Background technology

In the modern Interior finishing, be everlasting and some recessed light fixtures be installed on the local wallboard such as furred ceiling, Bao Qiang, family property, the intensity of a fire spreads when preventing that fire from taking place, what the wallboard in above place used all is fire-proof board, the top layer of fire-proof board is a fireprotection layer, and the intermediate layer generally all is flammable, needs perforate on PLASTIC LAMINATED when recessed light fixture is installed; fiery Slim is by the ignite intermediate layer of PLASTIC LAMINATED of recessed light fixture, and PLASTIC LAMINATED does not just play due anti-fire action yet; In case the inner ， Huo Slim that catches fire of recessed light fixture goes here and there out the interior combustible of pilot chamber then can cause the generation of fire.For effectively preventing the generation of above-mentioned situation, people improve the structure of recessed light fixture, but the fire protecting performance of existing embedded fire resistant lighting fitting all can not meet the demands, or only can accomplish to prevent in the outer fire introducing luminaire body of light fixture, or only can accomplish to prevent that fire in the luminaire body from going here and there out the outer facility of damage luminaire body, and can not accomplish to prevent that the outer fire of light fixture from introducing in the luminaire body, can accomplish again to prevent that the fire in the luminaire body from going here and there out.

Summary of the invention

The technical problems to be solved in the utility model is: solve existing embedded fire resistant lighting fitting and can not accomplish to prevent can accomplish the technical problem that prevents that the fire in the luminaire body from going here and there out again in the outer fire introducing luminaire body of light fixture.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of embedded fire resistant lighting fitting, shell with lamp body and tubular, the lamp body setting in the enclosure, shell aperture end top is provided with inner casing, inner casing is fixedlyed connected with shell, the main body of inner casing is a tubulose, the main body upper end has one along the locating ring of tube wall to the extension of pipe periphery, the bending downwards of locating ring periphery, the expansion type fireproof pad is housed between locating ring inner surface and ceiling or wallboard, and shell upper is fixed with an expansion type fire-protection ring along inwall.No matter be that lamp interior or outside have caught fire, expansion type fireproof pad and expansion type fire-protection ring are met heat and are expanded rapidly, the fire that stops the light fixture outside in light fixture and it are contained in ceiling or wallboard by or the fire of prevention lamp interior go here and there out the combustibles outside the light fixture of igniting, hold back spreading of back-fire relief.

Installation for ease of the expansion type fire-protection ring, can reach the purpose that makes fitting structure simple, easy to make again, firmly, the main body lower end of described inner casing has one along the base plate of tube wall to the tube hub extension, also be provided with the interior ring of step in the shell, in ring base plate is pressed between the upper surface of step surface and shell of ring, encircle in the top of expansion type fire-protection ring is arranged on and shell between, interior ring, expansion type fire-protection ring and shell riveted and fixed.

For preventing that moisture from entering lamp interior, be provided with the silicone rubber seal pad between described locating ring inner surface and expansion type fireproof pad.

Simultaneously can prevent that again moisture from entering the purpose of lamp interior for reaching more to change the bulb easily, described lamp body top is provided with interior card, interior card is made up of annular cover plate and collar, at least one elastic card claw is arranged at the collar bottom, the elastic card claw middle part is to outer lug, boss corresponding to elastic card claw on the main body of inner casing is provided with an annular groove, the annular cover plate of interior card covers on the lamp body upper surface, be provided with silicone rubber O-ring in the cavity between the step surface of the main body of lamp body and inner casing and interior ring, silicone rubber O-ring is realized the sealing between lamp body and inner casing, stop moisture to enter lamp interior from the gap location of lamp body and inner casing, as long as manage to take off interior card in the time of need more changing the bulb, as adopt hard sheet to insert between interior card cover plate and lamp body, and interior card is prized, just can change like a cork.

For ease of dismantling interior card, more easily more change the bulb, have the hole on the annular cover plate of described interior card, the tip utensil is inserted in the aperture, interior card is prized, just can more change the bulb like a cork.

Can securely lamp body be fixed in the enclosure for card in making, described elastic card claw is 2～5, and elastic card claw is along the collar circumference uniform distribution.

The beneficial effects of the utility model are, embedded fire resistant lighting fitting of the present utility model, panel in the fire that can stop the light fixture outside when the light fixture outside catches fire is contained in from light fixture and it passes through, and when lamp interior is caught fire, can stop the fire in the luminaire body to be gone here and there out, and simple in structure, more change the bulb conveniently.
