[0002] At present, in pipeline construction, the main fixed connection methods between pipelines are threaded connection or welding. Generally, the above construction methods have a long construction period and great maintenance difficulty. Therefore, there is an urgent need for a connection structure that is fast in construction and convenient in maintenance and use.

[0003] In view of the problems in the prior art, those skilled in the art have improved it. For example, a welded ring shoulder type high-pressure mine quick connection pipe clamp with the publication number of CN214248657U includes two pipe clamps. Convex platforms are provided on both sides of the pipe clamp, and one side of the convex platform is open. Two quick clamping components are provided, and the quick clamping components are inserted into the convex platform. The quick clamping components include a clamping flap, a clamping column and a rotating shaft. The clamping flap is rotationally connected to the clamping column through the rotating shaft, and a cam structure is provided on the clamping flap: the long diameter direction of the cam structure is consistent with the direction of the clamping flap. Its advantage is to realize the quick connection and quick disassembly of the pipe clamp.

[0020] See Figures 1 to 3 , the present utility model provides a pipe connector with a welding ring structure, including a first welding ring 1 and a second welding ring 5. One end of the first welding ring 1 is fixedly connected with an arc-shaped plate 12. One end of the arc-shaped plate 12 is slidably inserted into the second welding ring 5, that is, the second welding ring 5 is slidably sleeved on the arc-shaped plate 12. One side of the first welding ring 1 and the second welding ring 5 are both fixedly connected with connection blocks 13. The connection blocks 13 are rotatably connected with a rotating shaft 14. The other side of the first welding ring 1 is fixedly connected with a first shoulder block 4. The other side of the second welding ring 5 is fixedly connected with a second shoulder block 6. In the prior art, there are various types of welding rings. The welding ring with protruding parts on both sides is a shoulder-type welding ring, so it is named shoulder block. This will not be elaborated in this specification. Both the first shoulder block 4 and the second shoulder block 6 are provided with clamping grooves 3. A clamping bar 2 is slidably connected to the outer side walls of the first welding ring 1 and the second welding ring 5. The clamping grooves 3 and the clamping bar 2 cooperate. One end of the first shoulder block 4 is fixedly connected with a plurality of connecting rods 10. The connecting rods 10 are slidably inserted into the second shoulder block 6, that is, the second shoulder block 6 is slidably sleeved on the connecting rods 10.

[0021] See Figures 1 to 3, in a further embodiment, both the first welding ring 1 and the second welding ring 5 are arranged to be openable and closable. The first welding ring 1 and the second welding ring 5 are each divided into a moving part and a fixed part. The connecting block 13 and the rotating shaft 14 on the moving part are fixedly connected, and the connecting block 13 and the rotating shaft 14 on the fixed part are rotatably connected. That is, the first welding ring 1 and the second welding ring 5 can be arranged to be openable and closable, and there is no need to fix the welding ring in advance, saving the installation time and improving the installation efficiency.

[0022] See Figures 1 to 3 , in a further embodiment, the clamping strip 2 is slidably connected to the outer side walls of the moving parts of the first welding ring 1 and the second welding ring 5. The clamping strip 2 and the clamping groove 3 will be disengaged, so the clamping strip 2 does not contact the fixed part, thus ensuring the opening and closing of the first welding ring 1 and the second welding ring 5.

[0023] See Figures 1 to 3 , in a further embodiment, the moving part and the fixed part of the first welding ring 1 are both connected with a first shoulder block 4, and the moving part and the fixed part of the second welding ring 5 are both connected with a second shoulder block 6. The first shoulder block 4 and the second shoulder block 6 also cooperate with the first welding ring 1 and the second welding ring 5 respectively, facilitating the complete clamping of the clamping strip 2 and the clamping groove 3, improving the stability of the welding ring, and further ensuring that the pipeline will not disconnect and fall off after connection.

[0024] See Figures 1 to 3 , in a further embodiment, an auxiliary plate 7 is provided on the top of the second shoulder block 6, a support plate 8 is provided on the auxiliary plate 7, a sliding shaft 9 is slidably connected to the support plate 8, a plurality of through holes 11 are arranged at equal intervals on the connecting rod 10, and the through holes 11 cooperate with the sliding shaft 9. During the process of pipeline connection, there will be gaps when connecting some fixed pipelines. The second welding ring 5 can be extended under the action of the arc-shaped plate 12 and the connecting rod 10, that is, the length of the entire welding ring can be increased. The through holes 11 and the sliding shaft 9 can fix the stretching length of the second welding ring 5. That is, when stretched to a certain distance, the sliding shaft 9 passes through the through holes 11 on the connecting rod 10, restricting the second welding ring 5 from continuing to extend or retract. The auxiliary plate 7 and the support plate 8 prevent the sliding shaft 9 from falling off, and the top of the sliding shaft 9 is not arranged to pass through the support plate 8.

[0025] In the implementation process of the present utility model: when connecting pipelines, the clamping strip 2 and the clamping groove 3 are disengaged, and the moving parts of the first welding ring 1 and the second welding ring 5 rotate under the action of the rotating shaft 14 and the connecting block 13, and then wrap around the pipeline. Then the clamping strip 2 and the clamping groove 3 cooperate to make the first welding ring 1 and the second welding ring 5 completely closed and closely fit. At the same time, when the first welding ring 1 and the second welding ring 5 rotate, the arc-shaped plate 12 will also rotate accordingly;

[0026] When connecting fixed pipes, that is, when there is a certain distance between two pipes, the clamping strip 2 and the clamping groove 3 are disengaged, and the sliding shaft 9 and the through hole 11 on the connecting rod 10 are disengaged. Pull the second welding ring 5 to make the distance between the first welding ring 1 and the second welding ring 5 greater than the distance between the pipes. The sliding shaft 9 and the through hole 11 on the connecting rod 10 are engaged to prevent the second welding ring 5 from sliding further, and then the clamping strip 2 and the clamping groove 3 are engaged to complete the connection of the pipes.

[0027] The present utility model provides a pipe connector with a welding ring structure. By setting a rotating shaft and a connecting block, the welding ring can be an integral whole before installation, solving the problem of needing to position before installation. By setting a clamping strip and a clamping groove, the rapid installation or rapid disassembly of the welding ring can be completed, improving the installation efficiency. By setting an arc-shaped plate, a connecting rod, a through hole, a sliding shaft, a first welding ring and a second welding ring, it can be applicable to different fixed pipe connections, expanding the applicable range of the welding ring structure. The structure of the present utility model is simple and convenient to use. It can make the welding ring an integral whole before installation, solve the problem of needing to position before installation, can complete the rapid installation or rapid disassembly of the welding ring, improve the installation efficiency, and can be applicable to different fixed pipe connections, expanding the applicable range of the welding ring structure.

[0028] Certainly, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
