Abstract
The utility model provides a novel burglary-resistant door, which comprises a door leaf and a door case, with an outer flange and an inner flange on the vertical edge of the door leaf.. The cross section of the outer flange is in trapezoid or V shape; the cross section of the inner flange is in trapezoid or V shape, or in right angle platform shape, with a groove or right angle platform fitted to the inner and outer flanges at an appropriate position.. The utility model is simple in structure and difficult to pry with a prying tool, with duplex protection function, and will not deform in case of prying; therefore, the user can open the lock easily even the door was subject to prying. The utility model is safe and reliable.. The utility model is applicable to environments where a burglary-resisting door must be used, such as home, hotel, office, or store room, etc..
Description
Technical field
The utility model relates to a kind of antitheft metal door, particularly relates to a kind of novel anti-forcing open the door.
Background technology
The pick-proof edge protection of existing antitheft metal door is to be extended to the door leaf direction by common antitheft metal door outer surface edge to constitute, or increases groove in the doorframe relevant position, though certain pick-proof effect is arranged, effect is undesirable.Chinese patent CN24233990Y discloses a kind of novel pick-proof shutter limit, is made up of door leaf outer rim edge protection and the doorframe fitting face that is mated.There is flanging the edge protection end, and the doorframe corresponding positions is equipped with the groove that cooperates with flanging.Flanging and door leaf surface are 60～90 ° of angles, and the cross section of flanging is a rectangle, and the groove on the doorframe is a swallow-tail form.Because the edge protection invagination forms flanging, embeds at closing time in the groove of doorframe, pry is difficult to insert in the edge protection, has certain pick-proof sled effect.But when pry is forced to pour, after the flanging distortion can and the interlocking groove form the locking state, under this state the householder unblank very inconvenient.And can only open the back at door lock and could remove this locking state, use inconvenience by applying external force.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of simple in structure, novel anti-the forcing open the door that pick-proof is effective and safe in utilization.
Novel anti-the forcing open the door of the utility model comprises that door leaf and doorframe, the vertical outer edge of door leaf have two flanges, the doorframe corresponding positions be equipped with cooperate with flange fitting face, wherein, two flanges are outward flange and inward flange.Outward flange be form after the bending of door leaf covering of the fan to outer lug, its cross section is trapezoidal or V-arrangement, with right-angled trapezium for well.Inward flange can be to be the inward flange of trapezoidal or V-arrangement to outer lug and cross section, also can be that cross section is the inward flange of right angle mesa-shaped.On the former the doorframe relevant position groove that cooperates with inward flange is arranged, the right angle platform that cooperates with inward flange is arranged on latter's doorframe relevant position.
The novel anti-operating principle of forcing open the door of the utility model is that the outward flange on the back door leaf of closing the door embeds in the groove of doorframe, matches in the groove on the inward flange embedding doorframe or with the right angle platform.
The novel anti-advantage of forcing open the door of the utility model is simple in structure, and pry is difficult to insert, and has double protection functions, and when external force is dashed sled, can not cause by locking, but householder's easy for unlocking still is safe and reliable.Be applicable to that family, hotel, office, storeroom etc. need install the occasion of security door everywhere.
