Description

Technical Field

[0001] This utility model relates to the field of sewage pipe connection, specifically a sewage pipe connection device. Background Technology

[0002] The main function of sewage pipes is to collect, treat, and discharge sewage and waste from urban domestic wastewater, maintain public and environmental sanitation, and protect the health and safety of the people. Sewage pipes centrally treat sewage, avoiding health problems caused by direct sewage discharge, and protecting soil and groundwater from pollution. When connecting the ends of sewage pipes, multiple sets of sewage pipes need to be connected by a sealing device to extend the length of the sewage pipes.

[0003] Existing sewage pipe connection devices, such as the sewage pipe connection structure proposed in patent application number "CN202420886490.9", include two sewage pipes with a connecting pipe placed between them. This sewage pipe connection structure uses a threaded connection between a first threaded groove and a second threaded groove to conveniently fix the sewage pipes and the connecting pipe, making it easy for workers to assemble and disassemble. The placement groove is sealed by the action of a rubber ring, improving the sealing performance of the connection. At the same time, the fixing ring is fixed by the gap fit between the fixing rod and the fixing hole.

[0004] However, the existing technology has defects. The connection between the connecting pipe and the sewage pipe adopts the method of plug-in and snap-fit. When the sewage pipe or connecting pipe is damaged and needs to be replaced, multiple sets of sewage pipes or connecting pipes connected to it need to be moved or disassembled before the damaged sewage pipe or connecting pipe can be removed. The disassembly process is complicated and labor-intensive. Therefore, a sewage pipe connection device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a sewage pipe connection device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A sewage pipe connection device includes a connector, wherein pipe fittings are snapped into the interior of both ends of the connector, the connector is ring-shaped, and connecting plates are fixed to both ends of the connector. The two sets of connecting plates are fixed together by bolts, and a support assembly is snapped into the sidewalls of the two sets of pipe fittings. The connector is located inside the support assembly, and multiple sets of elastic rings are fixed to the inner wall of the connector. The multiple sets of elastic rings are arranged in a circumferential array.

[0008] Preferably, a cavity is formed between the elastic ring and the inner wall of the connector, and an installation groove is formed on the side wall of the connector. The installation groove communicates with the cavity, and a sealing plate is snapped into the installation groove. The side wall of the sealing plate is sealed and fitted with the inner wall of the installation groove, and multiple sets of filter holes are formed on the side wall of the sealing plate.

[0009] Preferably, the support assembly includes two sets of retaining rings, which are respectively snapped onto the side walls of two sets of pipe fittings. Each set of retaining rings has a notch on one side. The mounting plate is located between the two sets of notches. Multiple sets of fixing posts are fixed between the two sets of retaining rings. The multiple sets of fixing posts are arranged in a circumferential array. The connector is located between the multiple sets of fixing posts.

[0010] Preferably, both sets of pipe fittings have grooves on their sidewalls, and a sealing gasket for increasing the sealing between the pipe fitting and the connector is snapped into the groove. The sealing gasket is pressed between the connector and the pipe fitting.

[0011] Preferably, both ends of the inner wall of the connector are fixedly connected with a fixing ring, and both sets of pipe fittings have a slot on their side wall. The slot is annular in shape, and the fixing ring is engaged with the slot. The fixing ring is located on the side of the sealing gasket away from the elastic ring.

[0012] Preferably, the outer wall of the elastic ring is coated with a corrosion-resistant coating.

[0013] The beneficial effects of this utility model are:

[0014] This utility model connects two adjacent sets of pipe fittings using a connector. The connector is malleable and surrounds the ends of the two sets of connectors. After being surrounded, the connector is snapped into the pipe fitting, preventing the pipe fitting from detaching from the end of the connector. After being tightly surrounded, the two ends of the connector are fixed by bolts, making the connector and the end of the pipe fitting tightly connected. The disassembly process is simple. When sewage flows through the inside of the pipe fitting, the sewage impacts the elastic ring. The elastic ring is deformed and tilted due to the impact, preventing the sewage from impacting the connection of the pipe fitting and affecting the connection seal. The support component prevents the pipe fitting and connector from bending and being damaged. Attached Figure Description

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] A sewage pipe connection device, such as Figure 1-Figure 4 As shown, it includes a connector 2, with pipe fittings 1 snapped into the interior of both ends of the connector 2. The connector 2 is ring-shaped, and connecting plates 3 are fixed to both ends of the connector 2. The two sets of connecting plates 3 are fixed together by bolts 4. A support assembly is snapped into the sidewalls of the two sets of pipe fittings 1. The connector 2 is located inside the support assembly. Multiple sets of elastic rings 12 are fixed to the inner wall of the connector 2. The multiple sets of elastic rings 12 are arranged in a circumferential array.

[0024] Connector 2 connects two adjacent sets of pipe fittings 1, making the ends of the two sets of pipe fittings 1 connected. Connector 2 is malleable and is initially rectangular. After one end of connector 2 is positioned, the other end surrounds the connection end of the two sets of pipe fittings 1, enclosing the ends of the two sets of connector 2. After enclosing, connector 2 is snapped into pipe fitting 1 to prevent pipe fitting 1 from detaching from the end of connector 2. After tight enclosing, the two ends of connector 2 are fixed by bolts 4, so that connector 2 is tightly connected to the end of pipe fitting 1. When sewage flows through the inside of pipe fitting 1, the sewage impacts the elastic ring 12. The elastic ring 12 is deformed and tilted by the impact, preventing sewage from impacting the connection of pipe fitting 1 and affecting the connection seal. The support component prevents the pipe fitting 1 and connector 2 from bending and being damaged.

