Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, and more particularly to a leak-proof pipeline. Background Art

[0002] Pipes, as the most common equipment in drainage projects, can discharge rainwater and sewage to designated areas and centrally treat them.

[0003] During the installation of existing pipelines, the pipelines are usually installed in a splicing manner. One end of the two pipelines are fitted together, and then bolts are passed through the holes on the pipelines and connected with nuts. At this time, the two pipelines cannot be separated from each other due to the influence of the bolts and nuts, thereby completing the effect of splicing the pipelines. When splicing the pipelines, in order to avoid gaps at the joint of the two pipelines, a sealing ring is usually installed between the two pipelines before splicing. The sealing ring can improve the sealing effect between the two pipelines, prevent rainwater and sewage from leaking out through the gap at the joint of the two pipelines, and improve the sealing effect of the pipeline.

[0004] However, when the pipeline discharges rainwater and sewage, the impurities in the rainwater and sewage will come into contact with the sealing ring. After the sealing ring and the impurities in the rainwater and sewage have been in contact for a long time, the sealing ring will be corroded by the impurities in the rainwater and sewage and age, thereby weakening the sealing performance of the sealing ring. As a result, the rainwater and sewage in the pipeline can penetrate the sealing ring and leak out through the gaps at the joints of the pipeline, affecting the sealing effect of the pipeline.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a leak-proof pipe, which solves the problem that after the sealing ring is in contact with impurities in rainwater and sewage for a long time, the sealing ring will be corroded and aged by the impurities in rainwater and sewage, thereby weakening the sealing performance of the sealing ring and affecting the sealing effect of the pipe.

[0007] The above technical purpose of the present utility model is achieved through the following technical solutions: a leak-proof pipe, comprising two pipe bodies and two connecting rings, wherein the two pipe bodies are provided with sliding grooves for the two connecting rings to slide, and two placement grooves are provided on one side of the two connecting rings, and sealing rings are respectively placed between the two placement grooves, the two connecting rings are connected by a positioning component, and the two pipe bodies are connected by a fixing component.

[0008] By adopting the above-mentioned structural arrangement, when installing the pipe, the two sealing rings are placed in the placement groove on one of the connecting rings, and then the one side of the two connecting rings are driven to fit each other, and at the same time, the positions of the two connecting rings are positioned by the positioning component, and the two sealing rings are driven into the placement groove on the other connecting ring. At this time, the two connecting rings are restricted by the placement groove and cannot be separated from the two connecting rings, thereby achieving the effect of fixing the two sealing rings and the connecting rings to each other. After the two sealing rings and the fixing rings are fixed to each other, the two connecting rings are placed in the sliding groove, and the two pipe bodies are spliced by the fixing component. At this time, the two fixing rings are affected by the sliding groove and cannot be separated from the two pipe bodies, thereby completing the pipe installation. The effect of the installation is that when the rainwater and sewage in the pipe flow through the joint of the two pipe bodies, the rainwater and sewage will contact one of the sealing rings, and the sealing effect of the two pipe bodies can be improved by one of the sealing rings. When one of the sealing rings is eroded by rainwater and sewage, the rainwater and sewage will penetrate one of the sealing rings and contact the other sealing ring. At this time, the other sealing ring can prevent the rainwater and sewage from leaking out, thereby improving the sealing effect of the joint of the pipe bodies. At the same time, one of the sealing rings can also isolate most of the impurities in the rainwater and sewage, reduce the contact of the other sealing ring with the impurities in the rainwater and sewage, increase the service life of the other sealing ring, and further improve the sealing effect of the pipe joint.

When the limiting rod is inserted into the positioning groove on the other connecting ring, the spring is in a natural state.

[0010] By adopting the setting of the above-mentioned positioning assembly, when the two connecting rings need to be installed with each other, one side of the two connecting rings is fitted against each other, and the two connecting rings are driven to be concentric with each other. At the same time, the limit rod is affected and moves, and enters the positioning groove on one of the connecting rings, and drives the spring to deform and compress, and then drives the other connecting ring to rotate, while driving the positioning groove to rotate. When the two connecting rings rotate until several positioning grooves are connected to each other, the spring loses its restriction and begins to recover its deformation, and drives the limit rod to insert into the positioning groove on the other connecting ring. At this time, the two connecting rings are restricted by the limit rod and cannot rotate, and always remain concentric with each other, thereby achieving the effect of positioning the two connecting rings. At the same time, through the setting of the limit rod, when the pipeline is installed, the two connecting rings are respectively placed in the slide groove.

[0012] By adopting the above-mentioned magnet setting, when the two connecting rings are fitted together, the setting of several magnets can facilitate the judgment of whether the limit rod enters the positioning groove on the other connecting ring. At the same time, it can also improve the fixing effect between the two connecting rings, make the two fixing rings fit more tightly, and improve the sealing effect of the joint of the pipeline body.

[0015] The utility model is further configured as follows: a moisture-proof pad is slidably connected between the two sealing rings.

