FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the anti-pry door with hidden coaxial hinge comprises a door leaf 1 and a door frame 2, wherein the door leaf 1 is connected with the door frame 2 through a hinge 3.
The fixed reinforcing steel plate 4 that is provided with of side of 1 installation hinge one side of door leaf, reinforcing steel plate 4 is extended to the bottom by 1 top of door leaf, and the side of protection door leaf is difficult by the sled on the one hand, and on the other hand can make the hinged joint more firm.
The section of the door frame 2 comprises three steps, and the hinge 3 is arranged corresponding to the position of the first step 2-1; in a door closing state, the side edge of the door leaf 1 integrally corresponds to the position of a second-stage step 2-2 in the middle and locally corresponds to the position of a first-stage step 2-1; the third step 2-3 is used to protect one side corner of the door leaf 1.
A hinge mounting through hole is formed in an overturning surface 2-4 of the door frame 2, which is used for connecting the first-stage step 2-1 and the second-stage step 2-2, and a hinge fixing piece 5 is welded in the door frame 2 corresponding to the hinge mounting through hole.
The hinge 3 comprises a first installation part 3-1 and a second installation part 3-2 which can be turned over relatively, wherein the first installation part 3-1 is used for being fixedly installed with the door leaf 1, and the second installation part 3-2 is used for being fixedly installed with the door frame 2. The first installation part 3-1 is fixedly connected with the door leaf 1 through a reinforced steel plate 4, and the second installation part 3-2 is fixedly connected with the hinge fixing part 5 after penetrating through the hinge installation through hole.
The side of the door leaf 1 is fixedly provided with a hinge protection section bar 4, and the hinge protection section bar 4 is made of metal section bars. The hinge protection profile 4 has a protection cylinder part 4-1 and a mounting surface part 4-2, the side wall of the protection cylinder part 4-1 being semi-open. The closed surface of the protective cylinder part 4-1 faces the outside of the anti-prying door body, and the open surface faces the turnover surface 2-4 in the door closing state. The rotating shaft part of the hinge is positioned in the protective cylinder part 4-1. Can reach like this and hide the hinge effect, can effectively protect the hinge and can not expose outside when the pick-proof door is closed, relatively more pleasing to the eye on the one hand, on the other hand avoids being disassembled by the violence, can reduce the hinge simultaneously and by oxidation increase of service life. The metal section has higher hardness, and achieves the anti-prying and anti-sawing effects. The inner shape of the protective cylinder part 4-1 of the hinge protective section bar is approximately the same as the hinge axis, and the first mounting part 3-1 and the second mounting part 3-2 can rotate freely relatively. The first installation part 3-1 of the hinge is fixedly connected with the hinge protection section bar 4 at first, so that the plurality of hinges are positioned on a vertical straight line of the hinge protection section bar, the position of the hinge is fixed by utilizing the rigidity of the hinge protection section bar and cannot be changed, and the axes of the plurality of hinges can be ensured to be completely on the same straight line after long-term use, so that the upper, middle and lower hinges cannot move under different axes, and the use of the anti-prying door is influenced.
The mounting surface part 4-2 of the hinge protection profile 4 is fixed on the side edge of the door leaf 1, and in order to enhance the protection effect, the mounting surface part 4-2 integrally covers one side edge of the door leaf 1. The first mounting portion 3-1 of the hinge, the mounting surface portion 4-2 of the hinge protection profile and the reinforcing steel plate 4 may be fixedly mounted together by means of screws 7 passing through them in this order.
