Embodiment
Referring to figs. 1 through Fig. 3, the utility model embodiment is described further.
Cable water joint described in the present embodiment, as shown in Figure 1, comprise joint body 1, nut 3, tight loop 4, sealing ring 2, joint body 1 includes the first external screw thread 12, second external screw thread 13 and the gear flange 11 between the first external screw thread 12 and the second external screw thread 13 in tubular, the other end of the relative gear flange 11 of the second external screw thread 13 is provided with tight lock part 14, tight loop 4 is connected with the first external screw thread 12, identical with prior art with upper part, therefore seldom repeats;
As shown in Figure 1, the inwall of described joint body 1 is provided with the annular flange flange 15 of radial convex near tight lock part 14, one end of described sealing ring 2 is provided with the cambered outwards spacing flange 21 in footpath, being lining in tight lock part 14 in described sealing ring 2 and spacing flange 21 is connected to the side of relative first external screw thread 12 of annular flange flange 15, in described joint body 1, being provided with the fixed mechanism for being pressed in by spacing flange 21 in annular flange flange 15.
Optimize, described fixed mechanism is sleeve 5, and sleeve 5 is provided with external screw thread, is provided with internal thread in joint body 1, and sleeve 5 is threadedly connected in joint body 1 and one end and is formed with spacing flange 21 and abut.Sleeve 5 is threaded connection in joint body 1, and sleeve 5 one end and spacing flange 21 when proceeding in joint body 1 are formed conflicts, tight by turning of sleeve 5, thus is pressed in annular flange flange 15 by spacing flange 21.By this kind of mode, sleeve 5 can proceed to or produce, and facilitates the replacing of sealing ring 2.If certainly do not adopt said structure, such as rivet, screw etc. also can be adopted directly the structure that spacing flange 21 is pressed in annular flange flange 15 to be fixed.
Effect of the present utility model is, abandon the structure of conventional seals circle 2 only collar-shaped, the utility model is provided with the spacing flange 21 of evagination in its one end, and be provided with the annular flange flange 15 of radial convex near tight lock part 14 at the inwall of joint body 1, joint body 1 is put in one end that sealing ring 2 can arrange the first external screw thread 12 from joint body 1, make to be lining in tight lock part 14 in joint body 1, and make its spacing flange 21 be connected to the side of relative first external screw thread 12 of annular flange flange 15.Make between sealing ring 2 and annular flange flange 15, to form the position limiting structure stoping sealing ring 2 to be deviate to tight lock part 14 direction by adopting such scheme.And be also provided with fixed mechanism in joint body 1, can be used for spacing flange 21 to be pressed in annular flange flange 15 thus to ensure that spacing flange 21 does not depart from annular flange flange 15.By adopting technique scheme, carry out effective fixing to sealing ring 2, can ensure that in the process of extracting cable sealing ring 2 has not taken off tight lock part 14, thus prevent the loss of sealing ring 2, result of use is good.
Further, as shown in Figure 3, the heel of described tight lock part 14 is arranged to its end in drawing in axis direction part, makes the multiple shell fragments forming tight lock part 14 to axis direction portions incline.
Its effect is, tight lock part 14 is draw in centre when contacting with the curved portions 31 on nut 3 thus tightened up by sealing ring 2, in prior art, tight lock part 14 is all straight settings, be not easy to draw in bent intermediate, therefore will reach tight lock part 14 in prior art to draw in and need to apply larger torsion to nut 3 and make tight lock part 14 stretch in nut 3 further, this process is very hard.The utility model is by being arranged to tight lock part 14 in advance by heel to end in the structure of drawing in axial portions, make the outer wall initial condition Xia Jiuxiang center local dip of tight lock part 14, when proceeding to nut 3, tight lock part 14 is easier to be gathered to centre, and it is more laborsaving, convenient to use.
Further optimization, as shown in Figure 2, the inwall of described sealing ring 2 is coaxially provided with some annular protrusions 22.Sealing ring 2 not only needs to be issued in the state of tightening up the effect contacting with cable surface and seal, also be use as cable clamp simultaneously, the clamping action between sealing ring 2 and cable can be improved by the annular protrusion 22 arranged at sealing ring 2 inwall, prevent cable from being pullled and cause wiring place to loosen.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
