Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses steel frame wooden sash heat insulation fireproof door. Referring to fig. 1-3, a steel frame and wooden sash heat insulation fireproof door comprises a top plate 1, wherein a door frame 2 is fixedly connected to the lower end of the top plate 1, a door plate 3 is rotatably connected to the left side of the door frame 2, an arc-shaped chute 12 is formed in the lower end of the top plate 1, a sliding block 11 is slidably connected to the inside of the arc-shaped chute 12, the lower end of the sliding block 11 is fixedly connected to the upper end of the door plate 3, a first cavity 4 is formed in the top plate 1 and located on the left side of the arc-shaped chute 12, a spring 5 is fixedly connected to the inside of the first cavity 4, a guide block 6 is fixedly connected to the right side of the spring 5, a second cavity 7 is formed in the top plate 1 and located at the rear end of the right side of the first cavity 4, a memory metal 8 is fixedly connected to the second cavity 7, a clamping block 9 is fixedly connected to the front end of the memory metal 8, an opening matched with the guide block 6 is formed in the clamping block 9, and a rotating roller 10 is uniformly and rotatably connected to the front end of the left side of the clamping block 9;
