DETAILED DESCRIPTION

[0021] 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.

[0022] Embodiment 1:

[0023] Reference Figure 1-3 A flame extinguishing side wall cable bracket comprises a cable bracket 1, a connecting fixture 2 and a ∩-shaped flame extinguishing cover 3.

[0024] The cable holder 1 includes a fixing frame 11 for fixing on the side wall and a placing beam 12 arranged on one side of the fixing frame 11. The placing beam 12 includes a horizontal placing arm 121 and a reinforcing arm 122 located below one side of the placing arm 121. The placing arm 121 and the reinforcing arm 122 form a shape of "┐" or "ㅜ".

[0025] The side of the connecting fixture 2 is provided with a clamping groove 21, which is a transverse trapezoidal groove with a short side opening. The clamping groove 21 of the connecting fixture 2 is inserted into the placement arm 121, so that the shape of the clamping groove 21 is a structure that is large inside and small outside, and can be directly and forcefully clamped on the cable bracket. A clamping groove 22 is provided above the connecting fixture 2. The installation of the connecting fixture 2 and the cable bracket 1 is simple and the construction is simple. Generally, one cable bracket 1 is equipped with two connecting fixtures 2 for use. When the placement beam of the cable bracket 1 is longer than 12 and the cables need to be laid in isolation, more than two connecting fixtures 2 can be used in conjunction with the ∩-shaped flame extinguishing cover 3 for isolation and protection.

[0026] The two ends of the ∩-shaped flame extinguishing cover 3 are fixed in the slots 22 of the two connecting fixtures 2. The flame extinguishing layer 31 is made of flame extinguishing microcapsules 32 wrapped with an adhesive, and the capsule core of the flame extinguishing microcapsules 32 is a fire extinguishing agent. The fire extinguishing agent can be a halogenated alkane, heptafluoropropane, or perfluorohexanone. The fire extinguishing agent can be solidified by microcapsule technology (diameter of 1-1000μm), and the fire extinguishing agent is wrapped in the capsule core of the microcapsule to effectively prevent the volatilization of the fire extinguishing agent. When the cable catches fire, the flame extinguishing microcapsules in the flame extinguishing layer will melt and rupture when reaching a predetermined temperature such as 90 or 150°C, releasing the fire extinguishing agent therein to extinguish the flame.

[0027] Furthermore, two card slots 22 are provided above the connecting fixture 2. In this way, when it is necessary to isolate and lay cables, such as isolating two parts, only three connecting fixtures are needed to complete the installation, which not only saves costs, but also saves installation steps and time.

[0028] Furthermore, the flame extinguishing layer 31 is synthesized by wrapping the flame extinguishing microcapsules 32 with flame retardant hot melt adhesive, and the flame extinguishing microcapsules 32 are evenly distributed on the surface of the flame extinguishing layer 31. The use of the flame retardant hot melt adhesive does not produce harmful substances when extinguishing a fire, which is environmentally friendly. The flame extinguishing microcapsules 32 are evenly distributed on the surface of the flame extinguishing layer 31, so that the flame extinguishing effect of the flame extinguishing layer is better, easier to excite, and more stable.

[0029] Embodiment 2:

[0030] This embodiment is a further improvement of the first embodiment, the difference is: Figure 4-5The clamping groove 21 of the connecting fixture 2 is located at the opening above the placing arm 121, and an anti-dropping groove 24 is provided. The shape of the anti-dropping groove 24 is "├" shaped, and the anti-dropping clamp 4 is provided with an anti-dropping clamp block 41 in the shape of "├" for being clamped in the anti-dropping groove 24. The connecting fixture 2 and the anti-dropping clamp 4 are respectively located on both sides of the reinforcing arm 122. The anti-dropping clamp 4 can effectively prevent the connecting fixture 2 from falling off, further ensuring the connection and installation stability of each component.

[0031] Furthermore, a connection slot 23 is provided at the opposite outer ends of the connection fixture 2 and the anti-dropping fixture 4, and a flame extinguishing baffle 5 can be inserted into the connection slot 23, and a flame extinguishing layer is provided on the upper surface and / or lower surface of the flame extinguishing baffle 5. The flame extinguishing baffle 5 can not only support the cable, but also protect the cable through the flame extinguishing layer on the upper surface and / or lower surface of the flame extinguishing baffle 5.

[0032] 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.
