[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1: As Figures 1 to 5 As shown, this utility model provides a cable tray, including a cable tray 1 and a cover plate 2. The cable tray 1 and the cover plate 2 are both U-shaped. During assembly, the cover plate 2 is installed on the cable tray 1. Since there are sliding strips 21 fixedly connected to the lower part of the vertically opposite surfaces of the cover plate 2, and sliding grooves 11 are provided on the front and rear sides of the upper part of the vertical outer surface of the cable tray 1, the operator only needs to align the sliding strips 21 on the cover plate 2 with the sliding grooves 11 on the cable tray 1, and then push the cover plate 2 so that the front and rear sliding strips 21 slide inside the sliding grooves 11 respectively, thus completing the sliding connection between the cover plate 2 and the cable tray 1.

[0028] Several fixing blocks 4 are fixedly connected to the bottom of the cable tray 1. When installing the cable tray 1, the mounting holes on the front and rear of the upper surface of the fixing blocks 4 can be used to fix the cable tray 1 in the corresponding installation position with bolts or other fasteners. At the same time, several heat dissipation vents 5 are provided at the bottom of the cable tray 1. These heat dissipation vents 5 help to dissipate the heat generated by the cables inside the cable tray 1, ensuring the normal operation of the cables.

[0029] Example 2: Figures 1 to 5 As shown, the cable tray 1 has several connecting components 6 inside, each including two plates 61. The rear side of the upper plate 61 is movably connected to the interior of the cable tray 1. A rotating shaft extends through the rear side of the upper plate 61, and connecting blocks are fixed to the left and right sides of the outer surface of the rotating shaft. The connecting blocks are welded to the inner wall of the cable tray 1. This structure allows the upper plate 61 to be flipped open, facilitating the laying of cables on the lower plate 61. After the cables are laid on the lower plate 61, the upper plate 61 is rotated to contact and limit contact with the blocking strip 65, facilitating the laying of cables on the upper plate 61. The outer surface of the lower plate 61 is fixedly connected to the bottom of the inner wall of the cable tray 1. The upper and lower plates 61 have the same structure, and their upper surfaces are each provided with several placement slots 62 for placing cables. Each placement slot 62 has an installation slot 63 on its lower inner wall, and rollers 64 are movably connected to the front and rear sides of the installation slot 63. When the cable is placed in the placement groove 62, if it is necessary to pull the cable during laying, the cable can contact the roller 64. The rolling of the roller 64 reduces the friction when the cable moves, making the operation easier. In addition, a stop bar 65 is provided on the front side of the lower surface of the upper plate 61. The outer surface of the stop bar 65 is fixedly connected to the inner wall of the cable tray 1. The stop bar 65 can play a certain limiting role, so that the upper plate 61 is in a horizontal state.

[0030] Example 3: Figures 1 to 5As shown, several mounting components 3 are provided on both the front and rear sides of the cable tray 1 and the cover plate 2 to connect and fix the cable tray 1 and the cover plate 2. Each mounting component 3 includes a mounting block 31 and a square block 32. The outer surface of the mounting block 31 is fixedly connected to the surface of the cover plate 2, and the outer surface of the square block 32 is fixedly connected to the surface of the cable tray 1. A T-shaped groove 33 is provided on the front side of the mounting block 31. A T-shaped block is slidably connected inside the T-shaped groove 33, allowing for up-and-down sliding. In addition, the outer surface of the T-shaped block and the inside of the T-shaped groove 33 have a magnetic attraction feature. When the T-shaped block moves upward inside the T-shaped groove 33, it will not fall downward, facilitating the pushing and installation of the cover plate 2. A U-shaped block 34 is fixedly connected to the outer surface of the T-shaped block. A groove 35 is provided in the middle of the vertically opposite surfaces of the U-shaped block 34. A U-shaped block 36 is fixedly connected to the rear side of the U-shaped block 34. Meanwhile, a plastic block 37 is fixedly connected to the front of the block 32. A V-shaped opening is provided on the upper front of the plastic block 37, and limit blocks 38 are fixedly connected to the upper left and right sides of the plastic block 37. Then, the inner side of the U-shaped block 34 is inserted into the outer surface of the plastic block 37. At this time, the inside of the groove 35 and the outer surface of the limit block 38 cooperate with each other to achieve initial positioning and connection. At the same time, the inner side of the U-shaped block 36 is inserted into the outer surface of the block 32 to further enhance the stability of the connection, thereby completing the installation and fixation between the cable tray 1 and the cover plate 2. In addition, while inserting the U-shaped block 34 into the plastic block 37, it also squeezes the plastic block 37 from left and right. The plastic block 37 has a certain deformation and bending ability, which causes the V-shaped opening to deform. When the U-shaped block 34 is inserted into the appropriate position, the plastic block 37 returns to its original position, so that the limit block 38 is just inserted into the inside of the groove 35. Conversely, if the U-shaped block 34 is moved upward with force, the V-shaped opening in the plastic block 37 will deform again, thereby removing it.

[0031] Working principle: The placement grooves 62 in the upper and lower plates 61 ensure that the cables are neatly arranged during laying, with certain gaps between the cables to allow for heat dissipation. The rollers 64 allow the cables to slide smoothly when being laid, providing flexibility during movement. After the cables are laid, the cover plate 2 is pushed to make the slide bar 21 slide inside the slide groove 11. When it slides to the appropriate position, the U-shaped block 34 moves downward, driving the U-shaped block 36 to lock the surface of the square block 32, preventing left and right movement. The limiting block 38 in the plastic block 37 locks the groove 35, preventing the U-shaped block 34 from easily sliding, thus achieving rapid installation of the cover plate 2.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
