[0036] Reference Figures 1-5 This embodiment provides a socket elbow for a cable tray, including a bearing device and a protective device 2;

[0037] The protective device 2 includes a enclosure assembly 20, which includes a first side plate 201 and a second side plate 202 disposed opposite to each other. The first side plate 201 and the second side plate 202 together form an accommodating space with two ports. The first side plate 201 is provided with a first bent edge 203 that bends toward the second side plate 202, and the second side plate 202 is provided with a second bent edge 204 that bends toward the first side plate 201.

[0038] The bearing device includes a plurality of spaced bearing rods 3. The ends of the bearing rods 3 are connected between the first side plate 201 and the second side plate 202, and the bottom of one end of the bearing rod 3 is connected to the first bent edge 203, and the bottom of the other end of the bearing rod 3 is connected to the second bent edge 204.

[0039] In the above embodiment, the socket elbow of the cable tray includes a bearing device and a protective device 2. The enclosure component 20 in the protective device 2 is a side protection structure of the socket elbow. The enclosure component 20 includes a first side plate 201 and a second side plate 202. The first side plate 201 and the second side plate 202 are arranged opposite to each other, so that the first side plate 201 and the second side plate 202 enclose a receiving space with two ports. The first bending edge 203 on the first side plate 201 bends toward the second side plate 202, and the second bending edge 204 on the second side plate 202 bends toward the first side plate 202. The side plate 201 is bent so that the first bent edge 203 and the second bent edge 204 form a support platform with a certain width. The bearing device includes a bearing rod 3. Multiple bearing rods 3 are arranged at intervals. Their two ends are respectively connected to the first side plate 201 and the second side plate 202 (such as by welding). The bottom of the bearing rod 3 is connected to the first bent edge 203 and the second bent edge 204. When the end of the bearing rod 3 is connected to the bent edge, only part of it is connected to the bent edge, and the middle part is suspended. That is, the socket elbow is a trapezoidal structure through multiple spaced bearing rods. Therefore, the first bend 203 and the second bend 204 provide bottom support for the load-bearing rod 3, so that when the cable tray system is subjected to various forces (such as its own weight, vibration, thermal expansion and contraction stress and external accidental collisions, etc.), the stress is no longer concentrated only at the connection between the end of the load-bearing rod 3 and the side plate plane. At the same time, the bend, as the bottom support of the load-bearing rod 3, increases the vertical support force of the structure and reduces the risk of the connection part breaking due to long-term high load, thereby ensuring the structural stability of the cable tray system.

[0040] Reference Figures 1-6In one embodiment, the protective device 2 further includes a socket assembly 21 disposed at the port of the receiving space. The socket assembly 21 includes a socket body 210 and a socket bending portion 211. The socket bending portion 211 is connected to the enclosure assembly 20. The socket body 210 is connected to the end of the socket bending portion 211 away from the enclosure assembly 20. The socket bending portion 211 is bent outward from the receiving space or bent inward from the receiving space.

[0041] In the above embodiments, the protective device 2 further includes a socket assembly 21 for connecting the cable tray at the receiving space port. The socket assembly 21 includes a socket body 210 and a socket bending portion 211. The socket body 210 is the main part of the socket assembly 21 that connects to the outside. The socket bending portion 211 is responsible for connecting the socket body 210 and the enclosure assembly 20. The socket bending portion 211 is closely connected to the enclosure assembly 20 and is located at the port edge of the side plate assembly. The socket body 210 is located at the end of the socket bending portion 211 away from the side plate assembly, and the two form an integral structure. 211 has two bending methods: the socket bending part 211 bends towards the enclosure assembly 20 away from the receiving space, causing the socket assembly 21 to bend outward to form an flared opening; the socket bending part 211 bends towards the enclosure assembly 20 towards the receiving space, causing the socket assembly 21 to bend inward to form a constricted opening. When there is no connecting piece 212 connecting the socket body 210, it is in an open state. A socket assembly 21 is provided at the end of each side plate, and the two socket assemblies 21 at both ends of the opening are symmetrically arranged. The socket assembly 21 improves the versatility of the three-way cable tray socket connection device and increases the connection speed.

[0042] Reference Figures 1-3 In one embodiment, the socket assembly 21 further includes a connecting piece 212, which is connected to the enclosure assembly 20 and is arranged perpendicularly to the socket body 210. The connecting piece 212 is connected to the socket body 210, or a specified distance is formed between the connecting piece 212 and the socket body 210.

