Description

Technical Field

[0001] This utility model relates to the field of pipeline connection equipment technology, and in particular to a pressure-reducing drainage pipe connector. Background Technology

[0002] Pressure-reducing drainage pipes are engineering facilities used to reduce groundwater pressure and drain accumulated water. They are commonly found in civil engineering, building engineering, or geological engineering, and are mainly used to solve structural stability problems caused by excessive water pressure.

[0003] In existing technologies, the fixing and connection of pressure-reducing water pipes mostly adopts traditional connection devices, which directly fix the pressure-reducing water pipes to the surface of the wall by binding. At the same time, the connection between two pipes is mostly done by directly connecting flanges or butt joints. Under strong water pressure fluctuations, the above-mentioned fixing and connection methods are prone to causing the butt joints to fall off under the action of vibration, affecting the connection of the pipes and causing damage to the pipes.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0018] See Figure 1 and Figure 2This utility model provides a pressure-reducing drainage pipe connector, which includes an intermediate connecting group fastened to two pipe joints 1 to be connected. By setting the intermediate connecting group, it is ensured that the pipe joints 1 can be connected and fixed through the intermediate connecting group, ensuring the normal fixation of the pipe joints 1. An outer connecting group is sleeved outside the intermediate connecting group, which fixes the position of the intermediate connecting group, ensuring the normal fixation of the pipe joints 1. The outer connecting group includes a pressing inner core 5 that presses the intermediate connecting group and a fixed outer shell set outside the pressing inner core 5. The fixed outer shell fixes the pipe joints 1 to the wall. The pressing inner core 5 is slidably connected to the fixed outer shell, and a thrust spring 52 is provided between the pressing inner core 5 and the fixed outer shell to move the pressing inner core 5 in the direction of pressing the intermediate connecting group. In use, the pressing inner core 5 can be pressed to the intermediate connecting group by the thrust spring 52. In order to ensure the vibration buffering of the pipe joints 1 and the intermediate connecting group, a damper can be set for the thrust spring 52 to ensure the buffering effect. One side of the fixed outer shell is fixedly installed on the wall.

[0019] The wall and the fixed shell can be fixed with expansion bolts to ensure the fixing effect between the pipe joint 1 and the front, and at the same time ensure the normal installation and fixing of the fixed shell.

[0020] See Figure 1 , Figure 2 and Figure 4 Preferably, the intermediate connecting assembly includes two symmetrically arranged semicircular retaining rings 6. The outer walls of the semicircular retaining rings 6 are fixed by bolts. The retaining force of the bolts directly clamps and fixes the semicircular retaining rings 6 to the pipe joints 1. The outer wall of the end of the pipe joint 1 is provided with a positioning ring groove. The inner wall of the semicircular retaining ring 6 is provided with a positioning ring protrusion 61 that cooperates with the positioning ring groove. The two pipe joints 1 are fixed by the cooperation of the positioning ring groove and the positioning ring protrusion 61, preventing the pipe joints 1 from moving axially, thereby fixing the position of the pipe joints 1. The inner wall of the semicircular retaining ring 6 is provided with a flow guiding part 62 corresponding to the inner wall of the pipe joint 1. The end of the flow guiding part 62 fits against the end of the pipe joint 1 to prevent changes in the flow cross section of the pipe and affect the flow of the liquid.

[0021] In one embodiment of this utility model, the fixed housing includes a first semicircular housing 4 and a second semicircular housing 2. The outer side wall of the second semicircular housing 2 is close to the wall. The first semicircular housing 4 and the second semicircular housing 2 are fixed by long bolts 3, and the first semicircular housing 4 and the second semicircular housing 2 are fixed to the wall by expansion bolts, thereby completing the fixing of the first semicircular housing 4 and the second semicircular housing 2, while ensuring that the fixed housing can be fixed to the wall.

[0022] Combination Figures 1-4In one exemplary embodiment of the utility model, two clamping inner cores 5 are provided, which are slidably connected to the first semicircular outer shell 4 and the second semicircular outer shell 2 respectively. By providing two clamping inner cores 5, the outer wall of the intermediate connecting group is pressed against it, thereby ensuring the fixation of the intermediate connecting group and the vibration buffering effect. The outer walls of the first semicircular outer shell 4 and the second semicircular outer shell 2 are provided with sliding holes 22. The corresponding clamping inner core 5 includes a clamping part 53 that fits against the intermediate connecting group and a sliding column 51 provided on the outside of the clamping part 53. The sliding column 51 is slidably connected to the inside of the sliding hole 22. The thrust spring 52 cooperates with the sliding column 51 to move the clamping inner core 5 towards the direction of clamping the intermediate connecting group, ensuring that the clamping force of the intermediate connecting group can be applied. At the same time, when the pipeline vibrates, the clamping inner core 5 can buffer the vibration force.

[0023] In another exemplary embodiment of this utility model, the pressing inner core 5 is an arc-shaped gasket. The arc-shaped gasket is embedded inside the first semi-circular outer shell 4 and the second semi-circular outer shell 2. The inner wall of the arc-shaped gasket is in close contact with the outer wall of the intermediate connecting group. In order to ensure the buffering effect of the arc-shaped gasket, the arc-shaped gasket can be made of elastic materials such as rubber to buffer the vibration force of the intermediate connecting group.

[0024] Even better, in order to ensure the normal fixing and installation of the intermediate connecting group by the fixed shell, both ends of the first semicircular shell 4 and the second semicircular shell 2 are provided with limiting parts 21. The inner side of the limiting part 21 is in close contact with both ends of the intermediate connecting group. The limiting part 21 is an arc plate structure that abuts against both ends of the intermediate connecting group, thereby restricting the axial movement of the intermediate connecting group.

[0025] When using, combine Figures 1-4 When pipes need to be connected, the intermediate connection group is first fixed, and the positioning ring groove and positioning ring protrusion 61 are matched to connect the pipe joint 1. The two semi-circular retaining rings 6 are fixed with bolts. Then, the fixed outer shell is fixed to the outside of the intermediate connection group. The first semi-circular outer shell 4 is directly fixed to the wall with expansion bolts. At this time, the pressing inner core 5 is compressed by the pressure and the thrust spring 52 is fixed to the intermediate connection group. When the pressure inside the pipe fluctuates and vibration occurs, the pressing inner core 5 buffers the vibration force, thereby completing the protection of the pipe joint 1 and the intermediate connection group.

[0026] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
