[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figures 1-4 This utility model provides a high-strength cable trench cover device, comprising: an outer shell plate 1, which serves as the main external structure of the entire cover device, bearing various pressures and impacts from the external environment; a spring 12 fixedly connected to the left inner wall of the outer shell plate 1, which helps the cover to return to its original position after being subjected to force through its elastic restoring force; an inner shell plate 5 fixedly connected to the end of the spring 12 away from the outer shell plate 1, which together with the outer shell plate 1 constitutes the main structure of the cover, bearing internal and external forces; the inner shell plate 5 is located inside the outer shell plate 1, and the left inner wall of the outer shell plate 1 is connected to the inner shell plate 5. A support rod 11 is fixedly connected to the left end face of the inner shell plate 5 to prevent the spring 12 from falling off. The support rod 11 is located at the center of both ends of the spring 12. A top plate 4 is fixedly connected to the right end face of the inner shell plate 5 to keep it parallel to the outer shell plate 1. The top plate 4 is located on the right side of the outer shell plate 1. A left limiting rod 2 is fixedly connected to the upper surface of the outer shell plate 1 to ensure the stability and safety of the cover plate. A right limiting rod 3 is fixedly connected to the left end face of the top plate 4 to ensure the stability and safety of the cover plate. The right limiting rod 3 and the left limiting rod 2 are both staggered and located directly above the outer shell plate 1.

[0024] A left support plate 7 is fixedly connected to the lower surface of the outer shell plate 1 to support the outer shell plate 1. A left fixing seat 9 is fixedly connected to the right surface of the left support plate 7 to install the bolt rod 14. A bolt rod 14 is fixedly connected to the right surface of the left fixing seat 9 to cooperate with the nut 13 on the right fixing seat 10 to adjust the length of the cover plate. A right support plate 6 is fixedly connected to the lower surface of the top plate 4 to install the right fixing seat 10. A right fixing seat 10 is fixedly connected to the left surface of the right support plate 6 for the rotation of the nut 13. Stabilizing rods 8 are fixedly connected to both the right surface of the left support plate 7 and the left surface of the right support plate 6. The stabilizer bar 8 is used to support the left support plate 7 and the left fixed seat 9, as well as the right support plate 6 and the right fixed seat 10. The upper end of the stabilizer bar 8 is fixedly connected to the lower surface of the left fixed seat 9 and the right fixed seat 10.
