Technical Field

[0001] This utility model relates to the field of drainage pipeline technology, specifically a connection structure for municipal water supply and drainage pipelines. Background Technology

[0002] During operation, drainage pipes rely on multiple sets of interconnected pipes to ensure the normal flow and transport of water. However, existing drainage pipe systems rely solely on spiral connections to maintain the seal at the joints, and the suspended installation of some pipes makes it difficult to ensure the stability of the connections. Therefore, this paper proposes a new connection structure for municipal water supply and drainage pipes to address these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a connection structure for municipal water supply and drainage pipes, so as to solve the problem mentioned in the background art that the existing drainage pipes, in the process of use, only rely on spiral or other connection methods to ensure the sealing of the connection, and that some pipes are suspended and it is inconvenient to ensure the stability of the connection.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a municipal water supply and drainage pipeline connection structure, including a drainage pipe, a connecting pipe spirally attached to one end of the drainage pipe, rubber sealing rings respectively provided at both ends of the connecting pipe, and multiple sets of limiting blocks provided near the end of the rubber sealing rings and the limiting blocks respectively inserted through the connecting pipe, hollow blocks respectively provided on the outer side of the limiting blocks, and elastic limiting blocks inserted inside the hollow blocks, limiting holes correspondingly opened on the outer side of the connecting pipe, and elastic limiting blocks inserted into the limiting holes, and a first spring provided inside the hollow block, with the other end of the first spring connected to the elastic limiting block;

[0005] The connecting pipe is fitted with fixing rings at both ends, and the fixing rings are provided with telescopic rods on both outer walls. The telescopic rods are inserted into the hollow rod, and the other end of the hollow rod is provided with a connecting block. The hollow rod is provided with a second spring inside, and the other end of the second spring is connected to the telescopic rod. The drain pipe is provided with fixing blocks on the upper and lower outer walls, and bolts are inserted into the connecting blocks, with the lower end of the bolts screwed into the fixing blocks.

[0006] The fixing ring has a groove on its outer wall, and a fixing rod is inserted in the groove. The fixing rod is spirally inserted into the support rod, and the support rod has a spiral groove. The fixing rod has a corresponding thread on its outer wall.

[0007] Preferably, the rubber sealing ring forms a locking and limiting structure with the connecting pipe through the limiting block, and the limiting block, through the hollow block, the first spring, and the elastic limiting block, is inserted into the limiting hole to form an elastic locking and limiting structure with the connecting pipe.

[0008] Preferably, the connecting block forms an elastic telescopic structure with the second spring, the telescopic rod, the hollow rod, and the fixing ring, and the connecting block forms a spiral locking structure with the fixing block with bolts.

[0009] Preferably, the support rod forms a helical locking structure with the fixing rod through a helical groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The rubber sealing ring of the municipal water supply and drainage pipe connection structure forms a locking and limiting structure with the connecting pipe through the limiting block, and the limiting block, through the hollow block, the first spring, and the elastic limiting block inserted into the limiting hole, forms an elastic locking and limiting structure with the connecting pipe. Thus, the rubber sealing ring can increase the sealing performance of the connection between the connecting pipe and the drainage pipe. At the same time, the elastic limiting block assembly further increases the stability of the rubber sealing ring. The connecting block of the device forms an elastic telescopic structure with the second spring, the telescopic rod, the hollow rod, and the fixing ring. The connecting block forms a spiral locking structure with the fixing block through bolts. Thus, the second spring assembly can increase the connectivity between the two sets of drainage pipes and the connecting pipe, further increasing the sealing performance of the drainage pipe connection structure. The support rod of the device forms a spiral locking structure with the fixing rod through the spiral groove. Thus, when part of the drainage pipe is suspended, the stability of the drainage pipe connection can be increased by the spirally installed support rod. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a municipal water supply and drainage pipeline connection structure, including a drainage pipe 1, a connecting pipe 2 spirally attached to one end of the drainage pipe 1, rubber sealing rings 3 respectively provided at both ends of the connecting pipe 2, and multiple sets of limiting blocks 4 provided near one end of the rubber sealing rings 3 and the limiting blocks 4 respectively inserted through the connecting pipe 2, hollow blocks 5 respectively provided on the outer side of the limiting blocks 4, and elastic limiting blocks 6 inserted inside the hollow blocks 5, limiting holes correspondingly opened on the outer side of the connecting pipe 2, and elastic limiting blocks 6 inserted into the limiting holes, and a first spring 7 provided inside the hollow blocks 5, and the other end of the first spring 7 connected to the elastic limiting block 6.

