[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0020] See Figures 1-2 This invention illustrates a preferred embodiment of a cable laying corner device, comprising: The first corner assembly 1 has a first guide channel and a first connecting hole. The first guide channel is used for cable to pass through, and the first connecting hole is located at the first end of the first corner assembly 1 and is perpendicular to the first guide channel. The second corner assembly 2 has its first end sleeved outside the first end of the first corner assembly 1. The second corner assembly 2 has a second guide channel and a second connecting hole. The second guide channel communicates with the first guide channel and is used for cable passage. The second connecting hole is located at the first end of the second corner assembly 2 and is perpendicular to the second guide channel. The pivot component 3 passes through the second connecting hole and the first connecting hole, so that the second corner assembly 2 and the first corner assembly 1 are rotatably connected to adjust the included angle between the second corner assembly 2 and the first corner assembly 1.

[0021] This utility model discloses a cable laying corner device, comprising a first corner assembly 1, a second corner assembly 2, and a pivoting component 3 for connecting the first corner assembly 1 and the second corner assembly 2. The first corner assembly 1 has a first guide channel, and the second corner assembly 2 has a second guide channel, which connects to the first guide channel for cable laying. The first end of the second corner assembly 2 is sleeved outside the first end of the first corner assembly 1 and is rotatably connected by the pivoting component 3, allowing the angle between the second corner assembly 2 and the first corner assembly 1 to be adjustable. This ensures that the cable laying corner device can adapt to different on-site corner conditions such as acute angles, right angles, and obtuse angles, thus having a wider range of applications and being more flexible and convenient to use.

[0022] In one embodiment, both the first guide channel and the second guide channel can restrict the radial and vertical movement of the cable, thereby effectively preventing the cable from coming off the device during the laying process, resulting in high structural stability.

[0023] See Figures 1-2 In one embodiment, both the first corner assembly 1 and the second corner assembly 2 include: The first support frame 11 has a first connecting hole; At least two first pulleys 12 are provided, both ends of which are rotatably mounted on the first support frame 11. The rotation center line of the first pulley 12 is parallel to the axis of the first connecting hole. At least two first pulleys 12 are arranged at intervals along the length of the first support frame 11. The second support frame 13 is erected on the first support frame 11; and The second pulley 14 is rotatably mounted on the second support frame 13 at both ends of its axial direction, and the rotation center line of the second pulley 14 is parallel to the rotation center line of the first pulley 12. In this design, the second pulley 14 on the first corner assembly 1 and the first pulley 12 form a first guide channel; the second pulley 14 on the second corner assembly 2 and the first pulley 12 form a second guide channel. Thus, the first support frame 11 provides stable support for the first pulley 12, ensuring its reliable installation. Similarly, the second support frame 13 provides stable support for the second pulley 14, ensuring its reliable installation. Therefore, the first pulley 12 and the second pulley 14 can work together to guide the cable's rotation. Furthermore, the rolling contact method effectively prevents damage to the cable. Additionally, the combined structure of the second support frame 13 and the second pulley 14 restricts the radial and vertical movement of the cable, effectively preventing the cable from detaching from the device during installation.

[0024] See Figures 1-2 In one embodiment, the second support frame 13 is provided with an adjustment mechanism, which is used to adjust the installation height of the second pulley 14 on the second support frame 13, so that the size of both the first guide channel and the second guide channel can be adjusted, thereby adapting to cables of different specifications and models, further expanding the scope of application, and making the use more flexible and convenient.

[0025] See Figures 1-2 In one embodiment, the second support frame 13 includes: Two support frames 131 are mounted on the first support frame 11, and the two support frames 131 are spaced apart along the length of the first support frame 11; and Two support bases 132 are connected to the same end of the two support frames 131 along the width direction of the first support frame 11 via an adjustment mechanism. That is, the two support bases 132 are placed at both ends of the support frame 131 along the width direction of the first support frame 11. Each support base 132 connects the two ends of the two support frames 131 located on the same side of the width direction to form a structurally stable second support frame 13, which provides reliable rotational support at both ends of the second pulley 14 in the axial direction, ensuring the smooth operation of the second pulley 14 and the smooth guidance of the cable. The second pulley 14 is located between the two support frames 131 and the two support bases 132, and the two ends of the second pulley 14 are rotatably supported on the bases 132 respectively.

