Description

Technical Field

[0001] This utility model relates to the field of drainage pipe connector technology, specifically a drainage pipe connector that is easy to use. Background Technology

[0002] Drainage pipe joints are components used to connect drainage pipes. Their function is to connect different drainage pipes into a complete drainage system to achieve the smooth discharge of sewage, wastewater, etc.

[0003] Traditional drainage pipe joints are mostly rigid direct connection structures. When installing drainage pipes that are not straight or at different angles, special elbows or additional connectors need to be customized, which increases the difficulty of construction and reduces the efficiency of installation. Traditional drainage pipe joints lack filtration measures. When sewage is discharged, it is usually mixed with impurities. When these impurities enter the drainage pipe, they can easily cause blockages and are difficult to clean. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easy-to-use drain pipe connector, solving the problem of inconvenient connection of drain pipes at different angles.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a user-friendly drain pipe connector, comprising a first connecting pipe and a second connecting pipe disposed between two drain pipes, a folded flexible hose connected between the first connecting pipe and the second connecting pipe, a threaded sleeve threadedly connected to the surface of the first connecting pipe by means of a threaded portion, a threaded connecting section for use with the threaded sleeve being provided on the surface of the second connecting pipe, an internally threaded connecting sleeve being fitted around the outer periphery of both the first connecting pipe and the second connecting pipe, and a threaded interface for use with the internally threaded connecting sleeve being connected to one end of each of the two drain pipes at opposite ends.

[0006] Preferably, both the opposite sides of the first connecting pipe and the second connecting pipe are connected to a mating ring, and a sealing ring is provided on the mating ring by means of an annular groove.

[0007] Preferably, both the first connecting pipe and the second connecting pipe are connected to a limiting ring that cooperates with the internal thread connecting cylinder.

[0008] Preferably, the inner wall of the first connecting pipe is connected to an annular support frame, and a filter screen frame is provided inside the annular support frame.

[0009] Preferably, an annular buffer pad that works in conjunction with the filter screen frame is installed on the inner side of the annular support frame.

[0010] Preferably, both sides of the filter frame are threadedly connected to bolts through threaded through holes, and both sides of the bottom of the annular support frame are provided with threaded through grooves that cooperate with the bolts.

[0011] This utility model provides a drain pipe connector that is easy to use. It has the following advantages:

[0012] (1) This utility model allows for free adjustment of the connection angle through the cooperation of the first connecting pipe, the second connecting pipe and the folded hose structure, which facilitates the installation of the first connecting pipe, the second connecting pipe and the drain pipe at different angles, reducing installation costs and construction difficulty. At the same time, when not in use, the first connecting pipe and the second connecting pipe can be connected and folded together using the threaded sleeve, effectively reducing the volume and facilitating storage and transportation.

[0013] (2) Through the cooperation between the filter screen frame, bolts and ring support frame structure, the ring support frame can quickly position the filter screen frame, and the bolts can fasten the filter screen frame to prevent it from falling off during use. At the same time, the ring buffer pad can buffer the impact of water flow to a certain extent and enhance the sealing and stability of the filter screen frame installation.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-4This utility model provides a technical solution: a user-friendly drain pipe connector, including a first connecting pipe 2 and a second connecting pipe 3 disposed between two drain pipes 1, a folded flexible hose 4 connected between the first connecting pipe 2 and the second connecting pipe 3, a threaded sleeve 5 threadedly connected to the surface of the first connecting pipe 2 by means of a threaded portion, a threaded connecting section 6 for use with the threaded sleeve 5 on the surface of the second connecting pipe 3, an internally threaded connecting sleeve 7 fitted on the outer periphery of both the first connecting pipe 2 and the second connecting pipe 3, and a threaded interface 8 for use with the internally threaded connecting sleeve 7 connected to one end of each of the two drain pipes 1 at opposite ends.

[0021] Furthermore, in order to improve the sealing performance of the connection between the first connecting pipe 2 and the second connecting pipe 3 and the drain pipe 1, a mating ring 9 is connected to the opposite side of the first connecting pipe 2 and the second connecting pipe 3. A sealing ring 10 is provided on the mating ring 9 by means of an annular groove. The sealing ring 10 is made of rubber.

[0022] Furthermore, in order to limit the internal threaded connecting cylinder 7 when it is not in use, the surfaces of the first connecting pipe 2 and the second connecting pipe 3 are both connected with limiting rings 11 that cooperate with the internal threaded connecting cylinder 7.

[0023] Furthermore, in order to prevent impurities from clogging the drain pipe 1, an annular support frame 12 is connected to the inner wall of the first connecting pipe 2. A filter screen frame 13 is installed inside the annular support frame 12. An annular buffer pad 14, which is used in conjunction with the filter screen frame 13, is installed on the inner side of the annular support frame 12. The annular buffer pad 14 is made of rubber and provides a certain buffer for the filter screen frame 13 when it is impacted by water flow.

[0024] To facilitate the installation and disassembly of the filter frame 13, bolts 15 are threadedly connected to both sides of the filter frame 13 through threaded through holes, and threaded through grooves 16 are provided on both sides of the bottom of the annular support frame 12 to cooperate with the bolts 15.

[0025] When not in use, the first connecting pipe 2 and the second connecting pipe 3 are folded and stored, and are fixed by screwing the threaded sleeve 5 and the threaded connecting section 6. The folded hose 4 is wrapped inside, which is convenient for storage and transportation.

[0026] When in use, first rotate the threaded sleeve 5 to disengage it from the threaded connection section 6 of the second connecting pipe 3. At this time, the folded hose 4 is exposed. If there is an angle difference between the two drain pipes 1, the folding and telescopic performance of the folded hose 4 can be used to adapt to different installation requirements, keep the internal channel unobstructed, and ensure normal drainage.

[0027] Align the mating ring 9 of the first connecting pipe 2 with the port of the upper drain pipe 1, push the internal thread connecting sleeve 7 to fit the threaded interface 8, and then rotate the internal thread connecting sleeve 7 to screw it in along the threaded interface 8. As the internal thread connecting sleeve 7 is tightened, the sealing ring 10 on the mating ring 9 is squeezed and deformed, filling the connection gap and achieving a seal between the first connecting pipe 2 and the drain pipe 1. Repeat the above steps to connect and seal the second connecting pipe 3 with the lower drain pipe 1 to complete the installation.

[0028] When the drain pipe 1 becomes clogged and the water flow is slow, the filter screen frame 13 needs to be removed for cleaning. Rotate the internal threaded connecting sleeve 7 between the first connecting pipe 2 and the drain pipe 1 in the reverse direction to disengage it from the threaded interface 8. Remove the first connecting pipe 2 from the drain pipe 1. Then, use a tool to rotate the bolt 15 to disengage it from the threaded groove 16 at the bottom of the annular support frame 12. The filter screen frame 13 can then be removed for cleaning. After cleaning, reinstall and reset it in the reverse order.
