Energy-saving polyurethane double-layer fireproof composite board
The invention discloses an energy-saving polyurethane double-layer fireproof composite board which comprises a composite board body, a protection board is installed on the front vertical face of the composite board body, a fireproof frame is installed in the middle of the composite board body, an L-shaped welding piece is welded to the middle of the bottom end of the fireproof frame, and a spring is installed at one end of the L-shaped welding piece. A first hinge piece is installed at one end of the spring, and a second hinge piece is hinged to one end of the first hinge piece. According to the energy-saving polyurethane double-layer fireproof composite board, the outer wall of the first push rod makes contact with the tail end of the outer wall of the lead screw, when the first push rod moves upwards, the lead screw can be driven to rotate, after the lead screw rotates, a transmission wheel at the outer end of the lead screw drives a connecting wheel to rotate through a transmission belt, and rotation control over a main shaft can be achieved through rotation of the connecting wheel; the main shaft is matched with the speed reduction shaft to achieve the speed reduction protection effect.
本发明公开了一种节能型聚氨酯双层防火复合板材，包括复合板，所述复合板的前立面安装有防护板，所述复合板的中间部位安装有防火框，所述防火框的底端居中部位焊接有L形焊接片，所述L形焊接片的一端安装有弹簧，所述弹簧的一端安装有铰接件一，所述铰接件一的一端铰接有铰接件二。该一种节能型聚氨酯双层防火复合板材，推杆一的外壁和丝杆的外壁尾端接触，在推杆一向上位移的时候，将会带动丝杆进行转动，在丝杆转动后，其外端的传动轮通过传动带带动连接轮进行旋转，而连接轮的转动，将会实现主轴的转动控制，主轴配合上减速轴将会实现降速保护效果。
