion and a first rotating portion; a second joint having a second connecting portion and a second rotating portion; a connecting pipe having the first rotating portion and the second rotating portion of both the first joint and the second joint rotatably mounted on the connecting pipe; and a rotating assembly having the first joint and the second joint rotate on the connecting pipe via the rotating assembly.

[0008] Furthermore, the first connector has a first internal thread on the side near the first connecting portion, and the second connector has a second internal thread on the side near the second connecting portion.

[0009] Furthermore, the rotating assembly includes ball bearings, and both the first and second connectors have rotating grooves. The connecting pipe has a limiting groove, and several ball bearings are spaced apart between the rotating groove and the limiting groove.

[0010] Furthermore, both the first connector and the second connector are provided with studs, which are threadedly connected to the first connector and the second connector, and one end of the stud extends toward the side close to the rotating groove.

[0011] Furthermore, a support ring is provided between the first connector and the second connector in the connecting pipe, and the first connector and the second connector abut against the support ring.

[0012] Furthermore, both the first connector and the second connector are provided with a rotating rod, one end of which is connected to the corresponding first connector and second connector, and the other end extends away from the first connector and the second connector.

[0013] Furthermore, the connecting pipe has support surfaces on both sides near the first and second joints, and the support surfaces on the connecting pipe support the pipe.

[0014] In summary, this application includes at least the following beneficial technical effects of rotary joints used for pipe connections:

[0015] 1. When connecting two pipes, select two threaded connectors and connect them to the two pipes to be connected. Then, align the connectors on the two pipes with the first and second connectors respectively. After that, the first and second connectors are rotated by the rotating component. During the rotation of the first and second connectors, the two pipes are connected to the first and second connectors respectively. As the connectors are tightened, the corresponding pipes rotate together, reducing the torsion of the pipes during the connection process and preventing the connectors from rotating in the opposite direction during use, thus reducing the possibility of leakage in the conveying pipeline.

[0016] 2. The first and second joints are supported by the support rings, and the support surfaces at both ends of the connecting pipe support the pipe, so as to make the pipe stable during docking;

[0017] 3. The rotating rod, which is installed between the first connector, the second connector, and the connecting pipe by means of ball bearings, as well as on the first connector and the second connector, improves the ease of rotation of the first connector and the second connector.

Detailed Implementation

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses rotary joints for pipe connections.

[0025] Reference Figure 1 A rotary joint for pipe connection includes a first joint 1 and a second joint 2, a connecting pipe 3 is provided between the first joint 1 and the second joint 2, and a rotating component 4 is provided on the connecting pipe 3. The first joint 1 and the second joint 2 are rotatably mounted on the connecting pipe 3 through the rotating component 4.

[0026] The first connector 1 has a first connecting part 11 and a first rotating part 12 formed at its two ends respectively. The first internal thread 13 is formed on the side of the first connector 1 near the first connecting part 11. The first rotating part 12 of the first connector 1 is rotatably mounted on the rotating tube.

[0027] The second connector 2 has a second connecting part 21 and a second rotating part 22 formed at its two ends respectively. The second internal thread 23 is formed on the side of the second connector 2 near the second connecting part 21. The second rotating part 22 of the second connector 2 is rotatably mounted on the rotating tube.

[0028] In use, select two threaded connectors and connect them to one end of the two pipes respectively. Then align the two threaded connectors with the first connector 1 and the second connector 2 respectively. After the two threaded connectors are aligned with the first connector 1 and the second connector 2, rotate the first connector 1 and the second connector 2. As the first connector 1 and the second connector 2 rotate, the pipes are connected to the first connector 1 and the second connector 2.

[0029] Reference Figure 2To improve the stability of the rotation of the first connector 1 and the second connector 2 on the connecting pipe 3, the rotating assembly 4 includes ball bearings 41, with two sets of ball bearings 41 corresponding to the first connector 1 and the second connector 2. Rotation grooves 14 are provided on the side of the first connector 1 near the first rotating part 12 and on the side of the second connector 2 near the second rotating part 22. Limiting grooves 31 are provided on both sides of the connecting pipe 3. When the first connector 1 and the second connector 2 are installed on the connecting pipe 3, the rotation grooves 14 on the first connector 1 and the second connector 2 correspond to the limiting grooves 31 on the connecting pipe 3. The corresponding ball bearings 41 are rotatably installed between the rotation grooves 14 and the limiting grooves, and several ball bearings 41 are evenly spaced around the axis of the connecting pipe 3. In use, the first connector 1 and the second connector 2 are rotatably installed on the connecting pipe 3 via the ball bearings 41.

[0030] Reference Figures 2-3 Furthermore, both the first connector 1 and the second connector 2 are provided with studs 15, which are threaded onto the corresponding first connector 1 and second connector 2. The studs 15 extend into the rotation grooves 14 of the first connector 1 and the second connector 2. When the first connector 1 and the second connector 2 are installed on the connecting pipe 3, the studs 15 are tightened towards the side closer to the connecting pipe 3, so that the studs 15 abut against one of the balls 41, thereby restricting the rotation of the first connector 1 and the second connector 2 on the connecting pipe 3, thus improving the stability of the pipeline during use.

[0031] Reference Figure 2 During use, it is necessary to rotate the first connector 1 and the second connector 2. In order to further improve the convenience of rotating the first connector 1 and the second connector 2, a rotating rod 16 is provided on the first connector 1 and the second connector 2. There are two rotating rods 16 on each of the corresponding first connector 1 and the second connector 2. One end of each of the two rotating rods 16 is integrally formed with the corresponding first connector 1 and the second connector 2, and the other end extends away from the corresponding first connector 1 and the second connector 2. In use, the first connector 1 and the second connector 2 are rotated by the rotating rods 16. In addition, by extending the rotating rods 16 outward, the rotation torque of the first connector 1 and the second connector 2 is increased, so that the stability of the first connector 1 and the second connector 2 installed on the connecting pipe 3 is improved.

[0032] Furthermore, to improve the stability of the connection between the first connector 1 and the second connector 2 on the connecting pipe 3, a support ring 32 is provided between the first connector 1 and the second connector 2 on the connecting pipe 3. The support ring 32 is integrally formed with the connecting pipe 3. When the first connector 1 and the second connector 2 are installed on the connecting pipe 3, the support ring 32 supports the first connector 1 and the second connector 2, thereby improving the stability of the installation of the first connector 1 and the second connector 2 on the connecting pipe 3.

[0033] Reference Figure 3Furthermore, both ends of the support pipe have support surfaces 33. When the pipe moves toward the side closer to the connecting pipe 3 as the first joint 1 or the second joint 2 rotates, the support surface 33 of the connecting pipe 3 supports the pipes on both sides, so that the installation position of the pipes can be unified. At the same time, the pipes are directly pressed against the connecting pipe 3, which can reduce leakage between the pipes and the connecting pipe 3.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
