Description

Anti-overflow and anti-leakage connecting pipe for daily life sewer

Technical Field

The utility model relates to the technical field of daily pipeline connection, in particular to a sewer overflow-proof connecting pipe which is used as an overflow-proof device in pipeline connection, has a remarkable using effect particularly in sewer pipelines of kitchens and toilets in families and office buildings, and can well avoid the overflow phenomenon among pipelines.

Background

In daily life, a reserved pipe of a kitchen or a toilet is connected with a main sewer pipe through a telescopic sewer hose. At present, most of drainage hoses sold in the market are PP polypropylene corrugated pipes, drainage corrugated pipes produced by different manufacturers have different telescopic lengths, and the structures and the shapes of the drainage corrugated pipes are basically the same. In practical use, the problem is often encountered, and once the sewer is blocked, water flows out from the gap between the tail end of the sewer corrugated pipe and the sewer main pipe. Although the water overflow preventing devices are of a tube thread expansion type or a rubber sealing type, the structures of the water overflow preventing devices are complex, and the production cost is high.

Disclosure of Invention

The utility model aims to solve the problem of overflow leakage after a sewer pipe is blocked, and designs an overflow leakage prevention connecting pipe.

The utility model is realized by adopting the following technical scheme:

the utility model provides a daily life is with offal anti-overflow connection pipe, includes the bellows, bellows end connection anti-overflow connection union coupling, anti-overflow connection union coupling comprises internal diameter tube face and external diameter tube face, form U type draw-in groove between internal diameter tube face and the external diameter tube face.

Further preferably, after the upper end of the sewer pipe is inserted into the U-shaped clamping groove of the anti-overflow connecting pipe head in a clearance fit mode, the retractable clamp is additionally arranged outside the outer diameter pipe face.

The overflow problem between sewer pipe way mainly can be solved to this device, in order to guarantee this function, reforms transform the end of current sewer hose, and terminal pipe fitting covers on the sewer pipe through adopting U type draw-in groove structure (forming through internal diameter pipe face and external diameter pipe face), and for reaching this purpose, U type draw-in groove and sewer pipe adopt clearance fit, and clearance range is 0.1~0.3 mm. The pipe fitting material is PP polypropylene material, and in order to facilitate inserting the downcomer, the wall thickness of the terminal U type draw-in groove structure of pipe fitting is 1~1.5mm, can be fine like this reach the anti-overflow water efficiency. If the sewer pipe has reverse water (the water pressure reaches more than 0.07 MPa) with certain pressure, the U-shaped clamping groove can be taken off from the sewer pipe, and in order to solve the problem, after the U-shaped clamping groove is installed, a retractable clamp can be additionally installed on the outer wall of the U-shaped clamping groove.

The utility model has the following practical application effects:

1. simple structure and convenient operation

The anti-overflow device is simple in structure, and in actual use engineering, the anti-overflow function can be achieved only by inserting the U-shaped clamping groove of the anti-overflow connecting pipe into the upper end of the sewer pipeline.

2. Simple maintenance and replacement

The device has stable structure and is not easy to damage. Once the phenomenon of overflow because of ageing takes place, can install the clamp additional, if install the clamp already, just need change this device. When the device is replaced, the damaged device is simply pulled out, and a new device is inserted.

3. Low manufacturing cost

The device has simple structure and low manufacturing cost.

The pipeline connecting device is reasonable in design, simple in structure, convenient to use and low in cost, and has good practical application value.

Detailed Description

The following detailed description of specific embodiments of the utility model refers to the accompanying drawings.

A sewage overflow-proof connecting pipe for daily life is disclosed, as shown in figures 1 and 2, and comprises a corrugated pipe 1, wherein the end part of the corrugated pipe 1 is connected with an overflow-proof connecting pipe head 2, the overflow-proof connecting pipe head 2 is composed of an inner diameter pipe surface 3 and an outer diameter pipe surface 4, and a U-shaped clamping groove is formed between the inner diameter pipe surface 3 and the outer diameter pipe surface 4; as shown in fig. 3 and 4, after the upper end of the downcomer 6 is inserted into the U-shaped slot of the anti-overflow connector 2 in a clearance fit manner, the retractable clamp 5 is additionally arranged on the outer diameter pipe surface 4.

The end pipe fitting of the corrugated pipe is designed into the U-shaped clamping groove, which is the core technical point of the anti-overflow connecting pipe, and the overflow problem during drainage can be simply and efficiently treated.

When the overflow-proof connecting pipe is used specifically, as shown in fig. 5a, the overflow-proof connecting pipe is inserted into a sewer pipe, as shown in fig. 5b, the joint at the tail end of the sewer overflow-proof leaking pipe is inserted into the sewer pipe, and the sewer pipe is tightly wrapped by the U-shaped clamping groove, as shown in fig. 5c, when water flows through, the overflow phenomenon can be effectively prevented due to the wrapping of the U-shaped clamping groove. As shown in fig. 5d, when the sewer pipe has a reverse water phenomenon (the water pressure reaches more than 0.07 MPa) with a certain pressure, the U-shaped sewer clamp groove can be taken off from the sewer pipe, and in order to solve the problem, a stainless steel clamp can be additionally arranged on the outer wall of the U-shaped clamp groove to enhance the sealing performance, so that the phenomenon of water overflow prevention is achieved.

During specific preparation, the wall thickness of an inner diameter pipe surface 3 and an outer diameter pipe surface 4 of the U-shaped clamping groove are both 1-1.5 mm; the clearance range between the U-shaped clamping groove and the sewer pipe is 0.1-0.3 mm. The corrugated pipe 1 is made of PP polypropylene.

The sewer anti-overflow leakage connecting pipe designed by the utility model achieves the anti-overflow leakage function by improving the structure at the tail end of the corrugated pipe. The anti-overflow drain pipe device for the sewer is simple in structure, convenient to use, and convenient to produce, maintain and maintain, and can be connected with various pipelines such as a kitchen, a wash platform, a washing machine and the like in the future.
