Description

A kind of opposite opened jointing clip
Technical field
The utility model relates to a kind of opposite opened jointing clip that the concrete pipeline connects that is used for.
Background technique
At present, the pipeline in concrete construction connects, and mostly is to connect realization with two split type clips, and existing clip has plenty of the bolt flange formula, and promptly two ends all use bolt, nut to connect, though firm and reliable connection, dismounting is very time-consuming, and efficient is low; Have plenty of fast joint type,, have only the sealing of one seal ring or near conical surface seal, its sealing effect is all not so good though dismounting is fast.And existing clip design, generally making the gap c=4~5mm between the ends of tubes, this is disadvantageous, because such gap c is bigger than normal, concrete is leaked, the ring wear aggravation had both reduced sealing effect, had shortened the working life of seal ring again.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of existing clip, provide a kind of can fast assembling-disassembling, can reach the quick jointing clip of opposite opened of desirable seal effect again, the compression shock in the time of can also cushioning transmission and concrete transmission simultaneously.
The technical solution of the utility model is as follows: a kind of opposite opened jointing clip, comprise left half clip, right half clip, seal ring, a left side half clip, right half clip all are semi-annular shape, in the middle of its internal surface a semi-circular recesses is arranged respectively, the bilateral symmetry of groove, and be provided with limit, twice oblique angle, limit, twice oblique angle is different angles with bottom land, be provided with seal ring in the groove, it is circular that seal ring is, and its cross section is c-shaped; A left side half clip and right half clip two ends are connected in one by pin shaft structure.
Left half clip and right half clip are connected in one by bearing pin in the utility model, make and leave c=1~2mm reasonable clearance between the ends of tubes that is connected; Described sealing ring material adopts nitrile rubber, its mechanical strength height, stretching rate is strong, and wear-resisting, and seal ring integral body is circular, but can be a nonocclusive annulus, from a side of annulus it is cut, comprise crosscut and cut sth. askew, so that can load and unload fast, its cross section is c-shaped, and promptly Huan internal surface caves in inwards; A left side half clip, right half clip all are semi-annular shape, a semi-circular recesses is respectively arranged in the middle of its internal surface, the bilateral symmetry of groove, and be provided with limit, twice oblique angle, be respectively two different angle α, β, this is to aim at the pipe end unique design adorning special seal ring and cooperate required connection, this can make sealing effect better, compression shock in the time of cushioning transmission and concrete transmission again, angle is the design on limit, β oblique angle simultaneously, also brings convenience for assembling; Left and right sides two halves clip except that have only a cephalic par structure different, all the other are all the same, this also brings convenience to technology and manufacturing.
As further improvement of the utility model, a left side half clip and right half clip the bearing pin bindiny mechanism at two ends up and down are designed to: there are two asymmetric otic placodes with holes at left half clip, one end middle part, right half clip is identical with it with end construction, when left and right sides two halves clip is connected, these two pairs of otic placodes stagger alternate identical, connect with bearing pin to be integral; There is the otic placode of two symmetries at half clip the other end middle part, a left side, right half clip has the otic placode with holes of two symmetries with the end middle part, connect by bearing pin in the middle of one end of swing bolt through hole being embedded in two otic placodes of right half this end of clip, the externally threaded end of swing bolt band sticks in the middle of two otic placodes of left half clip with the end, then by the nut fixing and locking.

Embodiment
Embodiment 1
As shown in Figure 1, a kind of opposite opened jointing clip, comprise left half clip 1, swing bolt 2, nut 3, right half clip 4, seal ring 5, bearing pin 6, a left side half clip 1 is connected in one by bearing pin 6 with right half clip 4, leave reasonable clearance c=1~2mm between the ends of tubes that is connected; Seal ring 5 materials are nitrile rubbers, its mechanical strength height, and stretching rate is strong, and wear-resisting, and it is circular that outward appearance is, but a non-full circle, but from a side it is cut off, so that can load and unload fast, its cross section is c-shaped, shown in 5 among Fig. 2; A left side half clip, right half clip all are semi-annular shape, a semi-circular recesses is respectively arranged in the middle of its internal surface, the bilateral symmetry of groove, and be provided with limit, twice oblique angle, be respectively two different angle α, β, as shown in Figure 3, this is to aim at the pipe end unique design adorning special seal ring 5 and cooperate required connection, and this can make sealing effect better, the compression shock in the time of cushioning transmission and concrete transmission again, angle is the design on limit, β oblique angle simultaneously, also brings convenience for assembling; Left and right sides two halves clip except that have only a cephalic par structure different, all the other are all the same, this also brings convenience to technology and manufacturing.There are two asymmetric otic placodes with holes at half clip, one end middle part, a left side, shown in Fig. 4,5; Right half clip is identical with it with end construction, shown in Fig. 6,7; When left and right sides two halves clip was connected, these two pairs of otic placodes staggered alternate identical, connected with bearing pin to be integral; There is the otic placode of two symmetries at half clip the other end middle part, a left side, right half clip has the otic placode with holes of two symmetries with the end middle part, connect by bearing pin in the middle of one end of swing bolt through hole being embedded in two otic placodes of right half this end of clip, the externally threaded end of swing bolt band sticks in the middle of two otic placodes of left half clip with the end, then by the nut fixing and locking, as shown in Figure 8.
Now be described further: as shown in Figure 8 in conjunction with real embodiment, when reality connects, the ends of tubes that need are connected aligns, put seal ring, open clip and fasten two pipes, then the inner surface recesses of two clips and both sides angle thereof are that the limit, oblique angle of α is tightly pushed seal ring with the ends of tubes periphery that is connected, and play seal action; Gap between the gap of seal ring inner chamber, clip and tube end and the gap between the ends of tubes, the compression shock in the time of cushioning transmission and concrete transmission again; Two clip angles are the sealing that matches of limit, oblique angle and the ends of tubes side conical surface that is connected of β, and so just form compound sealing with preceding sealing, and its sealing effect is very good.Swing bolt one end that will be fixed on right half clip then directly sticks in the middle of two otic placodes of left half clip correspondence, again with the nut fixing and locking; During dismounting,, again swing bolt is broken off with the fingers and thumb out, opened clip and get final product as long as nut is unscrewed and need not pull down.What need special instruction is, because a side of annular seal ring disconnects, so loading and unloading are especially easily and fast, and because of the gap very little (being designed to c=1mm) between the ends of tubes that connects, reaching clip internal surface angle is the design on the limit, oblique angle of β, so do not influence its sealing effect.The quick jointing clip of opposite opened of the present utility model shows through use, has both reached desirable sealing effect, and dismounting is convenient and swift again, and is very practical.
