[0006] In a preferred example, the utility model can be further configured as follows: the driving mechanism includes a steel wire rope, the upper and lower ends of the mounting frame are penetrated by through holes for the steel wire rope to pass through, and the two ends of the steel wire rope are respectively fixed to the upper and lower ends of the slider and are arranged in a closed loop.

[0007] In a preferred example, the utility model can be further configured as follows: a push block is vertically slidably connected to the back side of the installation frame, and the steel wire rope passes through the push block and is fixed on the push block.

[0008] In a preferred example, the utility model can be further configured as follows: a sealing tube for the steel wire rope to pass through is embedded in the through hole.

[0009] In a preferred example, the utility model can be further configured as follows: the cleaning rod includes a mounting plate, a sliding tube, cleaning cotton and a spring, the mounting plate is arranged between a pair of the sliding blocks, the sliding tube is arranged on the mounting plate, the cleaning cotton is slidably connected to the sliding tube, and the spring is arranged between the inner wall of the sliding tube and the cleaning cotton.

[0010] In a preferred example, the utility model can be further configured as follows: a retaining ring that abuts against one side of the glass window and a plurality of pressure blocks that abut against the other side of the glass window are arranged in the installation frame, the pressure blocks are slidably connected to the installation frame, and an elastic member that controls the pressure blocks to slide outward is arranged in the installation frame.

[0011] In a preferred example, the utility model can be further configured as follows: a sealing gasket for pressing the glass window is provided on the retaining ring.

[0012] In summary, the utility model has the following beneficial effects:

[0013] 1. By setting a cleaning rod that can slide back and forth, when a fire occurs, the cleaning rod can be controlled to slide vertically from the outside, thereby realizing automatic cleaning of the inside of the glass window, making it convenient for rescue personnel to observe the situation in the fire scene and facilitate rescue operations;

[0014] 2. By setting up a cleaning rod with a unique structure, the cleaning cotton can always be pressed against the glass window, thus achieving stable cleaning of the glass window surface;

[0015] 3. By setting up easy-to-replace glass windows, the maintenance and replacement of glass windows becomes easier and more convenient, thus improving the practicality of fire doors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, a fireproof door structure comprises a door frame 1 and a door leaf 2. A mounting frame 3 is embedded in the door leaf 2, and a glass window 4 is arranged in the mounting frame 3.

[0024] like Figure 2 , Figure 3 As shown, both sides of the inner side of the installation frame 3 are vertically provided with slide grooves 31, and sliders 32 are vertically slidably connected in the slide grooves 31. A cleaning rod 5 is horizontally arranged between a pair of sliders 32 to abut against the glass window 4, and a driving mechanism 6 for controlling the vertical sliding movement of the sliders 32 is arranged on the outer side wall of the installation frame 3.

[0025] like Figure 2 , Figure 3 As shown, the driving mechanism 6 includes a steel wire rope 61 and a push block 62 , and a through hole 33 for the steel wire rope 61 to pass through is provided at the upper and lower ends of the mounting frame 3 , and a sealing tube 34 for the steel wire rope 61 to pass through is embedded in the through hole 33 .

[0026] like Figure 2 , Figure 3 As shown, the two ends of the wire rope 61 are respectively fixed to the upper and lower ends of the slider 32 and are arranged in a closed loop. The push block 62 is vertically slidably connected to the back side of the installation frame 3, and the wire rope 61 passes through the push block 62 and is fixed on the push block 62.

[0027] When a fire occurs indoors and rescue is needed, the push block 62 is pushed to slide vertically. At this time, the push block 62 drives the wire rope 61 to move synchronously, and pulls the slider 32 to slide vertically back and forth. At this time, the slider 32 drives the cleaning rod 5 to move synchronously, and automatically cleans the inside of the glass window 4, ensuring that the rescue personnel can clean the glass window 4 from the outside, so as to clearly observe the situation of the fire scene, which is convenient for rescue operations.

[0028] like Figure 4 As shown, the cleaning rod 5 includes a mounting plate 51, a sliding tube 52, a cleaning cotton 53 and a spring 54. The mounting plate 51 is arranged between a pair of sliders 32, the sliding tube 52 is arranged on the mounting plate 51, the cleaning cotton 53 is slidably connected to the sliding tube 52, and the spring 54 is arranged between the inner wall of the sliding tube 52 and the cleaning cotton 53.

[0029] When the cleaning rod 5 is working, under the thrust of the spring 54, the cleaning cotton 53 can always be pressed against the glass window 4, so that the inner wall of the glass window 4 can be stably cleaned, ensuring that the rescue personnel can clearly observe the situation at the fire scene, facilitating rescue operations.

[0030] like Figure 5As shown, a retaining ring 35 abutting against one side of the glass window 4 and a plurality of pressing blocks 36 abutting against the other side of the glass window 4 are arranged in the mounting frame 3, and a sealing gasket 37 for pressing the glass window 4 is arranged on the retaining ring 35 to increase the sealing performance and prevent smoke leakage. The pressing blocks 36 are slidably connected to the mounting frame 3, and an elastic member 38 for controlling the pressing blocks 36 to slide outward is arranged in the mounting frame 3.

[0031] When the glass window 4 needs to be installed, the glass window 4 is placed in the installation frame 3, and then the glass window 4 is pressed to slide inwards, at which time the glass window 4 presses the pressing block 36 to slide inwards and embed into the installation frame 3. When the glass window 4 hits the retaining ring 35, the pressing block 36 automatically pops out and presses the glass window 4, thereby clamping and fixing the glass window 4, and the glass window 4 can be quickly replaced.

[0032] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
