Description

Technical Field

[0001] This utility model relates to the field of PVC wire trough technology, and more specifically, to a wire trough for installation and protection. Background Technology

[0002] As an electrical tool for organizing, fixing, and protecting electrical wires, the insulation between the wire duct and the wire is crucial. Wire duct installation is generally destructive, using fasteners such as steel nails, expansion plugs, and self-tapping screws driven into the wall through the duct. In this method, the nail heads remain inside the duct. Since these fasteners are conductive, they can damage the insulation of the duct itself. Furthermore, the sharp rubber tips of the nails can chafe the protective insulation of the wires during wiring, creating a safety hazard. Non-destructive installation methods, such as adhesive bonding, often lack sufficient adhesion and easily peel off with the wall surface. Therefore, these methods no longer meet current fire-resistant insulation requirements for electrical wires and cables. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies where fasteners such as steel nails can damage the insulation of the cable tray, and to provide a cable tray installation protection method that can maintain high insulation and improve the safety of the cable tray when using fasteners such as steel nails to fix the cable tray.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A cable tray with installation protection is provided, including a cable tray body, a partition, a cable tray cover, and a fastener for fixing the cable tray body. The partition is detachably installed inside the cable tray body, and the partition divides the cavity inside the cable tray body into a first mounting cavity for installing the fastener and a second mounting cavity for fixing wires. One end of the fastener passes through the bottom of the cable tray body, and the other end is located in the first mounting cavity. The cable tray cover is detachably installed at the opening at the top of the cable tray body.

[0006] This utility model provides an installation and protection system for cable trays. During installation, the bottom of the cable tray body abuts against the wall, and the fixing components pass through the bottom of the cable tray body and into the wall. A partition is installed inside the cable tray body, and the wires are fixed in the second mounting cavity. Finally, the cable tray cover is installed, completing the cable tray installation. The partition separates the fixing components from the wires, preventing non-insulated fixing components such as steel nails from scratching the wire insulation and damaging the cable tray's insulation. This provides insulation protection for the second mounting cavity of the cable tray, thereby preventing leakage and eliminating safety hazards.

[0007] Furthermore, the inner wall of the main body of the cable tray is provided with a first fastening part, and the partition is provided with a second fastening part, the first fastening part and the second fastening part being interlocked with each other. When installing the partition, the first fastening part and the second fastening part are fastened together, thereby installing the partition on the inner wall of the main body of the cable tray.

[0008] Furthermore, the first fastening part is an arc-shaped protrusion, and the second fastening part is a groove that mates with the first fastening part. Both the first and second fastening parts have at least two sets, and the opening directions of each set of the second fastening parts are intersecting or opposite. When installing the partition, the arc-shaped protrusions of at least two sets of the first fastening parts are inserted into the corresponding grooves of the second fastening parts to complete the installation of the partition. The structure is simple and the operation is convenient.

[0009] Furthermore, the first fastening part is disposed on the inner wall of the side wall of the cable tray body, and the partition plate has second mounting ribs on its two opposite sides. The second fastening part is disposed on the wall surface opposite to the first fastening part of the second mounting rib. When installing the partition plate, the first fastening part on the side wall of the cable tray body is engaged with the second fastening part on the second mounting rib. The side wall of the cable tray body limits the second mounting rib, improving the stability of the partition plate installation.

[0010] Furthermore, the inner wall of the bottom of the cable tray body is provided with two sets of first mounting ribs, and the first fastening part is provided on the opposite wall surface of the two sets of first mounting ribs. The partition is provided with two sets of second mounting ribs, and the two sets of second fastening parts are respectively provided on the two sets of second mounting ribs. The opening directions of the two sets of second fastening parts are opposite, and they are respectively engaged with the two sets of first fastening parts. When installing the partition, the two sets of first fastening parts are respectively engaged into the two sets of second fastening parts to complete the installation. By providing the first fastening part on the first mounting rib, compared with providing the first fastening part on the side wall of the cable tray body, the space for installing cables can be expanded.

[0011] Furthermore, the top of the second mounting rib is provided with a first guide surface that mates with the first fastening part. When installing the partition, the partition is moved so that the first guide surface contacts the lower surface of the first fastening part. The first guide surface allows the first fastening part to be easily engaged into the second fastening part by sliding or pressing the partition, reducing the difficulty of installing the partition.

[0012] Furthermore, the bottom outer side of the main body of the cable tray is provided with several first protruding ribs, and there are gaps between the first protruding ribs that allow the fixing member to pass through. The first protruding ribs can improve the structural strength of the main body of the cable tray and prevent the cable tray from deforming during installation and disassembly; at the same time, the first protruding ribs can reduce the contact area between the main body of the cable tray and the wall, so that the cable tray can fit better with the wall, making the cable tray more secure and the cable tray more aesthetically pleasing after installation.

[0013] Furthermore, the bottom inner side of the main body of the cable tray is provided with several second protruding ribs, and there are gaps between the second protruding ribs that allow the fixing member to pass through. The second protruding ribs can improve the structural strength of the main body of the cable tray and prevent the cable tray from deforming during installation and disassembly.

[0014] Furthermore, the main body of the cable tray is snap-fitted to the cover. This snap-fit ​​connection allows for easy and quick connection between the cable tray body and cover, improving installation efficiency.

[0015] Furthermore, a set of first limiting ribs is provided on each of the two opposite sidewalls of the main body of the cable trough, and two sets of second limiting ribs are provided on the cable trough cover. The upper surface of the first limiting ribs is provided with a first limiting surface, and the lower surface of the second limiting ribs is provided with a second limiting surface. The two sets of first limiting surfaces abut against the two sets of second limiting surfaces respectively. When installing the cable trough cover, the second limiting surfaces of the two sets of second limiting ribs abut against the corresponding first limiting surfaces. The mutual limiting between the two sets of first limiting surfaces and second limiting surfaces can prevent the cable trough cover from falling out of the main body of the cable trough.
