Including door frame hinge piece, door leaf leaf of hinge, door frame hinge piece and door leaf leaf of hinge are connected as a single entity by hinge shaft, and there is anti-forcible entry
The problem of energy force difference, criminal is just easily pounded using common machine tools and caps off head, knocks out hinge shaft to destroy hinge, so as to broken
Door and enter to steal property, cause personal safety and family's property that cannot ensure, therefore it is good to develop a kind of anti-violence forcible entry performance
Backflap hinge the problem of being extremely urgent.For this purpose, many manufacturers and knowledgeable people are developed and developed, but so far still
There is not comparatively ideal product to emerge.
The content of the invention
To overcome the above-mentioned deficiency present in existing backflap hinge, the purpose of this utility model is to provide a kind of structure design and closes
It manages, assemble bright conjunction that is simple and convenient, rotating antitheft door anti-violence forcible entry flexible, that high mechanical strength, anti-violence forcible entry ability are good
Page.
The utility model solves technical solution used by its technical problem, it include door frame hinge piece, door leaf leaf of hinge,
Hinge shaft component, door frame hinge on piece are correspondingly provided with door frame hinge upper and lower volume set, and door leaf leaf of hinge is equipped with door leaf hinge volume set, institute
The hinge shaft component stated is made of upper and lower pick-proof axis, and fixed pin holes are correspondingly provided on upper and lower pick-proof axis, and door frame hinge upper and lower volume is put on
It is correspondingly provided with volume set pin hole and positioned at the inside of hinge, upper and lower pick-proof axis correspondence is rotationally inserted through door frame hinge upper and lower volume set
Enter in door leaf hinge volume set, fixed pin will be on upper and lower pick-proof axis and door frame hinge by rolling up that set pin hole is corresponding with fixed pin holes cooperation
Last volume set fixation is connected as a single entity, and door leaf leaf of hinge blocks fixed pin when door leaf leaf of hinge is combined with door frame hinge piece.
The further scheme of the utility model, the axis of pick-proof up and down is by cap head, door frame hinge axis and door leaf hinge axis
Three sections form a whole, and cap head diameter is more than the diameter of door frame hinge axis, and the diameter of door frame hinge axis is more than door leaf hinge axis
Diameter, cap head correspondence is blocked in door frame hinge upper and lower volume and puts on, and door frame hinge axis covers secure fit with door frame hinge upper and lower volume,
Door leaf hinge axis is rotatably assorted with door leaf hinge volume set.
The further scheme of the utility model is correspondingly provided between the door frame hinge upper and lower volume set and door leaf hinge volume set
The gasket or bearing being sleeved on door frame hinge axis.
Seam welding is rolled up on the further scheme of the utility model, the door frame hinge upper and lower volume set and door leaf hinge volume set
It is fixed.
The further scheme of the utility model, the door frame hinge on piece be equipped with the fixed doorframe mounting hole of doorframe,
Door leaf leaf of hinge is equipped with and the fixed door leaf mounting hole of door leaf.
With the above structure, have the following advantages compared with the prior art and effect：When due to pick-proof axis cap head with
Hinge shaft one-pass molding, so cap head is not easy to be knocked out；Second is that since upper and lower pick-proof axis passes through fixed pin and the conjunction of corresponding doorframe
Page upper and lower volume set fixation is connected as a single entity, and fixed pin is mounted on the inside of hinge, even if cap head is knocked out, hinge shaft is acted in fixed pin
Under can not also be knocked out, greatly improve backflap hinge violence forcible entry difficulty；Third, due on door frame hinge axis and door frame hinge
Last volume covers secure fit, and door leaf hinge axis is rotatably assorted with door leaf hinge volume set, and door frame hinge upper and lower volume set is rolled up with door leaf hinge
The gasket or bearing being sleeved on door frame hinge axis are correspondingly provided between set, door leaf leaf of hinge rotates flexibly light；Fourth, through authority
Testing agency is detected, and can not be dismantled, complied with the national standard requirements before the deadline using common machine tools.
