[0002] Iron fittings generally refer to the iron parts on concrete poles and their connections, such as various clamps, bolts, crossbeams, crossbars, tie rods, and conductor bars. Transmission lines often use crossarm iron fittings for support and fixation. The function of the crossarm is as follows: a horizontally fixed angle iron at the top of the pole, with porcelain insulators on it, used to support overhead power lines. The crossarm is an important component of the pole tower; its function is to install insulators and hardware, support conductors and lightning protection wires, and maintain a certain safe distance as required. Crossarm iron fittings are mostly installed on the pole with bolts. Existing crossarm fittings generally use bolts to install on the pole, requiring multiple tightenings of a large number of bolts during installation, which is inconvenient for high-altitude work. Furthermore, bolts are prone to loosening or corrosion due to prolonged exposure to wind and rain, making the crossarm fittings prone to loosening. Therefore, there is an urgent need for a fastening type of crossarm iron fitting that is easy to install and provides a stable connection. Utility Model Content

[0018] 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.

[0019] 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.

[0020] Reference Figure 1-4 This utility model provides an easy-to-install fastening crossarm accessory, including a first arc-shaped plate 2 and a second arc-shaped plate 3 adapted to a utility pole 1. Both the first arc-shaped plate 2 and the second arc-shaped plate 3 are semi-circular, and one end of the first arc-shaped plate 2 and the second arc-shaped plate 3 are rotatably connected. A connecting component is provided between the first arc-shaped plate 2 and the second arc-shaped plate 3. A crossarm 4 is fixedly connected to the first arc-shaped plate 2, and several winding wheels 5 are installed on the crossarm 4. The fastening component is installed on the first arc-shaped plate 2. By rotatably connecting the first arc-shaped plate 2 and the second arc-shaped plate 3, during installation, only one end of the second arc-shaped plate 3 needs to be inserted into the first arc-shaped plate 2, and the installation can be completed through the connecting component. The installation process is simple and easy to operate. Moreover, through the engagement of the internal arc-shaped locking strip 6 and the mating locking strip 8, it is not easy to loosen, ensuring the stability of the connection between the crossarm 4 and the utility pole 1. The fastening component allows the crossarm 4 accessory of this utility model to be used on smaller utility poles 1, ensuring a stable connection between the crossarm 4 accessory and the utility pole 1.

[0021] The scheme is further optimized. The connecting component includes an arc-shaped retaining strip 6 fixedly connected to the end of the second arc-shaped plate 3. The side wall of the arc-shaped retaining strip 6 is provided with several retaining teeth. The end of the first arc-shaped plate 2 is provided with a first receiving groove 7 corresponding to the arc-shaped retaining strip 6. A mating retaining strip 8 is rotatably connected in the first receiving groove 7. A retaining block adapted to the retaining teeth is provided on the side wall of the mating retaining strip 8. Several compression springs 9 are fixedly connected between the side of the mating retaining strip 8 away from the arc-shaped retaining strip 6 and the side wall of the first receiving groove 7. A limiting block 10 is fixedly connected in the first receiving groove 7. The limiting block 10 is located on the side of the mating retaining strip 8 close to the arc-shaped retaining strip 6 and is in contact with the mating retaining strip 8. During installation, first attach the first arc plate 2 to the utility pole 1, then rotate the second arc plate 3. The second arc plate 3 drives the arc-shaped clip 6 to rotate into the first receiving groove 7. During the entry process, the clip teeth of the arc-shaped clip 6 squeeze the clip block. After the arc-shaped clip 6 has completely moved into the first receiving groove 7, it cooperates with the clip block on the clip 8 to limit the arc-shaped clip 6 and prevent it from being pushed out, thereby realizing the connection.

[0022] Furthermore, the teeth on the arc-shaped locking strip 6 are unidirectional teeth, and can only move in the direction of the first receiving groove 7 during the process of engaging with the mating locking strip 8.

[0023] A further optimized design includes a second receiving groove 11 within the second arc-shaped plate 3. The end of the mating retainer 8 is located within this groove. A cam 12 is rotatably connected within the groove 11, positioned on the side of the mating retainer 8 furthest from the compression spring 9. An adjustment knob 13 is rotatably connected to the outer side of the second arc-shaped plate 3, and is coaxially and fixedly connected to the cam 12. When disassembly is required, rotating the adjustment knob 13 rotates the cam 12, causing it to rotate and disengage the mating retainer 8 from the arc-shaped retainer 6. This allows the crossarm iron accessory to be removed for easy replacement and maintenance.

[0024] The fastening assembly is further optimized by including a groove formed in the inner wall of the first arc-shaped plate 2, with a fastening strip 14 slidably connected within the groove. A threaded rod 15 is threadedly connected to the first arc-shaped plate 2, with one end of the threaded rod 15 rotatably connected to the outer wall of the fastening strip 14, and the other end of the threaded rod 15 located on the outer side of the first arc-shaped plate 2 and fixedly connected to an adjusting nut. By adjusting the nut, the threaded rod 15 is rotated, which causes the fastening strip 14 to move towards the center of the first arc-shaped plate 2, thereby tightly fitting against the utility pole 1 and increasing the overall stability of the connection with the utility pole 1.

[0025] Furthermore, the fastening assembly can also be a series of threaded rods 15 directly threaded onto the first arc plate, with the threaded rods 15 abutting against the pole 1 to increase the stability of the connection.

[0026] In a further optimized design, two connecting plates 16 are fixedly connected between the first arc-shaped plate 2 and the crossbeam 4, and the threaded rod 15 is located between the two connecting plates 16.

[0027] A further optimized design incorporates a limit bolt 17 threaded onto the second arc-shaped plate 3. One end of the limit bolt 17 is located outside the second arc-shaped plate 3, while the other end is located within the second receiving groove 11. The end of the limit bolt 17 within the second receiving groove 11 is positioned on the side of the mating retaining strip 8 furthest from the cam 12. By positioning the bottom of the limit bolt 17 on the side of the mating retaining strip 8 furthest from the cam 12, the mating retaining strip 8 can be limited, preventing it from rotating under external vibrations and ensuring that the mating retaining strip 8 can limit the arc-shaped retaining strip 6.

[0028] The design is further optimized so that the center of the arc of the arc-shaped retaining strip 6 and the mating retaining strip 8 is concentric with the rotation center of the first arc-shaped plate 2 and the second arc-shaped plate 3. This facilitates the arc-shaped retaining strip 6 to move with the second arc-shaped plate 3 into the first receiving groove 7 to mate with the mating retaining strip 8.

[0029] The working process of this utility model is as follows: In use, the first arc-shaped plate 2 is attached to the utility pole 1, and then the second arc-shaped plate 3 is rotated. The second arc-shaped plate 3 drives the arc-shaped retaining strip 6 to move and insert into the first receiving groove 7. The retaining teeth on the arc-shaped retaining strip 6 squeeze the retaining block to facilitate the entry of the arc-shaped retaining strip 6. Then, the retaining teeth and retaining block cooperate to prevent the retaining strip 6 from retracting. If there is a gap between the utility pole 1 and the first arc-shaped plate 2 and the second arc-shaped plate 3, the threaded rod 15 is rotated. The bolt rod 15 drives the fastening strip 14 to move and abut against the utility pole 1, thereby ensuring a stable connection. To ensure the stability of the mating retaining strip 8, the limiting bolt 17 is rotated so that the bottom end of the limiting bolt 17 limits the mating retaining strip 8, preventing the mating retaining strip 8 from moving under external vibration and ensuring that the mating retaining strip 8 limits the arc-shaped retaining strip 6.
