Abstract

The utility model relates to a fireproof lifesaving door with an inward and outward opening function, which mainly solves the problem that a traditional fireproof lifesaving door has poor security, inconvenient use, etc. A main door body is pivoted and erected in a doorframe by utilizing a plurality of main pivot leaves, the board surface of the main door body has a frame hole with a suitable size, and an auxiliary door body of which the shape and the specification are corresponding to that of the main door body is assembled in the frame hole. The fireproof lifesaving door achieves the purpose of improving fireproof safety and use convenience by utilizing the characteristic that the main door body and the auxiliary door body respectively adopt a bidirectional opening design of opening inward and outward in different directions.

Description

Fire prevention escape with inside and outside open function

The utility model relates to the building door window construction, relates in particular to a kind of fire prevention escape with inside and outside open function.

In the building building now, based on antitheft, fire prevention and the turnover consideration that needs such as convenient, between its staircase and each floor or the external important channel place of building, generally all can be provided with suitable fire prevention escape, with the discrepancy that is convenient for people to, and take into account fire prevention, antitheft needs, so the importance of fire prevention escape is unquestionable.

The structure of the escape of tradition fire prevention at present as shown in Figure 3, its body 93 mainly is to utilize several pivot blades 94 in conjunction with being hubbed in the doorframe 90, the inner rim of this doorframe 90 is convexly equipped with the protruding edge 91 that supports that a circle abuts against for door body 93, can firmly recline when closing for door body 93 is positioned in the doorframe 90, to be used the door body 93 that needs and form a kind of inside unlatching or outwards open; In addition, based on the consideration of factors such as sound insulation and antiseepage, general doorframe 90 can be established a circle seal trim strip 92 with suitable shape lining at protruding edge 91 avris that body 93 abuts against of answering the door relatively that supports, and door body 93 appropriate locations can be provided with pressure handle 95 and badge tongue 96 etc., with keying and the clip location that is convenient to a body 93.

Brought forward is described, can not lock when the door body 93 of tradition fire prevention escape is flat, therefore, as long as the user depresses pressure handle 95 when indoor, just can make the badge tongue 96 of a body 93 withdraw from and door body 93 is opened, not only make things convenient for the user to pass in and out, and the effective utilization with fire prevention escape because door body 93 outsides do not have the design of similar pressure handle 95, except that utilize key operated, the stranger can't directly open from the outside with door body 93, can reach thief-proof, antitheft purpose; Improve part yet the structure design of tradition fire prevention escape still has not attain, therefore on use is implemented, have following shortcoming:

(1) lack appropriate safety Design: the door body 93 of at present traditional fire prevention escape all only has unidirectional open function, therefore, in case the opening direction of door body 93 is subjected to hoarding improperly foreign material or obstacle when stopping, door body 93 just only can be opened or can't be opened at all in the part, makes the fire prevention escape lose the purpose that is provided with of fire prevention escape fully; Certainly, foregoing problems perhaps can be alleviated slightly by keeping the unobstructed of door body 93 surrounding environment at any time, but when fire takes place, the masses tend to impact extrusion as a swarm of bees to fire prevention escape place, door body 93 very easily was subjected to clustering round pushing of the crowd and can't opens this moment, it is inner and be difficult to escape to make that the cluster people locks into a body 93 fully, and this is a big shortcoming of tradition fire prevention escape structure design.

(2) manipulate trouble inconvenience: based on fire prevention escape and antitheft consideration, tradition fire prevention escape only inboard are provided with pressure handle 95 and door body 93 can be opened, when people are positioned at a body 93 when outside, except utilize key operated, door body 93 can't be opened at all; Therefore, when people to attic or enter staircase, and when the door body 93 of the escape of will preventing fires is because of carelessness shut, other people assist except the request of raising a cry, the user can't open door body 93 at all, this phenomenon is trouble and the inconveniences of tradition fire prevention escape on manipulating, and believes that many people have this unhappy experience; Especially at present general fire prevention escape generally are provided with door check, and this phenomenon takes place more frequently.

Therefore, the inventor promptly only possesses unidirectional open function at above-mentioned tradition fire prevention escape, and the escape that cause preventing fires have the problem of inconvenience in the use, design the fire prevention escape with inside and outside open function of the present utility model.

It is a kind of simple in structure and have fire prevention escape of inside and outside open function that main purpose of the present utility model is to provide.

Further purpose of the present invention is to offer the suitable frame hole of specification in the plate face position of main door body, and the corresponding auxiliary door body of specification shape group established wherein, utilize the design of the inside and outside different opening directions of main Men Tiyu auxiliary door body employing, effectively improve the fire savety and the ease of use of fire prevention escape.

Fire prevention escape with inside and outside open function of the present utility model, include doorframe and main door body, this master's door body utilizes several main pivot blade pivots to be located in the corresponding doorframe, and the protruding of the architrave of main door body and doorframe abuts against to edge is relative, the plate face of main door body offers the suitable frame hole of specification, the corresponding auxiliary door body of specification shape then utilizes several secondary pivot vane group to be located in this frame hole, and the architrave that makes the auxiliary door body and frame hole inner peripheral protruding supports that edge is relative to be abutted against, and makes main Men Tiyu auxiliary door body have different opening directions respectively.

Characteristics of the present utility model are that it will lead a body 20 dexterously and be made as different opening directions respectively with auxiliary door body 30, because the functional design of this bidirectional opening, even when making a certain opening direction of fire prevention escape be subjected to hoarding improperly foreign material or obstacle to stop, the user still can will lead a body 20 or auxiliary door body 30 is opened towards the another one direction, effectively improve the Practical Benefit and the safety of fire prevention escape; Especially take place and the masses when pushing when fire in fire prevention escape place with swarming, user near fire prevention escape position, still can be easily will lead a body 20 or auxiliary door body 30 is pushed open outwardly, do not have the rough sledding that locks into fire prevention escape inside and take place, guarantee the common people's life security; Fire prevention escape with inside and outside double-direction starting function of the present utility model are safe and manipulate easy.
