Description

Solid wall pipe connecting pipe fitting Technical Field The utility model relates to the field of pipe connecting structures, in particular to a solid wall pipe connecting pipe fitting. Background The straight pipe type solid wall pipe is widely applied to the fields of water delivery systems, sewage disposal systems, municipal drainage and the like at present. When a plurality of pipelines are paved, any two adjacent straight pipes are required to be communicated by using a connecting structure, so that a complete water pipe is assembled. The existing straight pipe can be connected through a sleeve structure, when the two straight pipes are connected, the two straight pipes are respectively inserted into the sleeve from two sides of the sleeve, the ends of the two straight pipes are aligned and abutted, the straight pipes and the sleeve are generally made of plastic materials through rubber rings, and in the cold-hot temperature change process of an application environment, dislocation is easily caused by connection of the straight pipes and the sleeve due to expansion with heat and contraction with cold, so that the sealing performance is reduced or even lost. Disclosure of utility model The utility model aims at solving the problems in the background technology, and provides a solid wall pipe connecting pipe fitting which is in interference sealing connection with two solid wall pipes, wherein the two solid wall pipes are distributed in a clearance way, the influence of heat expansion and cold contraction is eliminated, and the stability and the connection tightness of a connecting position are ensured. The technical scheme includes that the solid wall pipe connecting pipe fitting comprises a sleeve and a boss part, wherein the boss part is integrally connected to the inner side of the sleeve and protrudes inwards, two groups are arranged side by side along the axial direction of the sleeve, and the inner side surface of the boss part is in interference connection with the outer peripheral surface of the solid wall pipe. Preferably, the device further comprises a connecting part which connects the sleeve with the solid wall pipe. Preferably, the sleeve has flared portions at both ends. Preferably, the sleeve has a plurality of through holes. Preferably, the connecting part is a convex ring part integrally connected to the inner side surface of the sleeve, and an electrothermal fuse is arranged in the convex ring part. Preferably, the connecting part is a limiting ring part protruding outwards from the outer circumference of the sleeve, and the limiting ring part is provided with a limiting groove gradually inclining outwards from the middle part of the sleeve to the outer end. Preferably, the sleeve inner peripheral surface has an annular clamping groove, and the clamping groove is located between the connecting portion and the boss portion. Preferably, a group of pressure measuring injection holes and pressure holes are arranged in the middle of the sleeve. Compared with the prior art, the utility model has the following beneficial technical effects: According to the utility model, the two groups of boss parts are respectively in interference sealing connection with the two solid wall pipes, the sealing effect is improved by using the rubber ring, the gaps of the two solid wall pipes are distributed, the influence of thermal expansion and cold contraction is eliminated, and the stability and the connection tightness of the connection position are ensured.
