Description

Technical Field

[0001] The utility model relates to the technical field of sewage discharge from public toilets, and more specifically to a municipal public toilet sewage pipe for urban and rural planning. Background Art

[0002] In the sewage system of public toilets, sewage pipes are one of the essential structures of the system.

[0003] After searching, a municipal public toilet toilet-type sewage pipe for urban and rural planning disclosed by publication number CN211257218U includes an inlet pipe, a non-return mechanism and an outlet pipe. The inlet pipe, the non-return mechanism and the outlet pipe are connected in series in sequence from top to bottom through flanges according to the direction of water inlet to form a sewage pipe structure of the entire public toilet. The non-return mechanism includes a cylinder body which is connected in series with the water outlet of the inlet pipe and the water inlet of the outlet pipe through flanges respectively. The inner side wall of the top of the cylinder body is fixedly connected with the two ends of the cross beam slats by welding. The bottom end surfaces of the cross beam slats are respectively connected with a first section baffle and a second section baffle by hinged manner. A vertical plate is fixedly welded on the bottom end surface of the cross beam slats and located between the first section baffle and the second section baffle. The bottom two sides of the vertical plate are fixedly connected with carrier plates. The first section baffle and the second section baffle are respectively fixedly installed with automatic opening and closing components between the two carrier plates.

[0004] The above-mentioned technical scheme has certain beneficial effects, but in actual use, since the installation direction of the automatic opening and closing component is oblique, and the opening method of the baffle is also oblique, forming a triangle, when in use, a large force is required to open it, and the crossbeam slats are easy to block the waste, making it easy for paper to be spread on the surface of the baffle, making it difficult to flush out the waste, and also making it impossible for the baffle to be completely reset. For this reason, we propose a municipal public toilet toilet-type sewage pipe for urban and rural planning. Utility Model Content

DETAILED DESCRIPTION

[0022] Reference Figure 1-5 The utility model provides a municipal toilet drainage type sewage pipe for urban and rural planning, comprising a first connecting pipe 1 and a second connecting pipe 2, the ends of the first connecting pipe 1 and the second connecting pipe 2 are fixedly connected with a self-opening and closing mechanism 3 by bolts;

[0023] The first and second protection mechanisms 4 and 5 are movably sleeved on the outer sides of the surfaces of the first connecting tube 1 and the second connecting tube 2 respectively.

[0024] Among them, the self-opening and closing mechanism 3 includes a mounting sleeve 6, the inner side of which is fixedly connected to a fixed mounting plate 7, and the interior of the fixed mounting plate 7 is movably connected to a self-opening and closing component 8, so that when flushing, the self-opening and closing component 8 will be impacted. The fixed mounting plate 7 can lift the self-opening and closing component 8, and the self-opening and closing component 8 can be reset after the flushing is completed, which is easy to operate.

[0025] Among them, the self-opening and closing component 8 includes a connecting guide mounting rod 10, the top of the connecting guide mounting rod 10 is fixedly connected with a movable protective sleeve block 9, the bottom end of the movable protective sleeve block 9 and the top of the fixed mounting plate 7 are fixedly connected with a reset spring 11, the top of the movable protective sleeve block 9 is fixedly connected with a connecting chassis 12, the top of the connecting chassis 12 is fixedly connected with a connecting top block 13, a fixed sealing ring 14 is provided between the outer surface of the connecting top block 13 and the top edge of the connecting chassis 12, and the inner side of the bottom end of the movable protective sleeve block 9 and the outer surface of the fixed mounting plate 7 are fixedly connected. The sides fit each other, so that when flushing, the connection top block 13 can be impacted, so that the connection bottom plate 12, the fixed sealing ring 14, the movable protective sleeve block 9 and the connection guide mounting rod 10 move downward, squeezing the reset spring 11, and the waste can move along the top inclined surface of the connection top block 13 and be discharged quickly. After the flushing is completed, the reset spring 11 can push the movable protective sleeve block 9, so that the movable protective sleeve block 9, the connection bottom plate 12, the connection top block 13 and the fixed sealing ring 14 are reset, thereby sealing.

[0026] Among them, a fixed through hole 15 is opened inside the fixed mounting plate 7, and the outer surface of the connecting guide mounting rod 10 and the inner side of the fixed through hole 15 slide and fit with each other, so that the connecting guide mounting rod 10 can stably move on the inner side of the fixed through hole 15, so that the reset spring 11 can be compressed and contracted between the movable protective cover block 9 and the fixed mounting plate 7.

[0027] Among them, the first protective mechanism 4 and the second protective mechanism 5 both include a movable protective sleeve 16, a connecting sealing ring 18 is provided on the inner side of one end of the movable protective sleeve 16, and a magnetic sealing ring 17 is provided on the other end of the movable protective sleeve 16, so that the movable protective sleeve 16 can be sleeved on the outer side of the surface of the first connecting pipe 1 and the second connecting pipe 2, and sealing can be performed through the magnetic sealing ring 17 and the connecting sealing ring 18.

[0028] Among them, adjacent magnetic sealing rings 17 fit together, and the connecting sealing ring 18 fits together with the outer surfaces of the first connecting tube 1 and the second connecting tube 2, so that the magnetic sealing rings 17 are attracted to each other and thus sealed. The connecting sealing ring 18 can stably seal the movable protective sleeve 16 and the first connecting tube 1 and the second connecting tube 2, and the operation is convenient.

[0029] The working principle of the utility model: during use, when flushing, the connection top block 13 is impacted, so that the connection bottom plate 12, the fixed sealing ring 14, the movable protective sleeve block 9 and the connection guide mounting rod 10 move downward, and the reset spring 11 is squeezed, and the waste can move along the top inclined surface of the connection top block 13 and be discharged quickly. After the flushing is completed, the reset spring 11 can push the movable protective sleeve block 9, so that the movable protective sleeve block 9, the connection bottom plate 12, the connection top block 13 and the fixed sealing ring 14 are reset, thereby sealing. Since the top of the connection top block 13 has an inclined surface, the waste can be moved quickly to prevent incomplete discharge from causing The self-opening and closing mechanism 8 is stuck, and the mutual cooperation between the movable protective sleeve block 9 and the fixed mounting plate 7 can prevent the self-opening and closing component 8 from being deflected as a whole; after the connection and installation between the first connecting pipe 1, the second connecting pipe 2 and the self-opening and closing mechanism 3 are completed, the first protective mechanism 4 and the second protective mechanism 5 are respectively moved on the outer sides of the surfaces of the first connecting pipe 1 and the second connecting pipe 2, so that the magnetic sealing rings 17 are attracted to each other for sealing, and the connecting sealing ring 18 contacts the first connecting pipe 1 and the second connecting pipe 2 for sealing, thereby preventing the connecting bolts between the first connecting pipe 1, the second connecting pipe 2 and the self-opening and closing mechanism 3 from rusting, which makes it difficult to disassemble during maintenance, and the operation is convenient.
