The invention relates to an automatic security door with a door leaf weight balance structure, and relates to the field of automatic security doors. On the basis of an original security door, a rotaryshaft and a supporting arm are additionally arranged, two ends of the supporting arm are separately connected with the rotary shaft and a door leaf, pull force generated during the rotation of the supporting arm forms counterclockwise torque which is equal to clockwise torque generated by the weight center of the door leaf and counteracts each other so as to ensure that the door leaf is not deflected, and the balance state of an open fan composed of a moving column and the door leaf in the process of opening and closing is ensured; and the structure enables the external driving force needed when the door leaf moves to the left and right to be less, the structure is simpler, the manufacturing, installation, debugging and maintenance are more convenient, and the cost is lower.
一种带有门扇重量平衡结构的自动防盗门，涉及自动防盗门领域。在原有防盗门的基础上增加旋转轴和支撑臂，支撑臂两端分别与旋转轴和门扇连接，在支撑臂旋转时产生的拉力形成反时针扭矩，与门扇重量中心产生的顺时针扭矩相等相互抵消，从而保证门扇不会偏斜，保证了移动柱和门扇组成的开启扇在开启和关闭过程中的平衡状态，该结构使门扇左右移动时所需外驱动力更小，且结构更简单，制造、安装、调试和维修更加方便，成本更低。
