[0019] In order to make the purpose, technical scheme of the utility model clear, complete and the advantages more clear and apparent, the embodiments of the utility model are further described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the utility model, not all the embodiments, and are only used to explain the embodiments of the utility model, and do not limit the embodiments of the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] Please refer toFigures 1-6 The utility model provides a technical scheme: a kind of anti-loosening connection structure for iron accessory half-round hoop, including screw rod 1, screw rod 1 is penetrated the side plate of hoop plate 2 and the top plate of iron accessory 3, the bottom end of screw rod 1 is equipped with nut 10 with screw joint, hoop plate 2 is "U" letter-shaped plate structure, and the both ends of hoop plate 2 are integrally formed with connecting plate, and bolt hole is formed on the top plate of connecting plate and iron accessory 3, and the rod body of screw rod 1 is penetrated two bolt holes.Screw rod 1 is penetrated the bolt hole on the surface of hoop plate 2 and iron accessory 3 after, nut 10 is screwed on the rod body of screw rod 1 and is locked, at this time, hoop plate 2 is firmly fixed on the top of iron accessory 3, and hoop plate 2 is used to fix the cross arm structure on iron or other metal accessories.

[0021] The surface of screw rod 1 is fixed with elastic metal traction plate 4, the bottom end of elastic metal traction plate 4 is fixed with clamping strip 5, clamping strip 5 is inserted on the side wall of the top plate of iron accessory 3, elastic metal traction plate 4 is "L" letter-shaped plate structure, one end of elastic metal traction plate 4 is fixed on the top plate body of screw rod 1, and elastic metal traction plate 4 is equipped with two, two elastic metal traction plate 4 are symmetrically distributed about screw rod 1, the bottom surface of the top plate of elastic metal traction plate 4 is provided with embedding groove 8, rubber gasket 9 is fixed in embedding groove 8, and the thickness of rubber gasket 9 is greater than the height of embedding groove 8;Clamping strip 5 is right trapezoidal strip, and the height of clamping strip 5 is less than the height of clamping groove 6, the surface of elastic metal traction plate 4 is fixed with pull ring 7, and pull ring 7 and clamping strip 5 are symmetrically distributed about elastic metal traction plate 4.When screw rod 1 and nut 10 are screwed and locked, clamping strip 5 is inserted into clamping groove 6, the top end of screw rod 1 is pulled through elastic metal traction plate 4, avoid the hidden danger that screw rod 1 is thrown off from bolt hole when nut 10 falls off from the bottom end of screw rod 1, and elastic metal traction plate 4 extrudes rubber gasket 9 downwards, and rubber gasket 9 plays the role of elastic gasket when nut 10 and screw rod 1 are screwed and locked.

[0022] Use flow as follows:

[0023] Place the hoop plate 2 (in the shape of a "U" plate structure) on the top of the iron accessory 3, make sure that the two end connecting plates of the hoop plate 2 are aligned with the top plate of the iron accessory 3. Pass the screw rod 1 through the bolt hole on the connecting plate and the top plate of the iron accessory 3 from one side to the other side. Confirm that the elastic metal traction plate 4 (in the shape of an "L" plate structure) is correctly installed on the screw rod 1, and the two elastic metal traction plates 4 are symmetrically distributed about the screw rod 1. Check whether the rubber pad 9 is firmly embedded in the embedding groove 8 of the elastic metal traction plate 4, and make sure that the thickness of the rubber pad 9 is greater than the height of the embedding groove 8 to provide sufficient elastic support.
