[0006] Furthermore, the limiting assembly also includes a sleeve and a cover. The sleeve is fixedly connected to the rotating plate and is fitted over the positioning screw. The cover is threadedly connected to the sleeve.

[0007] Furthermore, both the connecting plate and the rotating plate are annular; the cable bracket is fixedly connected to the side of the rotating plate.

[0021] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Example 1

[0022] Reference Figures 1-3 An angle-adjustable power transmission device is provided, which is fixedly installed on one side of a utility pole 1. A cable bracket 5 has insulators 6 for supporting cables, and the insulators are provided with cable grooves 63. The cable bracket 5 is fixedly connected to a first rotating plate 4, which can rotate relative to the utility pole 1 to adjust the cable arrangement angle and adapt to the installation requirements of different cable transmission angles. In this embodiment, the cable bracket 5 is used for installation on the side of the utility pole 1 to meet the side installation requirements of cable lines.

[0023] The clamp 2 is composed of two metal semi-rings. The ends of the metal semi-rings are provided with first connecting through holes. The two semi-rings are tightened by first bolts 21, allowing the clamp 2 to wrap around and clamp the utility pole 1, thus achieving the fixed installation of this power transmission device on the utility pole 1. The top of the clamp 2 is provided with multiple threaded holes 22, arranged in a ring around the top of the clamp 2. To maintain the structural strength of the clamp 2, the top of the clamp 2 needs to have a certain thickness. A first connecting plate 3 is fixedly connected to the clamp 2. In this embodiment, the first connecting plate 3 is annular. To facilitate the fitting of the first connecting plate 3 onto the utility pole 1, the first connecting plate 3 is composed of two first semi-ring plates. A second connecting through hole is provided on the first semi-ring plate, the position of which corresponds to the position of the threaded hole 22 on the clamp 2. Figure 3 The first semi-ring plate is fixedly connected to the clamp 2 by the second bolt 31, and the two first semi-ring plates form a ring-shaped first connecting plate 3 at the top of the clamp 2.

[0024] refer to Figure 3 and Figure 4The first connecting plate 3 is provided with a slide rail 33. The annular slide rail 33 is formed by combining the semi-annular grooves on the first semi-annular plate. The two semi-annular grooves on the first semi-annular plate form an annular slide rail 33. The slide rail 33 is coaxially arranged with the first connecting plate 3. Each semi-annular groove is equipped with a slider 34. The two sliders 34 can move inside the annular slide rail 33.

[0025] A first rotating plate 4 is provided above the first connecting plate 3. The first rotating plate 4 is composed of two second semi-ring plates. The second semi-ring plates are fixedly connected to the slider 34 by a third bolt 41. The second semi-ring plates form an annular first rotating plate 4 above the first connecting plate 3. The first rotating plate 4 can rotate relative to the first connecting plate 3.

[0026] A cable bracket 5 is mounted on the first rotating plate 4, and the cable bracket 5 is fixedly connected to the first rotating plate 4 via a connecting rod 10. Multiple insulators 6 are provided on the cable bracket 5. Each insulator 6 is a post insulator, and a connecting screw 61 is fixedly installed at its end. The connecting screw 61 passes through the cable bracket 5, and the insulator 6 is fixedly installed on the cable bracket 5 by means of a nut 62. A wire groove 63 is provided on the insulator 6 for installing cables. The first rotating plate 4 rotates relative to the first connecting plate 3, which adjusts the position of the cable bracket 5 on the utility pole 1, thereby adjusting the cable arrangement direction.

[0027] In this embodiment, a limit component 7 is provided on the first rotating plate 4, for reference. Figure 3 The limiting component 7 includes a positioning screw 71, which is threadedly connected to the first rotating plate 4. The axis of the positioning screw 71 is parallel to the axis of the first connecting plate 3. The first connecting plate 3 has multiple first positioning holes 32, which are evenly distributed around the first connecting plate 3. The position of the positioning screw 71 corresponds to the position of the first positioning hole 32. The lower end of the positioning screw 71 can enter the first positioning hole 32, limiting the rotational displacement of the first rotating plate 4 on the first connecting plate 3. When the first rotating plate 4 needs to rotate relative to the first connecting plate 3, the positioning screw 71 is turned so that the lower end of the positioning screw 71 leaves the first positioning hole 32 on the first connecting plate 3, allowing the first rotating plate 4 to rotate relative to the first connecting plate 3 and adjust the cable arrangement direction.

