Description

Technical Field

[0001] This invention relates to the field of cable tray technology, and in particular to a cable tray for low-voltage electrical construction. Background Technology

[0002] Cable trays are classified into various structures, including trough-type cable trays, tray-type cable trays, ladder-type cable trays, and mesh cable trays. They can be installed independently or laid on various buildings and pipe rack supports. They feature simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. These are cable trays installed outdoors on buildings.

[0003] The existing cable trays have a relatively simple structure and do not have any internal cable management features, resulting in a messy distribution of network cables during cable routing. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a cable tray for low-voltage electrical construction, comprising a cable tray body, with a connector at one end of the cable tray body. The connector is U-shaped, and both the connector and the end of the cable tray body have through holes. A cover plate is fastened to the upper end of the cable tray body. The connector connects and fixes multiple cable tray bodies together, while the cover plate covers the upper end of the cable tray body, making the device a relatively closed structure.

[0005] The cable tray body has several U-shaped components fixedly connected internally. Several cable management plates are stacked inside each U-shaped component, and several cable management slots are equidistantly arranged on the upper end of each cable management plate. The U-shaped components improve the structural strength of the cable tray body, and their cross-sectional shape matches that of the channel steel, allowing the cable management plates to be accommodated within them. The cable management plates and their cable management slots ensure neat cabling of the network cables.

[0006] Preferably, the inner side of the U-shaped component is provided with several ribs. The ribs are provided to further improve the structural strength of the U-shaped component.

[0007] Preferably, the cover plate is bent on both sides to form receiving grooves, and the upper parts of both sides of the cable tray body are bent inward to form second arc-shaped bends, and the receiving grooves and second arc-shaped bends cooperate with each other. That is, the cover plate is fixedly connected to the cable tray body through the receiving grooves and second arc-shaped bends.

[0008] Preferably, the cover plate has its two sides bent to form a first arc-shaped bend, and the first arc-shaped bend is located below the receiving groove. The first arc-shaped bend facilitates the cover plate's fastening to the cable tray body.

[0009] The beneficial effects of this invention are as follows:

[0010] 1. A cable management board is provided, and the cable management board has cable management slots. The network cables are restrained in the cable management slots, ensuring that the network cables are arranged neatly.

[0011] 2. It is equipped with U-shaped parts, which not only increase the structural strength of the cable tray body, but also accommodate and restrict the position of the cable tie plate.

[0012] 3. The edges of the cover plate and the main body of the cable tray are provided with a first arc-shaped bend and a second arc-shaped bend. The arc-shaped structure not only facilitates the fastening of the cover plate, but also prevents hands from being scratched during construction. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] like Figures 1 to 4 As shown, a cable tray for low-voltage electrical construction includes a cable tray body 2 with a U-shaped cross-section. The interior of the cable tray body 2 accommodates low-voltage cables such as network cables. A connector 1 is provided at the end of the cable tray body 2. The connector 1 is U-shaped, and both the connector 1 and the end of the cable tray body 2 are provided with through holes. When in use, the connector 1 is placed inside the cable tray body 2, and then bolts or other connecting components are used to achieve a fixed connection between the connector 1 and the cable tray body 2. Note that the connector 1 connects multiple cable tray bodies 2. A cover plate 3 is fastened to the upper end of the cable tray body 2, and the cover plate 3 is fixed to the cable tray body 2 to form a relatively closed structure.

[0021] Several U-shaped parts 4 are fixedly connected inside the main body 2 of the cable tray. The U-shaped parts 4 are fixedly connected inside the main body 2 of the cable tray by welding, thereby improving the overall structural strength of the main body 2 of the cable tray. Several cable bundles 5 are stacked inside the U-shaped parts 4. The arrangement of multiple cable bundles 5 can accommodate more network cables. Several cable bundle slots 6 are equidistantly arranged on the upper end of the cable bundles 5. Placing the network cables in the cable bundle slots 6 ensures that the network cables are neat.

[0022] Several ribs 7 are provided on the inner side of the U-shaped component 4. The ribs 7 are provided to improve the structural strength of the U-shaped component 4.

[0023] The cover plate 3 is bent on both sides to form a receiving groove 10, and the upper parts of both sides of the cable tray body 2 are bent inward to form a second arc-shaped bend 9. The receiving groove 10 and the second arc-shaped bend 9 cooperate with each other, that is, the connection between the cover plate 3 and the cable tray body 2 is realized through the structure of the receiving groove 10 and the second arc-shaped bend 9.

[0024] The two sides of the cover plate 3 are bent to form the first arc-shaped bend 8, and the first arc-shaped bend 8 is located below the receiving groove 10. The arrangement of the first arc-shaped bend 8 and the second arc-shaped bend 9 makes the arc-shaped structure of the cover plate 3 easy to close when it is fastened, and at the same time, the arc-shaped structure does not scratch the hand.

[0025] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
