Small self-resetting door machine core
The invention provides a small self-resetting door machine core. The small self-resetting door machine core enables a door plate to be balanced in resetting stress, and the service life of the whole structure is long. An upper fixing plate and a lower fixing plate are fixedly arranged on corresponding base bodies correspondingly; a motor connecting shaft protruding downwards is fixedly arranged in the center of the upper fixing plate; the lower portion of the motor connecting shaft is fixedly inserted into a motor shell; the periphery of the motor connecting shaft is sleeved with two first bearings arranged in a spaced mode; an upper fixing block is arranged on the outer rings of the first bearings in a sleeving mode; the radial center area of the upper fixing block is concaved inwards to form an installation groove; a power spring is arranged in the installation groove; the inner end of the power spring is fixedly arranged on the motor connecting shaft; the outer end of the power spring is fixedly arranged in the corresponding position of the upper fixing block; the power spring is arranged in the installation groove in a sleeving mode; the lower portion of the upper fixing block is fixedly connected with the motor shell; a cylinder is fixedly installed on the outer circumference of the upper fixing block and is perpendicularly arranged along the space between the upper fixing plate and the lower fixing plate; and a lower lining is arranged on the radial periphery of the upper surface of the lower fixing plate.
本发明提供了一种小型可自复位道门机芯，其使得门板复位受力均衡，且整个结构的工作寿命长。上固定板和下固定板分别固设于对应的基体上，上固定板的中心位置固设有下凸的电机连接轴，电机连接轴的下部固插于电机壳体，电机连接轴的外周套设有两个间隔布置的第一轴承，上固定块套装于第一轴承的外圈布置，上固定块的径向中心区域内凹形成安装槽，发条弹簧置于安装槽内，发条弹簧的内端固设于电机连接轴，发条弹簧的外端固设于上固定块的对应位置，发条弹簧圈套布置于安装槽，上固定块的下部固接电机壳体，上固定块的外环周固装有圆筒，圆筒沿着上固定板和下固定板之间的空间垂直向布置，下固定板的上表面径向外周设置有下衬套。
