TECHNICAL FIELD

[0001] The utility model relates to the technical field of water trap, more particularly to a flexible water trap. BACKGROUND

[0002] The conventional building drainage pipeline system relies on manual pipeline laying, but in the process, the installation precision problems such as misalignment and deviation of the connection between the pipelines inevitably occur due to human operation. To correct these installation errors, the common practice is to forcibly bend the pipeline or use multiple pipe fittings for complex bonding to achieve the purpose of deviation compensation. However, this method not only easily damages the pipeline, but also is tedious and time-consuming in installation steps, and lacks visual aesthetics. Especially when installing the water trap, the misalignment of the pipeline is a major installation problem.

[0003] The prior art discloses a p-type water trap, which comprises a first water trap body, an inspection port nut, an inspection port sealing ring, a bend body sealing ring, and a second water trap body. The inspection port nut is arranged at the lower part of the first water trap body, the inspection port sealing ring is arranged in the inspection port nut, the bend body sealing ring is arranged at the connection, and the first water trap body and the second water trap body are connected together through a flexible socket. In this scheme, flexible connection is adopted, the pipe material is directly inserted or removed, and the socket angle of the second water trap body is adjusted by adjusting the insertion angle of the second water trap body, that is, the angle adjustment can be realized only by disassembling the two-part bend body, which is tedious in installation steps. SUMMARY

[0004] The utility model aims at overcoming the deficiency that the prior art adjusts the socket angle by disassembling the bend body, which leads to tedious installation steps, and provides a flexible water trap, which can realize omnibearing adjustment of the socket direction and is convenient to install.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of:

[0006] The utility model provides a flexible water trap, which comprises a main body and an elbow, one end of the elbow is flexibly connected with the main body, and the other end of the elbow is provided with a first socket for connecting a drainage pipe; the utility model further comprises a flexible sealing soft rubber tube, one end of the elbow is sealingly connected with one end of the main body through the flexible sealing soft rubber tube.

[0007] The flexible water trap of the utility model comprises a main body, an elbow, and a flexible sealing soft rubber tube connected between the main body and the elbow. After the elbow is connected with the main body, the first socket of the elbow can be adjusted at multiple angles in all directions through the flexible sealing soft rubber tube, and can be connected with a drainage pipe extending in different directions, thereby facilitating installation.

[0008] Furthermore, the flexible sealing rubber tube has a first connecting ring and a second connecting ring at each end. The first connecting ring is connected to one end of the elbow, and the second connecting ring is connected to one end of the main body. By connecting the first connecting ring to the elbow and the second connecting ring to the main body, a flexible connection between the elbow and the main body is achieved.

[0009] Furthermore, it also includes an internal locking nut, which has a first internal thread. One end of the elbow has a first external thread, and the outer circumference of the elbow has a boss. A first gap is left between the first external thread and the boss. The first internal thread and the first external thread are engaged and connected. The internal locking nut, in conjunction with the boss, secures the first connecting ring within the first gap. First, the first connecting ring is placed in the first gap. The first internal thread of the internal locking nut is then threadedly connected to the first external thread of the elbow. The internal locking nut is then tightened, causing the internal locking nut, in conjunction with the boss, to press and fix the first connecting ring, thus completing the connection between the elbow and the flexible sealing hose.

[0010] Furthermore, the first connecting ring is provided with a first locking block, and the inner locking nut is provided with a first barb. The first locking block engages with the first barb. While the inner locking nut and the boss clamp the first connecting ring, the first barb engages with the first locking block to prevent the first connecting ring from coming out of the first gap when adjusting the angle of the first socket, thus ensuring the connection between the first connecting ring and the elbow.

[0011] Furthermore, the top of the first connecting ring is provided with a first convex ring, which abuts against the boss. The first convex ring increases the friction of the first connecting ring of the flexible sealing rubber tube within the first gap, further preventing the first connecting ring from coming out of the first gap and improving the leak-proof effect.

[0012] Furthermore, it also includes an external locking nut, which has a second internal thread, and one end of the main body has a second external thread. A pressure ring is provided on the inner top side of the external locking nut. The second internal thread and the second external thread are connected in conjunction. The pressure ring engages with one end of the main body to engage the second connecting ring. The external locking nut is first fitted onto the outer circumference of the flexible sealing rubber tube, and the pressure ring is secured to the second connecting ring. After the first connecting ring is compressed using the connection between the internal locking nut and the elbow, the external locking nut is then connected to one end of the main body. After tightening, the second connecting ring is compressed between the pressure ring and one end of the main body, completing the connection between the main body and the flexible sealing rubber tube. The main body and the elbow are detachably connected via the internal and external locking nuts, allowing the flexible water trap of this invention to be disassembled for cleaning.

