Description

Technical Field

[0001] The utility model belongs to the technical field of inspection openings, and particularly relates to an inspection opening construction structure for indoor drainage pipes which is convenient for inspection. Background Art

[0002] The drainage system is a vital component of house construction, and its normal operation is essential to the comfort and hygiene of the living environment. During decoration, reserving a maintenance position for the inspection port of the drainage riser is a vital task. The inspection port is an accessory with an openable inspection cover, which is installed on the drainage riser for the purpose of inspection and clearing. It is a key part of the drainage riser. During the interior decoration process, the drainage riser is enclosed in the wall by paving tiles for the sake of aesthetics. Later, when the pipe bulges, the wall needs to be broken to use the inspection port for maintenance work; in order to solve the above technical drawbacks, the solution adopted in the prior art is to reserve a niche at the position of the wall corresponding to the inspection port, and set an openable cabinet door at the niche. When the inspection port is used, the cabinet door is opened for operation.

[0003] For example, a Chinese utility model patent with application number: CN202221181005.5 discloses a magnetic opening and closing wall inspection opening, including an outer frame and a door panel, the door panel is arranged in the inner cavity of the outer frame, and magnetic suction components are respectively arranged on the left and right inner walls of the outer frame, and the left and right ends of the inner wall of the door panel are respectively fixed by suction with the magnetic suction components; flanges adjacent to each other in sequence are respectively arranged at the periphery of the outer wall of the door panel, and fixing blocks are respectively arranged on the inner walls of the left and right flanges, and first grooves are respectively arranged at the opposite ends of the two fixing blocks, and the first grooves are both "L"-shaped and the openings are back to back, and pads are respectively arranged at the four corners of the outer wall of the door panel, and a panel is arranged in the inner cavity surrounded by the four flanges, and avoidance grooves are respectively arranged at the left and right ends of the panel corresponding to the positions of the fixing blocks, and magnet blocks are respectively arranged at the four corners of the inner wall of the panel corresponding to the positions of the pads, and the magnet blocks are fixed by suction with the pads. The above inspection opening is intended to solve the technical problems of existing inspection openings that are difficult to disassemble and assemble, and inconvenient to open and close.

[0004] However, the inspection opening is opened sideways, which not only takes up space, but also requires a hinge gap for the side-opening cabinet door, so it is not easy to set a cabinet door sealing structure, especially in the kitchen and bathroom, which may easily cause domestic water to seep into the wall niche.

As an inspection structure for the drainage pipe 1, a niche 4 is opened on the wall 2 at a position corresponding to the inspection port 3, so that the inspection port 3 can be operated without being hindered by the wall 2. For the purpose of wall beauty and anti-leakage and sealing, the opening of the niche 4 needs to be closed, so a cabinet door assembly is arranged at the opening of the niche 4, and the cabinet door assembly further includes: a frame 5, the frame 5 is fixedly connected to the opening of the niche 4, and the middle part of the frame 5 is through-set and slidably connected A cover plate 6 is connected. When in use, the cover plate 6 can be opened to operate the inspection port 3. When idle, the cover plate 6 is closed to block the inspection port 3 to make the wall more beautiful. The shape of the cover plate 6 is the same as the middle shape of the frame 5. A sealing rubber ring 8 is arranged between the cover plate 6 and the frame 5. A positioning component 7 is arranged inside the niche 4. The positioning component 7 includes: a movable rod 701 and a positioning block 702. The positioning block 702 is fixedly connected to the inner wall of the niche 4. One end of the movable rod 701 is fixedly connected to the cover plate 6, and the other end passes through the positioning block 702 and the end is fixedly connected to the limit pin 703. A compression spring 704 is sleeved on the movable rod 701, and the compression spring 704 is located between the limit pin 703 and the positioning block 702. The cover plate 6 is provided with a magnetic suction block or a suction cup or a handle.

[0024] like Figure 2-3 As shown, the positioning block 702 further includes: a positioning plate 7021, the positioning plate 7021 is fixedly connected to the inner side wall of the niche 4, a sliding seat end 7023 perpendicular to the positioning plate 7021 is provided on the side of the positioning plate 7021 away from the cover plate 6, a sliding hole 7025 is opened on the sliding seat end 7023, the sliding hole 7025 is used for sliding connection with the movable rod 701, and the compression spring 704 is located between the sliding seat end 7023 and the limit pin 703.
