DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] like Figure 1 and Figure 2 The figure shows a fire-fighting dual-flame-retardant, bend-resistant cable assembly, comprising a flame-retardant sleeve; a bending tube 4 is installed between two sets of flame-retardant sleeves 1, and a cable is inserted into the two sets of sleeves 1 and the bending tube 4. The two sets of sleeves 1 and the bending tube 4 form a protective sleeve structure for bending the cable. The bending tube 4 and the flame-retardant sleeve 1 further protect the cable, preventing flame retardancy and bending from contact with hard objects.

[0024] The flame retardant sleeve 1 includes a cable flame retardant sleeve 7, a liquid supply connector 9 and an adapter 5;

[0025] The liquid supply connector 9 connects to the flame-retardant inner tube 8 within the cable flame-retardant sheath 7 via the liquid supply mounting terminal 11. The liquid supply connector 9 is responsible for both supplying and discharging the flame-retardant liquid. In the event of an emergency, the leaking flame-retardant liquid is used to complete the initial flame-retardant process, allowing personnel sufficient time to extinguish the fire.

[0026] The adapter 5 is sealed and docked with the bent tube 4 through the threaded sleeve 2. The design of the threaded sleeve 2 can improve the sealing performance of the docking and is also convenient for operation.

[0027] like Figure 1 and Figure 2 As shown, the front and back sides of the bending tube 4 are integrally connected with reinforcing ribs 3. The reinforcing ribs 3 improve the structural strength of the bending tube 4.

[0028] like Figure 1 and Figure 2 As shown, six groups of flame retardant inner tubes 8 are evenly distributed inside the cable flame retardant sheath 7, and the flame retardant inner tubes 8 are filled with flame retardant liquid 14; wherein, the flame retardant inner tubes 8 can store the flame retardant liquid 14, and the flame retardant liquid 14 can improve the flame retardant performance of the cable.

[0029] A flame retardant filling layer 12 is filled between two adjacent groups of flame retardant inner tubes 8, wherein the flame retardant filling layer 12 serves as a further flame retardant enhancement structure and also ensures that the position of the flame retardant inner tube 8 does not shift inside the tube.

[0030] The inner wall of the flame retardant filling layer 12 retains a cable jack 13. The cable jack 13 can be inserted into the cable to protect the cable.

[0031] like Figure 1 and Figure 2 As shown, the liquid supply connector 9 is embedded with a liquid supply mounting end 11, on which a liquid supply valve 6 and a liquid drain valve 10 are mounted. The liquid supply valve 6 and the liquid drain valve 10 are evenly connected to the flame retardant inner tube 8. The liquid supply valve 6 and the liquid drain valve 10 mounted on the liquid supply connector 9 allow staff to supply flame retardant liquid and to check whether the flame retardant liquid has failed and drain the flame retardant liquid.

[0032] like Figure 1 and Figure 2 As shown, the adapter 5 retains a sealing end along the root of the threaded sleeve 2.

[0033] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, they can make several improvements and modifications without departing from the principles of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
