[0020] 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.

[0021] Embodiment 1:

[0022] Reference Figure 1 A flame extinguishing trough comprises a U-shaped trough 1 and a cover 2 covering the top opening of the U-shaped trough 1, wherein the U-shaped trough 1 comprises a bottom plate 11 and side plates 12 located on both sides of the bottom plate, and outward clamping strips 13 are provided at both ends of the top opening of the U-shaped trough 1 (i.e., the top of the side plates 12), and ears 21 cooperating with the clamping strips 13 are provided at both ends of the cover 2. The cooperation between the ears 21 and the clamping strips 13 can effectively prevent the side plates 12 of the U-shaped trough 1 from bending outward, thereby greatly improving the stability of the flame extinguishing trough.

[0023] The inner surface of the cover 2 between the tabs 21 is provided with a flame extinguishing layer 24, 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 24, when an object set in the flame extinguishing 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.

[0024] Furthermore, a slot 23 is provided between the flame extinguishing layer 24 and the ear 13. The length of the slot 23 is 1-2 times the wall thickness of the U-shaped groove side plate. The width of the slot 23 is determined according to the actual structure, as long as it does not hinder the cooperation between the ear 21 and the card strip 13 and can prevent the side plate 12 from bending inward (excessive bending). In this embodiment, the width of the slot 23 is preferably 2 times the wall thickness of the layer. By providing the slot 23, the installation of the cover 2 and the U-shaped groove 1 can be achieved by first cooperating with the ear 21 on one side and the card strip 13, and then engaging the other side. The installation method is more convenient, saves time, and the installation will not cause structural damage. The flame extinguishing layer 24 can also block the side plate 12, effectively preventing the side plate 12 from bending inward excessively, and effectively improving the stability of the flame extinguishing groove. At the same time, the width of the slot 23 should not be too large. If the width is too large, a very thick flame extinguishing layer is required to achieve the blocking effect, which will also affect the engagement of the ear 21 and the card strip 13, which is not worth the loss.

[0025] Embodiment 2:

[0026] Reference Figure 2-3 A flame extinguishing trough comprises a U-shaped trough 1 and a cover 2 covering the top opening of the U-shaped trough 1, wherein the U-shaped trough 1 comprises a bottom plate 11 and side plates 12 located on both sides of the bottom plate, and outward clamping strips 13 are provided at both ends of the top opening of the U-shaped trough 1 (i.e., the top of the side plates 12), and ears 21 cooperating with the clamping strips 13 are provided at both ends of the cover 2. The clamping ears 21 and the clamping strips 13 cooperate to effectively prevent the side plates 12 of the U-shaped trough 1 from bending outward.

[0027] Two baffles 22 are provided on the inner surface of the cover 2. The cross-sectional shape of the baffle 22 is an arc shape. A slot 23 is provided between the baffle 22 and the ear 21. The width of the slot 23 is 1-2 times the wall thickness of the U-shaped groove, and preferably 1.5 times in this embodiment. The setting of the baffle 22 can effectively prevent the side panel 12 of the U-shaped groove 1 from bending inward excessively. At the same time, the baffle 22 can also prevent the flame extinguishing layer 24 from flowing toward the ear 21 during production, effectively avoiding the situation where the ear 21 and the clamping strip 13 are not compatible.

[0028] When the width of the slot 23 is equal to the wall thickness of the U-shaped slot 1, the cover 2 can generally only be installed by sliding in horizontally from the side, and the direct insertion method is likely to cause damage to the ear 21 or make installation difficult. When the width of the slot 23 is 1.5 times the wall thickness of the U-shaped slot 1, the installation method of inserting the ear 21 into the clip strip 13 becomes simple, making the installation of the cover and the U-shaped slot 1 simple, and effectively preventing the side panels of the U-shaped slot 1 from bending inward and outward, greatly improving the stability of the flame extinguishing slot.

[0029] A flame extinguishing layer 24 is provided between the two baffles 22. The flame extinguishing layer 24 is composed of a flame extinguishing microcapsule combination wrapped by an adhesive. The capsule shell rupture temperature of the flame extinguishing microcapsule is 100-120°C. The capsule core of the flame extinguishing microcapsule is perfluorohexanone or heptafluoropropane or aerosol or IG541. By providing the flame extinguishing layer 24 between the baffles, when an object set in the flame extinguishing groove catches fire, the fire extinguishing agent therein can be quickly released to extinguish the flame, thereby effectively preventing and reducing fire accidents caused by cable faults.

[0030] Furthermore, a card hole 14 is provided in the card strip 13 ( Figure 4 ), the two flame extinguishing grooves are connected by inserting the clamping block into the clamping hole 14.

[0031] Furthermore, the cross-sectional shape of the baffle bar 21 is square ( Figure 6 ).

[0032] Embodiment three:

[0033] This embodiment is a further improvement of the first or second embodiment, and the difference is: Figure 5 The angle a between the side plate 12 and the bottom plate 11 is greater than 90° and less than 93°, and is preferably 91° in this embodiment. The side plate 12 is slightly tilted outward during production. During installation, the side plate 12 can be corrected by the cooperation between the latch 21 of the cover 1 and the latch strip 13, that is, the angle a between the side plate 12 and the bottom plate 11 is equal to 90°, which can further effectively prevent the side plate from bending inward and ensure the stability of the flame extinguishing groove.

[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.
