[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The present invention provides Figure 1-7 The illustrated embodiment of a dedicated urban rail transit security monitoring integrated cable comprises a housing 1 and a cable core 14, as well as a support assembly and an installation assembly. In the structure, a plurality of U-shaped plates 15 arranged in a circular array are fixedly connected to the housing 1, and the cable core 14 is installed between the U-shaped plates 15.

[0032] Specifically, by setting the U-shaped plate 15, the position of the cable core 14 can be restricted, and the friction between the cable cores 14 can be reduced. Different cable cores 14 can be installed in a classified manner, which is convenient for subsequent maintenance and helps to improve maintenance efficiency. The U-shaped plate 15 improves the protection effect of the cable core 14, thereby reducing the occurrence of problems such as the cable core 14 being squeezed and broken, and improving the stability of the cable core 14 during use.

[0033] The support assembly in the structure is installed between the several U-shaped plates 15 to improve the structural strength of the housing 1, and includes several fixing frames 21. The fixing frames 21 in the several structures are connected by connecting assemblies;

[0034] The mounting assembly in the structure is installed on the outer wall of the shell 1 to improve the stability of the shell 1 after it is fixed, including a mounting ring plate 13, an outer sleeve 9 and an inner sleeve 6. The mounting ring plate 13, the outer sleeve 9 and the inner sleeve 6 in the structure are arranged on the shell 1 in sequence.

[0035] Specifically, by using the supporting assembly and the installing assembly in conjunction with each other, the supporting effect inside the outer shell 1 is improved, and it is also convenient to fix the position of the outer shell 1. By improving the stability of the position of the outer shell 1 after being fixed and the structural strength inside the outer shell 1, the pressure resistance of the outer shell 1 is improved, thereby improving the protection of the cable core 14.

[0036] Furthermore, the mounting ring plate 13 in the structure is fixedly connected to the outer shell 1, and the side of the mounting ring plate 13 in the structure away from the outer sleeve 9 is fixedly connected to the wedge block 2, and a plurality of mounting grooves 3 are opened on the mounting ring plate 13 in the structure, and the mounting plate 12 is rotatably connected in the mounting groove 3 in the structure.

[0037] In the structure, both the outer sleeve 9 and the inner sleeve 6 are provided with threads 8, and the outer sleeve 9 and the inner sleeve 6 are connected by threads 8. In the structure, a knob 4 is fixedly connected to the outer wall of the outer sleeve 9, and the inner sleeve 6 is fixed on the outer shell 1. In the structure, the outer sleeve 9 is slidably connected to the outer shell 1, and the end of the inner sleeve 6 away from the mounting ring plate 13 is fixedly connected to a limit plate 7 to prevent the outer sleeve 9 from detaching from the structure.

[0038] In the structure, a fixed ring plate 5 is provided between the outer sleeve 9 and the mounting ring plate 13. In the structure, the fixed ring plate 5 is slidably connected to the outer shell 1. In the structure, the fixed ring plate 5 is rotatably connected to the outer sleeve 9. The outer sleeve 9 is not easily separated from the inner sleeve 6 due to the setting of the fixed ring plate 5 and the limit plate 7. Therefore, when the user rotates the outer sleeve 9, the fixed ring plate 5 moves on the outer shell, thereby improving the connection strength between the outer sleeve 9 and the outer shell 1 and facilitating use.

[0039] Several mounting brackets 11 are fixedly connected to the fixed ring plate 5 in the structure, and a connecting plate 17 is rotatably connected to the mounting bracket 11 in the structure. A connecting groove 16 is opened at the bottom of the mounting plate 12 in the structure, and the end of the connecting plate 17 in the structure is rotatably connected to the middle of the connecting groove 16.

[0040] Specifically, when the outer sleeve 9 pushes the fixed ring plate 5 to move on the outer shell 1, the mounting frame 11 on the fixed ring plate 5 pushes the connecting plate 17 to move, thereby shortening the distance between the connecting plate 17 and the mounting ring plate 13, and then driving the mounting plate 12 to rotate along the mounting groove 3 on the mounting ring plate 13. Since the connecting plate 17 is rotatably connected to the middle part of the connecting groove 16 on the mounting plate 12, when the mounting plate 12 rotates, one side of the mounting plate 12 abuts against the tripod of the mounting outer shell 1, thereby increasing the friction between the outer shell 1 and the tripod, thereby improving the stability of the outer shell 1 during use after installation, and reducing problems such as wear of the outer shell 1 caused by unstable connection.