[0013] Furthermore, the second connecting ring is provided with a second locking block, and the pressure ring of the outer locking nut is provided with a second barb. The second locking block engages with the second barb. While the outer locking nut and one end of the main body press the second connecting ring together, the second barb engages with the second locking block to prevent the second connecting ring from coming off between the outer locking nut and the end of the main body when adjusting the angle of the first socket, thus ensuring the connection between the second connecting ring and the main body.

[0014] Furthermore, the bottom of the second connecting ring is provided with a second convex ring, which abuts against the end face of one end of the main body. The second convex ring increases the friction between the second connecting ring of the flexible sealing tubing and the outer locking nut and one end of the main body, further preventing the second connecting ring from coming off and improving the leak-proof effect.

[0015] Furthermore, the main body includes a second socket, a water storage section, and a connecting port connected in sequence. The second external thread is provided at the connecting port, which is funnel-shaped, and its inner diameter gradually increases from the end closer to the water storage section to the end farther away. The second socket is used to connect pipes, the connecting port is used to connect flexible sealing hoses, the water storage section is used to store water and prevent odor in the pipe fittings, and the funnel-shaped connecting port facilitates the reception of water from the elbow and prevents blockage.

[0016] Furthermore, the bottom end of the flexible sealing rubber tube extends into the interior of the connection port. Water enters the main body from the elbow through the flexible sealing rubber tube, preventing leakage between the flexible sealing rubber tube and the main body.

[0017] Furthermore, the flexible sealing hose is a PVC hose. PVC hoses are easily deformable and have good sealing properties. After the main body and elbow are connected, the angle of the first socket of the elbow can be adjusted by the deformation of the flexible sealing hose, allowing connection of drainage pipes extending from different directions, which is convenient for installation.

[0018] Furthermore, the angle adjustment range of the central axis of the first socket in the vertical plane is 0 to 60°, and the angle adjustment range in the horizontal plane is 0 to 360°.

[0019] Compared with the prior art, the flexible water trap of this utility model has the following beneficial effects:

[0020] After the elbow is connected to the main body, the first socket of the elbow can be adjusted in all directions at multiple angles, and can be connected to drainage pipes extending from different directions, making installation convenient. Attached Figure Description

After the elbow 2 is connected to the main body 1, the first socket 21 of the elbow 2 can be adjusted in all directions and at multiple angles through the flexible sealing rubber tube 3, and can be connected to drain pipes extending from different directions, which is convenient for installation.

[0035] like Figure 3 , Figure 7 As shown, the flexible sealing rubber tube 3 has a first connecting ring 31 and a second connecting ring 32 at both ends. The first connecting ring 31 is connected to one end of the elbow 2, and the second connecting ring 32 is connected to one end of the main body 1. In practice, the first connecting ring 31 is connected to the elbow 2, and the second connecting ring 32 is connected to the main body 1, thereby achieving a flexible connection between the elbow 2 and the main body 1.

[0036] like Figure 2 , Figure 3 As shown, it also includes an inner locking nut 4, which has a first internal thread 41, as... Figure 5 As shown; one end of the elbow 2 is provided with a first external thread 22, and the outer periphery of the elbow 2 is provided with a boss 23. A first gap 24 is left between the first external thread 22 and the boss 23, as shown. Figure 4As shown; the first internal thread 41 and the first external thread 22 are connected in a mating manner, and the inner locking nut 4, in conjunction with the boss 23, secures the first connecting ring 31 within the first gap 24. In practice, the first connecting ring 31 is first placed in the first gap 24, and the first internal thread 41 of the inner locking nut 4 is threadedly connected to the first external thread 22 of the elbow 2. The inner locking nut 4 is then tightened, causing the inner locking nut 4, in conjunction with the boss 23, to press and fix the first connecting ring 31, thus completing the connection between the elbow 2 and the flexible sealing hose 3.

[0037] like Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, it also includes an external locking nut 5, which has a second internal thread 51. One end of the main body 1 has a second external thread 131. A pressure ring 52 is provided on the inner side of the top of the external locking nut 5.
