Technical Field
[0001] This utility model relates to the field of drain pipe connection technology, and in particular to a drain pipe connection structure with strong adaptability. Background Technology
[0002] A sewer system is a piping system used to discharge wastewater and sewage. It is responsible for directing wastewater generated in homes, industries, businesses, and cities from houses or buildings to sewage treatment plants or systems for treatment and disposal. The sewer system guides wastewater into the sewer system by connecting to indoor drainage facilities (such as kitchen sinks, bathrooms, toilets, etc.), and then further discharges it into sewage treatment facilities. This effectively removes wastewater from indoors, maintaining environmental cleanliness and hygiene.
[0003] Currently, kitchen sink drainers are used in household kitchens, as shown in the attached image. Figure 4 This can be used in conjunction with a drain spout to filter food scraps and prevent clogging of the sewer; while sink drains are commonly used in bathrooms and other areas, such as... Figure 5 The drain pipe, when used with a switch at the bottom of the sink, allows water to be stored in the sink for easy use. However, the connection ports at the bottom of sink drain pipes and vegetable sink drain pipes are usually different, and due to different manufacturers, they may be threaded or unthreaded. The thread direction and thread pitch of threaded drain pipes also vary, often resulting in mismatches when users purchase drain pipes for the bottom of the drain pipe. Later, flexible rubber tips were introduced to install drain pipes with hose clamps. However, hose clamps have disadvantages such as short lifespan and easy leakage. Therefore, there is an urgent need to design and produce a highly adaptable drain pipe connection structure to meet the needs of actual use. Utility Model Content
[0004] This utility model provides a highly adaptable drain pipe connection structure, which solves the technical problems in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides a highly adaptable drain pipe connection structure, including a drain bend and a plug. A connecting and fixing component is fixedly installed on the top of the drain bend. The connecting and fixing component includes a large end connection part and a small end connection part, which are connected to each other. The surface of the small end connection part is integrally formed with threads. A compression cap is connected to the top of the connecting and fixing component through the threads. A soft rubber head is adhered to the surface of the small end connection part, and the compression cap is fitted onto the surface of the soft rubber head.
[0006] Preferably, the wall thickness of the soft tip gradually decreases from top to bottom, the soft tip is soft in texture, and the inner wall of the soft tip fits into the surface of the small end connection.
[0007] Preferably, the inner wall of the clamping cap has a toothed groove that matches the thread, and the wall thickness of the clamping cap gradually increases from top to bottom.
[0008] Compared with related technologies, the drain pipe connection structure with strong adaptability provided by this utility model has the following beneficial effects:
[0009] This utility model provides a highly adaptable drain pipe connection structure. The threaded design allows the clamping cap to be adjusted in position on the connecting and fixing components. The soft rubber head is fitted inside the clamping cap, and the clamping cap can be rotated to press the soft rubber head tightly, thereby ensuring a tight connection between the soft rubber head and the lower end of the drain assembly. The higher the clamping cap is positioned, the stronger the fastening effect between the soft rubber head and the drain assembly. It is also compatible with the lower end of drain assemblies of a certain diameter range. Furthermore, it can be used with drain assemblies that are either threaded or not, demonstrating strong adaptability. Attached Figure Description

[0019] Implementation examples, by Figure 1-5The present invention includes a drain bend 4 and a pipe 5. A connecting and fixing component 1 is fixedly installed on the top of the drain bend 4. The connecting and fixing component 1 includes a large end connecting part 11 and a small end connecting part 12. The large end connecting part 11 and the small end connecting part 12 are connected to each other. The surface of the small end connecting part 12 is integrally formed with threads 13. A compression cap 2 is threadedly connected to the top of the connecting and fixing component 1 through the threads 13. A soft leather head 3 is bonded to the outer surface of the connecting part 12. The compression cap 2 is sleeved on the surface of the soft leather head 3.
[0020] In this embodiment, the large end connector 11 is used to connect the drain bend 4. The small end connector 12 of the connecting and fixing component 1 is fitted inside the soft head 3. By continuously twisting the clamping cap 2, the clamping cap 2 moves upward, and the clamping cap 2 can press the soft head 3 tightly onto the lower surface of the sink drain 100 or washbasin drain 200, thereby making the soft head 3 tightly connected to the lower end of the drain. This not only replaces the hose clamp currently used, but also has a long service life and a wide range of compatible soft head 3 diameters. It can also be used on various shapes of threads, making it highly adaptable.
[0021] The wall thickness of the soft tip 3 gradually decreases from top to bottom. The soft tip 3 is soft in texture, and the inner wall of the soft tip 3 fits against the surface of the small end connector 12.
[0022] In this embodiment, the soft rubber head 3 can be slightly deformed or stretched to fit over the surface of the small end connecting part 12. The thicker upper end and thinner lower end of the soft rubber head 3 can increase the tightening effect of the clamping cap 2 on the soft rubber head 3, making it easier to tighten the lower end of the drainer.
[0023] The inner wall of the clamping cap 2 has a toothed groove that matches the thread 13, and the wall thickness of the clamping cap 2 gradually increases from top to bottom.
[0024] In this embodiment, the inner wall of the clamping cap 2 is inclined, which can accommodate more sizes and increase the tightening effect of the clamping cap 2 on the soft leather head 3, making it easier to tighten the lower end of the drainer.
[0025] Working principle: The thread 13 allows the clamping cap 2 to be adjusted on the connecting and fixing part 1. The soft head 3 is fitted inside the clamping cap 2. By rotating the clamping cap 2, the soft head 3 can be clamped, thus making the soft head 3 tightly connected to the lower end of the drain. The higher the position of the clamping cap 2, the stronger the fastening effect between the soft head 3 and the drain. It is compatible with the lower end of drains of a certain diameter. In addition, it can be used with drains with or without threads at the lower end, making it highly adaptable.
