Abstract

The invention discloses an automobile door hinge provided with mounting screw holes, which comprises a first hinge and a second hinge. It includes a first pin shaft, a first slanting rod, a second pin shaft, a second slanting rod and a third pin shaft, the inner sides of the first slanting rod and the second slanting rod are rotatably connected by the second pin shaft, and the The inside of the right end of the first oblique rod is rotatably connected with the second hinge through the first pin shaft. The car door hinge with mounting screw holes has a scientific and reasonable structure, and is safe and convenient to use. Through the cooperation between the slider, the first oblique rod, the second oblique rod, the nut, the first hinge and the second hinge, during use In the present invention, the user can adjust the position of the slider, and then tighten the nut after determining the position of the slider, thereby avoiding the problem that the automobile door hinge in the prior art cannot adjust the limit opening angle according to the needs of the user.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile door hinge provided with mounting screw holes. Background technique [0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow relative rotation between the two. The hinge can be composed of movable components or foldable materials. The door and body of a car are formed by hinges. The connection is fixed, and the hinge is fastened with bolts through the positioned mounting screw hole. Although the existing technology can realize the fixed connection between the hinge and the car door through the elliptical screw hole, there are problems in the use of the car door hinge. According to the user's need to adjust the limit opening angle, the car door hinge is only supported by the pin shaft and has no auxiliary support during the opening and closing process, resulting in a large wear of the pin shaft, and the limit structure ...
