Flexible connecting piece of cast-iron drain pipe

Abstract

The invention relates to a flexible connecting piece of a cast-iron drain pipe. The flexible connecting piece comprises a rubber ring and is characterized in that the flexible connecting piece further comprises a smooth steel strip, lug plates, a via hole clamping plate, a buckling hole clamping plate, bolts and a conducting strip, the two ends of the smooth steel strip are provided with the lug plates respectively, the two outer sides of the lug plates are provided with the via hole clamping plate and the buckling hole clamping plate respectively, the bolts are installed in through holes in the via hole clamping plate, the lug plates and the buckling hole clamping plate in a penetrating mode, and the conducting strip is installed on the smooth steel strip. The flexible connecting piece is scientific and reasonable in structural design, has the advantages of being high in flexible force resistance, long in service life, wide in application range, simple in structure, low in production cost and resistant to corrosion, and has high innovativeness.

Description

technical field [0001] The invention relates to a pipe connecting piece, in particular to a flexible connecting piece of a cast iron drainage pipe. Background technique [0002] The structure of the flexible connector of the traditional cast iron drainage pipe is relatively complicated. It is composed of a steel belt with corrugated surface, two worm-type clamps and a rubber ring. Fastening adjustment of the steel belt to the workpiece. However, in the actual use process, there are the following problems: 1. The corrugated structure of the steel strip affects the fastening performance of the steel strip itself, making it less flexible; 2. Relying on the clamp to fasten the steel strip, the The hoop is easy to be squeezed and deformed, which shortens its service life; 3. The worm-type adjustment method, due to the limitation of the worm torque, makes its scope of use limited; 4. For static electricity generated during construction or lightning strikes Or the leaked electric...

The corrugated structure of the steel strip affects the fastening performance of the steel strip itself, making it less flexible; 2. Relying on the clamp to fasten the steel strip, the The hoop is easy to be squeezed and deformed, which shortens its service life; 3. The worm-type adjustment method, due to the limitation of the worm torque, makes its application range limited; 4. For static electricity generated during construction or lightning strikes Or the leaked electricity does not have a structural setting with a dredging function, which poses a threat to the safety of the building; 5. The overall structure is too complicated and the production cost is high