[0016] By adopting the above-mentioned moisture-proof pad, when rainwater and sewage penetrate one of the sealing rings, the contact between the other sealing ring and rainwater and sewage can be reduced through the setting of the moisture-proof pad, thereby improving the waterproof effect between the two sealing rings and further improving the sealing performance of the joint of the two pipes.

[0017] The utility model is further configured as follows: sealing pads are sleeved on the two connecting rings.

[0018] By adopting the above-mentioned sealing gasket, the problem of rainwater and sewage penetrating outward through the gap between the two connecting rings and the chute can be avoided, the sealing between the two connecting rings and the chute is improved, and the sealing effect of the pipe joint is improved.

[0019] The utility model is further configured as follows: a filter is fixedly connected to the inner sides of the two connecting rings.

Position, and drive the two sealing rings 5 into the placement groove 4 on the other connecting ring 2. At this time, the two connecting rings 2 are restricted by the placement groove 4 and cannot be separated from the two connecting rings 2, thereby achieving the effect of fixing the two sealing rings 5 and the connecting rings 2 to each other. After the two sealing rings 5 and the fixing ring 12 are fixed to each other, the two connecting rings 2 are placed in the slide groove 3, and the two pipe bodies 1 are spliced through the fixing assembly. At this time, the two fixing rings 12 are affected by the slide groove 3 and cannot be separated from the two pipe bodies 1, thereby completing the effect of installing the pipeline.

At the same time, the limiting rod 7 is affected and moves, and enters the positioning groove 6 on one of the connecting rings 2, and drives the spring 8 to deform and compress, and then drives the other A connecting ring 2 rotates, and at the same time drives the positioning groove 6 to rotate. When the two connecting rings 2 rotate until several positioning grooves 6 are connected to each other, the spring 8 loses its restriction and begins to deform and recover, and drives the limit rod 7 to insert into the positioning groove 6 on the other connecting ring 2. At this time, the two connecting rings 2 are restricted by the limit rod 7 and cannot rotate, and always remain concentric with each other, thereby achieving the effect of positioning the two connecting rings 2. At the same time, through the setting of the limit rod 7, when the pipeline is installed, the two connecting rings 2 are respectively placed in the slide groove 3. At this time, the two pipeline bodies 1 are affected by the limit rod 7, and can also have the effect of pre-fixing the two pipeline bodies 1, which is convenient for the subsequent installation of the pipeline body 1.

At the same time, it can also improve the fixing effect between the two connecting rings 2, make the two fixing rings 12 fit more tightly, and improve the sealing effect of the joint of the pipeline body 1.

[0037] like Figure 1 、 Figure 4 、 Figure 7As shown, the fixing assembly includes two rotating frames 11 that are rotatably connected to each other, two fixing rings 12 are fixedly connected to the two pipe bodies 1, and the two fixing rings 12 are slidably connected to the inner side walls of the rotating frames 11, one of the rotating frames 11 is rotatably connected to a bolt 13, and a nut 14 is threadedly connected to the bolt 13, and a connecting plate 15 is fixedly connected to the other rotating frame 11, and a limiting groove 16 for the sliding of the bolt 13 is opened on the connecting plate 15. When installing the two pipe bodies 1, the two connecting rings 2 are placed in the slide groove 3, and then one end of the two pipe bodies 1 is driven to fit together, and at the same time, the side walls of the two fixing rings 12 are driven to fit together, and then one of the rotating frames 11 is placed on the two fixing rings 12, and driven The rotating frame 11 is sleeved on the two fixing rings 12, and then the other rotating frame 11 is driven to rotate, and the other rotating frame 11 is also driven to be sleeved on the two fixing rings 12, and then the bolt 13 is driven to rotate toward the connecting plate 15, and the bolt 13 is driven to enter the limiting groove 16, and then the nut 14 is driven to rotate and contact with the connecting plate 15.

When the two connecting rings 2 rotate to several positioning grooves 6 are connected to each other, the spring 8 loses its restriction and begins to deform and recover, and drives the limiting rod 7 to insert into the positioning groove 6 on the other connecting ring 2, and at the same time drives the two sealing rings 5 into the placement groove 4 on the other connecting ring 2. At this time, the two connecting rings 2 are restricted by the placement groove 4 and cannot be separated from the two connecting rings 2, thereby achieving the effect of fixing the two sealing rings 5 and the connecting ring 2 to each other.

At this time, the two fixing rings 12 are affected by the slide groove 3 and cannot be separated from the two pipe bodies 1, thereby completing the effect of installing the pipeline.

One of the sealing rings 5 can improve the sealing effect of the sealing point of the two pipeline bodies 1. When one of the sealing rings 5 is eroded by rainwater and sewage, the rainwater and sewage will penetrate one of the sealing rings 5 and contact the other sealing ring 5. At this time, the other sealing ring 5 can prevent the rainwater and sewage from leaking outward, thereby improving the sealing effect of the joint of the pipeline bodies 1. At the same time, one of the sealing rings 5 can also isolate most of the impurities in the rainwater and sewage, reduce the contact between the other sealing ring 5 and the impurities in the rainwater and sewage, increase the service life of the other sealing ring 5, and further improve the sealing effect of the pipeline joint.
