Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage pipe technology, and in particular to a drainage pipe with high sealing performance. Background Technology
[0002] Drainage pipes are essential facilities for collecting and discharging rainwater, sewage, and agricultural irrigation fluids. They are typically made of materials such as plastic, concrete, or reinforced concrete. Key characteristics of drainage pipes include drainage safety, corrosion resistance, strength, flexibility, and economy. For example, high-density polyethylene (HDPE) is a commonly used drainage pipe material because its corrugated structure and needle-punched geotextile coating effectively prevent clogging and improve drainage efficiency.
[0003] A search revealed a novel drainage pipe with good sealing performance, published under announcement number CN217355942U. Specifically, this relates to the field of drainage pipe technology. Traditional drainage pipes mostly use annular sealing rings for connection; however, the sealing effect of annular sealing rings is poor, and because there is no fastening mechanism on adjacent drainage pipes, the connection stability between adjacent drainage pipes is poor, leading to easy leakage. The proposed pipe includes a first drainage pipe, with a second drainage pipe detachably attached to one end. The coordinated action of a T-shaped and a U-shaped annular sealing ring effectively improves the sealing performance at the connection between the first and second drainage pipes. Through the fastening mechanism, the second drainage pipe can be moved closer to the first drainage pipe via a corresponding arc-shaped plate, further improving the connection stability and sealing performance between the first and second drainage pipes, thus preventing leakage.
[0004] Based on the aforementioned patent, the traditional drainage pipes mentioned in the background technology mostly use annular sealing rings for sealing during connection. However, the sealing effect of annular sealing rings is poor, and since no fastening mechanism is set on adjacent drainage pipes, the connection stability between adjacent drainage pipes is poor, which easily leads to water leakage. In order to address this technical problem, this application proposes a drainage pipe with high sealing performance. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly sealing drainage pipe. Through the installation of gaskets, leakage between the first and second pipes can be prevented. Furthermore, the elastic force of the tension spring drives the connecting rod to move downward, causing the fixing block on the connecting rod to move downward and correspond to the limiting ring, thereby ensuring a tight connection between the first and second pipes and improving the sealing performance.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A high-sealing drainage pipe includes a first pipe, a second pipe at the right end of the first pipe, a plurality of stabilizing components on the outer wall of the first pipe to improve the stability of the connection between the first pipe and the second pipe, a support base on the outer wall of both the first pipe and the second pipe, a limit component at the top of the support base to fix the first pipe and the second pipe, and a fixing component at the bottom of the support base to prevent the first pipe and the second pipe from shifting.
[0008] Furthermore, the stabilizing component includes multiple support frames fixedly connected to the outer wall of the first pipe. Each support frame has a connecting rod rotatably connected to its inner wall. Each connecting rod has a pressing plate fixedly connected to its left end and a fixing block fixedly connected to its right end. A limit ring is fixedly connected to the outer wall of the second pipe. The left end of the fixing block corresponds to the right end of the limit ring. The inner wall of the connecting rod is connected to the outer wall of the first pipe by a tension spring.
[0009] Furthermore, one end of the tension spring is connected to the inner wall of the connecting rod, and the other end of the tension spring is connected to the outer wall of the first pipe.
[0010] Furthermore, the right end of the fixing block is set in an arc shape, and the left end of the limiting ring is set in an arc shape.
[0011] Furthermore, the limiting component includes a fixing ring located at the top of the support base, and the fixing ring is connected to the support base by a second bolt.
[0012] Furthermore, the fixing component includes a base plate fixedly connected to the bottom end of the support, and both ends of the base plate are threaded with first bolts.
[0013] Furthermore, a gasket is provided between the first pipe and the second pipe.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the gasket can prevent leakage between the first pipe and the second pipe, and the tension spring can drive the connecting rod to move downward, causing the fixing block on the connecting rod to move downward and correspond to the limiting ring, so that the first pipe and the second pipe can be tightly connected and the sealing performance can be improved.
