Description

Technical Field

[0001] The utility model relates to the technical field of hardware parts, in particular to a novel stainless steel buffer hinge. Background Art

[0002] A hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other. The hinge can be composed of movable components or foldable materials. For example, a Chinese patent discloses a stainless steel seven-shaped hinge (publication number CN209586935U), which includes a first hinge monolithic piece, a second hinge monolithic piece, a connecting piece, a torsion spring and a buffer assembly. One end of the connecting piece is welded and fixed to the second hinge monolithic piece, and the other end passes through the first hinge monolithic piece to extend outward. The connecting piece and the first hinge monolithic piece are slidably connected. The buffer assembly includes a connecting rod and a buffer block. The buffer block is arranged between the connecting pieces. The connecting rod passes through the connecting piece and the buffer block in turn, and both ends are fixedly connected to the first hinge monolithic piece. The buffer block and the connecting piece are slidably connected. The two ends of the torsion spring are respectively connected to the first hinge monolithic piece and the second hinge monolithic piece. The utility model has a novel structure and is safe to use, which prevents the seven-shaped hinge from causing harm to the lower body and human body during the opening and closing process.

[0003] However, after long-term use, the above patent will cause greater wear between the connecting piece and the first hinge piece and the second hinge piece, and make it impossible to generate friction between the buffer block and the connecting piece during sliding, thereby failing to achieve the buffering effect, and it is inconvenient to replace the hinge piece, resulting in the entire hinge being unusable. For this reason, we propose a new stainless steel buffer hinge to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:
