图1是本实用新型中隔水套管快速接头的半剖结构示意图;图2是本实用新型中隔水套管快速接头的侧视示意图;图3是本实用新型中隔水套管快速接头另一实施例的侧视示意图。 FIG 1 is a half cross-sectional structural diagram of the quick connector of the present invention in riser; FIG. 2 is a schematic side view of the quick connector of the present invention in the riser; FIG. 3 is a riser in the present invention quick connector schematic side view of another embodiment.

如图1所示,外接头1在其内壁上设有一卡环槽10,该卡环槽10用于设置弹性卡环3。 1, the outer joint 1 is provided with a snap ring groove 10 on its inner wall, the snap ring groove 10 for the snap ring 3 is provided. 同时,外接头1在其内壁面上靠近卡环槽10的一侧设有一凹槽11,该凹槽11用于卡设密封圈4,另外,为了使外接头1与内接头2在连接时较为容易地撑握位置,在外接头1的内壁两端设有两导引锥面12和13。 At the same time, a joint on its outer side close to the inner wall surface of the snap ring groove 10 is provided with a recess 11, the recess 11 is provided for locking the sealing ring 4, Further, in order to make the outer 1 and the inner joint connected to the joint 2 relatively easy to hold grip position, the inner wall of the outer terminal ends of the guide 1 is provided with two tapered surfaces 12 and 13. 内接头2在其内壁上设有一凹槽20,该凹槽20与外接头1的卡环槽10相对应。 The connector 2 is provided with a recess 20 on its inner wall, the groove 20 with a snap ring groove 10 corresponding to the outer joint. 同时,与外接头1内壁面上的导引锥面12、13相对应,在内接头2的外壁面上设有两圆锥面21和22。 Meanwhile, the outer surface of the connector inner wall 12 and 13 corresponding to the tapered guide, the outer wall surface of the nipple 2 is provided with two tapered surfaces 21 and 22. 当内接头2与外接头1相卡合连接时,凹槽20刚好与卡环槽10相对应,同时,圆锥面21、22与导引锥面12和13紧密贴合,并使卡设在卡环槽10内的弹性卡环3卡设在凹槽20与卡环槽10内,从而使外接头1与内接头2可靠地锁合在一起。 When the card with the connector 21 when engaged with the outer joint connection, coincides with a groove 20 corresponding to the snap ring groove 10, while the conical surface 21 and tapered surface 12 and the guide 13 in close contact, and the card is provided Flexible card in the snap ring groove 10 provided in the ring groove 3 the card 20 and the snap ring groove 10, so that the outer and the inner joint connector 12 locked together securely.

如图1和图2所示,外接头1在卡环槽10的底部设有三个长条形穿孔14,与该长条形穿孔14相对应,在弹性卡环3上设有三螺孔30,利用该螺孔30、穿过长条形穿孔14设有三个螺栓5。 1 and 2, the outer joint 1 is provided at the bottom of the snap ring groove 10 of the three elongated perforations 14, the perforations 14 strip corresponds to the length, the elastic locking ring 3 is provided with three screw holes 30, with this screw hole 30, through the perforations 14 is provided with three elongated bolt 5. 长条形穿孔14在其内部可设有密封水塞,以进一步防止海水进入到隔水套管6内部。 Elongated perforations 14 may be provided inside the sealing plug of water, to further prevent water entering the interior of riser 6.

在组装与安装隔水套管6时,先将外接头1和内接头2分别焊接在隔水套管6的两端,并在外接头1的卡环槽10内卡设有弹性卡环3,此时,该弹性卡环3处于收紧状。 In assembling the mounting riser 6, the first connector 1 and the outer joint 2 are welded to both ends of the riser 6 and the outer joint in a card 10 is provided with a snap ring groove snap ring 3, in this case, the snap ring 3 is tightened shape. 接着将根隔水套管6对接,即将一根隔水套管的内接头2插入到另一根隔水套管端部的外接头1内部,当内接头2上的凹槽20与外接头1上的卡环槽10对齐时,弹性卡环3会自动落入到内接头2的凹槽20内,从而将两根隔水套管6可靠地锁合在一起,进而可以将多根隔水套管6连接在一起。 Next, the riser 6 abutting the root, i.e. a riser connector 2 is inserted into the interior of the outer joint portion of the other end of the riser 1, when the groove on the nipple 220 and the outer joint when aligned with the snap ring groove 110 on, snap ring 3 will automatically fall into the recess 20 of the nipple 2, so that the two riser 6 securely locked together, and thus may be a plurality of compartments water sleeve 6 connected together. 当探井完成后,大多数隔水套管6都需要重新使用,因此,在拆卸时只需在提起隔水套管后,旋拧三个螺栓5,使弹性卡环3均匀地张开,即脱离内接头2,从而可以方便地将内接头2与外接头1分离开,进而将隔水套管分开。 After completion of exploration, most riser 6 need to re-use, therefore, when disassembling only after bringing riser, three threaded bolt 5, so that the elastic snap ring 3 evenly spread, i.e., from the connector 2, thereby easily fitting the nipple 2 and the outer 1 separated from the riser and further apart.

如图3所示,为了使弹性卡环3能够均匀张开,在弹性卡环3上的螺栓可以是五个螺栓5。 3, in order to make uniform elastic locking ring 3 can be opened, the bolt 3 in the snap ring 5 may be five bolts.

综上所述,本实用新型中的快速接头在用于隔水套管后,其具有抗剪切力大,安全系数较高,并由两组锥面进行轴向定位,使得隔水套管在海流中冲击的稳定性较好。 In summary, the present invention is a quick connector in the riser, which have a large shear forces, high safety factor, two axially positioned by the tapered surface, so that the riser better impact on the stability of ocean currents. 另外,本实用新型中的快速接头操作简便、省时省力,明显可提高工作效率。 In addition, the present invention is simple and quick connectors, saving time and effort, can significantly improve efficiency.

另外,上述虽然对本实用新型中快速接头的具体实施例进行了描述,但是并不能作为本实用新型的保护范围,由于作为本技术领域的熟练技术人员,对其进行稍加修饰或改变是较为容易的,但这些修饰与改进均没有脱离本实用新型的设计精神,凡是在不脱离本实用新型中的设计精神所作出的等效变化或修饰均应认为落入本实用新型的保护范围。 Further, although the above-described specific embodiments of the present invention has been described quick connector, but not as the scope of protection of the present invention, since the present skilled in the art, be modified or changed a little easier but all these modifications and improvements without departing from the spirit of the design of the present invention, all without departing from the present invention is equivalent to a change in the spirit of the design made or modified shall be deemed to fall within the scope of protection of the present invention.
