The invention discloses a mounting and fixing device for a classroom roller shutter. The mounting and fixing device comprises a left end L-shaped support and a right end L-shaped support which are fixed to the vertical face of a wall at equal height and used for lifting the roller shutter, screw holes A are formed in vertical plates at the outer side ends of the L supports, concave areas are arranged on the end vertical surfaces of a left end cover and a right end cover of the roller shutter housing, bolts penetrate through the screw holes A from outside to inside and then are connected with nuts C, the inner ends of the nuts C are placed in the concave areas of the end covers or separated from the concave areas in the left-right direction, nuts B attached to the L-shaped support end vertical plates facilitate stabilization of the bolts, the proper widths of the left L-shaped support and the right L-shaped support allow a normal operation error to exist in the distance between the left L-shaped support and the right L-shaped support when the wall facade is fixed. According to the mounting and fixing device, the nuts C invade into the concave areas of the end covers to forcibly prevent the product from tripping, so that the personal safety of ground personnel is reliably ensured and the product maintenance requirement is met.
一种教室卷帘的安装固定装置，包括等高固定于墙立面的用于托举卷帘的左、右端L托，L托外侧端立板载有螺孔A；卷帘罩壳左、右端盖的端立面设有内凹区；螺栓自外向内穿螺孔A后连接螺母C,螺母C内端或置入端盖内凹区，亦可与内凹区左右向分离，贴靠L托端立板的螺母B利于螺栓稳固。左、右L托的适当宽度允许其在墙立面固定时的间距存在正常操作误差。螺母C侵入端盖内凹区强制阻挡产品跳脱，可靠保证地面人员的人身安全，及满足产品维护需要。
