[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] [First Embodiment] like Figure 1-6 The image shown is a cable restraint device inside a cable tray according to the first embodiment of this utility model. Figure 1As shown, the cable tray body 1 is included. Cables are run through the inside of the cable tray body 1. Sliding grooves are provided on both the inner and outer walls of the cable tray body 1. The cable tray body 1 is installed and fixed in a preset position to ensure that it is installed firmly and meets the load requirements of the cable system. Then, the cables are run through the inside of the cable tray body 1 and the cables are extended and arranged according to the planned route.

[0025] The improvement of this embodiment compared to the prior art lies in the following: a cable tray body 1 is provided with a cable bundling device 2. One end of the cable bundling device 2 can slide relative to the sliding groove, and the other end of the cable bundling device 2 limits and fixes the cables running through the cable tray body 1. A reinforcing component 3 is also provided in the middle of the cable bundling device 2. When using the cable tray body to install and lay cables, the cables can be effectively and stably constrained and fixed. The cables can be constrained or released as needed, making installation and removal flexible and convenient, saving time and costs associated with cable constraint, and facilitating cable inspection and maintenance. At the same time, the position of the cable bundling device can be adjusted according to the actual situation, increasing the scope of application and improving practicality.

[0026] like Figure 2-5 As shown, the cable bundling device 2 in this embodiment includes a mounting block 21 that is snapped onto one side of the cable tray body 1. A rotating shaft 22 is installed on both sides of the bottom of the mounting block 21. A roller 23 is rotatably provided on the outer edge of the rotating shaft 22. The roller 23 rolls with the sliding groove. The rolling cooperation between the roller 23 and the sliding groove can realize the cable bundling position of the cable bundling device 2 relative to the cable tray body 1, so as to adjust the cable bundling position according to the actual situation, increase the scope of application and improve practicality.

[0027] To achieve proper positioning after adjustment, the inner wall of the mounting block 21 is provided with a mounting groove 24. A fixing block 25 is slidably connected inside the mounting groove 24. A bolt 26 passes through the mounting block 21 and is threadedly connected to the fixing block 25. After the cable harness 2 is adjusted to a proper position relative to the cable tray body 1 by the rolling cooperation of the roller 23 and the sliding groove, the bolt 26 is rotated to drive the mounting block 21 to move towards each other inside the mounting groove 24 until it engages with the side walls on both sides of the cable tray body 1, thereby achieving the positioning and fixing of the cable harness 2 in the current position.

[0028] To achieve the desired cable bundling effect inside the cable tray body 1, a rotating rod 27 is rotatably connected to one end of the mounting block 21. A connecting plate 28 is fixedly connected to the outer edge of the rotating rod 27, and a pressure plate 29 is rotatably connected to the other end of the connecting plate 28. The pressure plate 29 has several evenly distributed fixing grooves 210 on the side facing the cable. The fixing grooves 210 accommodate the cables inside the cable tray body 1, thus bundling the cables. Furthermore, a reinforcing pad 216 is provided on the inner wall of the fixing groove 210. By using the rubber reinforcing pad 216, the friction between the inner wall of the fixing groove 210 and the outer edge of the cable is increased, achieving flexible contact with the cable while improving the stability of the cable bundling effect and reducing the possibility of unexpected slippage. Meanwhile, threaded posts 217 are installed on both sides of the pressure plate 29. The end of the threaded post 217 closest to the cable is rotatably connected to a suction cup 218. Through the threaded post 217 and the suction cup 218, while the pressure plate is binding the cable, the threaded post can be rotated to make the suction cup contact and adhere to the inner wall of the cable tray body, so as to further improve the stability of the cable binding.

