Abstract

The utility model discloses a tube shape fireproof lamp, which comprises a support board and a tube cover. The light source and the lamp holder are arranged in the tube cover, a through hole is arranged at the tube cover, and a pipe is arranged at the through hole, the wire of the connecting lamp holder passes through the pipe and is connected with the electrical appliance outside the trunk cover, the fireproofing material or/and the fireproof expending material are arranged in the pipe or near the incoming line of the pipe. Once the fire is breaking out, the fireproofing material or/and the fireproof expending material can prevent the fire from bursting out from the clearances, so as to prevent the fire from spreading around, therefore the utility model is safe and reliable.

Description

The tubular fire resistant lighting fitting

Technical field

The utility model relates to a kind of light fixture, particularly a kind of tubular light fixture with fire-proof function.

Background technology

A kind of tubular fire resistant lighting fitting is arranged, and it comprises that support plate and tube cover, and the tube cover is fixed on the support plate, and light source and lamp socket are installed in the tube cover, and a cover is provided with through hole, and conduit is installed on the through hole, and the electric wire that connects lamp socket passes conduit and is connected with the electrical equipment of tube cover outside.Because often have the gap between pipe inner wall and the electric wire, when breaking out of fire, the intensity of a fire will be emerged from these gaps, thus to around spread.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of tubular fire resistant lighting fitting that prevents fire spreading, safety effectively.

The technical scheme that its technical problem that solves the utility model adopts is: the tubular fire resistant lighting fitting, comprise support plate and tube cover, light source and lamp socket are installed in the tube cover, the tube cover is provided with through hole, conduit is installed on the through hole, the electric wire that connects lamp socket passes the outside electrical equipment of conduit and tube cover and is connected, it is characterized in that: the expanding material of preventing fires that in the conduit fire proofing material is installed or/and the incoming line of prevent fires expanding material or conduit is attached with fire proofing material.

As further improvement of the utility model, fire proofing material is installed the gap between described through hole edge and the conduit outer wall or/and the fire prevention expanding material.

As further improvement of the utility model, described through hole edge is provided with outside or inwardly protruded cavity, and conduit passes from cavity, is filled with fire proofing material between conduit and the cavity inner wall or/and the fire prevention expanding material.

As further improvement of the utility model, described fire proofing material or/and the fire prevention expanding material be enclosed in the cavity by compressing tablet.

As further improvement of the utility model, fire proofing material is installed the gap between described support plate and the tube cover or/and the fire prevention expanding material.

As further improvement of the utility model, be coated with fire proofing material on the plate face of described support plate or/and the fire prevention expanding material.

The beneficial effects of the utility model are: the fire prevention expanding material because the gap in the conduit, between through hole edge and the conduit outer wall is equipped with fire proofing material, when breaking out of fire, fire proofing material is or/and the fire prevention expanding material will stop the intensity of a fire to be emerged from these gaps, thereby prevent effectively the intensity of a fire to around spread, so the utility model uses safe and reliable.

The specific embodiment

See figures.1.and.2, the tubular fire resistant lighting fitting comprises support plate 1 and tube cover 2, light source and lamp socket are installed in the tube cover 2, and tube cover 2 is provided with through hole, and conduit 3 is installed on the through hole, the electric wire 5 that connects lamp socket passes conduit 3 and is connected with the electrical equipment of tube cover outside, and fire proofing material 4 is installed in the conduit 3.When breaking out of fire, fire proofing material 4 will stop the intensity of a fire to be emerged from these gaps, thus prevent effectively the intensity of a fire to around spread, so the utility model uses safe and reliable.

When having the gap between through hole edge and the conduit outer wall, fire proofing material 4 can be installed in the gap, thereby stop the intensity of a fire from these gaps, to be emerged.

With reference to Fig. 3, Fig. 4, to emerge in order to stop more effectively the gap of the intensity of a fire between through hole edge and conduit outer wall, described through hole edge is provided with the cavity to outer lug, and conduit 3 passes from cavity, is filled with fire proofing material 4 between conduit 3 and the cavity inner wall.Described fire proofing material 4 or be enclosed in the cavity by compressing tablet 9; Wherein, described compressing tablet 9 is fixed in the cavity.With this fire proofing material 4 is fixedly mounted in the cavity, prevents that it from coming off, further strengthen fire-proof function of the present utility model.Certainly, described cavity can be to convex (as shown in Figure 5).Compressing tablet 9 also can be fixed on the wall of cover 2 (as Fig. 6, shown in Figure 7) by screw.

When having the gap between support plate 1 and the tube cover 2, equally also fire proofing material 4 can be installed in these gaps, stop the intensity of a fire from these gaps, to be emerged, thereby further improve security performance of the present utility model.

For from improving security performance of the present utility model to the full extent, can on the plate face of described support plate 1, cover fire proofing material 4.

With reference to Fig. 8, in the time of in conduit 3 does not put in tube cover 2, can fire proofing material 4 be installed in the inside of conduit 3, installation just can reach the fireproof purpose near conduit 3 incoming lines.

Certainly, described fire proofing material 4 usefulness fire prevention expanding materials substitute, or use simultaneously with the fire prevention expanding material, and flameproof effect can be better.But the utility model is not limited to the above embodiments, utilizes technical characterictic of the present utility model to reconfigure the innovation and creation that form, and is equal to the utility model or becomes bad technical scheme also should belong within the protection domain of the present utility model.
