[0021] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Embodiment one:

[0023] With reference to Figures 1-3 , a multi-stage adjusting switch joint fire extinguishing sheath, comprising a plurality of fire extinguishing rings 1, as shown in Figure 3 , a plurality of fire extinguishing rings 1 are spliced together from bottom to top and the inner holes 2 are gradually reduced. Through this splicing, the fire extinguishing sheath can be adapted to cables / wires of multiple different sizes, realizing multi-stage adjustment. In use, according to the diameter size of the cable / wire, the smaller size fire extinguishing rings can be removed from top to bottom, and then the fire extinguishing sheath of appropriate size is sleeved on the cable at the connection between the switch and the cable / wire. The smaller size fire extinguishing rings removed at the same time can also be used again on smaller size cables / wires, realizing multiple uses.

[0024] The fire extinguishing ring 1 is made of fire extinguishing microcapsules and glue, compared with the existing fire extinguishing sheath which only has fire extinguishing coating on the inner surface, the entire fire extinguishing sheath can achieve fire extinguishing, and the after-fire effect is better. The fire extinguishing microcapsules contain perfluorohexanone extinguishing agent, when the switch joint of the cable / wire is short-circuited and on fire, the flame temperature will excite the fire extinguishing microcapsules in the fire extinguishing ring 1, so that the fire extinguishing microcapsules are broken to release the perfluorohexanone extinguishing agent to extinguish the fire.

[0025] Further, as shown in Figure 4 , the fire extinguishing sheath is provided with an opening 3 penetrating the inside and outside. The opening 3 is provided to facilitate the installation of the switch joint of the existing line, without the need to disconnect and remove the installation.

[0026] Further, as shown in Figure 1 , the fire extinguishing ring 1 is provided with a size mark on each layer, which facilitates the quick installation of the required size.

[0027] Further, the glue is a fire-retardant glue, which can prevent the fire extinguishing sheath from being ignited by the flame and more effectively extinguish the fire.

[0028] Example two:

[0029] The difference between this embodiment and example one is that, referring to Figure 5 , the diameters of the fire extinguishing rings 1 of the fire extinguishing sheath gradually decrease from outside to inside and are peelably spliced inside and outside. Compared with example one, the structure of this embodiment can better sleeve the fire extinguishing sheath on the cable / wire and fix it at the switch joint, effectively protecting the short-circuit fire at the switch joint of the cable / wire.

[0030] Further, the heights of the fire extinguishing rings 1 gradually increase from outside to inside, which facilitates the setting of the size mark on each layer of the fire extinguishing ring 1.

[0031] Further, as shown in Figure 6 , the fire extinguishing ring 1 is provided with a peelable adhesive joint 4, which can be understood as that the fire extinguishing ring 1 is formed by rolling a square sheet into a circle, and the two ends of the sheet are adhered to form a ring by an adhesive, or the joint is directly left and the ring is poured, which facilitates the peeling of the fire extinguishing ring 1 when the fire extinguishing sheath is used.

[0032] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
