And the fireproof window has good fireproof performance through the performance of its main body structure material. However, when the fireproof window is subjected to high temperature for a long time, the internal structure of the glass, which is the main component structure of the fireproof window, is prone to split, and then the glass of the fireproof window will crack, thus causing certain potential safety hazards to the environment inside and outside where the fireproof window acts. Therefore, a protection structure for a fireproof window is proposed for the above problems. Content of the Utility Model

[0008] As a further optimized content of the present utility model, wherein: the card slot opened on the inner side of the metal rod faces downward towards the magnet strip, the card slot and the magnet strip are engaged with each other, and the magnet strip and the metal rod are magnetically attracted to each other.
[0009] As a further optimized content of the present utility model, wherein: two limiting rings are symmetrically arranged on the outer side of the metal rod, the rotating wheel is arranged between the limiting ring and the fixing frame, and the card slot is arranged between the two limiting rings.
[0010] As a further optimized content of the present utility model, wherein: two memory springs are symmetrically and fixedly connected to the outer side of the diamond mesh, the diamond mesh is wound around the outer side of the rotating shaft, and the diamond mesh is arranged inside the fixing shell.

The stretched memory spring gradually contracts and gradually returns to a spiral shape, and the memory spring is passively wound around the rotating wheel, so that the rotating wheel rotates on the metal rod.

Thus, the diamond mesh plays a role in covering and protecting the glass of the fireproof window, effectively preventing a large safety hazard from occurring inside and outside the environment where the fireproof window acts when the glass of the fireproof window cracks.

[0024] Please refer to Figures 1-6 , the present utility model provides a technical solution:
[0025] A protection structure for a fireproof window, including glass 1 and a frame 2. The glass 1 is fixedly connected to the outside of the frame 2, and a traction mechanism 3 is fixedly connected to the outside of the frame 2. The traction mechanism 3 includes a fixed frame 31. The inside of the fixed frame 31 is fixedly connected to a metal rod 32. The outside of the metal rod 32 is fixedly connected to a card slot 33. The outside of the metal rod 32 is fixedly connected to a limit ring 34. A rotating wheel 35 is slidably connected to the outside of the metal rod 32. The outside of the rotating wheel 35 is fixedly connected to a memory spring 36. A protection mechanism 4 is fixedly connected to the outside of the frame 2. The protection mechanism 4 includes a fixed shell 41. The inside of the fixed shell 41 is rotatably connected to a rotating shaft 42. A hexagonal hole 43 is opened inside the rotating shaft 42. The outside of the rotating shaft 42 is fixedly connected to a diamond mesh 44. The outside of the diamond mesh 44 is fixedly connected to a magnet strip 45.
[0026] As a further implementation of this solution, there are two metal rods 32 in total. The metal rods 32 are symmetrically arranged on both sides of the frame 2. The metal rods 32 are arranged directly above the fixed shell 41. There are two fixing brackets 31 symmetrically on the outside of the metal rods 32, which facilitates the fixation of one end of the memory spring 36 by the rotating wheel 35;
[0027] As a further implementation of this solution, the card slot 33 opened on the inner side of the metal rod 32 faces downward towards the magnet strip 45. The card slot 33 is engaged with the magnet strip 45, and the magnet strip 45 is magnetically attracted to the metal rod 32, which facilitates the diamond mesh 44 to be laid flat and cover the outside of the glass 1;
[0028] As a further implementation of this solution, there are two limiting rings 34 symmetrically arranged on the outside of the metal rod 32. The rotating wheel 35 is arranged between the limiting ring 34 and the fixing bracket 31, and the card slot 33 is arranged between the two limiting rings 34, which can limit the position of the rotating wheel 35;
[0029] As a further implementation of this solution, there are two memory springs 36 symmetrically and fixedly connected to the outside of the diamond mesh 44. The diamond mesh 44 is wound around the outside of the rotating shaft 42. The diamond mesh 44 is arranged inside the fixed shell 41, and the diamond mesh 44 can be stretched by the contraction of the memory spring 36;
[0030] As a further implementation of this solution, the length and width of the laid flat diamond mesh 44 are between the length and width of the outside of the frame 2 and the length and width of the glass 1. The width of the diamond mesh 44 is much larger than the width of the magnet strip 45, which can ensure that the laid flat diamond mesh 44 completely covers the outside of the glass 1;
[0031] As a further implementation of this solution, the two ends of the rotating shaft 42 are in the same vertical plane as the two sides of the fixed shell 41 respectively. Only one end of the rotating shaft 42 is provided with a hexagonal hole 43. One end of the hexagonal hole 43 is in the same vertical plane as the rotating shaft 42. The hexagonal hole 43 can be engaged with a fixed-size hexagonal wrench, and the rotation of the rotating shaft 42 in the fixed shell 41 can be controlled through the hexagonal hole 43, so that the diamond mesh 44 is wound around the rotating shaft 42.
[0032] Workflow: When using this fireproof window, if a relatively high temperature is generated inside and outside the environment where the fireproof window acts, the memory spring 36 outside the fireproof window frame 2 will be deformed by heat, causing the originally stretched memory spring 36 to gradually contract. The contraction of the memory spring 36 will gradually change into a spiral shape. At the same time, since some segments of the memory spring 36 are wound around the runner 35, the gradually contracting memory spring 36 will gradually contract and wind around the runner 35, and push the runner 35 to rotate on the metal rod 32, thereby fixing the runner 35 on the horizontal plane so that the other end of the memory spring 36 always moves closer to its contraction. Furthermore, the memory spring 36 can drive the wire mesh 44 fixedly connected thereto to move together. Since the wire mesh 44 is wound around the rotating shaft 42 rotatably connected to the inside of the fixed shell 41, the stretching of the memory spring 36 on the wire mesh 44 can drive the rotating shaft 42 to rotate in the fixed shell 41. At this time, the wire mesh 44 can be gradually laid flat on the outside of the glass 1. When the wire mesh 44 moves closer to the metal rod 32 as the memory spring 36 contracts, the magnet strip 45 fixedly connected to the wire mesh 44 also moves closer to the metal rod 32 until the magnet strip 45 is engaged in the card slot 33 opened inside the metal rod 32, and the magnet strip 45 adsorbs to the metal rod 32. At this time, the position of the wire mesh 44 can be fixed and restricted, and at this time, the wire mesh 44 completely covers the outside of the glass 1 flatly. The wire mesh 44 can protect the glass 1 that cracks under the action of high temperature, effectively reducing the safety hazard caused by the fragments of the cracked glass 1 to the inside of the environment where this fireproof window acts.
[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
