The utility model relates to an adaptive angle magnetic frame, which comprises a mirror frame and a mirror foot articulated on both sides of the mirror frame. The mirror foot is provided with an articulated axis articulated in the mirror frame. The angle adjusting device of the hinge joints of the mirror feet and the frame is arranged, and the angle adjustment device includes an adjusting shaft, an elastic part, a regulating groove and an adjusting block. The slot is set at the end of each mirror foot toward the frame. The adjusting shaft is fixed to the outer circumferential surface of the articulated axis and into the adjustment slot. The adjustment block is slipping to the adjusting shaft. The elastic part is installed in the adjusting slot and the adjustment block is reset to the mirror frame. The mirror frame is facing the end of the mirror, and the cam surface is filled between the mirror foot and the cam surface and is filled with the cam surface. The fixed slot is provided with a buffer body, and the adjusting groove is provided with a pretightening force adjusting mechanism for adjusting the pretightening force of the elastic component. By adopting the above scheme, the utility model provides a magnetic frame with adaptive angle of expansion according to the maximum unfolding angle between the mirror foot and the mirror frame, which is automatically adjusted by the different wearer.

自适应展角的磁性镜架
本技术涉及一种镜架,具体涉及一种自适应展角的磁性镜架。
技术介绍
眼镜,以矫正视力或保护眼睛而制作的简单光学器件,由镜片、镜架组成。分近视眼镜、远视眼镜、老花眼镜及散光眼镜四种,其既是保护眼睛的工具,又是一种美容装饰品。镜架包括镜框及镜框两侧的镜脚,镜脚铰接于镜框且具有最大展开角度,为了使眼镜稳定佩戴,调整后的镜架往往只适用于眼镜拥有者,借予他人佩戴时往往会产生不适,或无法稳定放置,如果镜脚相对镜框的端部设计为自由转动的方式,意外的力量从后方或斜后方推动镜脚时,镜框易从鼻梁上脱离,导致眼镜落地,严重时会造成损坏。
技术实现思路
针对现有技术存在的不足,本技术的目的在于提供一种根据不同佩戴人群自动调节镜脚与镜框之间的最大展开角度的自适应展角的磁性镜架。为实现上述目的,本技术提供了如下技术方案:包括镜框及分别位于镜框两侧的镜脚,所述的镜脚设置有铰接于镜框的铰接轴,其特征在于:各所述的镜脚与镜框的铰接处设置有展角调节装置,所述的展角调节装置包括调节轴、弹性件、调节槽及调节块,所述的调节槽设置于各镜脚朝向镜框的端部,所述的调节轴固定于铰接轴外周面并伸入调节槽,所述的调节块滑移于调节轴,所述的弹性件安装于调节槽并将调节块向镜框复位,所述的镜框朝向镜脚的端部设置有调节块相抵的凸轮曲面,该凸轮曲面与铰接轴的中心轴线的距离随着镜脚展开方向逐渐增加,所述的镜脚与凸轮曲面之间填充且固定设置有缓冲体,所述的调节槽还设置有调节弹性件预紧力的预紧力调节机构。通过采用上述技术方案,在镜脚向外侧展开时,凸轮曲面会逐渐将调节块向弹性件压缩,被压缩后的弹性件向调节块提供反 ...
