Abstract
The utility model relates to a metal anti-theft door, which comprises a door leaf and a door frame which are connected together through invisible hinges. A fan-shaped bulge is arranged on the further edge of the door leaf, and a concave seat which corresponds to the fan-shaped bulge of the door leaf is arranged on the door frame. When a door is closed, the fan-shaped bulge of the door leaf enters into the concave seat of the door frame. A magnet and ferromagnetic materials which are mutually matched with each other are arranged in a fan-shaped bulge core space of the door leaf and the concave seat of the door frame, wherein, the fan-shaped bulge core space corresponds to the side provided with a door lock; the concave seat of the door frame corresponds to the fan-shaped bulge of the door leaf. The anti-theft door with a small door slot is difficult to prize, which causes an illegal prizer to have no chance to enter. The utility model has the advantages of favorable anti-theft performance, favorable sealing effect, favorable sound insulation effect, legerity, invisible hinges, and beautiful appearance. Furthermore, because of magnetic force adsorption, a door is fixed automatically when the door lock does not need locking, which can prevent external force, such as wind force, etc. from pushing the door open.
Description
The utility model relates to a kind of door, particularly a kind of metal anti-theft door that is made of door leaf and doorframe.
The metal anti-theft door of external-open generally is to weld iron hoop on door leaf and doorframe, play the hinge effect with the bar tip as rotating shaft, door leaf is that right angle or circle are opened the edge, because door leaf has certain thickness, junction between door leaf and the doorframe need have certain slit could realize opening, this crack between a door and its frame is given illegally to force open the door provides convenience, thereby theftproof performance is poor, also not attractive in appearance.
The purpose of this utility model is to provide the metal anti-theft door that a kind of crack between a door and its frame is little, theftproof performance is strong.
For achieving the above object, metal anti-theft door of the present utility model comprises door leaf 11, doorframe 12, door leaf 11 and doorframe 12 are connected by blind hinge, door leaf 11 outer rims have fan-shaped projection 13, doorframe 12 has the fan-shaped projection 13 corresponding dimples 14 with door leaf, at closing time, the fan-shaped projection 13 of door leaf enters in the dimple 14 of doorframe.
Above-mentioned blind hinge 15 can be made of page or leaf sheet, two limit page or leaf sheets and two rotating shafts in one, middle page or leaf sheet 5 is by rotating shaft 3 and rotating shaft 4 difference fillet page or leaf sheet 1 and limit page or leaf sheets 2, middle page or leaf sheet 5 and limit page or leaf sheet 1, limit page or leaf sheet 2 all are " U " shape structures, form a cavity at hinge closed condition following page or leaf sheet 1 and limit page or leaf sheet 2 subtends, middle page or leaf sheet 5 is arranged in this cavity.
Above-mentioned door leaf has magnet 17 and the ferromagnetic material 18 that cooperatively interacts at fan-shaped projection inner chamber that door lock one side is installed and corresponding doorframe dimple thereof.
Metal anti-theft door crack between a door and its frame of the present utility model is little, and difficulty is pried open, and the person that illegally do not force open the door is had no exploits, and theftproof performance is good; Sealing, compartment is effective; Can't see hinge, attractive in appearance light and handy; At closing time because magnetic force absorption is fixing automatically in the time need not locking, prevent that external force such as wind-force from pushing door open.
Fig. 1 is the utility model metal anti-theft door sectional view;
Fig. 2 is the utility model metal anti-theft door blind hinge closed condition front view;
Fig. 3 is the utility model metal anti-theft door blind hinge closed condition A-A sectional view;
Fig. 4 is the utility model metal anti-theft door blind hinge closed condition B-B sectional view.
Metal anti-theft door shown in Figure 1 has door leaf 11, doorframe 12, door leaf 11 is connected by 2-3 blind hinge 15 with doorframe 12, the outer rim of door leaf has fan-shaped projection 13, the fan-shaped projection 13 corresponding fan-shaped dimples 14 of doorframe and door leaf, and blind hinge 15 relative another sides have door lock 16.Above-mentioned blind hinge 15 is to adopt by three page or leaf sheets and two hinges that rotating shaft is formed, as disclosed three folding blind hinge or the disclosed Built-in hinges of Chinese utility model patent CN88204873U of Chinese utility model patent CN86200483U.Because use Built-in hinge, the fan-shaped projection of door leaf can strengthen thickening, can make radius and be 10 millimeters fan-shaped projection, reach higher intensity, strengthened the pick-proof performance effectively, crack between a door and its frame is less than 1 millimeter at closing time, can't see hinge again, so both attractive in appearance, the person that illegally do not force open the door is had no exploits.Also have ferromagnetic powder 17 in the fan-shaped projection 13 on the door leaf limit that door lock 16 is arranged, corresponding doorframe dimple has iron plate 18 (if doorframe is iron, can not add iron plate).In the time of need not locking closing the door like this,, prevent that external force such as wind-force from pushing door open because magnetic force absorption can fix automatically.
The middle page or leaf sheet 5 of blind hinge shown in Figure 2 is connected page or leaf sheet 1 and limit page or leaf sheet 2 respectively by rotating shaft 3 and rotating shaft 4, limit page or leaf sheet 1 and limit page or leaf sheet 2 are " U " shapes, middle page or leaf sheet 5 as shown in Figure 3, it also is " U " shape, rotating shaft 3 and rotating shaft 4 two ends are separately fixed at " U " shape inwall of limit page or leaf sheet 1 and limit page or leaf sheet 2, middle page or leaf sheet 5 connects two rotating shafts by two straight end limits, the width of limit page or leaf sheet as shown in Figure 4, under the hinge closed condition, in page or leaf sheet 5 be positioned at the cavity that " U " shape limit lamellar of two subtends becomes, the setting of spring 6 is that the corner between page or leaf sheet 5 and the limit page or leaf sheet 2 is excessive and may damage the fan-shaped projection 13 of door leaf in stoping.Use this blind hinge, in " U " shape inner chamber of page or leaf sheet 5, opened at realization 180 degree angles during the fan-shaped projection 13 of door leaf entered when opening the door.