[0041] It also includes an auxiliary ring plate 28 used in conjunction with the mounting ring plate 13 in the structure. A wedge-shaped groove is provided in the auxiliary ring plate 28 in the structure for engaging with the mounting plate 12. A plurality of welding rods 29 are fixedly connected to the outside of the auxiliary plate in the structure. The welding rods 29 in the structure are fixed to the tripod of the mounting shell 1.

[0042] Specifically, the provision of the auxiliary ring plate 28 further improves the stability of the housing 1 after installation, and also facilitates the use of the installation components. Through the engagement between the mounting plate 12 and the wedge-shaped groove, the housing 1 will not shake after installation due to the gap between it and the tripod, thereby reducing damage to the cable core 14 caused by shaking and further improving the protection of the cable core 14.

[0043] Furthermore, the support rod 20 is rotatably connected to the fixing frame 21 in the structure through a first bolt 22. The end of the support rod 20 in the structure is provided with an arc-shaped plate 19 that abuts against the inner wall of the outer shell 1. The elastic rod 23 is fixedly connected between the two sides of the support rod 20 and the fixing frame 21 in the structure. The setting of the arc-shaped plate 19 can better fit with the inner shell 1, reduce the gap between the support rod 20 and the outer shell 1, and further improve the use effect of the support rod 20.

[0044] The connecting assembly in the structure includes two symmetrically arranged circular plates 27, and several extension plates 25 are fixedly connected to the circular plates 27 in the structure. A fixing column 24 is detachably connected between the two circular plates 27 in the structure through a second bolt 26. Several mounting holes are provided on the circular plates 27 and the extension plates 25 in the structure, and several auxiliary holes corresponding to the positions of the mounting holes in the structure are provided on the fixing frame 21 in the structure.

[0045] Specifically, multiple fixing frames 21 can be fixed together through the connection assembly, thereby reducing the difficulty of installation and facilitating manual disassembly and maintenance of a single fixing frame 21, thereby reducing unnecessary cost consumption.

[0046] Furthermore, the support assembly in the structure is provided with a plurality of reinforcing rods 18, and both ends of the reinforcing rods 18 in the structure are detachably connected to the arc-shaped plates 19 in the two support assemblies respectively.

[0047] By providing the reinforcement rod 18 , the supporting effect on the housing 1 is further improved, and the gap inside the housing 1 is reduced.

[0048] In the structure, a plurality of positioning rods 10 are fixedly connected to one side of the fixed ring plate 5 close to the mounting ring plate 13. The positioning rods 10 in the structure are slidably connected to the mounting ring plate 13, further limiting the moving path between the fixed ring plate 5 and the mounting ring plate 13, thereby improving the stability of the fixed ring plate 5 during movement.

[0049] Working principle of the present invention:

[0050] When in use, the position of the cable core 14 can be restricted by the setting of the U-shaped plate 15, and the friction between the cable cores 14 can be reduced. Different cable cores 14 can be installed in a classified manner, which is convenient for subsequent maintenance. During installation, by turning the knob 4, when the outer sleeve 9 pushes the fixed ring plate 5 to move on the outer shell 1, the mounting bracket 11 on the fixed ring plate 5 pushes the connecting plate 17 to move, thereby shortening the distance between the connecting plate 17 and the mounting ring plate 13, and then driving the mounting plate 12 to rotate along the mounting groove 3 on the mounting ring plate 13. Since the connecting plate 17 is rotatably connected to the middle part of the connecting groove 16 on the mounting plate 12, when the mounting plate 12 rotates, one side of the mounting plate 12 abuts against the tripod of the mounting shell 1, which increases the friction between the outer shell 1 and the tripod, thereby improving the stability of the outer shell 1 during use after installation, and reducing problems such as wear of the outer shell 1 caused by unstable connection.

[0051] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
