Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides a self-locking anti-theft hinge, as shown in figures 1 to 4, which comprises a first page plate 1, a second page plate 2 and a connecting shaft 3 for connecting the first page plate 1 and the second page plate 2; the first page plate 1 and the second page plate 2 are respectively provided with a first reel 11 and a second reel 21 which are coaxial, and the connecting shaft 3 is inserted into the first reel 11 and the second reel 21 to connect the first page plate 1 and the second page plate 2, so that the relative rotation of the first page plate 1 and the second page plate 2 is realized.
Unlike the existing hinge, the outer wall of the connecting shaft 3 has a protruding portion 31, and one end of the first roller 11 near the second roller 21 is provided with a receiving groove 111 adapted to the protruding portion 31; the second drum 21 is provided with a relief groove 211, and the accommodating groove 111 is co-linear with the relief groove 211 when the first page 1 and the second page 2 are in an open state.
Wherein, in order to make the relief groove 211 and the accommodating groove 111 collinear, the protruding part 31 can enter along the relief groove 211 into the accommodating groove 111; the relief groove 211 has a linear structure with two open ends, and an opening is formed at one end of the accommodating groove 111 near the second drum 21.
Wherein, in order to make the protruding part 31 completely enter the accommodating groove 111, the protruding part 31 is prevented from interfering the relative rotation of the first page plate 1 and the second page plate 2; the length of the receiving groove 111 is at least greater than the length of the protruding portion 31.
When the anti-theft hinge is used, the first winding drum 11 and the second winding drum 21 are aligned, the first page plate 1 and the second page plate 2 are rotated relatively, the abdication groove 211 and the containing groove 111 are positioned on the same horizontal line, and then the connecting shaft 3 is inserted, so that the protruding part 31 on the connecting shaft 3 enters the containing groove 111 along the abdication groove 211 to complete the assembly of the anti-theft hinge. When the first and second sheets 1 and 2 are rotated relatively, the connection shaft 3 is rotated by the receiving groove 111 and the protruding portion 31, thereby changing the relative positions of the protruding portion 31 and the second drum 21. At this time, the position of the protruding portion 31 is shifted, so that the second drum 21 limits the protruding portion 31, so that the connecting shaft 31 cannot be pulled out, thereby avoiding the risk of the connecting shaft 3 being pried out in the door-closed state, and achieving the anti-theft purpose.
Further, the first page plate 1 and the second page plate 2 are provided with through holes 4 for fixing the first page plate 1 and the second page plate 2 on the door and the door frame respectively through screws.
Further, the end of the connecting shaft 3 near the protruding portion 31 has a limiting portion 32 for contacting with the end of the second spool 21 far from the first spool 11.
The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
