Telescopic and bendable gas monitoring meter connecting structure

Abstract

The invention discloses a telescopic and bendable gas monitoring meter connecting structure, including a telescopic pipe, a first hard pipe and a second hard pipe; pipe heads are arranged at the two ends of the telescopic pipe correspondingly; a pipe head is arranged at one end of the first hard pipe, and at least one clamping groove is formed in the other end of the first hard pipe; a pipe head is arranged at one end of the second hard pipe, and at least one clamping key is arranged at the other end of the second hard pipe; the first hard pipe sleeves one end of the telescopic pipe, and the inner surface of the pipe head of the first hard pipe is in sealing contact with the outer surface of the pipe head at one end of the telescopic pipe; and the second hard pipe sleeves the other end ofthe telescopic pipe, and the inner surface of the pipe head of the second hard pipe is in sealing contact with the outer surface of the pipe head at the other end of the telescopic pipe. The connecting structure has the beneficial effects that flexible application of gas monitoring meters such as a pressure meter and a density meter is achieved through the combination of flexible connection and afixing manner, the product performance is improved, and upgrading and updating of novel products are developed.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a connection structure for a gas-insulated switchgear or an airtight container and a metering and detecting device. Background technique [0002] At present, the connection methods of gas monitoring meters such as pressure gauges and density meters commonly used in gas-insulated switchgear at home and abroad mainly include: metal hard pipes or plastic hoses. One end of the connecting pipe is respectively connected to the check valve at the container end or the gas charging interface, and the other end is connected to a pressure gauge, a density gauge or other gas monitoring meters. [0003] One of the advantages that gas insulated switchgear products are widely used and recognized by users is their compact structure and small size. The connection methods of gas monitoring meters such as conventional pressure gauges and density meters have affected the space layo...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a flexible and curved gas monitoring meter connection structure, which can realize that the connecting pipe is not affected by external force under normal operating conditions; The airtightness from the fixed state to the stretching and bending process is not affected; it solves the viewing problem of pressure gauges, density gauges or other gas monitoring meters without a viewing angle, and solves the problem that monitoring meters cannot be operated due to the small space.
