Description

Safe door

The utility model belongs to a kind of portable closing device of using at the opening part of building.Specifically relate to be installed in the metal door frame that plays protective action of wooden doorframe front side of wall upper shed place and the collapsible wing that its periphery connects.

The life dwelling environment of safety is people's basic psychology requirement.What but each gate, unit in most resident's buildings in city also still adopted at present is singly to fan the wooden door and the doorframe of rotating opening inwards.As everyone knows, it is very difficult coming anti-riot, antitheft with such door.At the thin and brittle weakness of above-mentioned door leaf, the someone adopts door leaf outer package iron sheet to reinforce.Though can increase the intensity of certain door leaf like this, not eliminate the possibility that heavily crashes through door yet.In order to address the above problem, disclosing a kind of application number in the Chinese patent gazette on October 19th, 1988 is 88203602 " security door ".Formation is at the iron bar fence gate that an outside rotating opening of single fan is installed on the wooden doorframe and is provided with the interlocking latch between inside and outside door.Weak point be the iron grid door of the outside rotating opening of single fan be used for the unit building can influence other people come in and go out corridor, stair activity with and bright loose-leaf ease of connection pry open etc.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of to be applicable to that protection singly fans the rotating opening wooden door and that be convenient to install inwards safety door.

The purpose of this utility model can realize by following structure: safety door comprises doorframe and plug-type folded metal fence door leaf and other annexes and syndeton that shapes such as the employing channel-section steel be made up of frame, lintel and threshold or angle steel are made.Special feature of the present utility model is that the profile of the profile of metal door frame and the wooden doorframe of single fan that wall upper shed place need be protected is overlapping.The back base plate of the metal door frame rear side corresponding with wooden doorframe front side or angle steel doorframe rear side welding is provided with screw or the bolt hole that can be directly be connected by screw or bolt with wooden doorframe front side.Also can be provided with on the metal door frame outside of side or the doorframe bottom portion of groove within the walls at corresponding door opening can be by expansion bolt or cement nail and the door opening side bolt or the cement nail hole of fixedlying connected within the walls.Can weld between the frame of doorframe and lintel and the threshold or be connected by bolt or eye-splice overlap joint.Plug-type folding fence door leaf can be designed between the vertical wire netting to intersect active of the hinged metal of rivet and vertically the fence upper/lower terminal can also can be designed as by the hinged rhombus cell structure of forming of metal gate sheet by lintel and threshold cavity guiding and position limiting structure.Special feature of the present utility model is that also doorframe that Men Bianwei that the open side rivet of folding fence door leaf is articulated and connected can insert channel-section steel or angle steel shape opens the strip steel plate or the shapes such as channel-section steel or angle steel of the front rear side of frame.In the groove of opening frame, be fixed with lockhole and open frame built-in lock in front perpendicular to opening the frame front or being parallel to.The two-way lock tongue of built-in lock can be opened the lock ring or the dead bolt hole sealing that are provided with on the unlatching door limit of frame front rear side with insertion and cooperate.In like manner, built-in lock also can be fixed in the rear side of opening the door limit, and its dead bolt cooperates with the lock ring of opening the interior setting of frame groove or dead bolt hole sealing.Be parallel to unlatching frame built-in lock in front for lockhole, can be provided with in the corresponding lockhole of a unlatching door limit rear side position and reveal the built-in lock protective cover that lockhole is arranged.Special feature of the present utility model also is can be respectively equipped with bearing pin and pin bearing syndeton between the upper/lower terminal of another frame of doorframe that folding fence door leaf opposite side rivet is articulated and connected and lintel and the threshold end.For the vertical fence upper/lower terminal of realizing folding fence door leaf can by lintel and threshold cavity guiding and when spacing the fence door leaf still can rotate around bearing pin, special feature of the present utility model is that also the cotter pin axle place, middle part, front of lintel and threshold disconnects and can separate with its bottom land and fixedly connected with the end of bearing pin frame.Also can and be respectively equipped with the articulated structure of flexible connection separately between the bottom land in the front of lintel and threshold, each left part, front is provided with the plate that can be connected with unlatching frame fixed limit by screw or latch.Also can make the front of lintel adopt one of said structure, and being designed to an end, threshold fixedlys connected with bearing pin frame lower end, cotter pin axle place, (the frame lower end is established supporting construction in addition) threshold middle part is provided with and can makes the threshold other end peg graft spacingly with opening frame lower end camber line, can make the part threshold rotate the articulated structure that lifts.