[0043] In the above embodiment, the socket assembly 21 further includes a connecting piece 212, which is connected to the enclosure assembly 20 and is located at the bottom of the side panel. One side of the connecting piece 212 is connected to the first bending edge 203 and the second bending edge 204. The connecting piece 212 cooperates with the socket body 210 located on the side of the side panel, so that the connecting piece 212 and the socket body 210 are arranged perpendicularly to each other in space. There are two connection states between the connecting piece 212 and the socket body 210. When the connecting piece 212 is directly connected to the socket body 210, the socket assembly 21 forms a closed structure. When a specified distance is formed between the connecting piece 212 and the socket body 210, the socket assembly 21 forms a semi-open state. The different connection structures of the connecting piece 212 and the socket body 210 can effectively improve the speed of the three-way cable tray socket connection device connecting the cable tray, so that the socket assembly can be quickly connected to the cable tray.

[0044] Reference Figures 1-5 In one embodiment, the first side plate 201 is further provided with a third bending edge 207 corresponding to the first bending edge 203, and the second side plate 202 is further provided with a fourth bending edge 208 corresponding to the second bending edge 204. The first bending edge 203 and the third bending edge 207 are respectively perpendicular to the first side plate 201, and the second bending edge 204 and the third bending edge 207 are respectively perpendicular to the second side plate 202.

[0045] In the above embodiment, the first bending edge 203 on the first side plate 201 bends toward the second side plate 202, and the corresponding third bending edge 207 is also located on the first side plate 201, and both bending edges are perpendicular to the first side plate 201; the second bending edge 204 on the second side plate 202 bends toward the first side plate 201, and the corresponding fourth bending edge 208 is also perpendicular to the second side plate 202. The first bending edge 203, the third bending edge 207 and the first side plate 201 form a U-shaped structure, and the second bending edge 204, the fourth bending edge 208 and the second side plate 202 form a U-shaped structure. At the same time, these bending edges and the side plates are integral parts, making the structure more robust and reliable, and effectively enhancing the side plate's ability to resist external deformation.

[0046] Reference Figures 1-6 In one embodiment, the first side panel 201 is composed of three first baffles 205 connected in sequence, with a first bending angle formed between adjacent first baffles 205. The second side panel 202 is composed of two second baffles 206 connected, with a second bending angle formed between the two second baffles 206, and the angle of the first bending angle is greater than the angle of the second bending angle.

[0047] In the above embodiments, the bending angle of the enclosure component 20 is any one of 90 degrees, 45 degrees, or 22.5 degrees. When the enclosure component 20 is bent, the first side plate 201 is composed of three first enclosure plates 205, which are connected in sequence to form the bent shape of the first side plate 201, and a first bending angle is formed between adjacent first enclosure plates 205. The second side plate 202 is composed of two second enclosure plates 206, and a second bending angle is formed between the two second enclosure plates 206. The angle of the first bending angle is greater than the angle of the second bending angle, that is, the included angle between adjacent first enclosure plates 205 is greater than the included angle between adjacent second enclosure plates 206. The first side plate 201 is located on the inner side, and the second side plate 202 is located on the outer side, so that the bending length of the first side plate 201 is less than the bending length of the second side plate 202. The three first baffles 205 of the first side panel 201 form a large-angle bend, while the two second baffles 206 of the second side panel 202 form a small-angle bend. The bending angle of the enclosure assembly 20 mainly applies to the second side panel 202, that is, the bending angle of the enclosure assembly 20 is also the bending angle of the second side panel 202. As the included angle between the second baffles 206 gradually decreases, the included angle between the first baffles 205 will increase accordingly. When the included angle between the second baffles 206 becomes small enough, the first baffles 205 will gradually transition to an arc shape. This allows the entire enclosure assembly 20 to better cooperate with the surrounding cable tray components under different combinations of angles and arcs, enabling the cables to turn smoothly within a limited space, effectively utilizing space, and avoiding conflicts with other obstacles.

[0048] Reference Figures 1-4 In one embodiment, the support rod 3 includes a first support rod 30, a second support rod 31, a third support rod 32, and a fourth support rod 33. A first interval 34 is formed between the first support rod 30 and the second support rod 31, a second interval 35 is formed between the third support rod 32 and the fourth support rod 33, and a third interval 36 is formed between the second support rod 31 and the third support rod 32. The second support rod 31 and the third support rod 32 are parallel to each other. The distance between the first interval 34 and the second interval 35 gradually increases from the first side plate 201 to the second side plate 202, and the distance between the third interval 36 is initially equal and then gradually decreases from the first side plate 201 to the second side plate 202.

