As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described door frame is provided with the rectangle hinge holding tank of opening to the right, is provided with rotating shaft and hinge in the groove.Hinge is built in the door frame, and overall appearance is good.
One end of described hinge is provided with the rotating shaft connecting portion, and the hinge other end is provided with backward the door leaf fixed edge of bending, and the door leaf fixed edge of hinge and the hinged limit of door leaf between forward and backward pick-proof portion are affixed.The hinged limit of door leaf makes the connecting portion of hinge and door leaf built-in between forward and backward pick-proof portion, be beneficial to antitheft, and flat appearance.
Described hinge is a split-type structural, the linking arm that it comprises the pivoted arm of establishing the rotating shaft connecting portion and is provided with the door leaf fixed edge.Hinge is a split-type structural, is convenient to the installation and the production of hinge.
Described pivoted arm be " [" shape pivoted arm, it comprises front, back and the company limit that is connected with forward and backward limit left end, to being bent to form bending edge, the bending edge end is provided with the rotating shaft connecting portion to transfer with rotating shaft to the front right-hand member of described pivoted arm to the right back.The company limit of pivoted arm is positioned at the left end on forward and backward limit, avoids pivoted arm in rotating counterclockwise process, and Lian Bian and door frame etc. are inconsistent.
Described linking arm is
The shape linking arm, it comprises front and the door leaf fixed edge vertical with the front.The front is used for being connected with the back of pivoted arm.
Described pivoted arm back is connected with the linking arm front by the mode of screw or welding.
Described pivoted arm, linking arm are section bar or by the sheet material press forming.Can when ensuring the quality of products, enhance productivity.
Described door frame front end is provided with the arc confined planes with restriction door leaf corner.Avoid because of hinge and impaired outward appearance and the functional performance of influencing of door frame collision.
Beneficial effect: under the state of closing the door, before the door leaf, back pick-proof portion embed respectively door frame before, in the back anti-pry notch, the sideshake of anti-pry notch and preceding pick-proof portion before the pry that the burglar uses need be introduced into, the bottom clearance of anti-pry notch and preceding pick-proof portion before entering again, because the existence of bending, anti-pry notch bottom before making tool used in crime be difficult to insert, and preceding pick-proof portion is prized, the problem of having avoided the burglar to commit theft in the mode of sled group crack between a door and its frame, on the basis of establishing the back anti-pry notch, increase preceding anti-pry notch, reached dual tamper-resistant function, further improved the theftproof performance of security door.
