Description
One, technical field
The invention relates to a kind of metal hinge, particularly a kind of anti-force open the door or security door on the anti-blind hinge of forcing open the door that uses.
Two, background technology
The anti-blind hinge kind of using of forcing open the door is multifarious, varied now, use these blind hinges anti-force open the door or security door a common characteristic is arranged is that the angle of opening is all about 90 °, trace it to its cause, the one, be subjected to anti-forcing open the door or the influence of security door doorframe and door leaf structure, the 2nd, be subjected to the restriction of hinge arrangement.Can open the above back-flap hinge of 180 ° of angles although have on the market,, but exist the great defective workmanship that to install if be applied on the door with pick-proof limit; Shang Ruo is applied on the door that does not have the pick-proof limit, also need open mounting groove on door leaf and doorframe, otherwise the crack between a door and its frame gap is just big.This security door of installing with back-flap hinge exists easy sled, influences overall appearance and opening angle is subjected to shortcomings such as doorframe shape limitation.
Three, summary of the invention
In order to overcome existing anti-force open the door or security door can only be opened disadvantage about 90 °, the invention provides a kind of can conveniently make anti-forcing open the door or 180 ° of security door opening angles and above and do not influence the anti-blind hinge of forcing open the door of pick-proof effect.The invention solves the technical scheme that its technical problem adopts and comprises articulated mounting, this device comprises the doorframe holder, be fixed on the door-hinge on the doorframe holder, doorframe pivoted arm and the door leaf pivoted arm hinged with door-hinge, one end of door leaf pivoted arm is connected with the doorframe pivoted arm, and adjusting position mutually, described articulated mounting is provided with articulated mounting and following articulated mounting at least, the door leaf pivoted arm other end on this time articulated mounting is fixed with inserted block and first time inserted block on first, following turning cylinder is fixedlyed connected with first time inserted block, this time turning cylinder is arranged on down on the door leaf hinge seat, and can rotate relative to following door leaf hinge seat; The door leaf pivoted arm other end that should go up on articulated mounting is fixed with inserted block and second time inserted block on second, and last turning cylinder is fixedlyed connected with inserted block on second, and axle is rotationally connected under being fixed with between inserted block on adjacent first and the second time inserted block.After adopting said structure, there are two run-on points in this hinge, and one is arranged in the doorframe, and another is provided with in the door leaf, makes about 90 ° of the interior run-on point of doorframe and each rotations of the run-on point in the door leaf, thereby realizes that door leaf and doorframe relatively rotate about 180 °; Because it is fixedly connected between the articulated mounting up and down by the axle that is rotationally connected, thereby the mutual interference of two run-on points when having prevented the door opening and closing, make an opening and closing flexibly, conveniently, solve existing blind hinge and can only open 90 ° of defectives of being brought, have and open advantages such as more convenient, that the pick-proof effect is unaffected.

Five, the specific embodiment
Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, specific embodiments for a kind of anti-blind hinge of forcing open the door of the invention, it comprises articulated mounting, this articulated mounting comprises doorframe holder 8, be fixed on the door-hinge 12 on the doorframe holder 8, doorframe pivoted arm 11 and the door leaf pivoted arm 6 hinged with door-hinge 12, be provided with adjustment hole 10 at door leaf pivoted arm 6, door leaf pivoted arm 6 is fixing with doorframe pivoted arm 11 by adjustment hole 10 and hold-down screw 9, and by adjustment hole 10 mutual adjusting positions, described articulated mounting is provided with, in, following articulated mounting 19,23,26, door leaf pivoted arm 6 other ends on this time articulated mounting 26 are fixed with inserted block 25 and first time inserted block 3 on first, following turning cylinder 2 is fixedlyed connected by hold-down screw 91 with first time inserted block 3, this time turning cylinder 2 is arranged on down on the door leaf hinge seat 13, and can rotate relative to following door leaf hinge seat 13; Door leaf pivoted arm 6 other ends in being somebody's turn to do on the articulated mounting 23 are fixed with inserted block 30 and the 3rd time inserted block 31 on the 3rd; Door leaf pivoted arm 6 other ends that should go up on the articulated mounting 19 are fixed with inserted block 24 and second time inserted block 27 on second, and inserted block 24 is fixedlyed connected by hold-down screw 91 on the last turning cylinder 20 and second; The axle 16 and fixing by hold-down screw 91 that is rotationally connected under being connected with between inserted block 25 on adjacent first and the 3rd time inserted block 31 is being connected with the axle 17 that is rotationally connected down between inserted block 30 and second time inserted block 27 on the adjacent the 3rd, and is fixing by hold-down screw 91.
In order to reduce wear, be provided with lower bearing 15 on the following axle 16 that is rotationally connected between the inserted block 25 on the following hinge seat 13 and first, on middle hinge seat 28 and the 3rd between the inserted block 30 on the axle that is rotationally connected be provided with middle (center) bearing 29 on 17, on upper hinge seat 21 and second between the inserted block 24 on be provided with upper bearing (metal) 22 on the turning cylinder 20, certainly above-mentioned bearing also can be other rotors, as copper sheathing etc.
On the following turning cylinder 2 between following hinge seat 13 and the first time inserted block 3, be provided with time buckle 14, buckle 32 in being provided with on the following axle 16 that is rotationally connected between middle hinge seat 28 and the 3rd time inserted block 31, being rotationally connected at following between upper hinge seat 21 and the second time inserted block 27 is provided with buckle 18 on spools 16.
For convenient disassembly, with corresponding door leaf pivoted arm 6 of described inserted block and door leaf 1 on be provided with hole 5 outside dismounting endoporus 4 and the dismounting successively.
The invention generally be installed in anti-force open the door or security door on use, when opening the door, because the relation on pick-proof limit, run-on point in the doorframe is changeed about 90 ° earlier, along with the continuation of door is opened, the pick-proof limit of door leaf breaks away from the pick-proof point on the doorframe, and the run-on point in the door leaf can be rotated further about 90 ° again at this moment, thereby realize that door leaf and doorframe relatively rotate about 180 ° vice versa.Because fixedly connected by rotating up and down connecting axle 17,16 between the articulated mounting of upper, middle and lower, thereby the mutual interference of two run-on points when having prevented the door opening and closing, make an opening and closing flexible.
