Description

Municipal pipeline connection structure Technical Field The utility model relates to a municipal pipeline connecting structure. Background Municipal pipelines refer to various functional pipelines paved underground in urban public areas, and are mainly used for meeting the requirements of urban water supply and drainage, power supply, communication transmission and the like, and the pipeline systems are important components of urban infrastructure. Most length of common pipeline is fixed, and through being in the same place two pipelines, common operation is welding and flange joint, and wherein, the welding exists difficult dismantlement maintenance, increases later maintenance cost, and flange joint usually needs to be through welding, bolted connection etc. mode mounting flange at the both ends of pipeline, and perhaps the ring flange on this pipeline will be thrown away or need additionally dismantle and then utilize it again when pipeline damage appears and need be changed. Therefore, how to reduce the number of parts connected to the pipeline and further avoid wasting resources when discarding damaged pipelines is a problem to be solved by those skilled in the art. Disclosure of Invention Aiming at the defects of the prior art, the utility model aims to provide a municipal pipeline connecting structure for realizing connection between a first pipeline and a second pipeline by sleeving a connecting piece. The connecting piece is arranged in a sleeve shape and is positioned on the periphery of the first pipeline and the second pipeline, the left side of the connecting piece is connected with the first pipeline in a buckling way, the right side of the connecting piece is connected with the second pipeline in a buckling way, the first sealing ring is positioned between the first pipeline and the connecting piece, and the second sealing ring is positioned between the second pipeline and the connecting piece. The connecting piece comprises an inner mounting groove, a plurality of limiting inserting blocks are arranged on the left side of the mounting groove in a protruding mode in the radial direction, and limiting slots are formed in the first pipeline corresponding to the limiting inserting blocks. The utility model is further arranged that the first pipeline further comprises a connecting section positioned on the right side of each limiting slot, and the left side of the connecting section is propped against each limiting plug block. The utility model is further characterized in that the connecting section is provided with a plurality of inserted bars in a protruding mode towards the right along the circumferential direction, and the second pipeline is provided with inserting grooves corresponding to the inserted bars respectively. The utility model is further characterized in that a plurality of fixing plates are installed on the connecting piece, which is positioned on the right side of the installation groove, in a circumferential rotation manner, each fixing plate comprises a limiting section for inserting the second pipeline, and the connecting piece is slidably installed with a matched inserting block for inserting the fixing plate corresponding to each fixing plate. The utility model is further provided with: the connecting piece is characterized by further comprising a matched spring, wherein one end of the matched spring is fixed with the corresponding matched plug block, the other end of the matched spring is fixed with the connecting piece, plug posts for inserting the matched springs are respectively fixedly provided with a contact plate, the connecting piece is provided with sliding grooves corresponding to the contact plates, the connecting piece further comprises a fixed section fixed with the matched springs, and one end of each contact plate is propped against the corresponding fixed section.
