[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figures 1-4 This utility model provides a protective crossarm accessory, comprising: A pair of half hoops 1 are configured to clamp together to secure them to the post 2; Top cover 3 is installed on top of a pair of half-hoops 1, and top cover 3 is threadedly connected to the pair of half-hoops 1; A pair of fixing plates 4 are respectively fixed on both sides of the half hoop 1 away from the top cover 3. The two fixing plates 4 on the same side of the pair of half hoop 1 are distributed opposite each other, and a connecting component is passed between the two fixing plates 4. The two fixing plates 4 are fixed relative to each other and have a pre-tightening force in the direction of mutual approach. Among them, the outer walls of the pair of half hoop 1 are fixed with crossbeams 5, and the two crossbeams 5 extend in directions that are far apart from each other.

[0019] This invention fixes a pair of half-hoops 1 to the column 2 by engaging them, and uses a top cover 3 to cover the top of the pair of half-hoops 1 and thread it to fix the engaged pair of half-hoops 1, thereby improving the connection stability between the pair of half-hoops 1. At the same time, fixing plates 4 are fixed to both sides of the half-hoops 1, and a connecting component is set between the two fixing plates 4 on the same side. The connecting component provides a pre-tightening force between the two fixing plates 4 to bring them closer together. Through the stable connection and fixation between the pair of half-hoops 1, the crossbeam 5 is fixedly supported. Compared with the traditional method of connecting two pairs of hoop, this patent simplifies the installation steps by using a top cover 3 threadedly covered on the top of the pair of half-hoops 1 and providing a pre-tightening force during the fixing process through the connecting component. This makes it easier for personnel to install, improves the connection stability, and achieves long-term fixation.

[0020] Furthermore, the connection components include: The support sleeve 6 has two ends that abut against two oppositely distributed fixed plates 4. A connecting bolt 7 is inserted inside the support sleeve 6, and the two ends of the connecting bolt 7 pass through the two fixed plates 4 in opposite directions. The preload is installed on the part of the connecting bolt 7 that extends out of the fixing plate 4, and the preload is detachably connected to the connecting bolt 7.

[0021] By having the two ends of the support sleeve 6 abut against the two fixed plates 4, and using pre-tightening components set on the connecting bolts 7, a pre-tightening support is formed between the connecting bolts 7 and the fixed plates 4, thus achieving a stable connection between the connecting bolts 7 and the pre-tightening components.

[0022] Furthermore, the preload includes: Support plate 8 is an arc-shaped plate with a through hole in the center. Connecting bolt 7 extends out of the fixed plate 4 and passes through the through hole. The connecting nut 9 is threaded onto the connecting bolt 7. The connecting nut 9 and the fixing plate 4 abut against the support plate 8 in opposite directions. The connecting nut 9 has a tendency to move away from the fixing plate 4.

[0023] Specifically, the connecting nut 9 is threaded onto the connecting bolt 7, and the other end of the connecting bolt 7 is snapped onto the fixing plate 4, forming a connection and fixation between the connecting bolt 7 and the connecting nut 9 and the two fixing plates 4. The bow-shaped support plate 8 provides elastic support force. As the connecting nut 9 is connected and fixed to the connecting bolt 7, the fixing plate 4 and the connecting nut 9 press against the support plate 8 in opposite directions. The elastic reset effect provided by the support plate 8 is used to achieve pre-tightening of the connecting nut 9 and the connecting bolt 7, thereby improving the fixing stability.

[0024] Furthermore, it also includes: Two positioning blocks 10 are fixedly connected to the opposite sides of any half of the hoop 1; Two guide blocks 11 are fixed on opposite sides of the other half of the hoop 1, which is away from the positioning block 10. A guide groove is provided in the middle of one side of the guide block 11, and a locking protrusion 12 is fixed in the middle of the positioning block 10. The locking protrusion 12 is embedded in the adjacent guide groove.

[0025] By fixing positioning blocks 10 to both sides of half hoop 1 and guide blocks 11 to both sides of the other half hoop 1, the guide groove in the middle of the guide block 11 guides and positions the locking protrusion 12 in the middle of the positioning block 10. By embedding the locking protrusion 12 in the guide groove, the pair of half hoop 1 can be accurately connected and the pair of half hoop 1 can be locked and fixed in the vertical direction.

[0026] Furthermore, reinforcing plates 13 are fixedly connected to both sides of the crossbeam 5 and a pair of fixed plates 4.

[0027] Furthermore, the reinforcing plate 13 is welded to the side wall of the half hoop 1, thereby increasing the connection strength between the crossbeam 5 and the half hoop 1 through the reinforcing plate 13.

[0028] Furthermore, the bottom surface of the top cover 3 is provided with a threaded groove 15, and the top of the pair of half-hoops 1 are respectively provided with threads, and the two threads are configured to engage with the threaded groove 15 for threaded connection.

[0029] The positioning block 10 and guide block 11 are used to achieve accurate positioning and docking of a pair of half-hoops 1, so that the two relatively distributed threads correspond. As the top cover 3 is placed on the top of the pair of half-hoops 1, the two threads can be threadedly connected to the thread groove 15.

[0030] Furthermore, a number of lever plates 14 are fixedly connected to the outer side wall of the top cover 3 at equal intervals in the circumferential direction.

[0031] The top cover 3 can be rotated by the lever 14 to facilitate the connection and fixation of the pair of half hoops 1.

[0032] Furthermore, several insulators 16 are arranged at intervals along the length of the top surface of the crossarm 5.

[0033] This utility model provides a working principle for a protective crossarm iron accessory: Connect the pair of half-hoops 1 together so that the locking protrusion 12 extends into the guide groove. Then, the connecting bolt 7 passes through the two fixing plates 4 and the support sleeve 6 one by one. The support plate 8 is sleeved on the end of the connecting bolt 7 that extends out of the fixing plate 4. The connecting nut 9 is threadedly connected to the connecting bolt 7 to achieve the connection and fixation of the pair of half-hoops 1. As the connecting nut 9 continues to rotate, the pair of half-hoops 1 are tightly connected and the support plate 8 is squeezed. The support plate 8 provides elastic pre-tightening force. Finally, rotate the lever 14 so that the cover plate covers the top of the pair of half-hoops 1. Rotate the cover plate to thread the top of the pair of half-hoops 1 with the threaded groove 15 to complete the fixation of the pair of half-hoops 1. Finally, tighten the connecting nut 9 again and connect and fix the cable to the insulator 16.
