Description

The security door blind hinge

One, technical field

The invention relates to the hinge of using on a kind of security door, particularly a kind of blind hinge that can 180 ° of unlatching door leafs.

Two, background technology

Blind hinge commonly used generally can only make the door leaf unlatching not wait for 90 °-110 ° on the security door at present, when security door is installed the wall face external-open, tend to block passageway or corridor, bring great inconvenience for people's live and work because the reason of hinge can not be driven door leaf flatly.Be head it off, Chinese patent 02114737.X discloses a kind of " stealthy comprehensive door hinge ", it is provided with two rotating shafts on hinge bodies, can make door leaf open 180 °, and the door leaf after the unlatching can abut in the door frame side wall surface.But there is following defective in it, makes this hinge can not be applicable to present security door: the one, and the order that uncontrollable in use two rotating shafts of this kind hinge are successively rotated; Be equipped with the screening tape edge on the door leaf of existing security door, the rotating shaft of being located at when opening the door in the door leaf is rotated earlier or is rotated earlier in the rotating shaft of being located in the door frame at closing time, all can cause the screening tape edge and the door frame of door leaf inconsistent, makes door be difficult to open; The 2nd, the hinge up and down on the security door is asynchronous, is opening the door or can make door leaf distortion at closing time, when overexerting even can turn round bad door leaf or door frame, door can't be closed; The 3rd is that the gap of this kind hinge door leaf and door frame can't be adjusted, and brings inconvenience to production.

Three, summary of the invention

In order to overcome existing door leaf side rotating shaft and the rotating shaft of the door frame side disadvantage of order priority rotation in accordance with regulations, the invention provides rotating shaft of a kind of door leaf side and the rotating shaft of the door frame side security door blind hinge that order is successively rotated in accordance with regulations, unlatching is reliable, easy for installation.The invention solves the technical scheme that its technical problem adopts and comprises hinge bodies and door frame hinge seat, one end of hinge bodies links to each other with door frame hinge seat on being fixed on door frame by the door frame rotating shaft, the other end of hinge bodies is connected with the door leaf rotating shaft, the door leaf rotating shaft matches with the door leaf fixed axis, the door leaf fixed axis is arranged on the door leaf hinge seat, the door leaf hinge seat is fixed in the hinges fixing reservation of door leaf, and the hinge bodies of described door frame one side is provided with at least one permanent magnet.

Described door leaf fixed axis is provided with elastic device, and elastic device is provided in a side of the spring on the door leaf fixed axis, in the parts that an end of spring is positioned to link to each other with the door leaf rotating shaft, in the parts that the other end of spring is positioned to link to each other with the door leaf hinge seat.

Described hinge bodies is made up of door frame linkage section and door leaf linkage section, and the door frame linkage section is provided with screw, and the door leaf linkage section is provided with microscler adjustment hole, and is connected by firm, is convenient to the adjusting in crack between a door and its frame gap.

The permanent magnet that is provided with on the described door frame linkage section is preferably two, and permanent magnet distributes up and down, and suction is bigger, and it is more reliable to work.

After adopting said structure, the hinge of the invention can be controlled the order that two rotating shafts are successively rotated in use.When opening the door, because the flexible device of rotating shaft of door leaf side, make the rotating shaft twisting resistance of door frame side less than the twisting resistance of the rotating shaft of door leaf side, the rotating shaft of door frame side is rotated earlier, open 90 ° after, hinge bodies and door frame are inconsistent, the rotating shaft of door frame side stops operating, and this moment, the permanent magnet of hinge bodies was inhaled mutually with door frame, under the effect of opening force, the rotating shaft of door leaf side is rotated further 90 °, thereby makes door leaf open 180 °; At closing time, because the permanent magnet of hinge bodies is inhaled mutually with door frame and the restoring force of elastic device, the rotating shaft that can guarantee the door leaf side is rotated earlier, after the rotating shaft of door leaf side is rotated 90 °, door leaf and hinge bodies are inconsistent, the rotating shaft of door leaf side can't be rotated again, and this moment, door leaf continued to rotate 90 ° around the rotating shaft of door frame side under the effect of the power of closing; Chain two rotating shafts sequencing in accordance with regulations rotates, and can not cause door leaf screening tape edge and door frame inconsistent; Has simple in structure, advantage such as feel is light, easy to install, reliable operation.
