a hinge mechanism

Abstract

The invention provides a hinge mechanism. The hinge mechanism comprises a first blade, a limiting element and a linkage element. The linkage element comprises a first pivot shaft and a second pivot shaft. The linkage element is coupled with the first blade through the first pivot shaft in a pivoted mode. The second pivot shaft is arranged on the linkage element and can rotate around the axis of the second pivot shaft. The second pivot shaft comprises a limiting area, and the limiting area of the second pivot shaft comprises a wide part and a narrow part. The first blade comprises a limiting clamping groove. The limiting clamping groove comprises a shaft hole and a pivot shaft channel extending from the shaft hole to the outside of the limiting clamping groove. The diameter of the shaft hole is larger than the width of the wide part of the limiting area of the second pivot shaft. The width of the pivot shaft channel is larger than the width of the narrow part of the second pivot shaft and is smaller than the width of the wide part of the second pivot shaft. By controlling the position of one pivot shaft rotating around the axis of the pivot shaft, the hinge mechanism can open or close the linkage element, other parts connected with the linkage element can rotate around the first pivot shaft, no outside tools are needed, and the mechanism is simple, efficient and reliable.

Description

technical field [0001] The invention relates to the field of mechanical design, in particular to a hinge mechanism. Background technique [0002] Existing hinge structures usually can only hinge two blades together, but cannot provide multiple hinge degrees of freedom, especially there is no hinge structure that can controllably activate the next hinge freedom by controlling the rotation angle of one of the blades Spend. In the prior art, it is often necessary to use external tools or operate structures other than the blades to activate the next hinge degree of freedom, which is complicated in structure and inconvenient in operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a hinge mechanism. [0004] The present invention is achieved in the following way: a hinge mechanism includes a first blade, a limiter and a linkage, the linkage includes a first pivot shaft and a second pivot shaft, and the linkage ...
