Description

Sewage pipe inspection port convenient to assemble and disassemble Technical Field The utility model relates to the technical field of sewer pipe overhauling, in particular to a sewer pipe inspection port convenient to assemble and disassemble. Background In the design process of the sewage pipeline, considering the reasons of internal filtration and blockage, an inspection port is usually required to be arranged in a proper area of the main pipeline for subsequent dredging and maintenance, but the design of the metal branch pipeline with larger diameter cannot be performed by referring to the traditional plastic pipe for processing threads for sealing due to the diameter size and the wall thickness of the metal branch pipeline, the installation and the disassembly are relatively time-consuming in a bolt fixing mode, and in the fixing process, the position of the cover body needs to be continuously adjusted to ensure better tightness, so that the operation is relatively difficult. Disclosure of utility model Aiming at the technical defects, the utility model provides the sewage pipe inspection port which is convenient to assemble and disassemble, the movable ring is triggered to displace by the tightening piece, the end cover is driven to seal the branch pipe port, the operation is simple and quick, the operation time is shortened, the positioning of the end cover can be realized quickly by means of connecting the pull rod with the movable ring, and the sealing effect is good without frequently adjusting the position. The technical scheme includes that the device comprises a main pipeline, a branch pipeline, an end cover and a movable ring, wherein the branch pipeline is welded on the main pipeline and communicated with the main pipeline, the branch pipeline is symmetrically provided with tightening members, the movable ring is in sliding connection with the branch pipeline and is in contact with the tightening members, and the end cover is provided with a pull rod which is connected with the movable ring. Preferably, the tightening member comprises a support lug and an adjusting screw, the support lug is fixedly connected with the branch pipeline, the adjusting screw is in threaded connection with the support lug, and the end part of the adjusting screw is in contact with the movable ring. Preferably, the end of the adjusting screw is provided with a spherical surface. Preferably, at least one sliding rail is arranged on the branch pipeline, and a sliding groove matched with the sliding rail is arranged on the inner circle of the movable ring. Preferably, one end of the sliding rail, which is close to the main pipeline, is provided with a positioning screw. Preferably, the movable ring is provided with a clamping groove, one end of the clamping groove is enlarged in size and forms a circular channel, and the end part of the pull rod is provided with a chuck penetrating into the circular channel. Preferably, the other end of the clamping groove is provided with a limit groove on the surface of the movable ring close to the direction of the main pipeline. Preferably, a sealing gasket is arranged at the pipe orifice of the branch pipe. Preferably, a fixing groove for installing the sealing gasket is formed in the pipe orifice of the branch pipe. Preferably, a lantern ring is arranged on the contact surface of the end cover and the branch pipe. Compared with the prior art, the utility model has the following advantages: 1. After the pull rod is connected with the movable ring for positioning, the movable ring is triggered to displace towards the direction of the main pipeline by operating the two tightening members, so that the sealing between the end cover and the branch pipeline can be completed, the operation is simple and convenient, the position of the end cover is not required to be frequently adjusted, and the operation time is saved; 2. The connection among the pull rod, the chuck and the clamping groove can quickly realize the positioning of the end cover, improve the mounting or dismounting speed, and simultaneously prevent the end cover from reversing due to the connection of the limiting groove and the chuck, and improve the stability after connection; 3. The sliding rail is connected with the sliding groove, so that the guiding and positioning functions of the movable ring are realized, and the design of the positioning screw can prevent the sliding of the sliding rail and the sliding groove during use, so that the limiting function is realized; 4. The installation of sealing gasket can improve the leakproofness to the pipeline after the end cover compresses tightly to through the fixed slot of processing department sealing gasket, improve the stability after the sealing gasket installation, prevent to drop.
