Embodiment

[0040] Such as figure 1 , figure 2 A kind of fireproof cover shown, it comprises cover top 1, hypotenuse 2, cover surround 6 and cover skirt 9, is provided with the cooling fin that is made of lower expansion material sheet 8 and upper layer ceramic fiber paper 4 on the hypotenuse, this The heat sink is installed on the hypotenuse by rivets 13, and the heat sink is provided with a plurality of air holes 3, one of which is a threading hole 5. The inside of the cover enclosure is provided with an inner cover support frame 14, and the cover top, beveled sides, cover enclosure and cover skirt are sewn from glass fiber cloth material with a fireproof paint layer on one side and a temperature resistance > 750°C. It can be seen that there is a sewing line 11) between the hypotenuse 2 and the enclosure 6 to make it resistant to temperatures >750° C. and form a closed cylinder. Two metal mounting brackets 10 are installed on the two ends of the fireproof cover by rivets 13, and the...

Abstract

The present invention provides a fire-resisting cover which can be used in electric portion of lighting installation and can be used for resisting fire propagation and quickly extinguishing flame and its heat sink special-purpose expansion material. Said fire-resisting cover includes cover top, oblique edge, cover enclosure and cover skirt, on the oblique edge the heat sink can be set, said heat sink is formed from lower layer of expansion material and upper layer of ceramic fibre paper, said expansion material is made up by using ceramic fibre, swelling graphite and polyvinyl alcohol as main raw material. The cover top, oblique edge, cover enclosure and cover skirt are made up by using high-temperature resisting glass fibre fabric whose one side is coated with fire-resisting coating layer.

Description

technical field [0001] The utility model relates to a protective device for lighting appliances and a special expansion material for heat sinks thereof, in particular to a fireproof cover for the electrical part of lighting fixtures and a special expansion material for heat sinks thereof. Or the burning caused by the electric spark igniting the surrounding flammable materials caused by poor contact can prevent the fire from spreading rapidly, causing the flame to extinguish itself due to lack of combustion conditions. Background technique [0002] In the existing decoration, the tail and electrical parts of lighting fixtures (including wiring parts and electrical accessories such as rectifiers, transformers, triggers, capacitors, etc.) are usually hidden behind panels (such as ceiling panels, wall panels, etc.) Once the wires or electrical components are short-circuited or poorly contacted to generate electric sparks, it is easy to ignite the flammable materials around the e...
