Abstract

The utility model discloses a fire-proof lamp shade, which belongs to the field of building fire-protection devices. The fire-proof lamp shade comprises a fire-proof shade and a positioning rack supporting the fire-proof shade, wherein the fire-proof shade takes a shape of a complete cone; a hook used for hanging a transformer for a lamp is arranged on the outer side of the fire-proof lamp shade, and is integrally connected with the positioning rack at the upper end of the positioning rack; the thickness of the lower edge of the fire-proof shade is 20 to 40 mm; the fire-proof lamp shade has the properties of heat preservation and insulation due to thickened lower edge of the fire-proof shade to improve the weak fire-proof link of the fire-proof shade and enhance the fire prevention performance; the design enhances the refractory limit of the fire-proof lamp shade by extending the refractory limit of the fire-proof lamp shade over 2 hours; in the fire-proof lamp shade, the transformer for a lamp can be hung outside of the fire-proof lamp shade, so as to prevent heat generated by the transformer from accumulating in the shade, thereby further guaranteeing safety.

Description

Fireproof lampshade

Technical field

The utility model relates to a kind of lampshade, particularly a kind of fireproof lampshade.

Background technology

Modern architecture is used the more and more of ceiling furred ceiling, and various ornament lamps and a kind of especially inexorable trend of illuminating lamp are installed in perforate on ceiling.But this will bring bigger disaster hidden-trouble: on the one hand, the low-voltage energy-saving lamp transformer works long hours, if heat radiation is bad, and energy accumulation, temperature rises, and easily causes appliance fire; On the other hand, the fire endurance of ceiling furred ceiling is at least greater than 1 hour, and still, the fire resistance of low-voltage energy-saving lamp does not reach requirement.In case breaking out of fire, flare will be scurried the upper space of ceiling by the installing hole of low-voltage energy-saving lamp, thereby form stack effect, and the intensity of a fire heightens, and causes bigger destruction.

In order to address this problem, must design a kind of fire safety cover, under normal operating position, the thermal accumlation that does not cause low-voltage energy-saving lamp and transformer thereof to produce causes local temperature too high, initiation fire; But when fire took place, the fire safety cover can expand rapidly again, tightly covered on the installing hole of lamp, formed adiabatic sealant, blocked the installing hole of low-voltage energy-saving lamp, and the upside that stops flame to scurry ceiling by installing hole effectively causes bigger harm.

Application number is 2007100492311, denomination of invention is the Chinese patent of " fire proofing material, flameproof enclosure, fireproof lampshade and preparation method thereof ", reported a kind of fireproof lampshade, this fireproof lampshade is in order to adapt to thermal light sources such as incandescent lamp and electricity-saving lamp and design, on the lampshade wall, have air vent, to avoid thermal accumlation; In addition, other local consistency of thickness of the thickness of the lower edge of this fireproof lampshade and flameproof enclosure, be generally about 10mm, and in flammability test and fire practice, find that the lower edge of flameproof enclosure and the contact position of ceiling are weak link, flame at first sees through from this, so such structure is easy to make flame to see through from the lower edge of flameproof enclosure, causes fire.

Along with the development of modern technologies, high-power cold light source such as LED will progressively replace former thermal light source, be used for illumination and building decoration, and need ceiling to have better heat insulating effect and fire protecting performance.And the fireproof lampshade that application number is 2007100492311, denomination of invention is reported for the Chinese patent of " fire proofing material, flameproof enclosure, fireproof lampshade and preparation method thereof ", in order to dispel the heat, on flameproof enclosure, be provided with air vent, this just is unfavorable for insulation, and the structural representation of this lampshade is referring to accompanying drawing 1.

The utility model content

Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of development that can adapt to new lighting engineering, have heat insulating effect again, can also improve the fireproof lampshade of fire protecting performance simultaneously.

The technical solution adopted in the utility model is such: a kind of fireproof lampshade, the locating rack that comprises flameproof enclosure and support flameproof enclosure, described flameproof enclosure is complete taper, and be provided with a hook that is used to hang lamp transformer in the described flameproof enclosure outside, described hook is connected as a single entity with locating rack in the locating rack upper end.

As preferred version: described flameproof enclosure is complete coniform, and the lower edge thickness of flameproof enclosure is 20-40mm.

As further preferred: described flameproof enclosure lower edge thickness is 20mm.

In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:

Because flameproof enclosure is complete cone, no air vent more helps insulation, owing to adopt the LED cold light source, this structure can not cause the accumulation of heat.

The lower edge of flameproof enclosure is done thickening and is handled, and flameproof enclosure fire prevention weak link is improved, and has improved fire protecting performance, and this design has improved the fire endurance of fireproof lampshade, and the fire endurance that makes fireproof lampshade was above 2 hours.

The outside design of the locating rack of this fireproof lampshade upper end, flameproof enclosure is useful on the hook that hangs lamp transformer, and lamp transformer is hung over the outside of fireproof lampshade, avoids transformer to produce heat and accumulates in lampshade, has further guaranteed safety.

Description of drawings

Fig. 1 is the structural representation of the existing fireproof lampshade in the utility model background technology;

Fig. 2 is the structural representation of the utility model embodiment 1.

Mark among the figure: 1 is flameproof enclosure, and 2 is locating rack, and 3 are hook, and 4 is the flameproof enclosure lower edge, and 5 is connecting pin, and 6 is link, and 7 is air vent.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is done detailed explanation.

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Embodiment 1:

As shown in Figure 2, a kind of fireproof lampshade, the locating rack 2 that comprises flameproof enclosure 1 and support flameproof enclosure 1, locating rack 2 upper ends are passed flameproof enclosure 1 and are connected with the link 6 of flameproof enclosure 1 outer shape coupling, and be connected with a connection pin 5 in flameproof enclosure 1 lower end, this connecting pin 5 is used for being connected such as ceiling with extraneous, flameproof enclosure 1 is complete coniform, be provided with a hook 3 that is used to hang lamp transformer in flameproof enclosure 1 outside, hook 3 is connected as a single entity in locating rack 2 upper ends and locating rack 2, the thickness of flameproof enclosure 1 main body is 10mm, and the thickness of flameproof enclosure lower edge 4 is 20mm.

Because flameproof enclosure 1 is complete cone, no air vent 7 more helps insulation, owing to adopt the LED cold light source, this structure can not cause the accumulation of heat; Flameproof enclosure lower edge 4 is done thickening and is handled, and flameproof enclosure 1 fire prevention weak link is improved, and has improved fire protecting performance, and this design has improved the fire endurance of fireproof lampshade, and the fire endurance that makes fireproof lampshade was above 2 hours; The design of locating rack 2 upper ends of this fireproof lampshade, the outside of flameproof enclosure 1 is useful on the hook 3 that hangs lamp transformer, and lamp transformer is hung over the outside of fireproof lampshade, avoids transformer to produce heat and accumulates in lampshade, has further guaranteed safety.
