Novel movable connecting mechanism and eyeglasses

Abstract

The invention discloses a novel movable connecting mechanism and a pair of eyeglasses. The movable connecting mechanism comprises a fixed part and a movable part, wherein the two diagonal lines of a square fixing hole are parallel to two sides which rotationally form an included angle with the movable part respectively; one end of the movable part is provided with two elastic bars; each elastic bar is provided with a limiting shaft; at least one end of each limiting shaft is positioned in a square fixing hole; balance points of the two limiting shafts are positioned in two opposite hole wallsof the square fixing hole; the spacing between the two limiting shafts is largest when a movable component is in open and closed states; the spacing between the two limiting shafts is smallest when the movable component is at a balanced position between the open and closed states. The elastic bars change from a compressed state to a released state in a process of opening from a folded state or folding from an open state, and stress balance points exist between the limiting shafts and the square fixing holes; after the limiting shafts cross a balance position, the limiting shafts are opened automatically or move towards a folding direction under the action between the elastic bars and the square fixing holes; the novel movable connecting mechanism has a simple and reliable structure, and iswidely applied to hinging of two objects or articles.

Description

technical field [0001] The invention relates to the technical field of connection mechanisms, in particular to a novel movable connection mechanism and glasses. Background technique [0002] Glasses are getting lighter and lighter, and the frames and temples are usually connected by hinges. The general hinge connection has a relatively simple structure, but when the glasses are opened or put away, the mirror feet cannot automatically rotate to the fully stowed or fully opened state after turning a certain angle to the stowed or opened direction. At present, there is also a kind of elastic part arranged at the hinge between the mirror frame and the mirror foot. When the mirror foot is turned over the balance angle in the direction of closing or opening, the elastic part is in a stretched state, and after turning over the balance angle, the elastic part acts Rotate downward toward the direction of the rotation trend to realize the automatic opening or retracting of the temple...

The general hinge connection has a relatively simple structure, but when the glasses are opened or put away, the temples cannot automatically turn to the fully stowed or fully opened state after turning a certain angle in the direction of stowing or opening

At present, there is also a kind of elastic part arranged at the hinge between the mirror frame and the mirror foot. When the mirror foot is turned over the balance angle in the direction of closing or opening, the elastic part is in a stretched state. After turning over the balance angle, the elastic part acts Rotate downwards in the direction of the rotation trend to realize the automatic opening or closing of the temples, but the structure is complex and there are many parts, which increases the difficulty of assembly
