Abstract

The utility model discloses a normally-open fireproof door, which comprises a doorframe arranged inside a wall, a door plate hinged to the doorframe, a door closer arranged between the doorframe and the door plate, and an electromagnetic coupling assembly connected between the free end of the door plate and the wall. Under normal conditions, the fireproof door is opened for pedestrians to pass through. During fire alarms or fire accidents, the fireproof door can be immediately closed so as to effectively avoid the fire propagation.

Description

Often open labeled door

Technical field

The utility model relates to the fire safety technical field, is specifically related to a kind of labeled door of often opening.

Background technology

Between the building fire protection subregion, usually labeled door need be set, the more frequent passage that passes through of someone is when the pedestrian is current at every turn; The power of closing that must overcome the labeled door door closer is firmly pulled; This not only lets the use of labeled door very inconvenient, and has quickened to shorten application life of labeled door because of continuous open and close, and more serious is; Also often occur passing through for ease and labeled door fixedly being opened by force; When fire took place, therefore labeled door can not in time close automatically, thereby had very serious fire safety hidden danger.

In addition, because existing labeled door is a normally off, people for ease sometimes; Utilize article such as cupboard that door is withstood; Make door be in open mode for a long time, even door closer is destroyed, cause labeled door forfeiture automatic closing function; When breaking out of fire, labeled door has just lost due fire separation effect.

The utility model content

To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of labeled door of often opening, and it is convenient to people and passes through, and has higher safety simultaneously.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

Often open labeled door, comprise the doorframe that is installed in the wall, be hinged on the door-plate on the said doorframe, the electromagnetism coupling assembling that is installed in the door closer between said doorframe and the door-plate and is connected said door-plate free end and between the walls.

Said electromagnetism coupling assembling includes one and is installed in electromagnet on the wall and corresponding with said electromagnet and be positioned at the free-ended door-plate of said door-plate and inhale iron.

This is often opened labeled door and also is provided with a controller, and said controller and electromagnet electrically connect.

Also be connected with power line and signal on the said controller and receive line.

This is often opened labeled door and includes two door-plates of splitting, and is provided with a door lock between said two door-plates.

Said door-plate free end bottom also is provided with a latch.

The beneficial effect of the utility model is:

1, under normal circumstances, the labeled door of the utility model can be convenient to the pedestrian and pass through in opened condition;

2, when meeting with fire alarm or fire, can close immediately, effectively avoid spreading of the condition of a fire.

Description of drawings

Fig. 1 is a kind of structural representation of often opening labeled door of the utility model;

Fig. 2 is the labeled door open mode sketch map of often opening shown in Figure 1.

The specific embodiment

Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing:

Like Fig. 1, shown in 2, be a kind of labeled door of often opening of the utility model, it comprises doorframe 5; Two door-plates 7; Doorframe 5 is installed in two between the walls, and two door-plates 7 are connected to doorframe 5 both sides through hinge 6, and is and splits shape; Be connected with a door closer 8 between the top rail of two door-plates 7 and doorframe 5 respectively, door closer 8 makes door-plate 7 possess the trend of inside rotation.

Door-plate 7 is equipped with an electromagnetism coupling assembling with between the walls; Be used to overcome the rotatory force that 8 pairs of door-plates of door closer 7 produce, make door-plate 7 be in open mode, this electromagnetism coupling assembling comprises that being positioned at door-plate 7 free ends one end of pivot center (just away from) is equipped with a door-plate and inhales iron 10; Corresponding with it; One electromagnet 9 is installed on wall, and two terminals of electromagnet 9 are connected on the controller 2 through lead respectively, and controller 2 is provided with power line and signal receives line 3; The lead of two electromagnet 9 and controller 2 is hidden in respectively in spool 1 and the spool 4, and electromagnet 9 can make door-plate 7 produce outside rotation trend under "on" position.

Under the normal condition, the moment that the moment that 9 pairs of door-plates of electromagnet 7 produce produces greater than 8 pairs of door-plates of door closer 7, so door-plate 7 is in opened condition; When meeting with fire alarm or breaking out of fire, fire signal is sent to controller 2, and controller 2 gives electromagnet 9 outages, and electromagnet 9 loses suction, and door-plate 7 cuts out under the effect of door closer 8.

In addition, for further convenient use, between above-mentioned two door-plates 7, also be provided with a door lock 12, the bottom of a door-plate 7 also is provided with a latch 11 therein.

The utility model above-mentioned often opens the door that labeled door not only can be applied to opposite opened, also can be applied to the door of single face opening type.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
