Heavy hinge

Abstract

The invention discloses a heavy hinge, and belongs to the technical field of hardware. The heavy hinge is used for connecting two components needing to be opened and closed. The heavy hinge comprisesa bottom plate, a supporting arm, a short connecting plate and a long connecting plate, the bottom plate is used for being connecting with one of the two components, the supporting arm is connecting with the other component, the short connecting plate and the long connecting plate are used for connecting the supporting arm and the bottom plate, the first end of the short connecting plate is hingedto the supporting arm to form a first supporting arm hinge point, the second end of the short connecting plate is hinged to the bottom plate to form a first bottom plate hinge point, the first end ofthe long connecting plate is hinged to the supporting arm to form a second supporting arm hinge point, the second end of the long connecting plate is hinged to the bottom plate to form a second bottom plate hinge point, a first spacing is arranged between the first supporting arm hinge point and the second supporting arm hinge point, and a second spacing is arranged between the first bottom platehinge point and the second bottom plate hinge point. According to the heavy hinge, opening and closing of the hinge are achieved through a rotating structure; and compared with a sliding support in the prior art, the smoothness, the portability and the workability of a switch are enhanced, and the bearing capacity is improved.

Description

technical field [0001] The invention relates to the technical field of hardware, and more specifically, to a heavy-duty hinge. Background technique [0002] Hinges usually refer to hinges, and hinges used in doors and windows that can be opened are usually called sliding stays, that is, sliding stay hinges. Such as figure 1 As shown, the sliding stay hinges in the prior art are all composed of a bracket arm 10 , a cantilever 20 , a slide rail 30 and a slider 40 . Wherein, the slide block 40 is installed on the slide rail 30, and there are multiple cantilevers 20, which can be divided into long cantilever, short cantilever and oblique cantilever according to length and connection position. The long cantilever is hinged between the slide rail 30 and the support arm 10 , the short cantilever is hinged between the slider 40 and the support arm 10 , and the oblique cantilever is hinged between the slider 40 and the long cantilever. Both the bracket arm 10 and the cantilever ar...

Problems solved by technology

Due to the inclusion of a plurality of interacting connecting rods, there are many hinge points, the force acting on the slider 40 is a comprehensive force in all directions, and the rotation of the connecting rod acts on the slider 40 to achieve linear sliding, involving rotation and In this structure, on the one hand, when the force is transmitted, it is easy to be affected by the force offset caused by the structure and the force transmission is not smooth, resulting in unsmooth sliding, and the hinge point, slider 40 and If the gap fit between the slide rails 30 has a large error, it is easy to cause sliding blockage or jamming; on the other hand, the thickness of each connecting rod is limited, so that the connecting rods are thinner and the load-bearing capacity is smaller, which may easily cause the sliding stay to spread out. After that, it closes automatically, resulting in a short service life of the sliding stay and cannot be used in heavy structures
