Description

Straight wall tubular product third order structure connector Technical Field The utility model relates to the field of pipe connecting structures, in particular to a straight-wall pipe third-order structure connector. Background The corrugated pipe is widely applied to the fields of water delivery systems, sewage disposal systems, municipal drainage and the like. When laying a plurality of pipelines, any two adjacent corrugated pipes are required to be communicated by using a connecting structure, so that the complete pipeline is assembled. The prior corrugated pipe communication mode is mainly a mode of connecting the inner side of an inserted sleeve, the periphery of the corrugated pipe is in sealing connection with the inner wall of the sleeve through a rubber ring, but after the corrugated pipe is used for a long time, offset dislocation conditions between the corrugated pipe and the sleeve can possibly occur, and if the dislocation degree is large, the sealing performance can be affected. Disclosure of utility model The utility model aims to solve the problems in the background art, and provides a connector with a straight-wall pipe three-step structure, which can be blocked at the end part of a corrugated pipe, limit the dislocation range between the connector and the corrugated pipe and prevent the sealing performance from being influenced by larger dislocation degree. The technical scheme is that the straight-wall pipe three-step structure connector comprises a sleeve and a locking platform, wherein the sleeve comprises an outer cylinder part, a connecting ring part and an inner cylinder part which are sequentially connected, the locking platform is arranged on the outer peripheral surface of the inner cylinder part, the outer side surface of the locking platform is a circular interference connecting surface, and the inner diameter of the outer cylinder part, the outer diameter of the locking platform and the outer diameter of the inner cylinder part are sequentially reduced. Preferably, the outer cylindrical portion is provided with a plurality of through holes. Preferably, the outer end of the outer barrel portion has a flared portion. Preferably, the outer cylinder has a first engagement groove on its inner circumferential surface and a second engagement groove on its outer circumferential surface. Preferably, the outer barrel part is provided with a plurality of groups of jacks, each group of jacks comprises two clamping holes, clamping fasteners are arranged at the clamping holes in a clamping manner, and the clamping fasteners are of U-shaped structures. Preferably, the outer barrel portion has a convex ring portion protruding outward, and the convex ring portion has a stopper groove gradually inclined outward in a direction from an outer end of the inner barrel portion to an outer end of the outer barrel portion. Preferably, the connecting ring portion, the inner cylinder portion and the locking stand are integrally connected. Preferably, the outer barrel portion or the connecting ring portion is provided with a set of pressure measuring injection holes and pressure holes. Preferably, the outer and inner cylindrical portions are provided with reinforcing ribs on their outer circumferences. Compared with the prior art, the utility model has the following beneficial technical effects: In the utility model, for two connected corrugated pipes, one corrugated pipe is inserted into the inner side of the outer cylinder part, the other corrugated pipe is sleeved on the outer periphery of the inner cylinder part, and the inner peripheral surface of the other corrugated pipe is inserted into the interference connection surface of the outer side of the locking platform in an interference manner, so that the connection firmness is improved. The opposite ends of the two corrugated pipes are respectively positioned at two sides of the connecting ring part, the connecting ring part limits the range of offset dislocation of the two corrugated pipes, and the sealing performance of the rubber ring cannot be affected due to the fact that the dislocation of the two corrugated pipes is large.
