Embodiment Construction
[0016] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0017] refer to Figure 1 to Figure 5 , propose an embodiment of the door hinge of the present invention:
[0018] A door hinge includes two hinge leaves 1, a shaft core 2, multiple bearings 3 and two flat heads 4. One hinge 1 has two connecting rings 11 adapted to the shaft core 2, the other hinge 1 has three connecting rings 11 adapted to the shaft core 2, and the positions of the connecting rings 11 on the two hinges 1 are mutually Crossed, the two hinges 1 are rotatably connected to the shaft core 2 through the connecting ring 11 . The bearing 3 is installed on the shaft core 2 , and the bearing 3 is located between two adjacent connecting rings 11 . The flat head 4 is installed on the outer end of the connecting ring 11 located at the two ends of the shaft core 2 .

The invention discloses a door hinge which comprises two hinges, a shaft core, a bearing and a flat head, wherein the hinges are provided with at least one connecting ring matched with the shaft core;the hinges are rotationally connected with the shaft core by virtue of the connecting rings; the positions of the connecting rings on the two hinges are intercrossed; the bearing is arranged on the shaft core and positioned between two adjacent connecting rings; the flat head is arranged at the outer end of the connecting rings positioned at two ends of the shaft core; the flat head comprises a head and a connecting post; the connecting post is vertically positioned at the lower end of the head and matched with the inner cavity of the connecting ring; a circle of protruding convex rings are arranged on the outer wall surface of the connecting post; a circle of clamping grooves which are inwards concavely formed and matched with the convex rings are formed in the inner cavities of the connecting rings positioned at two ends of the shaft core; when the flat head is pressed into the corresponding connecting ring, the convex rings are clamped into the clamping grooves, so that the flat head is fixed at the end of the connecting rings of the hinges, the connecting structure is high in stability, the flat head does not drop, and the safety is ensured.
Description
technical field [0001] The invention relates to the field of door hinges, in particular to a door hinge with a flat head. Background technique [0002] A door hinge, also known as a hinge, is a part that connects two parts of an object and enables it to move. It generally includes two hinges, a shaft core, a bearing, and a flat head. The connecting ring and bearing of the hinge are installed on the shaft core. The hinges are rotatable, and the flat ends are plugged into the ends of the connecting rings located at both ends. The existing flat head is generally directly pressed in, and after long-term use, the flat head is easy to loosen and fall off, which is not safe. Contents of the invention [0003] The main purpose of the present invention is to provide a door hinge with a flat head, aiming at realizing the stable installation of the flat head and preventing it from falling off. [0004] The invention proposes a door hinge, which includes two hinges, a shaft core, a ...
