Description

Multifunction safety door

The utility model belongs to the door leaf technical field.

The outer door of building resident family mostly is wooden hollow core flush door at present.This door impact resistance is little, can not prevent fires, and insulation, sound insulation, theftproof performance are poor.

The multifunctional safe door that the purpose of this utility model is design a kind of fire prevention, insulation, sound insulation, theftproof performance is strong.

The utlity model has framework, be fixed on internal hilar plate and external door panel on the framework, be filled with cystosepiment in the interlayer of internal hilar plate and external door panel, one side of framework is fixed with simple insurance door lock and dual fail-safe door lock, opposite side is fixed with the rotating shaft loose-leaf, framework is made by square steel pipe, and internal hilar plate and external door panel are made of calcium-plastic board.

Because inside and outside door-plate of the present utility model is made by calcium-plastic board, so have fireproof performance, simultaneously, the cystosepiment of filling in the inside and outside door-plate, insulation, the sound insulation value of this utility model have been strengthened, in addition, the framework that square steel pipe is made and the dual fail-safe door lock of employing make this utility model have stronger anti-theft feature.

Accompanying drawing has provided embodiment of the present utility model, and wherein Fig. 1 is an overall structure schematic diagram of the present utility model, Fig. 2 be A among Fig. 1 to partial view, Fig. 3 is the B-B face sectional view among Fig. 1.(1) is the dual fail-safe door lock among the figure, and (2) are the simple insurance door lock, and (3) are external door panel, and (4) are cystosepiment, and (5) are framework, and (6) are internal hilar plate, and (7) are the rotating shaft loose-leaf.

In the present embodiment, framework (5) is welded by square steel pipe, be coated with rustproof paint outward, its side is by intrinsic simple insurance door lock of steel plate (2) and dual fail-safe door lock (1), opposite side is fixed with loose-leaf (7) with tapping screw, internal hilar plate (6) and external door panel (3) are made by calcium-plastic board, are fixed on the framework (5) with tapping screw, are filled with rigid foam plate (4) in the interlayer between internal hilar plate (6) and the external door panel (3).

When the utility model uses, loose-leaf (7) is fixed on the vertical beam of doorframe, simple insurance door lock (2) and dual fail-safe door lock (1) match with locked groove on being arranged on another vertical beam of doorframe, there is man-hour can only use simple insurance door lock (2) among the manager, then use dual fail-safe door lock (1) when going out, add the framework (5) of steel work, play antitheft effect, simultaneously, the internal hilar plate (6) and the external door panel (3) that adopt calcium-plastic board to make have fire-proof function, the rigid foam plate of filling has better sound insulation in the interlayer between internal hilar plate (6) and the external door panel (3), heat-insulating property, thus make the utility model possess fire prevention, sound insulation, insulation, multiple function such as antitheft.

Claims (3)
