[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 A bottom box 1 with a flame extinguishing function, a wire hole 2 is provided on the surface of the bottom box 1, and fixing holes 3 for fixing switches or sockets are provided on the left and right side surfaces of the bottom box 1. It can also be other fixing devices, such as a metal sheet with fixing holes, and the metal sheet is fixed on the left and right side surfaces of the bottom box.

[0024] A flame extinguishing device is provided in the bottom box 1, and the flame extinguishing device is a coating 4, which is coated on the top surface of the inner surface of the bottom box by flame extinguishing microcapsules mixed with adhesive. The capsule shell rupture temperature of the flame extinguishing microcapsule is 100°C, and the capsule core of the flame extinguishing microcapsule is perfluorohexanone or heptafluoropropane or aerosol or IG541; the adhesive is a flame retardant hot melt adhesive, and the melting temperature of the flame retardant hot melt adhesive is 95°C. By arranging a coating with flame extinguishing microcapsules on the top of the inner surface of the bottom box, when a fire accident occurs, the fire extinguishing agent in the flame extinguishing microcapsules can be released in the first time to extinguish the fire, which can effectively reduce short-circuit fire accidents caused by sockets and switches. Of course, it is also possible to set the coating on other surfaces, but the fire extinguishing effect is better when it is set on the top surface.

[0025] Furthermore, a baffle 7 is provided in the wire hole 2 , and the baffle 7 is fixed in the wire hole 2 through a connecting rod 8 .

[0026] Further, such as Figure 2 The coating 4 also covers the bottom surface of the inner surface of the bottom box 1. Generally, the bottom box is designed to be symmetrical up and down. By providing the coating on both the bottom and the top surface, the installation direction error of the bottom box can be effectively avoided and a better fire extinguishing effect can be provided.

[0027] Further, such as Figure 3 , the coating 4 covers the entire inner surface of the bottom box 1. Compared with coating one side or two sides, the coating covers the entire inner surface, which can protect the bottom box most comprehensively, but the cost is also relatively increased a lot.

[0028] Embodiment 2:

[0029] A bottom box 1 with a flame extinguishing function is provided with a wire hole 2 on the surface of the bottom box, and fixing holes 3 for fixing switches or sockets are provided on the left and right side surfaces of the bottom box. The fixing holes 3 are used to fix switches or sockets.

[0030] The bottom box 1 is provided with a flame extinguishing device, which is a flame extinguishing patch 5, which is made of flame extinguishing microcapsules mixed with adhesive. The capsule shell rupture temperature of the flame extinguishing microcapsule is 120°C, and the capsule core of the flame extinguishing microcapsule is perfluorohexanone or heptafluoropropane or aerosol or IG541; the adhesive is a flame retardant hot melt adhesive, and the melting temperature of the flame retardant hot melt adhesive is 110°C.

[0031] The flame extinguishing patch 5 is fixed on the top surface of the inner surface of the bottom box 1 by gluing. When the wire does not pass through the wire hole 2 at the top of the bottom box, the flame extinguishing patch 5 can be arbitrarily attached to the top surface of the inner surface of the bottom box 1 ( Figure 4 ); When a wire passes through the wire hole 2 at the top of the bottom box 1, the flame extinguishing patch 5 avoids the cable fixing or is provided with an avoidance hole 6 ( Figure 5 ). The flame extinguishing patch 5 can be attached to the bottom box 1 later, that is, it can be installed on the existing bottom box 1 without replacing the bottom box, which is easy to install and effective in protection.

[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.
