Description
Technical field
The utility model relates to a kind of hinge, the hinge that uses on particularly a kind of security door.
Background technology
At present the hinge that uses on the security door generally constitutes by portable plate and fixed head and with the fixing hollow bearing pin of portable plate, and portable plate and fixed head are by fixed screw fixedly on door leaf and the doorframe.Its weak point: the one, security door can only be opened about 90 °-110 °, should not be in the office space, dormitory, apartment, hotel etc. have the occasion in corridor to use.The 2nd, after security door dispatched from the factory, crack between a door and its frame uneven phenomenon in the left and right sides appearred, and when causing the security door switch dumb, the user just is difficult to oneself go to adjust the gap of left and right sides crack between a door and its frame, brings unnecessary trouble to the user, also brings harmful effect to enterprise simultaneously.
Summary of the invention
In order to overcome the above-mentioned disadvantage that existing security door hinge exists, the utility model provides a kind of door leaf can open 160 °-175 ° and can conveniently adjust the security door hinge in crack between a door and its frame gap.The technical scheme that its technical problem that solves the utility model adopts comprises door leaf fixed head, pivoted arm, described pivoted arm is the J font, the connecting hole hinged with doorframe is arranged on the gib head of pivoted arm J font, makes the certain distance H of door leaf fixed center wired-AND gate frame pin joint skew.
Adjust for the ease of left and right sides crack between a door and its frame, described door leaf fixed head is provided with fixed block, be provided with the slot that is complementary with fixed block in the described pivoted arm, fixed block is inserted in the slot, the end face of pivoted arm is provided with a slot at least, fixed block is provided with and the corresponding screw hole of slot, and holding screw is fixed on the screw hole of fixed block by slot.
More accurate in order to regulate left and right sides crack between a door and its frame, described pivoted arm is provided with adjustment seat, is provided with active screw in the adjustment seat, and the door leaf fixed head is provided with the adjusting support, and active screw is fixed on the screw hole of regulating support.
More firm for the door leaf fixed head is connected with pivoted arm, the side of pivoted arm is provided with a slot at least, and fixed block is provided with and the corresponding screw hole of slot, and holding screw is fixed on the screw hole of fixed block by slot.The bottom surface of pivoted arm is provided with tighten the screws.
After adopting said structure, because pivoted arm is the J font, the connecting hole hinged with doorframe is arranged on the gib head of pivoted arm J font, therefore can determine the distance H of door leaf fixed center wired-AND gate frame pin joint skew according to the thickness of door leaf, thereby make door leaf can open 160 °-175 °; Be connected by active screw between cooperation by fixed block and slot and adjustment seat and the adjusting support, make the adjustment of door leaf left and right door gap very steady, convenient; Have advantages such as simple and reasonable, that opening angle big, the crack between a door and its frame gap is easy to adjust, be connected firmly.

Fig. 2 is the A-A sectional structure schematic diagram of the utility model Fig. 1.
Fig. 3 is a backsight structural representation of the present utility model.
The specific embodiment
Fig. 1 is to shown in Figure 3, be the specific embodiments of the utility model security door hinge, it comprises door leaf fixed head 1, pivoted arm 2, pivoted arm 2J font, the connecting hole 10 hinged with doorframe is arranged on the gib head of pivoted arm 2J font, makes the certain distance H of door leaf fixed center wired-AND gate frame pin joint skew; Door leaf fixed head 1 is provided with fixed block 3, be provided with the slot 4 that is complementary with fixed block 3 in the pivoted arm 2, fixed block 3 is inserted in the slot 4, the end face of pivoted arm 2 is provided with two slots 5, fixed block 3 is provided with and slot 5 corresponding screw holes, and holding screw 6 is fixed on the screw hole of fixed block 3 by slot 5; Pivoted arm 2 is provided with adjustment seat 13, is provided with active screw 12 in the adjustment seat 13, and door leaf fixed head 1 is provided with regulates support 11, and active screw 12 is fixed on the screw hole of regulating support 11; The side of pivoted arm 2 is provided with two slots 8, and fixed block 3 is provided with and slot 8 corresponding screw holes, and holding screw 7 is fixed on the screw hole of fixed block 3 by slot 8; The bottom surface of pivoted arm 2 is provided with tighten the screws 9.
In actual use, at the door leaf of different-thickness, need to determine J font pivoted arm 2 arc diameters, guarantee the distance H of door leaf fixed center wired-AND gate frame pin joint skew, in door leaf is opened the angular range of stipulating, can not collide, thereby make door leaf can open 160 °-175 ° with doorframe.When needs are regulated the left and right door gap, unclamp holding screw 6,7 and tighten the screws 9 earlier, be rotatably provided in active screw 12 in the adjustment seat 13 with Allen wrench then, because pivoted arm 2 is hinged on the doorframe, therefore, can only move by regulating support 11 promotion door leaf fixed heads 1 when active screw 12 rotates, thereby reach the purpose of adjusting door leaf left and right door gap; And fixed block 3 is inserted in the cooperation in the slot 4, the gravitation energy of door leaf is delivered on the pivoted arm 2 by fixed block basically, therefore it is stressed more reasonable to regulate the active screw 12 of left and right door gap and holding screw 6,7 and tighten the screws 9, the left and right door gap is regulated more convenient, fixedly connected solid and reliable.
