Technical Field

[0001] This utility model relates to the field of installation and fixing device technology, and in particular to a public network equipment and cable installation and fixing device for subway tunnels. Background Technology

[0002] The public network communication equipment in subway tunnels is a facility deployed to ensure that passengers can use mobile phones, mobile data and other public services normally during subway operation.

[0003] Public network equipment enclosures are typically installed and fixed using standardized frames. However, the curved shape of the inner walls of subway tunnels makes positioning the frames during installation difficult and can easily lead to tilting from the workers' line of sight. Furthermore, traditional tunnel cables are fixed using brackets and straps, resulting in a chaotic layout that affects later maintenance. Therefore, a subway tunnel public network equipment and cable installation and fixing device is needed to meet these needs. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A public network equipment and cable installation and fixing device for a subway tunnel includes a tunnel wall panel 1, a public network equipment 2, and a cable 3. A first installation device 4 is installed on the tunnel wall panel 1, and the public network equipment 2 is installed on the first installation device 4. The public network equipment 2 consists of a housing 5 and a main body 6. The first installation device 4 consists of a frame 7, a sleeve 8, a screw 9, a ball shaft 10, and a connecting seat 11. There are four sleeves 8, four screws 9, four ball shafts 10, and four connecting seats 11. The housing 5 is connected to the frame 7 by screws. The sleeve 8 is rotatably connected to the frame 7. The screw 9 is threaded into the sleeve 8. The connecting seat 11 is connected to the tunnel wall panel 1 by expansion bolts. The connecting seat 11 is movably connected to the ball shaft 10, and the ball shaft 10 is connected to the end of the screw 9.

[0024] By setting the first installation device 4, the public network equipment 2 is installed and fixed on the arc surface of the tunnel wall panel 1. Through the threaded connection between the sleeve 8 and the screw 9, the total length between the screw 9 and the sleeve 8 is adjusted. Thus, the length of the screw 9 extending out of the sleeve 8 can be adjusted according to the distance between the frame 7 and the arc surface of the tunnel wall panel 1, thereby ensuring that the vertical angle of the public network equipment 2 can be adjusted after installation and avoiding tilting. At the same time, the movable connection of the connecting seat 11 on the ball shaft 10 allows the connecting seat 11 to be adaptively adjusted according to the arc surface of the tunnel wall panel 1, improving the fitting effect and stability.

[0025] Specifically, in this embodiment, one end of the sleeve 8 is closed and is provided with a connecting shaft 12. The cross-section of the connecting shaft 12 is T-shaped. The connecting shaft 12 is rotatably connected to the frame 7, which improves the connection effect between the sleeve 8 and the frame 7, while ensuring the rotatability of the sleeve 8.

[0026] Specifically, in this embodiment, the sleeve 8 is provided with anti-slip grooves 13. The anti-slip grooves 13 are arranged circumferentially and evenly on the outer wall of the sleeve 8 in the axial direction of the sleeve 8 to prevent slippage during the rotation of the sleeve 8.

[0027] Specifically, in this embodiment, the connecting seat 11 has a hemispherical hole 14, and the ball shaft 10 is movably connected in the hemispherical hole 14. The diameter of the opening of the hemispherical hole 14 is smaller than the diameter of the ball shaft 10, which provides space for the connecting seat 11 to move in the ball shaft 10, and at the same time improves the connection effect between the connecting seat 11 and the ball shaft 10, preventing separation.

[0028] Specifically, in this embodiment, a second mounting device 15 is also installed on the tunnel wall panel 1. The second mounting device 15 consists of a mounting base 16, a positioning plate 17, a sliding groove 18, a slider 19, and bolts 20. There are three positioning plates 17, three sliders 19, and three bolts 20. The mounting base 16 is connected to the tunnel wall panel 1 by expansion bolts. The sliding groove 18 has a T-shaped cross section and is opened on the mounting base 16. The slider 19 slides and adapts to the sliding groove 18. The threaded section of the bolt 20 passes through the positioning plate 17 and is threadedly connected to the slider 19. The cable 3 is electrically connected to the equipment body 6. The outer wall of the cable 3 is installed between the mounting base 16 and the positioning plate 17, as well as between adjacent positioning plates 17.

[0029] By setting the second installation device 15, the cable 3 is installed, positioned and fixed on the arc surface of the tunnel wall panel 1. By setting multiple positioning plates 17, the cable 3 is snapped into the gap between the mounting base 16 and the positioning plate 17, as well as the gap between adjacent positioning plates 17. Furthermore, by threaded connection between the bolt 20 and the slider 19, the individual position adjustment of each positioning plate 17 is achieved, thereby allowing for adaptive adjustment according to the different thicknesses of the cable 3 and improving versatility.

[0030] Specifically, in this embodiment, rubber pads 21 are provided on both inner walls of the mounting base 16 and on both sides of each positioning plate 17. The rubber pads 21 and the rubber layer covering the cable 3 form resistance, which improves the stability of the cable 3 after installation and fixation.

[0031] Specifically, in this embodiment, a limiting groove 22 is provided on the mounting base 16. The limiting groove 22 is parallel to the sliding groove 18. A limiting block 23 is slidably connected in the limiting groove 22. The limiting block 23 is connected to the positioning plate 17. After the locking force between the bolt 20 and the slider 19 is relaxed, the cooperation between the limiting groove 22 and the limiting block 23 effectively restricts the rotation effect of the positioning plate 17 with the bolt 20, improves the parallel effect between adjacent positioning plates 17 and between the positioning plate 17 and the mounting base 16, and ensures that the contact area with the cable 3 is sufficient.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
