背景技术Background technique
目前的电力开关柜门板，大多是靠单边铰链固定实现门板的闭合，但对于一些质量较大的门板来说往往会因受力不平衡而导致没有铰链固定的另一边容易掉落或下沉，从而导致门板孔位与柜内电气元器件安装位置对应不上，以及门板容易产生变形的问题。针对现有技术的不足，研发一种电力开关柜门板定位装置显得尤为重要。At present, the door panels of electric switch cabinets are mostly fixed by a single hinge to realize the closure of the door panels. However, for some heavy door panels, the other side without hinges is easy to fall or sink due to unbalanced force. , As a result, the hole position of the door panel does not correspond to the installation position of the electrical components in the cabinet, and the door panel is prone to deformation. In view of the deficiencies in the prior art, it is particularly important to develop a positioning device for a door panel of a power switch cabinet.
