[0002] Pipelines are an important concept in engineering and computer science, and their definition depends on the specific application. Broadly speaking, a pipeline refers to a channel or system used to transport matter, energy, or information. Pipeline sealing joints, as an indispensable component of fluid transport systems, refer to various devices used to connect pipelines and ensure the sealing performance of the joints. Their core function is to prevent fluid leakage and maintain the integrity and safety of the pipeline system.

[0003] In existing pipe connection processes, most pipes are connected by welding or bolting. However, these connection methods usually require a long installation time, making it impossible to achieve a quick connection. This makes pipe connection work cumbersome and reduces the efficiency of pipe connection. To address this, we propose a quick-connect sealing joint for pipes. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-5 As shown, in this embodiment, a quick-connect sealing joint for pipes includes a sealing joint body 1. Connecting pipes 17 are fixedly connected to both sides of the sealing joint body 1. Sealing rings 18 are fixedly connected to the outer sides of the two connecting pipes 17 and located on both sides of the sealing joint body 1. Pipe bodies 2 are provided on the outer sides of the two connecting pipes 17. Flanges 20 are provided at one end of each of the two pipe bodies 2. One side of each flange 20 abuts against the two sealing rings 18. Arc-shaped clamping blocks 3 are slidably connected to both sides of the sealing joint body 1. A clamping assembly is provided at the top of the sealing joint body 1, which drives the two arc-shaped clamping blocks 3 to move. One side of each arc-shaped clamping block 3 abuts against the two flanges 20. A locking structure is provided at the bottom of the sealing joint body 1, which fixes the two flanges 20. Two positioning pins 10 are fixedly connected to both sides of the sealing joint body 1. Positioning holes 21 are opened on one side of each of the two flanges 20. The four positioning pins 10 contact the inner sides of the four positioning holes 21 respectively.

[0024] When quickly connecting pipes, the sealing joint body 1 is first placed between the two pipe bodies 2, so that the two connecting pipes 17 are inserted into the two pipe bodies 2 respectively. Then, the two arc-shaped clamps 3 are positioned on the outside of the two pipe bodies 2 respectively. Next, the two flanges 20 are positioned by the cooperation between the four positioning pins 10 and the four positioning holes 21. Then, the clamping assembly drives the two arc-shaped clamps 3 to move on both sides of the sealing joint body 1 respectively, and finally clamps and fixes the two flanges 20, and makes the two flanges 20 abut against the two sealing rings 18 (specifically made of rubber material to ensure sealing and durability). Finally, the two flanges 20 are further locked and fixed by the locking structure.

[0025] When the pipeline is disassembled, the locking structure releases the lock on the two flanges 20, and then the clamping assembly moves the two arc-shaped clamps 3. Next, the two flanges 20 are released from their fixation, and finally the two pipe bodies 2 are pulled out and the sealing joint body 1 is removed, thus completing the pipeline disassembly and improving the efficiency of pipeline connection.

[0026] like Figures 1-5 As shown, the clamping assembly includes two racks 4, both of which are slidably connected to the top of the sealing joint body 1. One end of each rack 4 is fixedly connected to two arc-shaped clamping blocks 3. Two limiting grooves 15 are provided on the top of the sealing joint body 1. Limiting rods 16 are fixedly connected between the inner walls of the two limiting grooves 15. Limiting blocks 19 are slidably connected to the outer sides of the two limiting rods 16. The tops of the two limiting blocks 19 are fixedly connected to the two racks 4. A rotating shaft 8 is rotatably connected to the top of the sealing joint body 1. A gear 7 is fixedly connected to the outer side of the rotating shaft 8. The gear 7 meshes with the two racks 4. A rotating wheel 9 is fixedly connected to the top of the rotating shaft 8.

