有益效果beneficial effects
与现有技术相比，本发明的有益效果是：Compared with the prior art, the beneficial effects of the present invention are:
1. 快速省时。翻转眼镜向上翻转是由扭转弹簧带动的，只需用手分开翻转镜框和固定镜框一段缝隙后，翻转镜框就会快速翻转到固定镜框的前上方，节省了向上翻转的时间，减少了切换时间。1. Quick and time-saving. The upward flipping of the flipping glasses is driven by a torsion spring. You only need to separate the flipping frame and the fixed frame by hand. After a gap, the flipping frame will quickly flip to the front and top of the fixed frame, saving the time of flipping upward and reducing the switching time.
2. 方便省力。目前的翻转眼镜转轴必须足够紧，否则使用时间久了磨损后会松动失灵，这使得整个翻转过程较费力。本发明安装了扭转弹簧和永磁体，两个镜框靠磁铁吸合，用手分开两个镜框后可利用弹簧扭转力实现镜片的自发向上翻转，中间过程不需要再用力，需要上翻时只需让翻转镜框与固定镜框分开一小段缝隙，靠扭转弹簧的扭转力就可以让翻转镜框向上翻转;向下翻转时，使用很小的力量翻转到即将靠近时靠磁铁的吸力吸合在一起，使用轻松自如。2. Convenient and labor-saving. The current rotating shaft of flipping glasses must be tight enough, otherwise it will loosen and malfunction after being worn for a long time, which makes the entire flipping process more laborious. The invention is equipped with a torsion spring and a permanent magnet. The two frames are attracted by the magnets. After the two frames are separated by hand, the torsion force of the spring can be used to realize the spontaneous upward flipping of the lens. No additional force is required in the middle process. When the two frames need to be flipped up, only Separate a small gap between the flipping frame and the fixed frame, and rely on the torsion force of the torsion spring to flip the flipping frame upwards; when flipping downwards, use a small force to flip them together until they are about to be close together by the suction of the magnet. Effortless.
3. 体积小。扭转弹簧的两端采用向内过心弯折的横杆结构，比两端向外伸出的扭转弹簧的结构尺寸小很多，全部结构都在轴套内部，整体结构尺寸更小。3. Small size. The two ends of the torsion spring adopt a cross-bar structure that is bent inward, which is much smaller than the torsion spring with both ends extending outward. The entire structure is inside the shaft sleeve, and the overall structural size is smaller.
4. 制作容易，调整方便。翻转铰链的开口销轴和开口螺钉容易制作，扭转弹簧安装和调整扭矩方便，开口螺钉的多头螺纹结构可以方便调整扭转弹簧的扭矩力度，可以是半圈扭矩，也可以是1/3或1/4圈的扭矩，当扭矩不合适时开口螺钉可以方便旋转出来后重新调整好扭转弹簧的预紧圈数再重新安装好，调整非常方便。开口螺钉的多头螺纹结构可以利用扭转弹簧的反向扭矩将开口螺钉与套筒拧紧得更加牢固，不会脱出。4. Easy to make and adjust. The cotter pin and cotter screw of the flip hinge are easy to make, and the torsion spring is easy to install and adjust the torque. The multi-thread structure of the cotter screw can easily adjust the torque strength of the torsion spring, which can be half a turn of torque, or 1/3 or 1/ 4 turns of torque. When the torque is not appropriate, the open screw can be easily rotated out and the number of preload turns of the torsion spring can be adjusted before reinstalling. The adjustment is very convenient. The multi-thread structure of the open-ended screw can use the reverse torque of the torsion spring to tighten the open-ended screw and the sleeve more firmly and prevent it from coming out.
5、避免遗忘。本发明的快速翻转眼镜的翻转镜架与固定镜架是一体结构，翻转镜架始终带在身边，不会忘记丢失翻转镜架。5. Avoid forgetting. The flipping frame and the fixed frame of the quick flipping glasses of the present invention have an integrated structure. The flipping frame is always with you and you will never forget to lose the flipping frame.
