Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
Referring to Fig. 5, Fig. 6, a kind of lightning rod Connection Block of the present utility model, comprise lightning-arrest shank 2, outer tube 4, be fixed with sleeve pipe 5 in the hole of described outer tube 4, the endoporus of sleeve pipe 5 is conical bore or polygonal pyramid hole, and the lower end correspondence of described lightning-arrest shank 2 is made cone axis or polygonal pyramid axle, pegs graft and cooperate in conical bore on cone axis or polygonal pyramid axle and the sleeve pipe 5 or polygonal pyramid hole.Wherein the polygonal pyramid axle can be 3 ribs-6 a pyramid axle, and the polygonal pyramid hole can be 3 ribs-6 pyramid hole.
The cone axis on the conical bore of described sleeve pipe 5 or polygonal pyramid hole and the lightning-arrest shank 2 or the tapering of polygonal pyramid axle are 1: 300-1: 200.
The ratio of the outside diameter in conical bore or polygonal pyramid hole is 3 on the length of described sleeve pipe 5 and the sleeve pipe 5: 1-5: 1.With the reliability that guarantees that sleeve pipe 5 cooperates with lightning-arrest shank 2.
One end of described sleeve pipe 5 is fixed with a step pipe, and the external diameter of step pipe equals the external diameter of outer tube 4, and the end face of step pipe and outer tube 4 one ends is integrally welded.
The cone axis of described lightning-arrest shank 2 lower ends or the outer surface of polygonal pyramid axle are provided with annular groove 7, and corresponding annular groove 7 is provided with screw 6 on described outer tube 4 and the sleeve pipe 5, is combined with screw in the screw 6.Screw passes the screw 6 on outer tube 4 and the sleeve pipe 5, and its end is stuck in the annular groove 7, thereby the shank 2 of will taking shelter from the thunder is axially fixed in the sleeve pipe 5.
The cone axis of described lightning-arrest shank 2 lower ends or polygonal pyramid axle are conical tube or polygonal pyramid pipe, and corresponding annular groove 7 five equilibriums are provided with 2-6 screw 6 on described outer tube 4 and the sleeve pipe 5.
Referring to Fig. 5, the lower end of the endoporus of sleeve pipe 5 and lightning-arrest shank 2 all have certain tapering, facilitate lightning-arrest shank like this and cooperate with the no gap of sleeve pipe 5, can not occur taking shelter from the thunder shank 2 because of with the excessive shaking phenomenon that produces of sleeve pipe 5 fit clearances.Outer tube 4 is fixing with the upper end step pipe welding of sleeve pipe 5, outer tube 4 and fixedlying connected of sleeve pipe 5 can increase the intensity of outer tube 4 effectively, prevent that binding site stress between outer tube 4 and the lightning-arrest shank 2 from concentrating and the phenomenon of fracture takes place, greatly improved wind resistance.The lower end of lightning-arrest shank 2 adopts conical tube or polygonal pyramid pipe as cone axis or polygonal pyramid axle, radially have annular groove 7 on its outer surface, corresponding annular groove 7 has 2 to 6 screws 6 on outer tube 4 and sleeve pipe 5, screw is installed in the screw 6 and passes outer tube 4 and the tube wall of sleeve pipe 5, the leading section of screw is snapped in the annular groove, lightning-arrest shank 2 is axially locked.Referring to Fig. 6, since the airport one away from the city, the structure member of the installation lightning rod that volume is bigger is not easy to transportation, and construction condition is simple, some airport is built on the island, the lightning rod mount pad there are higher anticorrosion and Anti-Typhoon requirement, but can not add the rolling rope owing to condition restriction.The utility model is fixed on outer tube 4 on the Connection Block 1, outer tube 4 can adopt alloy pipe or thicker steel pipe to make, and carried out antirust processing in advance, the cone axis of sleeve pipe 5 inwalls and lightning-arrest shank 2 lower ends or polygonal pyramid axle are taper fit, its tapering is 1: 300-1: 200, and make lightning-arrest shank 2 to insert, and guarantee seamless connectivity, can effectively prevent lightning-arrest shank 2 install after rocking by a relatively large margin, improved reliability.
Using method of the present utility model is as follows: earlier support 1 is fixed on the position that need lay lightning rod, with the sleeve pipe 5 and fixing of packing on the outer tube 4, then outer tube 4 is weldingly fixed on the support 1, shank 2 correspondences of will taking shelter from the thunder again are inserted in the sleeve pipe 5, at last with the corresponding screw 6 that screws on outer tube 4 outer surfaces of screw, and the leading section that makes screw snaps in the annular groove 7 on the lightning-arrest shank 2, the shank 2 of so just will taking shelter from the thunder is fixing, to prevent that lightning rod bar 2 from skidding off or break away from sleeve pipe 5, so just finished lightning-arrest shank 2 installing and fixing on support 1, quick for installation, fixing reliable.
