[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] Example 1 like Figure 1 and Figure 2 As shown, this utility model provides a fireproof cable tray structure, including a cable tray groove 1 and a cover plate 2. Threaded holes are correspondingly opened on the side walls of the cable tray groove 1 and the cover plate 2, and they are fixed by a first fixing bolt 4.

[0021] The cable tray trough 1 and the cover plate 2 consist of a fireproof layer 13 and a support plate layer 14, respectively, from the outside to the inside. While providing excellent support, they also offer fire protection for the internal cables. In the event of a fire among the internal cables, the fireproof layer 13 can effectively prevent the fire from spreading. The fireproof layer 13 uses a commonly used fireproof material in existing technology, such as asbestos mesh, while the support plate layer 14 is made of steel plate. The top of the cover plate 2 has ventilation holes 10, which can dissipate internal heat in a timely manner, greatly reducing the possibility of cable fires caused by excessively high internal temperatures.

[0022] like Figure 3 and Figure 4 As shown, the bottom of the cable tray trough 1 is provided with several first slots 11 that pass through both ends of the cable tray trough 1 along the cable placement direction. In this embodiment, the first slot 11 is a "T-shaped slot". A partition 9 is movably engaged in the first slot 11. The partition 9 is a corresponding "T-shaped plate", which can effectively separate the cables and prevent the cables from shifting or tangling.

[0023] The partition 9 includes a retaining plate 91 located within the first retaining groove 11 and a vertical plate 92 fixedly connected to the retaining plate 91, allowing the partition 9 to be stably engaged within the first retaining groove 11. The opening of the first retaining groove 11 must be smaller than the width of the cable to prevent the cable from getting stuck in the first retaining groove 11. During actual installation, the number and insertion position of the partitions 9 can be flexibly adjusted according to the number and type of cable to achieve the function of limiting the cable.

[0024] A threaded hole is provided at the center of the top of the cover plate 2, and a wire clamping assembly 3 is installed thereon. Figure 3 As shown, the pressure assembly 3 includes a threaded rod 32 vertically disposed in a threaded hole. A rotating rod 31 is connected to the top of the threaded rod 32. The operator can manually rotate the rotating rod 31 to drive the threaded rod 32 to move up and down in the threaded hole at the center of the cover plate 2.

[0025] A connecting bearing 33 is fixedly connected to the bottom of the threaded rod 32, and a pressure plate 34 is fixedly connected to the bottom of the connecting bearing 33. Limit blocks 35 are provided at both ends of the pressure plate 34. Figure 5 As shown, second slots 12 are provided on the left and right sides of the middle part of the cable tray trough 1, such as... Figure 4 As shown, the limiting block 35 is engaged in the second slot 12. During installation, after the cable is placed in the cable tray trough 1, the operator can manually rotate the rotating rod 31 to move the threaded rod 32 vertically downward. Since the pressure plate 34 is engaged in the second slot 12 by the limiting block 35, the pressure plate 34 cannot rotate. Under the action of the connecting bearing 33, the lateral rotational action applied by the threaded rod 32 is counteracted, and only the pressure plate 34 moves downward to press the placed cable.

[0026] like Figure 5 As shown, a rubber pad 36 is provided at the bottom of the wire clamping plate 34 to protect the internal cables and prevent them from being easily damaged during the downward pressing of the wire clamping plate 34. The vertical plate 92 has a U-shaped groove 93 in the middle that corresponds to the wire clamping plate 34, such as... Figure 6 As shown, the pressure plate 34 has sufficient downward pressure space, ensuring the effective fixation of the cable.

[0027] like Figure 1 and Figure 2As shown, the cable tray trough 1 has corresponding assembly blocks 5 and assembly plates 6 on both sides of its front and rear openings. Both assembly blocks 5 and assembly plates 6 have threaded holes, and a second fixing bolt 7 is movably inserted into the assembly block 5. This structural design facilitates the splicing and installation of different cable tray troughs 1, making the cable tray trough 1 of this embodiment suitable for various installation scenarios and easy to transport. Furthermore, fixing plates 8 are symmetrically installed on the outer walls of both sides of the cable tray trough 1, which also facilitates the connection of the cable tray trough 1 to other supporting structures, further enabling the cable tray trough 1 to meet various installation scenarios.

[0028] Therefore, the fireproof cable tray structure described above can effectively protect the internal cables, and can also flexibly adjust the spacing between the cables according to the actual installation situation, and fix the cables to prevent the internal cables from easily shifting.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
