Embodiment
Below in conjunction with accompanying drawing structure of the present utility model is described.
Figure 3 shows that the utility model sour jujube embraces formula cable turnover linear sealing apparatus structure schematic representation.Seal arrangement of the present utility model comprises tightening nut 1, rubber seal 2, ratchet securing means 3 and base 4.Cable 8 and seal arrangement are fixed on (not shown) on the cable hut by rubber washer 5, adapter sleeve 6 and tightening nut 7.
As depicted in figs. 1 and 2, ratchet securing means 3 is the frustoconic shape sleeve-like structure, and the side of round platform front end has a plurality of breach, constitutes a plurality of ratchets 32, is evenly distributed in the frustum cone side.Ratchet 32 front ends have engagement portion 31.
In the embodiment shown in fig. 1, ratchet 32 is 16.
Rubber seal 2 is the frustoconic shape sleeve-like structure, and the front end of rubber seal 2 outer side surfaces has groove 21, and the front inner diameter of rubber seal 2 and cable 8 are complementary.
Rubber seal 2 is socketed in the ratchet securing means 3, makes between ratchet securing means 3 and the rubber seal 2 and realizes interference fit.The engagement portion 31 of ratchet 32 is connected to groove 21 places.
Tightening nut 7 has internal thread, and rubber washer 5 and adapter sleeve 6 are successively set on tightening nut 7 tops.
Base 4 is columnar structured, has front end 41, rear end 42 and boss 43.Front end 41 carries out the transition to rear end 42 by boss 43.Boss 43 has outer edge of giving prominence to the external diameter direction 431 and the inside edge 432 of giving prominence to internal diameter direction, is used to realize limit function.
Front end 41 is an annular spigot towards preceding extreme direction, and front end 41 comprises outer cylinder 411 and inner cylinder 412.The internal diameter of the inside edge 432 of boss 43 and the external diameter of cable 8 are complementary.Ratchet securing means 3 and rubber seal 2 place front end 41 inside, are fastened on the inside edge 432 of boss 43.
Outer cylinder 411 and inner cylinder 412 combine with the inside edge 432 of boss 43, make front end 41 be " U " type on axial cross section.Radial clearance between outer cylinder 411 and the inner cylinder 412 is enough to insert ratchet securing means 3 and rubber seal 2.Outer cylinder 411 has outside thread, matches with the internal thread of tightening nut 1.The external diameter of the internal diameter of inner cylinder 412 and cable 8 is complementary.
Rear end 42 is an annular spigot towards the back extreme direction, and the internal diameter of rear end 42 is greater than the external diameter of cable 8.Rear end 42 has outside thread.Rear end 42 is plugged in the tightening nut 7, the outer edge 431 and rubber washer 5 clampings of boss 43, and the outside thread of rear end 42 matches with the internal thread of tightening nut 7, and base 4 is fixed on the tightening nut 7.
Rubber washer 5 and adapter sleeve 6 are located between tightening nut 7 and the boss 43.When base 4 screwed, rubber washer 5 was squeezed and deforms, and eliminated the gap between base 4 and the adapter sleeve 6, water-tight.
Tightening nut 1 has internal thread, and its inner tip opening is a cone structure.Tightening nut 1 and base 4 are by being threaded.
When mounted, cable 8 is penetrated tightening nut 1, rubber seal 2, ratchet securing means 3, base 4, rubber washer 5, adapter sleeve 6 and the tightening nut 7 that combines.At this moment, between tightening nut 1 and the front end 41 for unscrewing state.When tightening nut 1 screws, the front end of the conical surface of tightening nut 1 inner tip opening contact ratchet 32, and extruding ratchet 32.Ratchet 32 homogenizing that are equally spaced tightening nut 1 applied pressure, make tightening nut 1 be applied to pressure equal and opposite in direction on a plurality of ratchets 32.
The ratchet 32 that is equally spaced is fastened on the surface of rubber seal 2, makes pressure size that rubber seal 2 is subjected to evenly, and tightening nut 1 applied pressure is converted into coupling mechanism force between ratchet securing means 3 and the rubber seal 2.Rubber seal 2 deforms because of being subjected to uniform coupling mechanism force, is wrapped in the surface of cable 8, eliminates the slit between rubber seal 2 and the cable 8, water-tight.Simultaneously, because the engagement portion 31 of ratchet 32 is connected to groove 21 places, make to be difficult between ratchet 32 and the rubber seal 2 producing sliding, locking effect is better.
Continue turn tightening nut 1, the surface of contact of the conical surface of its inner tip opening and ratchet 32 further increases, and makes that the coupling mechanism force between rubber seal 2 and the ratchet securing means 3 increases, and has reached good sealing effect.
The ratchet seal arrangement 3 that is provided with of the present utility model, homogenizing the pressure of tightening nut 1, make ratchet seal arrangement 3 act on the rubber seal 2 the coupling mechanism force size evenly, sealing effect is better.
In the present embodiment, rubber washer 5, adapter sleeve 6 and tightening nut 7 are to be used for base 4 is fixed on cable hut.In use, base 4 also can be fixed on the cable hut by other modes, for example utilizes bolton.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
