[0025] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] For ease of description, the words "up," "down," "left," and "right" appearing in this utility model only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figure 1-7 As shown, this utility model provides a technical solution: a cable tray, including a frame 1 and a capping mechanism 7. The frame 1 has spaced heat dissipation holes 2 on both sides, and a drainage mechanism 3 is provided below the frame 1. A second dustproof net 4 is installed on the inner wall of the frame 1 near the heat dissipation holes 2 by screws. A sliding groove 11 is welded to the inner side of the frame 1. A limiting mechanism 5 is provided on one side of the sliding groove 11. A first insertion block 6 and a second insertion block 8 are connected to one side of the frame 1. A first slot 12 and a second slot 10 are provided on the other side of the frame 1. The capping mechanism 7 is located above the frame 1. The two ends of the frame 1 are provided with docking mechanisms 9.

[0029] according to Figure 1-3 As shown, the drainage mechanism 3 includes a drainage trough 31, a first dustproof net 32, side frames 33, and crossbars 34. The drainage trough 31 is provided at the bottom of the frame 1. The first dustproof net 32 ​​is installed inside the drainage trough 31. Side frames 33 are welded to both sides of the frame 1 near the drainage trough 31. Crossbars 34 are provided on one side of the side frames 33 at intervals. The drainage trough 31 is an inclined structure.

[0030] In practice, since some cables are laid in the open environment, water may enter the cable tray. The water can be drained into the drainage ditch 31 through the side frame 33 and the crossbar 34. Then the water slides from the drainage ditch 31 into the first dustproof net 32, which can quickly drain the water in the frame 1 to the outside. The heat dissipation hole 2 can dissipate heat from the cable. The first dustproof net 32 ​​and the second dustproof net 4 can block dust from entering the frame 1, which can prevent water and dust accumulation from affecting the service life of the cable.

[0031] according to Figure 1 and Figure 7 As shown, the limiting mechanism 5 includes a pressure plate 51, a limiting spring 52, a connecting rod 53, and a limiting plate 54. The limiting plate 54 is slidably connected to one side of the slide groove 11. The limiting spring 52 is provided in the inner groove of the limiting plate 54. The connecting rod 53 is provided on one side of the limiting spring 52, and the connecting rod 53 is slidably connected to the inner groove of the limiting plate 54. One end of the connecting rod 53 is connected to the pressure plate 51. The limiting plate 54 has three internal openings.

[0032] In practice, since multiple cables need to be laid in the cable tray, it is usually done by bundling the cables together with multiple binding wires and then placing them directly on the cable tray. This is quite cumbersome. A better approach is to place the cables on the crossbar 34, then place the limiting plate 54 on both sides in the sliding groove 11, and then push it downwards so that the opening of the limiting plate 54 is locked on the outside of the cable, which can divide the cable into three bundles. Then push the top plate 72 in, so that the top plate 72 presses down on the limiting plate 54. Then, the limiting spring 52 rebounds and pushes the connecting rod 53 downwards, so that the connecting rod 53 drives the pressure plate 51 to hold the cable and prevent the cable from loosening. This allows for quick cable laying, cable organization, and facilitates subsequent cable maintenance, thus improving the practicality of the cable tray.

[0033] according to Figure 1-3 As shown, the capping mechanism 7 includes splicing blocks 71, a top plate 72, and splicing grooves 73. The top plate 72 is provided above the frame 1, and splicing blocks 71 are connected to both sides of the top plate 72. Splicing grooves 73 are provided on both sides of the frame 1 near the splicing blocks 71. The splicing blocks 71 and splicing grooves 73 are T-shaped.

[0034] In practice, after the cable is laid, the splicing blocks 71 on both sides of the top plate 72 can be aligned with the splicing groove 73, and then the top plate 72 can be pushed to one side to install the top plate 72 onto the frame 1 to protect the cable.

[0035] according to Figure 2 , Figure 4 and Figure 5 As shown, the docking mechanism 9 includes a rotating shaft 91, a connecting pin 92, a limiting groove 93, a limiting block 94, a fastening ring 95, and a return spring 96. The rotating shaft 91 is installed at one end of the frame 1, and the return spring 96 is provided in the groove at the other end of the frame 1. The limiting block 94 is provided on one side of the return spring 96. The connecting pin 92 is movably sleeved on the outside of the rotating shaft 91. The limiting groove 93 is opened at one end of the connecting pin 92. The fastening ring 95 is sleeved on the outside of the limiting block 94. The fastening ring 95 and the limiting block 94 are connected by threads.

[0036] In practice, when connecting one cable tray to another, inserting the first plug 6 and the second plug 8 into the first slot 12 and the second slot 10, and then rotating the connecting pin 92 by rotating the rotating shaft 91, the connecting pin 92 will rotate to the limiting block 94, causing the connecting pin 92 to press against the limiting block 94 and the return spring 96. Then the return spring 96 will rebound and drive the limiting block 94 into the limiting groove 93. Then the fastening ring 95 will be rotated to make the limiting block 94 and the limiting groove 93 stably engaged. This allows for quick splicing of cable trays and improves the convenience of cable trays.

[0037] Working principle: When using this type of cable tray, firstly, the cable can be laid in the frame 1. The cable is limited by the limiting mechanism 5. Then, the cable tray is connected to another cable tray by the docking mechanism 9. Then, the top of the frame 1 is sealed and protected by the capping mechanism 7. The heat dissipation holes 2 can dissipate heat from the cable. The drainage mechanism 3 can drain the accumulated water. The first dustproof net 32 ​​and the second dustproof net 4 prevent dust from entering the frame 1, which improves the convenience and practicality of the cable tray. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] The above-described specific embodiments are merely specific examples of this utility model. The patent protection scope of this utility model includes, but is not limited to, the product form and style of the above-described specific embodiments. Any appropriate changes or modifications made by a person skilled in the art that conform to the claims of this utility model should fall within the patent protection scope of this utility model.
