Embodiment
The description in orientation of the present utility model is carried out according to orientation shown in Figure 5, also is the direction up and down that direction up and down shown in Figure 5 is description, and a side of court of Fig. 5 institute is the place ahead, and a side who deviates from Fig. 5 is the rear.Be called the inboard with the side near the seal ring center, be called the outside with the side away from the seal ring center.
(embodiment 1)
See Fig. 1, Fig. 2, Fig. 5 and Fig. 7, seal ring 1 of the present utility model is the rubber integral piece.Seal ring 1 comprises main part 11 and bump 12.Main part 11 integral body are Circular Plate shape, and bump 12 integral body are the round platform hull shape.Bump 12 is positioned at the central position of main part 11, and is connected internally on the main part 11, and is coaxial with main part 11, and described axis is the central axis 10 of seal ring 1.The inner chamber of the bump 12 of round platform hull shape is as wire outlet hole 13, and this wire outlet hole 13 also is the central hole of seal ring 1, and the axis of described central hole also is the central axis 10 of seal ring 1.See Fig. 4 to Fig. 7, wire outlet hole 13 comprises from top to bottom the first hole section 13-1 and the second hole section 13-2 of coaxial setting successively.The first hole section 13-1 is cylindrical.The second hole section 13-2 is frustoconic shape.The aperture of the first hole section 13-1 (also being the diameter of column part) is identical with the diameter of the upper end-hole of the second hole section 13-2.The upper end-hole of the first hole section 13-1 is positioned at the highest position of bump 12.The lower end mouth of the second hole section 13-2 is positioned at its lowest position of bump 12, and is positioned on the same horizontal plane with the bottom surface of main part 11.When the aperture of the first hole section 13-1 is to use with the corresponding hole section in the line footpath of the cable after extruding.
See Fig. 1 to Fig. 7, seal ring 1 is provided with the lineal shape joint-cutting of regulating seam 14 to the conduct of cutting self rear portion to the left bottom along upper right, and should adjustings stitches 14 front end and wire outlet hole 13 and be connected, and this adjusting is stitched 14 rear end and extraneous space and is connected.Two tangent plane 14-1 that the formation of seal ring 1 is regulated seam 14 fit mutually, and the angle α of the central axis 10 of each tangent plane 14-1 and seal ring 1 be 20 degree to 70 degree, preferred 30 degree are to 60 degree, further preferred 40 degree are to 50 degree (present embodiment be 45 spend).
When the utility model uses, pulling cable passes the second hole section 13-2 and the first hole section 13-1 of the wire outlet hole 13 of seal ring 1 successively, when pulling cable with extrude after the joint of cable during near seal ring 1, unclamp the parts of corresponding fixed seal ring 1, make seal ring 1 radially upwards not have constraint with week.The joint line enters earlier among the second bigger hole section 13-2 of the aperture of wire outlet hole 13 of seal ring 1 smoothly, after the guiding through the second hole section 13-2, when the less second hole section 13-2 in the aperture of wire outlet hole 13 of seal ring 1 is prepared to enter in the joint, because the external diameter of joint is usually greater than the aperture of the second hole section 13-2, thereby the corresponding site that the bump 12 of seal ring 1 can be withstood in the joint makes seal ring 1 along the tangent plane 14-1 dislocation of regulating seam 14, produce corresponding deformation, thereby the aperture of the second hole section 13-2 is variable big, and the joint can be passed through the second hole section 13-2 smoothly.The joint is after passing through the second hole section 13-2, because the restoring force of seal ring 1 self, the second hole section 13-2 reverts to the size in former aperture, corresponding with the line footpath of cable after extruding, at this moment, the parts of the corresponding fixed seal ring 1 that closes again make seal ring axially, radially with week constraint is arranged all upwards, two tangent plane 14-1 of the adjusting seam 14 of seal ring 1 fit tightly mutually, play good seal action.
Above embodiment is only for the usefulness that the utility model is described; but not to restriction of the present utility model; person skilled in the relevant technique is under the situation that does not break away from spirit and scope of the present utility model; can also make various conversion and variation; can also transform accordingly according to the inspiration of above-described embodiment in the concrete application process, so all technological schemes that are equal to all should be included within the scope of patent protection of the present utility model.
