[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a technical solution: an underground fireproof tunnel of a concave integrated pipe gallery cable cabin, comprising a wire tube body 1, three first extension plates 2 are fixedly connected to the bottom of the inner wall of the wire tube body 1, a mounting shell 3 is fixedly connected to the top of the wire tube body 1, a first slide groove 4 is provided on the top of the inner wall of the wire tube body 1, an adjusting column 5 is slidably connected to the inner wall of the mounting shell 3, an extension circular plate 6 is fixedly connected to the top of the adjusting column 5, a second extension plate 7 is fixedly connected to the bottom of the adjusting column 5, four clamping plates 8 are fixedly connected to the bottom of the second extension plate 7, a threaded hole 9 is provided at the front end of the mounting shell 3, and a fixing bolt 10 is threadedly connected to the inner wall of the threaded hole 9.

[0023] The following will describe in detail the specific settings and functions of the wire clamping structure and the splicing structure.

[0024] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this implementation scheme: the staff places the wire body into the wire groove partitioned by the first extension plate 2, and then pushes the extension circular plate 6 downward to drive the adjusting column 5 to slide downward. When the second extension plate 7 drives the clamping plate 8 to the specified position, the fixing bolt 10 is screwed inward to fix the position of the adjusting column 5, so that the clamping plate 8 clamps the wire body on the inner wall of the wire tube body 1, so that the first extension plate 2 can partition and organize different wire bodies to prevent the wire bodies in the inner wall of the wire tube body 1 from getting entangled, so that the staff can distinguish different types of wire bodies for replacement or repair.

[0025] Both sides of the adjusting column 5 are fixedly connected with the limiting slider 11, and both sides of the inner wall of the mounting shell 3 are provided with the limiting slot 12. The surface of the limiting slider 11 is slidably connected with the inner wall of the limiting slot 12. When the staff moves the adjusting column 5 up and down, the sliding connection between the limiting slider 11 and the limiting slot 12 limits the movement trajectory of the adjusting column 5, preventing the staff from moving the adjusting column 5 and causing the second extension plate 7 and the clamping plate 8 to deviate from the top of the first extension plate 2, thereby achieving the effect of limiting the movement angle of the adjusting column 5.

[0026] A return spring 13 is fixedly connected to the top of the inner wall of the first slide groove 4, and the bottom end of the return spring 13 is fixedly connected to the top of the second extension plate 7. When the staff inserts the wire body into the inner wall of the wire tube body 1, the elastic force generated by the return spring 13 pushes the second extension plate 7 downward to drive the clamping plate 8 to clamp the wire body, thereby facilitating the staff to adjust the position of the second extension plate 7 and clamp the wire body through the force of the return spring 13, so as to improve the work efficiency of the staff.

[0027] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment: second slide grooves 14 are provided on both sides of the rear end of the wire tube body 1, and a limiting hole 15 is provided on the inner wall of the second slide groove 14, and third extension plates 16 are fixedly connected on both sides of the front end of the wire tube body 1, and a limiting rod 17 is slidably connected inside the third extension plate 16, and the surface of the limiting rod 17 is plugged into the inner wall of the limiting hole 15. The staff slides the third extension plate 16 into the inner wall of the second slide groove 14, and then inserts the limiting rod 17 into the inner wall of the limiting hole 15 to fix the position of the third extension plate 16 and the second slide groove 14, thereby facilitating the staff to splice and use the two wire tube bodies 1.

[0028] One end of the limiting rod 17 away from the third extension plate 16 is fixedly connected to a flat round block 18, and one end of the flat round block 18 close to the limiting rod 17 is fixedly connected to a first spring 19. One end of the first spring 19 close to the third extension plate 16 is fixedly connected to the surface of the third extension plate 16. When the staff slides the third extension plate 16 into the inner wall of the second slide groove 14, the limiting rod 17 abuts against the second slide groove 14 and is pushed upward by the flat round block 18 to pull the first spring 19 to accumulate force. When the staff moves the limiting rod 17 to the specified position again, the force released by the first spring 19 pulls the flat round block 18 to push the limiting rod 17 inwardly into the inner wall of the limiting hole 15, so that the staff can plug and fix the limiting rod 17 and the limiting hole 15.

[0029] Sealing slots 20 are provided at the bottom and top of the front end of the wire tube body 1, and sealing plates 21 are provided at the bottom and top of the rear end of the wire tube body 1. The surface of the sealing plate 21 is plugged into the inner wall of the sealing slot 20. When the staff splices two wire tube bodies 1, the sealing plate 21 is plugged into the sealing slot 20 to improve the sealing of the wire tube body 1 after splicing, isolate rainwater, and reduce damage to the wire body inside the wire tube body 1 caused by external factors.

[0030] How it works

[0031] The staff places the wire body into the wire groove partitioned by the first extension plate 2, and then pushes the extension circular plate 6 downward to drive the adjusting column 5 to slide downward so that the second extension plate 7 drives the clamping plate 8 to the specified position, and then screws the fixing bolt 10 inward to fix the position of the adjusting column 5, so that the clamping plate 8 clamps the wire body on the inner wall of the wire tube body 1, so that the first extension plate 2 can partition and organize different wire bodies to prevent the wire bodies in the inner wall of the wire tube body 1 from being entangled, so that the staff can distinguish different types of wire bodies for replacement or maintenance. When the staff moves the adjusting column 5 up and down, the sliding connection between the limiting slider 11 and the limiting slide groove 12 limits the movement trajectory of the adjusting column 5, so as to prevent the second extension plate 7 and the clamping plate 8 from deviating from the top of the first extension plate 2 when the staff moves the adjusting column 5, so as to achieve the effect of limiting the movement angle of the adjusting column 5. When the staff inserts the wire body into the inner wall of the wire tube body 1, the elastic force generated by the reset spring 13 pushes the second extension plate 7 downward to drive the clamping plate 8 to clamp the wire body, so that it is convenient for the staff to use the force of the reset spring 13 The position of the second extension plate 7 and is adjusted to clamp the wire body, so that the staff can improve the work efficiency. The staff slides the third extension plate 16 into the inner wall of the second slide groove 14, and then inserts the limiting rod 17 into the inner wall of the limiting hole 15 to fix the position of the third extension plate 16 and the second slide groove 14, so as to facilitate the staff to splice the two wire tube bodies 1. When the staff slides the third extension plate 16 into the inner wall of the second slide groove 14, the limiting rod 17 abuts against the second slide groove 14 and is pushed upward by the force to pull the flat round block 18 The first spring 19 accumulates force. When the staff moves the limit rod 17 to the specified position, the first spring 19 releases the force to pull the flat round block 18 to push the limit rod 17 to be inserted into the inner wall of the limit hole 15, so that the staff can plug and fix the limit rod 17 and the limit hole 15. When the staff splices the two wire tube bodies 1, the sealing plate 21 is plugged into the sealing slot 20 to improve the sealing of the wire tube body 1 after splicing, isolate rainwater, and reduce the damage to the wire body inside the wire tube body 1 caused by external factors.
