Problems solved by technology
[0003] The multimedia box is a centralized box for weaker voltage lines. It is generally used in modern home decoration, such as network cables, telephone lines, and TV antennas, etc. can be placed in it; The internal space is narrow, so it is easy to cause the heat generated not to be discharged in time, which will cause the insulation layer of the cable to soften, reduce the service life of the cable, and even cause the risk of electric leakage
If the interior of the multimedia box is artificially ventilated or cooled, it will cause inconvenience to the user, and it is difficult to cool down in time

Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] see Figure 1 to Figure 4 Shown, a kind of specific embodiment of multimedia box of the present invention. The multimedia box includes a multimedia box body 1 and a sliding door 2 matched with the box body 1. In the box body 1, a public warehouse 11, a socket warehouse 12 and a panel warehouse 13 are sequentially arranged from top to bottom. A winding column 110 is arranged in the public warehouse 11, a plurality of sockets 120 are arranged in the socket warehouse 12, a network interface panel 131, a video interface panel 132 and a cylindrical magnet 133 are arranged in the panel warehouse 13. The upper part of the box body 1 is provided with a liquid nitrogen storage mechanism 3, the liquid nitrogen storage mechanism 3 includes a storage tank 31, the storage tank 31 is filled with liquid nitrogen, and the upper part of the st...

The invention discloses a multimedia box, and relates to an access network box. The multimedia box comprises a box body and a sliding door. A liquid nitrogen storage mechanism is arranged in the upper part inside the box body, and the liquid nitrogen storage mechanism comprises a storage tank filled with liquid nitrogen. Baffle plates, which can be opened and closed, are symmetrically arranged at the lower end of the storage tank, and an electronic inductive switch is arranged at the front end of each baffle plate. An air jetting device is arranged on the inner side face of the sliding door. Heat sensors are arranged on the side walls of the box body and the box door. A controller is arranged in a common bin. Compared with the prior art, by arranging the unique movable air-jetting fire extinguishing device and the liquid nitrogen storage mechanism in the multimedia box of the invention, a fire is extinguished first by high-pressure gas and then by liquid nitrogen, the phenomenon of short circuit of an optical fiber line caused by fire extinguishing by water is avoided, the fire extinguishing effect is good, the purpose of controlling fire and protecting equipment in the box body is achieved, intelligent fire extinguishing is realized, and the multimedia box is safe and practical.
Description
technical field [0001] The invention relates to an access network box body, in particular to a multimedia box. Background technique [0002] With the increasingly fierce competition in the telecommunications market, the existing broadband access construction model based on copper cables as the transmission medium and based on Asymmetric Digital Subscriber Line (ADSL) technology will not be able to adapt to the future development of high-speed high-speed video such as high-definition video and security monitoring. Bandwidth service requirements. As an effective measure to implement network transformation and fixed-line broadband, "fiber-in and copper-out" will play an important role in increasing access bandwidth, improving network support for services, and enhancing operators' core competitiveness. [0003] The multimedia box is a centralized box for weaker voltage lines. It is generally used in modern home decoration, such as network cables, telephone lines, and TV antenna...
