Patent Application
20250116114
The present application relates to the technical field of drain technology, and in particular, to an extendable drainpipe assembly.
The elastic drainpipes currently in the market are usually formed by blow molding the expandable pipe body and the adapter into an integrated whole. When there is a need to use different lengths of drainpipe, both the expandable body and the adapter need to be remanufactured, resulting in the need to design and manufacture a new mold for the expandable body and a new mold for the adapter. Furthermore, during the use of the drainpipe, the expandable pipe body, adapter, and connecting part between the adapter and the expandable pipe body of the drainpipe are all possibly to be damaged, and since the expandable pipe body is usually fixed to the adapter, when just one of the expandable pipe body, the adapter, and the connecting part between the adapter and the expandable pipe body is damaged the expandable pipe body and the adapter need to be scrapped together, which results in the use of the cost being increased significantly. Thus, the current drainpipe design is costly and not so convenient for recycling.

In this embodiment, the first connecting structure 321 is distributed along a spiral path continuously and circumferentially in the sidewall of the first pipe connector 32, the second connecting structure 201 is distributed along a spiral path continuously and circumferentially in the sidewall of the pipe body 20; it is understandable that, in some embodiments, multiple first connecting structures 321 are spaced apart from each other and distributed along a spiral path circumferentially in the sidewall of the first pipe connector 32, multiple second connecting structures 201 are spaced apart from each other and distributed along a spiral path circumferentially in the sidewall of the pipe body 20.
When the extendable drainpipe assembly 100 is in a extended and connected state, the first adapter 30 is mountably and removably installed in screwed connection to the pipe body 20. The structure of the extendable drainpipe assembly 100 is reasonable and easy to disassemble and assemble, the pipe body 20 is convenient for replacing if needed, and the first adapter 30 can be reused if needed, which effectively reduces the cost of use. Wherein the first pipe connector 32 can be screwed into the pipe body 20 via the V-shaped thread during installation to complete the assembly, and during disassembling, it just needs to be screwed out along the original path. The installation and disassembly are efficient and convenient, without the need to use glue to strengthen the fixation (which cannot be disassembled), and there is no need for an intermediate structure with threads between the first adapter 32 and the pipe body 20, to reduce the cost and simplify the structure.
In this embodiment, the first pipe connector 32 is made of hard material and cannot be expanded and compressed, so that the pipe body 20 can be firmly installed on the first pipe connector 32. The first pipe connector 32 works well for installation and support, so the pipe body 20 is not easy to loosen and disconnect from the first pipe connector 32. For easy storage, in some embodiments, the first pipe connector 32 is made of expandable material so that when the extendable drainpipe assembly 100 is in the compressed state, the two sidewalls 10 of the first connecting structure 321 of the first pipe connector 32 are folded against each other and the first pipe connector 32 can also be compressed to reduce the occupied space for easy storage, when the extendable drainpipe assembly 100 is in the extended and separated state, the two sidewalls 10 is expanded into a V-shaped thread, and the second connecting structure 201 is also expanded into a V-shaped thread, and when the extendable drainpipe assembly 100 is in the extended and connected state, the first adapter 30 is capable of being installed in screwed connection to the pipe body 20 through the V-shaped thread.
In this embodiment, the radial diameter of the first pipe connector 32 is slightly smaller than that of the pipe body 20 so that when assembling, the outer wall of the first pipe connector 32 is abutted against the inner wall of the pipe body 20. It is understandable that, in some embodiments, the radial diameter of the first pipe connector 32 is slightly larger than that of the pipe body 20 so that when assembling, the inner wall of the first pipe connector 32 is butted against the outer wall of the pipe body 20.
In this embodiment, the first adapter seat 31 is provided with at least two first grooves 33, and the first groove 33 is located on an outer wall of the first adapter seat 31 so that the first adapter seat 31 can be jammed and installed onto the drainage of a house by the first groove 33. A plurality of first grooves 33 are symmetrically arranged on the first adapter seat 31, which can ensure that the first adapter seat 31 won't fall off along the axial direction of the drainpipe after installation.
In this embodiment, the first adapter seat 31 is provided with at least one first leak-proof gasket 34, and the first leak-proof gasket 34 is arranged around the outer wall of the first adapter seat 31 so that the first adapter seat 31 will abut against an inner wall of the drainage of the house after being jammed and installed onto the drainage of the house to provide a leak-proof sealing. The first leak-proof gasket 34 is located about one end of the first adapter seat 31 away from the first pipe connector 32. In this embodiment, two first leak-proof gaskets 34 are provided so that a double sealing may be formed, providing a better leak-proof sealing effect.
In this embodiment, the first adapter seat 31 is provided with a locking adapter 35, and the locking adapter 35 is located on the outer wall of the first adapter seat 31 so that the adapter seat 31 can be locked with the drainage of the house by screws during installation, which further ensures the stability of installation and connection. In this embodiment, two locking adapters 35 are provided, symmetrically arranged on the first adapter seat 31, so that the locking force is evenly distributed and the configuration is reasonable.
In this embodiment, the first adapter seat 31 comprises a first rectangular portion 311 and an interconnected first horn portion 312 with the first rectangular portion 311, the first horn portion 312 is connected with the first pipe connector 32, and the first rectangular portion 311 can prevent the first adapter seat 31 from loosening after installation on the drainage of the house due to the rotation of the first adapter seat 31 along the circumference of the drainage. Moreover, the space of the first rectangular portion 311 is larger than that of the first horn portion 312, so that via the first rectangular portion 311 the capacity for containing water is increased to make it easier for water to flow from the drainage of the house into the first rectangular portion 311, and the first horn portion 312 provides a guide to the flow of water to make it easier for water to enter the pipe body 20. In this embodiment, the number of first groove 33 is four, two first grooves 33 as a group, and two groups of the first groove 33 are respectively located on two oppositely disposed outer walls of the first rectangular portion 311. In other embodiments, the first adapter seat 31 can also be other hollow shapes, such as circular tubular shape, pentagonal tubular shape, etc., which is not limited herein.
It is understandable that, in some embodiments, the extendable drainpipe assembly 100 further comprises a second adapter connected to another end of the pipe body 20, the second adapter and first adapter 30 have similar structures and work in similar ways.
