本申请的工作原理：How this application works:

把铰杯1安装在柜门上，底座7安装在柜子上，柜门打开时，即为铰链开启状态，如图2、4、6所示，此时铰杯1拉拽第一连杆2和第二连杆3，与第一连杆2铰接的扭簧5被扭转产生弹力，第二连杆3的夹持部31向右转动，带动转动器8与缓冲器9回到相贴位置，此时缓冲器9在原始位置无压缩。随着铰链的关闭，如图1、5所示，铰杯1促使第一连杆2和第二连杆3回转，第二连杆3的夹持部31带动转动器8向左转动，但由于扭簧5的中段转臂52抵压在胶套13，扭簧5所产生的回复弹力传递到转动器8，使转动器8只能慢慢向左转顶压缓冲器9，使缓冲器9被压缩，达到关门缓冲的效果。本申请的转动器8和缓冲器9的结构设计更保证了柜门的小角度缓冲，开门5度以上即能进行缓冲。The hinge cup 1 is mounted on the cabinet door, and the base 7 is mounted on the cabinet. When the cabinet door is opened, the hinge is opened, as shown in Figures 2, 4 and 6, when the hinge cup 1 pulls the first link 2 And the second link 3, the torsion spring 5 hinged with the first link 2 is twisted to generate an elastic force, and the clamping portion 31 of the second link 3 is rotated to the right to drive the rotator 8 and the buffer 9 back to the same. Position, at this time the buffer 9 is uncompressed at the original position. As the hinge is closed, as shown in FIGS. 1 and 5, the hinge cup 1 causes the first link 2 and the second link 3 to rotate, and the clamping portion 31 of the second link 3 drives the rotator 8 to rotate to the left. However, since the middle arm 52 of the torsion spring 5 is pressed against the rubber sleeve 13, the resilience elastic force generated by the torsion spring 5 is transmitted to the rotator 8, so that the rotator 8 can only slowly turn left to the top pressure buffer 9 to make the buffer The device 9 is compressed to achieve the effect of closing the buffer. The structural design of the rotator 8 and the damper 9 of the present application further ensures a small angle buffer of the cabinet door, and the buffer can be buffered when the door is opened more than 5 degrees.