[0029] To achieve the positioning of the current corner position, a positioning plate 211 is fixedly connected to the outer edge of the rotating rod 27 away from the connecting plate 28. A locking plate 212 is slidably connected inside the mounting block 21. The locking plate 212 and the positioning plate 211 are in a limiting cooperation. Through the limiting cooperation between the locking plate 212 and the positioning plate 211, the corner position of the rotating rod 27 and the connecting plate 28 fixed thereto relative to the mounting block 21 is limited when the cable is bundled by the pressure plate 29, thereby further improving the bundling stability at the current angle position. Based on this, one end of the clamping plate 212 is provided with an elastic element 215, and the other end of the elastic element 215 is fixedly connected to the inner wall of the mounting block 21. The elastic element 215 can be a spring or other elastic element commonly used in the mechanical field. When it is necessary to release the wire harness, the clamping plate 212 is pressed towards the elastic element 215. At this time, the limiting effect of the clamping plate 212 on the positioning plate 211 disappears. At this time, the rotating rod 27 can be controlled to rotate relative to the mounting block 21 to release the wire harness effect. When re-entering the wire harness, the elastic element 215 drives the clamping plate 212 to move towards the positioning plate 211 under its own elastic restoring force to re-enter the limiting position, thereby realizing the wire harness effect at the current position. As a further preferred option, similarly, circular plates 214 are fixedly connected to both ends of the rotating rod 27, and torsion springs 213 are respectively sleeved on the outer edges of both ends of the rotating rod 27. The two ends of the torsion springs 213 are fixedly connected to the circular plates 214 and the mounting block 21, respectively. By setting the torsion springs 213, after adjusting the wire angle, when the clamping plate 212 and the positioning plate 211 are released from the limit and re-enter the limit, the connecting rod and the rotating rod will rotate under the elastic restoring force of the torsion spring, so that the clamping plate 212 and the positioning plate 211 can re-enter the limit. Thus, the current angle position is limited by the torsion spring and the elastic element at the same time, increasing the limit stability.

[0030] like Figure 3 and Figure 6 As shown, the reinforcement component 3 in this embodiment includes a connecting rod 31 fixedly connected to the connecting plate 28. The connecting rod 31 is sleeved on the outer periphery of the wire rope 33. A threaded tube 32 is also provided between the inner wall of the connecting rod 31 and the outer wall of the wire rope 33. A washer 35 and a nut 34 are sleeved on the outer edge of the threaded tube 32. The threaded tube 32 and the nut 34 are threadedly connected to provide a moving track for adjusting the position of the wire harness 2 through the wire rope 33. This allows the wire harness 2 on both sides to adjust its position relative to the cable tray body 1 through the shared wire rope 33 in the middle. At the same time, after moving to the target position, the threaded connection of the nut 34 on the outer edge of the threaded tube 32 causes the threaded tube 32 to contract and squeeze, thereby locking the wire harness 2 in the current axial position of the wire rope 33. The adjustment is convenient.

[0031] The working process of this embodiment is as follows: When laying and installing cables inside the cable tray body 1, the cable tray body 1 is installed and fixed in a preset position. Then, the cables are passed through the inside of the cable tray body 1 and rolled in the sliding grooves on both sides of the cable tray body 1 by the rollers 23 on both sides of the mounting block 21 until the mounting block 21 is slid to the target cable bundle position. At this time, the rotating bolt 26 drives the mounting block 21 to move towards each other in the mounting groove 24 until it is engaged with the side walls on both sides of the cable tray body 1, thereby achieving the positioning and fixing of the cable bundle device 2 in the current position. While adjusting the position of the cable bundle on the mounting block 21, the wire rope 33 provides a moving track for the adjustment of the position of the cable bundle device 2, so that the cable bundle devices 2 on both sides can adjust their positions relative to the cable tray body 1 through the shared wire rope 33 in the middle. At the same time, after moving to the target position, the threaded connection of the nut 34 on the outer edge of the threaded tube 32 causes the threaded tube 32 to contract and squeeze, thereby locking the cable bundle device 2 in the current axial position of the wire rope 33, which is convenient for adjustment.

[0032] Rotate the rotating rod 27, which will drive the connecting plate 28 and the pressure plate 29 fixed thereto to rotate synchronously until the fixing groove 210 contacts the outer edge of several cables in sequence. At this time, release the locking plate 212 so that the locking plate 212 limits the positioning plate 211, so that the pressure plate 29 is fixed at the current corner position.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
