[0002] Wall pipes, also known as waterproof casings, refer to pipes that pass through hot water pipes, air ducts, and power lines inside buildings or walls. They are mainly used in plumbing projects to bring hot water pipes or cold water pipes from outdoors to indoors, solving water inlet and outlet problems and making residents' lives more convenient and efficient. Waterproof casings are mainly divided into rigid waterproof casings and flexible waterproof casings. Their application scenarios are different: flexible waterproof casings are mainly used in areas with high waterproofing requirements, such as civil defense walls and reservoirs; while rigid waterproof casings are mostly used in places where pipes should pass through, such as villa basements.

When they need to be installed on walls of different thicknesses, different types of wall-through pipes are usually required, or the wall-through pipes are cut and installed. Moreover, the wall-through pipes in the prior art can usually only be connected to one type of pipe, which affects the adaptability. Therefore, an assembled wall-through pipe is designed to solve the above problems. Utility Model Content
