Description

Technical Field

[0001] This utility model relates to the field of building drainage technology, and in particular to a corner elbow for building drainage. Background Technology

[0002] Drainage elbows are commonly used components in drainage system pipe connections. They are typically used to connect to straight pipes to achieve pipe bends. The existing connection method between drainage elbows and straight pipes is mainly socket-type, where the straight pipe is inserted into one end of the drainage elbow for connection, either threaded or with a direct interference fit.

[0003] When using the above-mentioned technologies, the following technical problems were found in the existing technologies: First, most existing technologies use bolts to connect the drainage elbows to straight pipes. However, over time, the bolts are prone to aging and rust, making bolt disassembly extremely difficult. This hinders the replacement and maintenance of the drainage elbows, significantly increasing maintenance and time costs. Second, due to the complex composition of sewage in building drainage pipes, which often contains a large amount of impurities, drainage elbows are prone to blockage. Existing technologies typically use sealing caps to seal the discharge outlets. When the sealing cap is opened to discharge the blockage, sewage and debris inside the drainage elbow will rush out together, causing inconvenience to workers and potentially contaminating their clothing with sewage spray, affecting the working environment and workers' health. Moreover, this sewage discharge method is inefficient and cannot meet actual usage needs. Therefore, we designed a corner elbow for building drainage to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a corner elbow for building drainage to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A corner elbow for building drainage includes a drainage elbow with straight pipes fitted at both ends. A connecting mechanism is provided between the drainage elbow and the straight pipes. The connecting mechanism includes a sealing gasket, a B-limiting ring, a threaded sleeve, and a reinforcing component. A threaded groove is provided on the outer side of the straight pipe near the drainage elbow. Both ends of the outer side of the drainage elbow are fixed with B-limiting rings. A threaded sleeve is rotatably connected to the outer side of the B-limiting rings. The inner side of the threaded sleeve, away from the drainage elbow, is threadedly connected to the threaded groove.

[0007] The reinforcement assembly includes an A-limiting ring, a connecting ring, a handwheel, a pressure pad, and a linkage rod. The A-limiting ring is fixed to the outside of the straight pipe. The connecting ring is rotatably connected to the outside of the straight pipe and above the A-limiting ring. Both sides of the outside of the threaded sleeve are rotatably connected to the linkage rod. The end of the linkage rod away from the threaded sleeve is rotatably connected to the handwheel.

[0008] The linkage rod is slidably connected to a pressure pad on its outer side, the bottom end of the pressure pad is slidably connected to the top of the connecting ring, and the bottom end of the handwheel is rotatably connected to the pressure pad.

[0009] The connection point between the linkage rod and the handwheel is located off-center from the center of the handwheel.

[0010] A sealing gasket is installed between the drainage elbow and the straight pipe.

[0011] The outer side of the drainage elbow is fitted with a reinforcing sleeve.

[0012] The drain elbow and the bottom of the reinforced pipe sleeve are fixed with a drain pipe. The bottom of the drain pipe is rotatably connected with a drain cover. The top of the drain cover is fixed with a garbage storage cylinder. The outside of the garbage storage cylinder is slidably connected to the drain pipe.

[0013] The drain cover has a filter pipe fixed at the top of its inner side and inside the garbage storage cylinder. The bottom end of the filter pipe passes through the drain cover and is fixed with a drain head. A valve is fitted on the outside of the drain head.

[0014] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model assembles a drainage elbow between two straight pipes, and then rotates the threaded sleeve to drive the drainage elbow and the straight pipes to form a threaded connection. This causes the threaded sleeve to compress the drainage elbow and the straight pipes, and a sealing gasket is set between the drainage elbow and the straight pipes, thereby improving the sealing effect between the drainage elbow and the straight pipes. In order to increase the sealing stability between the drainage elbow and the straight pipes, the handwheel drives the linkage rod and the threaded sleeve to rotate, while the linkage rod slides with the connecting ring. At this time, rotating the handwheel uses its protruding part to compress the pressure gasket and the connecting ring. At this time, the connecting ring drives the A limiting ring and the straight pipe to clamp together with the threaded sleeve driving the B limiting ring and the drainage elbow, further increasing the sealing performance and stability between the drainage elbow and the straight pipes.

[0016] When a blockage occurs inside the drain bend, turn the valve to discharge the blocked wastewater along the filter pipe and drain head. The filter pipe effectively discharges wastewater at different levels. Then, rotate the drain cover and drain pipe to disassemble them, allowing the blockage debris to fall into the inside of the waste storage container. This allows for the effective sequential treatment of the blocked wastewater and debris, preventing wastewater and debris from flowing out together and contaminating the workers' clothing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5This utility model provides a technical solution: a corner elbow for building drainage, including a drainage elbow 1, with straight pipes 3 assembled at both ends of the drainage elbow 1, a reinforcing sleeve 2 sleeved on the outside of the drainage elbow 1, and a connecting mechanism between the drainage elbow 1 and the straight pipe 3. The connecting mechanism includes a sealing gasket 16, a B-limiting ring 17, a threaded sleeve 12, and a reinforcing component. A threaded groove is opened on the outside of the straight pipe 3 and at one end close to the drainage elbow 1. Both ends of the outside of the drainage elbow 1 are fixed with B-limiting rings 17. A threaded sleeve 12 is rotatably connected to the outside of the B-limiting ring 17. The inside of the threaded sleeve 12 and at one end away from the drainage elbow 1 is threadedly connected to the threaded groove. A sealing gasket 16 is assembled between the drainage elbow 1 and the straight pipe 3.

