Novel pre-buried leakage-proof connector for building drainage

Abstract

The invention discloses a novel pre-buried leakage-proof connector for building drainage. The pre-buried leakage-proof connector comprises a connecting body and an adjusting ring component and is characterized in that the upper body and the lower body are coordinated to form the connecting body, the adjusting ring component comprises an inner adjusting ring and an outer adjusting ring, the connecting body is provided with vertical draining through holes, the outer adjusting ring is connected with the upper body in a coordinated manner, and the inner adjusting ring is fastened to the outer adjusting ring. The novel pre-buried leakage-proof connector has the advantages that the upper body and the lower body are copperatively connected in a fastened manner, risks of water leakage and odor leakage can be avoided, and construction efficiency can be increased; a water sealing plate is arranged on each of the inner adjusting ring and the outer adjusting ring, and water sealing structures canbe formed to prevent odor return; the water sealing structures can be in a working state constantly by an automatic water supplementing structure; a return-preventing structure can prevent sewage fromoverflowing from the draining holes or blocking the draining holes; flow guide ribs and a slope type draining concave ring can prevent the sewage and waste from blocking lateral draining holes; the inner adjusting ring and the outer adjusting ring can adjust the situation that upper reserved holes do not correspond to lower reserved hole due to construction.

Description

【Technical field】 [0001] The invention relates to the technical field of drainage pipes, in particular to a novel pre-buried leak-proof joint for building drainage. 【Background technique】 [0002] In the commercial houses we use, there are sewage pipes distributed in kitchens, balconies, bathrooms and other places. The current installation method of sewage pipes is generally: install the pre-embedded pipes that can be connected to the drainage pipes in advance. The position where the drainage riser is required , and then connect the upper and lower drain pipes or other indoor pipelines. With the extensive use of embedded joints, more and more embedded joints of different structures have appeared on the market, but the existing embedded pipe fittings have the following problems: First, the embedded seat of the embedded joint (embedded The main body) is composed of two parts. The lower main body is connected to the drain pipe downstairs, and the upper main body is connected t...

Problems solved by technology

With the extensive use of embedded joints, more and more embedded joints of different structures have appeared on the market, but the existing embedded pipe fittings have the following problems: First, the embedded seat of the embedded joint (embedded The main body) is composed of two parts. The lower main body is connected to the drain pipe downstairs, and the upper main body is connected to the adjustment ring. The upper and lower main bodies are bonded with special glue. After the product is installed for a period of time, the glue is affected by the environment and sewage. There is a gap between the upper and lower bodies, and sewage, odor, etc. will leak from the gap, and will seep into the ground for a long time, or water will leak from the lower floor, causing inconvenience; the second is that there are drainage holes on the adjustment ring in the embedded joint for drainage. The sewage seeping into the bottom floor, but the sewage, waste, odor, etc. in the drain pipe will also pass through the adjustment hole, seep to the ground or block the drain hole, resulting in poor indoor air or drainage failure