[0026] See Figures 1-2 In one embodiment, the adjusting mechanism includes: Multiple adjustment holes 1311 are provided in each support frame 131. The multiple adjustment holes 1311 are arranged at intervals along the height direction of the corresponding support frame 131. The third connecting hole is provided at both ends of the support base 132; and Fastening bolt 133 connects the corresponding third connecting hole to the corresponding adjusting hole 1311. This adjustment mechanism, by setting multiple adjusting holes 1311 arranged along the height direction on each support frame 131 and configuring third connecting holes at both ends of the support base 132, and then using fastening bolt 133 to achieve selective connection between the two, constitutes a simple, convenient, and stable multi-position adjustment module. This allows the vertical installation position of the support base 132 to be flexibly and precisely adjusted and reliably locked according to the actual outer diameter of the cable, thereby driving the second pulley 14 supported by it to synchronously change its height position, ensuring the cable's guiding effect and anti-detachment capability. Simultaneously, the connection between the adjusting hole 1311 and the third connecting hole via fastening bolt 133 also allows the second pulley 14 to be disassembled, making cable installation more convenient and reducing the difficulty of cable laying.

[0027] Of course, in other embodiments, a pin can be used instead of the fastening bolt 133.

[0028] See Figures 1-2 In one embodiment, the first corner assembly 1 is provided with three first pulleys 12 and the second corner assembly 2 is provided with two first pulleys 12. That is, the device is a multi-pulley structure, which can reduce traction resistance and thus effectively reduce the risk of mechanical damage to the cable.

[0029] In one embodiment, the outer surfaces of both the first pulley 12 and the second pulley 14 are covered with a polymer wear-resistant layer (e.g., polyurethane) to further reduce traction resistance.

[0030] In one embodiment, the rotation center line of one of the first pulleys 12 of the first corner assembly 1 is located on the side close to the first connecting hole, so as to further reduce the traction resistance and reduce the resistance of the cable acting on the first pulley 12. Thus, during the laying process, only a smaller traction force is needed to drive the second corner assembly 2 to rotate smoothly around the pivot member 3 to adjust the angle. At the same time, it can also improve the smoothness of cable passage and reduce the risk of friction or jamming.

[0031] In one embodiment, the rotation center line of one of the first pulleys 12 of the first corner assembly 1 coincides with the central axis of the first connecting hole, that is, the first pulley 12 is coaxial with the pivot component 3, so that when the device is adjusting the angle, the first pulley 12 can rotate synchronously around the same axis, which not only eliminates motion interference and additional frictional resistance that may be caused by axis offset, but also further improves the smoothness of cable guiding process and reduces wear.

[0032] See Figures 1-2 In one embodiment, the first support frame 11 includes: Two supporting side plates 111 are respectively placed on both sides of the width direction of the first supporting frame 11; and Support rod 112 is provided along the width direction of the first support frame 11 and connects two support side plates 111. The first pulley 12 is located between the two supporting side plates 111 and the supporting rod 112, with its axial ends rotatably mounted on the corresponding supporting side plates 111. The first support frame 131, through the use of two supporting side plates 111 positioned on either side of its width and the supporting rod 112 connecting them, forms a stable rigid support frame 131. This not only provides span support for the first pulley 12, ensuring its smooth operation and effective load bearing, but also significantly enhances the overall integrity and structural strength of the first support frame 11 by using the lateral connection of the supporting rod 112 to the two supporting side plates 111. This effectively resists the lateral forces generated during cable laying and achieves stable guidance and steering of the cable.

[0033] See Figures 1-2 In one embodiment, the support rod 112 on the first corner assembly 1 is located at its second end, and the support rod 112 on the second corner assembly 2 is also located at its second end, so that the support rod 112 is away from the pivot member 3, thereby preventing the support rod 112 from interfering with the rotation of the second corner assembly 2.

[0034] To improve the connection strength between the first corner assembly 1 and the second corner assembly 2, in one embodiment, each supporting side plate 111 on the first corner assembly 1 is provided with a first connecting hole at its first end, and each supporting side plate 111 on the second corner assembly 2 is provided with a second connecting hole at its first end. The second connecting hole and the first connecting hole on the same side are connected by a corresponding pivot member 3.

[0035] See Figures 1-2 In one embodiment, both the first corner assembly 1 and the second corner assembly 2 are provided with a plurality of connecting parts 4 at their bottoms. Each connecting part 4 has a fourth connecting hole, which is connected to an external support by a fixing bolt, thereby fixing the device to the external support.
