Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spliced grooved pipe fittings, and more specifically, it relates to a spliced grooved pipe fitting. Background Art
[0002] In the existing pipe connection technology, spliced grooved pipe fittings are a common solution, which aims to simplify the operation process of pipe connection and disconnection. However, in the prior art, the operation of pipe fitting connection is usually rather cumbersome, which is mainly manifested in the need to use a large number of tools and accessories, as well as complex assembly steps. Such cumbersome operation not only prolongs the installation time, but also easily leads to installation errors, thus affecting the stability and safety of the pipe system.
[0003] Although there are some devices in the prior art that can achieve quick connection or disassembly between pipes, these structures often have design defects. For example, these quick connection devices may result in poor sealing effect at the pipe connection, because they often rely on simple clamping or buckling mechanisms, and these mechanisms may not provide sufficient sealing pressure. Poor sealing effect will cause leakage in the pipe system, which not only causes waste of resources, but also may lead to safety accidents or environmental pollution.
[0004] In addition, in the prior art, when it is necessary to remove the corresponding pipe, it is usually impossible to quickly seal the corresponding joint, which means that during the removal process, the fluid or gas in the pipe may leak out, causing potential safety hazards and environmental pollution. At the same time, when connecting the pipe, due to the lack of an effective internal connection mechanism, it is usually necessary to separately open the switch to ensure the smoothness inside the pipe. This process is not only cumbersome to operate, but also prone to mistakes. Especially in a large-scale pipe system, the complexity of this operation may lead to serious consequences.

When the second spring 15 is squeezed to the limit, one end of the insertion rod 19 is flush with the inner wall of the fixed tube 12. Then insert the corresponding end of the insertion tube 7 into the fixed tube 12. Then release the mating sleeve 10. The second spring 15 will push the return block 13 to reset. Then the return block 13 will drive the mating sleeve 10 to reset. Then the mating sleeve 10 will drive the mating frame 11 and the insertion rod 19 to reset through the variable diameter frame 8 and the variable diameter slot 9. Then the insertion rod 19 will stably insert into the insertion slot 20, thus realizing stable and rapid connection between the pipelines.
[0035] Please refer to Figures 1-5 , as an implementation manner of the leak-proof device: The leak-proof device includes a gasket 21, a through groove 22 and a sliding sleeve 23. The gasket 21 is detachably installed inside the fixed tube 12. The through groove 22 is opened on the side wall of the fixed tube 12. The sliding sleeve 23 is movably arranged outside the fixed tube 12.

[0038] A plurality of sealing rings 27 and sealing grooves 26 are provided.
[0039] More specifically, before the pipes need to be docked, first push the sliding sleeve 23 in the corresponding direction. Then, the sliding sleeve 23 and the fixed plate 24 cooperate to squeeze the first spring 25. After the insertion rod 19 is inserted into the insertion groove 20, release the sliding sleeve 23. The first spring 25 will push the sliding sleeve 23 to reset. Then, the sliding sleeve 23 will push the insertion rod 19 and the fitting frame 11 to move, so that the insertion rod 19 slides along the through groove 22. Then, the insertion rod 19 will drive the insertion pipe 7 through the insertion groove 20 to press the gasket 21 provided on one side, ensuring the sealing effect at the pipe connection. At the same time, a plurality of sealing rings 27 provided on the outer side of the insertion pipe 7 will be respectively engaged into the corresponding sealing grooves 26, thereby further enhancing the sealing performance at the pipe connection and effectively preventing leakage at the pipe connection.
[0040] In summary, when the overall device is in use or operation: when the insertion tube 7 is completely inserted into the fixed tube 12, it means that the external pipeline is completely docked with the four-way pipe 1. At the same time, the insertion tube 7 will push open the sliding bracket 16, so that the sliding bracket 16 and the corresponding connecting plate 2 cooperate to squeeze the second push spring 18 sleeved outside the connecting rod 17. At the same time, the sliding bracket 16 will drive the tapered block 6 to move through the connecting rod 17. Then the tapered block 6 will push the sealing block 3 to spread outwards, causing a gap between the sealing blocks 3. At the same time, the sealing block 3 will squeeze the first spring 25 arranged on one side. Then, water flow or air can smoothly pass through the slot opened on the sliding bracket 16, the water passing slot 4 opened on the connecting bracket, and the gaps existing between the multiple sealing blocks 3 and enter the inside of the four-way pipe 1 and flow into the corresponding pipelines. When the corresponding insertion tube 7 is removed, the sliding bracket 16 loses its limit, the second push spring 18 resets and pushes the sliding bracket 16 to reset. Then the sliding bracket 16 will drive the tapered block 6 to reset. At the same time, the multiple first springs 25 will respectively push the corresponding sealing blocks 3 to re-abut against the outside of the tapered block 6, so that there is no longer a gap between the sealing blocks 3, thereby preventing pipeline leakage when the insertion tube 7 is removed. When it is necessary to dock the pipelines, first rotate the mating sleeve 10 in the corresponding direction. The mating sleeve 10 will drive the return block 13 arranged on one side to move. Then the return block 13 and the fixed block 14 cooperate to squeeze the second spring 15. At the same time, the mating sleeve 10 will drive the variable diameter bracket 8 arranged on the outside to move. The variable diameter bracket 8 will drive the mating bracket 11 to move relatively outwards through the variable diameter slot 9 opened inside. Then the mating bracket 11 will drive the insertion rod 19 to move outwards. When the second spring 15 is squeezed to the limit, one end of the insertion rod 19 is flush with the inner wall of the fixed tube 12. Then insert the corresponding end of the insertion tube 7 into the fixed tube 12. Then release the mating sleeve 10. The second spring 15 will push the return block 13 to reset. Then the return block 13 will drive the mating sleeve 10 to reset. Then the mating sleeve 10 will drive the mating bracket 11 and the insertion rod 19 to reset through the variable diameter bracket 8 and the variable diameter slot 9. Then the insertion rod 19 will be stably inserted into the insertion slot 20, thus realizing stable and rapid connection between the pipelines.
[0041] Before the pipeline needs to be connected, first push the sliding sleeve 23 in the corresponding direction. Then, the sliding sleeve 23 and the fixed plate 24 cooperate to squeeze the first spring 25. After the insertion rod 19 is inserted into the insertion slot 20, release the sliding sleeve 23. The first spring 25 will push the sliding sleeve 23 to reset. Then, the sliding sleeve 23 will push the insertion rod 19 and the fitting frame 11 to move, so that the insertion rod 19 slides along the through slot 22. Then, the insertion rod 19 will drive the insertion pipe 7 through the insertion slot 20 to press the gasket 21 arranged on one side, ensuring the sealing effect of the pipeline connection. At the same time, a plurality of sealing rings 27 arranged on the outer side of the insertion pipe 7 will be successively engaged into the corresponding sealing grooves 26, thereby further strengthening the sealing performance of the pipeline connection and effectively preventing leakage at the pipeline connection.