[0016] 2. In this utility model, the base plate is fixed to the ground by the first bolt, the first pipe and the second pipe are limited to the support by the fixing ring, and the first pipe and the second pipe are fixed by the second bolt to prevent the first pipe and the second pipe from shifting.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-2 This utility model provides an embodiment of a high-sealing drainage pipe, including a first pipe 1, a second pipe 2 at the right end of the first pipe 1, multiple support frames 3 fixedly connected to the outer wall of the first pipe 1, connecting rods 4 rotatably connected to the inner wall of each support frame 3, a pressing plate 6 fixedly connected to the left end of each connecting rod 4, and a fixing block 5 fixedly connected to the right end of each connecting rod 4. A limiting ring 7 is fixedly connected to the outer wall of the second pipe 2, the left end of the fixing block 5 corresponds to the right end of the limiting ring 7, the inner wall of the connecting rod 4 is connected to the outer wall of the first pipe 1 by a tension spring 14, one end of the tension spring 14 is connected to the inner wall of the connecting rod 4, and the other end of the tension spring 14 is connected to the outer wall of the first pipe 1. The right end of the fixing block 5 is arc-shaped, and the left end of the limiting ring 7 is arc-shaped to improve the stability of the connection between the first pipe 1 and the second pipe 2. A gasket 8 is provided between the first pipe 1 and the second pipe 2.
[0024] Specifically, by inserting the second pipe 2 into the first pipe 1, the gasket 8 provides a seal. The tension spring 14 causes the connecting rod 4 to rotate inward along the support frame 3, which in turn causes the fixing block 5 to move inward, so that the fixing block 5 corresponds to the limiting ring 7, allowing the first pipe 1 and the second pipe 2 to be tightly connected, improving the seal. Furthermore, the arc shape of the fixing block 5 and the limiting ring 7 makes it easier to insert the second pipe 2. By pressing the button 6, the limiting between the fixing block 5 and the limiting ring 7 can be easily released, facilitating the disconnection of the first pipe 1 and the second pipe 2.
[0025] Reference Figure 1 and Figure 3 Both the first pipe 1 and the second pipe 2 are provided with support bases 11 on their outer walls. A fixing ring 12 is provided at the top of the support base 11. The fixing ring 12 is connected to the support base 11 by a second bolt 13 to fix the first pipe 1 and the second pipe 2. The bottom end of the support base 11 is fixedly connected to a base plate 9. Both ends of the base plate 9 are threaded with first bolts 10 to prevent the first pipe 1 and the second pipe 2 from shifting.
[0026] Specifically, the base plate 9 is fixed to the ground by the first bolt 10, and the first pipe 1 and the second pipe 2 are placed on the support base 11. The fixing ring 12 is fixed to the first pipe 1 and the second pipe 2 by the second bolt 13 to fix the first pipe 1 and the second pipe 2, so as to prevent the first pipe 1 and the second pipe 2 from shifting and to ensure the stable operation of the drainage system.
[0027] Working Principle: First, by inserting the second pipe 2 into the first pipe 1 and using the pre-set gasket 8 to achieve a sealing effect, the tension of the spring 14 drives the connecting rod 4 to rotate inward along the support frame 3, thereby pushing the fixing block 5 to move inward. This action aligns the fixing block 5 with the limiting ring 7, ensuring a tight connection between the first pipe 1 and the second pipe 2, improving the sealing performance. Furthermore, the arc-shaped design of the fixing block 5 and the limiting ring 7 makes the insertion of the second pipe 2 easier. By pressing the button plate 6, the locking between the fixing block 5 and the limiting ring 7 can be easily released, thus facilitating the separation of the first pipe 1 and the second pipe 2. Next, the base plate 9 is firmly fixed to the ground using the first bolt 10. Subsequently, the first pipe 1 and the second pipe 2 are placed on the support base 11, and the fixing ring 12 is tightened between the first pipe 1 and the second pipe 2 using the second bolt 13. This series of operations ensures the stability of the first pipe 1 and the second pipe 2, preventing their displacement and thus guaranteeing the stable operation of the drainage system.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
