Opening and closing structure and ring main unit
The invention relates to the field of ring main units, in particular to an opening and closing structure and a ring main unit, the opening and closing structure comprises a base and an adjusting plate which are installed on the ring main unit, the adjusting plate is provided with a long-strip-shaped through hole, one end of the through hole is provided with a communicated circular flaring, a stepped shaft is arranged in the through hole in a penetrating mode, and a connecting piece is arranged between the stepped shaft and the base. The stepped shaft is provided with a movable part and a fixed part, the movable part and the fixed part are connected through a smooth transition part, the cross section of the fixed part is larger than that of the movable part, the movable part is used for moving in the through hole, and the flaring is matched with the fixed part to lock the stepped shaft; the stepped shaft is locked through the flaring, it can be guaranteed that the opening and closing mechanism is locked to a certain degree during opening and closing, and therefore a user can use the opening and closing mechanism conveniently.
本发明涉及环网柜领域，尤其涉及一种开合结构及及环网柜，包括安装在环网柜上的底座和调节板，所述调节板上开设有长条形的通孔，所述通孔一端开设有连通的圆形扩口，所述通孔内穿设有阶梯轴，所述阶梯轴与底座之间设置有连接件，所述阶梯轴上设置有移动部和固定部，所述移动部和固定部之间通过圆滑的过渡部连接，所述固定部的横截面大于移动部的横截面，所述移动部用于在通孔内移动，所述扩口与固定部配合用于锁止阶梯轴；通过扩口锁止阶梯轴，能够保证开合机构在开合一定程度上进行锁止，从而方便用户使用。
