The invention relates to a self-locking type safe anti-theft hinge. The self-locking type safe anti-theft hinge comprises a door frame connecting hinge plate, a door leaf connecting hinge plate, bearings, a spindle and plugs, wherein door frame connecting hinge plate coiling drums and door leaf connecting hinge plate coiling drums are arranged on the inner side of the door frame connecting hinge plate and the inner side of the door leaf connecting hinge plate correspondingly and are connected alternately; the bearings are installed between the coiling drums; the spindle is inserted into the door frame connecting hinge plate coiling drums, the door leaf connecting hinge plate coiling drums and the bearings; and the plugs are inserted at the two ends of the door frame connecting hinge plate coiling drums and the door leaf connecting hinge plate coiling drums. The self-locking type safe anti-theft hinge is characterized in that the door frame connecting hinge plate is further provided with an anti-falling locking hole; and the door leaf connecting hinge plate is further provided with an anti-falling locking hook which can be embedded in the anti-falling locking hole. The self-locking type safe anti-theft hinge is scientific and reasonable in structural design, has the advantages of being easy to machine, tight in self-locking, good in self-locking effect and the like, and is highly creative.
Description
technical field [0001] The invention belongs to the field of hardware products, in particular to a self-locking safety anti-theft hinge. Background technique [0002] Hinge is an indispensable hardware product for installing doors and windows. Most of the existing door hinges are composed of a door frame connection hinge plate, a door leaf connection hinge plate, a central axis and two ends of the plugging. The shaft is installed on the reel, and the central shaft is inserted into the above-mentioned reel to connect the two, and it is fixed by the plugging at both ends. During the installation and use of the hinge, most of its reel and central shaft are exposed, and the central shaft may be pulled out by burglars. After the central shaft is pulled out, the door leaf may be opened without unlocking. CN2125656 and CN101592000 respectively disclose a kind of anti-theft hinge, but the welding of the safety buckle is troublesome, and there are problems such as great difficulty ...
