Abstract
The invention discloses a self-closed type fireproof door. The self-closed type fireproof door comprises a fireproof door frame, a fireproof door leaf and a controller, wherein the fireproof door leaf is connected with the fireproof door frame through fireproof hinges; a fireproof embedded lock is arranged between the fireproof door frame and the fireproof door leaf; a fireproof door closer is mounted between the upper part of the door leaf and the door frame; the controller comprises an inducting and detecting unit, a triggering switch, a driving unit, an alarming circuit and an information transforming and sending device; an electromagnetic door stopper is arranged on the outer surface of one side, opposite to the wall, of the fireproof door, and is electrically connected with the controller. Further improvements adopted by the invention lie in that an electromagnetic door stopper is arranged at the lower part of the door leaf; a double-spring door closer is adopted by the fireproof door closer; uneven waviness-shaped patterns are rolled and pressed in the outer surface of the fireproof door leaf. The self-closed type fireproof door disclosed by the invention is opened in normal times, can be automatically closed when a fire occurs, and has a certain acoustic insulation function.
Description
Technical field
The present invention relates to a kind of fire-fighting fire-proof door, be specifically related to a kind of fire door self-closing type.
Background technology
Fire resistant doorsets of the prior art include fire-proof door leaf, fireproof door frame and the fire-proof door closer being connected between fire-proof door leaf, fireproof door frame and fire monitoring detector. Making fire resistant doorsets be in normally off under the effect of fire-proof door closer, fire resistant doorsets are in normally off, to the daylighting of fire-fighting Stairs, ventilate all very unfavorable. And if these Stairs public passage that to be artificial abortion travel frequently over, the frequent unlatching of fire resistant doorsets, it will cause it damage or make shorten its service life. If it will be appreciated that normally closed fire-fighting fire-proof door can be made at ordinary times to be in normally open, and can close immediately when breaking out of fire, by highly beneficial.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is proposed to one can be normally opened or normally closed, repeatedly open the fire door self-closing type of life-span length.
The present invention is achieved through the following technical solutions technical goal.
Fire door self-closing type, including fireproof door frame, fire-proof door leaf and controller; Described fire-proof door leaf is connected with fireproof door frame by hinge of preventing fires; Fire prevention edge lock it is provided with between described fireproof door frame and fire-proof door leaf; Between described door leaf top and doorframe, fire-proof door closer is installed; Described controller includes sensing probe unit, triggering switch, driver element, warning circuit, information conversion and dispensing device; It thes improvement is that: a side external surface relative with wall on described door leaf is provided with electromagnetism door-inhale, and electromagnetism door-inhale is electrically connected with controller.
In said structure, described electromagnetism door-inhale is arranged on door leaf bottom.
In said structure, described fire-proof door closer adopts dual spring door closer.
In said structure, described fire-proof door leaf outer surface roll-in has the corrugated decorative pattern of high low head.
The present invention compared with prior art, has the positive effect that:
1. door leaf is installed electromagnetism door-inhale, is electrically connected with controller, it is generally the case that fire resistant doorsets are adsorbed on wall by electromagnetism door-inhale, and fire resistant doorsets are in normally open; When controller finds fire condition by sensing probe unit, controller is to sending signal, and electromagnetism door-inhale power-off, thus the captivation that loses magnetism, fire resistant doorsets are closed under fire-proof door closer effect, cut off burning things which may cause a fire disaster.
2. fire-proof door closer adopts dual spring door closer, strengthens the stable performance of spring, increases the use fatigue strength of door closer, further enhances fire resistant doorsets service life.
3. the roll-in of fire-proof door leaf outer surface has the corrugated decorative pattern of high low head, compared with smooth outer surface, can play certain sound-absorbing and the effect stoping sound wave repeatedly to reflect.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Below according to accompanying drawing and the invention will be further described in conjunction with the embodiments.
Fire door self-closing type shown in accompanying drawing, including fireproof door frame 1, fire-proof door leaf 2 and controller 7; Fire-proof door leaf 2 is connected with fireproof door frame 1 by hinge 5 of preventing fires; Fire prevention edge lock 4 it is provided with between fireproof door frame 1 and fire-proof door leaf 2; Being provided with fire-proof door closer 3 between door leaf 2 top and doorframe 1, in the present embodiment, fire-proof door closer 3 adopts dual spring door closer; Controller 7 includes sensing probe unit, triggering switch, driver element, warning circuit, information conversion and dispensing device; The bottom of a side external surface relative with wall on door leaf 2 is provided with electromagnetism door-inhale 8, and electromagnetism door-inhale 8 and controller 7 are electrically connected.
Fire-proof door leaf 2 outer surface roll-in has the corrugated decorative pattern of high low head.
