[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0032] like Figure 1 As shown, the present invention provides a floor cable trunking with an access opening, comprising a U-shaped trunking body 1, which defines a channel for accommodating cables. Horizontally extending outward from the top of the sidewalls of the trunking body are flanges 11, facilitating the securing of a cover plate 2. The U-shaped structure not only provides ample storage space but also enhances the overall strength of the trunking.

[0033] The cover plate 2 covers the trunking body 1 and is secured to the flange 11 with screws, ensuring a tight fit between the cover plate 2 and the trunking body 1. Several inspection openings 3 are provided on the cover plate 2 to facilitate routine cable maintenance. These inspection openings 3 are designed to avoid the need to completely remove the cover plate 2 for cable inspection or maintenance.

[0034] like Figure 1 and Figure 3 As shown, the access cover 4 conforms to the shape of the access opening 3 and consists of a fixed section 41, an intermediate section 42, and an extended section 43. One end of the fixed section 41 is hinged to one side of the access opening 3, while the intermediate section 42 and the extended section 43 slide into the interiors of the fixed section 41 and the intermediate section 42, respectively. This design allows the access cover 4 to slide and retract as needed, providing ample clearance for maintenance while ensuring a smooth and airtight seal when closed.

[0035] At one end of the inspection opening 3 away from the hinge of the inspection cover 4, a strap 5 is fixedly provided for the extension section 43 to rest on. The strap 5 is designed to stabilize the position of the extension section 43 when the inspection cover 4 is closed, ensuring that the inspection port is sealed reliably.

[0036] The extension section 43 is provided with a groove 6 for facilitating the lifting of the inspection cover 4 and the retraction of the extension section 43 to the middle section 42. By providing the groove 6, the user can conveniently operate the inspection cover 4, simplifying the opening and closing process during cable maintenance.

[0037] like Figure 2 indivual Figure 5 As shown, in order to further improve the strength of the trunking body 1, a number of reinforcing ribs 7 are fixedly provided on the convex edge 11 and the side walls of the trunking body 1. The reinforcing ribs 7 can effectively improve the overall compression and deformation resistance of the trunking.

[0038] like Figure 3 As shown, an L-shaped sealing gasket 8 is installed between the cable trough cover 2 and the flange 11. This improves the cable trough's sealing performance and prevents dust and moisture from entering the interior, achieving an overall IP67 rating. This design allows the cable trough to be used outdoors or in humid environments, ensuring cable safety. The sealing gasket 8 is made of silicone rubber, which offers excellent heat, weather, and chemical resistance.

[0039] like Figure 1 As shown, to prevent the cable from loosening during use, a fixing member 9 is further provided inside the trunking body 1. The fixing member 9 is in the shape of an inverted "Ω" and has a fixing plate at its bottom. This can firmly fix the cable in place, preventing the cable from loosening or becoming entangled due to vibration or external forces, ensuring orderly cable management and safe operation.

[0040] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
