Description

MPP power tube connecting piece Technical Field The utility model relates to the technical field of power tube connection, in particular to an MPP power tube connector. Background The MPP pipe adopts modified polypropylene as a main raw material, has the characteristics of high temperature resistance and external pressure resistance, is suitable for medium and low voltage transmission line cable calandria pipes below 10KV, is produced with a certain length during production, and ensures the transportation requirement, but generally a plurality of pipelines are connected during construction so as to ensure the construction requirement. The prior art has the following problems that 1, the existing power pipes are connected through connecting pieces, most of the connecting pieces are fixed in a squeezing mode directly outside the connecting position of two MPP power pipes, the fixing mode is complicated and the MPP power pipes are easy to break, and 2, the existing connecting pieces are low in tightness during connection, and the condition that cables in the pipes are affected with damp or bitten by insect damage is easy to occur. To solve the above-mentioned problems, it is desirable to provide a new MPP power pipe connector. Disclosure of Invention The utility model aims to provide an MPP power tube connecting piece which can realize quick connection of power tubes and has high tightness. In order to achieve the above purpose, the utility model provides an MPP power tube connecting piece, which comprises an outer cylinder body and an inner cylinder body, wherein the middle section of the inner side wall of the outer cylinder body is fixedly connected with the outer side wall of the inner cylinder body, the two ends of the outer side wall of the outer cylinder body are connected with fixing pieces, the two end faces of the inner cylinder body are respectively provided with a slot and a positioning column, the central axis of each slot coincides with the central axis of the inner cylinder body, the slots are matched with the connector structure of the end part of the MPP power tube, the minimum distance from the positioning column to the central axis of the inner cylinder body is larger than the radius of the outer ring of each slot, the positioning columns are matched with the positioning jack structure of the end part of the MPP power tube, and the outer side wall of the MPP power tube is provided with a threaded slot matched with the fixing piece structure. Preferably, the inner cylinder is made of rubber. Preferably, the outer cylinder is made of MPP. Preferably, the fixing member is a bolt. Preferably, the inner cylinder is bonded to the outer cylinder.
