Embodiment
For ease of understanding technology contents of the present utility model, just by reference to the accompanying drawings its working condition and principle are described further below.
Execution mode one
The special mounting rod of a kind of U-shaped seat as depicted in figs. 1 and 2, comprises two L-type trailing arms 4, brace table 5, anchorage bar 6, outer bar 1 and interior bar 1.Its for the U-shaped seat 1 of the bird-scaring unit tapered pole 3 that comprises pressing plate 2 and be connected on pressing plate.Tapered pole 3 is passed from bottom to top by the bellmouth on U-shaped seat underarm, and the axial length of obvious tapered pole is greater than the axial length of bellmouth, and makes the tapering of the two consistent.Moreover also it is emphasized that the action principle of tapered pole is |: the hardness number that tapered pole makes metal material is less than the hardness number that U-shaped seat makes material, like this when tapered pole is subject to upwards push-pull effort effect, tapered pole can be subject to the squeezing action of bellmouth and produce contraction distortion and bellmouth forms interference fit, thus fastness, reliability that bird-scaring unit is installed can be ensured, the external world can be withstood and constantly rock effect (wind).
Described L-type trailing arm 4 symmetry is fixedly mounted on the left and right sides of brace table 5.The horizontal arm of described L-type trailing arm 4 arranges through hole respectively, rubber cup 41 is installed in through hole.Down, the inner chamber of described rubber cup 41 is conical cavity and chamber draws in from top to bottom gradually for the tapered and large end of the outer wall of described rubber cup 41.
Described rubber cup 41 filled in by the through hole lower end on L-type trailing arm 4 and with L-type trailing arm 4 secure fit, in use the lower end plug of described tapered pole 3 is blocked in the conical cavity of rubber cup 41, thus U-shaped seat 1 is fixed on brace table 5.
It should be noted that, the conical cavity degree of depth of the rubber cup 41 of setting should be enough dark, ensure that U-shaped seat 1 is stablized not have in L-type push arm 4 upper end and obviously rock.Before being connected with L-type trailing arm 4 by U-shaped seat 1, need adjustment fastening bolt 11 that the outer wall of tapered pole 3 is just contacted with corresponding bellmouth 12.
One group of fixed pulley group is also respectively arranged with in the left and right sides of described brace table 5.Described fixed pulley group comprises the first pulley 51, second pulley 52 and stay cord 53, and one end of described stay cord 53 is fixed on rubber cup 41 lower end of corresponding side, and the other end freely hangs down after walking around the first pulley 52, second pulley 53 successively.Stay cord 53 should have enough length, at least along a distance above the lower end extending to outer bar 1, ensure on the other hand hand-held outer bar 1 time another hand can catch the lower end of stay cord 53.
During use, first make tapered pole 3 coordinate with rubber cup 41, after in the cross-arm notch of U-shaped seat 1 being inserted electric tower, pull described stay cord 53 that rubber cup 41 and tapered pole 3 are departed from downwards.
Described brace table 5 is nested with the upper end at described outer bar 1.
Described outer bar 1 is provided with axial through hole.Make described interior bar 1 can do axially rectilinear movement and around axial-rotation by relatively described outer bar 1 in the axially extending bore that described interior bar 1 is assemblied in described outer bar 1.
For ensureing the axially directed property of the internal bar of axocoel 1 of outer bar 1, and reduce the friction of interior bar 1 outer wall and outer bar one 71 weeks wall contact portions, bearing should be fixedly installed respectively in the top and bottom of described interior bar 1, make the inner ring of bearing and interior bar 1 interference fit, outer ring contacts with the axocoel wall of outer bar 1 and coordinates.This modified node method makes the use of this special mounting rod more laborsaving, extends the life-span used.
Be fixedly connected with the upper end of described interior bar 1 after the lower end of described anchorage bar 6 penetrates the certain axial distance of axocoel of described outer bar 1, make described anchorage bar 6 can do axially rectilinear movement and around axial-rotation by relatively described outer bar 1.In the upper surface of described anchorage bar 6, six axial prism blind holes are set.
Equally, for ensureing the axially directed property of the axocoel of outer bar 1 to anchorage bar 6, and reduce the friction of anchorage bar 6 outer wall and outer bar one 71 weeks wall contact portions, bearing is nested with at the middle part of described anchorage bar 6, and make to adopt interference fit form between anchorage bar 6 and bearing inner race, the outer ring of bearing contacts with the axocoel wall of outer bar 1 and coordinates, and arranges bearing (ball) cover in the upper end of described outer bar 1.
Except arranging outside bearing between anchorage bar 6 and outer bar 1, for achieving the above object, as shown in Figure 1, can also realize by arranging fairlead 61.The internal diameter of fairlead 61 is consistent with the external diameter of anchorage bar 6.For the outer wall of a section that the inner surface of fairlead 61 and anchorage bar 6 coordinate with it, need fine finishining, with ensure the two coordinate after axiality, reduce friction when moving axially.Described fairlead 61 is fixedly mounted on the axocoel place, upper end of described outer bar 1.Described fairlead 61 and outer bar 1 will ensure the axiality of installing.Described anchorage bar 6 lower end is fixedly connected with described interior bar 1 through after described fairlead 61.
Execution mode two
As shown in Figure 3, be different from above-mentioned execution mode, in the present embodiment, the axial length of this special mounting rod can regulate.For this reason, it is also provided with outer bar 2 72 and interior bar 2 82, and externally the structure of bar 1 and interior bar 1 has done adaptation improvement.
Described interior bar 2 82 is six prism bars, and described outer bar 2 72 is for having the tubular rod of axially extended cylinder chamber.The footpath, chamber, column type chamber of described outer bar 2 72 is consistent with the outer bar of described outer bar 1.
From the lower surface of described interior bar 1, six axial prism holes are set, make described interior bar 2 82 can do axial rectilinear movement in six prism holes of described interior bar 1, described interior bar 1 can be driven to rotate about the axis when rotating described interior bar 2 82, make described outer bar 2 72 can do axial rectilinear movement by relatively described outer bar 1.The upper end outer wall of described outer bar 2 72 arranges radial tapped through hole, tapped through hole is installed set bolt 721.In the lower end of described outer bar 2 72, end cap 9 is set.
Except the technical characteristic described in specification, be the known technology of those skilled in the art.
