The technical solution of the utility model is: a kind of hinged safety device of security door that can secondary changes door leaf opening angle, comprise a U-shaped hinge component, this hinge component comprises door leaf hinge and door frame hinge, described door leaf hinge and door leaf connecting place are provided with hinged safety device, this hinged safety device is flush-mounted on door leaf, comprises that can make door leaf open is greater than the spring buffer mechanism of changing buffer starting mode into after 90 degree.
Further, hinged safety device described in the utility model is flush-mounted in door leaf side by a door leaf fixture that is provided with U-shaped groove; Described spring buffer mechanism is provided with the spring rotating pin of vertical layout, and the two ends up and down of this spring rotating pin are installed on respectively on two sidewalls up and down of described U-shaped groove.
Further, spring buffer described in the utility model mechanism comprises the sleeve that is connected with door leaf hinge, is located at the torque spring in sleeve, and the two ends up and down of described torque spring are provided with fixed cover and lower fixed cover.
Further, door leaf hinge described in the utility model is fixedly connected with described sleeve.
Further, the utility model also comprises screens round pin, and described lower fixed cover is provided with the locating hole suitable with this screens round pin.
Further, screens round pin described in the utility model is opened into 180 while spending and the locating hole of described lower fixed cover fastens at door leaf.
Further, the two ends up and down of door leaf fixture described in the utility model are provided with the fixing edge of outwards routing up from U-shaped groove, and this is fixing along fixing by screw and door leaf.
Further, on door leaf hinge described in the utility model and door frame hinge, be respectively bending and mutually superpose fixing, described door frame hinge is provided with the strip adjustable screw hole that is triangularly arranged and is parallel to each other, and door frame hinge fixes by three fixed screws and adjustable screw hole and door leaf hinge
The beneficial effects of the utility model are:
The utility model is simple in structure, novel; with hinged safety device; this device plays the effect of buffer limit; adopt spring buffer mechanism, the free opening angle of door leaf is within 90 degree scopes, if want to continue to increase opening angle; owing to being subject to the torsion of spring; must apply certain dynamics could realize, and opening angle is converted to buffer starting pattern after being greater than 90 degree, thereby effectively protects door leaf.The unlatching maximum angle of door leaf is set as 180 degree and can be fixed spacing.The defect that the utility model has overcome existing door leaf opens improper generation shock and the sound.
In addition, door frame hinge is provided with the adjustable screw hole being triangularly arranged, and be connected by adjustable screw between door leaf hinge, the permanent position of adjustment door leaf that not only can be flexible and meticulous, and adjust flexibly the installation site of hinged safety device, make the annexation between door leaf and doorframe reach the most stable triangle locate mode simultaneously, greatly extended the application life of door hinge, effectively prevent because the easy distortion of door hinge unbalance stress finally causes the not smooth situation of door leaf switch.
The utility model good concealment, by the assembling of steel door, opens the door over interior and all can use.The utlity model has noise little, safe and reliable, wear-resistant, corrosion-resistant, simple in structure, with low cost, can popularization and application etc. feature, and be particularly suitable for African country house family and install and use.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Specific embodiment of the utility model is as shown in Fig. 1-5, a kind of hinged safety device of security door that can secondary changes door leaf opening angle, comprise a U-shaped hinge component, this hinge component comprises door leaf hinge 1 and door frame hinge 2, and door leaf hinge 1 is provided with hinged safety device with door leaf connecting place; Hinged safety device is flush-mounted in door leaf side by a door leaf fixture 3 that is provided with U-shaped groove, comprises that can make door leaf open is greater than the spring buffer mechanism of changing buffer starting mode into after 90 degree.The side of door frame hinge 2 is provided with pin hole 22, is connected with doorframe by pin hole 22 and the door hinge latch 23 that is arranged on pin hole 22.
Spring buffer mechanism comprises sleeve 5, torque spring 6, upper fixed cover 7, lower fixed cover 8 and the vertical spring rotating pin 4 of arranging.Sleeve 5 is fixedly connected with door leaf hinge, the interior spring rotating pin 4 that is vertically provided with of sleeve 5; Torque spring 6 is arranged in sleeve 5, is sleeved on spring rotating pin 4, and the two ends up and down of torque spring 6 are connected with lower fixed cover 8 with upper fixed cover 7 respectively; Upper fixed cover 7 and lower fixed cover 8 are located at the two ends up and down of spring rotating pin 4; The two ends up and down of spring rotating pin 4 are fixedly installed in respectively on two sidewalls up and down of U-shaped groove of door leaf fixture 3.
The utility model also comprises screens round pin 9, and screens round pin 9 is positioned at the below of sleeve 5, and lower fixed cover 8 is provided with the locating hole suitable with this screens round pin 9.Screens round pin 9 is opened into 180 at door leaf and can fastens with the locating hole of described lower fixed cover 8 while spending.The two ends up and down of door leaf fixture 3 are also provided with the fixing edge of outwards routing up from U-shaped groove, and this is fixing along fixing by screw 10 and door leaf.
Door leaf hinge 1 and door frame hinge 2 are bending, door frame hinge 2 is provided with the strip adjustable screw hole 21 that is triangularly arranged and is parallel to each other, door frame hinge 2 by three fixed screws 11 and adjustable screw hole 21 and door leaf hinge 1 mutually stack fix, can fine adjustments door leaf hinge 1 and the position relationship of door frame hinge.
The course of work is as follows:
The utility model is to change door leaf opening angle by secondary, and opening angle scope is 90 degree first, and secondary opening angular range is 180 degree.
Opening the door in process of opening first, door leaf is freely opened and is rotated around door hinge latch 23 together with hinge component, and when door leaf is opened into 90 while spending, door frame hinge 2 is limited, cannot be rotated further.If door leaf opening angle is greater than 90 while spending, hinged safety device is started working, door leaf can be in spring buffer mechanism the axle center of spring rotating pin 4 rotate, between upper fixed cover 7 and lower fixed cover 8, produce relative motion, there is elastic deformation in torque spring 6, hinge safety device has started cushioning effect.When door leaf opening angle is less than 180 while spending, cancel after external force, under the effect of torque spring 6, door leaf can automatic slowly returns to the position of 90 degree.Open and reach 180 while spending when door leaf, screens round pin 9 slowly snaps in the locating hole on lower fixed cover 8, screens round pin 9 and the invariant position that coordinating of locating hole can fix door leaf and remain on 180 degree.
The door leaf that the above embodiments are only selected for the utility model is the preferred embodiment of opening angle 90 degree and secondary opening angle 180 first, and the utility model can be changed according to actual conditions twice opening angle of door leaf, to meet the user demand under different occasions.
In the utility model, can not limit interest field of the present utility model with this, therefore, the equivalent variations of doing according to the utility model claim, still belongs to the scope that the utility model is contained.
