In the hinge structure, the inclination angle of the pressure receiving surface is 25 to 45 degrees.

In the hinge structure, the hinge part is provided with a through hole in an axial direction of the screw, the female hinge is provided with a threaded hole and a counter bore which are both arranged in an axial direction of the screw in a penetrating manner, the threaded hole and the counter bore are distributed on two sides of the movable groove, and the rod part of the screw sequentially penetrates through the counter bore and the through hole and is in threaded connection with the threaded hole. By adopting the design, the device has the advantages of simple structure and convenience in installation.

In the hinge structure, the head of the screw is located in the counter bore, the inner side wall of the counter bore is provided with a counter bore bottom surface, the counter bore bottom surface is located between the head and the hinge part, and the head is pressed against the counter bore bottom surface. The head portion is used for limiting the rotating position of the screw, so that the screw can be installed in place in one time.

Compared with the prior art, this hinge structure adopts the mode that the face that receives pressure and inclined plane and paste to contact through setting up articulated portion and activity groove diapire to change current point contact into the face contact of this application, improve the area of contact of articulated portion and activity groove diapire, thereby effectively avoid both to take place deformation when receiving the extrusion, make public hinge rotate to restricted position accurately, improve turned angle's accuracy nature.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 3, the hinge structure includes a male hinge 1 and a female hinge 2, wherein the male hinge 1 includes a block-shaped hinge portion 1a, the female hinge 2 has a movable groove 2a for inserting the hinge portion 1a, and the hinge portion 1a is rotatably disposed in the movable groove 2a by a screw 3.

Specifically, as shown in fig. 1, 2, 3, and 4, the hinge portion 1a has a through hole 1b penetrating in the axial direction of the screw 3, the female hinge 2 has a threaded hole 2b and a counter bore 2c both penetrating in the axial direction of the screw 3, and the threaded hole 2b and the counter bore 2c are distributed on both sides of the movable groove 2 a. The rod end of the screw 3 sequentially penetrates through the counter bore 2c and the through hole 1b and is in threaded connection with the threaded hole 2b, the head 3a of the screw 3 is located in the counter bore 2c, the inner side wall of the counter bore 2c is provided with a counter bore bottom surface 2d, the counter bore bottom surface 2d is located between the head 3a and the hinge portion 1a, and the head 3a is pressed against the counter bore bottom surface 2 d. The head 3a serves to define the rotational position of the screw 3, allowing the screw 3 to be mounted in place at one time.

As shown in fig. 2 and 3, the bottom wall of the movable groove 2a is composed of a pressure receiving surface 2a1 and an abdicating surface 2a2 which are distributed from top to bottom, and the abdicating surface 2a2 and the pressure receiving surface 2a1 are connected together.
