Background
The operations of joint connection in pipeline construction are generally: the two nozzles to be connected are aligned and connected by installing a special connecting piece. However, the positions of the pipe joints may be in various places, so that the conventional clamping pieces are inconvenient to operate when in use, for example, in the patents with chinese patent publication No. CN201748094U and the name "clamp type pipe joint", the disclosed clamp type pipe joint is not only the type of joint connecting piece, but also the two ends of the joint connecting piece are locked by bolts in a matching manner. This kind of structure need all fix both ends, and work load is great, and this kind of structure both ends all need set up the flange moreover to set up with bolt complex through-hole, make the area of flange great relatively like this, also relatively more in the use of raw materials.
Further, as in the chinese patent application No. 2009801204520 entitled "clamp fitting for clamping together coupling sleeves on pipes," it discloses a clamp fitting having a hinge at one end. Although the other end of the hinge is only locked and fixed by bolts during installation, the hinged end needs manpower or mechanical equipment to be assembled in advance.
In an existing pipeline connection structure, as shown in fig. 1, the pipeline connection structure generally includes a pipeline 1 and a
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
