Technical Field
[0001] The utility model relates to the technical field of cable trays, in particular to a cable tray. Background Art
[0002] When installing cable trays in buildings, problems such as later maintenance and repair need to be considered; usually, the cable trays are set with upper and lower iron plates that are closed. During maintenance and repair, the upper cover needs to be removed and placed beside, and then operations such as inspection, inspection, replacement, and maintenance of the internal cables are carried out. In some scenarios, the cables are installed at high places, and it is inconvenient to remove and place the upper cover, which affects the maintenance work efficiency. When using a circular cable tray, since the opening of the circular cable tray is small, it is not easy to take out and put in the cables during maintenance, inspection, and replacement, which affects the work efficiency. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is, in view of the above-mentioned technical deficiencies, to provide a cable tray, which adopts an inner plate rotatably arranged inside a base pipe. When the cable tray is opened, the inner plate can be rotated to open and close, avoiding the problem that when the cable tray with upper and lower covers is opened, the upper plate needs to be placed, and for the cable tray installed at a high place, it is not convenient to place the upper plate; by adopting a screw-out body arranged inside the inner plate, when the cable tray is rotated and opened, the screw-out body with a gradually increasing thickness gradually rotates downward during the process of the inner plate being rotated and opened, and the thicker part gradually falls to the bottom of the base pipe, realizing the support of the cables in the base pipe from the bottom, and solving the problem that it is inconvenient for inspection and the like due to the small opening of the circular cable tray.
[0004] To solve the above technical problems, the technical solution adopted by the utility model is: including a base pipe; and an inner plate slidably arranged inside the base pipe; the base pipe is a hollow cylindrical shape; an opening for opening and closing is axially penetrated through one side of the base pipe; a receiving cavity for receiving the inner plate is arranged inside the side wall of the base pipe at the opening; a part of the inner plate is arranged inside the receiving cavity, and a bolt hole structure for fixing is arranged on the side of the base pipe corresponding to the inner plate; a screw-out body protruding from the inner wall is arranged on the inner wall of the inner plate.
[0005] Further optimizing the technical solution, the rebounding mechanism includes a first fixing member arranged on the outer wall of the base pipe; a second fixing member arranged on the outer wall of the inner plate; a fixing bolt is penetrated through the first fixing member and the second fixing member.
[0006] Further optimizing the technical solution, two first fixing members are symmetrically arranged on both axial sides of the base pipe; two second fixing members are symmetrically arranged on both axial sides of the outer wall of the inner plate.
[0007] Further optimizing the technical solution, a smooth surface is arranged on the inner side of the screw-out body; the screw-out body is arranged with a gradually increasing thickness along the direction of the inner plate rotating and closing.
[0008] To further optimize this technical solution, a notch for enabling the rotating body to rotate is provided along the circumferential direction of the inner wall of the base tube.
[0009] To further optimize this technical solution, two rotating bodies are arranged at equal intervals along the axial direction; the middle part of the rotating body is hollow.
[0010] Compared with the prior art, the utility model has the following advantages: 1. The inner plate that can be rotated and is disposed inside the base tube is provided. This structure effectively ensures that when the cable tray is opened, the rotation and opening of the inner plate can be achieved; 2. The rotating body disposed inside the inner plate. This structure effectively ensures that after the cable tray is rotated and opened, the rotating body with a gradually increasing thickness gradually rotates downward during the process of the inner plate being rotated open, and the thicker position gradually falls to the bottom inside the base tube, realizing the bottom support for the cables inside the base tube.

[0016] To better understand the purpose, structure and function of the utility model, the following further describes in detail a cable tray of the utility model with reference to the drawings.
[0017] As Figures 1-4As shown in the figure, the utility model relates to a cable tray, which comprises a base pipe 1; and an inner plate 2 slidably arranged in the base pipe 1; the base pipe 1 is a hollow cylinder; an opening 3 for opening and closing is axially arranged through the base pipe 1 on one side of the base pipe 1; a receiving cavity 4 for receiving the inner plate 2 is arranged in the side wall on one side of the opening 3 of the base pipe 1; a part of the inner plate 2 is arranged in the receiving cavity 4, and a bolt hole structure for fixing is arranged on the corresponding side of the base pipe 1 and the inner plate 2; the bolt hole structure comprises a first fixing member 6 arranged on the outer wall of the base pipe 1; a second fixing member 7 arranged on the outer wall of the inner plate 2; a fixing bolt 8 is arranged through the first fixing member 6 and the second fixing member 7; two first fixing members 6 are symmetrically arranged on both axial sides of the base pipe 1; two second fixing members 7 are symmetrically arranged on both axial sides of the outer wall of the inner plate 2; a screwing-out body 5 protruding from the inner wall is arranged on the inner wall of the inner plate 2, and a smooth surface is arranged on the inner side of the screwing-out body 5; the screwing-out body 5 is arranged with the thickness gradually increasing along the rotation closing direction of the inner plate 2, and a notch 9 for enabling the screwing-out body 5 to rotate is arranged on the inner wall of the base pipe 1 along the circumferential direction of the screwing-out body 5; two screwing-out bodies 5 are arranged at equal intervals along the axis; the middle part of the screwing-out body 5 is hollow.
[0018] When laying cables, as Figures 1-4 shown, by removing the fixing bolts 8 used to fix the base pipe 1 to the inner plate 2 in the base pipe 1 and the adjacent base pipe 1 and its inner plate 2 on both sides of the base pipe 1, the fixing of the inner plate 2 is cancelled, and the inner plate 2 is rotated downward along the receiving groove. After unscrewing, at this time, the thicker position of the screwing-out body 5 is located at the inner bottom of the base pipe 1, realizing the supporting function. The cables are laid into the base pipe 1, and then the inner plate 2 is rotated upward to close, and then the cables can fall into the base pipe 1, and then the base pipe 1 and the inner plate 2 are fixed by the fixing bolts 8.
[0019] When inspecting the cables, as Figures 1-4 shown, after removing the fixing bolts 8, the inner plate 2 is rotated to open. During the rotation process, the cables inside the base pipe 1 are gradually pushed to the upper side along the gradually thickening screwing-out body 5, which is convenient for inspecting the cable wires. Moreover, the thickness of the screwing-out body 5 changes smoothly, avoiding the problem that the screwing-out body 5 with too large thickness change squeezes the cable wires. After the screwing-out body 5 ejects the cables, the cables in the circular cable tray with a small opening 3 can be quickly inspected. After screwing back, it ensures that the internal space of the cable tray is large enough to arrange the cable wires.
