Description

The linkage structure of current connecting pipeline

Technical field

The utility model relates to a kind of linkage structure of current connecting pipeline, is meant a kind of current connecting tube structure that comprises lock tieing, a connection tube, a collar and a waterstop pad of a hexagon nut especially.

Background technique

The linkage structure of the current connecting pipeline of generally commonly using please refer to as shown in Figure 1, it is mainly with hexagon nut lock tieing 10, opening inner edge in the one end forms an arc inner edge 11, cooperate an internal diameter to be contained within the lock tieing 10 with the rigid outer arcuate copper sheathing 30 that is connected water pipe 20 cooperations, the outer arced surface 31 of this outer arcuate copper sheathing 30 touches with arc inner edge 11 subsides of lock tieing 10, and a rigid connection water pipe 20 stretches in lock tieing 10 and the arc copper sheathing 30, the turnover water pipe 40 that one end opening is had interior chamfering 41 stretches in the lock tieing 10, and touch with chamfering in it 41 and the outer arcuate copper sheathing 30 and cambered surface 31 subsides of opposite side, when turn lock tieing 10 inwardly enters turnover water pipe 40, and force outer arcuate copper sheathing 30 to tighten rigid fast water receiving pipe 20, finish converged functionality.

More than the shortcoming of this linking water pipe structure following shortcoming is arranged:

1, is forced to bundle with rigid outer arcuate copper sheathing and ties on rigid connection water pipe 20 external diameters, firmly to hard bundle knot and soundness is not good gets loose easily.

2, except getting loose easily, it is good and leak easily firmly hard contact bundle to be tied its adaptation yet.

3, it is only applicable to the turnover water pipe that open end has interior chamfering.

Because there are many shortcomings in the above-mentioned structure of commonly using, so the dealer is that in addition improvement design becomes as shown in Figure 2 structure, it mainly forms an inward flange 12 in hexagon nut lock tieing 10 1 end openings, cooperate a brace that the connection tube 50 that enlarges neck 51 is arranged, in its lock tieing 10 of packing into and enlarge the hypomere of neck 51 below with it and pass the inward flange 12 of locking tieing 10, be connected with one flexible pipe 60 wear and cooperate a metal collar 61 in addition roll extrusion tighten combination; Be connected water pipe and can on the expansion neck 51 of this connection tube 50, put the waterstop pad 52 on a plane by the head of convex column type, and in the turnover water pipe 40 screw-in lock tieing 10 with the straight opening end 42 of a brace, with its opening end 42 packing waterstop pads 52, be connected and the merit able one of packing sealing and reach.

But above-described structure also has following shortcoming to exist:

1, because of waterstop pad usually by the opening end packing thereby the distortion of turnover water pipe, so, run out attached to opening end easily and drop unclamping lock during tieing.If refill, this moment, strained waterstop pad was difficult for smooth abutting on the connection tube, in case turnover water pipe packing and can not get stagnant water effect completely easily causes and leaks or waterstop pad damages.Lacking waterstop pad will leak, very trouble.

2, its plane shape waterstop pad is only applicable to the turnover water pipe of flat opening end.

Summary of the invention

Therefore, how to improve the design of the linkage structure of generally commonly using the current connecting pipeline, make it can adapt to the turnover water pipe structure of different openings, and waterstop pad is difficult for dropping, can reach preferable adaptation, leak resistance again and in conjunction with fastness might as well, be the difficulty place that solves for the utility model institute desire row.

The inventor is not good in view of linkage structure adaptation and the fastness of generally commonly using the current connecting pipeline, and be connected the bad adaptability of water pipe and many shortcomings that waterstop pad drops out easily, be engaged in this skill experience for many years improvement design in addition with it, inquire into and study sampling test through designing in many ways, and repeatedly revise improvement, create the utility model.

Main purpose of the present utility model, provide a kind of linkage structure of current connecting pipeline, it has a flange in connection tube epimere head upper end, periphery is oblique shape and only avoids it to stretch into intake pipe and reduce leakage-proof effect on the waterstop pad card, and flange is the periphery of oblique shape and the conical surface of waterstop pad is symmetric figure, and being beneficial to opening end has the turnover water pipe turnover of arc angling and the suitable shape sealing that reclines.

Another purpose of the present utility model provides a kind of linkage structure of current connecting pipeline, and this waterstop pad is the cone rubber pad that a periphery has plain-straight-face flange, and the turnover water pipe lock tieing inner contact that can adapt to tool arc angling opening end engages; Plain-straight-face flange that can also periphery engages with the turnover water pipe of flat type opening end lock knot, and applicability is wide.

The purpose of this utility model is achieved in that a kind of linkage structure of current connecting pipeline, comprises the compositions such as lock tieing, a connection tube, a collar and a waterstop pad of a hexagon nut; The lock tieing of described hexagon nut at one end opening forms an inward flange, connection tube enlarges neck by one and is divided into two sections, epimere is that head and hypomere are the lacing section that car becomes to have some anti-skidding check rings, connection tube is packed in the lock tieing, and it enlarges that neck is stuck within the inward flange and lacing section passes the inward flange of lock tieing, be provided with back the tightening of a metal collar one end grafting with a water pipe sleeve and finish combination by means of roll extrusion, the upper end that is positioned at the connection tube epimere head of lock tieing inside has one to make waterstop pad be blocked the flange of only avoiding it to drop out, its periphery is oblique shape and is nested with a waterstop pad, waterstop pad is the cone rubber pad that a periphery is provided with plain-straight-face flange, and the oblique shape periphery of its central conical surface and connection tube epimere head upper end is symmetric figure.The turnover water pipe spiro lock tieing inner contact sealing that can adapt to tool arc angling opening end engages; And plain-straight-face flange that can also periphery pastes counter stop water with the turnover water pipe spiro lock knot of straight opening end and engages.