[0027] By rotating the wheel 9, the shaft 8 is driven to rotate the gear 7. Then, under the meshing action of the gear 7 and the two racks 4, the two racks 4 drive the two limiting blocks 19 to move in the two limiting grooves 15 respectively. At the same time, the two limiting rods 16 limit the two limiting blocks 19. Finally, the two arc-shaped clamps 3 are driven to move on both sides of the sealing joint body 1, thereby improving the performance of the sealing joint.

[0028] like Figures 1-5 As shown, the locking structure includes a U-shaped plate 5, which is fixedly connected to the bottom of the sealing joint body 1. A connecting plate 11 is slidably connected between the inner walls of the U-shaped plate 5. Both ends of the connecting plate 11 are fixedly connected to a locking block 12. One side of each locking block 12 abuts against two flanges 20. A connecting rod 13 is fixedly connected to the bottom of the connecting plate 11. The bottom end of the connecting rod 13 extends to the bottom of the U-shaped plate 5 and is fixedly connected to a pull rod 6. A return spring 14 is provided between the inner side of the connecting plate 11 and the U-shaped plate 5. The return spring 14 is located on the outer side of the connecting rod 13.

[0029] The connecting rod 13 is moved by the pull rod 6, which in turn moves the connecting plate 11 between the inner walls of the U-shaped plate 5, thereby pressing the return spring 14 (which is made of high carbon steel), and finally moving the two locking blocks 12 away from the two flanges 20 respectively, thereby releasing the fixation of the two flanges 20.

[0030] When the two flanges 20 are fixed, the elastic action of the return spring 14 pushes the connecting plate 11 to move between the inner walls of the U-shaped plate 5, thereby driving the two locking blocks 12 to lock the two flanges 20, thus completing the fixing of the two flanges 20 and improving the stability of the pipeline connection.

[0031] This utility model provides a quick-connect sealing joint for pipelines. The specific working principle is as follows: When quickly connecting pipelines, the sealing joint body 1 is first placed between two pipe bodies 2, so that two connecting pipes 17 are inserted into the interiors of the two pipe bodies 2 respectively. Then, two arc-shaped clamps 3 are positioned on the outer sides of the two pipe bodies 2 respectively. Next, the two flanges 20 are positioned by the engagement of four positioning pins 10 and four positioning holes 21. Subsequently, by rotating the rotating wheel 9, the rotating shaft 8 drives the gear 7 to rotate. Then, under the meshing action of the gear 7 and two racks 4, the connection is completed. Two racks 4 drive two limiting blocks 19 to move in two limiting grooves 15 respectively. At the same time, two limiting rods 16 limit the two limiting blocks 19. Finally, the two arc-shaped clamping blocks 3 move on both sides of the sealing joint body 1 respectively, thereby clamping and fixing the two flanges 20 and making the two flanges 20 abut against the two sealing rings 18 respectively. Finally, through the elastic action of the return spring 14, the connecting plate 11 is pushed to move between the inner walls of the U-shaped plate 5, thereby driving the two locking blocks 12 to lock the two flanges 20, thus completing the further locking and fixing of the two flanges 20.

[0032] When the pipeline is disassembled, the connecting rod 13 is moved by the pull rod 6, which in turn moves the connecting plate 11 between the inner walls of the U-shaped plate 5, thereby pressing the return spring 14. Finally, the two clamping blocks 12 are moved away from the two flanges 20 respectively, thus releasing the fixation of the two flanges 20. Then, by rotating the rotating wheel 9, the rotating shaft 8 drives the gear 7 to rotate. Then, under the meshing action of the gear 7 and the two racks 4, the two racks 4 drive the two limiting blocks 19 to move in the two limiting grooves 15 respectively. At the same time, the two limiting rods 16 limit the two limiting blocks 19. Finally, the two arc-shaped clamping blocks 3 are driven to move on both sides of the sealing joint body 1, and the two flanges 20 are released. Finally, the two pipe bodies 2 are pulled out and the sealing joint body 1 is removed, thus completing the pipeline disassembly and completing the work of quickly connecting the sealing joint to the pipeline.