[0025] When disassembling connector 2 or pipe fitting 1, remove bolt 4 (there are not many bolts 4, so the workload is small), so that the two sets of connecting plates 3 are opened, and there is space between the support assembly and connector 2. Pull one end of the connecting plate 3 to pull out connector 2, and the two sets of pipe fittings 1 are disconnected. Slide the support assembly to remove one set of pipe fittings 1. Disassembling pipe fitting 1 or connector 2 does not require moving or disassembling multiple sets of connected pipe fittings 1 or connector 2 around it. The disassembly process is simple and reduces labor.

[0026] like Figure 1-Figure 4 As shown, a cavity 14 is provided between the elastic ring 12 and the inner wall of the connector 2. An installation groove 9 is provided on the side wall of the connector 2. The installation groove 9 communicates with the cavity 14. A sealing plate 10 is snapped into the installation groove 9. The side wall of the sealing plate 10 is sealed and fitted with the inner wall of the installation groove 9. Multiple sets of filter holes 11 are provided on the side wall of the sealing plate 10.

[0027] The cavity 14 facilitates the deformation and tilting of the elastic ring 12. When the elastic ring 12 is tilted by the impact of sewage, the space inside the cavity 14 becomes smaller, causing the air inside the cavity 14 to be discharged through the filter hole 11, blowing the air outside the connector 2, driving air flow, increasing the dryness of the environment around the connector 2, preventing corrosion of the connector 2 caused by long-term humidity, and avoiding reducing the service life of the connector 2.

[0028] like Figure 1 As shown, the support assembly includes two sets of retaining rings 15, which are respectively snapped onto the side walls of two sets of pipe fittings 1. Each set of retaining rings 15 has a notch 17 on one side. The mounting plate is located between the two sets of notches 17. Multiple sets of fixing posts 16 are fixed between the two sets of retaining rings 15. The multiple sets of fixing posts 16 are arranged in a circumferential array. The connector 2 is located between the multiple sets of fixing posts 16.

[0029] When installing the support assembly, insert a set of retaining rings 15 onto one set of pipe fittings 1, and then slide the other set of retaining rings 15 onto the same pipe fitting 1. After connecting the other set of pipe fittings 1 that need to be connected, slide the support assembly so that the two sets of retaining rings 15 are located on the two sets of pipe fittings 1. The two sets of retaining rings 15 are connected by multiple sets of fixing posts 16 to support the connection of the two sets of sewage pipes and prevent bending damage between the pipe fittings 1 and the connectors 2. The notch 17 provides sufficient installation space to facilitate the fastening of the connecting plate 3.

[0030] like Figure 2-Figure 3 As shown, both sets of pipe fittings 1 have grooves 8 on their side walls. A sealing gasket 5 for increasing the sealing between the pipe fitting 1 and the connector 2 is installed inside the groove 8. The sealing gasket 5 is pressed between the connector 2 and the pipe fitting 1.

[0031] The sealing gasket 5 increases the sealing between the pipe fitting 1 and the connector 2. The sealing gasket 5 is installed before the connector 2 is installed.

[0032] like Figure 2-Figure 3 As shown, both ends of the inner wall of the connector 2 are fixed with fixing rings 6, and both sets of pipe fittings 1 have slots 7 on their side walls. The slots 7 are annular in shape. The fixing rings 6 are snapped into the slots 7. The fixing rings 6 are located on the side of the sealing gasket 5 away from the elastic ring 12.

[0033] When the connector 2 tightly surrounds the connection between the two sets of pipe fittings 1, the fixing ring 6 is inserted into the groove 7 on the side wall of the pipe fitting 1 to prevent the pipe fitting 1 from separating from the connector 2.

[0034] like Figures 3-4 As shown, the outer wall of the elastic ring 12 is coated with a corrosion-resistant coating 13.

[0035] The corrosion-resistant coating 13 increases the corrosion resistance of the elastic ring 12 and improves its service life.

[0036] The working principle of the sewage pipe connection device provided by this utility model is as follows:

[0037] Connector 2 connects two adjacent sets of pipe fittings 1, making the ends of the two sets of pipe fittings 1 connected. Connector 2 is malleable and is initially rectangular. After one end of connector 2 is positioned, the other end surrounds the connection end of the two sets of pipe fittings 1, enclosing the ends of the two sets of connector 2. After enclosing, connector 2 is snapped into pipe fitting 1 to prevent pipe fitting 1 from detaching from the end of connector 2. After tight enclosing, the two ends of connector 2 are fixed by bolts 4, so that connector 2 is tightly connected to the end of pipe fitting 1. When sewage flows through the inside of pipe fitting 1, the sewage impacts the elastic ring 12. The elastic ring 12 is deformed and tilted by the impact, preventing sewage from impacting the connection of pipe fitting 1 and affecting the connection seal. The support component prevents the pipe fitting 1 and connector 2 from bending and being damaged.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