[0049] In the above embodiment, the support rod 3 includes a first support rod 30, a second support rod 31, a third support rod 32, and a fourth support rod 33. Their two ends are respectively connected to the first side plate 201 and the second side plate 202. The space between the first support rod 30 and the second support rod 31 forms a first interval 34, and the area between the third support rod 32 and the fourth support rod 33 is a second interval 35. The width of these two intervals gradually widens from near the first side plate 201 towards the second side plate 202. The space between the second support rod 31 and the third support rod 32 is a third interval 36. Furthermore, the second support rod 31 and the third support rod 32 are parallel to each other. The ends of the second side plate 202 connected to the third support rod 32 are cut into bevels, increasing the area of ​​the second support rod 31 and the third support rod 32 connected to the second side plate 202. This ensures that the third interval 36 maintains a uniform width and a rectangular shape for most of the length of the second support rod 31 and the third support rod 32. When it approaches the second side plate 202, its width gradually decreases, forming a triangle. The relative arrangement of the first support rod 30, the second support rod 31, the third support rod 32 and the fourth support rod 33 enhances the stability of the cable in the socket bend, reduces the possibility of failures such as wear or short circuits caused by cable shaking, and ensures the safe and stable transmission of the cable.

[0050] Reference Figure 1 , Figure 5 In one embodiment, the first side plate 201 and the second side plate 202 are respectively composed of an arc-shaped plate and two straight plates. The two straight plates are arranged on both sides of the arc-shaped plate, and a fourth interval 37 is formed between adjacent bearing rods 3. The spacing of the fourth interval 37 gradually increases from the first side plate 201 to the second side plate 202.

[0051] In the above embodiments, the bending angle of the enclosure assembly 20 is any one of 90 degrees, 45 degrees, or 22.5 degrees. The first side plate 201 and the second side plate 202 are respectively composed of an arc-shaped plate and two straight plates. The two straight plates are arranged on both sides of the arc-shaped plate. The center of the arc-shaped plate of the first side plate 201 and the center of the arc-shaped plate of the second side plate 202 are the same center. The whole structure presents an arc-shaped bending shape, which is used to provide lateral protection and guidance for cables. The space between adjacent support rods 3 forms a fourth interval 37. The support rods 3 follow the arc shape. The arcs are arranged sequentially at intervals. The first side plate 201 is located on the inner side, and the second side plate 202 is located on the outer side. Extending from the first side plate 201 to the second side plate 202, the fourth interval 37 presents a fan shape due to the change in the spacing of the bearing rods 3. The spacing is smaller near the first side plate 201 and gradually increases near the second side plate 202. This change is adapted to the arc of the arc enclosure component 20, and together they form an integral structure, providing stable support and orderly placement space for the cable at the arc bend, and ensuring the stability of the entire device.

[0052] Reference Figures 1-7 In one embodiment, the support rod 3 includes a first support plate 39, a second support plate 40, and a third support plate 41. The second support plate 40 and the third support plate 41 are vertically connected to both sides of the first support plate 39. The second support plate 40 and the third support plate 41 are parallel to each other, and the first support plate 39, the second support plate 40, and the third support plate 41 are integral parts.

[0053] In the above embodiments, in the bent or arc-shaped enclosure assembly 20, each bearing rod 3 has the same structure. The bearing rod 3 includes a first bearing plate 39, a second bearing plate 40, and a third bearing plate 41. The second bearing plate 40 and the third bearing plate 41 are vertically connected to both sides of the first bearing plate 39, and the bottoms of the second bearing plate 40 and the third bearing plate 41 are connected to the first bent edge 203 and the second bent edge 204. The first bearing plate 39 is connected to the top of the second bearing plate 40 and the third bearing plate 41, while the second bearing plate 40 and the third bearing plate 41... Parallel to each other, the first bearing plate 39, the second bearing plate 40, and the third bearing plate 41 together form a U-shaped structure. The first bearing plate 39 is used to bear the weight from above, such as for placing cables, while the second bearing plate 40 and the third bearing plate 41 provide lateral support to prevent the load from shifting in the horizontal direction, ensuring the stability and safety of the bearing rod 3. In addition, the first bearing plate 39, the second bearing plate 40, and the third bearing plate 41 are integrated into one piece, eliminating any weak points that may exist at the connection points and greatly enhancing the overall strength and rigidity of the bearing rod.

[0054] Reference Figures 1-7In one embodiment, the first support plate 39 is provided with a plurality of spaced racetrack-shaped weight reduction holes 38, and the long side of the weight reduction holes 38 extends along the length direction of the support rod 3.

[0055] In the above embodiment, the weight-reducing holes 38 are distributed on the first bearing plate 39, and their shape is preferably racetrack-shaped, with two long sides and two short sides. The long sides of the weight-reducing holes 38 extend along the length direction of the bearing rod 3, which means that they are parallel to the longitudinal axis of the bearing rod 3, so that the two long sides of the weight-reducing holes 38 are parallel to the long side of the bearing rod 3. Multiple racetrack-shaped weight-reducing holes 38 are arranged at equal intervals. The setting of the weight-reducing holes 38 effectively reduces the weight of the bearing rod 3 without affecting the basic strength of the bearing rod 3, reduces the self-weight of the entire system, and facilitates installation and transportation.
