Kind Code:
A1
Abstract:
Disclosed is a hinge assembly comprising a guide body (10), a first connecting member (40), a second connecting member (50), a first elastic member (20) and a second elastic member (30), wherein a first guide groove (13) and a second guide groove (14) are correspondingly provided in a first end face (11) and a second end face (12) of the guide body (10), the first guide groove (13) intersects with the second guide groove (14), and a first connecting end (41) of the first connecting member (40) and a second connecting end (51) of the second connecting member (50) are hinged in the guide body (10) and are rotating centers of each other, such that a glasses temple (70) can rotate in multiple directions relative to an end piece (60). A first flange (63) is arranged on an end piece end face (621), such that the first flange (63) abuts against the first end face (11) when the first connecting end (41) pivots outwards, the glasses temple (70) is prevented from rotating by a larger angle, and the situation wherein when the outward pivoting angle of the first connecting member (40) is larger than or equal to 90°, the first connecting member (40) and the end piece (60) cannot rebound because of clamping stagnation is prevented. The guide body (10) is provided with a high convex surface and a low surface at least on a front end face (111) of the first end face (11), the high convex surface is used for coming into contact with the end piece end face (621) to be worn away, and the low surface is prevented from being worn away and can display a colouring layer thereon, thereby improving the product quality.
