A fixed connector for solid-wall pipe layout

Abstract

The invention discloses a solid wall pipe distribution fixing connector which comprises a bucket-shaped outer barrel and a screw rod, wherein the bucket bottom of the outer barrel is provided with a via hole; the thread end of the screw rod extends into the outer barrel through the via hole; a fixed bulge plug and a movable bulge plug are sequentially arranged in the outer barrel from inside to outside, the fixed bulge plug is sheathed on the screw rod in a sliding way, and the movable bulge plug is connected onto the screw rod by thread; the fixed bulge plug and the movable bulge plug are respectively in a circular truncated cone shape; the small end surface of the fixed bulge plug is opposite to the small end surface of the movable bulge plug; a bulge barrel is arranged in the outer barrel; the inner walls of the two ends of the bulge barrel are respectively provided with an inner conical surface, and the two inner conical surfaces are respectively matched with the outer surface of the fixed bulge plug and the outer surface of the movable bulge plug. The solid wall pipe distribution fixing connector is simple in structure; the bulge barrel can be extruded outwards by the fixed bulge plug and the movable bulge plug by operating the screw rod, so that the functions of extruding and closely supporting a pipeline can be reached, and a whole longer pipe can be dragged and drawn; the solid wall pipe distribution fixing connector is simple and convenient to operate, is capable of effectively accelerating the construction speed, lightening the labor intensity and improving the operation efficiency, and is safe, convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of pipe laying and installation tools, and in particular relates to a solid-wall pipe laying and fixing connector. Background technique [0002] With the development of the national economy, the scale of cities has gradually expanded, and the pace of renewal and transformation of urban municipal pipe networks has also accelerated. The conventional underground pipeline laying method mostly adopts the open and cut method of laying pipes. However, due to the influence of geographical location and construction environment, as well as the obstruction of underground buildings, traffic congestion, and complex layout of underground pipelines, the method of laying open-cut pipes can no longer meet the requirements of construction conditions, and sometimes even cannot be constructed. Existing main pipelines such as electricity, telecommunications, network, and communication are all laid underground in the city. In or...

Problems solved by technology

[0003] Regardless of whether it is in the construction of pipe layout by open-cut method or in the construction of pipe layout without excavation, because the pipe is too long, it is impossible to drag the welded pipe to the construction position, and each section of pipe needs to be put into the preset position in turn , and then the pipes are hot-melt welded into one in turn, and a welding operation space needs to be reserved at each welding position. The operation of the workers is labor-intensive and time-consuming, and the power supply needs to be continuously moved according to the station, which brings great inconvenience to the construction. extremely inefficient