[0019] Furthermore, the rubber sealing ring 3 forms a locking and limiting structure with the connecting pipe 2 through the limiting block 4, and the limiting block 4, through the hollow block 5, the first spring 7, and the elastic limiting block 6, is inserted into the limiting hole to form an elastic locking and limiting structure with the connecting pipe 2. Thus, the sealing effect at the connection of the drain pipe 1 can be increased by the rubber sealing ring 3, and the stability of the rubber sealing ring 3 during use can be increased by the elastic locking and limiting component.

[0020] The connecting pipe 2 is fitted with fixing rings at both ends, and the fixing rings are provided with telescopic rods 9 on both outer walls. The telescopic rods 9 are inserted into the hollow rod 8, and the other end of the hollow rod 8 is provided with a connecting block 11. The hollow rod 8 is provided with a second spring 10 inside, and the other end of the second spring 10 is connected to the telescopic rod 9. The drain pipe 1 is provided with fixing blocks 12 on the upper and lower outer walls, and bolts 13 are inserted into the connecting block 11, and the lower end of the bolts 13 is screwed into the fixing block 12.

[0021] Furthermore, the connecting block 11 forms an elastic telescopic structure with the second spring 10, the telescopic rod 9, the hollow rod 8 and the fixing ring, and the connecting block 11 forms a spiral locking structure with the fixing block 12 with the bolt 13. Thus, under the action of the second spring 10, the two sets of drain pipes 1 generate a force in the direction of the connecting pipe 2, further increasing the connectivity between the drain pipe 1 and the connecting pipe 2.

[0022] The fixing ring has a groove on its outer wall, and a fixing rod 14 is inserted in the groove. The fixing rod 14 is spirally inserted into the support rod 15. The support rod 15 has a spiral groove, and the fixing rod 14 has a corresponding thread on its outer wall.

[0023] Furthermore, the support rod 15 forms a spiral locking structure with the fixing rod 14 through a spiral groove, thereby further increasing the stability of the partially suspended drain pipe 1 through the spirally installed support rod 15.

[0024] Working principle: When using the municipal water supply and drainage pipe connection structure, one end of the drain pipe 1 can be spirally installed onto the connecting pipe 2. At the same time, rubber sealing rings 3 are placed at both ends of the connecting pipe 2 by means of elastic limiting blocks 6. This increases the sealing of the connection between the drain pipe 1 and the connecting pipe 2 through the rubber sealing rings 3. The elastic limiting blocks 6 and their related components also increase the stability of the rubber sealing rings 3 during use. After the rubber sealing rings 3 are installed, the fixing rings fitted on the connecting pipe 2 can be pushed to both ends, and under the action of the second spring 10, the connecting block 11 is aligned with the fixing block 12, so that the connecting block 11 can be secured with bolts 13. Block 12 is spirally installed, thereby causing the drain pipe 1 to generate a force towards the connecting pipe 2 under the action of the second spring 10, further ensuring the connection between the drain pipe 1 and the connecting pipe 2; if the drain pipe 1 is installed in a suspended position, a support rod 15 of appropriate length can be spirally installed on the fixed pipe 14 according to the installation position, and the support rod 15 assembly can be rotated to a suitable position through the groove on the fixed ring, so as to support the connection of the drain pipe 1 through the support rod 15, or to spirally install the support rod 15 in a suitable position through the spiral assembly to increase the overall stability of the drain pipe 1. This is the usage process of the municipal water supply and drainage pipeline connection structure.

[0025] Although the present invention 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 invention should be included within the protection scope of the present invention.
