Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a connection structure adapted to pipes with different diameters. Background Art

[0002] When supplying water and draining water, it is necessary to use a connecting structure to connect the water pipes together. The connecting structure that adapts to different pipe diameters is a component that connects pipes. It can connect pipes of different diameters so that the pipe system can run smoothly. The connecting structure that adapts to different pipe diameters can also reduce the resistance of the pipe system. In the pipe system, due to the different diameters of the pipes, the flow speed of the fluid in the pipe is also different. When the fluid passes through a pipe with a smaller diameter, the flow rate will increase, thereby generating greater resistance, and when the fluid passes through a pipe with a larger diameter, the flow rate will slow down, thereby generating less resistance. Using large and small joints, the pipe with a smaller diameter can be connected to the pipe with a larger diameter, thereby reducing the resistance of the pipe system and improving the flow efficiency of the fluid. The common connecting structure that adapts to different pipe diameters on the market, when connected to the connection position with the largest diameter, will move to the outside of the connection position with a smaller diameter after the water flows, which will generate a greater impact force, affecting the connection strength and sealing effect of the connecting structure. After the connecting structure is used for a long time, more dirt will be attached to the inner wall. When the dirt continues to accumulate, it will cause blockage, affecting the drainage effect. Utility Model Content

[0003] The disclosed embodiment relates to a connection structure adapted to different pipe diameters, wherein after the connection structure is connected to the pipeline and water flows rapidly, the water flow impacts a force-bearing plate assembly. Since the force-bearing plate assembly is arranged at an angle, a rotational force is generated after the force-bearing plate assembly is impacted by water, causing the rotating shaft to rotate inside the bottom assembly, causing the rotating shaft to drive the rotating plate and the scraper to rotate together, and the outer portion of the scraper contacts the inner wall of the connection structure to scrape off the residue on the inner wall of the connection structure, thereby improving the cleaning effect and avoiding continuous accumulation of dirt.

[0004] In a first aspect of the present disclosure, a connection structure adapted to different pipe diameters is provided, specifically comprising: a connection structure; a groove is provided on the outer side of the connection structure, a reducing structure is connected to the top end of the connection structure, the interior of the reducing structure is communicated with the interior of the connection structure, two sealing ring structures made of flexible rubber are fixed to the bottom end of the reducing structure, and the sealing ring structure of the annular structure is a hollow structure; a bottom component; the bottom component is installed at the bottom of the connection structure, a scraper is fixed to the top end of the bottom component through a rotating shaft and a rotating plate, the outer end of the scraper with a triangular structure is in contact with the inner wall of the connection structure, and an inclined force plate component is fixed to the inner side of each scraper, and the two force plate components are symmetrically arranged.

[0005] In at least some embodiments, the outer side of the connecting structure is welded and fixed with an outer plate structure that is evenly arranged in a ring shape, the outer side of the outer plate structure is provided with a groove, and the inside of the groove is fixed with a fixing block with a pyramidal structure; the bottom of the connecting structure is fixed with a connecting head structure, the outer side of the connecting head structure is provided with a thread, the outside of the connecting head structure is connected to the inside of the pipeline, the bottom of the connecting head structure is provided with a connecting groove, and the inner edge position of the connecting groove is provided with a thread; the top of the connecting structure is provided with a top groove, and the top groove and the bottom of the reducing structure, the bottom of the top groove are fixed with an auxiliary structure, and the outer side of the auxiliary structure is an inclined structure.

[0006] In at least some embodiments, two side plate assemblies are fixed on both sides of the bottom assembly of the annular structure, and a support rod is fixed to the outer ends of the two side plate assemblies on the same side; a fixed head assembly is fixed to the top of each support rod, and the fixed head assembly is connected to the thread inside the connecting groove, and a freely rotatable rotating shaft is inserted into the interior of the bottom assembly; a rotating plate with a long strip structure is fixed to the outside of the rotating shaft, and an inner rod assembly is fixed at the middle position of the top end of the rotating plate, the top end of the inner rod assembly is a conical structure, and the side of the inner rod assembly is connected to the force-bearing plate assembly.

