Abstract

The invention provides a heavy-load conical hinge. The heavy-load conical hinge comprises two hinged blades, a conical hinge pin, nylon pin sleeves and pin caps. Connecting pieces of the two blades are oppositely and coaxially arranged and internally provided with the nylon pin sleeves respectively, and skirt parts of the nylon pin sleeves are oppositely arranged; a conical part of the conical hinge pin is inserted into pin holes of the two oppositely-arranged nylon pin sleeves, and the inner walls of the pin holes are tightly attached to the surface of the conical hinge pin; the upper end face and the lower end face of an annular part of the conical hinge pin abut against the skirt parts of the two nylon pin sleeves respectively; the pin caps are packaged at the two ends of the conical hinge pin. By means of the heavy-load conical hinge, heavy-load hinged connection can be achieved, and no noise exists during movement.

Description

technical field [0001] The invention relates to the field of mechanical movable components, in particular to a heavy-duty conical hinge. Background technique [0002] Hinges are commonly used moving parts in the mechanical field, and are commonly used in mechanical joints and furniture doors and windows. [0003] Hinges are mostly made into complete finished components for sale. Common products include butterfly hinges, door hinges, etc. In view of the functional characteristics of the hinge product, the hinge pin needs to bear a large shear force during use, and may also need to bear a large bending moment. Just like the door hinges commonly used in the home environment, because it is connected with the door panel, it needs to bear the weight of the entire door panel. In addition to the hinge pin bearing shear force and bending moment, the connecting part of the two discs is also easy to rub against each other due to load. . In addition, metal parts are also more prone t...
