Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drainage pipes, and particularly relates to a sealing connector for drainage pipes. Background Art
[0002] A drainage pipe is a kind of pipe used for transmitting and discharging water sources. Since the length of a single drainage pipe is limited, connections are generally achieved through connectors, and the primary requirement for connectors is the sealing effect.
[0003] Existing sealing connectors do not have any structure for achieving sealing by themselves. In the connection with pipes, they mainly rely on external sealing rings or sealing tapes to achieve sealing. This method is not only more cumbersome in operation, but also directly affects the sealing performance of the later connection once the installation is deviated. Therefore, there are significant limitations in actual use and there is room for improvement. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a sealing connector for drainage pipes to solve the problem of insufficient sealing of existing connectors without a sealing structure as mentioned in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A sealing connector for drainage pipes includes a pipe body; it also includes a sealing assembly composed of a sealing member and a plugging member. The sealing member is arranged near the two ends of the pipe body and abuts against the outer wall of the external drainage pipe, and can be installed through the sealing member during the connection with the external drainage pipe; the plugging member is arranged at the middle position of the pipe body and plugs the end of the external drainage pipe, thereby achieving a double-sealing effect and avoiding the phenomenon of water seepage caused by insufficient sealing of the drainage pipe in the later stage.
[0006] Preferably, the sealing member includes a rubber ring. One end of the rubber ring is bonded to the inner wall of the pipe body, and the other end bends towards the midpoint of the pipe body. The sealing member also includes a rubber gasket arranged inside the bent part of the rubber ring. When the external drainage pipe is inserted into the pipe body, the rubber ring and the rubber gasket will be squeezed. At this time, the rubber gasket rebounds, pressing the rubber ring tightly against the outer wall of the external drainage pipe, thereby achieving the sealing of the connection.
[0007] Preferably, the plugging member includes a partition ring integrally arranged at the middle position inside the pipe body. The partition ring is in an inverted "T" shape, and annular grooves for inserting the external drainage pipe are formed between the upper and lower ends of the partition ring and the inner wall of the pipe body. When the end of the drainage pipe is inserted into the annular groove, the end of the drainage pipe can be plugged, and combined with the setting of the sealing member, a double-sealing effect is achieved.
[0008] Preferably, sealing rings are also adhered to the inner sides of the two annular grooves formed by the separation ring and the pipe body. The sealing rings are in a "U" shape and wrap around the inner and outer walls of the end of the drainage pipe to further achieve a sealing effect.
[0009] Preferably, annular grooves are provided at both outer ends of the pipe body, and steel wires are sleeved inside the annular grooves. During use, the steel wires can be tightened to force the two ends of the pipe body to deform and press tightly against the drainage pipe, thereby completing the installation.
[0010] Preferably, the diameter of the steel wire is less than or equal to the inner diameter of the annular groove, and both ends of the steel wire extend towards the outside of the annular groove.
[0011] Preferably, one end of the rubber ring is adhered to the inner wall of the pipe body by means of heat melting.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] Through the designed sealing assembly, the sealing operation can be directly completed when connecting the pipes, without the need to additionally add a sealing structure. The sealing can be completed in a single connection, which is very convenient to operate and there is no problem of incomplete sealing, thus improving the deficiencies existing in the use of the existing structure.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a drainage pipe sealing connector, including
[0023] a pipe body 100;
[0024] It further includes
[0025] a sealing assembly, which is composed of a sealing member and a plugging member, wherein
[0026] the sealing member is arranged at positions adjacent to the two openings at both ends of the pipe body 100 and abuts against the outer wall of the external drainage pipe. During the connection with the external drainage pipe, installation can be achieved through the sealing member; the plugging member is arranged at the middle position of the pipe body 100 and plugs the end of the external drainage pipe, thereby achieving a double-sealing effect and avoiding the phenomenon of water seepage caused by insufficient sealing of the drainage pipe in the later stage.
[0027] In this embodiment, preferably, the sealing member includes a rubber ring 101. One end of the rubber ring 101 is adhered to the inner wall of the pipe body 100, and the other end bends towards the midpoint position of the pipe body 100. The sealing member further includes a rubber gasket 104 arranged inside the bent part of the rubber ring 101. When the external drainage pipe is inserted into the pipe body 100, the rubber ring 101 and the rubber gasket 104 will be squeezed. At this time, the rubber gasket 104 rebounds, pressing the rubber ring 101 tightly against the outer wall of the external drainage pipe, thereby achieving the sealing of the connection.
[0028] In this embodiment, preferably, the plugging member includes a partition ring 102 integrally arranged at the middle position inside the pipe body 100. The partition ring 102 is in an inverted "T" shape, and annular grooves for inserting the external drainage pipe are formed between the upper and lower ends of the partition ring 102 and the inner wall of the pipe body 100. When the end of the drainage pipe is inserted into the annular groove, the end of the drainage pipe can be plugged, and combined with the setting of the sealing member, a double-sealing effect is achieved.
[0029] In this embodiment, preferably, sealing gaskets 103 are also adhered to the inner sides of the two annular grooves formed by the partition ring 102 and the pipe body 100. The sealing gaskets 103 are in a "U" shape and wrap around the inner and outer walls of the end of the drainage pipe, further achieving the sealing effect.
[0030] In this embodiment, preferably, annular grooves 100a are formed at both outer ends of the pipe body 100. A steel wire 200 is sleeved inside the annular grooves 100a. During use, the steel wire 200 can be tightened to force the two ends of the pipe body 100 to deform and press tightly against the drainage pipe, thereby completing the installation.
[0031] In this embodiment, preferably, the diameter of the steel wire 200 is less than or equal to the inner diameter of the annular groove 100a, and both ends of the steel wire 200 extend towards the outside of the annular groove 100a.
[0032] In this embodiment, preferably, one end of the rubber ring 101 is adhesively bonded to the inner wall of the pipe body 100 by means of hot melting.
[0033] Although the embodiments of the present invention have been shown and described (see the above detailed description), those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
