Hole is connect to block to avoid spring disengaging, the top of card is located in annular groove and card still has the trend expanded outwardly, this
Scale spring will not fall off in use, and stabilized structure is reliable；When needing replacing spring, card is inwardly collapsed by tool
Clamp spring is taken out, it is more convenient to replace spring.
In a kind of elastic hinge of above-mentioned glasses, the top of the card has the flange turned down outward.Card
Top when being located in annular groove, flange is stuck in annular groove so as to be more securely clamped in annular at the top of card recessed
Slot.
In a kind of elastic hinge of above-mentioned glasses, the mandrel of direct rod shape, the core are equipped in the spring
Axis, which has, contradicts for outer spring end and is inserted into the connecting pin in card, and the contact surface of the connecting pin and card is umbrella cover shape.
Mandrel make spring during the work time will not Bending Deformation, ensure that the job stability of spring, and connecting pin avoids card
It collapses during the work time, and the elastic force that spring provides makes connecting pin apply the power expanded outwardly to card, clamp spring will not fall
It falls, ensure that the job stability of clamp spring.
As another situation, in a kind of elastic hinge of above-mentioned glasses, the closeouts are and connecting hole spiral shell
The screw of line connection.The dismounting of screw and spring is more convenient quick in this way.
Compared with prior art, the elastic hinge of this glasses is compact-sized firm, and good operating stability, spring is replaced convenient
Fast so that the elastic hinge of this glasses is suitble to the requirement of different elastic force, different open angles, elastic property more to stablize.