[0028] To facilitate the turning of the positioning screw 71, a handle can be provided at the upper end of the positioning screw 71. To protect the positioning screw 71, in this embodiment, the limiting assembly 7 further includes a sleeve 72 and a cover 73. The sleeve 72 is fixedly welded to the first rotating plate 4, and the cover 73 is fitted over the sleeve 72 and threadedly connected to it. The sleeve 72 covers the positioning screw 71, and the cover 73 can cover the positioning screw 71, thus shielding it. The positioning screw 71 is not exposed to the outside, reducing the corrosion and damage caused by the external environment. Example 2

[0029] refer to Figures 5-6 An angle-adjustable power transmission device is provided, which can be installed on the top of the utility pole 1. The clamp 2 is composed of two metal semi-rings, and the ends of the metal semi-rings are provided with first connecting through holes. The two semi-rings are tightened by the first bolt 21, so that the clamp 2 can wrap around and clamp the utility pole 1, thereby realizing the fixed installation of the power transmission device on the top of the utility pole 1.

[0030] In this power transmission device, the top of the clamp 2 is provided with multiple threaded holes 22, and a second connecting plate 8 is fixedly connected to the clamp 2. In this embodiment, the second connecting plate 8 is a circular plate, and the second connecting plate 8 is fixedly connected to the clamp 2 by a fourth bolt 81. The top surface of the second connecting plate 8 is provided with an annular protrusion 9 and a support rod 12. The support rod 12 and the annular protrusion 9 are respectively coaxially arranged with the second connecting plate 8, and the support rod 12 is located inside the annular protrusion 9.

[0031] The aforementioned support rod 12 is rotatably connected to the second connecting plate 8, and a cable bracket 5 is fixedly installed on the top of the support rod 12. Multiple insulators 6 are provided on the cable bracket 5, and cables can be installed on the insulators 6. The support rod 12 can be rotated relative to the second connecting plate 8 to adjust the position of the cable bracket 5 on the utility pole 1, thereby adjusting the cable arrangement direction.

[0032] In this embodiment, a ring-shaped second rotating plate 11 is fixedly sleeved on the outside of the support rod 12, and a limit assembly 7 is provided on the second rotating plate 11. (See reference) Figure 6 The limiting component 7 includes a positioning screw 71, which is threadedly connected to the second rotating plate 11. An annular protrusion 9 is fixedly connected to the second connecting plate 8. The second rotating plate 11 and the annular protrusion 9 are arranged opposite to each other. The axis of the positioning screw 71 is parallel to the axis of the annular protrusion 9. (Reference) Figure 7 The annular protrusion 9 has multiple second positioning holes 91 evenly distributed around it. The positioning screw 71 is positioned corresponding to the second positioning holes 91, and its lower end can enter the second positioning hole 91, restricting the rotational displacement of the second rotating plate 11 and the support rod 12 on the second connecting plate 8. When the support rod 12 needs to rotate relative to the second connecting plate 8, the positioning screw 71 is turned, causing its lower end to leave the second positioning hole 91 on the annular protrusion 9. This allows the support rod 12 to rotate relative to the second connecting plate 8, adjusting the cable arrangement direction.

[0033] To facilitate the turning of the positioning screw 71, a handle can be provided at the upper end of the positioning screw 71. To protect the positioning screw 71, in this embodiment, the limiting component 7 also includes a sleeve 72 and a cover 73, which can cover the positioning screw 71 and shield it.

[0034] In this embodiment, the edge of the second rotating plate 11 is provided with a protective sleeve that extends downwards. The protective sleeve extends to the outside of the annular protrusion 9 and blocks the second positioning hole 91 on the annular protrusion 9.

[0035] In this embodiment, the power transmission device can be installed on the utility pole 1. The insulator 6 on its cable bracket 5 supports the cable to achieve power transmission. The cable bracket 5 is fixedly connected to the support rod 12, which can rotate relative to the utility pole 1 to adjust the cable arrangement angle and adapt to the installation requirements of different cable transmission angles. This cable bracket 5 is used to install on the top of the utility pole 1 to meet the top installation requirements of the cable line.
