Abstract

The utility model relates to a rectangular turning connector. The connector, which can be decomposed freely, comprises an upper plate and a lower plate. After the connector is decomposed into the upper plate and the lower plate, the two plates can be assembled into an integrated rectangular turning pipe connector again. The upper plate and the lower plate are like two sections cut at the middle seam of the L-shaped side of an ordinary rectangular turning pipe connector, and are equipped with four straight sections of buckling seams and two arc sections of flat seams at a mutual edge of the two plates respectively. As the rectangular turning connector can be discomposed freely, wiring becomes easier and wires does not be abraded or over-pulled easily, so as to ensure higher security. A pipe-through rope and a wire-leading rope are not needed in wiring. Moreover, the procedure of bending pipe processing is omitted, and no tool is needed for installation and dismounting of the rectangular turning connector. Thus, the wire and pipe layout construction course is greatly simplified, the engineering progress can be accelerated, and the construction cost can be reduced.

The purpose of this utility model is to provide a kind of right-angled bend pipe joint, this joint makes to be laid in the construction at fulgurite, pipeline cooperates the circuit demand can have 90 degree of any amount to turn, and pipeline is when carrying out 90 degree turnings, can be directly with 90 degree right-angled bends, need not carry out curve bend processing, and when so the pipeline laid of mode carries out cable wiring manufacture therein, more convenient operation, and can better guarantee to manage the safety of inner cable.

The technical solution of the utility model is: a kind of right-angled bend pipe joint, it is characterized in that: this joint comprises can resolve into

slices

4 and 5 liang of parts of following sheet freely, after the decomposition last slice 4 and following sheet 5 be free to be re-combined into a complete right-angled bend pipe joint again, last slice 4 and following sheet 5 as be both two parts that a common right-angled bend pipe joint is cut open along the L type centre joint of its side, last slice 4 and following sheet 5 fastening that respectively is provided with four sections straightways at the edge that interosculates stitch the flat seam 2 of 1 and two section arc, fasten seam 1 and be provided with back-off groove 6, sewing at four sections fastenings of last 4 all respectively has a slice to press off the wing 3; With last slice 4 and after the fastening of following sheet 5 seam 1 aims at mutually, the pressing of exerting oneself slightly, 4 and 5 just can be combined into an integral body, form a complete right-angled bend pipe joint; The right-angled bend pipe joint of combination as inwardly depress be located at last slice 4 press off the wing 3, then can open the fastening seam 1 of combination easily, be broken down into slices 4 and following sheet 5.

Advantage of the present utility model is: because it is free to decompose reorganization, when adopting this right-angled bend pipe joint to lay pipeline, no matter what 90 degree pipeline has turn, all can freely lay with the right-angled bend pipe joint that combines, need not consider to be provided with halfway junction box, when carrying out conduit wiring, each right-angled bend pipe joint is taken apart, article one, script is connected up by N the pipeline that 90 degree are turned and has just become a pipeline wiring of being made up of N+1 section straightway or little bending curvature line segment, after wiring is finished, each right-angled bend pipe joint is recombinated, and whole pipeline has promptly recovered the state of complete closure.When adopting existing cable and pipeline thereof to lay construction technique, consider resistance and friction that pipeline is turned and brought, utilization of space has certain restriction in the pipe; And when adopting the utility model, because the segmentation wiring has not had the big resistance and the friction of turning and being brought of pipeline 90 degree, this restriction will obtain certain loose, promptly in the pipeline of same specification, can lay the cable of more or bigger specification, or under same cabling requirement, can use the more tubing of small dimension, engineering cost will greatly reduce.Because the segmentation wiring has not had the big resistance and the friction of turning and being brought of pipeline 90 degree, it is lighter that wiring will become, and cable is not easy to be worn, to pull during construction, and its safety is more secure.Because the segmentation wiring has not had the big resistance and the friction of turning and being brought of pipeline 90 degree, when having certain rigidity (the pipeline length of straightway or little bending curvature line segment be no more than certain limit and cable itself) under many circumstances, the pipeline wiring will no longer need to use tube opening cable and lead cable, adding the dismounting of having saved bend pipe procedure, right-angled bend pipe joint need not be by any instrument, whole cable and pipeline thereof are laid work progress and are simplified significantly, project progress can be accelerated, and construction cost can reduce.Under some construction occasion, adopting existing cable and pipeline thereof to lay construction technique can't realize or be difficult to realize that satisfactory pipeline lays, then can easier deal with problems after using the utility model, for example: adopt existing cable and pipeline thereof to lay construction technique, to require tubing to be processed into camber at right angle turn with certain bending radius, normal conditions require r 〉=3D, r is the inner bend radius of tubing in the following formula, D is the external diameter of tubing, to in the metope that two fans intersect vertically, lay a hidden pipe, the camber bend pipe will be hidden the corner then must dig out darker groove on body of wall, groove depth H should satisfy:

If employing the utility model, the groove depth H=D of demand under the kindred circumstances, obviously, under same groove depth restrictive condition, maximum available tubing specification is original 2 times behind employing the utility model, and the pipeline that existing construction technique much can't be laid the approach of need seeking in addition in this case can be easy to lay after adopting the utility model.
