[0002] In traditional power lines or similar structures, in order to fix and support various insulators, it is often necessary to use a hoop structure. The traditional hoop structure is usually made of metal and is in the shape of a half-circle or an "Ω". It is fixed on the support structure by fasteners such as bolts. However, in practical applications, the traditional hoop structure has some problems, especially during installation and after long-term use.

[0003] During installation, the hoop is installed on the top of the pole with the crossbar. Due to the lack of tight cooperation or lack of pre-limiting mechanism between the hoop body and the crossbar structure, the hoop body is prone to displacement or jolt before the installation of the bolt, which not only increases the difficulty of installation, but also may affect the final fixing effect. In addition, due to the influence of external factors such as vibration and wind force, the traditional hoop structure may loosen during long-term use, resulting in unstable pipe fixing, and even causing safety accidents.

[0004] In order to solve the above problems, an improved hoop structure is needed, which can provide stable pre-limiting effect during installation and enhance the anti-loose performance during long-term use. SUMMARY

[0005] The utility model aims at providing an anti-loose iron accessory half-round hoop structure to solve the problems raised in the background.

[0007] Preferably, the hoop body is in the shape of an "Ω" plate structure, and the two bottom plates of the hoop body and the surface of the crossbar are provided with bolt holes, and the two groups of bolt holes are penetrated by bolts.

[0008] Preferably, the bottom surface of the crossbar is fixed with a connecting plate, and the bottom end of the connecting plate is fixed with a mounting plate.

[0009] Preferably, the top surface of the crossbar is provided with a reserved hole, the reserved hole is provided with two groups, the two groups of reserved holes are respectively distributed around the two bolt holes, the plug rod and the reserved hole are one-to-one corresponding, the plug rod is inserted into the reserved hole, and the height of the plug rod is less than the height of the reserved hole.

[0010] Preferably, the diameter of the guide rod is smaller than the diameter of the insertion rod, the diameter of the insertion rod is equal to the diameter of the reserved hole, and the diameter of the rubber clamping ball is greater than the diameter of the reserved hole.

[0011] Preferably, the surface of the insertion rod is provided with an embedded groove, the embedded groove is an annular groove, a rubber ring is fixedly sleeved in the embedded groove, and the outer diameter of the rubber ring is greater than the diameter of the reserved hole.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] The anti-loosening iron accessory half-round hoop structure disclosed by the utility model is characterized in that the insertion rod is fixed on the surface of the hoop body, and the reserved hole is arranged on the top surface of the cross arm, so that the hoop body can be preliminarily positioned through the cooperation of the insertion rod and the reserved hole during installation. The pre-limiting mechanism greatly simplifies the installation process, reduces the displacement or jolt of the hoop body before the bolt is installed, and improves the installation efficiency and accuracy. The design of the guide rod at the bottom end of the insertion rod and the rubber clamping ball enables the rubber clamping ball to be clamped below the reserved hole after the insertion rod is inserted into the reserved hole, thereby forming an additional fixed barrier. Meanwhile, the rubber ring sleeved in the embedded groove on the surface of the insertion rod further increases the friction between the insertion rod and the reserved hole, thereby effectively preventing the loosening of the hoop body caused by external factors such as vibration and wind force during long-term use.
