[0006] Furthermore, the power assembly includes a screw rod rotatably mounted between two fixed plates, and a motor for driving the screw rod to rotate is mounted on the outer side of one of the fixed plates.

[0007] Furthermore, the screw rod passes through the movable block, and the driving block is threadedly connected to the screw rod.

[0008] Furthermore, a mounting groove is provided at the front end of the movable block, the driving block is located inside the mounting groove, and limit blocks are symmetrically fixed on both sides thereof, and limit grooves matching with the limit blocks are provided on both sides of the mounting groove.

[0009] Furthermore, the front and rear sides of the box body are provided with sliding grooves adapted to the fixing blocks.

[0010] The advantages of the utility model over the existing technology are: the utility model rotates the screw rod in the forward direction through the handle, so that the driving block moves outward and separates from the screw rod, and the handle moves the movable block up and down along the slide groove to open the window sash; after opening the window sash, the handle is twisted in the reverse direction to make the driving block mesh with the screw rod, and the window sash can be in a normally open state. The utility model can open the window sash when the circuit or motor is damaged, and can keep the window sash in a normally open state, which is highly safe and practical.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 5 As shown, a fire-fighting electric window opener has a window opener body symmetrically installed on both sides of a frame 1, a window sash 2 is installed on the top of the frame 1, and the window opener body includes a box body 3, and fixed plates 4 are fixedly connected to the upper and lower sides of the box body 3. The two fixed plates 4 are provided with movable blocks 5, and a power component for driving the movable blocks 5 to move is installed inside the box body 3. The power component includes a screw rod 11 rotatably installed between the two fixed plates 4, and a motor 12 for driving the screw rod 11 to rotate is installed on the outer side of one of the fixed plates 4.

[0019] A movable driving block 6 is installed inside the movable block 5, an arc groove is provided at one end of the driving block 6, and a thread is provided inside the arc groove, a screw rod 11 runs through the movable block 5, and the driving block 6 is threadedly connected to the screw rod 11, a mounting groove is provided at the front end of the movable block 5, the driving block 6 is located inside the mounting groove, and limit blocks 13 are symmetrically fixed on both sides of the movable block 5, and limit grooves compatible with the limit blocks 13 are provided on both sides of the mounting groove, fixed blocks 7 are fixed on the front and rear sides of the movable block 5, and sliding grooves compatible with the fixed block 7 are provided on the front and rear sides of the box body 3, a screw rod 8 is installed through the middle of the fixed block 7 on the front side, one end of the screw rod 8 is rotatably connected to the driving block 6, and the other end is fixedly connected to a handle 9, and the screw 8 is threadedly connected to the fixed block 7, and a connecting rod 10 is hinged between the other fixed block 7 and the window sash 2.

[0020] In specific use, the motor 12 drives the screw rod 11 to rotate, which can prompt the driving block 6 to move up and down along the screw rod 11. The driving block 6 drives the movable block 5 to move. The movable block 5 drives the connecting rod 10 to move through the fixed block 7 on the rear side to realize the opening or closing of the window sash 2.

[0021] When a fire causes a circuit break or the motor 12 is damaged, the screw rod 8 is rotated forward by the handle 9, so that the screw rod 8 drives the driving block 6 to move outward, so that the driving block 6 is separated from the screw rod 11. At this time, the movable block can be moved up and down along the slide groove by the handle 9 to open the window sash 2. After opening the window sash 2, the handle 9 is twisted in the reverse direction to make the driving block 6 engage with the screw rod 11. At this time, the window sash 2 can be in a normally open state.