[0026] When in use, when the drain elbow 1 is assembled between two straight pipes 3, the threaded sleeve 12 is rotated to drive the drain elbow 1 and the straight pipe 3 to be threadedly connected. This causes the threaded sleeve 12 to squeeze the drain elbow 1 and the straight pipe 3 together. A sealing gasket 16 is provided between the drain elbow 1 and the straight pipe 3, thereby improving the sealing effect between the drain elbow 1 and the straight pipe 3 and preventing sewage from seeping out.

[0027] The reinforcement assembly includes an A-limiting ring 10, a connecting ring 11, a handwheel 13, a pressure pad 14, and a linkage rod 15. The A-limiting ring 10 is fixed to the outside of the straight pipe 3. The connecting ring 11 is rotatably connected to the outside of the straight pipe 3 and above the A-limiting ring 10. The linkage rod 15 is rotatably connected to both sides of the outside of the threaded sleeve 12. The handwheel 13 is rotatably connected to the end of the linkage rod 15 away from the threaded sleeve 12.

[0028] A pressure pad 14 is slidably connected to the outside of the linkage rod 15. The bottom end of the pressure pad 14 is slidably connected to the top of the connecting ring 11. The bottom end of the handwheel 13 is rotatably connected to the pressure pad 14. The connection point between the linkage rod 15 and the handwheel 13 is offset from the center of the handwheel 13. The pressure pad 14 effectively applies pressure to the connecting ring 11, increasing the clamping effect between the connecting ring 11 and the A limit ring 10 and the straight pipe 3 and the drain elbow 1.

[0029] Specifically, the drain elbow 1 and the straight pipe 3 are sealed together by the threaded sleeve 12 to prevent instability in the connection between the drain elbow 1 and the straight pipe 3. Then, the handwheel 13 drives the linkage rod 15 and the threaded sleeve 12 to rotate, while the linkage rod 15 slides with the connecting ring 11. At this time, the handwheel 13 uses its protruding part to squeeze the pressure pad 14 and the connecting ring 11. At this time, the connecting ring 11 drives the A limit ring 10 and the straight pipe 3 to clamp together with the threaded sleeve 12 and the B limit ring 17 and the drain elbow 1, further increasing the sealing and stability between the drain elbow 1 and the straight pipe 3.

[0030] When it is necessary to disassemble and replace the drain elbow 1, the handwheel 13 is rotated in the opposite direction to release the pressure on the pressure pad 14 and the connecting ring 11. Then the linkage rod 15 is disengaged from the inside of the connecting ring 11, and the threaded sleeve 12 is rotated in the opposite direction, thereby effectively replacing and disassembling the drain elbow 1.

[0031] A drain pipe 4 is fixed to the bottom of the drain elbow 1 and the reinforcing sleeve 2. A drain cover 6 is rotatably connected to the bottom of the drain pipe 4. A garbage storage cylinder 5 is fixed to the top of the inner side of the drain cover 6. The outer side of the garbage storage cylinder 5 is slidably connected to the drain pipe 4. A filter pipe 7 is fixed to the top of the inner side of the drain cover 6 and located inside the garbage storage cylinder 5. A drain head 8 is fixed to the bottom of the filter pipe 7 through the drain cover 6. A valve 9 is assembled on the outer side of the drain head 8.

[0032] Specifically, when a blockage occurs inside the drain bend 1, the valve 9 is turned to discharge the blocked sewage along the filter pipe 7 and the drain head 8. The filter pipe 7 effectively discharges sewage of different levels. Then, the drain cover 6 and the drain pipe 4 are rotated to disassemble them, and the blocked garbage falls into the inside of the garbage storage container 5 to effectively dispose of the garbage and prevent sewage and garbage from flowing out together and contaminating the workers' clothes.

[0033] The following is the usage process of the corner elbow for building drainage provided by this utility model: By aligning the two ends of the drainage elbow 1 with the straight pipe 3, the interface gap is filled by the sealing gasket 16, and the threaded sleeve 12 is rotated so that its inner side is threadedly connected with the threaded groove on the outer side of the straight pipe 3, which causes the drainage elbow 1 to be squeezed against the straight pipe 3. The sealing gasket 16 achieves a preliminary seal to prevent sewage leakage. When the handwheel 13 is rotated, the connection point between the linkage rod 15 and the handwheel 13 is off-center, and the protruding part of the handwheel 13 squeezes the pressure pad 14. The pressure pad 14 pushes the connecting ring 11 to slide downward, and the connecting ring 11 drives the A limiting ring 10 and the straight pipe 3, forming a bidirectional clamping force with the B limiting ring 17 driven by the threaded sleeve 12 and the drainage elbow 1, which further enhances the sealing and stability of the interface.

[0034] When the drain bend 1 is clogged, open the valve 9 on the outside of the drain head 8. Sewage is filtered through the filter pipe 7 and discharged through the drain head 8, preventing debris from being discharged directly. Then, rotate the drain cover 6 to disassemble it from the drain pipe 4. The clogged garbage falls into the garbage storage cylinder 5 due to gravity. After cleaning the garbage storage cylinder 5, reinstall the drain cover 6 and close the valve 9 to complete the sewage discharge operation and prevent sewage and garbage from overflowing and polluting the environment.

[0035] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
