[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] Reference Figure 1-2A cable support with a flame extinguishing protection groove, wherein the two ends of the flame extinguishing protection groove 2 are respectively fixed on a cable support 1, the cable support 1 is provided with a connecting groove 11, and a clamping groove 12 is provided on the inner side of the side wall of the connecting groove 11, the flame extinguishing protection groove 2 includes a U-shaped groove 21 and a cover plate 22 covering the top opening of the U-shaped groove 21, and outward clamping strips 212 are provided at both ends of the top opening of the U-shaped groove 21, and a clamping block 213 cooperating with the clamping groove 12 is provided on the outer side of the side wall 211 of the U-shaped groove 21, and the U-shaped groove 21 is fixed in the connecting groove 11 through the cooperation of the clamping block 213 and the clamping groove 12, and ears 222 cooperating with the clamping strip 211 are provided at both ends of the cover plate 22, and a flame extinguishing layer 223 is provided on the inner surface of the cover plate 22. The cooperation of the clamping strip 212 and the ears 222 can effectively improve the stability of the structure of the flame extinguishing protection groove 2 and the protection of the cable. Through the cooperation of the clamping groove 12 and the clamping block 213, the assembly of the cable support 1 to the flame extinguishing protection groove 2 is simple.

[0027] Preferably, the slot 12 and the block 213 are horizontally arranged on the side walls of the connecting slot 11 and the U-shaped slot 21, and the block 213 and the slot 12 are long strips with arc-shaped cross-sections. With this design, the U-shaped slot 21 can be horizontally inserted into the connecting slot 11, and can effectively adapt to the distance error between the two cable supports 1. Of course, it can also be installed from top to bottom because the side wall of the connecting slot 11 on the outside is a plate with elasticity. Of course, it is also possible to set the connecting slot 11 and the U-shaped slot 21 vertically, which can effectively prevent the flame protection slot 2 from sliding horizontally.

[0028] The inner surface of the cover 22 is provided with a flame extinguishing layer 223, which is composed of a flame extinguishing microcapsule combination wrapped with an adhesive, the capsule shell rupture temperature of the flame extinguishing microcapsule is 100-120°C, and the capsule core of the flame extinguishing microcapsule is perfluorohexanone or heptafluoropropane or aerosol or IG541. By providing the flame extinguishing layer 223, when an object set in the flame extinguishing protection groove catches fire, the fire extinguishing agent therein can be quickly released to extinguish the flame, effectively preventing and reducing fire accidents caused by cable faults.

[0029] Further, see Figure 3 A U-shaped projection 13 is provided in the middle of the connecting groove 11. The projection 13 can strengthen the strength of the connecting groove.

[0030] Embodiment 2:

[0031] This embodiment is a further improvement of the first embodiment, and the difference is that the side wall of the connection slot 11 is located above the clamping slot 12 and is folded outward, and the folding angle is greater than 0° and less than 2°. The outward bending can effectively reduce the friction between the clamping block 213 and the side wall of the connection slot 11 when the clamping block 213 is clamped downward into the connection slot 11, making the installation more convenient and reducing the damage to the connection slot 11 of the cable bracket 1.

[0032] Embodiment three:

[0033] This embodiment is a further improvement of the first or second embodiment, and the difference is that the cover plate 22 is provided with at least two bars 222 along the extension direction of the U-shaped groove, and the flame extinguishing layer 223 is provided between the bars 222, and the distance between the bars 222 on both sides and the lugs 221 is 1-1.5 times the thickness of the side wall 211 of the U-shaped groove 21, and preferably 1.5 times in this embodiment. The provision of the bars 222 can effectively prevent the side wall 211 from bending inward (excessive bending), effectively improve the stability of the flame extinguishing protection groove 2, and can effectively prevent the flame extinguishing layer 223 from flowing into the lugs 221 during production.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