[0007] The utility model provides a connection structure adapted to pipes of different diameters, which has the following beneficial effects:

[0008] When the pipeline is connected to the maximum diameter connection position, the pipeline is covered outside the bottom end of the variable diameter structure. After the pipeline is fastened by the clamp, the pipeline is compressed and contacts the sealing ring structure of rubber material. Since the sealing ring structure is made of rubber material and is a hollow structure, it can be stressed and contact with the inside of the pipeline in an anti-slip manner. At the same time, it adaptively deforms and seals to improve the sealing effect. When the water channel moves to the outside of the front end of the variable diameter structure and a large impact is generated, the pipeline can improve the connection effect with the variable diameter structure and will not be separated or loosened due to stress.

[0009] After the connecting structure is connected to the pipeline and water flows quickly, the water flow impacts the force-bearing plate assembly. Since the force-bearing plate assembly is arranged at an angle, after the force-bearing plate assembly is impacted by the water, a rotational force is generated, causing the rotating shaft to rotate inside the bottom assembly, causing the rotating shaft to drive the rotating plate and the scraper to rotate together. The outside of the scraper contacts the inner wall of the connecting structure to scrape off the residue on the inner wall of the connecting structure, thereby improving the cleaning effect and avoiding continuous accumulation of dirt.

The two force plate components 207 are symmetrically arranged, so that after water flows quickly, the water impacts the force plate component 207 and forces it to generate a rotational force, which drives the rotating shaft 204 to rotate together, and at the same time drives the scraper 206 to rotate together, so that the scraper 206 contacts the inner wall of the connecting structure 1, scrapes off the residue and dirt on the inner wall of the connecting structure 1, and improves the cleaning effect.

[0025] In the present disclosure, Figure 3 and Figure 4 As shown, the outer side of the connection structure 1 is welded and fixed with an outer plate structure 101 that is evenly arranged in a ring shape, which is located at the outer protection of the connection structure 1 to prevent external forces from affecting the connection structure 1. A groove is provided on the outer side of the outer plate structure 101, and a fixing block 102 with a pyramidal structure is fixed inside the groove, which is fixed in contact with the installation position; a connector structure 103 is fixed at the bottom of the connection structure 1 for connecting with the pipeline, and a thread is provided on the outer side of the connector structure 103. The outer side of the connector structure 103 is connected to the inside of the pipeline, and a connecting groove 104 is provided at the bottom of the connector structure 103. The inner edge position of the connecting groove 104 is provided with a thread, which is used to connect with the fixed head assembly 203, so that the bottom assembly 2 is driven to be installed and used together; a top groove 105 is provided at the top of the connection structure 1, so that after the clamp is tightened, the extruded pipeline is embedded in the inside of the top groove 105, thereby improving the sealing effect and the fixing effect, and the top groove 105 and the bottom of the reducer structure 107, the bottom of the top groove 105 is fixed with an auxiliary structure 106, and the outer side of the auxiliary structure 106 is an inclined structure.

A support rod 202 is fixed to the outer end of the two side plate assemblies 201 on the same side; a fixed head assembly 203 is fixed to the top of each support rod 202, and the fixed head assembly 203 is connected to the thread inside the connecting groove 104, driving the bottom assembly 2 to be firmly fixed for use, and a freely rotatable rotating shaft 204 is inserted into the interior of the bottom assembly 2, so that the rotating shaft 204 is in the interior of the bottom assembly 2 and can rotate freely for use; a rotating plate 205 with a long strip structure is fixed to the outside of the rotating shaft 204, and an inner rod assembly 208 is fixed at the middle position of the top of the rotating plate 205, and the top of the inner rod assembly 208 is a conical structure, and the side of the inner rod assembly 208 is connected to the force-bearing plate assembly 207, driving the force-bearing plate assembly 207 to rotate together for use.

If it is connected to the maximum caliber position, the clamp can be controlled to be connected to the outside of the top pipeline, squeeze the top pipeline, and the top pipeline The sealing ring structure 108 is squeezed by the road, causing the sealing ring structure 108 to deform, automatically improving the sealing effect, and preventing the water flow from impacting the outside of the top of the variable diameter structure 107, resulting in a greater impact strength, causing the top pipeline to separate from or leak from the connecting structure 1. While the water is flowing quickly, the water flow impacts the force-bearing plate assembly 207.
